一、百分表测杆径向摆动的消除以前我们也是采用钢球冲击铜套口来缩小孔径,但效果不大满意。碰到铜套与套筒配合不很紧的,一冲就向内滑,较难冲。后来我们制作了如图1所示的工具,在铜套内挤出一条螺旋线,来消除测杆的径向摆动,效果较好。使用时先拿去扳手1,把螺母套3旋出, First, the dial indicator to eliminate the radial swing We used the ball before the impact of copper sleeve to narrow the aperture, but the effect is not satisfactory. Encounter with the copper sleeve and the sleeve is not tight, a red slip inward, more difficult to punch. Later, we made a tool shown in Figure 1, the extrusion of a spiral within the copper sleeve to eliminate the radial test rod swing, the better. First take the wrench when used 1, the nut 3 sets out,
