使用中和修理后的千分尺,由于微分筒与丝杆轴向相对位置变动、测量面的磨损以及螺旋付的单向磨损等原因,常常造成压线或离线现象。过去我们修理上量、北量等厂生产的千分尺的压离线是用冲子敲击,以改变弹簧锥套与微分筒的相对位置。这种方法往往要反复多次才能调准,既费时间又易损坏微分筒。经过实践,我们自制了一个“千分尺微分筒压离线调整工具”,使用效果较好,只要预先测算好压离线的数值就能一次成功。现将工具及使用方法简介如下。如千分尺微分筒离线,先测算出离线的距离, Use and repair of the micrometer, due to the axial movement of the differential cylinder and screw shaft relative position, the wear of the measuring surface and the spiral pay unidirectional wear and other reasons, often resulting in pressure line or offline. In the past we repaired the volume, the North mill and other factory production micrometer pressure line is knocked with a punch to change the relative position of the spring cone and the differential cylinder. This method is often repeated several times to adjust, it is time-consuming and easy to damage the differential cylinder. After practice, we made a “micrometer differential cylinder pressure off-line adjustment tool,” the use of better, as long as the pre-measured value of pressure off the line can be a success. Now the tools and methods of use are as follows. Such as micrometer tube off-line differential, first measured off-line distance,
