千分尺测杆与尺架导孔之间间隙过大所产生的径向摆动,不但影响两测量面的平行性变化,也会给平面平行性的修复造成困难。百分表测杆的径向摆动将影响示值稳定性。消除径向摆动的方法虽然很多,但根据我们的实践,认为加焊薄铜套圈的方法较为优越。此法操作简便、工效高、便于多次修理、修理质量好、修后使用寿命长。图1是在千分尺尺架和冒分表下套筒上加焊套圈的情况。通常套圈尺寸可按下表所列的几种规格 The radial swing caused by the gap between the micrometer rod and the guide hole of the scale frame is not only affected by the change of parallelism of the two measurement surfaces, but also causes difficulty in repairing the plane parallelism. The radial oscillation of the dial indicator will affect the indication stability. Although many ways to eliminate radial swing, but according to our practice, that the method of welding thin copper ferrule is superior. This method is easy to operate, high work efficiency, easy to repair many times, good repair quality, long service life after repair. Figure 1 is in the micrometer scale frame and spike under the sleeve on the weld ring. The size of the ferrule is usually as specified in the following table
