Description

Technical Field

[0001] This utility model relates to the field of painting equipment technology, and in particular to a painting equipment for automobile shock absorbers. Background Technology

[0002] Shock absorber spraying is a key step in the production and processing of automotive shock absorbers. Its core purpose is to improve the appearance quality of the shock absorbers by coating them with paint or other coatings, while forming a protective film to enhance their resistance to corrosion and wear, thereby extending their service life.

[0003] During the spraying process, it is necessary to ensure that the paint evenly covers all surfaces of the shock absorber, including complex structural parts, to ensure consistent protective effect.

[0004] A search revealed that Chinese patent application number 202421855943.8 discloses a painting device for shock absorbers in new energy vehicles, including a chamber and a painting system located on one side thereon. The painting system is connected to a paint spraying pipe via a connecting pipe. The paint spraying pipe has a C-shaped structure, and several nozzles are arranged on opposite sides of two horizontal sections. A workpiece basket is arranged between the two sets of nozzles, and a return hole is provided at the bottom of the workpiece basket. A moving component is also provided at the bottom of the workpiece basket. In this invention, the shock absorber is placed in the workpiece basket. A linear drive mechanism a drives the sliding cover to move and cooperates with the sealing cover to close the chamber and prevent paint mist from overflowing. A linear drive mechanism b drives the workpiece basket to move horizontally back and forth. The painting system sprays paint onto the surface of the shock absorber through the paint spraying pipe and nozzles. During this process, excess paint can be returned to the recycling tank through a filtration mechanism. At the same time, an air purifier extracts the gas in the chamber and purifies and filters it before the sealing cover is opened, minimizing paint pollution.

[0005] Regarding the aforementioned technology, the applicant believes that because the models of shock absorbers are different, the lengths of the shock absorbers are also different. During painting, the spraying range of the spray gun is limited. For large-sized shock absorbers, it is necessary to remove and adjust the position of the shock absorber twice in order to complete the painting, which reduces the painting efficiency. In addition, in some existing painting equipment, because the position of the shock absorber is fixed during the painting process, it is difficult to ensure that all surfaces of the shock absorber can be evenly contacted with the paint, which easily leads to uneven painting and affects the coating quality of the shock absorber.

The rotating structure includes a mounting plate, a rotating rod, and a driven bevel gear. The lower end of the mounting plate is fixedly connected to the upper surface of the support plate. A through hole is opened on the upper surface of the support plate. A rotating rod is rotatably connected inside the through hole on the upper surface of the support plate. A driven bevel gear is fixedly connected to the upper end of the rotating rod. A transmission bevel gear meshes above the driven bevel gear. A first servo motor is provided at one end of the transmission bevel gear. The power output end of the first servo motor is fixedly connected to one end of the transmission bevel gear. The first servo motor is fixedly connected to the upper surface of the mounting plate.

[0008] Preferably, a paint spray nozzle is installed on the inner wall of the paint spray chamber, and a paint spraying assembly is provided on the outer side of the paint spray chamber. The paint spraying assembly is installed on the upper surface of the base, and the paint spraying assembly is connected to the paint spray nozzle on the inner wall of the paint spray chamber.

[0009] Preferably, a partition is fixedly connected to the inner wall of the first guide rail, a through hole is provided on the upper surface of the partition, and a second servo motor is provided below the partition, the second servo motor being fixedly connected to the inner wall of the first guide rail.

[0010] Preferably, the upper end of the first sliding block is provided with a threaded hole, and a threaded rod is threadedly connected inside the threaded hole at the upper end of the first sliding block. The upper end of the threaded rod is rotatably connected to the top of the first guide rail, and the lower end of the threaded rod is rotatably connected to the inside of the through hole on the upper surface of the partition plate. The lower end of the threaded rod passes through the through hole on the upper surface of the partition plate and is fixedly connected to the power output end of the first servo motor.

[0011] Preferably, the upper end of the second sliding block has a through hole, and a sliding rod is slidably connected inside the through hole at the upper end of the second sliding block. The upper and lower ends of the sliding rod are respectively fixedly connected to the top and bottom of the second guide rail.

