[0032] Please see Figure 1-3 This utility model provides a technical solution: an automatic dust-collecting workbench for metal polishing, comprising:

[0033] The main body of the workbench 1 has a work surface 2 on its top and a cabinet 3 along the three edges of the work surface 2.

[0034] The first mesh plate 4 is arranged on the inner side wall of the cabinet 3, and several guide vanes 5 are provided on it;

[0035] The second mesh plate 6 is arranged on the top of the dust collection trough 7 opened on the top of the workbench surface 2. Several mesh holes 8 are arranged in a matrix on it. A filter screen is set at the outlet of the dust collection trough 7 and connected to the air inlet of the negative pressure fan in the main body of the workbench 1. The air outlet of the negative pressure fan is connected to the first mesh plate 4.

[0036] The dust baffle 9 is raised and lowered on one side of the opening of the cabinet 3 via a guide mechanism. The guide mechanism includes a guide plate 10 with a rack 13 on its surface, a gear 12 meshing with the rack 13, and a clamp 14 on the dust baffle 9 for positioning the gear 12. The guide plate 10 is positioned on the side of the workbench body 1 and the cabinet 3. The gear 12 is rotatably connected to a rotating shaft 11 on the inner side of the dust baffle 9.

[0037] The dust baffle 9 is a U-shaped plate that fits snugly against the surfaces of the workbench body 1 and the cabinet 3. Vertically extending guide grooves on the inner side of the dust baffle 9 are vertically slidably connected to the raised ribs on the surfaces of the workbench body 1 and the cabinet 3. This improves the flexibility and stability of the dust baffle 9 as it rises and falls at the opening of the cabinet 3.

[0038] At least two sets of gears 12 and racks 13 are respectively arranged on both sides of the guide plate 10 to improve the stability of the dust baffle 9 in lifting and guiding.

[0039] The locking block 16 on the inner side of the locking member 14 is laterally inserted into the insertion hole 15 on the side of the dust baffle 9. Several locking blocks 16 are arranged circumferentially along the edge of the gear 12. They are laterally inserted into and locked onto the tooth groove of the gear 12 to improve the positioning strength of the gear 12 and prevent it from loosening or becoming unstable, which would cause inconvenience to the operator during grinding and insufficient blocking of flying grinding debris.

[0040] A lighting lamp 17 is mounted on the inner side of the cabinet 3 via a connecting seat 18. The lighting lamp 17 is rotatably connected to the clamping plate 20 of the connecting seat 18 via a connecting shaft 19 on the side of its base. Damping sleeves or damping pads are provided at the insertion point of the connecting shaft 19 and the clamping plate 20, and at the mating surface of the base and the clamping plate 20. This facilitates targeted lighting of the processing area within the workbench, improving work efficiency and quality. When adjusting the orientation of the lighting lamp 17, simply hold the base and rotate it up and down along the connecting shaft 19. Once in position, release the lighting lamp 17. The positioning of the lighting lamp 17 is achieved through the static friction resistance formed between the damping sleeve or damping pad and the adjacent structure.

[0041] The bottom of the workbench body 1 is provided with a drawer-type storage box 21, which is slidably disposed in the drawer slot of the workbench body 1. This facilitates the storage and organization of grinding tools, making them easy to use and improving work efficiency.

[0042] The working principle of the automatic dust-collecting workbench for metal polishing in this embodiment includes: This automatic dust-collecting workbench is used for polishing metal parts. During use, a negative pressure fan creates negative pressure in the dust collection tank while positive pressure is created on the inner side of the first mesh plate 4. Airflow is blown out through the gaps between the guide vanes 5, blocking and restricting the movement of polishing debris that splashes outwards. Then, the debris is sucked into the dust collection tank through the mesh 8 of the second mesh plate 6, achieving automatic dust collection. Dust and debris are trapped in the dust collection tank by the filter screen, and clean airflow flows to the negative pressure fan. Furthermore, the height of the dust baffle 9 can be adjusted based on the operator's body shape and usage habits to ensure that debris and dust splashing from the side where the operator stands, i.e., the opening side of the cabinet 3, are blocked, preventing contamination of the operator's work clothes and the workshop environment outside the workbench, ensuring cleanliness of the work without affecting the operator's normal operation. When adjusting the dust baffle 9, first pull out the locking piece 14 so that the locking block 16 disengages from the gear 12. Then, the dust baffle 9 can be pushed up or pulled down. During this process, the gear 12 rotates along the rotating shaft 11 and meshes with the rack 13 to achieve a guiding function. After reaching the required height, press the locking piece 14 against the worktable, and the locking block 16 will re-engage with the gear 12 to achieve positioning.

[0043] 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.
