It has a simple structure and is easy to use.

[0005] However, when the above magnetizing tool is actually used, during the magnetizing process of the motor, only the bottom end of the rotor is positioned, which may cause the angle of the rotor to deviate. At the same time, during the magnetizing process, the rotor may experience temperature increases, making it inconvenient to remove the rotor from the magnetizer, thereby affecting work efficiency.

[0009] By adopting the above technical solution, the rotor can be moved up and down inside the housing to avoid direct contact with the rotor, and at the same time, the bottom end shafts of rotors with different diameters can be quickly supported.

[0010] As a further description of the above technical solution: a plurality of sleeves are fixedly connected to the outer side of the top plate, and the plurality of sleeves are symmetrically arranged on the upper and lower sides of the top plate. A second spring is arranged inside the sleeve, and a movable block is fixedly connected to one side of the second spring. The outer side of the movable block is slidably connected to the inside of the second spring, and a positioning plate is fixedly connected to one side of the movable block. Three anti-slip strips are fixedly connected to the outer side of the positioning plate.

[0013] By adopting the above technical solution, the magnetized electrons are cooled to a certain extent, thereby avoiding excessively high temperature when the electrons are taken out.

[0014] The technical effects and advantages of this utility model are:

[0015] 1. By setting up a positioning mechanism, compared with the existing technology, the rotating shafts at the top and bottom of the rotor can be positioned fully and quickly, so that the rotor remains stable during the magnetization process, avoiding the rotor tilting during the magnetization process, and improving the efficiency and accuracy of the rotor magnetization;

[0025] The embodiment of the present application discloses a motor magnetization tooling structure, including a shell 1, the inner wall of the shell 1 is fixedly connected to two guide pillars 2, the two guide pillars 2 are symmetrically arranged inside the shell 1, and the outer side of the guide pillars 2 is movably connected to a positioning mechanism; the positioning mechanism includes two slides 3, the inner wall of the slide 3 is slidably connected to the outer side of the guide pillar 2, one side of the slide 3 is fixedly connected to a pull ring 4, one side of the two pull rings 4 is slidably connected to the outer side of the shell 1, the bottom of the slide 3 is fixedly connected to a bottom plate 5, the bottom of the bottom plate 5 is movably connected to a plurality of limiting rings 6, the bottom of the limiting ring 6 is movably connected to a plurality of first springs 7, and the bottom of the limiting ring 6 is fixedly connected to multiple A positioning rod 8, a first spring 7 is sleeved on the outside of the positioning rod 8, an anti-slip block 9 is fixedly connected to the bottom of the positioning rod 8, and two buffer pads 10 are fixedly connected to the top of the bottom plate 5; two slide grooves 11 are provided on the outside of the slide plate 3, a top plate 12 is movably connected to one side of the slide plate 3, and a plurality of sliders 13 are fixedly connected to the outside of the top plate 12, and the sliders 13 are slidably connected to the slide grooves 11. Pulling the pull ring 4 drives the slide plate 3 and the bottom base plate 5 to move up and down inside the shell 1, and the bottom rotating shaft of the rotor can be matched with the multiple limiting rings 6 on the top of the base plate 5 to press down, and the rotating shaft of the rotor can be limited to a certain position at the bottom of the base plate 5.

[0026] Reference Figure 5 As shown, a plurality of sleeves 14 are fixedly connected to the outside of the top plate 12, and the plurality of sleeves 14 are symmetrically arranged on the upper and lower sides of the top plate 12. A second spring 15 is arranged inside the sleeve 14, and a movable block 16 is fixedly connected to one side of the second spring 15. The movable block 16 is slidably connected inside the second spring 15, and a positioning plate 17 is fixedly connected to one side of the movable block 16. Three anti-slip strips 18 are fixedly connected to the outside of the positioning plate 17. The positioning plate 17 is driven by the plurality of movable blocks 16 to limit the top rotating shaft of the rotor, so that the rotor can remain vertical when placed inside the housing 1.

[0027] Reference Figure 1 and Figure 3 As shown, a heat dissipation mechanism is provided inside the shell 1, and the heat dissipation mechanism includes two fans 19. The outer sides of the two fans 19 are fixedly installed inside the shell 1, and the two fans 19 are symmetrically distributed inside the shell 1.

Then, the rotor is placed into the bottom of the shell 1 through the two pull rings 4, and the rotor is magnetized. After the rotor is magnetized, the pull ring 4 is pulled again to allow the rotor to move to one side of the two anti-slip strips 18. The position of the pull ring 4 is fixed by the pin. The two anti-slip strips 18 blow the heat on the surface of the rotor to one side of the water-cooling pipe 20, and the heat is absorbed to a certain extent by the water-cooling box 21 and the water-cooling pipe 20 to cool the rotor. Finally, the rotor is taken out from the inside of the shell 1.
