在成批生产中,测量锥孔一般都用专用验规,但在锥孔直径较大或工件数目不多时,专门做一个验规就不合算了。这时可以用如附图的锥孔测量卡尺,来测量锥度、锥角和直径。附图中,1是外壳,上面有固定不动的定位量瓜 a。2是直径量尺,上面有直径量爪 b。3是锥度量尺,上面有锥度量爪 c。a 和 b 的爪端离外壳下平面为5公厘,c 的爪端离 a 的爪端的垂直距离为10公厘。4和5是游标。6是盖板,7是滑架,8是微动螺丝,9是固定螺丝。
In mass production, measuring conical holes are generally used for special inspection, but in the larger cone diameter or a small number of workpieces, it is uneconomical to do a special inspection. In this case, you can measure the taper, taper angle, and diameter by measuring the caliper with a taper hole as shown in the attached drawings. In the drawings, 1 is the housing, above a fixed amount of positioning melon a. 2 is a diameter gauge, above the diameter of the amount of claws b. 3 is a taper gauge, above the taper claw c. The claw ends of a and b are 5 mm from the lower plane of the housing, and the vertical distance between the claw end of c and the claw end of a is 10 mm. 4 and 5 are cursors. 6 is a cover, 7 is a carriage, 8 is a fretting screw, 9 is a fixing screw.
