一种用夹具车削阀体内孔的工艺方法

A fixture for turning the valve hole processing method

对于小型阀体内孔的车削加工,通常会采用角铁式车夹具装夹加工,本文采用不同于通常的角铁式车夹具的方孔定位夹紧夹具装夹加工;同时,利用阀体零件自身的螺纹孔进行定位夹紧加工。二者结合,使得夹具制作简单,加工方便,阀体内孔精度要求更容易保证。

For small hole of a valve body turning,usually by angle iron type vehicle clamp clamping and processing,this paper adopts different angle type vehicle clamper square hole positioning clamping fixture clamping and processing;at the same time,use of body parts from the threaded holes of positioning and clamping for processing.The combination of the two has the advantages of simple manufacture,convenient processing,and easier precision of the inner holes of the requirements to guarantee.
