[0002] A spring is a mechanical part that works using elasticity. A part made of elastic material deforms under an external force and returns to its original shape after the external force is removed. Generally, it is made of spring steel. Spring spraying is a surface treatment process. After spraying on the spring surface, a protective coating is formed on the surface to improve its corrosion resistance, wear resistance and aesthetics. This treatment method is widely used in spring production to extend the service life of the spring and maintain its performance stability.

[0003] A spring surface spraying device disclosed in the Chinese Patent Application Publication Specification CN220294991U. When the device sprays the spring, it makes the inner side of the spring sprayed more evenly, so that the quality of the produced spring is maintained at a high level. Through the mutual cooperation of the button, the lever arm and the first motor, the operator does not have to operate in a small box when placing and taking the spring, realizing automatic operation, and the machine cannot rotate after rotating the lever arm, ensuring the accuracy of the rotation position and the stability of the equipment.

[0004] However, in the process of implementing the technical solution of the above patent, the spraying effect cannot be guaranteed at the contact position between the spring and the hook. Before spraying the spring, the existing spraying device will first fix the spring through a hook or a clamping claw. However, the coating material cannot adhere to the contact position between the spring and the hook or the clamping claw during the subsequent spraying, so that there is no protective coating at some positions of the spring, affecting the service life of the spring.

[0029] Please refer specifically to Figure 1 , Figure 3 , Figure 4 and Figure 5 , including a base 1. Above the base 1, there are two symmetrically arranged driving mechanisms 2. The driving mechanism 2 includes a support base 21. The outer surface of the support base 21 is rotatably connected with a rotating cylinder 22.

[0030] Two symmetrically arranged first hinge rods 26 are hinged on the outer surface of the connecting plate 25. One end of the first hinge rod 26 far from the connecting plate 25 is hinged on the outer surface of the anti - detachment slider 23. When the first electric push rod 24 expands and contracts, it can drive the two anti - detachment sliders 23 connected to the first hinge rods 26 to move away from or close to each other. The first electric push rods 24 in the two driving mechanisms 2 share the same controller.

[0031] The outer surface of the support base 21 is fixedly connected with a second electric push rod 27. The second electric push rods 27 in the two driving mechanisms 2 share the same controller. The telescopic end of the second electric push rod 27 is fixedly connected with an annular connecting frame 28.

Two of the four anti - detachment sliders 23 are respectively connected to the two first hinge rods 26, and the other two anti - detachment sliders 23 are respectively connected to the two second hinge rods 211. When the second electric push rod 27 expands and contracts, it can drive the two anti - detachment sliders 23 connected to the second hinge rods 211 to move away from or close to each other.

[0033] The outer surface of the support base 21 is fixedly connected with a first motor 212. The output shaft end of the first motor 212 is fixedly connected with a driving gear 213.

When the first motor 212 operates, under the meshing action of the driving gear 213 and the driven gear ring 214, the first motor 212 can drive the rotating cylinder 22 to rotate.

[0035] Please refer particularly to Figure 2 and Figure 3 , four bearing rods 5 and four clamping seats 6 are arranged inside the base 1. The bearing rods 5 and the clamping seats 6 are adapted to each other. One end of the bearing rod 5 can be stuck inside the clamping seat 6. Both the bearing rod 5 and the clamping seat 6 are adapted to the anti - detachment slider 23. The two driving mechanisms 2 are respectively connected to the bearing rod 5 and the clamping seat 6. The bearing rod 5 and the clamping seat 6 are respectively fixed on the anti - detachment sliders 23 of different driving mechanisms 2. And the support seat 21 on the bearing rod 5 is fixed on the upper surface of the base 1, while the support seat 21 on the clamping seat 6 is fixed on the internally - threaded moving block 32.

[0036] Please refer particularly to Figure 1 and Figure 2 , a moving mechanism 3 is arranged inside the base 1. The moving mechanism 3 includes a threaded rod 31 rotatably connected to the inner wall of the base 1. An internally - threaded moving block 32 is threadedly connected to the outer surface of the threaded rod 31. The internally - threaded moving block 32 is slidably connected to the inner wall of the base 1. Among the two support seats 21, the support seat 21 close to the internally - threaded moving block 32 is fixedly connected to the upper surface of the internally - threaded moving block 32. The support seat 21 on the clamping seat 6 is fixed on the internally - threaded moving block 32, so that the movement of the internally - threaded moving block 32 can drive the clamping seat 6 to move.

[0037] The above - mentioned moving mechanism 3 further includes a second motor 33 fixedly connected to the outer surface of the base 1. One end of the threaded rod 31 close to the second motor 33 penetrates through the base 1 and extends to the outside of the base 1. One end of the threaded rod 31 close to the second motor 33 is fixedly connected to the output shaft end of the second motor 33. The second motor 33 provides power for the rotation of the threaded rod 31.

[0038] Please refer particularly to Figure 1 , a spraying mechanism 4 is arranged above the base 1. The spraying mechanism 4 includes a protective cover 41 fixedly connected to the upper surface of the base 1. The inner top wall of the protective cover 41 is fixedly connected with a support frame 42. The outer surface of the support frame 42 is fixedly connected with a plurality of spray nozzles 43 arranged at equal intervals. A paint tank and an air pump are arranged on the protective cover 41, so that the spray nozzles 43 can spray paint onto the spring.

[0039] Working principle: Control the operation of the second motor 33 to rotate the threaded rod 31, drive the internally threaded moving block 32, the support base 21 and the clamping seat 6 away from the bearing rod 5, and then multiple springs can be sleeved on the bearing rod 5. Control both the first electric push rod 24 and the second electric push rod 27 to extend, so that the connecting plate 25 and the annular connecting frame 28 both move towards the anti-slip block 23. Under the action of the first hinge rod 26 and the second hinge rod 211, the four anti-slip blocks 23 all move outwards. At this time, the four bearing rods 5 are all fixed to the springs. Then control the two first electric push rods 24 to shorten synchronously, drive the connecting plate 25 away from the anti-slip block 23, and drive the two anti-slip blocks 23 connected to the first hinge rod 26 to approach each other through the first hinge rod 26, so that the two bearing rods 5 and the two clamping seats 6 on the anti-slip block 23 connected to the first hinge rod 26 approach each other. At this time, control the nozzle 43 to spray the springs;

[0040] Then make the two first electric push rods 24 extend synchronously, so that the two bearing rods 5 and the two clamping seats 6 on the anti-slip block 23 connected to the first hinge rod 26 move away from each other, and connect the bearing rod 5 to the spring. Control the two second electric push rods 27 to shorten synchronously, and the annular connecting frame 28, the annular anti-slip rotating frame 29 and the fixing frame 210 all move away from the anti-slip block 23. The other two anti-slip blocks 23 will be driven to approach each other through the second hinge rod 211, so that the two bearing rods 5 and the two clamping seats 6 on the anti-slip block 23 connected to the second hinge rod 211 approach each other. These two bearing rods 5 do not contact the springs, and continue to spray the springs. At the same time, ensure the operation of the first motor 212 to rotate the rotating cylinder 22, the bearing rod 5 and the springs, and ensure that all positions on the surface of the springs are sprayed. This device can make the springs alternately contact two of the four bearing rods 5, avoiding that the contact positions cannot be sprayed, so as to ensure that all positions on the surface of the springs can be sprayed.
