摘　　要：对空压机曲轴在机械加工中产生定位误差的原因进行了分析,并在此基础上设计了一种用于曲轴机加工夹具的浮动V形块。对浮动V形块的结构进行了介绍,并对夹具采用浮动V形块后的曲轴机械加工定位误差进行了分析,确认采用浮动V形块后满足定位要求,可以提高工件的加工质量。The causes of the positioning error of the air compressor crankshaft in machining were analyzed. Based on this, a floating V-shaped block used in the fixture for machining of the crankshaft was designed. The structure of the floating V-shaped block was introduced. The positioning error in machining of the crankshaft after use of the floating V-shaped block was analyzed. It is confirmed that the floating V-shaped block can meet the positioning requirements and the machining quality of the workpiece can be improved.
