Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet motor rotor tooling, in particular to a permanent magnet motor rotor core manual magnetic steel glue-filling integrated tooling. Background Art

[0002] The glue pouring and magnet insertion of the rotor core directly affect the performance of the motor. If the rotor core magnet is inserted upside down or the epoxy resin enters between the silicon steel sheets, the product quality will be seriously affected. To complete this process using equipment, two devices are usually required, and the investment cost is high, the production capacity is excessive, and the equipment is idle. If the epoxy resin glue in the rotor slot is not full, it is easy to cause the magnet to loosen, and the motor will hit and break the magnet during high-speed rotation, which will directly affect the performance of the motor. Therefore, providing a manual magnet insertion and glue pouring integrated tooling can well solve the difficulties of prototypes and small batches, ensure product quality, and reduce manufacturing costs.

[0003] In other words, the existing technology mainly has the following defects: (1) It cannot meet the requirements of permanent magnet motor magnet steel filling, resulting in serious waste of raw materials and excessively high motor manufacturing costs; (2) The existing equipment has large investment, high cost, and overcapacity, and the special equipment has poor versatility, making it impossible to achieve small-batch production of prototypes.
