Fixture for end-tooth flange york boring lug hole and vehicle clamp spring groove and machining technology achieved by means of fixture

The invention discloses a fixture for an end-tooth flange york boring lug hole and a vehicle clamp spring groove and a machining technology achieved by means of the fixture. The fixture comprises a fixture body, a positioning disc and a hydraulic clamping mechanism; the machining technology comprises the step that the machining procedures of the end-tooth flange york boring lug hole and the vehicle clamp spring groove are both positioned through end face teeth arranged on the bottom face of an end-tooth flange york and end face teeth of the fixture positioning disc. Accordingly, in the machining process of the end-tooth flange york lug hole of a transmission shaft, two original tedious positioning steps are reduced into one precise positioning process, two machining machine tools are reduced into one machine tool, therefore, the production efficiency is improved, and the production cost is reduced. 本发明公开了种传动轴端齿突缘叉镗耳孔、车卡簧槽用夹具及其加工工艺，夹具包括夹具本体、定位盘和液压夹紧机构，所述加工工艺为端齿突缘叉的镗耳孔与车卡簧槽加工流程均通过端齿突缘叉底面的端面齿与夹具定位盘的端面齿定位。本发明在进行传
