某水电站施工工地上的维修人员充分利用磁座电钻能方便可靠地吸附在钢铁等磁性材料上实现多向钻孔,该方法具有转速低、输出转矩和轴向力较大、钻孔速度快等特点,通过加钻套还可以提高钻孔精度。在磁座电钻的电磁吸盘底部加装1个抱箍并点焊,用以防止侧吸在左右侧板上的磁座电钻在钻削过程中因机械振动可能产生的移位,解决了使用普通手电钻高速旋转切削产生高温及冷却液被大量抛出、导致钻头易过热退火等难题,成功地取出在自行式振动压路机上的高强度断螺栓。
A hydropower station construction site maintenance staff make full use of magnetic seat drill can be easily and reliably adsorbed on magnetic materials such as steel to achieve multi-directional drilling, the method has low speed, output torque and axial force, drilling speed And so on, by adding drilling sets can also improve drilling accuracy. Magnetic chuck in the magnetic chuck to install a bottom of the hoop and spot welding to prevent side suction in the left and right side of the magnetic drill plate in the drilling process due to mechanical vibration may have shifted to solve the use of ordinary Hand drill high-speed rotary cutting high temperature and coolant is thrown a lot, leading to bit easily overheating annealing and other challenges, successfully remove the self-propelled vibratory roller broken high-strength bolts.
