Description

Technical Field

[0001] This invention relates to magnetic field-assisted polishing technology, specifically to a belt-type magnetic shearing thickening polishing medium circulation device and method. Background Technology

[0002] In the magnetic shear thickening polishing process, the media circulation device plays a crucial role. This device effectively manages the flow of the polishing media during polishing, ensuring that the polishing media remains in the appropriate position and continuously participates in the processing. By controlling the uniform distribution and movement of the polishing media through the circulation device, the uniformity of the polishing media during polishing can be improved, while also increasing resource utilization, reducing production costs, minimizing surface defects, and improving surface smoothness and precision, thereby enhancing the surface quality of the final product.

[0003] The circulation device for magnetorheological polishing slurry is a crucial component of a magnetorheological polishing system. Commercially available magnetorheological polishing devices primarily employ centrifugal pumps or peristaltic pumps for transporting the magnetorheological slurry. The Chinese Patent Document Database publishes invention patent CN102632435A, which discloses a dual-flexible grinding head magnetorheological polishing device. This device uses a centrifugal pump as the transfer pump for a high-flow-rate circulation system and a peristaltic pump as the recovery pump. Chinese patents CN107009274A (titled "A Gravity-Driven Circulation Device for Magnetorheological Polishing Slurry") and CN105904311B (titled "A Polishing Composite Machine Tool and Polishing Method") both utilize water pumps for transporting the magnetorheological slurry. Because magnetic shear-thickening polishing media contain more iron powder and shear-thickening components compared to traditional magnetorheological fluids, they exhibit higher viscosity and shear-thickening properties not found in traditional magnetorheological fluids under the application of an external magnetic field. After prolonged processing, they transform into a solid or semi-solid state. This characteristic makes it difficult to recover and recycle magnetic shear-thickening polishing media using traditional magnetorheological polishing media circulation methods. Therefore, developing a media circulation device and method specifically for magnetic shear-thickening polishing media is of paramount importance. Summary of the Invention

[0004] To address the problem of the polishing medium's inability to maintain stable circulation and reliable operation for extended periods during magnetic shear thickening polishing, and to improve the utilization efficiency of the polishing medium during the polishing process, this invention provides a belt-type magnetic shear thickening polishing medium circulation device and method. This device enables stable delivery and recycling of the magnetic shear thickening polishing medium, and improves the circulation capacity of the magnetic shear thickening polishing medium.

[0005] The technical solution provided by the belt-type magnetic shearing thickening polishing media circulation device of the present invention is as follows: The device includes a media conveying module 1, a polishing wheel bracket 2, a mounting plate 3, a polishing wheel timing belt 4, a polishing wheel drive motor 5, a stirrer motor 6, a media storage tank 7, a media receiving device 8, a pulley bracket 9, a media guide plate 10, and a tensioning wheel bracket 11. The media conveying module includes a conveyor belt 12, a polishing wheel 13, a pulley 14, and a tensioning wheel 15. The polishing wheel 13 includes a magnetic yoke 16, cylindrical magnetic poles 17, and a polishing wheel shell 18. The polishing wheel bracket 2 is mounted on the mounting plate 3. The polishing wheel drive motor 5 is mounted on the top of the mounting plate 3. The polishing wheel timing belt 4 is installed between the polishing wheel drive motor 5 and the polishing wheel 13. The stirrer motor 6 is mounted on the mounting plate 3. The media storage tank 7... The medium receiving device 8 is installed on the side of the medium storage tank 7, with the side scraper in contact with the surface of the conveyor belt 12 and the top connected to the medium input end of the surface of the mounting plate 3. The pulley bracket 9 is installed on the mounting plate 3, the pulley 14 is installed on the pulley bracket 9, the tension wheel bracket 11 is installed on the mounting plate 3, the tension wheel 15 is installed on the tension wheel bracket 11, the polishing wheel 13 is installed on the polishing wheel bracket 2 and is driven by the polishing wheel drive motor 5 and the polishing wheel synchronous belt 4.

[0006] The beneficial effects of this invention are as follows: 1.

Utilizing the sensitive response of the magnetic shear thickening polishing medium to a magnetic field, it realizes the transformation and transportation of the magnetic shear thickening medium from liquid to solid state, overcoming problems such as pipeline blockage caused by pumps and pipelines transporting shear thickening fluids, and improving the smoothness of the magnetic shear thickening polishing medium circulation. 2. The belt-type magnetic shear thickening polishing medium circulation device of this invention, through the arrangement of opposing magnetic fields of the same level, forces more magnetic lines of force to be conducted along the magnetic yoke, increasing the magnetic field strength between the polishing wheel and the magnetic yoke. This allows the magnetic shear thickening polishing medium to more easily overcome the influence of gravity and circulate during transportation, improving the efficiency and stability of the medium circulation.

