CX3活塞环外圆形线自动检测仪

CX3 Auto-detector for the External Dimensions of the Piston Ring

针对汽车行业检测设备的陈旧落后，阐述了活塞环自动检测仪的功能和用途及工作原理，介绍了测力的自动控制，用工作脉冲“调制”的方法驱动步进电机，系统硬件构成，接口设计以及软件系统功能和设计方法。

This paper first describes the functions, the principle of operation,and the ap-plications of auto-detector for the piston ring. It then introduces the micro-computer con-trol of contact force and the step motor driving by the method of the pulse width modulation.Finally,the functions and design method of system,hardware,interface,and software are alsodescribed.
