换向器滚压加工过程监测系统

根据换向器滚压加工成形的要求,提出选用电涡流传感方法对换向器成形的接触间隙进行检测,同时利用压电测力方法主动检测成形过程力的变化,将两种信息融和,构成检测系统.研究了位移传感器输出与被测间隙宽度、深度等之间的规律、电压限幅问题以及试件边缘翘曲的影响.通过压电测力仪同步测量加工过程力的变化规律,分析了夹具轴状况、压轮位置、接触间隙对力信号的影响,并进行了实验验证,弥补了单一信号的不足,提高了检测系统的准确性和可靠性.

Monitoring System for Commutator Rolling Process

According to the requirements of commutator rolling machining forming,the eddy current sensing method was put forward to detect the contact gap of commutator during forming process,and the piezoelectric force sensing measurement was used to detect the force change.Two kinds of information were fused to constitute the detection system.This paper studied the law between displacement sensor output and the measured gap width/depth,the voltage limiting issue and warping of the specimen edge.Piezoelectric dynamom...
