在当前机修行业的测绘和制造过程中,测量非图1　非整圆零件半径测量专用量具结构示意图整圆零件的半径可以采用图1所示量具。首先把被测零件装入量具的主、副尺之间,使零件有2点与主、副尺相切,并用螺母锁紧,然后利用百分表找准切点位置,读出卡尺上的读数L,测出主、副尺间夹角 In the current machinery industry mapping and manufacturing process, measurement of non-round parts of non-circular measuring device for measuring the radius of the structure diagram of the radius of the round parts can be used as shown in Figure 1 measuring tools. First of all the measured parts into the measuring device between the main, deputy ruler, the parts have 2 points, the main and auxiliary feet tangential, and with the nut lock, and then use the dial indicator to find out the location of the cut point, read the caliper Reading L, measured between the main, deputy ruler angle
