Technical Field

The invention relates to a weight-removing balancing machine, in particular to a high-precision laser automatic weight-removing balancing machine for a motor rotor.

Background

The dynamic balancer is used to measure the unbalance of rotor and correct the unbalance of rotor based on the measured result to reduce the vibration produced during rotation of rotor or the vibration acting on bearing to allowable range for reducing vibration, improving performance and raising product quality.

In high-speed miniature permanent magnet rotor motors, the dynamic balance of the rotor plays a crucial role. Due to various factors such as uneven materials or blank defects, errors generated in processing and assembly, even asymmetric geometric shapes existing in design and the like, when the rotor rotates, centrifugal inertia force generated by each tiny mass point on the rotor cannot be counteracted mutually, and the centrifugal inertia force acts on machinery and the foundation through a bearing to cause vibration, generate noise, accelerate bearing abrasion, shorten the service life of the machinery, and can cause destructive accidents in serious cases. For such a rotor, the conventional dynamic balance correction method generally uses a dynamic balancing machine to detect, marks the unbalanced radius angle position by the starting point of the color mark circumference on the rotor, and performs deduplication at the unbalanced radius angle position by means of milling, drilling, grinding and planing.

Traditional de-weighting modes such as milling, drilling, grinding and planing need to clamp a machined part firmly due to the high-speed rotation of the cutter and the requirement of machining stress, but the defects exist at present: the method has the advantages of difficult product clamping, difficult tool compensation programming control caused by abrasion after the tool is repeatedly used, difficult position feeding control during the processing of the tool, difficult positioning of the re-processing of two sides and difficult control of the initial position of the part of the tool contacted with the processing part. Therefore, after the weight removal is finished, the dynamic balance detection is required to be carried out again, then the equivalent weight removal is carried out again, and the two steps are repeated until the dynamic balance detection is qualified, so that the efficiency is low, and the cost is high. In addition, the traditional weight removing mode can not achieve a very accurate weight removing effect due to the limitation of the structure, burrs are not easy to clean after the weight of the product is removed, and the product possibly existing in the weight removing and clamping process of the product is damaged.
