Description

Technical Field

[0001] This invention relates to the field of cylindrical magnet surface polishing technology, specifically to a surface polishing device for magnet processing. Background Technology

[0002] Surface grinding of magnets involves precision grinding of the outer surface of cylindrical magnets after the magnet forming process. This ensures that the dimensions of the cylindrical outer surface are compliant with regulations. It also allows for secondary rework of the outer surface of cylindrical magnets after random sampling inspection, guaranteeing the dimensional specifications of the produced magnets. This prevents burrs, stubborn impurities, dirt, and non-compliant irregular dimensions from remaining on the surface of the magnets after forming, which would affect the output and quality of the finished magnets.

[0003] Existing magnet surface grinding processes generally employ grinding rollers. During the rotation of a cylindrical magnet driven by clamping and external force, the outer surface of the magnet is ground, forming a cylindrical component that meets the manufacturing requirements and dimensional specifications. The grinding effect is achieved through damping and contact friction. The use of roller grinding components is efficient because they can closely conform to the cylindrical magnet component, significantly accelerating the grinding process. However, this process, especially for reworked magnets, suffers from several drawbacks. Because reworked and finely ground magnets retain magnetism, waste material is often adsorbed onto the outer surface during grinding, affecting grinding efficiency. Furthermore, the adsorption of waste material can lead to irregularities and defects in the magnet's external surface due to the grinding process.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing magnet surface polishing techniques. Summary of the Invention

[0005] The purpose of this invention is to provide a surface polishing device for magnet processing, in order to solve the problems mentioned in the background art, where existing magnet surface polishing processes leave adsorbed waste material on the magnet during the polishing process, and the storage of waste material affects the efficiency of magnet polishing and easily leads to defects.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface polishing device for magnet processing, comprising a conveyor table and a conveyor roller on it for guiding the movement of cylindrical magnets, as well as a lifting seat in the middle of the conveyor table and a clamping head for clamping the cylindrical magnets; It also includes: a clamping head, which moves vertically up and down and axially across the conveyor table, and clamps the cylindrical magnet with axial pressure at its end; The waste collection chamber is symmetrically installed above the clamping head on the conveyor table. The waste collection chamber is also equipped with a blocking brush at the waste inlet and a fixing plate on the outside of the waste collection chamber. The movable platform is installed in the middle of the fixed plate. A grinding seat is also installed through the movable platform. The grinding seat has a retractable grinding component in the middle of the front side. The front edge of the grinding seat has an airbag belt and a waste collection channel. The airbag belt and waste collection channel are used to push and discharge waste on the cylindrical magnet.

[0007] Preferably, the lifting seat is driven by a hydraulic component on the outside of the conveying table to control its lifting displacement and positioning. At the same time, a motor screw assembly is fixed on the top of the lifting seat. A movable seat is movably installed on the outside of the screw of the motor screw assembly. A drive motor is fixed on the movable seat, and the drive motor drives the clamping head at the end of its output shaft to rotate.

[0008] Preferably, there are two clamping heads symmetrically distributed about the transverse central axis of the conveyor table. The clamping heads move laterally and rotate along their own central axis to drive the positioning and rotational movement control of the cylindrical magnets clamped between adjacent clamping heads.

[0009] Preferably, the waste collection chamber is installed symmetrically, wherein the waste collection chamber is connected to the pump body through a pipeline, and the barrier brushes between adjacent waste collection chambers are cross-distributed, the barrier brushes prevent waste from falling and clean the waste on the outside of the cylindrical magnet.

[0010] Preferably, the movable table moves laterally via hydraulic guide rails fixed on the fixed plate, wherein the movable table and the grinding seat form a relatively telescopic structure, and the grinding seat is driven to telescopically move by a motor drive assembly on the movable table.

[0011] Preferably, the grinding component, airbag belt, and grinding base are all configured with an arc-shaped structure, wherein the grinding component is driven to extend, retract, and be positioned by an electromagnetic component in the middle of the grinding base; The back of the grinding base is connected to an external pump via a pipe.

[0012] Preferably, the grinding seat is attached to the outside of the cylindrical magnet and is used for grinding the outer cylindrical surface of the cylindrical magnet while it is rotating; at the same time, the outer side of the airbag belt is provided with a wear-resistant layer for damping the pushing of waste material on the outside of the cylindrical magnet.

[0013] Preferably, the exhaust pipe is rotatably installed on the left and right sides of the grinding seat, wherein a waste gas collection bag is fixed on the outside of the exhaust pipe, and the exhaust pipe, the waste gas collection bag, the waste collection channel and the air bag belt are arranged in a one-to-one correspondence. During rotation, the waste gas collection bag and the air bag belt realize the kneading and removal of waste material on the outside of the cylindrical magnet.

