Description

Technical Field

[0002] The strength of a magnet generally refers to its ability to resist external forces. Surface treatment devices used to enhance the strength of magnets involve placing the magnet in the working area of ​​a magnetic grinder and precisely controlling the magnitude, direction, and frequency of the magnetic force to allow magnetic abrasive particles to perform all-around grinding on the magnet surface. This grinding method can remove minor protrusions, burrs, oxide layers, and other defects from the magnet surface, thereby optimizing the magnet surface.

[0003] Most existing surface treatment devices fix magnets in a unidirectional manner. Since different magnets have different sizes, if the fixing structure of the device is not easy to adjust, it means that the device may not be able to adapt to magnets of different shapes and sizes. This will result in some magnets not being effectively treated, thus affecting the improvement of their strength and limiting the scope of application of the device, thereby reducing its market competitiveness.

[0024] Please see Figures 2-3 In this embodiment, a strip-shaped groove 101 is provided on each of the two sides of the upper edge of the operating table 1. A grinding table 102 is installed in the middle of the upper end of the operating table 1. A rectangular groove 103 is provided at each corner of the upper part of the grinding table 102. A circular telescopic column 104 is inserted through the middle of the grinding table 102. The strip-shaped groove 101 facilitates the lateral movement of the grinding head 312. The rectangular groove 103 facilitates the retraction of the arc-shaped telescopic sleeve 201. A circular telescopic sleeve 105 is fitted on the outside of the circular telescopic column 104. The circular telescopic sleeve 105 passes through the operating table 1 and is fixedly connected to it. A first cylinder 106 is installed at the lower end of the circular telescopic sleeve 105. When one side of the magnet is ground, the circular telescopic column 104 pushes the magnet upward along the circular telescopic sleeve 105 through the drive of the first cylinder 106, making it convenient for the operator to flip the magnet over and continue grinding.

[0025] Please see Figure 4 In this embodiment, the positioning pin 203 passes through the arc-shaped telescopic sleeve 201 and is positioned and connected to the arc-shaped telescopic plate 202 through the positioning hole 204. After confirming that there is no problem, the first motor 208 is stopped. Then, the positioning pin 203 is picked up and passed through the arc-shaped telescopic sleeve 201 and is positioned and connected to the arc-shaped telescopic plate 202 through the positioning hole 204 for further reinforcement. An arc-shaped rubber pad 205 is installed on the inner side of the arc-shaped telescopic sleeve 201. The first threaded rod 207 is obliquely arranged along the rectangular slide groove 103. Driven by the first motor 208 and adjusted by the positioning pin 203, the first threaded rod 207 rotates, causing the rectangular threaded sleeve 206 to drive the arc-shaped telescopic sleeve 201 to move along the rectangular slide groove 103. At the same time, the arc-shaped telescopic plate 202 retracts and adjusts along the arc-shaped telescopic sleeve 201 until the arc-shaped rubber pad 205 approaches the magnet and is limited and fixed.

