矩形花键拉刀是高效精密成形刀具,因此,花键不等分累积误差和键侧对轴心线的不平行度,这两个精度项目被列为主要精度项目。测量这两个精度项目需要专门的测量仪器。为了保证花键拉刀的质量,我们在原有的两台1.5m长的偏摆检查仪上进行整修和改装。经过使用,效果较好、量值准确、读数稳定、使用简便、操作省力。其结构示意如图1。首先,把原偏摆检查仪的导轨表面作了整修,提高了几何精度,使导轨面的不直度在全长范围内用平行光管检查不超出0.015mm;两顶针座不等高误差不
Rectangular spline broach is a highly efficient precision forming tool, therefore, the spline does not divide the cumulative error and key side of the axis of the non-parallelism, these two precision projects are listed as the main precision project. Measuring these two precision items requires specialized measuring instruments. In order to ensure the quality of the spline broach, we renovate and modify the original two 1.5m long deflection tester. After use, the effect is better, the amount of accurate, stable readings, easy to use, easy operation. The structure shown in Figure 1. First of all, the original deflection tester surface of the rail made a renovation to improve the geometric accuracy of the rail surface is not straight in the scope of the entire length of the collimator check does not exceed 0.015mm; two thimble unequal height error is not
