为了解决端面齿高和尖底沟槽的检测问题,可将卡尺的外量爪进行改制,如图1所示,用线切割机割去外量爪端部,再将主尺外量爪端加工成20°角。改制后的卡尺功能基本不受影响,减少了阿贝误差,并能测最角度大于40°的齿高和沟槽深等。如汽轮机调速器零件错油门滑阀端面齿高的测量(图2)。先用卡 In order to solve the face tooth height and the bottom of the groove detection problems, calipers can be modified outside the claw, as shown in Figure 1, cut with a wire cutting machine end of the outer claw, Processing into a 20 ° angle. After the restructuring of the basic function of the caliper is not affected, reducing the Abbe error, and can measure the most angle greater than 40 ° tooth height and groove depth and so on. Turbine governor parts such as valve sliding valve tooth height measurement (Figure 2). First card
