Abstract

The invention relates to a motor rotor dynamic balance correction device, which relates to the technical field of rotor dynamic balance and comprises a base and supports arranged at two ends of the base, elastic parts and bearings are arranged on the supports, the elastic parts are used for supporting the bearings, a rotor is arranged in the bearings in a penetrating manner, counterweight discs are arranged at two ends of a winding of the rotor, and a driving assembly for driving the rotor to rotate is arranged on the base. The base is further provided with a cutting assembly for conducting cutting and weight reduction on the balance weight disc. The bearing is arranged and supported by the elastic piece, so that the rotating rotor can shake under the elastic piece, the part, subjected to large centrifugal force, of the balance weight disc is made to be close to the cutting assembly to be cut, the redundant balance weight disc is cut, detection and weight reduction seamless connection are synchronously carried out, and the detection efficiency is improved. Therefore, the dynamic balance correction efficiency of the rotor is improved.

Description

technical field [0001] The present application relates to the technical field of rotor dynamic balance, and in particular, to a device for correcting rotor dynamic balance of a motor. Background technique [0002] At present, in the manufacturing process of the motor, due to the unevenness of the manufacturing material, the center of gravity of the rotor will be offset from the axis, causing vibration and wear of the motor during operation. Therefore, the rotor is dynamically balanced during the motor production process. [0003] The traditional dynamic balance correction is usually to measure the unbalanced position and unbalanced weight through the dynamic balance detector, and then use the method of increasing or reducing the weight after marking, such as riveting the washer on the rotor balance column or grinding the end face of the balance rotor to eliminate the problem. The center of gravity is shifted, and it needs to be tested again after the weight is applied to det...
