其它 1、本課題的的研究目的和意義： 研究目的：

研究意義： 通過此次設(shè)計(jì)，是對(duì)我們這幾年所學(xué)的知識(shí)一個(gè)綜合性考評(píng)，讓我們明白自己的不足之處，同時(shí)也是一次理論聯(lián)系實(shí)踐的設(shè)計(jì)，對(duì)我們踏入社會(huì)找工作也很有幫助。 2、 文獻(xiàn)綜述（國(guó)內(nèi)外研究情況及其發(fā)展）： （1） 現(xiàn)代機(jī)械工業(yè)的生產(chǎn)特點(diǎn) 隨著科學(xué)技術(shù)的進(jìn)步和生產(chǎn)力的發(fā)展，國(guó)民經(jīng)濟(jì)各部分不斷要求機(jī)械工業(yè)提供先進(jìn)的技術(shù)裝備，研制新的產(chǎn)品品種，以滿足國(guó)民經(jīng)濟(jì)持續(xù)發(fā)展和人發(fā)生活不斷提高的需要，這樣一來，促使機(jī)械工業(yè)的生產(chǎn)形式發(fā)生了顯著的變化，即多品種、中小批量生產(chǎn)逐漸占了優(yōu)勢(shì)。國(guó)際生產(chǎn)研究協(xié)會(huì)的統(tǒng)計(jì)表明，目前中小批、多品種生產(chǎn)的工件品種已占工件種類總數(shù)的85%左右。現(xiàn)代生產(chǎn)企業(yè)所制造的產(chǎn)品品種經(jīng)常更新?lián)Q代，以適應(yīng)市場(chǎng)的需求與競(jìng)爭(zhēng)。于是，現(xiàn)代企業(yè)生產(chǎn)便面臨以下問題。 ① 通常小批量生產(chǎn)采用先進(jìn)的工藝方法和專用工藝裝備是不經(jīng)濟(jì)的，但對(duì)于高、精、尖產(chǎn)品而言，不采用這種手段又無法達(dá)到規(guī)定的技術(shù)要求。 ② 現(xiàn)行生產(chǎn)準(zhǔn)備工件往往需要較長(zhǎng)的時(shí)間，花費(fèi)的人力、物力較大，趕不上產(chǎn)品更新?lián)Q代的步伐。 ③ 由于產(chǎn)品更新越來越快，使用傳統(tǒng)的專用夾具，勢(shì)必造成積壓浪費(fèi)。 為此，除了在產(chǎn)品結(jié)構(gòu)設(shè)計(jì)和產(chǎn)品生產(chǎn)工藝方面進(jìn)行改革之外，在工藝裝備方面也必須改革其狹隘的專用性，使之適應(yīng)新的生產(chǎn)特點(diǎn)的需要。 （2） 機(jī)床夾具的現(xiàn)狀 夾具最早出現(xiàn)在18世紀(jì)后期。隨著科學(xué)技術(shù)的不斷進(jìn)步，夾具已從一種輔助工具發(fā)展成為門類齊全的工藝裝備。 在批量生產(chǎn)中，企業(yè)都習(xí)慣于采用傳統(tǒng)的專用夾具，一般在具有中等生產(chǎn)能力的工廠里，約擁有數(shù)千甚至近萬套專用夾具；在多品種生產(chǎn)的企業(yè)中，每隔年就要更新%的專用夾具，而夾具 的實(shí)際磨損量?jī)H為%，這些夾具往往留下來又很難得重復(fù)使用，拋棄它們又實(shí)在可惜，因此造 成很大的浪費(fèi)。這些都是一直困擾企業(yè)的現(xiàn)實(shí)問題。 近年來，數(shù)控機(jī)床、加工中心、組成技術(shù)、柔性制造系統(tǒng)（FMS）等新加工技術(shù)的應(yīng) 用，對(duì)機(jī)床夾具提出了如下新的要求： ① 能訊速而方便地裝備新產(chǎn)品的投產(chǎn)，以縮短生產(chǎn)準(zhǔn)備周期，降低生產(chǎn)成本； ② 能裝夾一組具有相似性特征的工件； ③ 能適用于精密加工的高精度機(jī)床夾具； ④ 能適用于各種現(xiàn)代化制造技術(shù)的新型機(jī)床夾具； ⑤ 采用以液壓站等為動(dòng)力源的高效夾緊裝置，以進(jìn)一步減輕勞動(dòng)強(qiáng)度和提高勞動(dòng)生產(chǎn)率； ⑥ 提高機(jī)床夾具的標(biāo)準(zhǔn)化程度。 這些都是擺在工藝技術(shù)人員面前的新課題、新任務(wù)。 （3） 現(xiàn)代機(jī)床夾具的發(fā)展方向 為了適應(yīng)現(xiàn)代機(jī)械工業(yè)向高、精、尖方向發(fā)展的需要和多品種、小批量生產(chǎn)的特點(diǎn)，現(xiàn)代機(jī)床夾具的發(fā)展方向主要表現(xiàn)為標(biāo)準(zhǔn)化、精密化、高效化和柔性化四個(gè)方面。 ① 標(biāo)準(zhǔn)化。機(jī)床夾具的發(fā)標(biāo)準(zhǔn)化與通用化是相互聯(lián)系的兩個(gè)方面。目前我國(guó)已有夾具零件及部件的國(guó)家標(biāo)準(zhǔn)：GB/T2148～T2259—91以及各類通用夾具、組合夾具標(biāo)準(zhǔn)等。機(jī)床夾具的標(biāo)準(zhǔn)化有利于夾具的商品化生產(chǎn)，有利于縮短生產(chǎn)準(zhǔn)備周期，降低生產(chǎn)總成本。 ② 精密化。隨著機(jī)械產(chǎn)品精度的日益提高，勢(shì)必相應(yīng)提高了對(duì)夾具的精度要求。精密化夾具的結(jié)構(gòu)類型很多，例如用于精密分度的多齒盤，其分度精度可達(dá)″；用于精密車削的高精度三瓜自定心卡盤，其定心精度為5。 ③ 高效化。高效化夾具主要用來減少工件加工的基本時(shí)間和輔助時(shí)間，以提高勞動(dòng)生產(chǎn)率，減輕工人的勞動(dòng)強(qiáng)度。常見的高效化夾具有自動(dòng)化夾具、高速化夾具和具有夾緊力裝置的夾具等。例如，在銑床上使用電動(dòng)虎鉗裝夾工件，效率可提高5倍左右；在車床上使用高速三瓜自定心卡盤，可保證卡瓜在試驗(yàn)轉(zhuǎn)速為9000r/min的條件下仍能牢固地夾緊工件，從而使切削速度大幅度提高。目前，除了在生產(chǎn)流水線、自動(dòng)線上配置相應(yīng)的高效、自動(dòng)化夾具外，在數(shù)控機(jī)床上，尤其在加工中心上出現(xiàn)了各種自動(dòng)裝夾工件夾具以及自動(dòng)更換夾具的裝置，充分發(fā)揮了數(shù)控機(jī)床的效率。 ④ 柔性化。機(jī)床夾具的柔性化與機(jī)床的柔性化相似，它是指機(jī)床夾具通過調(diào)整、組合等方式，以適應(yīng)工藝可變因素的能力。工藝的可變因素主要有：工序特征、生產(chǎn)批量、工件的形狀和尺寸等。具有柔性化特征的新型夾具種類主要有：組合夾具、通用可調(diào)夾具、成組夾具、模塊化夾具、數(shù)控夾具等。為適應(yīng)現(xiàn)代機(jī)械工業(yè)多品種、中小批量生產(chǎn)的需要，擴(kuò)大夾具的柔性化程度，改變專用夾具的不可拆結(jié)構(gòu)為可拆結(jié)構(gòu)。發(fā)展可調(diào)夾具結(jié)構(gòu)，將是當(dāng)前夾具發(fā)展的主要方向。 3、 本課題的主要研究?jī)?nèi)容（提綱）和成果形式： 研究的主要內(nèi)容 設(shè)計(jì)齒輪泵泵體機(jī)械加工工藝規(guī)程的設(shè)計(jì)，制作相關(guān)工藝文件。就至少兩道重點(diǎn)工序設(shè)計(jì)機(jī)械加工夾具，進(jìn)行設(shè)計(jì)計(jì)算并繪制夾具裝配圖和零件圖，撰寫設(shè)計(jì)說明書。 預(yù)期成果 通過本課題的研究，完成齒輪泵泵體零件的三維圖、二維圖的繪制，查閱相關(guān)資料，繪制出毛坯圖，擬定加工方案，編寫工藝過程卡及加工工序卡，制定兩套專用夾具方案，最終完成畢業(yè)論文的撰寫。 4、擬解決的關(guān)鍵問題： 1、需查閱資料將齒輪泵泵體零件圖補(bǔ)充完整。（比如：尺寸、表面粗糙度、材料等） 2、制定合理的工藝路線 3、夾具的定位方案、夾緊方案 4、工時(shí)定額的計(jì)算 5、研究思路、方法和步驟： 研究方法：1.明確設(shè)計(jì)任務(wù)，收集研究設(shè)計(jì)的原始資料 A：加工零件的零件圖、毛坯圖及加工工藝過程，所設(shè)計(jì)夾具應(yīng)有的工序圖，并了解該工序所使用的設(shè)備、刀具、量具、其他輔具以及該工序的加工余量、切削用量、加工要求、生產(chǎn)節(jié)拍等參數(shù)。 B：了解零件的生產(chǎn)類型，就是決定夾具采用簡(jiǎn)單結(jié)構(gòu)或復(fù)雜結(jié)構(gòu)的依據(jù)。若屬大批量生產(chǎn)，則力求夾具結(jié)構(gòu)完善、生產(chǎn)率高 或是單件小批量生產(chǎn)或急于應(yīng)付生產(chǎn)，則夾具結(jié)構(gòu)應(yīng)簡(jiǎn)單，以便迅速制造交付使用。 C：收集該夾具所用機(jī)床的資料，主要指與夾具連接部分的安裝尺寸。如銑床夾具要安裝在工作臺(tái)上，要收集工作如大小，工作如T形槽及槽距，以及機(jī)床的技術(shù)參數(shù)。 D：收集所使用刀具的資料如刀具的精度、安裝方式、使用要求及技術(shù)條件等。 