[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. During the production and processing of bearings, polishing equipment is needed to polish the bearing rings. In the current bearing outer ring polishing process, the bearing is usually fixed by a fastener, and then the bearing rings are ground and polished by a polishing roller.

[0003] A bearing ring polishing device (authorization announcement number CN220516459U) is disclosed in the patent database. It includes a base with support legs on all four sides of the base's bottom. A first driving device is mounted on the base, and a three-jaw chuck is mounted on the first driving device. A fixed frame is mounted on the fixed frame, and a threaded rod is mounted on the fixed frame via bearings. A movable block is threadedly connected to the threaded rod, with one side of the movable block contacting one side of the fixed frame. A polishing component is mounted on the movable block. A second driving device is mounted on the fixed frame and connected to the threaded rod.

The dust removal mechanism includes a filter frame 10, which is movably embedded in the collection trough. A filter screen 11 is detachably installed inside the filter frame 10. One end of the filter frame 10 is connected to a fixing component outside the workbench 1. An air duct 12 is provided on one side of the workbench 1, and a motor 13 is fixedly installed inside the air duct 12. In this example, the dust removal mechanism also includes a crankshaft 14, which is fixedly connected to the output end of the motor 13. A fan blade 15 is connected to the lower end of the crankshaft 14. A push rod 17 is movably connected to the crankshaft 14 via a connector 16. A pump cylinder 18 is located on one side of the bottom of the collection tank. A piston 19 is connected to one end of the push rod 17 inside the pump cylinder 18. A water inlet is opened on one side of the top of the pump cylinder 18, and a one-way valve is installed inside the water inlet. A conduit with a one-way valve is connected to one end of the pump cylinder 18, and a nozzle is connected to one end of the conduit. The nozzle is connected to the side wall of the telescopic end of the hydraulic cylinder 4 via a bracket, and the nozzle is located above the polishing head. A dust suction hood is connected to the upper end of the air duct 12 via a connecting pipe, and the dust suction hood is located on the top of the support column 7. A filter frame 21 is movably installed above the internal motor 13. A filter screen 22 is detachably installed inside the filter frame 21. Both the filter frame 21 and the air duct 12 are connected to the fixed components. The dust removal mechanism can suck up some of the debris and dust generated during grinding and polishing, thereby drawing it into the air duct 12 and filtering and collecting it in the filter frame 21 after being filtered and intercepted by the filter screen 22. At the same time, it will drive water spray to rinse and cool the grinding area, and also play a role in dust suppression, allowing some dust and debris to be washed into the filter frame 10 and filtered and intercepted by the filter screen 11. This can achieve the collection of dust and debris, reduce the workload of workers, and prevent dust from spreading to the surrounding environment and polluting the environment or harming human health, making it more practical. In this example, the fixing component includes a slider 24. A groove is provided on one side of the filter frame 21 to slide and connect with the slider 24. The groove has a convex cross-section. One end of the slider 24 is connected to a guide rod 25. One end of the guide rod 25 is connected to a stop handle. A spring 27 and a stop rod 26 are sleeved on the outside of the guide rod 25. The spring 27 is located on the side closer to the filter frame 21. A limiting block 23 is symmetrically provided on one side of the filter frame 21. The two ends of the stop rod 26 are respectively inserted into the limiting blocks 23 on both sides. The fixing component allows for easy disassembly and fixing of the filter frame 21 and the filter screen 22, so as to handle the collected debris and dust and to clean or replace them.

[0023] In this example, a blower pipe 20 is provided on the rear wall of the housing 2, and several blower heads are provided on one side of the blower pipe 20. The blower pipe 20 is connected to the air guide pipe to blow away the small amount of debris remaining on the surface of the grid plate 6, causing it to fall and be collected in the filter frame 10. In this example, the structure of the filter frame 10 and the filter screen 11 is the same as that of the filter frame 21 and the filter screen 22, but the size is different. One end of the filter screen 22 extends outside the filter frame 21, and the filter screen 22 is fixedly connected to the filter frame 21 by bolts. The two ends of the connector 16 are hinged to the crankshaft 14 and the push rod 17, respectively. A sealing ring is provided on the outer wall of the piston 19 to facilitate the disassembly and replacement of the filter screen 11 and the filter screen 22.

[0024] The working principle of this utility model is as follows: During use, the starter motor 13 drives the crankshaft 14 and fan blades 15 to rotate, thereby coordinating with the dust extraction hood to suck up debris and dust generated during polishing. This debris and dust are then drawn into the air duct 12 and into the filter frame 21, where they are filtered and intercepted by the filter screen 22. This process collects the debris and dust, preventing it from spreading and polluting the environment or harming human health. Simultaneously, the crankshaft 14 drives the connecting piece 16 to continuously push and pull the push rod 17, causing the push rod 17... The piston 19 reciprocates within the pump cylinder 18, propelling water into the cylinder and delivering it to the nozzle. This water is then sprayed out to cool and rinse the polished area, preventing the workpiece from overheating during polishing. Simultaneously, it washes away debris and dust generated during polishing, partially suppressing dust. Some debris and dust fall into the filter frame 10, where they are further filtered by the filter screen 11. The debris and dust collected in the filter frame 10 are then trapped and collected. Within the filter frame 10, water passes through, achieving water recycling and saving water resources. Simultaneously, the air blown by the rotating fan blades 15 is blown out through the blower head on the blower pipe 20, sweeping away any remaining debris on the surface of the grid plate 6 and collecting it inside the filter frame 10, improving cleaning efficiency and ease of use. This device is also compatible with various bearing specifications for grinding and polishing. When it is necessary to disassemble the filter frame 21 or the filter frame 10, the handle can be held while pushing the stop rod 26 along the guide rod 25 to compress the spring 27. This causes the baffle 26 to move inward. Then, by pulling up the baffle handle, the guide rod 25, the baffle 26, and the slider 24 are moved upward, causing the slider 24 to slide in the groove until the baffle 26 is moved above the limit block 23. Then, the baffle handle can be pulled to move the filter frame 21 out of the air duct 12, thus disassembling the filter frame 21. This allows for the processing of collected debris and dust. At the same time, the connection method between the filter screen 22 and the filter frame 21 makes it easy to disassemble and replace the filter screen 22. This makes it convenient to use and more practical.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
