控制千分尺测量精度的主要零件是测微丝杆。这种丝杆往往由于磨损不均匀等原因而使精确度降低。为了恢复其精确度,所以在使用一定时间以后就得进行研磨。如果采用手工研磨,不仅工时消耗量很大,且质量也难保证。针对这个问题,我们制成了一台研磨机,从而解决了修理工作中质量和效率问题。这种研磨机结构简单(如图示),操作容易,整个机构由电动机18,通过皮带轮17、16.带动摩擦轮12旋转。此时若操纵手柄8,使齿轮4带动齿条滑筒3沿轴向移动,并使研磨机主轴2尾端的夹布胶木摩擦轮11与旋转中
The main part that controls micrometer accuracy is the micrometer screw. This screw is often due to uneven wear and other reasons to reduce the accuracy. In order to restore its accuracy, so after a certain period of time have to be ground. If you use manual grinding, not only the consumption of man-hours, and the quality is difficult to guarantee. In response to this problem, we made a grinder, which solved the quality and efficiency of the repair work. The grinder has a simple structure (as shown) and is easy to handle. The entire mechanism is driven by the motor 18 through the pulleys 17 and 16. The friction wheel 12 is driven to rotate. At this time, if the handle 8 is manipulated, the gear 4 drives the rack cylinder 3 to move in the axial direction, and the clamping rubber bush 11 at the rear end of the grinding spindle 2 rotates
