At this time, the third pawl 518-1 and the fourth pawl 518-2 on the third rotating shaft drive the second gear 517 to rotate, which is specifically the following: if the third slider 524 moves upward to drive the rocker 518 to rotate counterclockwise, the third pawl 518-1 will drive the second gear 517 to rotate counterclockwise, so as to drive the first incomplete gear 516 to rotate counterclockwise by an angle; if the third slider 524 moves down to drive the rocker 518 to rotate clockwise, the fourth pawl 518-2 drives the second gear 517 to rotate clockwise, so as to drive the first incomplete gear 516 to rotate clockwise by an angle. When the number of times of repairing the second tool 42 is too many and a plurality of continuous errors are positive values or negative values, it indicates that the error caused by processing the first tool 41 is not an accidental situation, and even if adjustment is needed, the error is prevented from increasing, so that the rocker 518 rotating for many times drives the first incomplete gear 516 to rotate for a full circle, so that the first complete gear 513 rotates, the first complete gear 513 rotates to drive the second screw 512 to rotate to adjust the feeding amount of the first tool 41, the processing error of the first tool 41 is reduced, the product yield is improved, the cost is saved, and the efficiency is improved. In addition, when the single repair feeding distance of the second tool 42 is too large, it is indicated that the error deviation of the first tool 41 is large, and the adjustment is required in time to avoid the scrapping situation, so that the single repair feeding distance of the second tool 42 is too large, which causes the moving distance of the third slider 524 to be also large, the rotation angle of the rocker 518 to be large, and the rotation angle of the first incomplete gear 516 to be also large, so that the first complete gear 513 may directly adjust the feeding distance of the first tool 41 under the condition that the second tool 42 is repaired once or a few times. The motor shaft repairing and polishing device can drive the second cutter 42 to repair and polish according to the detection result of the detection mechanism 6, so that the qualification rate of the motor shaft is improved, mass reworking and scrapping are avoided, and the production cost is reduced; and when the detection mechanism 6 detects that a plurality of continuous errors of the machining errors of the first cutter 41 are positive or negative values, the feeding parameters of the first cutter 41 are adjusted through the second adjusting unit, so that the machining errors of the first cutter 41 are reduced, the product yield is improved, the cost is saved, and the efficiency is improved.
