我厂加工的球笼成形模（如图1所示）·，以前测量内球面中心分合面，是采用与孔山配合的销轴及两只普通钢球来测量成形模右端面至钢球的实际尺寸H（如图2所示），然后减去标准尺寸h，唐去所得尺寸（H－h），以保证内球面中心分合面尺寸。由于测量尺寸H所使用的量具为深度尺，使 I plant processed ball cage forming mold (shown in Figure 1) ·, before measuring the inner spherical center divisions, the hole is used with the pin and two ordinary steel ball to measure the right side of the mold to the ball Of the actual size H (shown in Figure 2), and then subtract the standard size h, Tang to get the size (H-h), in order to ensure that the spherical center sub-surface size. As the measuring size H used by the gauge for the depth scale, so