E：收集國(guó)內(nèi)外同類型夾具資料，吸收其中先進(jìn)而又能結(jié)合本廠情況的合理部分。 F：了解本廠制造夾具的能力和使用的條件，如夾具制造的條件及精度水平，有無壓縮空氣壓值等。 G：收集有關(guān)夾具部件的標(biāo)準(zhǔn)（包括國(guó)標(biāo)、部標(biāo)、企標(biāo)、廠標(biāo)），典型夾具結(jié)構(gòu)圖冊(cè)等。 2.確定夾具結(jié)構(gòu)方案，繪制結(jié)構(gòu)草圖 A：根據(jù)工件加工尺寸、要求和開關(guān)，確定工件的定位方式，選擇或設(shè)計(jì)定位元件，計(jì)算定位誤差。 B：確定刀具的引導(dǎo)方式及引導(dǎo)元件（指鉆夾具、鏜夾具）。 C：確定工件夾緊方式 ，選擇或設(shè)計(jì)夾緊機(jī)構(gòu)，計(jì)算夾緊力。 D：確定其他裝置（如分度裝置、頂出裝置）的結(jié)構(gòu)型式。 E：確定和設(shè)計(jì)其他結(jié)構(gòu)，如銑床夾具與機(jī)床的連接裝置、對(duì)刀裝置。 在確定夾具結(jié)構(gòu)的各組成部分時(shí)，可提出幾種不同方案，分別畫出草圖，進(jìn)行分析比較，從中選擇出合理方案。 3. 繪制夾具總圖 A：繪制夾具總圖，盡量按1：1繪制，以保證直觀性。 B：主視圖盡量符合操作者的正面位置。

However, the design of the products, especially mechanical products in the design means, failed to keep pace with the needs of the times. At present, computer-aided product design drawings, design, manufacturing, production planning has been a relatively extensive and in-depth study and achieved initial results, and product development programs of the early computer-aided design is far from meeting the needs of the design. To this end, the author read a lot of literature on the basis of a summary of the design and scholars at home and abroad to design the method used, and discussed the various methods of organic link between product design and mechanical Computer trend of development. Under the current domestic and foreign scholars to design machinery design methods used by the main features of the program can be summed up modern design for the following four major types. 1, systematic design method Systematic design the main features are: design as from a number of design elements of a system, every design element of independence, there are various elements of the organic links and a level of all the design elements Combined, you can design systems to achieve the task. Systematic design idea in the 1970s by the German scholar Professor Pahl and Beitz, a system based on the theory, developed a design of the general pattern, and advocate of the design work should be rational. German Engineers Association in this on the basis of design, develop standards VDI2221 "technology systems and product development design methods. The development of the product design process of mechanical model, basically follow the German standards VDI2221 the design. In addition, many of our product design and scholars in the programme design and also learn from other developed countries cited the systematic design, which is representative: (1) The user needs as the product concept of functional characteristics, structural design and part design, process planning, operations control, and so on the basis of the product development process of the macro, the use of Quality Function layout methods, systems and information needs of users will be reasonable and effective And converted to the various stages of product development objectives and operations control technology means a point of order. (2) products as organisms on the level of life, and life systems through the use of the product design process can demand level of success and realize the concept of functional requirements of the specific levels and product design level. At the same time using the system icons to life the abstract expression of the functional requirements of products, product features a system structure. (3) the mechanical design system in the application of science into two basic questions: First, to design products as a system to process, to determine the best of its components (modules) and their mutual relations and the other is the product design Process as a system, according to the design objectives, correct and reasonable to determine the design of all aspects of the work and the various design stage. As each designer to study issues and to consider the perspective of the different emphases, to design a programme of specific research methods also differ. Here are some representative of the systematic design methods. 