Detailed Implementation

[0011] Specific implementation method one: Combining Figure 1 , Figure 2 and Figure 3The device described in this embodiment includes a media conveying module 1, a polishing wheel bracket 2, a mounting plate 3, a polishing wheel timing belt 4, a polishing wheel drive motor 5, a stirrer motor 6, a media storage tank 7, a media receiving device 8, a pulley bracket 9, a media guide plate 10, and a tensioning wheel bracket 11. The media conveying module includes a conveyor belt 12, a polishing wheel 13, a pulley 14, and a tensioning wheel 15. The polishing wheel 13 includes a magnetic yoke 16, cylindrical magnetic poles 17, and a polishing wheel housing 18. The polishing wheel bracket 2 is mounted on the mounting plate 3. The polishing wheel drive motor 5 is mounted on the top of the mounting plate 3. The polishing wheel timing belt 4 is installed between the polishing wheel drive motor 5 and the polishing wheel 13. The stirrer motor 6 is mounted on the mounting plate 3. The media storage tank 7 is mounted on the bottom of the mounting plate 3, and its top is connected to the... The stirrer motor 6 is connected. The medium receiving device 8 is installed on the side of the medium storage tank 7. The side scraper is in contact with the surface of the conveyor belt 12. The top is connected to the medium input end of the mounting plate 3. The pulley bracket 9 is installed on the mounting plate 3. The pulley 14 is installed on the pulley bracket 9. The tension wheel bracket 11 is installed on the mounting plate 3. The tension wheel 15 is installed on the tension wheel bracket 11. The polishing wheel 13 is installed on the polishing wheel bracket 2 and is driven by the polishing wheel drive motor 5 and the polishing wheel synchronous belt 4. The pulley 14 is driven by the polishing wheel 13 and the conveyor belt 12. The position of the tension wheel 15 is adjusted between the pulley 14 and the polishing wheel 13. The medium guide plate 10 is installed at the bottom of the medium storage tank 7. The distance between the end and the conveyor belt 12 is 2 mm. The cylindrical magnetic poles 17 are fixed on the magnetic yoke 16 in a parallel arrangement. The polishing wheel shell 18 is installed on the outside of the magnetic yoke 16. The surface is roughened to facilitate the operation of the conveyor belt 12.

[0012] Specific Implementation Method Two: Combining Figure 1 and Figure 2In this embodiment, the conveyor belt 12 is mounted on the polishing wheel 13 and pulley 14. The tensioning wheel 15 is used to adjust the tension of the conveyor belt 12 to maintain the stable, safe, and reliable operation of the transmission system. The medium receiving device 8 is mounted on the side of the medium storage tank 7 and is in contact with the surface of the conveyor belt 12. The medium flows out of the medium storage tank 7 under the guidance of the medium guide plate 10 and flows along the medium guide plate 10. When the medium approaches the polishing wheel 13, it adheres to the surface of the conveyor belt 12 under the attraction of the strong magnetic field. Under the action of the strong magnetic field, the medium changes from a liquid state to a solid state. The polishing wheel 13 rotates under the drive of the polishing wheel drive motor 5, which in turn drives the conveyor belt. 12 is running. The medium participates in the polishing operation at the lowest point of the conveyor belt 12. When the conveyor belt 12 runs out of the polishing area, under the action of the strong magnetic field on the surface of the polishing wheel 13, the solid medium adsorbed on the surface of the conveyor belt 12 overcomes gravity and is transported upward. After being transported to the highest point of the conveyor belt 12, the medium changes from a solid state to a solid-liquid coexistence state due to the removal of the magnetic field control. At this time, the conveyor belt is in a horizontal running state and the medium will not leave the conveyor belt 12. When the conveyor belt 12 runs to the pulley 14, under the action of the medium receiving device 8, the medium separates from the conveyor belt 12 and enters the medium storage tank 7 for uniform stirring. In the medium storage tank 7, the medium changes from a solid-liquid coexistence state back to a liquid state under the stirring action.

[0013] Specific implementation method three: Combining Figure 3 The cylindrical magnetic poles 17 described in this embodiment are installed on both sides of the magnetic yoke 16, arranged with the same poles facing each other. Since the magnetic yoke is made of magnetically conductive material, the magnetic field of the same poles on both sides of the magnetic yoke propagates in the magnetic yoke. The magnetic lines of force are drawn out from the tip of the magnetic yoke and leak magnetic field through the air gap between the two magnetic yokes. Due to the leakage magnetic field, a strong magnetic field region is formed in the air gap. That is, a strong magnetic field region along the polishing wheel is formed on the surface of the polishing wheel. In the strong magnetic field region, the polishing medium changes from liquid to solid on the surface of the conveyor belt and is transported and moved with the movement of the conveyor belt.

[0014] Specific implementation method four: Combination Figure 1 , Figure 2 ,and Figure 3 Note that the media circulation steps in this embodiment, using any one of specific embodiments one, two, or three, are as follows:

[0015] (1) Start the polishing wheel drive motor 5 and drive the media conveying module to work;

[0016] (2) Adjust the position of the tension wheel 15 to ensure that the conveyor belt 12 runs smoothly;

[0017] (3) Adjust the position of the medium receiving device 8 to ensure that the side scraper at the end can be in close contact with the conveyor belt 12;

[0018] (4) Pour the liquid magnetic shear thickening polishing medium into the medium storage tank 7;

[0019] (5) Start the stirrer motor 6 to make the medium storage tank 7 work. After the polishing medium is fully mixed in the medium storage tank 7, it flows into the medium guide plate 10 under the action of gravity.

[0020] (6) The medium flows into the polishing area under the guidance of the medium guide plate 10, and then is attracted to the surface of the conveyor belt 12 by the magnetic field generated by the polishing wheel 13 and enters the polishing area. The polishing medium is transformed into a solid state under the influence of the magnetic field in the polishing area and is attracted to the surface of the conveyor belt 12.

[0021] (7) After the conveyor belt 12 carries the solid polishing medium away from the polishing area, it continues to run at the medium receiving device 8. The scraper of the medium receiving device 8 scrapes the polishing medium off the surface of the conveyor belt 12 and the polishing medium enters the medium storage tank 7.

[0022] (8) The polishing medium is stirred again in the medium storage tank 7 and turned into a liquid state, thus completing one cycle of the polishing medium.

[0023] (9) Repeat (6), (7), and (8) to achieve the recycling of the magnetic shear thickening polishing medium.
