支柱孔滚子加工工艺及工装的改进

Improvement on processing technology and tooling of pillar hole roller

针对支柱孔滚子加工难度大的问题,对工艺进行了改进,利用齿轮顶尖,确保支柱孔滚子的同轴度;利用双刃镗刀,确保支柱孔的粗糙度,解决了直径95mm以上、长度140mm以上支柱孔滚子加工的瓶颈问题。并且提高了产品的加工质量。

In order to solve the difficult problem of pillar hole roller in processing, the technology was improved by using top gear to ensure the coaxiality of pillar hole roller, and using double -edge boring cutter to get appropriate roughness of pillar hole. It solved the bottleneck problem of roller with diameter of more than 95mm and length of more than 140mm. The procesing quality of product was also improved.
