Then, the driving base 31 is slid towards the rotor 21, so that the connecting cylinder 33 is sleeved on the rotating shaft 211, the key teeth 331 are slid into the key grooves 214, and the output shaft of the motor 32 is coaxially connected with the rotating shaft 211. Then, the cutting base 41 is slid toward the rotor 21, so that the cutting blade 42 is close to the lower end of the weight plate 213. Then, the motor 32 is started to drive the rotor 21 to rotate, and if the rotor 21 is not balanced, i.e. the center of gravity is shifted, the bearing 22 is driven to rock in the bracket 2 during the rotation process, so that the sliding barrel 233 slides in the fixed barrel 231, and the counterweight plate 213 also rocks along with the rotor 21. Meanwhile, the measuring block 242 on the counterweight plate 213 slides away from the rotor 21 under the action of centrifugal force, and the measuring block 242 on the counterweight plate 213 which is greatly influenced by centrifugal force has the longest sliding distance. In the shaking process of the weight plate 213, a part of the weight plate 213 with a larger centrifugal force is shaken and cut by the cutting knife 42, and the weight of the weight plate 213 is reduced after the cutting knife 42 is used for cutting, so as to adjust the gravity center of the rotor 21 and correct the dynamic balance of the rotor 21. After calibration, the rotor 21 may be removed to determine whether the measurement block 242 with the farthest sliding distance corresponds to the cut portion of the weight plate 213. The whole process realizes synchronous detection and weight reduction seamless connection, and improves the correction efficiency of the dynamic balance of the rotor 21.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
