Detailed Implementation

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an automatic spraying device for fastener surface treatment, including a workbench 1. A spraying groove 3 is provided on the top of the workbench 1 to accommodate excess spraying material and prevent contamination of the working environment. Fixed plates 4 are fixedly connected to the front and rear sides of the top of the workbench 1, serving as support structures for components such as a motor 5 and a rotating rod 6. A motor 5 is fixedly connected to the front side of the front fixed plate 4, providing power for the rotation of the rotating rod 6. The output end of the motor 5 passes through the fixed plate 4 and is fixedly connected to the rotating rod 6, transmitting the rotational motion of the motor 5 to a clamping frame 7. A rotating rod 6 is rotatably connected to the front side of the rear fixed plate 4, enabling the two rotating rods 6 to rotate collaboratively. The same clamping frame 7 is fixedly connected to adjacent ends of the two rotating rods 6 for mounting and fixing clamping components. Sliding grooves 8 are provided on the left and right sides of the inner wall of the clamping frame 7, providing sliding tracks for sliding blocks 9. Both ends of the two sliding grooves 8 slide within each other. A sliding block 9 is connected to the clamping plate 11, which can be adjusted laterally. Telescopic rods 10 are fixedly connected to both ends of the inner wall of the clamping frame 7 to adjust the position of the clamping plate 11. One end of each telescopic rod 10 is fixedly connected to a corresponding clamping plate 11, which can clamp or loosen fasteners of different sizes. The two ends of the two clamping plates 11 are fixedly connected to one side of the corresponding sliding block 9, so that the movement of the clamping plate 11 is coordinated with the sliding block 9. A spraying mechanism 2 is provided on the rear side of the worktable 1 for spraying the fasteners. The upper and lower sides of the two sliding grooves 8 are provided with grooves 18 to guide the movement of the slider 19. The upper and lower sides of the multiple sliding blocks 9 are fixedly connected to sliders 19, which helps the sliding blocks 9 slide more smoothly in the sliding grooves 8. The multiple sliders 19 are slidably connected to the interior of the corresponding grooves 18 to ensure that the sliding blocks 9 do not shift up and down during the sliding process.

[0033] Specifically, when surface coating is required on the fasteners, the sliding grooves 8 on the left and right sides of the inner wall of the clamping frame 7 provide sliding tracks for the sliding blocks 9. The sliding blocks 9 at both ends of the sliding groove 8 can slide flexibly within the groove. Meanwhile, the multiple telescopic rods 10 fixedly connected to the front and rear ends of the inner wall of the clamping frame 7 play a crucial role. One end of each telescopic rod 10 is fixedly connected to a clamping plate 11, and the two clamping plates 11 are respectively fixedly connected to one side of the corresponding sliding block 9. During operation, the telescopic rods 10 can extend and retract, causing the clamping plates 11 to adjust their position. The sliding of the sliding blocks 9 within the sliding grooves 8 further assists the clamping plates 11 in adjusting their position, allowing the two clamping plates 11 to accommodate fasteners of different sizes and place the fasteners... At a suitable position, the positions of the two clamping plates 11 are adjusted by the extension and retraction of the telescopic rod 10 and the sliding of the sliding block 9 in the sliding groove 8, so that they can firmly clamp the fastener. Then, the motor 5 is started, driving the rotating rod 6 to rotate, so that the clamping frame 7 and the fastener clamped inside it rotate together. During the rotation, the surface of the fastener can be evenly sprayed by the spraying device that cooperates with the spraying groove 3. Since the fastener rotates continuously under the drive of the clamping frame 7, the uniformity and efficiency of the spraying are greatly improved, avoiding the unevenness and omissions that may occur during manual operation. When the sliding block 9 slides in the sliding groove 8, the cooperation of the slider 19 and the sliding groove 18 can ensure that the sliding block 9 slides more smoothly and steadily, and at the same time, it plays a limiting role for the sliding block 9.

[0034] Reference Figure 1 , Figure 4 and Figure 5The spraying mechanism 2 includes an L-shaped plate 201. The front bottom of the L-shaped plate 201 is fixedly connected to the rear side of the workbench 1, allowing the spraying mechanism 2 to be stably installed on the workbench 1. Telescopic rods 202 are fixedly connected to the left and right sides of the inner top wall of the workbench 1, which can be used to adjust the vertical position of the horizontal plate 203. The other ends of both telescopic rods 202 are fixedly connected to the same horizontal plate 203, which supports subsequent moving parts and the spray nozzle 208. A moving groove 204 is provided at the bottom of the horizontal plate 203, providing installation space for components such as the moving block 206 and the telescopic rod 205. The left end of the inner side of the moving groove 204 is fixedly connected to the telescopic rod 205, which can be pushed... The movable block 206 moves horizontally within the movable groove 204. One end of the telescopic rod 205 is fixedly connected to the movable block 206, which drives the connecting plate 207 and the nozzle 208 to adjust their horizontal position. The bottom of the movable block 206 is fixedly connected to the connecting plate 207 for connecting the nozzle 208. Multiple nozzles 208 are fixedly connected at equal intervals to the bottom of the connecting plate 207, which can spray paint onto the surface of the fastener. Limiting grooves 20 are provided on the front and rear sides of the interior of the movable groove 204 to guide and limit the movement of the limiting block 21. Limiting blocks 21 are fixedly connected to the front and rear sides of the movable block 206 to prevent the movable block 206 from shifting back and forth during the movement.

