[0002] With the continuous advancement and development of industrial manufacturing technology, the requirements for workpiece surface quality are becoming increasingly stringent, especially in precision machining industries such as semiconductors, optical glass, and automotive parts manufacturing. To meet the high precision requirements of these industries, the performance of precision grinding and polishing equipment is paramount. With increasing automation, modern industrial production increasingly utilizes automated precision grinding and polishing machines to complete processing tasks. This type of equipment not only improves production efficiency but also ensures the processing accuracy and surface quality of the products.

[0003] While existing pendant grinding and polishing machines can achieve high processing precision, in practical applications, the lack of an effective circulation and filtration mechanism for the polishing slurry means that impurities in the slurry cannot be removed in time. This reduces the effective utilization cycle of the polishing slurry, increases production costs, and if the particulate matter in the polishing slurry cannot be effectively separated, it may re-adhere to the workpiece surface, causing secondary pollution and affecting the quality of the final product.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a pendulum fine polishing machine with a polishing liquid circulation and filtration mechanism, including a polishing machine base 1, a polishing liquid spraying mechanism 2 on the top of the polishing machine base 1, a liquid outlet 4 at the bottom of the polishing chamber inside the polishing machine base 1, a filter box 5 installed at the bottom of the polishing machine base 1 outside the liquid outlet 4, a rotating disk 6 driven by a motor at the bottom of the filter box 5, a filter cylinder 7 installed on the rotating disk 6, a plurality of filter screens 8 installed around the side wall of the filter cylinder 7 through a passage, filter elements 9 installed on both sides inside the filter box 5, and a circulation pump 3 installed on one side outside the filter box 5. The suction end extends into the filter housing 5, and the outlet end of the circulating pump 3 can be connected to the spray pipe of the polishing spray mechanism 2 via a connecting pipe. In this structure, the polishing base 1 can deliver polishing liquid to the polishing chamber via the spray pipe of the polishing spray mechanism 2. After spraying the workpiece, the polishing liquid flows into the filter housing 5 through the outlet 4. Inside the filter housing 5, a rotating disk 6 driven by a motor rotates the filter cylinder 7 at the bottom. Several filter screens 8 installed around the openings on the side wall of the filter cylinder 7 perform initial filtration of impurities in the polishing liquid. Simultaneously, filter elements 9 installed on both sides inside the filter housing 5 further adsorb and filter residual fine particles. During this process, the circulating pump 3 extends through its... The filtered clean polishing liquid is drawn from the suction end inside the filter housing 5 and then transported back to the polishing spray mechanism 2 through a connecting pipe, realizing the recycling of the polishing liquid. This effectively removes impurities from the polishing liquid, extends its service life, reduces replacement frequency, lowers production costs, ensures the quality of the polishing liquid, avoids secondary pollution, and improves the machining accuracy and surface finish of the workpiece. The upper ends of the inner walls on both sides of the filter housing 5 are equipped with elastic snap-fit ​​pieces 10, each with a snap-fit ​​interface that matches the structure of the filter element 9. When installing or replacing the filter element 9, the operator only needs to align the filter element 9 with the elastic snap-fit ​​piece. When the snap-fit ​​interface on the filter element 10 is gently pressed, the elastic snap-fit ​​10 will deform appropriately under external force. After the filter element 9 is fully embedded, the elastic snap-fit ​​10 will automatically return to its original shape, thus firmly fixing the filter element 9 in the filter housing 5. This ensures that the filter element 9 will not shift or leak due to vibration or water flow impact during the filtration of polishing liquid, guaranteeing the filtration effect while simplifying the installation and disassembly process of the filter element 9, improving maintenance efficiency and reducing downtime, thereby enhancing the working stability and reliability of the entire polishing machine. A column 11 is fixed at the center of the top of the rotating disk 6, and the top of the column 11 is equipped with an arched guide plate 12. The top surface of the guide plate 12 is evenly surrounded by several guide grooves, and the inner wall of the guide grooves at the top of the guide plate 12 has an arc-shaped structure. When the polishing liquid flows into the filter box 5, it is guided onto the guide plate 12. The several guide grooves evenly surrounded on the top surface of the guide plate 12, combined with the arc-shaped inner wall structure, allow the polishing liquid to be distributed smoothly and evenly along the guide grooves.This design increases the contact time and opportunity between the polishing fluid and the filter cartridge 7 and filter element 9, thereby improving filtration efficiency and ensuring that impurities in the polishing fluid are fully trapped and filtered. Simultaneously, the arc-shaped guide groove design of the guide plate 12 reduces the resistance of the polishing fluid during flow, preventing turbulence or dead zones and ensuring smooth operation of the polishing fluid circulation system. This, in turn, improves the overall performance and polishing quality of the polishing machine. Both the upper and lower ends of the filter screen 8 are welded and fixed with inserts 13, and both the upper and lower ends of the filter cartridge 7's opening have grooves that match the structure of the inserts 13. The inserts 13 are connected to locking screws via a threaded structure. When installing or replacing the filter screen 8, the operator aligns the insert 13 with the groove in the filter cartridge 7, inserts it, and then tightens the locking screw. The self-locking property of the threaded structure ensures that the insert 13 is firmly fixed in the groove, thus securely installing the filter screen 8 on the filter cartridge 7. This not only simplifies the installation of the filter screen 8... The installation and disassembly process ensures the stability and sealing of the filter screen 8 during operation, preventing it from loosening or falling off due to vibration or pressure changes during high-speed flow of the polishing fluid. This ensures that impurities in the polishing fluid are effectively filtered. The top of the filter housing 5 is open, and the four corners of the top of the filter housing 5 are connected to the bottom wall of the polishing machine base 1 by fixing bolts. A sealing ring is provided on the inner side of the top edge of the filter housing 5. This structure ensures the stable installation of the filter housing 5 by connecting it to the bottom wall of the polishing machine base 1 via the four corner fixing bolts. Simultaneously, the sealing ring on the inner side of the top edge of the filter housing 5 acts as a seal when the filter housing 5 is connected to the polishing machine base 1, preventing the polishing fluid from leaking from the connection point during circulation. This not only ensures the airtightness and stability of the polishing fluid circulation mechanism but also facilitates the operator's inspection and maintenance of the internal components through the open structure of the filter housing 5.

[0018] Working Principle: When using this pendulum fine grinding and polishing machine with a polishing liquid circulation and filtration mechanism, the polishing machine base 1 first delivers polishing liquid to the polishing chamber through the spray pipe of the polishing spray mechanism 2. After the polishing liquid finishes spraying the workpiece, it flows into the filter box 5 from the outlet 4. At this time, the polishing liquid is first guided to the guide plate 12. Several guide grooves on the top surface of the guide plate 12 allow the polishing liquid to be distributed smoothly and evenly. Then, the bottom of the filter box 5 is driven by a motor-driven rotating disk 6, which rotates the filter cylinder 7. Several filter screens 8 installed around the openings on the side wall of the filter cylinder 7 perform initial filtration of impurities in the polishing liquid. The two filter elements 9 further adsorb and filter residual fine particles. During this process, the circulation pump 3 draws the filtered clean polishing liquid through its suction end that extends into the filter box 5, and then transports it back to the polishing spray mechanism 2 through the connecting pipe to realize the recycling of polishing liquid. When it is necessary to clean and maintain the filter elements 9 and filter screen 8 inside the filter box 5, the filter element 9 can be detached from the elastic snap fastener 10, and the filter screen 8 can be detached from the through slot of the filter cylinder 7 by removing the fixing screws on the insert 13, thereby quickly disassembling and maintaining the filter element 9 and completing a series of tasks.

[0019] 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.
