外圆磨床在大量成批磨削加工有凸台阶轴的端面时,为了保证凸台阶轴向距离的精度要求,往往需要多次停机测量,不但劳动繁锁,影响加工速度,而且也较难控制精度。现在为了解决这一问题,我们设计了一种“磨削主动测距仪”,其结构简单,测量方便,精度也较可靠,它的工作原理与结构如图所示。基准臂1种活动臂4的头部各装一根测头 Cylindrical grinding machine in a large number of grinding process has a convex step axis of the end face, in order to ensure the convex step level axial distance accuracy requirements, often require multiple downtime measurement, not only complicated, affecting the processing speed, but also more difficult to control Accuracy. Now in order to solve this problem, we designed a “grinding active range finder”, its simple structure, easy measurement, accuracy and more reliable, its working principle and structure shown in the figure.