[0026] Please see Figures 5-6In this embodiment, the grinding assembly includes a support column 301, a strip-shaped threaded sleeve 302, a second threaded rod 303, a second motor 304, a rectangular telescopic sleeve 305, a second cylinder 306, a rectangular telescopic column 307, a connecting shaft 308, a third motor 309, a mounting block 310, a snap-fit ​​groove 311, a grinding head 312, a stud 313, and a nut 314. A strip-shaped threaded sleeve 302 is installed at the lower end of the support column 301, and a second threaded rod 303 passes through the middle of the strip-shaped threaded sleeve 302. The second threaded rod 303 extends along... The strip groove 101 is arranged laterally. A second motor 304 is installed at one end of the second threaded rod 303. A rectangular telescopic sleeve 305 is installed at the upper end of the support column 301. A second cylinder 306 is installed at one end of the rectangular telescopic sleeve 305. A rectangular telescopic column 307 is fitted inside the rectangular telescopic sleeve 305. After the magnet is fixed, according to the position that needs to be treated on its surface, the second threaded rod 303 is rotated by the drive of the second motor 304, so that the strip threaded sleeve 302 drives the support column 301 to move laterally along the strip groove 101. Once moved to the appropriate position, the rectangular telescopic column 307 is then driven by the second cylinder 306 to move longitudinally along the rectangular telescopic sleeve 305 to the appropriate position. A connecting shaft 308 is transversely inserted through the end of the rectangular telescopic column 307 away from the rectangular telescopic sleeve 305. A third motor 309 is mounted on one side of the connecting shaft 308. A mounting block 310 is provided at the end of the rectangular telescopic column 307 away from the rectangular telescopic sleeve 305. The mounting block 310 is rotatably connected to the rectangular telescopic column 307 via the connecting shaft 308. A snap-fit ​​groove 311 is provided on one side of the mounting block 310. A grinding head 312 is provided on the side of the mounting block 310 away from the rectangular telescopic column 307. The grinding head 312 is positioned and connected to the mounting block 310 through the snap-fit ​​groove 311. A stud 313 is inserted through the middle of the mounting block 310. Nuts 314 are fitted on the outside of each end of the stud 313. After the grinding head 312 has been used for a period of time, the nuts 314 can be loosened to remove the grinding head 312 for inspection or replacement. Then, the grinding head 312 is positioned and connected to the mounting block 310 through the snap-fit ​​groove 311. The stud 313 is then passed through the mounting block 310 and the grinding head 312, and the nuts 314 are tightened for continued use.

[0027] During the operation, the magnet to be surface treated is first placed on the grinding table 102. Then, according to the size of the magnet, the first threaded rod 207 is rotated by the drive of the first motor 208 and the adjustment of the positioning pin 203. This causes the rectangular threaded sleeve 206 to drive the arc-shaped telescopic sleeve 201 to move along the rectangular slide groove 103. At the same time, the arc-shaped telescopic plate 202 retracts and adjusts along the arc-shaped telescopic sleeve 201 until the arc-shaped rubber pad 205 comes close to the magnet and limits and fixes it. After confirming that there is no problem, the drive of the first motor 208 is stopped. Then, the positioning pin 203 is picked up and passed through the arc-shaped telescopic sleeve 201 and positioned and connected to the arc-shaped telescopic plate 202 through the positioning hole 204 for further reinforcement.

[0028] After the magnet is fixed, according to the position where its surface needs to be treated, the second threaded rod 303 is rotated by the second motor 304, so that the strip threaded sleeve 302 drives the support column 301 to move laterally along the strip groove 101 to the appropriate position. Then, driven by the second cylinder 306, the rectangular telescopic column 307 moves longitudinally along the rectangular telescopic sleeve 305 to the appropriate position. At the same time, driven by the third motor 309, the mounting block 310 rotates with the rectangular telescopic column 307 through the connecting shaft 308 to the appropriate angle. Then the grinding head 312 can start running.

[0029] After one side of the magnet is polished, driven by the first cylinder 106, the circular telescopic column 104 pushes the magnet upward along the circular telescopic sleeve 105, making it easy for the operator to flip the magnet over for further polishing. After the polishing head 312 has been used for a period of time, the nut 314 can be loosened to remove the polishing head 312 for inspection or replacement. Then, the polishing head 312 is positioned and connected to the mounting block 310 through the snap-fit ​​groove 311. Finally, the stud 313 is passed through the mounting block 310 and the polishing head 312, and the nut 314 is tightened for continued use.

[0030] Through the above steps, the magnet is placed on the grinding table on the operating table 1. The fixing component is adjusted and fixed according to the size of the magnet. Then, the surface of the magnet is treated by the grinding component. The adjustable fixing structure allows the operator to easily fix the magnet in the device and quickly adjust its position and posture, thereby simplifying the operation process, reducing the difficulty of operation, and adapting to magnets of different sizes. It eliminates the need for frequent replacement or adjustment of the device, improves the efficiency of surface treatment, expands the scope of application, and enhances its market competitiveness. This solves the problem that most existing surface treatment devices fix magnets in a unidirectional manner. Since different magnets have different sizes, some magnets may not be effectively treated, which may limit the scope of application of the equipment.