[0035] Specifically, based on the size of the fastener to be sprayed and the spraying requirements, the height of the horizontal plate 203 and the nozzle 208 is adjusted by the telescopic rod 202 to achieve a suitable distance between the nozzle 208 and the fastener. Then, by extending and retracting the telescopic rod 305, the moving block 206 moves within the moving groove 204, causing the nozzle 208 to move left and right, thereby expanding the spraying coverage of the nozzle 208. Once the nozzle 208 is in the correct position, the spraying operation can begin. Multiple nozzles 208 will evenly spray the paint onto the surface of the fastener. As the telescopic rod 305 moves the moving block 206 left and right within the moving groove 204, the limiting block 21 slides within the limiting groove 20, restricting the movement range of the moving block 206 and preventing it from detaching from the moving groove 204 due to excessive movement.

[0036] Reference Figure 1 , Figure 2 and Figure 3A switch 12 is fixedly connected to the front side of the workbench 1. The switch 12 controls the extension and retraction of the first telescopic rod 10 to adjust the position of the clamping plate 11. The switch 12 is electrically connected to the first telescopic rod 10, the motor 5, the second telescopic rod 202, and the third telescopic rod 205, respectively. It can control the start and stop of the motor 5, thereby controlling the rotation of the clamping frame 7. At the same time, it can control the extension and retraction of the second telescopic rod 202 and the third telescopic rod 205 to adjust the position of the nozzle 208. Support feet 13 are fixedly connected to the four corners of the bottom of the workbench 1. The support feet 13 are used to support the entire workbench 1 and make the device stable. Rubber pads 14 are fixedly connected to the bottom of the multiple support feet 13. The rubber pads 14 can increase the stability of the device. The friction between the support foot 13 and the ground is increased to prevent the device from sliding during operation and to provide a certain buffering effect. Triangular plates 15 are fixedly connected to the bottom of the left and right sides of the L-shaped plate 201. The triangular plates 15 can enhance the connection strength between the L-shaped plate 201 and the workbench 1 and ensure the stability of the spraying mechanism 2. The front sides of the two triangular plates 15 are fixedly connected to the rear side of the workbench 1 to ensure a firm connection. The adjacent sides of the two fixed plates 4 are fixedly connected to the rings 16. The rings 16 can provide auxiliary support and positioning for the rotation of the clamping frame 7. The front and rear ends of the clamping frame 7 are provided with arc grooves 17. The arc grooves 17 can cooperate with the rings 16 to guide the rotation of the clamping frame 7 and make its rotation more stable.

[0037] Specifically, the user can turn the motor 5 on or off via switch 12, thereby controlling the rotation of the clamping frame 7 to allow the fastener to rotate for uniform spraying. This provides support and stability to the entire automatic fastener surface treatment spraying device, ensuring the device remains stable during operation. Multiple support feet 13 are evenly distributed at the four corners, allowing the weight of the worktable 1 to be evenly distributed, enhancing the connection strength between the L-shaped plate 201 and the worktable 1, and preventing damage during device operation. This ensures the stability and reliability of the spraying mechanism 2 during operation, thus guaranteeing the smooth progress of the entire spraying process. When the clamping frame 7 rotates, the ring 16 and the arc-shaped groove 17 cooperate to limit and guide the rotation of the clamping frame 7.

[0038] Working principle: When surface coating is required on fasteners, the sliding grooves 8 on the left and right sides of the inner wall of the clamping frame 7 provide sliding tracks for the sliding blocks 9. The sliding blocks 9 at both ends of the sliding groove 8 can slide flexibly within the groove. At the same time, the multiple telescopic rods 10 fixedly connected to the front and rear ends of the inner wall of the clamping frame 7 play an important role. One end of the telescopic rod 10 is fixedly connected to the clamping plate 11, and the two ends of the clamping plates 11 are respectively fixedly connected to one side of the corresponding sliding block 9. In this way, during operation, the telescopic rods 10 can extend and retract, driving the clamping plates 11 to adjust their position. The sliding of the sliding blocks 9 in the sliding groove 8 further assists the clamping plates 11 in adjustment. The position of the two clamping plates 11 is adjusted so that they can accommodate fasteners of different sizes. The fastener is placed in a suitable position, and the position of the two clamping plates 11 is adjusted by the extension and retraction of the telescopic rod 10 and the sliding block 9 in the sliding groove 8 so that the fastener can be firmly clamped. Then the motor 5 is started, driving the rotating rod 6 to rotate, so that the clamping frame 7 and the fasteners clamped inside it rotate together. During the rotation, the surface of the fastener can be evenly sprayed by the spraying device that cooperates with the spraying groove 3. Since the fastener rotates continuously under the drive of the clamping frame 7, the uniformity and efficiency of the spraying are greatly improved, and the unevenness and omissions that may occur during manual operation are avoided.

[0039] Furthermore, based on the size of the fastener to be sprayed and the spraying requirements, the height of the horizontal plate 203 and the nozzle 208 is adjusted by the telescopic rod 202 to achieve a suitable distance between the nozzle 208 and the fastener. Then, by extending and retracting the telescopic rod 305, the moving block 206 moves within the moving groove 204, causing the nozzle 208 to move left and right, thereby expanding the spraying coverage of the nozzle 208. Once the nozzle 208 is in the correct position, the spraying operation can begin, and multiple nozzles 208 will evenly spray the paint onto the surface of the fastener.

Although the present 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.
