一些机械零件的长轴因拆装时不注意,使顶针孔偏位,这样就需要重新加工顶针孔,才能进行修理。针对这种情况,采用了一种简单工具(如图示),使许多顶针孔偏位及无顶针孔的长轴都得到修理。这一工具结构简单,校正方便,能达到修理精度要求。使用时,将套筒2上的顶针孔1顶住车床顶针上,工件放在套筒2内,用调节螺钉4 Some mechanical parts of the long axis due to disassembly do not pay attention to the thimble hole offset, so you need to re-processing thimble hole to be repaired. In response to this situation, a simple tool (pictured) was used to correct the misalignment of many thimble holes and the long axis of the thimble-free holes. This tool has the advantages of simple structure, convenient calibration and can meet the requirements of the precision of repair. When used, the thimble hole on the sleeve 2 to withstand the thimble on the lathe, the workpiece placed in the sleeve 2, with the adjustment screw 4
