我厂生产的机床上的丝杆,都是担任精密位移工作的。它同螺母配合的间隙要求很高,用一般的检验方法很难得出准确的结果。在生产大跃进中,经过同志们的苦干、实干,设计成功一套检验工具,用它来检验机床传动丝杆和螺帽的配合间隙非常方便。这个检验工具的原理是根据扳手受力后所产生弹性变形的大小,来测定丝杆和 I plant the screw on the machine, are working as a precision displacement. It is with the nut with the gap demanding, with the general test method is difficult to draw accurate results. In the Great Leap Forward, after comrades work hard, hard work, the design of a successful test tool, use it to test machine drive screw and nut with the gap is very convenient. The principle of this test tool is based on the size of the elastic deformation generated by the wrench, to determine the screw and
