[0002] Metal surface spraying is an important surface treatment technology, aiming to protect metals from oxidation and corrosion, improve the aesthetics and functionality of the metal surface, and facilitate the anti-rust protection of metal parts. It has been widely used in the field of metal processing.

[0003] After retrieval, the patent with the Chinese patent number CN221268642U discloses a spraying device for automotive metal parts. The parts are placed on a turntable, and a cylinder pushes a pressing head down to tightly press the top of the parts. The turntable drives the parts to rotate stably. The spraying pump pumps the paint in the material tank to the nozzle to spray the parts. The second motor drives the first lead screw to rotate, thereby driving the nozzle to move up and down to improve the spraying effect. After spraying is completed, the third motor drives the second lead screw to rotate, thereby driving the scraper to move to clean the top of the turntable.

[0028] Clamping mechanism, the clamping mechanism is installed in the inner cavity of the workbench 1 and is used for clamping metal parts;

[0029] Working mechanism, the working mechanism is installed on the top of the workbench 1 and is used for spraying and drying metal parts. The working mechanism includes a spraying component, a lifting component and a drying component. The lifting component is located on the top of the workbench 1 and is used for adjusting the height of the spraying component. The spraying component is installed at the bottom of the lifting component and is used for spraying metal parts. The drying component is installed on the top of the workbench 1 and is used for drying metal parts.

[0030] The lifting component includes a support frame 3 installed on the top of the workbench 1. A hydraulic cylinder 4 is installed on the top of the support frame 3. A hydraulic telescopic rod 5 is installed at the bottom of the hydraulic cylinder 4. A lifting frame 6 is installed at the bottom of the output rod of the hydraulic telescopic rod 5. A limiting rod 7 is installed between the top of the inner cavity of the lifting frame 6 and the support frame 3.

[0031] The spraying component includes a first motor 8 installed in the inner cavity of the lifting frame 6. A lead screw 9 is fixedly connected to the front of the output shaft of the first motor 8. A moving block 10 is threadedly connected to the outer circle of the lead screw 9. A spray head 11 is installed at the bottom of the moving block 10.

[0032] The drying component includes a support seat installed on the top of the workbench 1. A dryer 12 is installed at the top of the inner cavity of the support seat. A liquid storage tank 13 is also installed on the top of the support seat. A pump body is installed in the inner cavity of the liquid storage tank 13 and is connected to the spray head 11 through a connecting pipe.

[0033] In the embodiment of the present utility model, after spraying is completed, the dryer 12 is started to generate hot air to dry the surface of the metal parts. The dryer 12 can ensure that the heat can evenly cover the entire spraying area, accelerate the curing of the paint, and avoid flowing or sticking.

[0034] Please refer to Figures 1-4 , the clamping mechanism includes a moving frame 14 slidably connected in the inner cavity of the groove 2. An electric push rod 15 is fixedly connected to the inner wall of the moving frame 14. A first rack 16 is installed on one side of the electric push rod 15. A pin shaft 17 is installed in the inner cavity of the moving frame 14. A first gear 18 is installed on the outer circle of the pin shaft 17. The first rack 16 and the first gear 18 are meshed with each other. A clamping plate 19 is installed on one side of the first gear 18. The first gear 18, the first rack 16 and the clamping plate 19 are distributed in a multi-group matrix array. A moving component for moving the clamping mechanism is installed at the bottom of the clamping mechanism.

[0035] The moving component includes a second motor 20 in the inner cavity of the installation groove 2. A second rotating shaft 21 is installed between the second motor 20 and the inner wall of the groove 2. The output shaft of the second motor 20 is fixedly connected to the second rotating shaft 21 through a coupling. A second gear 22 is installed on the outer ring of the second rotating shaft 21. A second rack 23 is installed at the bottom of the moving frame 14. The second gear 22 meshes with the second rack 23. A sealing plate 24 is hinged to the front of the moving frame 14.

[0036] In the embodiment of the present invention, when the metal part is placed in the moving frame 14, the electric push rod 15 is started. The electric push rod 15 pushes the first rack 16 to move forward. The first rack 16 meshes with the first gear 18, driving the first gear 18 to rotate. Since the first gear 18 is connected to the clamping plate 19, the rotation of the gear will drive the clamping plate 19 to move closer to the center, realizing the clamping and fixing of the metal part. During this process, multiple groups of the first gear 18, the first rack 16 and the clamping plate 19 act synchronously to ensure uniform and stable clamping.

[0037] During use, the moving frame 14 is in the initial position of the groove 2, and the clamping plate 19 is in an open state, ready to receive the metal part to be sprayed. When the metal part is placed in the moving frame 14, the electric push rod 15 is started. The electric push rod 15 pushes the first rack 16 to move forward. The first rack 16 meshes with the first gear 18, driving the first gear 18 to rotate. Since the first gear 18 is connected to the clamping plate 19, the rotation of the gear will drive the clamping plate 19 to move closer to the center, realizing the clamping and fixing of the metal part. During this process, multiple groups of the first gear 18, the first rack 16 and the clamping plate 19 act synchronously to ensure uniform and stable clamping.

[0038] In order to adapt to metal parts of different sizes or adjust the spraying position, the second motor 20 drives the second rotating shaft 21 and the second gear 22 to rotate. The second gear 22 meshes with the second rack 23 at the bottom of the moving frame 14, driving the moving frame 14 and the clamped metal part to move along a predetermined track in the groove 2 to the spraying position.

[0039] After the first motor 8 is started, it drives the lead screw 9 to rotate. The threaded connection between the lead screw 9 and the moving block 10 enables the moving block 10 to move axially along the lead screw 9, thereby driving the spray head 11 to be accurately positioned in the horizontal direction. The spray head 11 receives the paint from the liquid storage tank 13 and pressurized by the pump body through the connecting pipe, and sprays the metal part evenly. The hydraulic cylinder 4 drives the hydraulic telescopic rod 5 to extend or shorten, thereby driving the lifting frame 6 and the spraying component installed thereon to lift and lower, completing the spraying process. The limiting rod 7 ensures the stability during the lifting process and prevents the lifting frame 6 from shifting or shaking.

[0040] After spraying is completed, the second motor 20 is started again. In the same working principle as above, the rotation of the second motor 20 will drive the moving frame 14 to move until the moving frame 14 and the sprayed metal part move to the bottom of the drying assembly. The dryer 12 is started to generate hot air to dry the surface of the metal part. The dryer 12 can ensure that the heat can evenly cover the entire spraying area, accelerate the curing of the paint, and avoid flowing or sticking. After drying is completed, the clamping mechanism is loosened and the metal part is removed from the equipment.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit. The scope of the present invention is defined by the appended claims and their equivalents.
