Description

Technical Field

[0001] This utility model relates to the field of magnet processing technology, and in particular to an integrated device for processing and polishing micro magnets. Background Technology

[0002] Magnet processing refers to a series of treatments and operations performed on magnetic materials to create magnet products with specific shapes, sizes, properties, and uses. To meet the final size and precision requirements of magnets, mechanical processing, such as cutting, grinding, and polishing, is often required after sintering.

[0003] In existing magnet processing technology, the cut magnet has at least two cut surfaces, so each cut surface needs to be polished, which is time-consuming and reduces processing efficiency. In view of this, we propose an integrated device for micro magnet processing and polishing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an integrated device for processing and polishing micro magnets. This device solves the technical problem that in the current magnet processing technology, the cut magnets have at least two cut surfaces, so each cut surface needs to be polished, which is time-consuming and reduces processing efficiency.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design an integrated device for processing and polishing micro magnets, including a machine tool, a transmission component on the surface of the machine tool, a worktable on one side of the transmission component, a polishing component in the middle of the worktable, a set of limiting mechanisms symmetrically arranged on the surface of the worktable, a micro magnet body sandwiched between the set of limiting mechanisms, and the micro magnet body in the cut state.

[0006] The polishing assembly includes a limiting groove, which is located on the inner side of the middle of the worktable. A lead screw is mounted through the limiting groove, and a motor is connected to the end of the lead screw. A positioning frame is provided on the outside of the motor. A movable frame is fitted on the surface of the lead screw, and a ceramic polishing plate is provided on the top of the movable frame. A protective plate is connected to one side of the ceramic polishing plate.

[0007] Preferably, the movable frame is threadedly connected to the lead screw, and the movable frame is fixedly connected to the ceramic grinding plate.

[0008] Preferably, the ceramic grinding plate and the protective plate are integrally formed, and the combination of the ceramic grinding plate and the protective plate can match and cover the top opening of the limiting groove.

[0009] Preferably, the limiting mechanism includes a fixed plate, which is fixed to the surface of the workbench. A set of electric push rods are symmetrically arranged on the surface of the fixed plate. The movable end of the electric push rod is connected to a bracket. A limiting frame is fixed to the end of the bracket. An electromagnet adsorption plate is embedded in the bottom inner side of the limiting frame.

[0010] Preferably, the limiting frame is a telescopic structure consisting of a bracket, an electric push rod, and a fixing plate, and the limiting frame is L-shaped.

[0011] Preferably, the limiting frame is made of permalloy material, and the micro magnet body is clamped between a set of limiting frames.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model effectively drives the lead screw to rotate via a motor, thereby causing the movable frame on the surface of the lead screw to move horizontally. When the ceramic grinding plate at the top of the movable frame comes into contact with the cut surface of the micro magnet body over a large area, the motor starts to rotate in both directions, causing the ceramic grinding plate to move back and forth on the cut surface of the micro magnet body, realizing rapid grinding of the cut surface of the micro magnet body and improving processing efficiency. The protective plate can effectively block the top opening of the limiting groove, preventing the waste from grinding the micro magnet body from falling into the limiting groove and damaging the lead screw.

[0014] 2. This utility model effectively moves the support frame by using an electric push rod, thereby enabling a set of limiting frames to effectively limit and clamp the micro magnet body to be polished, ensuring that the sides of both micro magnets are in contact with the limiting frames, facilitating the smooth entry of the ceramic polishing plate between the two micro magnets. Then, the electromagnet adsorption plates are energized, allowing a set of electromagnet adsorption plates to adsorb and fix the two micro magnets respectively, preventing the micro magnets from falling off due to uneven force. The limiting frames made of permalloy material can effectively reduce electromagnetic interference. Finally, the electric push rod moves the support frame and the limiting frames, causing the two micro magnets to separate, facilitating the subsequent polishing by the ceramic polishing plate.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Integrated device for processing and polishing miniature magnets, see [link / reference] Figures 1 to 4 The machine tool 1 includes a transmission component 2 on its surface, a worktable 3 on one side of the transmission component 2, a grinding component 4 in the middle of the worktable 3, a set of limiting mechanisms 5 symmetrically arranged on the surface of the worktable 3, and a micro magnet body 6 sandwiched between the set of limiting mechanisms 5. The micro magnet body 6 is in the state after cutting.

