轴套零件的铣2-5mm槽夹具设计及加工工艺规程装备 摘要 本次设计内容涉及了机械制造工艺及机床夹具设计、金属切削机床、公差配合与测量等多方面的知识。 轴套的加工工艺规程及其铣两个宽5槽的工装夹具设计，包括零件加工的工艺设计、工序设计以及专用夹具设计三部分。在工艺设计中要首先对零件进行分析，了解零件的工艺再设计出毛坯的结构，并选择好零件的加工基准，设计出零件的工艺路线；接着对零件各个工步的工序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量；然后进行专用夹具的设计，选择设计出夹具的各个组成部件，如定位元件、夹紧元件、引导元件、夹具体与机床的连接部件以及其它部件；计算出夹具定位时产生的定位误差，分析夹具结构的合理性与不足之处，并在以后设计中注意改进。 关键词：轴套,加工工艺,铣两个宽5槽,夹具设计 Abstract The desig
