Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, and more particularly to a tooling for assembling magnets. Background Technology

[0002] The magnets in a permanent magnet motor are one of the key components that generate the motor's magnetic field. They can generate a stable magnetic field that does not change over time, thus enabling the motor to operate normally. Generally, when assembling magnets on the rotor, workers manually insert the corresponding magnet pieces one by one into the magnet slots. When assembling the last magnet, the repulsion between the magnets is too great, making manual assembly impossible, and tooling is required for assistance.

[0003] Chinese patent CN214186072U discloses a rotor magnet assembly device for a radial motor. This device includes a guiding mechanism, a feeding mechanism, and a pushing mechanism. The guiding mechanism is located between the stator core and the pushing mechanism. The feeding mechanism is used to transport magnets to the guiding mechanism. A connecting piece is connected to a rotating device, which drives the stator core to rotate, causing the guiding mechanism to align with multiple magnet slots one by one. The pushing mechanism then pushes the magnets to move and engage them in the magnet slots. However, when installing a more precise rotor, the gap between the tooling and the magnets is small. During assembly, a certain amount of air and adhesive exists between the magnets in the tooling and the magnets in the rotor. The feeding mechanism of this device cannot guide this, which affects the assembly accuracy of the magnets.

[0004] Therefore, it is necessary to develop a tooling for assembling magnets to solve the above problems. Utility Model Content

[0012] Furthermore, the venting groove is formed by an inward recess from the lower end face of the pressure plate, and there is a pair of venting grooves, each corresponding to the second venting and glue discharge groove.

[0013] Furthermore, the exhaust groove is recessed inward from the side surface of the pressure plate of the plate body, and there is a pair of exhaust grooves, which correspond to the second exhaust and glue discharge groove respectively.

[0014] Furthermore, the venting groove of the pressure plate and the venting and adhesive discharge groove of the fixing member are located on the same side.

[0015] Furthermore, the pressure plate is made of aluminum.

[0016] Furthermore, the top of the pressure plate is provided with a lifting threaded hole, which is recessed inward from the top end face of the pressure plate.

[0017] Furthermore, the bottom of the fastener is provided with a connecting part, one side of which is fixedly connected to the body, and the other side extends horizontally outward. The connecting part has a connecting hole that penetrates its upper and lower surfaces.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is a tooling for assembling magnets, which has the characteristics of high assembly accuracy.

When the fastener 1 and the pressure plate 2 are assembled, the exhaust groove 22 of the pressure plate 2 and the exhaust and glue discharge groove 15 of the fastener 1 are located on the same side.

[0033] When using the tooling for assembling magnets according to this utility model, the fixing part 1 is fixedly connected to the rotor through the connecting hole 14 by bolts or screws, so that the assembly port 12 corresponds to the magnet assembly hole of the rotor. The magnet is put into the assembly port 12, and the pressure plate 2 is fixed and moved by the handling tool. The pressure plate 2 is moved above the magnet, and its end extends into the assembly port 12. The handling tool is disconnected from the pressure plate 2, and then the pressure plate 2 is slowly pushed by the hydraulic press so that the pressure plate 2 enters the assembly port 12 and presses the magnet. At the same time, the air and adhesive between the magnets are discharged through the exhaust and adhesive discharge groove 15. After the magnet is in place, the pressure plate 2 is removed, the fixing part 1 is disassembled, and the installation of the magnet is completed.

[0034] This utility model is a tooling for assembling magnets, which features high assembly precision. By slowly pushing the pressure plate into the assembly opening, the pressure plate is pressed against the magnet. At the same time, the air and adhesive between the magnets are discharged through the exhaust and adhesive discharge groove, thereby improving the assembly precision of the magnets.
