钻机分度盘的制造工艺及夹具设计 [摘要]分度盘制造工艺及夹具设计在机械制造中占有十分重要的地位。传统的机床使用的分度盘制造工艺及夹具设计存在工作强度大，而且操作维护也不方便，这给生产带来很大的困难，特别是增加了工人的工作强度，而且需要花费大量时间，在分度盘制造工艺及夹具设计不够紧凑的情况下，生产的产品品质就大打折扣，这会使得生产的成本增加了很多，同时也影响了公司企业或工厂的效益和名誉，生产效率也会降低很多，所以着手设计全新的分度盘制造工艺及夹具设计装置是一定要进行的。 本课题研究的是一种全新的分度盘制造工艺及夹具设计设计，不仅降低了引进设备的成本，还可以大大提高生产的精度和生产效率，此外本设计的分度盘制造工艺及夹具设计结构简单、工作性能十分可靠，同时也降低了工人的工作强度，所以分度盘加工工艺及夹具设计设计与制造将会产生很大的市场效益，具有十分良好的经济效益和可行性。而这次设计实现了所学理论与生产实践相结合，让我具有了制定工艺规程的能力，设计专用夹具的能力，进一步提高了查阅资料的能力，熟练地使用设计手册参考资料的能力。 [关键词]工艺；工序；夹具；定位；夹紧 Ma
