Rod dimensional accuracy, shape accuracy and position accuracy requirement are high, and the connecting rod rigidity isrelatively poor, prone todistortion inthe arrangement process, you need toseparate the main surface ofthe rough finishing operations. This paper mainly discusses the linkage ofprocess and fixture design. Keywords :connecting 、process 、fixture. 湖北汽车工业学院毕业(设计) 论文 IV 目录摘要………………………………………………………………………………………..
