Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of correction mechanism accessory device, and particularly relates to a weight reduction structure for a balancing machine. BACKGROUND

[0002] The balancing machine is an instrument for measuring the unbalance of a rotor, and its working principle is based on the dynamic balance principle. It measures the unbalance of a rotating machine and takes appropriate correction measures to make the machine reach a balanced state, thereby improving the performance and reliability of the machine. The balancing machine belongs to a hard support balancing machine, has a large swing frame rigidity, and can correct the unbalance of the rotor by using the measurement result of the dynamic balancing machine, so that the vibration generated by the rotor during rotation or the vibration generated on the bearing is reduced to the allowable range, so as to achieve the purpose of reducing vibration, improving performance and improving product quality.

[0003] Rotor dynamic balancing correction equipment can be divided into two categories, namely manual correction dynamic balancing machine and full-automatic balancing correction equipment. The manual correction balancing machine has low cost, but the balancing process depends on the experience of workers, and the stability of balancing is difficult to guarantee. In comparison, the full-automatic balancing correction equipment has high production efficiency and high balancing stability, and can optimize the correction of the rotor, but the machine is relatively expensive. At present, with the development of the electrical machinery industry in China, it has become an inevitable trend to use full-automatic balancing correction equipment.

[0004] A lever feeding device for a full-automatic balancing correction equipment is disclosed in Chinese Patent No. CN207556752U, which comprises an upper plate and a lower plate. A lifting drive device is arranged on the upper plate, and the output shaft of the lifting drive device is connected with the lower plate through the upper plate. Two fixed seat bodies are arranged on the upper plate, and a shaft is arranged between the two fixed seat bodies. An active part is movably sleeved on the shaft, and the active part is fixedly connected with the lower plate. A through hole is arranged on the upper plate for the active part to swing relative to the fixed seat body along the shaft. A driving motor and a cutting spindle head are arranged on the upper plate, and the driving motor and the cutting spindle head transmit power through a transmission part. The utility model has compact structure, high positioning accuracy and high control resolution. However, during use, the output shaft of the lifting drive device inside the above-mentioned device will produce an angle with the horizontal plane after lifting, because the output shaft needs to be kept vertical at all times, and because the driving mechanism is fixedly connected with the upper plate, the output shaft will be stuck with the upper plate. It can be seen that during use, the angle and the transverse position cannot be flexibly adjusted, the overall adaptation ability is poor, and there are certain defects and deficiencies, so improvement is needed.
