我们在日常量具修理中,经常修理0—125毫米的游标卡尺。过去修理此尺的测深尺时,是采用靠铁研磨顶面,有一段时间则用油石打磨,用上述方法都很费力,既不易掌握,工作效率不高,精度也达不到要求。后来我们用一铸铁件车制成如图所示的研磨胎具,使用时将胎具放在平板上,再将需要研磨的卡尺尾端插进胎具,(?)16.5的孔内,垫上铜板,用固紧螺钉夹紧,就可进行研磨。 We routinely repair 0-125 mm vernier caliper. In the past to repair the ruler of this ruler, it is to rely on iron grinding the top, there is a period of time with oilstone grinding, the above methods are very laborious, not easy to grasp, the work efficiency is not high, the accuracy does not meet the requirements. Later, we use a cast iron car made as shown grinding abrasive, the use of the tire on the flat, then the need to grind the end of the caliper into the tire, (?) 16.5 hole, pad Copper plate, tighten with a fastening screw, you can grind.
