在修理齿輪卡尺时,测量爪和高度尺端面的研磨是比較困难的。为减輕这道工序的困难合理地采用了专門的研磨棱鉄(图1)。研磨棱铁平面a和S要具有0.002毫米精度的平行性。尺寸h和L做成与齿輪卡尺的尺寸相适应。尺寸L为40～50毫米;为了能够用量块調整高度,尺寸h适当地做得此齿輪卡尺的卡爪长度小1.5毫米。根据样板尺把高度尺(图 2) 調整得与卡爪一样高并固定下来。移开活动卡爪,把齿輪卡尺放到棱鉄上。把高度尺置入棱鈇的槽中。然后把活动卡爪引向棱铁并于固定。并把棱鉄与齿輪卡尺置于平板上,同时在刻度尺与棱鉄之間形成的間隙放置量块1,
When repairing the gear caliper, it is more difficult to grind the measuring jaw and the height scale end face. To alleviate the difficulties of this process reasonable use of a special grinding ridge 鉄 (Figure 1). Grind the prismatic planes a and S with a parallelism of 0.002 mm accuracy. The dimensions h and L are made to fit the size of the gear caliper. The dimension L is 40 to 50 mm; in order to be able to adjust the height with a measuring block, the dimension h is suitably made such that the length of the jaw of this gear caliper is less than 1.5 mm. Adjust the height gauge (Figure 2) to the same height as the jaws and secure them according to the model ruler. Remove the movable jaw and place the gear caliper on the ridge. Place the height ruler into the ridge ridges. Then move the activities of the claw lead to the edge of the iron and fixed. And the ridge ridges and gear caliper placed on the flat, while the gap between the scale and ridge 放 placed the amount of block 1,