[0012] Preferably, the upper surface of the support plate has a through hole, and the lower surface of the support plate has a hook. The upper end of the hook is rotatably connected to the inside of the through hole on the upper surface of the support plate, and the upper end of the hook passes through the through hole on the upper surface of the support plate and is fixedly connected to the lower end of the rotating rod.

[0013] Compared with related technologies, the automotive shock absorber painting equipment provided by this utility model has the following beneficial effects:

[0014] 1. By setting up a support plate and a lifting structure, the rotation of the second servo motor's power output end drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the threaded hole at the upper end of the first sliding block, and the first sliding block slides in the first guide rail, the rotational motion of the threaded rod is converted into the linear lifting motion of the first sliding block. At the same time, the second sliding block, which is connected to the first sliding block through the lifting rod, slides synchronously along the slide rod in the second guide rail. The lifting rod transmits the lifting motion of the first and second sliding blocks to the support plate, causing the support plate, along with the rotating structure and the shock absorber on the hook, to descend into the paint booth at a suitable painting height position. There is no need to remove and adjust the position of the shock absorber again, which effectively improves the painting efficiency.

[0015] 2. With a rotating structure, the first servo motor's power output rotates, driving the transmission bevel gear to rotate. The transmission bevel gear meshes with the driven bevel gear, thereby driving the driven bevel gear to rotate. The driven bevel gear is fixed to the upper end of the rotating rod, which in turn drives the rotating rod to rotate within the through hole on the upper surface of the bearing plate. The lower end of the rotating rod is fixedly connected to the hook, ultimately causing the shock absorber on the hook to start rotating. At the same time, the paint spraying assembly outside the paint spraying chamber operates, conveying paint through the connecting structure to the paint spraying nozzle on the inner wall of the paint spraying chamber. The paint spraying nozzle atomizes the paint and sprays it onto the surface of the rotating shock absorber, ensuring that all surfaces of the shock absorber can evenly contact the atomized paint, significantly improving the painting quality of the shock absorber.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes: a base 1, a mounting frame 2, a paint spray chamber 3, a support plate 4, a lifting structure 5, and a rotating structure 6. The base 1 serves as the fundamental support component for the entire equipment, providing a stable mounting platform for all structures above and ensuring overall stability during operation. The mounting frame 2 is fixedly connected to the upper surface of the base 1, connecting and supporting the paint spray chamber 3, thus securing it firmly above the base 1 and ensuring a secure installation position. The paint spray chamber 3 is fixedly connected to the inner wall of the mounting frame 2. The paint spray chamber 3 provides a closed working space for painting automotive shock absorbers, preventing paint mist from spreading to the outside during the painting process and creating a relatively stable painting environment. A support plate 4 is installed at the top of the paint spray chamber 3. 4 is used to install and support the rotating structure 6, providing a stable installation foundation for the rotating structure 6. A lifting structure 5 is provided on the lower surface of the bearing plate 4. The lifting structure 5 can drive the bearing plate 4, the rotating structure 6 above it, and the shock absorber to be painted to move up and down, thereby adjusting the height of the shock absorber within the paint spray chamber 3 to achieve the optimal painting position. The lifting structure 5 includes a first guide rail 7, a second guide rail 8, a first sliding block 9, a second sliding block 10, and a lifting rod 11. The first guide rail 7 and the second guide rail 8 provide guidance for the sliding of the first sliding block 9 and the second sliding block 10, ensuring the stability and accuracy of the sliding block movement. The first guide rail 7 and the second guide rail 8 are fixedly connected to the inner wall of the paint spray chamber 3. The first sliding block 9 is internally slidably connected to the first guide rail 7, and the second sliding block 10 is internally slidably connected to the second guide rail 8. The first sliding block 9 and the second sliding block 10 can slide within the first guide rail 7 and the second guide rail 8 respectively, thereby driving the lifting rod 11 to move up and down. The lifting rod 11 is fixedly connected to one side of both the first sliding block 9 and the second sliding block 10. The lifting rod 11 is a key component connecting the sliding block and the support plate 4. The movement of the sliding block is transmitted to the support plate 4 through the lifting rod 11, realizing the lifting and lowering of the support plate 4. The upper end of the lifting rod 11 is fixedly connected to the lower surface of the support plate 4. The upper surface of the support plate 4 is provided with a rotating structure 6. The rotating structure 6 can drive the car shock absorber to be painted to rotate, so that all surfaces of the shock absorber are painted. The rotating structure 6, which ensures uniform paint mist contact and paint spraying, includes a mounting plate 12, a rotating rod 13, and a driven bevel gear 14. The mounting plate 12 provides support for the first servo motor 16 and the rotating rod 13, ensuring the stability of the components. The lower end of the mounting plate 12 is fixedly connected to the upper surface of the support plate 4. A through hole is provided on the upper surface of the support plate 4, providing space for the installation and rotation of the rotating rod 13, allowing it to pass through the support plate 4 to connect the upper and lower components. The rotating rod 13 is rotatably connected inside the through hole on the upper surface of the support plate 4. The rotating rod 13 transmits power, transferring the rotation of the driven bevel gear 14 to the hook 23 below, which in turn drives the shock absorber to rotate.A driven bevel gear 14 is fixedly connected to the upper end of the rotating rod 13. The driven bevel gear 14 meshes with the transmission bevel gear 15 and rotates under the drive of the transmission bevel gear 15, thereby transmitting the power of the first servo motor 16 to the rotating rod 13. The transmission bevel gear 15 meshes above the driven bevel gear 14 and rotates under the drive of the first servo motor 16. Through meshing with the driven bevel gear 14, the transmission bevel gear 15 drives the driven bevel gear 14 to rotate, thus realizing the transmission of power. The first servo motor 16 is provided at one end of the transmission bevel gear 15. The first servo motor 16 is... The rotating structure 6 provides the power source, driving the transmission bevel gear 15 to rotate, thus rotating the entire rotating structure 6. The power output end of the first servo motor 16 is fixedly connected to one end of the transmission bevel gear 15. The first servo motor 16 is also fixedly connected to the upper surface of the mounting plate 12. The first servo motor 16 is electrically connected to an external power supply and a PLC controller. The PLC controller is used to set the control program and control the start and stop of the first servo motor 16 and the forward and reverse rotation of the power output end of the first servo motor 16. The PLC controller is a commonly used and mature technology, and will not be described in detail here.

