随着国家对汽车行业的调整，汽车已经成为国民经济支柱产业。汽车零部件之一的活塞环需求量日益增大，活塞环的检测方法尤为重要，特别是一些大型货车、工程车辆造价相当高，为了节约资源，本着降低成本的目的，活塞环的检验方法就非常重要。我国现在许多检测方法并不成熟，需要进一步的改进。同时作为毕业时设计的课题，强化了实际操作的能力。

 

 

 

Abstract

With the national adjustment of the automotive industry, the car has become a pillar industry of the national economy. One of the auto parts of the piston ring is increasing demand, the piston ring detection method is particularly important, especially some large trucks, engineering vehicles cost is very high, in order to save resources, in the purpose of reducing costs, the piston ring test method It is very important. China now many detection methods are not mature, need further improvement. At the same time as a graduate design of the subject, to strengthen the practical operation of the ability.

This set of piston test instrument mainly by the test plate, test platform, sales control positioning rods, lifting blocks and dial indicator composition. The main items of this measurement include the piston ring crossbar, piston ring diameter, piston pin hole center line and the bottom of the parallelism, connecting rod bending and twisting.

 

Key words: piston detector; test platform; measurement
