工藝夾具類我的畢業(yè)論文的題目是發(fā)動機箱體的機械加工工藝規(guī)程和專用夾具設(shè)計。發(fā)動機箱體是機器的基本零件，它將機器和發(fā)動機中的軸、套、齒輪等有關(guān)零件連接成為一個整體，并使之保證正確的位置以傳遞轉(zhuǎn)矩或改變轉(zhuǎn)速來完成規(guī)定的運動。發(fā)動機箱體的加工質(zhì)量直接影響機器的性能、精度和壽命。
本設(shè)計說明書是根據(jù)機械制造工藝專業(yè)教學委員會所制定的教學計劃和教學大綱，結(jié)合所學專業(yè)的理論和實踐知識，編寫設(shè)計處一套機械加工工藝規(guī)程和工裝夾具。本此設(shè)計有工作量大、專業(yè)知識范圍廣、要求高等特點，不同于前面所做的課程設(shè)計。對我們畢業(yè)生來講，是對我們所學專業(yè)知識的一次重大考驗，也是對我們參加工作之前的很好的歷練。既提高了我們的專業(yè)要求，又培養(yǎng)了我們的實際設(shè)計意識。
說明書對零件的功用分析、零件的加工工藝過程、夾具工藝設(shè)計作了比較系統(tǒng)、完整的分析和論證。對工藝規(guī)程的設(shè)計作了詳細的說明，并制定了合理的加工工藝路線。對關(guān)鍵工序的加工余量、工序尺寸、工序公差、切削用量進行了設(shè)計分析，保證整個工藝過程的完整。最后，對夾具精度也進行了校核計算。

關(guān)鍵詞：發(fā)動機箱體；機械加工工藝；夾具；工序；加工余量；工序尺寸；切削用量；夾具精度

Abstract
The topic of my thesis is the design of machining technics regulatious and appropriative clamp of the box body of engine .The box of engine is the basic spare of machine,it conecs the staik,set,wheel gear…etc of engine to the whole.And accurate position to transfer torque or complete prescriptive movement.The machining quality of the box body of engine will influence the performance,precision an life of machine.
According to the plan and didactical brief made by machine manufacturing craft profession committee,this design have mainly compiled and designed teachining technics regulations and appropriative clamp using professional theory and practical knowledge.This design is not only a great chanllenge,but also a good exercise for our graduate.It has enhanced our lever of speciality,at the same time,it also has cultived our team sprint.
The design mainly introduces the spare parts craft process,tongs technological design to make comparison system,analysis and argumen integrity.Design craft regulations to make expation,and establishment reasonable of process craft route.In this design,I have analysed and calculated some key working proces,which include the remaining quantity of process,the measure of working procedure procedure the tolerance of working procedure techics cards.Whatmore in the end ,I have designed a appropriative clamp and proof-tested its precision to ensure the quality of workpiece.

Keyword:machining quality;the techics of machining;clamp;working procedure;the remaining quantity of maching;the measure of working procedure;precision
