Description

Technical Field

[0001] This utility model belongs to the field of steel component processing technology, specifically a fixing device for powder coating of steel components. Background Technology

[0002] Steel components are commonly used in building construction as a structural element that can reduce the building's weight and improve its seismic performance and service life. To enhance the corrosion resistance and extend the service life of steel components, their surfaces are typically painted during the manufacturing process.

[0003] Chinese utility model patent CN222428388U discloses a steel structure spraying device, including a spraying box. A uniform spraying mechanism is installed above the spraying box, and a spraying fixing mechanism is installed on the left and right sides of the spraying box. The uniform spraying mechanism includes a paint can installed above the spraying box. This steel structure spraying device features fixed outer rings on the left and right sides of the spraying box, connected to a fixed inner ring via connecting rods. A fixing ring is held inside the fixed inner ring, and the fixing ring clamps both ends of the steel component using fixing screws, positioning the steel component at the midpoint inside the spraying ring for easy painting. Simultaneously, the fixing ring and fixing screws clamping the steel component facilitate the fixing of the ends of various steel components of different shapes and thicknesses, enabling the fixed painting of steel components of various shapes.

[0004] Although this spraying device can fix steel components of different shapes and thicknesses and complete the painting operation through the spraying ring, due to the variety of shapes of steel components, such as H-beams, the fixing device cannot be angled when using the above-mentioned spraying device for painting operations, and the spraying angle of the spraying ring is also fixed. This leads to the problem of uneven coating thickness when painting H-beams, which in turn affects the overall service life of the steel components.

[0005] Therefore, this utility model provides a fixing device for powder coating of steel components. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art and solve the problem of inconvenient angle adjustment of the fixed structure in the existing steel component spraying device mentioned in the background art, the present invention proposes a fixing device for steel component powder spraying.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The fixing device for powder coating of steel components of this utility model includes a workbench and a spray gun.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown, the present invention discloses a fixing device for powder coating of steel components, comprising a workbench 1 and a spray gun 2. A base 3 is fixedly connected to the workbench 1. Top plates 4 are symmetrically arranged on both sides of the top of the base 3. Two sets of guide rods 5 are symmetrically fixed between the top plates 4 and the base 3. Lifting seats 11 are arranged on the guide rods 5. A lifting drive assembly is provided between the base 3 and the top plates 4. The lifting drive assembly can drive the lifting seats 11 to move up and down. Mounting sleeves 23 are provided on opposite sides of the two lifting seats 11. Clamping components are provided on the mounting sleeves 23. A clamping assembly is provided between the mounting sleeves 23 and the lifting seats 11. It has an angle adjustment component; during operation, the operator can activate the lifting drive component according to the height of the steel component. The lifting drive component drives the lifting seat 11 to move up and down to facilitate the subsequent clamping of the steel component. After the height of the lifting seat 11 is adjusted, the clamping components on the two mounting sleeves 23 on both sides allow the operator to quickly clamp and fix both ends of the steel component. Then, the angle adjustment component drives the mounting sleeves 23 to rotate, so that the clamping components drive the steel component to rotate together. This ensures that during spraying, the unsprayed side of the steel component can be accurately aligned with the spray gun 2 after rotation adjustment, ensuring uniform coating thickness.

[0025] The lifting drive assembly includes a motor 6, a synchronous belt 9, and a lead screw 10. The motor 6 is fixedly mounted on the bottom of the top plate 4. A rotating shaft 7 is fixedly connected to the output end of the motor 6, and the top end of the rotating shaft 7 extends above the top plate 4. Two lead screws 10 are symmetrically rotatably connected between the top plate 4 and the base 3. The top ends of both lead screws 10 extend above the top plate 4. Synchronous pulleys 8 are fixedly connected to the top ends of the rotating shaft 7 and the lead screws 10. The synchronous pulleys 8 are driven by the synchronous belt 9. The lifting seat 11... Guide blocks 12 are symmetrically fixed on both sides. The guide blocks 12 are slidably connected to the guide rod 5. A threaded sleeve 13 is embedded in the guide block 12. The threaded sleeve 13 is threadedly connected to the lead screw 10. During operation, when it is necessary to adjust the height of the lifting seat 11, the motor 6 is started. The motor 6 drives the rotating shaft 7 to rotate, so that the synchronous pulley 8 and the synchronous belt 9 drive the lead screw 10 to rotate. In turn, the threaded sleeve 13 drives the lifting seat 11 to move on the guide rod 5, which makes it easy for the staff to make quick adjustments according to the size of the steel component.

