一、百分表测量法 用百分表测量某立式车床工作台的V形圆导轨面如图17所示,测量时在工作台中央孔中紧密地配入一根心轴,心轴的上半段套入一个与心轴外圆保留微小间隙(一般不大于0.02mm),且能在心轴上转动的转套,从转套侧面延伸出表杆,测量用的百分表就固定在表杆的悬臂上,并随转套旋转一周进行测量读数。 First, the dial indicator measurement with a dial indicator V-shaped vertical lathe table rail surface as shown in Figure 17, measured in the table center hole tightly with a mandrel, mandrel The upper half of the set into a small gap with the mandrel to keep a small gap (usually not more than 0.02mm), and can rotate on the mandrel rotating sleeve, extending from the side surface of the table rod, measuring dial indicator on the fixed Table cantilever arm, and rotate with the rotation of a week to take measurements readings.
