在量具修理工作中,我们经常碰到车间生产工人在使用百分表时,由于不慎将表蒙撞坏、摔裂的情况,这不仅影响表的外观质量,而且极易损伤表的其它部分和精度。为此必须及时更换已损坏的表蒙。对于那种平面表蒙较易更换,但我们所遇到的大多为鼓形(圆弧)表蒙。要把买来的平面表蒙装到表圈的止口上,并使其成凸弧状就比较困难。过去曾采用加热或手压法操作比较麻烦费时。后来修理人员自己动手制作了一个压表蒙工具,经使用较为理想,该工具构造简单,操作方便。
In the gage repair work, we often encounter the workshop production workers in the use of the dial indicator, due to inadvertent watch Meng Meng crashed, the case of splitting, which not only affects the appearance of the appearance of the table, and can easily damage the rest of the table And precision. To this end must be promptly replaced damaged table Meng. For the kind of plane table easier to change, but we have encountered mostly drum (arc) table Mongolia. It is more difficult to mask the purchased flat surface to the bezel of the bezel and make it convex. In the past, it was troublesome and time-consuming to use heating or hand-pressing method. Later, the repairer made a self-made pressure gauge and a tool that was ideal for use. The utility model has the advantages of simple structure and convenient operation.
