Bolt fastening method based on electromagnetic clutch self-adaptive bolt tightening device

The invention belongs to the technical field of power angle steel tower bolt fastening operation, and particularly relates to a bolt fastening method based on an electromagnetic clutch self-adaptive bolt tightening device. The electromagnetic clutch self-adaptive bolt tightening device comprises a self-centering chuck installed on a rack and a striking power source used for driving the self-centering chuck to generate self-rotation action. When the bolt is fastened, the nut end of the bolt to be tightened is sleeved with the self-centering chuck in an opening mode, and meanwhile the electromagnetic clutch is matched with the clamping power source and the striking power source, so that it is guaranteed that tightening operation is completed. The multi-purpose bolt mounting machine can adapt to mounting operation of bolts of different specifications, on-line sleeve replacement is not needed, and meanwhile the multi-purpose bolt mounting machine has the advantage of being stable and flexible in work. 本发明属于电力角钢塔螺
