摘 要
泵依靠旋轉(zhuǎn)葉輪對(duì)液體的作用把原動(dòng)機(jī)的機(jī)械能傳遞給液體。由于泵的作用液體從葉輪進(jìn)口流向出口的過(guò)程中，其速度能和壓力能都得到增加，被葉輪排出的液體經(jīng)過(guò)壓出室，大部分速度能轉(zhuǎn)換成壓力能，然后沿排出管路輸送出去，這時(shí)，葉輪進(jìn)口處因液體的排出而形成真空或低壓，吸水池中的液體在液面壓力（大氣壓）的作用下，被壓入葉輪的進(jìn)口，于是，旋轉(zhuǎn)著的葉輪就連續(xù)不斷地吸入和排出液體。
本次設(shè)計(jì)了泵體工藝規(guī)程及鉆孔夾具的基本過(guò)程，包括五章：第一章，緒論；第二章，工藝設(shè)計(jì)；第三章，工序設(shè)計(jì)；第四章，夾具設(shè)計(jì)；第五章，設(shè)計(jì)總結(jié)。
以便清楚明了表達(dá)泵體在生產(chǎn)中的應(yīng)用、機(jī)械加工工藝過(guò)程及機(jī)床夾具設(shè)計(jì)的基本步驟，文中插入了相關(guān)表格和簡(jiǎn)圖，詳細(xì)敘述了泵體加工定位基準(zhǔn)面、工序尺寸的計(jì)算過(guò)程，夾具元件設(shè)計(jì)等。
關(guān)鍵詞：毛坯余量、工藝、工序、切削用量、夾具、定位、誤差。
ABSTRCT
The pump depends the effect which revolving impeller works on liquid in transferring mechanical energy to liquid. Owing to pump, when the liquid flow out of the impeller, its speed energy and stress energy both develop much, the liquid debarred by the impeller , most speed energy is transferred to stress energy ,and then it is transported through pipeline .At this moment ,the entry of the impeller become vacuum or low-pressure , hydraulic pressure (pneumatic pressure ) effect on the liquid in the absorbing pool, and the liquid is pulled into the entry of the impeller , so ,the rotating impeller continuous inhalants and Drainage liquid.
This time has designed the pump body's processing craft and the pump design unit process which including five chapters, first chapter, exordium; The second chapter, technics design; The third chapter, working procedure design; The fourth chapter,jig design and the last chapter,design conclusion.
In order to understand clearly expresses the pump in production application, machine-finishing technological process and the engine bed jig design basic step, in the article has inserted the related form and the diagram, narrated the pump to process the localization reduced plane, the working procedure size computational process in detail, the jig cell design and so on.
Keywords: rough allowance, working procedure, techniques, cutting dosage, jig allocation, error
