牵引车、推土机、汽车起重机等工程机械在使用一段时间后,其后桥各定位孔、定位端面等磨损了,车体或支架会有不同程度的变形,需要修理,而首先要解决的问题是要有能够检测的工具。为此,我们从76年开始进行了光检后桥的研究;78年试制出坦克底盘牵引车后桥光学检查仪;该仪器体积小、重量轻、操作方便,曾在全国科学大会上展出,被评为先 Tractors, bulldozers, truck cranes and other construction machinery in use for some time, the rear axle positioning holes, positioning end face and so on, the body or stent will have varying degrees of deformation, the need to repair, and the first problem to be solved There is a tool that can be tested. To this end, we started from 76 after the optical inspection of the bridge after the study; 78 years to produce a tank chassis tractor rear axle optical inspection instrument; the instrument small size, light weight, easy to operate, once exhibited at the National Science Conference , Was rated first
