[0024] A uniform rare earth permanent magnet magnetizing tool, such as Figure 1 As shown, it includes a base 10, a conveyor belt 11 movably installed on the top surface of the base 10 for conveying, and a magnetizing device is installed on the wall of the conveyor belt 11. Specifically, the magnetizing device includes a magnetizing head, and the magnetizing head includes a superconducting magnet and a superconducting coil arranged inside the superconducting magnet. After power is turned on, a magnetic field is generated to achieve mutual inductance magnetization of rare earth permanent magnetic materials. A plurality of rollers are provided on the wall of the base 10, and the conveyor belt 11 is wound around the surface of the rollers. A motor is also fixedly installed on the wall of the base 10, and the output shaft of the motor is fixedly connected to the roller. The specific model and specification are not limited too much here.
[0025] like Figure 2 , Figure 3As shown, the wall surface of the conveyor belt 11 is provided with a clamping structure for limiting the position of the rare earth permanent magnetic material, and the clamping structure includes a mounting block 20, a clamping portion 21, a clamping claw 22 and a contact plate 23. The wall surface of the conveyor belt 11 is rotatably connected to a plurality of mounting blocks 20, and the top of each mounting block 20 is fixedly connected to the same clamping portion 21, and two clamping claws 22 that can approach each other are symmetrically arranged on the top of each clamping portion 21, and the clamping claw 22 is elastically connected to the clamping portion 21, and the contact plate 23 is elastically connected to the base 10 and contacts the mounting block 20, and the mounting block 20 can be driven to rotate by the contact plate 23, and a bearing is installed on the bottom surface of the mounting block 20, and a plurality of plug rods are fixedly connected to the top surface of the conveyor belt 11 The insertion rod is fixedly connected to the inner ring of the bearing. In this solution, the contact plate 23 abuts against the mounting block 20. When the conveyor belt 11 drives the mounting block 20 to move linearly, the contact plate 23 and the mounting block 20 produce relative movement. The wall surface of the contact plate 23 close to the mounting block 20 is polished to form a rough surface. The circumferential surface of the mounting block 20 forms a rough contact surface. The mounting block 20 rotates to drive the clamping part 21 and the clamping jaw 22 to rotate, and the workpiece clamped and fixed by the two clamping jaws 22 rotates continuously during the linear movement of the conveyor belt 11, thereby continuously changing the angle of the workpiece, so that the workpiece can be turned over and keep uniform magnetization. The structure is simple and is conducive to actual production applications.
[0026] like Figure 3 , Figure 4 and Figure 5 As shown, the clamping portion 21 forms a U-shaped rod structure, the two clamping jaws 22 are located in the recess of the clamping portion 21, and a limiting channel 30 is provided on the inner bottom surface of the clamping portion 21.

The second elastic member pushes the contact plate 23 to fit closely with the mounting block 20, which can ensure that the contact plate 23 is in full contact with the mounting block 20, and then the mounting block 20 can be pushed by the contact plate 23 to keep rotating, thereby maintaining stable operation.
[0029] The working principle of the utility model is as follows: by installing a guide body 32 on the top surface of each clamping jaw 22, and using two guide bodies 32 distributed in an inner eight shape to form a guide channel, the workpiece can be guided by the two guide bodies 32 to enter between the two clamping jaws 22, so as to achieve the clamping and fixing of the workpiece, and the second elastic member pushes the contact plate 23 to fit closely with the mounting block 20, so as to ensure the full contact between the contact plate 23 and the mounting block 20, the wall surface of the contact plate 23 close to the mounting block 20 is polished to form a rough surface, and the circumferential surface of the mounting block 20 forms a rough contact surface, and the mounting block 20 is rotated to drive the clamping part 21 and the clamping jaw 22 to rotate, and the workpiece clamped and fixed by the two clamping jaws 22 rotates continuously during the linear movement of the conveyor belt 11, thereby continuously changing the angle of the workpiece, so that the workpiece can be turned over and kept uniformly magnetized, and the magnetizing device is energized to magnetize each workpiece.
