摘要 我设计题目为接合器架加工工艺设计及加工M8孔专用夹具设计，本零件为3659型半自动钻头磨床接合器架是用来支承接合器。从所给的接合器架零件知，零件Φ32孔、Φ55外圆、Φ126左端面、宽14环形槽、宽22槽和Φ6孔，是整个接合器架零件精度最高的地方，也是接合器架与接合器连接的部分。 接合器架的加工工艺设计，首先分析接合器架结构特点，接合器架为回转类零件，而回转类零件一般以外圆作为定位粗基准来加工精基准，再以精基准定位加工余下面各面和孔等，整理编写成工艺过程卡，由参考文献[1]查找各个加工表面的加工余量，绘制接合器架毛坯图，工序卡图，最后对各工序切削参数进行选择和计算。 接合器架加工M8孔专用夹具设计，夹具设计总体上包括三方向面，现分述如下：①定位机构，确定元件和定位方案的依据为六点定位原理。②夹紧机构，夹紧机构大体上可以分为手动夹紧，机构夹紧和电磁夹紧。而本设计采用的用手动夹紧。③辅助机构，比如车床的配重块，铣床的对刀块或钻床的钻套等。 关键词：接合器架；工艺分析；专用夹具设计 Abstract My desig
