[0037] (1) Insert one end of the motor shaft to be straightened into the left three-jaw chuck 53, operate the left three-jaw chuck 53 to clamp one end of the motor shaft, operate the linear module 11 to move the right three-jaw chuck 53 to the other end of the motor shaft, and operate the right three-jaw chuck 53 to clamp the other end of the motor shaft;

[0038] (2) Operate the dual-axis cylinder 23 to move the vertical plate 31 and the mounting plate 41 relative to each other until the baffle 32 is tightly fitted with the outer peripheral wall of the motor shaft, and the light emitter 34 emits a photoelectric signal toward the outer peripheral wall of the motor shaft and the baffle 32;

[0040] (4) When the light receiver 33 does not receive the signal from the light emitter 34, it indicates that the outer peripheral wall of the current motor shaft is not deformed. The controller 7 operates the linear module 11 to move the detection mechanism 3 and the straightening mechanism 4 on the horizontal plate 2 horizontally until the detection mechanism 3 and the straightening mechanism 4 move to the rightmost end of the motor shaft.
