我厂购置的一台(天津市机床光学仪器厂生产的) TC,凸轮测量头,因分划板不能移动,而无法象其他测量头一样通过移动分划板进行调“零”,以取得以毫米为整数的凸轮升程起始值,给我厂的凸轮测量工作带来了困难。我们通过摸索,在不更换原设计构件的前题下,对TC_1凸轮测量头的调“高”机构作了一些改进,既保持了测量头的调“高”,又实现了测量头的调“零”。现将改进方法介绍如下,供参考。当我们在测量头下斜板的两端和上斜板的中间各固定两个挡条,并在下斜板的挡条上装上三个螺钉(一端一个,另一端两个,三个螺钉的位置由上向下看时呈等腰三角形) 后,当
I purchased a plant (Tianjin Machine Tool Optical Instrument Factory production) TC, cam measuring head, because the reticle can not move, but not like other measuring heads through the same move the reticle to adjust “zero” to obtain The starting value of cam lift for millimeters is an issue that has caused difficulties for our cam measurement. We have made some improvements to the “high” mechanism of the TC_1 cam probe without changing the original design components, and not only maintained the “high” of the probe but also realized the adjustment of the probe “ zero”. The improved method is introduced below, for reference. When we are in the measuring head under the ramp at both ends of the ramp and the middle of each fixed two block, and in the lower ramp plate mounted three screws (one at each end, two at the other end, the location of the three screws When viewed from the top was an isosceles triangle) when
