矩形花键塞规的横截面对称度一般都在光学分度头上测量,比较麻烦。我们在万能工具显微镜上用影像法测量简单易行,单个及多个键都能测量,精度可靠。方法如下:首先加工一个外圆大于150mm的圆形托盘。然后把被测塞规上端面用磨床磨一下,以保证塞规键梗与端面垂直。然后把塞规的手柄穿入托盘孔中,一同放在万能工具显微镜上,如图所示。调整焦距和工件,使 Rectangular spline plug gauge cross-sectional symmetry are generally measured in the optical sub-head, more trouble. We use the omnipotent tool microscope imaging method is simple, single and multiple keys can be measured, the accuracy and reliability. The method is as follows: First, process a circular tray with an outer circle larger than 150mm. Then the measured Cypriot end face grinding with a grinder to ensure that plug the key stem and end face vertical. Then plug the gauge handle into the tray hole and place it on a universal tool microscope as shown. Adjust the focal length and the workpiece so that
