邵陽學院畢業(yè)設(shè)計 論文 內(nèi)容提要 目前 在機械加工工業(yè)中 機械產(chǎn)品大批量生產(chǎn)中 組合機床已得到廣泛運 用 一些復雜的殼體類零件 加工工藝復雜 定位夾緊困難的工件 要提高其加 工精度 生產(chǎn)效率 單憑普通機床是很難辦到的 而在用普通機床加工復雜工件 的過程中 對操作者的技術(shù)也提了較高的要求 這就迫切的要求生產(chǎn)一定數(shù)量的 組合機床 這樣 不但可以提高零件的加工精度和生產(chǎn)率 而且成本低 生產(chǎn)周 期斷 適合我國的經(jīng)濟水平 教育水平和生產(chǎn)水平 更能夠在激烈的競爭中為企 業(yè)獲得更多利潤 提高企業(yè)核心競爭力 雙向臥式組合鏜床設(shè)計主要包括臥式單工位雙面組合鏜床傳動系統(tǒng)圖的設(shè)計 和多軸箱設(shè)計 夾具 刀具導向裝置的設(shè)計和夾緊裝置的選擇 臥式單工位雙面 組合鏜床傳動系統(tǒng)圖的設(shè)計和多軸箱設(shè)計 夾具 刀具導向裝置的設(shè)計和夾緊裝 置的選擇是組合機床的主要組成部分 是保證加工精度的關(guān)鍵部件 它和機床的 其它部分有著及其密切的聯(lián)系 因此 要求組合機床必須具有良好的剛性和足夠 的夾緊力 以保證在整個加工過程中工件不產(chǎn)生位移 同時 保證工件加工的各 項技術(shù)要求 要保證工件不允許的變形 提高生產(chǎn)率和降低生產(chǎn)成本 工藝性和 實用性要好 根據(jù)加工零件的加工特點 選擇一面兩孔作為定位基準 所以采用 一面兩 孔 銷的定位方法清除工件在加工時的六個自由度 為了確保定位精度和穩(wěn)定 性 采用三個固定支承和一個一點自動定位輔助支承 定位銷采用液壓驅(qū)動伸縮 式定位銷 液壓驅(qū)動伸縮式定位銷采用帶防護罩的 用支承板定位系統(tǒng) 它用油 缸經(jīng)過推桿和一系列杠桿實現(xiàn)定位銷的插入和拔出 邵陽學院畢業(yè)設(shè)計 論文 Summary Currently in the machining industry mechanical products for mass production modular machine tool has been widely used Shell complex parts machining complex positioning of the workpiece clamping difficult to improve the processing accuracy efficiency ordinary machine alone is a difficult task and in general with complex workpiece machining process in the operation of the technology has raised higher demands which urgently request the production of a certain number of combinations machine This will not only improve the machining precision components and productivity and low cost production cycle broken suitable for China s economic level education level and the level of production More to the fierce competition for enterprises to get more profits and enhance core competitiveness Two way combination of horizontal boring machine design include horizontal single boring machine duplex transmission combination of the design plans and multi axle box design Fixture tool oriented design and installation of the clamping device choice Horizontal single boring machine duplex transmission combination of design plans and multi axle box design fixture Tool oriented design and installation of the clamping device choice is the combination of machine tools major components guarantee the accuracy of the processing of key components It and other parts of the machine tool and has close ties Therefore the request must portfolio machine has good rigidity and sufficient clamping force to ensure that the entire workpiece machining process does not produce displacement Meanwhile to ensure the workpiece machining technical requirements and to ensure that the deformation of the workpiece impermissible improve productivity and reduce production costs technology and practical better According to the workpiece on the processing characteristics of a two choice positioning as a benchmark Therefore a two hole marketing 邵陽學院畢業(yè)設(shè)計 論文 methods to remove the positioning of the workpiece machining of six degrees of freedom To ensure positioning accuracy and stability using three fixed bearing and an automatic positioning 1 00 auxiliary support pin using telescopic hydraulic drive pin Hydraulic telescopic pin used with protective masks using bearing plates positioning system Using tanks and after putting a series of levers to achieve pin inserted and the pull out
