摘要
对汽车同步器齿套齿端倒尖角进行了几何分析,建立了仿真模型。开发出了可进行参数化设计的计算机软件,利用计算机仿真的方法确定出倒角成型刀的参数和加工时的刀具调整参数,节约了人工调刀时间,使齿端倒尖角理论加工精度从原来的±5°提高到±1°。在得到仿真结果的基础上进行了加工精度影响因素的分析,提出了减小加工误差的建议。
Geometric analysis of chamfering sharp angle on the end face of the vehicle synchronizer sleeve is carrid out,and its simulating model is created.The parametrization software is developed.Developing parameters of the chamfer mold ing cut ter and tool adjusting parameters on machining with computer simulation methods can save cutting tool adjust-ing time and can improve the theory machining precision from±5to±1.Based on simulating results,factors affecting ma-chining pre cision are analyzed,and proposals on reducing machining errors are presented.
