[0035] Working principle: When in use, when synchronously adjusting the heights of the first base 1 and the second base 2 in the rudder blade taper hole boring and processing device, the output end of the servo motor 9 drives the spline sleeve 91 and the spline shaft 8 to rotate synchronously, so that the fourth bevel gear 81 at the end drives the third bevel gear 74 on the same side, so that the transmission gear 73 drives the rotating gear 71, so that the lifting screw column 72 can lift along the internal thread of the rotating gear 71, so that the machine head 6 and the frame 3 on the tops of the first base 1 and the second base 2 can be lifted synchronously, making it fast and convenient to adjust and adapt the height of the taper hole boring and processing device to the rudder blade;
