中英文摘要
這次畢業(yè)設(shè)計(jì)我設(shè)計(jì)的課題是PM400減速器箱體加工工藝及組合鏜床夾具設(shè)計(jì)。該箱體零件結(jié)構(gòu)復(fù)雜，體積大。為了提高生產(chǎn)效率和降低勞動(dòng)強(qiáng)度，專門設(shè)計(jì)一精鏜三主軸軸承孔的組合鏜床及其專用夾具。本設(shè)計(jì)說明書可分為四部分：
第一部分為機(jī)械加工工藝規(guī)程的編制，簡要的分析了零件作用及其工藝情況對(duì)毛坯的制造、加工基準(zhǔn)進(jìn)行選擇并制定工藝路線，確定機(jī)械加工余量，工序尺寸及切削用量等。
第二部分為組合鏜床設(shè)計(jì)。設(shè)計(jì)的機(jī)床是單位組合機(jī)床進(jìn)行單面加工。從工件定位及夾緊可靠，保證加工精度出發(fā)，選擇臥式單面非剛性軸組合鏜床。并繪制了加工工序圖，加工示意圖和臥式單面組合鏜床的尺寸聯(lián)系圖。
第三部分為專用夾具設(shè)計(jì)。夾具設(shè)計(jì)是本次設(shè)計(jì)的主要內(nèi)容之一。在設(shè)計(jì)中需對(duì)夾具的誤差進(jìn)行分析，還要對(duì)夾緊力進(jìn)行計(jì)算，以保證滿足加工要求。
最后是翻譯科技外文和編寫說明書。

關(guān)鍵詞：箱體 加工工藝 精鏜主軸孔 夾具

Summary
I graduated from this design is the subject of design modifications PM400 reducer combination boring lathe and machining jig design. Replace parts of the complex structure and size. To increase production efficiency and reduce labor intensity, specially designed one-precision combination of smooth-bore three main bearings Kong and dedicated jig boring lathe. The design specification can be divided into four parts : The first part of the preparation for mechanical machining, summary and analysis of the role of crafts for blank parts manufacture, processing options and to develop processes for the base line, identifying machinery allowance, size and cutting processes consumption. The second part was the design portfolio boring lathe. The machine tools are designed for paper processing unit combination machine tools. From her position and Jiajin reliable guarantee starting precision processing, printing of non-rigid axle portfolio choice horizontal boring lathe. And the mapping of the manufacturing processes, and processing paper maps and horizontal linkages portfolio boring lathe size chart. Part dedicated jig into the design. Jig design is one of the main elements of this design. In the design of the jig to the error analysis, but also for calculating Jiajin power to ensure that meet processing requirements. Finally, foreign language translation technology and the preparation of brochures. Keyword : replace machining precision smooth-bore main Kong jig.