[0014] Preferably, the exhaust pipe is driven to rotate by airflow, and an exhaust port is provided in the middle of the exhaust pipe. The exhaust port and the waste collection channel work together to remove the waste generated by grinding the cylindrical magnet.

[0015] Preferably, the upper port of the exhaust pipe is also rotatably mounted with an air guide pipe via a sealed bearing, and a turbine blade is also fixed inside the upper port of the exhaust pipe, which is driven to rotate by airflow.

The specific details are as follows: 1. By combining the grinding base and grinding parts, the grinding parts move alternately during grinding, and process the surface of the magnet to be ground in sections. The airbag belt is pressed against the outer surface of the magnet to be ground, and the adhesive waste generated during grinding is pushed to the waste collection channel for waste discharge. 2. Furthermore, an exhaust pipe and a waste gas collection bag driven by airflow are also provided. Driven by airflow, the exhaust pipe and the waste gas collection bag rotate synchronously, causing the waste gas collection bag to rotate repeatedly and exert damping and squeezing effects with the air bag belt. Under the contact deformation and pressure of the two, the impurities adhering to the outer surface of the magnet are discharged from the columnar magnet in a kneading manner, thereby avoiding the waste from being difficult to discharge due to adhesion. 3. The exhaust pipe driven by airflow can also push the waste material to the location of the waste collection channel during the kneading and waste removal process, thereby effectively improving the waste removal efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-11 The present invention provides a technical solution: a surface grinding device for magnet processing, comprising a conveyor table 1 and a conveyor roller 2 on it for guiding the movement of cylindrical magnets, a lifting seat 3 in the middle of the conveyor table 1 and a clamping head 4 for clamping the cylindrical magnets; the clamping head 4 performs vertical lifting and axial lateral movement on the conveyor table 1, and the clamping head 4 applies axial pressure to clamp the ends of the cylindrical magnets; In the above scheme, the lifting seat 3 is driven by the hydraulic component 301 on the outside of the conveyor table 1 to control its lifting displacement and positioning. At the same time, a motor screw assembly 401 is fixed on the top of the lifting seat 3. A movable seat 403 is movably installed on the outside of the screw of the motor screw assembly 401. A drive motor 402 is fixed on the movable seat 403. The drive motor 402 drives the clamping head 4 at the end of its output shaft to rotate. There are two clamping heads 4 symmetrically distributed about the transverse central axis of the conveyor table 1. The clamping heads 4 move laterally and rotate around their own central axis to drive the positioning and rotation movement control of the cylindrical magnets clamped between adjacent clamping heads 4.

[0021] Based on the above technical solution, the combined use of the conveying roller 2 and the conveying table 1 enables the cylindrical magnet to move on the conveying table 1. Since the conveying roller 2 is driven by a motor and has protrusions on its exterior, it can stably convey the cylindrical magnet when rotating. Furthermore, because the outer surface of the conveying roller 2 is made of rubber, collisions and damage to the magnet are avoided during conveying. Further, when the cylindrical magnet reaches the middle of the conveying table 1, sensor detection and numerical control activate the motor screw assembly 401. The motor screw assembly 401 drives the moving seat 403 to a lateral position via a motor, causing the moving seat 403 to move along with the drive motor 402. The clamping head 4 moves laterally, with the output shaft of the drive motor 402 penetrating the moving seat 403. This stabilizes the axial movement of the output shaft of the drive motor 402. Under the axial movement of the clamping head 4, both clamping heads 4 simultaneously apply axial pressure to the ends of the cylindrical magnet, achieving the positioning and clamping effect of the cylindrical magnet. Subsequently, under the lifting drive of the hydraulic component 301, the clamping head 4 and its auxiliary components are lifted, achieving the positioning and lifting effect of the cylindrical magnet. This allows the cylindrical magnet to move above the waste collection chamber 5 and the barrier brush 6. The cylindrical magnet can rotate around its central axis under the drive of the clamping head 4 and the drive motor 402, facilitating subsequent grinding of the outer surface of the cylindrical magnet.

