缸体加工工艺、夹具及气动系统设计大学毕设论文

摘 要零件的加工工艺编制，在机械加工中占有非常重要的地位，零件工艺编制得合不合理，这直接关系到零件最终能否达到质量要求；夹具的设计也是不可缺少的一部分，它关系到能否提高其加工效率的问题。因此这两者在机械加工行业中是至关重要的环节。本次设计的是压缩机箱体加工工艺以及夹具的设计，压缩机主要作用是把低压气体吸进压缩成高压气体----冷却循环，使部分动能转化为压力能从而提高气体的压力。压缩机箱体则是承载这个压力和连接各零部件，因此要求箱体能够承受压力，以及箱体与其他零部件的密封性，在编制加工工艺时，要考虑到各个接触面的各项精度以及形状与位置公差等。本次设计需要设计两套夹具，一套是车床专用夹具，一套是钻床钻床夹具。关键词：工艺 基准 切削用量 定位基准 夹具ABSTRACTDesigning that originally time is that the compression engine box experiences and observes the design processing handicraft and the clamp , the main effect of compression engine is that the cryogen vapor body inhales the high-handed vapor compressing Cheng in experiences and observes——the circulation cooling down , makes part kinetic energy change the pressure being that pressure can improve the vapor body thereby with low pressure. Then, the compression engine box body is to bear the weight of this pressure and links every component and part, Require that the box body is able to bear pressure therefore, and box body comparing with other component and part hermetic sealing, before work out when processing handicraft , ask accuracy and form and location common difference etc. to consider various arriving at each contact surfaces.The design requires two sets of fixture design, one is a fixture for lathes, and the other is a fixture for Driller.Key words: Technology benchmarks cutting the amount location benchmark Fixture目 录摘 要...................................................................................................................................
