这里介绍的研磨工具可用于修理各种端面与其轴心线垂直的工件,如测量杆、调整量具、测头、大型千分尺的活动测杆及可换测杆、内径表顶杆、螺纹千分尺测头等。此种研磨工具的结构,由螺钉M8×45以及附表所列四种零件组成(参看附图),V形块3的 V 面与底面不垂直度不大于0.002。底座4的工作面和 V 形块3的底面的光洁度都应达到10级。V 面与底面的垂直度的检查,可按下述方法进行。将外圆几何形状误差很小的标准圆柱装在 V 形槽中进行试研,使圆杆位置转动90°,再研一研,然后检查研磨纹路是否交叉来判断,也可将校准量杆(端面与其轴心线垂直)装在 V 形槽中,在
The grinding tools described here can be used to repair a wide range of workpieces that have their end faces perpendicular to their axis, such as measuring rods, adjusting gauges, probes, large and active micrometers moving and measuring rods, ID tables, threaded micrometer probes, etc. . The structure of this grinding tool, screw M8 × 45 and the table listed in the four components (see the figure), V-shaped block 3 V-plane and the bottom surface of not more than 0.002. The finish of the base 4 and the bottom surface of the V-block 3 should all reach 10 levels. The verticality of the V surface and the bottom of the inspection, can be carried out as follows. The outer cylindrical geometry error is small standard cylinder installed in the V-groove trial, so that the rod position rotated 90 °, and then a research, and then check whether the intersection of grinding lines to judge, but also the calibration rod (end Perpendicular to its axis) mounted in the V-groove, at