[0022] Based on the above technical solution, the movable platform 8 is movably installed in the middle of the fixed plate 7. A grinding seat 9 is also movably mounted through the movable platform 8. A grinding component 11 is telescopically mounted on the front center of the grinding seat 9. An airbag belt 10 and a waste collection channel 12 are located on the front edge of the grinding seat 9. The airbag belt 10 and the waste collection channel 12 are used to push and discharge waste material from the cylindrical magnet. The movable platform 8 moves laterally via a hydraulic guide rail 801 fixed on the fixed plate 7. The movable platform 8 and the grinding seat 9 form a relatively telescopic structure. The grinding seat 9 is driven to telescopically move by a motor drive assembly 901 on the movable platform 8. The grinding component 11, the airbag belt 10, and the grinding seat 9 are all designed with an arc-shaped structure. The grinding component 11 is driven to telescopically extend and be positioned by an electromagnetic component inside the middle of the grinding seat 9. A pump is externally connected to the back of the grinding seat 9 via a pipe. In this scheme, since the cylindrical magnet has moved to the horizontal plane where the grinding base 9 is located, the use of the motor-driven assembly 901, under the action of motor drive and lead screw movable connection, allows the motor-driven assembly 901 to be installed as... Figure 8On the movable table 8 shown, the grinding seat 9 and the movable table 8 move relative to each other, allowing the grinding seat 9 to quickly and effectively approach the cylindrical magnet to be ground. Furthermore, a grinding component 11 is movably mounted in the middle of the grinding seat 9. The grinding component 11 is bolted to its mounting shaft. Under the action of changing the size of the electromagnetic component magnet, the mounting position of the grinding component 11 can be changed by the extension and retraction of the shaft, so that when the grinding component 11 extends to its maximum extent, it can contact the rotating cylindrical magnet to be ground, thus achieving its grinding process. At the same time, the movable table 8 and the grinding seat 9 can be further moved laterally under the drive of the hydraulic guide rail 801, and their movement trajectory is parallel to the cylindrical magnet to be ground, achieving full processing of the outer surface of the cylindrical magnet.

[0023] In the above-mentioned cylindrical magnet outer surface grinding process, the back of the grinding seat 9 is connected to an external pump through a pipe, which can use negative pressure adsorption to remove waste material during the grinding process.

[0024] Furthermore, this solution also includes a waste removal structure during the grinding process of the cylindrical magnet. Specifically, the grinding seat 9 is fitted to the outer side of the cylindrical magnet for grinding the outer cylindrical surface while the magnet rotates; simultaneously, the outer side of the airbag belt 10 is provided with a wear-resistant layer for damping the pushing of waste material on the outer side of the cylindrical magnet; the exhaust pipe 1201 is rotatably installed on the left and right sides of the grinding seat 9, wherein a waste collection airbag 1202 is fixed to the outer side of the exhaust pipe 1201, and the exhaust pipe 1201, the waste collection airbag 1202, the waste collection channel 12, and the airbag are connected. The belts 10 are configured in a one-to-one correspondence. The waste collection bag 1202, during rotation, achieves a kneading and removal of waste material from the outer side of the cylindrical magnet through the air bag belt 10. The exhaust pipe 1201 is driven to rotate by airflow. The exhaust pipe 1201 also has an exhaust port in the middle. The exhaust port and the waste collection channel 12 work together to remove the waste material generated during the grinding of the cylindrical magnet. The upper end of the exhaust pipe 1201 is also rotatably installed with a guide pipe 1203 through a sealed bearing. The upper end of the exhaust pipe 1201 also has a turbine blade fixed inside, which is driven to rotate by airflow. In the above scheme, during the grinding process of the outer surface of the cylindrical magnet, the residual fine waste will be attracted to the magnet surface due to its stickiness and magnetism during the rework of the magnet. Such residual impurities are still easy to remain on the outer surface of the magnet under the impact of airflow or liquid. Therefore, by setting up the airbag belt 10, after the grinding part 11 has completed the grinding process of the cylindrical magnet, the grinding part 11 is recycled and attached to the grinding seat 9. At this time, the airbag belt 10 is exposed and directly contacts the outer surface of the cylindrical magnet. The airbag belt 10 can move laterally with the grinding seat 9, and can push and concentrate the residue on the outer surface of the magnet under the action of compression and damping, which is convenient for collection and treatment.

[0025] Simultaneously, driven by the airflow of the exhaust pipe 1201, it can rotate and move the waste collection bag 1202 on it. During the rotation, the waste collection bag 1202 and the bag belt 10 squeeze each other and generate damping, pushing the bag belt 10 to push the concentrated magnet outer surface adsorbed residual kneading to the location of the waste collection channel 12. The negative pressure at the location of the waste collection channel 12 carries away the magnet waste, improving the waste discharge effect. At the same time, the rotation of the exhaust pipe 1201 is driven by the airflow, and its airflow waste discharge can also further push the adhered waste to the waste collection channel 12, improving the waste discharge effect.

[0026] Example 2: Based on Example 1, this invention further discloses a waste collection chamber 5, symmetrically installed above the clamping head 4 on the conveyor table 1. The waste collection chamber 5 has a barrier brush 6 at its waste inlet, and a fixing plate 7 is provided on the outside of the waste collection chamber 5. The waste collection chamber 5 is installed symmetrically, with a pump connected to it via a pipe. The barrier brushes 6 are intersected between adjacent waste collection chambers 5, preventing waste from falling and cleaning the waste on the outside of the cylindrical magnet. The use of the waste collection chamber 5 and the barrier brushes 6 allows for further cleaning of the outer surface of the cylindrical magnet as it passes through the areas where both the waste collection chamber 5 and the barrier brushes 6 are located.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
