1、 I 摘要摘要 连杆是汽车空压机的主要零件，形状复杂，刚度差，容易变形，精度要求高，加 工比较困难，因此对机床和刀具都有特殊的要求。连杆的尺寸精度、形状精度以及位置 精度的要求都很高，而连杆的刚性比较差，容易产生变形，因此在安排工艺过程时，就 需要把各主要表面的加工工序分开。本文章主要设计了连杆的加工工艺和夹具设计。 关键词关键词: : 连杆、连杆、加工工艺、夹具加工工艺、夹具 II Abstract The connecting rod is the main parts, shape complicacy of the air compressor, just the degree is
2、bad, and the strain, accuracy request high, process the comparison difficulty, and request engine bed and tool angel had specially. Rod dimensional accuracy, shape accuracy and position accuracy requirement are high, and the connecting rod rigidity is relatively poor, prone to distortion in the arrangement process, you need to separate the main surface of the rough finishing operations. This paper mainly discusses the linkage of process and fixture design. Keywords：connecting 、process、fixture. III 目录目录 摘摘 要要. .I Abstract.
