摇臂钻床,经多年使用后,出现立柱与摇臂内孔的不均匀磨损或严重擦伤,影响了机床精度和使用。为此,我厂进行了镶套修理,效果良好。具体结构如图,立柱在原直径尺寸上车削减小,精车后,用电接触表面淬火淬硬表面,打光。摇臂内孔镶套,并在套的两端加装防尘圈。套用树脂粘接于臂的内孔并用螺钉加固,套的材料用 Radial drilling machine, after years of use, the column and the rocker arm bore uneven wear or serious abrasion, affecting the accuracy and use of the machine. To this end, I set the factory set of repair, the effect is good. The specific structure shown in Figure, the column diameter reduction in the original turning to reduce the fine car, the surface hardened electrical contact with hardened surface, light. Swing arm hole set, and at both ends of the sleeve installation of dust ring. Apply resin to the inner hole of the arm and use screws to reinforce the sleeve
