提高轮毂同轴度和垂直度的工艺研究

Study on Technology of Improving Hub Coaxiality and Verticality

针对某型号轮毂同轴度和垂直度超差问题,对原加工工艺进行优化,分析影响同轴度和垂直度超差的主要因素。通过设计精车专用工装、合理选用精车刀具和优化工序等保证了轮毂同轴度和垂直度的加工精度,使产品合格率提升至96%,并提高了装夹找正效率,解决了困扰企业生产的技术难题,可为类似产品加工提供一定借鉴。

The original processing technology is optimized for the problem of excessive coaxiality and verticality of a certain type of wheel hub,and the main factors of affecting excessive coaxiality and perpendicularity are analyzed.The processing accuracy of wheel hub coaxiality and verticality is guaranteed by designing special tooling for precision turning,selecting reasonably finish tools and optimizing processes,etc.,so that the product qualification rate is raised to 96%,and alignment efficiency of the clamping is improved.The technical problems plaguing enterprise production are solved,and can provide some reference for the processing of similar products.
