液压制动装置杠杆臂的新型加工工艺设计及验证

New Processing Technology and Verification of Hydraulic Braking Device Lever Arm

液压制动装置中的杠杆臂组装件由杠杆臂和转动轴组成。液压制动装置试验中杠杆臂与转动轴转动出现咬合现象,是由于液压制动装置杠杆臂为异形件、深孔且形位公差高,加工存在困难。通过杠杆臂新型加工工艺设计,保证了杠杆臂组装的装配精度,为同类零件加工工艺的设计提供了借鉴参考。

The lever arm assembly in the hydraulic brake device is composed of a lever arm and a rotating shaft.In the test of hydraulic braking device,the lever arm and the rotating shaft appear to OCCLUSAL phenomenon.Because the lever arm of hydraulic braking device is abnormity part,deep hole and high tolerance of shape and position,it is difficult to process.The assembly precision of lever arm is ensured by the new process design,which provides a reference for the design of similar parts.
