After rotors of different sizes are placed in the magnetizing cavity, the adjusting connecting rods are moved according to the different sizes, thereby abutting the rotor to complete the processing. After the adjusting connecting rods abut, the rotor can be positioned and fixed, and magnetization can be carried out at this time. After magnetization, the rotor can be taken out, which reduces the situation where the same magnetizing machine is difficult to adapt to different rotors and improves versatility.

[0034] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0035] A rotor magnetizer, such as Figure 1 and Figure 2 As shown, it includes a frame 1, on which a magnetizing body 2 is provided, and a magnetizing coil is embedded in the interior of the magnetizing body 2. A magnetizing cavity 21 is provided in the middle of the magnetizing body 2, and a plurality of adjusting links 22 are provided on the top of the magnetizing body 2. The adjusting links 22 are slidably connected to the magnetizing body 2. The frame 1 is also provided with a plurality of driving members corresponding to the adjusting links 22, and the driving members are used to push the adjusting links 22 toward the magnetizing cavity 21. In specific implementation, when magnetizing, the rotor needs to be placed in the magnetizing cavity 21. When a rotor of smaller size is placed, the rotor can be abutted by the adjusting links 22, thereby fixing the position of the rotor, so that magnetization can proceed normally, thereby improving versatility.

[0036] like Figure 1 and Figure 2 As shown, the adjusting links 22 are arranged at equal intervals around the magnetizing body 2. In specific implementation, four adjusting links 22 are provided in this application, and the four adjusting links 22 can respectively abut from four directions, thereby stably and evenly applying force to the rotor and improving the stability of the rotor during magnetization.

[0037] like Figure 1 and Figure 2 As shown, a guide groove 23 is provided on the top of the magnetized body 2 corresponding to the adjustment link 22, and the adjustment link 22 is slidably connected to the guide groove 23. In a specific implementation, both sides of the adjustment link 22 abut against the groove walls of the guide groove 23, reducing the deviation of the adjustment link 22 during the sliding process and improving the stability of the adjustment link 22 during movement.

[0038] like Figure 1 and Figure 2 As shown in the figure, a curved plate 221 is fixedly mounted on the end of the adjustment link 22 near the magnetization chamber 21. This curved plate 221 is used to abut the rotor. The lower portion of the curved plate 221 extends into the magnetization chamber 21. In practice, since the entire rotor, including the rotating shaft and the unmagnetized permanent magnets, is substantially circular, the curved plate 221 precisely aligns with the rotor for clamping, further improving rotor stability during clamping.

[0039] like Figure 1 and Figure 2 As shown, a mounting frame 3 is provided at the bottom of the frame 1. The driving member includes a double-headed cylinder 11, which is stacked and mounted on the mounting frame 3. A transmission rod 222 is provided between the double-headed cylinder 11 and the adjustment connecting rod 22. One end of the transmission rod 222 is fixedly connected to the piston rod of the double-headed cylinder 11, and the other end of the transmission rod 222 is fixedly connected to the adjustment connecting rod 22. A clearance groove 14 is provided on the frame 1 corresponding to the transmission rod 222, and the transmission rod 222 is slidably connected within the clearance groove 14. In a specific implementation, two double-headed cylinders 11 are provided and fixedly mounted on the mounting frame 3 in a stacked manner. In this embodiment, two double-headed cylinders 11 are provided, and the piston rods at both ends are fixedly connected to the corresponding transmission rod 222, which can precisely drive the adjustment connecting rods 22 on opposite sides to move synchronously and clamp the rotor synchronously.

[0040] like Figure 1 and Figure 2 As shown, upper and lower cylinders 4 are also installed on the underside of the mounting frame 3. The piston rods of the upper and lower cylinders 4 are connected to the mounting frame 3, and the upper and lower cylinders 4 are used to push the mounting frame 3 up and down. The frame body 1 is equipped with multiple support rods 12, which extend through the mounting frame 3 and are slidably connected to the support rods 12. In practice, the upper and lower cylinders 4 can push the mounting frame 3 up and down along the support rods 12. During this movement, the adjustment connecting rod 22 can also move up and down. If the rotor height varies, the adjustment connecting rod 22 can also adjust accordingly, further improving versatility.

[0041] like Figure 1 and Figure 2 As shown, the magnetizing body 2 is internally provided with a water cooling circuit, which does not interfere with the magnetizing coil. A water inlet hose 24 and a water outlet hose 25 are provided on the magnetizing body 2. One end of the water cooling circuit is connected to the water inlet hose 24, and the other end of the water cooling circuit is connected to the water outlet hose 25. The frame 1 is also provided with multiple slots 13, to which a mounting plate 131 is detachably connected. The mounting plate 131 has two holes 132 formed therein, through which the water outlet hose 25 and the water inlet hose 24 extend. In specific implementation, the magnetizing body 2 needs to be cooled by the water cooling circuit before magnetization. Magnetization can only be performed when the temperature is maintained at a certain value. Therefore, this method has a better cooling effect and further improves the efficiency of magnetization. Since the cooling water needs to be injected from an external device, the positions of multiple slots 13 are provided, and the position of the mounting plate 131 can be changed according to the device injecting the water, further improving versatility.

[0042] Working principle: Before magnetization, cooling water needs to be injected to cool the magnetization body 2, and then the rotor is placed in the magnetization cavity 21 and clamped by adjusting the connecting rod 22. Then, DC voltage is passed into the magnetization coil to complete the magnetization work.

[0043] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
