外径千分尺经过较长的时间使用以后,尺架孔被磨损大了,我厂采用万能胶胶合铜套的方法来修理,经过较长时间的考验,证明效果尚好。修理工作可分为修理测杆、配制铜套、扩尺架孔和胶合铜套等四步进行。1.测杆的修理首先检查测杆与尺架孔的配合情况,若确需修理时,先将测杆用图1所示的测杆研磨工具在车床上进行研磨。研磨时,将微分筒、棘轮和测杆的组合体从固定套管中回转出来,微 Outer diameter micrometer after a long period of use, the square frame hole is worn big, I plant using universal glue glued copper sleeve to repair, after a long period of test, the proof is still good. Repair work can be divided into repair test rod, the preparation of copper sets, expansion frame hole and glued copper sleeve and other four-step process. 1. Rod repair First check the rod and the frame hole with the situation, if indeed need to be repaired, the first rod with the rod shown in Figure 1 grinding tools on the lathe grinding. Grinding, the differential cylinder, ratchet and rod combination of rotating out of the fixed casing, micro
