Technical Field

[0001] The utility model relates to the technical field of magnet processing, in particular to a grinding device for magnet processing. Background Technique

[0002] The components of a magnet are atoms such as iron, cobalt, and nickel. The internal structure of its atoms is relatively special and it itself has a magnetic moment. A magnet can generate a magnetic field and has the property of attracting ferromagnetic substances such as metals like iron, nickel, and cobalt. Types of magnets: Shape magnets: square magnets, tile magnets, special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, magnetic rod magnets, magnetic force frame magnets; Attribute magnets: samarium cobalt magnets, neodymium iron boron magnets (powerful magnets), ferrite magnets, alnico magnets, iron chromium cobalt magnets; Industry magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc. During the processing of magnets, grinding equipment is required for grinding.

[0003] A grinding and polishing device for electromagnet processing provided by the publication number "CN220740552U" includes a base. A horizontal driving mechanism is installed inside the base.

A support frame is installed at the top of the base. A lifting mechanism is installed inside the support frame. A translational mounting plate is installed on one side of the lifting mechanism. A first electric cylinder is installed at the bottom of the translational mounting plate. One end of the first electric cylinder is installed with a connecting rod. One end of the connecting rod is installed with an electric control rotating shaft. One end of the electric control rotating shaft is connected and installed with a grinding and polishing mechanism; This device can automatically clamp and flip the electromagnet, avoiding the need for manual flipping, grinding, and polishing by workers, which is rather inconvenient and time-consuming and laborious.

[0004] However, the following problems still exist during the implementation of the above device:

[0005] In the above solution, the placing table can be driven to move, so that when grinding and polishing the magnet, it is not necessary for workers to manually adjust the working position at all times, improving production efficiency. However, considering that the grinding equipment in the above solution lacks the function of clamping the magnet, the magnet on the placing table will shift during the moving grinding process, thus affecting the grinding effect.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 - Figure 6 , the present utility model provides a technical solution:

[0028] Embodiment 1:

[0029] A grinding device for magnet processing, including a base 1, a grinding machine 2 and a placing table 3. The grinding machine 2 is fixedly installed on the top of the base 1, the placing table 3 is drivingly connected to the top of the base 1, and a clamping mechanism is arranged on the top of the placing table 3;

[0030] The clamping mechanism includes two clamping blocks 4 located on the top of the placing table 3. An air collecting cavity 5 is opened inside the clamping block 4. A plurality of storage holes 6 are opened on the inner wall of the air collecting cavity 5. A pushing rod 7 is arranged inside the storage hole 6. One end of the pushing rod 7 is fixedly connected to a pushing block 8. One side of the pushing block 8 is fixedly connected to a piston 9. An electric telescopic rod 10 is fixedly installed at the bottom of the placing table 3. The output end of the electric telescopic rod 10 is fixedly connected to a transmission block 11. The top of the transmission block 11 is fixedly connected to the bottom of the clamping block 4. An air collecting mechanism is arranged on one side of the clamping block 4.

[0031] In this embodiment, considering that the grinding device lacks the function of clamping the magnet, during the moving grinding process of the magnet on the placing table 3, the magnet will shift, which will affect the grinding effect. Therefore, by setting the clamping mechanism, the magnet can be placed on the placing table 3, and then by starting the electric telescopic rod 10, the transmission block 11 and the clamping block 4 are driven to move, so that the two clamping blocks 4 clamp and fix the magnet, avoiding the magnet from shifting during the grinding process, and thus improving the grinding effect;

[0032] It solves the problem that considering that the grinding device lacks the function of clamping the magnet, during the moving grinding process of the magnet on the placing table 3, the magnet will shift, which will affect the grinding effect.

[0033] One side of the pushing block 8 is fixedly connected to a spring 21. One end of the spring 21 is fixedly connected to the inner wall of the storage hole 6.

[0034] In this embodiment, by setting the spring 21, when the pressure relief pipe 25 is opened and the gas in the air collecting cavity 5 is discharged through the pressure relief pipe 25, the reaction force generated by the spring 21 will push the mechanism of the pushing block 8 and the pushing rod 7 to move, playing a role of resetting.

[0035] One end of the abutting rod 7 is fixedly connected with a spherical block 22 , and the material of the spherical block 22 is rubber.

[0036] In this embodiment, by providing the spherical block 22, when the abutting rod 7 is moved by the air pressure to contact the magnet, the spherical block 22 can play a buffering role, thereby further improving the stability of clamping.

[0037] Both sides of the bottom of the clamping block 4 are fixedly connected with sliding blocks 23 , and the top of the storage platform 3 is provided with a sliding groove 24 used in conjunction with the sliding block 23 .

[0038] In this embodiment, by providing the sliding block 23 and the sliding groove 24, the stability of the clamping block 4 during movement can be improved, thereby improving the clamping effect.

