我们把报废的千分尺,卸下锁紧装置和微分筒及测力装置,锯掉尺架,根据相配内径量表表杆的直径,在原锁紧装置处钻通孔,测微杆孔攻丝,配M8项丝。用火加热A点弯至与丝杆成90°角,在B处钻φ2.5小孔,把百分表测头的小钢珠镶入焊牢。将丝杆从固定套筒的后部旋入,用废千分尺的调解螺母紧固。如图1所示。把改造后的千分尺装入内径量表。先计算出孔距的理论尺寸数值,如图
We scrap the micrometer, remove the locking device and the differential cylinder and the force measuring device, saw off the square frame, according to the diameter of the gauge table to match the diameter of the hole in the original locking device drilled through the micro-rod tapping, With M8 items silk. A point with the fire heated to a 90 ° angle with the screw, drill φ2.5 holes in the B, the small ball of the dial indicator probe set in the prison. Screw the screw from the rear of the fixing sleeve and fasten it with the adjusting screw of the spent micrometer. As shown in Figure 1. The modified micrometer into the internal diameter scale. Calculate the theoretical size of the hole pitch values, as shown
