活塞内圆表面光整加工工艺探讨

The Research and Discussion on the Measures to Improve Polishing Process Quality of Inner Hole of the Piston

以活塞内孔加工为研究对象,针对圆孔光整加工工艺中存在的缺憾,分析了圆孔拉削工艺的优势与目前存在的问题,并通过专用圆孔拉刀结构改进试验的对比,提出了一专用圆孔拉刀和拉削光整加工相关参数确定的计算方法.实验对比分析表明:该方法能够提高圆孔表面精度质量,减小表面粗糙度.

This paper has studied on processing of inner hole of the piston. In view of the defect during the polishing process of hole, the author has analyzed the superiority and problems of broaching process of the hole with a series of experiments and data. Through the contrast on improvement test on structure of broach of the hole, this paper has demonstrated the resolution to improve polishing process quality of the hole. Additionally, this paper has introduced a modified broach and a calculating method of the broaching and polishing process which has definite parameter. In order to improve the precision of surface of the hole and reduce the surface roughness, this paper has put forward practical measures and methods.