1.1 design elements of With five design elements (functions, effects, effects of vector, shape and surface elements parameters) described "product solution" that a product design elements of the five identified, all the characteristics of products and value characteristics already identified. Chinese scholars have also adopted similar design methods described product of the original understanding. 1.2 graphical modeling law Development of the "design analysis and guidance systems" KALEIT, with a clear level of the graphic description of the product structure and functions related to the abstract information, and the system structure and function graphical modeling, as well as functional connections between the layers. Will be assisted design divided into two methods and information exchange, the use of Nijssen information analysis methods can be used graphic symbols, with a variety of semantic model structure, the integration can be described conditions can be divided into binding type, can relations between any combination of features , Will design solutions and information technology integration, the design process to achieve a different level of abstraction of information between the graphical modeling. The literature [11] semantic network design as a design tool in the development of the semantic network design ASK, using nodes and a network of lines describing the design, said node components of the unit (such as the design tasks, functions, components Or processing equipment, etc.), and lines used to adjust the definition node between different semantic relations, which in the design process for all the activities and results of pre-built model, the early design requirements to the definition of a specific structure can be described by the Relations between the definition of the expression, and a computer-aided design process from abstract to concrete leap. 1.3 "idea" - "design" law Will be divided into product design "concept" and "design" in two stages. "Concept" stage of the task is to seek, select and design portfolio to meet the requirements of the original understanding of tasks. "Design" stage of work is the concrete realization of the original understanding of the conceptual stage. The programme will be "ideas" for the specific description: According to a suitable functional structure, designed to meet the requirements of the mandate of the original understanding. Functional structure of the sub-function by "structural elements" to achieve, and "structural elements" of the physical connection between the definition of "functional carrier", "functional carrier" and "structural elements" and formation of the interaction between the functional diagram ( Mechanical movement diagram). Programme of "design" is based on functional diagram, the first qualitative description of all the "functional carrier" and "structural elements", then all the quantitative description of "structural elements" and connecting pieces ( "functional vector") the shape and location have The structure of. Roper, H. use of graph theory theory, the help from his definition of "total design unit (GE)", "structure elements (KE)", "functional structure elements (FKE)", "connecting structure elements (VKE)", "Structural parts (KT)", "structural elements parts (KET)" concept, and describes elements of size, location and transmission parameters of the relationship between the number of thumbs, the design expert intuitive way to design a formal Description of the formation of effective application of existing knowledge of methods, and applied to the "idea" and "design" stage. From the design methodology of the point of view, the design task will be clear after the design work is divided into three steps: 1) access to functions and functional structure (referred to as "functional"), 2) find effects (referred to as the "effect"); ) To find structure (referred to as "the configuration of the Rules"). And described by the following four strategies Mechanical Product concept stage of the process: Strategy 1: were considered "functional" and "effect" and "configuration rules." Therefore, we can work in various steps to create variations in the respective programmes, resulting in the original understanding of the broad spectrum. Strategy 2: "effect" and "configuration rules" (including the designer to create the rules) association, to consider a separate function (usually associated with the design task). At this point, to identify the typical configuration rules and their effects need to have a wealth of experience, the programme spectrum far less than a strategy of the programme spectrum. Strategy 3: "functional" and "effect", "configuration rules" are closely related. Applicable to the function, and the configuration of the rules of no choice, with special requirements of the areas, such as ultra-small machinery, large machinery, high-value function parts, and those with special requirements of the functional components, and so on. Strategy 4: In view of the structural design requirements of the solution. The strategy starting from the existing parts, through different parts of the order and connection, was expected to function. 1.4 Matrix Design In the programme design process used in "requirement - to" logic tree ( "or" tree) described requirements, the relationship between the function, to satisfy the requirements of functional design solution set, a different design. According to "request - to" logic tree establishment of a "request - to" association matrix, meet the requirements necessary to describe the complex relationship between function, expressed functional requirements and the relationship between the one-to-one. Kotaetal will matrix as a mechanical system design basis, the mechanical system design space as a functional decomposition of space, only that each sub-space design of a module, in the abstract phase of the high-level, with each module design movement conversion matrix And a vector for the operation of restraint that in the abstract phase of the low-rise, each module design parameters were expressed as a matrix and the equation of motion. 1.5 bond graph Law Will form a system components into the function to generate energy, energy consumption, changing energy forms, such as various types of energy transmission and use of bond graph of the function of the components that will be based on the functions of the model and bonding with plans to achieve functional The automatic generation of structural and functional structure and bonding between the automatic conversion plans to seek bond graph generated by a number of design methods. 2, modular design structure From the perspective of planning products: the definition of its mandate to design features of the product structure is based on the use of existing products (such as GM parts components, etc.) described the design task, that is, when the mandate of decomposition on each task to consider whether there is the corresponding Solutions products, so that in the planning stages of product design tasks to eliminate the contradictions that might exist in the early forecast production capacity, costs and the development of the process of designing the plan adjustable, which can improve the design efficiency and design of reliability, At the same time also reduce the cost of new products. Feldmann will describe the function of the design task is divided into four levels of product structure, (1) products → (2) functional components → (3) main function components → (4) functional components. And the use of application-oriented features of the directory structure, a more specific functional components of the qualitative and quantitative description. At the same time developed for early in the product development and design tools used by early STRAT. Machinery specialized for most of that function can be used existing product solutions and new solutions with only a small number of special features, therefore, for the use of mechanical design features of the product structure, machinery specialized for the evaluation of the design, manufacture risk is very beneficial. Functional Analysis of the products promoted on the basis of the product is broken down into a function of one or more of the basic modular structure, through the selection and combination of these modular structure formed into various products. These basic structure can be parts, components, or even a system. The ideal modular structure should be standardized interface (connectivity and with the Department of), and is serialized, universal, integrated, hierarchical, flexible, economic, with interchangeable, compatibility and relevance of the . China's combination of software component technology and CAD technology, design and composition of deformation design combined, according to grade modular theory, machine processing center will be divided into Youdadaoxiao product level, component level, component-level and component level, and use CAD technology and expertise to their portfolio into different species, different specifications of the functional module, the module from the combination of these functions into different processing center overall programme. To select a design for the directory structure of the variation machinery tools, the design of the proposed elements for a complete, structured format, a solution set design directory. And Set Design listed in the directory comment on each of the additional information, very beneficial to design engineers choice of the elements. According to the connectivity features of mechanical parts and components, will be summarized into four types: 1) The components of direct targeting, and self-adjustment of parts, 2) a common structure of the assembly, 3) have nested structure and inlay Shell-like components of the connection, 4) a modular architecture and modular components of the connection. And a quasi-symbols that the typical components and rules of the connection between the components, to achieve this connection between the components of the algorithm and the concept of visualization. In the mechanical system design, "features a" module on the functions of decomposition, and provides the best functional decomposition "tablets" of the extent of the functional and institutional forms of one-to-one. "Structure to establish" as a function of the module is the choice of targets in order to achieve mapping algorithm. 3, based on knowledge of product design features Knowledge-based product design features of the main features are: to use the computer to identify the language describing the characteristics of the product design experts in the field of knowledge and experience to establish the appropriate knowledge base and reasoning machine, and then use the storage areas have been established by the knowledge and reasoning Mechanisms to achieve computer-aided design products. The mechanical system design is based on products with the characteristics, and design experts in the field of knowledge and experience to push volume and decision-making, the completion of several comprehensive. To achieve this stage of the computer-aided design, we must study the automatic acquisition of knowledge, expression, integration, coordination, management and use. To this end, the scholars at home and abroad designed for mechanical systems design knowledge of automated processing done a lot of research work, the method used can be summarized in the following few. 3.1 coding method According to "campaign conversion" feature (the function million) institutions will be classified, described and use the code function yuan and institutional categories, which established a "body system design expert system" Knowledge Base. On this basis, will be the dual logic and fuzzy comprehensive evaluation of combining theory, the establishment of the "expert systems" reasoning mechanism, and for the four-position for the design of the machine. Use of biological evolution theory, through natural selection and sexual reproduction to the principle of evolution of organisms to the body design, use of network theory methods to express the structure for topology, and then through the coding technology, the structure and institutions Performance of individual chromosomes into the binary string, and in accordance with design requirements of fitness, the use of biological evolution theory of reproduction control mechanism, through the selection, crossover, such as a sudden variation means to eliminate low value of the individual are not suited to the fast evolution Be the best adaptation of the individual, that is, most with the design requirements of the agency programme. 