一台自行式振动压路机断裂了8只高强度螺栓,使用磁座电钻(见图1)可将其轻易取出。操作时,为确保钻孔中心定位准确及钻进过程中不偏心,在沉孔处加装1个钻套(见图2),钻套与侧板沉孔之间的配合间隙为0～0.03mm,钻套孔与麻花钻头的配合间隙为0.03～0.05mm。由于侧板上有油漆等污物,电磁吸盘的吸附力会有所减弱,侧吸在左右侧板上的磁座电钻在钻削过程中也因机器振动会产生位移。可在磁座电钻的电磁吸盘底
A self-driven vibratory roller breaks eight high strength bolts that can be easily removed using a magnetic drill (see Figure 1). Operation, in order to ensure accurate drilling center positioning and drilling process is not eccentric, install a drill in the sink hole (see Figure 2), drill sleeve and the side of the counterbore with the gap between 0 ~ 0.03 mm, drill hole and twist drill with the gap of 0.03 ~ 0.05mm. Due to paint on the side panels and other dirt, the suction force of the electromagnetic chuck will be weakened, side suction on the left and right side of the plate on the magnetic drill in the drilling process due to machine vibration will produce displacement. Electromagnetic chuck can be used in magnetic drill base
