摘　　要：液压制动装置的中间缸体组装件主要由中间缸体、碟簧、缓解活塞组成。由于中间缸体是薄壁件,且具有极高的同轴度公差导致该零件加工难度增加,因而出现产品成批报废现象。通过改进中间缸体的加工工艺,确保中间缸体加工零件的同轴度公差符合设计要求,为制订同类型的零件加工工艺提供一定的参考。The intermediate cylinder block assembly of the hydraulic braking device is mainly composed of the intermediate cylinder block,the disc spring and the relief piston.Because of the thin wall and high coaxiality tolerance of the middle cylinder block,it is more difficult to process the parts,so the products are scrapped in batches.By improving the machining process,the coaxiality tolerance of the processed parts of the intermediate cylinder block is ensured to meet the design requirements,which provides a certain reference for formulating the machining process of the same type parts.
