It is mainly used to increase the magnetic induction intensity of the electromagnet in electrical equipment. During the production process of the magnetic core, in order to improve the characteristics of the magnetic core after assembly and use, it is necessary to use a core section grinding device to grind the magnetic core to effectively remove these surface defects and make the core surface smoother. At the same time, the magnetic core can better adapt to various working environments and improve the stability and reliability of the equipment.

[0003] After searching, the Chinese patent application number 202022208848.7 discloses a grinding device for the production of high-stability and anti-interference transformer cores, including a grinding mechanism and a clamping mechanism.

[0042] The clamping structure 4 is arranged at the moving end of the bidirectional electric slide 9, wherein the clamping structure 4 includes a connecting seat 401 fixed to the moving end of the bidirectional electric slide 9, a first rotating block 403 rotatably connected inside the connecting seat 401, a second rotating block 404 rotatably connected inside the first rotating block 403, and a guide assembly arranged inside the connecting seat 401;

[0043] The second electric slide 8 is installed with the moving end of the first electric slide 7, and the moving end of the second electric slide 8 is installed with a hydraulic telescopic rod 10, the telescopic end of the hydraulic telescopic rod 10 is installed with a transmission motor 11, and the rotating end of the transmission motor 11 is detachably installed with a grinding wheel 12.

[0044] like Figure 1 , Figure 2 and Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the guide assembly includes a limit groove 405 opened in the connection seat 401, a moving block 406 detachably mounted on one side of the first rotating block 403 and sliding in the limit groove 405, and a slide rail 402 fixed on the outside of the first rotating block 403, a sliding structure is formed between the slide rail 402 and the connection seat 401, and the second rotating blocks 404 are evenly spaced inside one side of the first rotating block 403. By placing the magnetic core between the two groups of connection seats 401, a bidirectional electric slide 9 is used to push the first rotating block 403 and the magnetic core. The first rotating block 403 contacts the core, and then the first rotating block 403 is squeezed by the bidirectional electric slide 9 and the magnetic core and rotates in the connecting seat 401, adjusting the direction of the first rotating block 403. At the same time, the second rotating block 404 rotates inside the first rotating block 403, so that the second rotating block 404 fits tightly with the outer wall of the bidirectional electric slide 9, increasing the contact area between the device and the magnetic core, and is fixed in the position of the magnetic core.

[0048] The water pump 14 extracts the grinding liquid from the inside of the device through the outer shell 302. At the same time, the grinding liquid enters the inside of the filter cartridge 303 through the opening at the top of the outer shell 302. The grinding liquid is filtered by the filter cartridge 303, so that magnetic chips are accumulated inside the filter cartridge 303. The clean grinding liquid is sucked out by the water pump 14. At the same time, the magnetic force of the magnetic roller 304 is used to adsorb the magnetic chips, so that the magnetic chips are not easy to block the surface of the filter cartridge 303. The rotary cover 301 is rotated to separate the rotary cover 301 from the outer shell 302 through the thread, so as to facilitate the treatment of the magnetic chips on the surface of the magnetic roller 304.
