将游标卡尺刀口形内量爪改成活动量爪,可避免采用挤压、敲击法使刀口内量爪复零时损坏量爪。具体做法:先把尺框内量爪刀口部分去掉,再制作一个活动刀口形内量爪1(图1);两条固定靠板2固定在尺框背面,靠板端面平行于尺框平面。为复零准确,还可附加微调装置(图2),微调座板固定在原微动装置上。 The vernier caliper knife into the amount of activity within the amount of claws, to avoid the use of squeezing, tapping method so that the knife within the amount of claw zero zero complex damage claws. The specific approach: the first volume within the scope of the claw knife part removed, and then make an active knife-shaped inner claw 1 (Figure 1); two fixed by 2 fixed to the back of the frame, the plate end parallel to the plane plane. For complex zero accurate, but also additional fine-tuning device (Figure 2), fine-tuning the base plate fixed to the original micro-device.
