[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] In existing technologies, when grinding rare earth permanent magnet materials, to ensure the grinding effect, coarse grinding is generally performed first, followed by fine grinding. This requires frequent changes of grinding heads with different roughnesses, which is cumbersome and inconvenient. To address this technical deficiency in existing technologies, such as... Figures 1-4 As shown in the figure, this embodiment proposes a high-precision polishing device for rare earth permanent magnet materials, which can perform both coarse and fine polishing of rare earth permanent magnet materials. It has high integration and is easy to use. The device has a vertical mounting plate 2 fixedly installed on the processing base 1, and a workpiece 4 to be polished is placed on the processing base 1. The vertical mounting plate 2 is equipped with a polishing mechanism 3 for rapid polishing of the workpiece 4. The processing base 1 is equipped with a polishing auxiliary mechanism 5 for limiting and clamping the workpiece 4. After the operator places the workpiece 4 to be polished on the processing base 1, the polishing mechanism 3 will automatically perform coarse and fine polishing on the workpiece. During the process, the polishing auxiliary mechanism 5 will clamp and limit the workpiece.

[0023] Specifically, the grinding and polishing mechanism 3 includes a rotating circular seat 301 movably mounted on the mounting vertical plate 2. A drive assembly 302 is symmetrically mounted on the rotating circular seat 301. Each drive assembly 302 includes a mounting bracket detachably mounted on the rotating circular seat 301. A drive motor is fixedly mounted on the mounting bracket. When the drive motor is powered on, it causes the grinding head to rotate rapidly, thereby completing the grinding process. A first grinding head 303 and a second grinding head 304 are respectively mounted on the two drive assemblies 302. The roughness of the first grinding head 303 is greater than that of the second grinding head 304. The first grinding head 303 and the surface roughness of the surface roughness are... When the polishing workpiece 4 comes into contact, it will perform coarse grinding. When the second grinding head 304 comes into contact with the workpiece 4 to be polished, it will perform fine grinding. A drive motor 305 for driving the rotating seat 301 is fixedly installed on the mounting vertical plate 2. Two press-type storage tanks 306 are symmetrically arranged on both sides of the grinding auxiliary mechanism 5. When the rotating seat 301 rotates under the action of the drive motor 305, the grinding head will be quickly changed. The two press-type storage tanks 306 are filled with different polishing pastes. Before polishing, the staff can use the press-type storage tanks 306 to quickly take out the polishing paste.

[0024] To maximize the polishing effect and prevent workpiece displacement during polishing, this embodiment includes a polishing auxiliary mechanism 5. Specifically, the polishing auxiliary mechanism 5 includes a vertical push rod 502 fixedly mounted on the processing base 1. A polishing platform 501 is mounted on the vertical push rod 502. The polishing platform 501 has symmetrically arranged limit grooves 503. Each limit groove 503 is equipped with a movable clamping block 504. The inside of the limit groove 503 is equipped with a limit spring 505 that pushes the movable clamping block 504 to move. After the operator places the workpiece 4 to be polished on the polishing platform 501, the two movable clamping blocks 504 will automatically clamp and limit the workpiece. A telescopic sleeve 506 is detachably mounted on the processing base 1. The telescopic sleeve 506 is sleeved on the outside of the polishing platform 501. During polishing, the operator will pull the telescopic sleeve 506 upward to block the polishing area.

[0025] As can be seen from the above, during the polishing process, firstly, the worker will place the workpiece 4 to be polished on the upper end of the polishing platform 501. Next, the two movable clamping blocks 504 will automatically clamp and limit the workpiece 4 to be polished under the action of the limiting spring 505. Then, the worker will pull the telescopic sleeve 506 upward so that the telescopic sleeve 506 surrounds the outside of the polishing platform 501.

[0026] Next, the grinding platform 501 will move upward a certain distance under the action of the vertical push rod 502, so that the workpiece 4 to be polished comes into contact with the first grinding head 303. Then, the first grinding head 303 will rotate rapidly under the action of the drive assembly 302, thereby completing the rough grinding of the workpiece.

[0027] After rough grinding is completed, the rotating base 301 will rotate 180 degrees under the action of the drive motor 305, thereby exchanging the positions of the first grinding head 303 and the second grinding head 304. Next, the grinding platform 501 will contact the second grinding head 304 in the same way. Then, the second grinding head 304 will rotate rapidly under the action of the drive assembly 302, thereby completing the fine grinding of the workpiece.

[0028] Furthermore, during the grinding process, the telescopic sleeve 506 will shield the outside of the grinding platform 501, which can effectively prevent particles from splashing during the grinding process.

[0029] This embodiment, by setting up a grinding and polishing mechanism 3, utilizes the cooperation between the rotating round seat 301 and the drive motor 305 to automatically and quickly change the grinding head during the grinding and polishing process. It can perform both coarse and fine grinding on rare earth permanent magnet materials, with high integration and ease of use, eliminating the need for manual grinding head replacement by operators. Moreover, this embodiment, by setting up a grinding auxiliary mechanism 5, utilizes the cooperation between the movable clamping block 504 and the telescopic sleeve 506 to clamp and vertically transport the workpiece during the grinding process, which can improve the grinding effect and accuracy to a certain extent. In addition, it can shield and protect the grinding area, effectively preventing grinding debris from flying everywhere.

[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
