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CQM6132主轴前轴承的加工工艺以及夹具的设计,CQM6132车床主轴前轴承是滑动主轴,滑动轴承的承载能力大,回转精度高,润滑油膜具有抗冲击作用,那么在加工轴承的时候就有很高的加工工艺要求,因此在编制加工工艺时,要考虑到轴承的各项精度以及形状与位置公差等。
在设计加工内锥孔的专用夹具时,为了为使加工简便且易实现,可采用一靠模(该靠模槽的倾斜度刚好等于工件被加工面的1:20锥度)来完成。这样不仅能满足加工要求,更可以一次性走刀完成加工 ,大大提高了加工效率。
关键词:工艺设计、切削用量、夹具设计、定位基准、定位误差。
