Description

TECHNICAL FIELD

[0001] The utility model belongs to permanent magnet motor production field, in particular, a kind of rotor positioning balancing machine for permanent magnet motor production. BACKGROUND

[0002] The working principle of the rotor positioning balancing machine is based on the theory of mechanical vibration and centrifugal force. When the motor rotor rotates, due to uneven mass distribution, centrifugal force is generated, resulting in vibration and noise. The balancing machine can accurately detect these unbalanced forces through the built-in sensor and measurement system, and convert them into electrical signals for analysis and processing. According to the measurement results, the balancing machine automatically calculates the mass that needs to be added or removed on the rotor, and corrects it at the corresponding position to achieve the dynamic balance of the rotor.

[0003] The Chinese patent with publication number CN221055952U discloses a positioning device for a rotor balancing machine. By rotating the movable frame, the fixed block at the front end of the movable frame and the lifting seat front end are engaged, and then the pin rod is used for fixation to realize the fixation of the movable frame. By rotating the knob to drive the screw rod to rotate, the lower end of the screw rod drives the adjusting block to slide down in the adjusting groove, and the lower end of the clamping wheel is attached to the surface of the rotating shaft to realize the clamping and fixation of the rotating shaft, increasing the stability of the rotor positioning. The transmission device drives the rotor to rotate, and the rotating shaft rotates between the support wheel and the clamping wheel. The support wheel and the clamping wheel rotate in coordination, and the vibration generated by the rotating shaft is transmitted to the shock-absorbing seat one and the shock-absorbing seat two, and then the shock-absorbing block one and the shock-absorbing block two buffer the vibration to realize the shock absorption of the rotor, while reducing the impact on other structures and increasing the overall service life of the device.

[0004] However, the support wheel and the clamping wheel of the above-mentioned patent can only clamp the rotor to rotate, and the rotor is prone to shaking when removing weight, lacking clamping and positioning, so a new device needs to be designed. UTILITY MODEL CONTENTS
