万向节滑动叉的加工工艺规程及车削Ф62右端面夹具设计
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。
滑动叉加工工艺规程及其车削Ф62右端面的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。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、引导元件等。通过绘图软件完成夹具装配图及夹具体零件图的绘制。
关键词:夹具设计、滑动叉、加工工艺、车削、Ф62右端面
