内径千分尺是用来测量内孔的一种精密量具,在机械行业中使用极普遍,由于用得多,接杆容易磨损,我厂计量室在实践工作中摸索出敲打挤长的办法来进行修理,具有简易和快速的特点,方法如下,供同志们参考. 一、将磨损了的接杆心子拆卸,并用零级外径千分尺测量心子的长短,确定磨损量. Micrometer inside diameter is used to measure a precision measuring hole in the hole, the use of machinery in the industry is extremely common, due to much more, the post is easy to wear, I plant measurement room in the practice of work to find out a long way to beat knocking to repair , With a simple and fast features, the method is as follows, for the comrades reference.First, the worn rod heart disassembly, and with zero-level diameter micrometer to measure the length of the heart, to determine the amount of wear.