[0026] The angle adjustment assembly includes a screw 16 and a mounting sleeve 17. The lifting seat 11 has a threaded groove 14 and a rotating groove 15. The screw 16 is threadedly connected in the threaded groove 14, and the mounting sleeve 17 is rotatably connected in the rotating groove 15. A limiting block 19 is fixedly connected to one end of the screw 16 near the mounting sleeve 17. The limiting block 19 cooperates with the mounting sleeve 17. The end of the mounting sleeve 17 away from the screw 16 extends to the outside of the rotating groove 15 and is fixedly connected to the mounting sleeve 23.

[0027] The inner wall of the mounting sleeve 17 has a limiting groove 18. A limiting protrusion 20 is fixedly connected to the side wall of the limiting block 19 away from the screw 16. The limiting protrusion 20 is slidably connected to the limiting groove 18. The diameter of the screw 16 is smaller than the diameter of the limiting block 19. During operation, when it is necessary to adjust the spraying angle, the screw 16 is rotated to drive the limiting block 19 to rotate. The limiting protrusion 20 rotates accordingly and slides along the limiting groove 18. Under the sliding cooperation between the limiting protrusion 20 and the limiting groove 18, the mounting sleeve 17 rotates in the rotating groove 15. The mounting sleeve 23 drives the clamping assembly to rotate together, which makes it convenient for the operator to adjust the angle of the steel component as needed to adapt to the spraying operation. The threaded locking force between the screw 16 and the threaded groove 14 ensures that the mounting sleeve 17 will not deviate or rotate back after rotation.

[0028] The clamping assembly includes a second lead screw 25 and a clamping plate 28. The second lead screw 25 is rotatably connected to the inner cavity of the second mounting sleeve 23. The top end of the second lead screw 25 extends above the second mounting sleeve 23. The second lead screw 25 has symmetrical double threads with opposite directions of rotation. The second mounting sleeve 23 has two symmetrically opened slots 24. The second lead screw 25 has two threaded sleeves 26 connected symmetrically by threads. A slider 27 is fixedly connected to the threaded sleeve 26. The end of the slider 27 away from the threaded sleeve 26 extends to the outside of the second mounting sleeve 23 and is fixedly connected to the clamping plate 28. The slider 27 is slidably connected to the slot 24. During operation, rotating the second lead screw 25 can drive the two threaded sleeves 26 to move towards or away from each other, so that the slider 27 slides along the slot 24 and drives the two clamping plates 28 to move closer or further away, which makes it convenient for the operator to adjust the distance between the two clamping plates 28 according to the thickness of the steel component.

[0029] A scale 21 is fixedly connected to the outer wall of the lifting seat 11 near the second mounting sleeve 23. Two pointers 22 are symmetrically fixed to the outer wall of the first mounting sleeve 17. The pointers 22 are in contact with the scale 21. During operation, when the first mounting sleeve 17 rotates, the pointers 22 rotate accordingly. The angle of the pointers 22 after rotation corresponds to the angle on the scale 21, which makes it easier for the operator to adjust the rotation angle more accurately.

[0030] Working principle: Workers can start motor 6 according to the height of the steel component. Motor 6 drives the rotating shaft 7 to rotate, causing the synchronous pulley 8 and synchronous belt 9 to drive the lead screw 10 to rotate. This, in turn, causes the lead sleeve 13 to move the lifting seat 11 on the guide rod 5, facilitating quick adjustment by workers according to the dimensions of the steel component. After adjusting the height of the lifting seat 11, rotating the lead screw 25 causes the two lead sleeves 26 to move in opposite directions, causing the slider 27 to slide along the opening slot 24 and move the two clamping plates 28 closer or further apart. This allows workers to adjust the distance between the two clamping plates 28 according to the thickness of the steel component. The adjustment is performed to clamp and fix both ends of the steel component. When the spraying angle of the steel component needs to be adjusted during the spraying process, the screw 16 is rotated to drive the limiting block 19 to rotate. The limiting protrusion 20 rotates and slides along the limiting groove 18. Under the sliding cooperation between the limiting protrusion 20 and the limiting groove 18, the first mounting sleeve 17 rotates in the rotating groove 15. The second mounting sleeve 23 drives the clamping assembly to rotate together, which makes it easy for the staff to adjust the angle of the steel component as needed to adapt to the spraying operation. This ensures that the side of the steel component that is not sprayed can be accurately aligned with the spray gun 2 after rotation adjustment, ensuring the uniform thickness of the coating.
