Description

Technical Field

[0001] This utility model relates to the technical field of polishing devices, specifically a surface polishing device for powder metallurgy products. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, followed by forming and sintering, to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy shares similarities with ceramic production, both belonging to powder sintering technology.

[0003] Existing powder metallurgy polishing and grinding equipment has the problem of generating a large amount of powder during the grinding process, which brings inconvenience to actual operation; and the existing powder metallurgy polishing and grinding equipment also has the problem of not being able to collect the powder easily after grinding.

[0004] Upon investigation, a Chinese utility model patent (publication number: CN216542751U) discloses a polishing and grinding device for powder metallurgy products, including a base. A mounting plate is fixedly installed at the top center of the base. A storage box is movably screwed to the top of the mounting plate by two sets of fixing bolts. A first support rod is fixedly installed at one side of the top of the mounting plate.

[0005] Although the aforementioned patent can prevent dust from spreading outward to a certain extent by setting up two sets of baffles and avoid environmental pollution caused by dust diffusion, the dust is relatively light and some of it will float in the air. When workers polish metallurgical products, they will inhale the dust, which seriously endangers their health.

[0006] Therefore, this utility model provides a surface polishing device for powder metallurgy products to solve the above problems. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] This utility model provides a surface polishing device for powder metallurgy products, such as... Figures 1-5As shown, the technical solution includes a frame 1, a grinding device 2 mounted on the frame 1, and a clamping device 3. It should be noted that the grinding device 2 includes a drive motor and a hydraulic telescopic rod for driving the grinding disc to rotate and rise. The clamping device 3 includes two hydraulic telescopic rods for pushing the clamping blocks to move. The drive motor, hydraulic telescopic rods, grinding disc, and clamping blocks are all existing technologies and will not be elaborated upon here. A placement plate 4 is fixedly connected to the frame 1, and collection boxes 5 are symmetrically fixed to the frame 1. A first mesh plate 6 is fixedly connected to the side wall of the collection box 5, and a second mesh plate 7 is fixedly connected to the frame 1. A mounting frame 10 is fixedly connected inside the frame 1, and a fan 11 is fixedly connected to the bottom of the mounting frame 10. A collection device is located above the fan 11. The dust collection bag 12 is slidably connected to the frame 1, and the mounting plate 8 for installing the dust collection bag 12 is set up. By setting up the dust collection bag 12, the dust floating in the air is collected. With the help of the fan 11, the airflow causes the dust in the air to enter the first screen plate 6 and the second screen plate 7 with the air, and then enter the dust collection bag 12 for collection, preventing the floating dust from being inhaled by the staff and causing harm to their bodies. There are multiple limiting mechanisms between the mounting plate 8 and the frame 1. The limiting mechanism includes a locking block 15 and a spring 18. The mounting plate 8 can be fixed on the frame 1 by the setting limiting mechanism. The mounting plate 8 can be pulled off the frame 1 by releasing the limiting block 15, so that the staff can remove the mounting plate 8 to replace the dust collection bag 12.

[0030] A guide plate 9 is fixedly connected inside the collection box 5. The bottom of the collection box 5 has an opening, and the second mesh plate 7 is set at the opening of the collection box 5. When in use, the fan 11 is turned on to drive air circulation. Part of the circulating air carries the dust from the second mesh plate 7 into the dust collection bag 12, and the other part of the air carries the dust from the first mesh plate 6 into the collection box 5. Under the action of the guide plate 9, the dust in the collection box 5 enters the dust collection bag 12 from the bottom opening for collection, so as to prevent the floating dust from being inhaled by the staff.

[0031] Multiple screws 13 are fixedly connected to the mounting plate 8. The top of the screws 13 is tapered and penetrates the side wall of the dust collection bag 12. A positioning block 14 is threaded onto the screw 13. Multiple mounting slots are provided in the mounting plate 8, and a locking block 15 is slidably connected in the mounting slot. A connecting plate 16 is fixedly connected in the mounting slot. The two ends of the spring 18 are fixedly connected to the locking block 15 and the connecting plate 16, respectively. The limiting mechanism also includes a round rod 17, which is rotatably connected to the locking block 15. The end of the round rod 17 away from the locking block 15 slides through the connecting plate 16. The spring 18 is sleeved on the round rod 17. The limiting mechanism also includes a lever 19, which is fixedly connected to the round rod 17. A positioning slot 20 is provided on the side wall of the mounting slot, and the lever 19 is movably connected in the positioning slot 20. Multiple slots are provided on the side wall of the frame 1, and the locking block 15 is engaged in the slot.

[0032] When in use, pulling the lever 19 moves the round rod 17. The round rod 17 moves the locking block 15 out of the slot and compresses the spring 18. At this time, rotating the lever 19 limits the lever 19 in the positioning groove 20 to prevent the compressed spring 18 from returning to its original position. At this time, the mounting plate 8 can be pulled out from the frame 1. Then, rotating the positioning block 14 removes it from the screw 13, and the dust collection bag 12 can be removed for easy dust handling or replacement.

[0033] After the mounting plate 8 is removed, rotate the lever 19 to release the positioning groove 20 from the lever 19. At this time, the compressed spring 18 resets and pushes the locking block 15 out of the mounting groove. When the mounting plate 8 is fixed again, the mounting plate 8 can be directly pushed into the frame 1. During this process, the frame 1 will squeeze the inclined surface of the locking block 15, so that the locking block 15 is engaged in the slot, thereby limiting and fixing the mounting plate 8.

[0034] In summary: During operation, the fan 11 is started to circulate air. Part of the circulating air carries dust from the second mesh plate 7 into the dust collection bag 12, while the other part of the air carries dust from the first mesh plate 6 into the collection box 5. Under the action of the guide plate 9, the dust in the collection box 5 enters the dust collection bag 12 from the bottom opening for collection.

[0035] When handling dust or replacing the dust collection bag 12, pull the lever 19 to move the round rod 17. The round rod 17 moves the locking block 15 out of the slot and compresses the spring 18. At this time, rotate the lever 19 to limit the lever 19 in the positioning groove 20 to prevent the compressed spring 18 from returning to its original position. At this time, the mounting plate 8 can be pulled out from the frame 1. Then, rotate the positioning block 14 to remove it from the screw 13. The dust collection bag 12 can be removed for easy handling of dust or replacement of the dust collection bag 12.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