[0039] Embodiment 2:

[0040] On the basis of the first embodiment, the clamping mechanism in the present embodiment can clamp and fix the magnet to avoid the phenomenon of displacement of the magnet during the grinding process, thereby improving the grinding effect. However, considering that many magnets are of special shapes, the clamping block 4 can hardly fully contact with the surface of the magnet for clamping, which will also reduce the stability of the clamping. The gas collecting mechanism in the present application includes an air collecting box 12 fixedly mounted on one side of the clamping block 4, the top of the air collecting box 12 is fixedly connected to a transmission pipe 13 through a first one-way valve, the transmission pipe 13 is fixedly connected to the air collecting chamber 5, one side of the air collecting box 12 is fixedly connected to an air inlet pipe 14 through a second one-way valve, a push block 15 is arranged inside the air collecting box 12, one side of the push block 15 is fixedly connected to a push rod 16, and one side of the clamping block 4 is fixedly connected to a pressure relief pipe 25 through an electromagnetic valve;

[0041] The gas collecting mechanism also includes a motor 17 fixedly connected to the top of the gas collecting box 12, the output end of the motor 17 is fixedly connected to a screw rod 18, the surface of the screw rod 18 is transmission-connected to a moving block 19, and one end of the push rod 16 passes through the outside of the gas collecting box 12 and is fixedly connected to one side of the moving block 19.

[0042] In this embodiment, considering that many magnets are of irregular shapes, the clamping block 4 can hardly fully contact the surface of the magnet for clamping, which will also reduce the stability of the clamping. Therefore, by setting an air collecting mechanism, after the clamping block 4 contacts the magnet, the motor 17 is started to drive the screw rod 18 to rotate. During the rotation of the screw rod 18, the moving block 19 is transmitted to make the moving block 19 reciprocate. Figure 3As shown in the figure, when the moving block 19 moves to the left, it will drive the push rod 16, the push block 15 and the sealing block 20 to move to the left. At this time, the inside of the air collecting box 12 is in negative pressure, and the gas will enter the air collecting box 12 from the air inlet pipe 14. When the moving block 19 moves to the right, it will drive the push rod 16, the push block 15 and the sealing block 20 to move to the right, compressing the gas in the air collecting box 12 into the air collecting cavity 5. The compressed gas in the air collecting cavity 5 is cycled in turn. Under the influence of air pressure, the piston 9 will be pushed, driving the abutting block 8, the abutting rod 7 and the spherical block 22 to move. Finally, the spherical block 22 can be in contact with the special-shaped part of the magnet surface, which can effectively improve the clamping stability and further improve the grinding effect;

[0043] It solves the problem that considering many magnets are special-shaped, the clamping block 4 is very difficult to fully contact the magnet surface for clamping, which will also reduce the clamping stability;

[0044] It should be noted that the first one-way valve is a valve that can only let air into the air collecting cavity 5, and the second one-way valve is a valve that can only let air into the air collecting box 12. When it is necessary to release the clamping and fix, start the solenoid valve, and the gas will be discharged from the pressure relief pipe 25. Affected by the elastic force generated by the spring 21, the abutting rod 7 and other structures will also reset and spring back into the storage hole 6.

[0045] Preferably, one side of the push block 15 is fixedly connected with a sealing block 20, and the material of the sealing block 20 is rubber.

[0046] In this embodiment, by setting the sealing block 20, a sealed cavity can be formed inside the air collecting box 12. When the sealing block 20 moves, it can push the gas in the air collecting box 12 to enter the air collecting cavity 5.

[0047] Working principle: The user places the magnet on the placement table 3, and then starts the electric telescopic rod 10 to drive the transmission block 11 and the clamping block 4 to move, so that the two clamping blocks 4 clamp and fix the magnet;

[0048] After that, start the motor 17 to drive the lead screw 18 to rotate. During the rotation of the lead screw 18, it will drive the moving block 19 to move, so that the moving block 19 moves reciprocally, as Figure 3As shown, when the moving block 19 moves to the left, it will drive the push rod 16, the push block 15 and the sealing block 20 to move to the left. At this time, the inside of the air collecting box 12 is in negative pressure, and the gas will enter the air collecting box 12 from the air inlet pipe 14. When the moving block 19 moves to the right, it will drive the push rod 16, the push block 15 and the sealing block 20 to move to the right, compressing the gas in the air collecting box 12 into the air collecting cavity 5. By circulating in this way, the gas is compressed into the air collecting cavity 5. Under the influence of air pressure, the piston 9 will be pushed, driving the abutting block 8, the abutting rod 7 and the spherical block 22 to move. Eventually, the spherical block 22 contacts the special-shaped part of the magnet surface, which can effectively improve the clamping stability and further improve the grinding effect.

[0049] It should be noted that the electric telescopic rod 10, the solenoid valve and the motor 17 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. And the specific composition and principle of the power supply of the electric telescopic rod 10, the solenoid valve and the motor 17 are clear to those skilled in the art, so no further detailed description will be given.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
