如图所示,我们通过实测的样块宽、支架中心高和侧面高度,而不需转动工件180°测量,就能得到轴截面对称度误差值,测量面的调平只需一次, 既能提高工件检测效率,又能提高检测精度。实测样块或花键键宽为 b,支架中心距底面高度为 L,测量面调整到与底面平行后的高度为 M,轴径(花键为大径)为d,槽深(花键键高)为 h,e 为被测键槽或花键中心平面到轴中心平面的距离,
As shown in the figure, we can get the symmetry error of shaft cross-section by measuring the width of the sample, the height of the center of the bracket and the height of the side, without measuring the 180 ° rotation of the workpiece. The leveling of the measuring surface is only needed once, Improve the efficiency of workpiece inspection, but also improve the detection accuracy. The measured sample or spline key is b, the height of the center of the bracket from the bottom is L, the height of the measurement surface is adjusted to be parallel to the bottom surface after M, the shaft diameter (spline is large diameter) is d, the depth of the spline High) is h, e is the distance from the center of the spline or spline center plane to the center plane of the shaft,
