在轮对检修流水线或自动机床上,常常需要把上工序流入下工序的轮对在某处定位,以便进行加工。如图1所示,轮对O以速度V运动到机床的主轴中心G处自动地停下来。为此,我们很容易想到在中心A处作一凹坑mAn,但这将造成很大的冲击,对装有电子设备的现代化机器,如装有光栅计 In the wheel alignment or automatic machine tools, often need to flow into the next process on the process of positioning the wheel somewhere in order to carry out processing. As shown in Figure 1, the wheelset O is automatically stopped at the speed V at the spindle center G of the machine. For this reason, it is easy to think of making a dimpled mAn at the center A, but this will have a great impact. For modern machines equipped with electronic equipment, such as a grating meter
