在加工弹性夹簧之类的零件时,因内腔直径大,两端直径小,无法用通用量具来测量,一般只能靠看刀架上的刻度进刀来保证。我们制成一种内孔测量器,测量范围为φ8～φ110,使用方便,精度也较高。活动卡脚2的活动范围为20mm,使用前先按被测零件孔径的大小,松开螺母14,将固定卡脚1调整在大致范围内,并使活动卡脚有一定的压缩量,然后拧紧
In the processing of flexible parts such as spring clip, due to the lumen diameter, both ends of the small diameter, can not be measured with the universal measuring tools, generally can only rely on the knife to see the knife on the scale to feed. We made a bore measuring instrument, measuring range φ8 ~ φ110, easy to use, high precision. Activity card feet 2 activity range of 20mm, before use according to the size of the measured part of the aperture, loosen the nut 14, the fixed pin 1 adjust the approximate range, and the activity has a certain amount of compression feet, and then tighten
