在车床卡盘上校准外形不规则工件的中心,往往是比较麻烦的事情。然而,应用本文所介绍的辅具,找正中心就方便多了。如图所示,取一光轴,它一端车削成60°锥尖,另一端用铜焊与U型弹簧钢板相焊,并在U型弹簧钢板的外侧钻一个小孔,将轴放置在尾座顶针与工件中心记号之间,然后用手旋转卡盘,同时用千分表测头靠在工件一端的光轴上,即可迅速显示出工件的偏心度。圆光轴不转动。60°锥尖与弹簧板侧孔的同心度
Calibrating the center of irregularly shaped workpieces on a lathe chuck is often a troublesome task. However, using the aids described in this article, it is much more convenient to find the center. As shown in the figure, taking an optical axis, one end turned into a 60 ° cone tip, the other end is brazed with U-shaped spring steel plate and a small hole outside the U-shaped spring steel plate, the shaft placed at the tail Between the thimble and the center of the workpiece mark, and then rotate the chuck, while using a dial gauge probe on the optical axis of the workpiece at one end, you can quickly show the eccentricity of the workpiece. Circular optical axis does not rotate. Concentricity of 60 ° cone tip and spring plate side hole
