Choose the correct processing methods, design the reasonable process. In addition to the stuffing box cover part two process designing special fixture. This paper mainly onone side and 170 holes on the left crankcase parts as much as possible a process in place, design the special fixture design of drill hole. The two side pin positioning, manual screw clamping way, after verification, stable and reliable, and can be applied in practice. Key words: processing technology, processing method, process documentation, fixture 优秀机械毕业设计欢迎下载, 学****交流加 QQ 197216396 专业机械设计解君之忧 4 目录摘要......................................................................................................................................... 3 Abstract ....................................................................................................................................... 4 目录......................................................................................................................................... 5 第1章绪论............................................................................................................................... 1 机械加工工艺概述...................................................................................................... 1 机械加工工艺流程....................................................................................................... 1 1
