南昌航空大学科技本科生毕业设计 加工刀架座工装设计 摘 要 摘要: 在机械产品制造中，机械加工工艺规程和机床夹具起着十分重要的作用，零件的加工质量与零件的加工工艺、正确的定位及机床夹具有着直接的关系。合理的工艺规程设计及夹具设计对于保证零件的加工精度，缩短辅助时间，提高劳动生产率，降低生产成本，及减轻加工工人的劳动强度和降低对工人的技术要求有着十分重要的意义。 本文主要讲述了加工变速箱箱体工艺过程的设计及铣、镗两道工序机床专用夹具的设计.首先对该零件的作用及结构工艺进行了全面的分析,在此基础上制定加工工艺路线,确定最佳设计方案.其次对加工过程中的切削用量及基本工时做了详尽的计算.最后对机床专用夹具进行设计,并校核,确保夹紧可靠,可安全工作.关键词： 加工工艺、机床夹具、设计Abstract: In machinery production , the machinery manufacturing instruction and the fixture of machine tools have got the prominent action in machinery production. The reasonable and reliable of its design can prone to achieve the accuracy of parts processes, shorten lend support time, increase the labor rate of production, diminish the production cost; and also can alleviate the workers operating strength, lower the request of the workers technique. The text primarily tells the manufacturing processes of the gearbox, and the two special fixtures design of milling、boring processes. First make completely analysis to the parts function and construction. On the basis of this, make the process route, and use the optimum arrangement. Next make calculation in details of cutting engagement and basis man-hours in the process. Finally, do the fixtures design, combining proofread, and make sure the chuck dependable, the work safety.Keywords: nontra
