前言活塞环为汽车发动机中的一个零件,需要量大,精度要求高(厚度公差为0.012mm),必须百分之百的测量。过去靠人用千分尺转圈测量,劳动强度大,生产效率低,直接影响汽车产量的提高。为了改变这一状况,中心计量室部分同志设计制造了轧辊式活塞环厚度检验机。经过一段时期的试用,初步证明该机精度较高,测量可靠,调试维修比较方便,效率 Preface Piston Rings is a part of a car engine that requires a large amount of precision and high accuracy (thickness tolerance of 0.012mm) and must be 100% measured. In the past by people with a micrometer circle measurement, labor-intensive, low productivity, a direct impact on the improvement of automobile production. In order to change this situation, part of the central measurement chamber design and manufacture of roll gauge piston ring thickness testing machine. After a period of trial, preliminary proof of the aircraft higher accuracy, reliable measurement, commissioning and maintenance more convenient, efficient