[0024] The grinding assembly 4 includes a limiting groove 401, which is located on the inner side of the middle of the worktable 3. A lead screw 402 is mounted through the limiting groove 401, and a motor 403 is connected to the end of the lead screw 402. A positioning frame 404 is provided on the outside of the motor 403. A movable frame 405 is fitted on the surface of the lead screw 402, and a ceramic grinding plate 406 is provided on the top of the movable frame 405. The movable frame 405 and the lead screw 402 are connected by threads, and the movable frame 405 and the ceramic grinding plate 406 are fixedly connected. A protective plate 407 is connected to one side of the ceramic grinding plate 406. Furthermore, the ceramic grinding plate 406 and the protective plate 407 are integrally formed. The combination of the ceramic grinding plate 406 and the protective plate 407 can match and cover the top opening of the limiting groove 401. This invention effectively drives the lead screw 402 to rotate via the motor 403, thereby causing the movable frame 405 on the surface of the lead screw 402 to translate. When the ceramic grinding plate 406 on the top of the movable frame 405 comes into contact with the cut surface of the micro magnet body 6 over a large area, the motor 403 starts to rotate in both directions, causing the ceramic grinding plate 406 to move back and forth at the cut surface of the micro magnet body 6, realizing rapid grinding of the cut surface of the micro magnet body 6 and improving processing efficiency. The protective plate 407 can effectively block the top opening of the limiting groove 401, preventing the waste from grinding the micro magnet body 6 from falling into the limiting groove 401 and damaging the lead screw 402.

[0025] It is worth noting that the limiting mechanism 5 includes a fixed plate 501, which is fixed to the surface of the workbench 3. A set of electric push rods 502 are symmetrically arranged on the surface of the fixed plate 501. The movable end of the electric push rod 502 is connected to a bracket 503. The end of the bracket 503 is fixedly connected to a limiting frame 504. The limiting frame 504 forms a telescopic structure with the bracket 503, the electric push rod 502 and the fixed plate 501. The limiting frame 504 is L-shaped. Furthermore, the limiting frame 504 is made of permalloy material. The micro magnet body 6 is sandwiched between a set of limiting frames 504. An electromagnet adsorption plate 505 is embedded on the inner side of the bottom of the limiting frame 504. This invention effectively moves the support 503 via an electric push rod 502, thereby allowing a set of limiting frames 504 to effectively limit and clamp the micro magnet body 6 to be polished, ensuring that the sides of both micro magnets are in contact with the limiting frames 504. This facilitates the smooth entry of the ceramic polishing plate 406 between the two micro magnets. Then, the electromagnet adsorption plate 505 is energized, allowing the set of electromagnet adsorption plates 505 to adsorb and fix the two micro magnets respectively, preventing the micro magnets from falling due to uneven force. The limiting frames 504, made of permalloy, can effectively reduce electromagnetic interference. Afterward, the electric push rod 502 moves the support 503 and the limiting frames 504, causing the two micro magnets to separate, facilitating the subsequent polishing by the ceramic polishing plate 406.

[0026] Working principle: The transmission component 2 transports the cut micro-magnet body 6 to a certain location. A person or a robot places the cut micro-magnet body 6 between a set of limiting frames 504. An electric push rod 502 moves the support 503, thereby allowing the limiting frames 504 to clamp and hold the micro-magnet body 6 to be polished, ensuring that the sides of both micro-magnet halves are in contact with the limiting frames 504. This facilitates the smooth entry of the ceramic grinding plate 406 between the two micro-magnet halves. Then, the electromagnet adsorption plates 505 are energized, allowing them to adsorb and fix the two micro-magnet halves separately, preventing uneven force on the micro-magnet blocks from causing them to fall. The limiting frames 504, made of permalloy, reduce electromagnetic interference. Then, the electric push rod 502 drives the bracket 503 and the limiting frame 504 to move, causing the two micro magnets to separate. At the same time, the motor 403 drives the lead screw 402 to rotate, thereby causing the movable frame 405 on the surface of the lead screw 402 to move horizontally. When the ceramic grinding plate 406 on the top of the movable frame 405 comes into contact with the cut surface of the micro magnet body 6 over a large area, the motor 403 starts to rotate in both directions, thereby causing the ceramic grinding plate 406 to move back and forth at the cut surface of the micro magnet body 6, realizing rapid grinding of the cut surface of the micro magnet body 6 and improving processing efficiency. The protective plate 407 can block the top opening of the limiting groove 401 to prevent the waste from grinding the micro magnet body 6 from falling into the limiting groove 401 and damaging the lead screw 402.
