这里介绍一种测量花键塞规的齿距相邻误差和累积误差的方法。对于外圆小于100mm的矩形花键塞规,我厂用光学分度头与小型电感比较仪支架加扭簧表测量。用分度头测得理论角度做定位基准,用扭簧表直接测出线性误差值。方法简便,精度基本可靠。测量方法如下: 1.将花键塞规装在光学分度头的顶尖上,如图示。将装有扭簧表的小型电感比较仪支架放在光学分度头的台面上,自制的杠杆测头3装在扭簧表上,然后调整位置使杠杆测头一端与被测花键的某一齿侧面接触(尽量靠近
Here is a method to measure the pitch error of the spline plug gauge and the cumulative error. For the external circle less than 100mm rectangular spline plug gauge, I plant with an optical indexing head and small inductance comparator bracket plus torsion spring table measurement. Using the theoretical angle of the dividing head to measure the positioning datum, the torsion spring gauge is used to directly measure the linear error value. The method is simple and the accuracy is basically reliable. The measurement method is as follows: 1. The spline plug is mounted on the top of the optical indexing head, as shown. Will be equipped with a torsion spring table compact inductor comparator stand on the table optical indexing head, self-made lever probe 3 mounted on the torsion spring table, and then adjust the position so that one end of the lever probe and the measured spline One tooth flank contact (as close as possible
