在精密加工和精密测量中,都需要有高精度的分度盘,作为回转运动的分度元件,这类元件在相邻齿(槽)距和累积齿(槽)距方面均具有较高的精度要求。在制造这类高精度的分度元件时,大多是运用圆周分度误差具有封闭性的原理,设计制造出相应的装置,通过多次测量相邻齿(槽)距的相对误差,计算出齿(槽)距的误差真值和最大累积误差,找出合理的加工位置,从而保证分度盘的加工精度。这种方法虽然解决了精密分度盘的加工问题,但加工操作起来很不方便。下面介绍一种简便
In precision machining and precision measurement, a high-precision indexing plate is required as an indexing element for rotary motion. Such elements have a high ratio of adjacent tooth (groove) pitch and cumulative tooth (groove) pitch Accuracy requirements. In the manufacture of such high-precision indexing components, mostly the use of the principle of circular indexing error is closed, the design and manufacture of the corresponding device, by measuring the relative distance between adjacent teeth (groove) the relative error to calculate the teeth (Slot) the true value of the error and the maximum cumulative error to find a reasonable processing position, thus ensuring the accuracy of the sub-plate. Although this method to solve the problem of precision indexing plate processing, but the operation is very inconvenient. The following describes a simple
