我厂使用的千分尺,由于有的用于单一产品生产,只经常使用某段部位,有的长时间缺乏检修,丝杆磨损十分严重,造成千分尺示值误差较大,给修理时带来很大的工作量,以前用手工修理,劳动强度大,而且不易掌握。针对这种情况,我们用一台手摇绕线机改成手摇丝杆研磨机,通过近两年来的实际使用,效果很好,操作简便,易于掌握,缩短了修理时间和减轻了劳动强度,以前一根丝杆修复需3至5小时,而现在一小时左右就可以了,并且它适用范围广,只要采用不同的夹具就能研磨各种千分尺的丝杆。手摇丝杆研磨机如图1所示。
I use the micrometer plant, because some for a single product, only often use a site, and some lack of maintenance for a long time, screw wear is very serious, resulting in a larger error indication micrometer, to bring great repair The workload, previously used manual repair, labor-intensive, but not easy to grasp. In view of this situation, we use a hand winding machine into a hand crank grinder, through the actual use of the past two years, the effect is very good, easy to operate, easy to grasp, shorten the repair time and reduce labor intensity , Before a screw repair takes 3 to 5 hours, and now an hour or so on it, and its wide range of applications, as long as the use of different fixtures will be able to grind a variety of micrometer screw. Manual screw grinder shown in Figure 1.
