变径轴颈套筒前后内孔加工

Working for Front and Rear Inner Hole of Sleeve with Varied Diameter Shaft Neck

变径轴颈套筒远距离内孔要求保证其同轴度,在机加工过程中根据其结构特点设计专用工装——镗模。用镗模装夹该零件进行加工,确保其装夹简化,操作简便,降低加工难度并能保证其精度满足套筒孔同轴度的要求。

This paper introduced that the technological key task in the processing of mechanical working within a distance for the coaxality of the front and rear inner hole the sleeve with varied diameter shaft neck should be ensured - the module in the boring ma- chine fixture was designed according to the construction feature of the sleeve. This module fixture for working the sleeve is to be used, simplify the working processing, easy to operate and reduce the working difficulties could be realized, and the precision could be en- sured and requirement of the coaxality of sleeve could be satisfied also.