3.2 knowledge of the law mixed The complex mechanical systems design, mixed use of the knowledge expression describes the design of various types of knowledge is particularly suited to this point has been the design of many scholars of the consensus. In the development of complex product design intelligent decision support system DMDSS, will be the rules, framework, processes and neural networks, and other knowledge that organic combination of methods to adapt to different types of knowledge in the design of the description. Knowledge will be a single expression of a variety of methods (rules, framework and process), according to object-oriented programming principles, the framework of the groove with that object's properties, with rules that target the dynamic characteristics, with the knowledge that the treatment process, group Into a hybrid form of knowledge, and successfully developed the "object-oriented NC gantry milling machine gearbox design intelligent system GBCDIS" and "transmission structure design expert system GBSDES". 3.3 use of the knowledge-based development tool Coupling in the CAD system, the use of the knowledge-based development tools NEXPERT-OBJECT, through the use of object-oriented approach, to create an object-oriented database design method for coupling the designer to design and structural design Provided extensive and reliable method of the design spectrum. NEXPERT describe the use of linear guide the design of the need to design based on knowledge of the content, which seek to knowledge-based solutions, and developed a linear guide design expert system. 3.4 Design Law Directory Construction of the "modules", "functional element solution" and "institutions" three progressive design directory, and this directory of three progressive design principles of the programme as a mechanical transmission system intelligent design and development of the knowledge base of design Aids. 3.5 Based on the example of the way In the development of expert systems design knowledge base, using the basic predicate described design requirements, design conditions and the selected programme, described by frame "Project" and various "concept entity," through case-based reasoning of the technologies used to produce candidate With the horsepower to product design requirements. 4, Intelligent Design Intelligent Design is the main characteristics: According to the theories of design, through the use of 3D graphics software, intelligent design software and virtual reality technology, and multimedia, hypermedia tools for product development design, the concept of products, description of the product. In the use of mathematical systems theory at the same time, consider the theory of systems engineering, product design technology and systems development methodology VDI2221, developed for use in the early design of multimedia software development system MUSE. Automatic teller machines in the design, the product of the entire development process summed up as "product planning" and "development" and "production planning" three stages, and made full use of existing CAD cutting-edge technology - virtual reality technology. 1) product planning - idea products. Its task is to identify the external characteristics of products, such as color, shape, surface quality, ergonomics and so on, and the initial idea of using 3D CAD model show, to establish the appearance of the product simple model, the model can be vir
