铰珩工艺在汽车转向器阀套中的应用研究

针对传统珩磨工艺在汽车转向器阀套加工中存在的精度不足和效率不高问题,引入一种单冲程超硬磨料珩磨孔加工技术,即铰珩工艺.根据阀套的加工特点,设计相应的夹具和刀具方案,并通过正交试验法研究铰珩工艺参数对加工性能的影响.参数经过优化的铰珩工艺,有效解决了阀套内孔加工的精度问题,取消了配磨工序,提高了加工效率.

Application of Reaming Honing Technology in Valve Sleeve of Automobile Steering Gear

A single-pass honing technology with super hard abrasive,named reaming honing technology,is used to solve the low accuracy and efficiency caused by the traditional honing technology which is used to machine the valve sleeve of automobile steering gear.The fixture and cutter proposal is given according to the machining characters of the valve sleeve,and the orthogonal test is used to investigate the effects of the reaming honing parameters on the machining performance.The reaming honing technology with the optimized parameters proves itself to solve the accuracy problem in the machining of valve sleeve effectively,as a result the match grinding processing is cancelled and the machining efficiency is improved.
