摘　　要：对活塞形位公差测量应用中的关键技术进行深入研究,分析活塞加工和检测过程中的关键误差,提出活塞形位误差的测量方法;设计活塞形位误差检测装置,提高测量的精度;搭建实验台对活塞圆度、圆柱度、对称度误差进行测量实验,为解决厂方打标变形问题提供理论上的依据。This paper intensively studied the key technology in the measurement of piston shape and position tolerance.Firstly,the paper analyzed the critical error in the process of piston machining and detection,and proposed a measurement method on piston position error（PPE）.In addition,a detection device of PPE has been designed,which improves the measurement accuracy.Finally,an experimental platform has been built to measure the roundness,cylindricity and symmetry error of piston.This method provides a theoretical basis for solving the problem of marking deformation.
