活塞是发动机的重要零件之一.活塞的各部位不仅有较高精度的尺寸公差要求,还有较多的形位公差要求.仅对活塞矩形环槽,笔者就接触过多种形位公差标注方式.通过检测仪器,如何正确无误地得出原设计所要求的形位公差检测结果,是本文阐述的主要问题.1 环槽形位公差标注方式实例我厂自1985年至今已进行了多达几十种活塞新产品试制工作,因为引用的标准不同,活塞环槽的形位公差要求主要有以下几种:
Piston is one of the important parts of the engine.All the parts of the piston not only have high dimensional tolerance requirements, but also more geometric tolerances.Only the piston rectangular groove, I have contact with a variety of geometric tolerances Way through the testing equipment, how to correctly draw the original design requirements of the form of tolerance test results is the main problem described in this article.1 ring groove bit tolerance example of the way I have been factory since 1985, up to Dozens of Pistons new product trial work, because of the different standards, piston ring groove form tolerance requirements are the following:
