为了测量某产品在工作时的瞬时弹性变形量,起初采用普通百分表测量,由于变形是瞬时的,百分表在显值后又迅速返回零位,示值无法看清,若采用照相示值,势必增加测试成本。在机修组同志的配合下,我们利用了一只废百分表改制了一只“定值百分表”,结构如图。只是在百分表的外壳上加两只弹簧支撑,其压力和约为200克,(比百分表复位弹簧压力150克大即可),另在表头轴上端加一只铜套,
In order to measure the instantaneous elastic deformation of a product at work, initially using an ordinary dial indicator measurement, the deformation is instantaneous, the dial indicator returns to zero immediately after the display value, indicating the value can not be seen, if the use of photographic Value, bound to increase the cost of testing. In cooperation with the mechanics group comrades, we used a waste dial to modify a “dial indicator”, the structure shown in Figure. Only in the case of the dial indicator plus two spring support, the pressure and about 200 grams, (than the dial indicator spring pressure of 150 grams can be large), the other in the table head shaft plus a copper sleeve,
