摘要 这篇设计的知识面是比较多的，有机械加工工艺，有设计机床夹具，还有金属切削加工机床，公差配合跟测量等等。 支承套零件的加工工艺分析及其钻孔夹具设计是包括零件加工的工艺设计、工序设计以及专用夹具的设计三部分。设计工艺的时候，一开始分析零件，要知道它的具体工艺，之后才能将毛坯的构造设计出来，之后确定产品的加工工艺，将加工产品的工艺路线写出来；之后将产品每一个工序的大小算出来，主要就是在于每一道工序用什么工具，还有切削加工量是多少；之后设计专用夹具，将夹具每一个部分的零部件设计出来，比方说定位零件，夹紧零件等等；在用夹具对产品进行定位时候会有偏差，对于夹具构造哪些地方好，哪些地方不好都分析出来，之后对他进行修正。 关键词：支承套；加工工艺；钻孔；专用夹具；夹具体 Abstract There are ma