[0023] In the specific implementation process, a paint spray nozzle 17 is installed on the inner wall of the paint spray chamber 3. The paint spray nozzle 17 is a component that atomizes the paint and sprays it onto the surface of the shock absorber, directly realizing the painting operation. A paint spray assembly 18 is set on the outside of the paint spray chamber 3. The paint spray assembly 18 is existing technology and will not be described in detail here. The paint spray assembly 18 provides paint and power to the paint spray nozzle 17 and is responsible for conveying the paint to the paint spray nozzle 17 and atomizing it. The paint spray assembly 18 is installed on the upper surface of the base 1 and is interconnected with the paint spray nozzle 17 on the inner wall of the paint spray chamber 3. The interconnection structure ensures that the paint can be smoothly conveyed from the paint spray assembly 18 to the paint spray nozzle 17.

[0024] The first guide rail 7 has a partition 19 fixedly connected to its inner wall. The partition 19 is used to separate the internal space of the first guide rail 7, provide an installation position for the second servo motor 20, and provide certain support and limiting function for the threaded rod 21. The upper surface of the partition 19 has a through hole, which provides a channel for the threaded rod 21 to pass through, so that the threaded rod 21 can connect the second servo motor 20 and the first sliding block 9. The second servo motor 20 is arranged below the partition 19. The second servo motor 20 provides power to the lifting structure 5, drives the threaded rod 21 to rotate, and then drives the first sliding block 9 to move. The second servo motor 20 is fixedly connected to the inner wall of the first guide rail 7. The second servo motor 20 is electrically connected to an external power supply and a PLC controller. The PLC controller is used to set the control program and control the start and stop of the second servo motor 20 and the forward and reverse rotation of the power output terminal of the second servo motor 20. The PLC controller is a commonly used and mature technology, and will not be described in detail here.

[0025] The first sliding block 9 has a threaded hole at its upper end, which engages with a threaded rod 21. When the threaded rod 21 rotates, it drives the first sliding block 9 to slide up and down within the first guide rail 7 via threaded transmission. The threaded rod 21 is threadedly connected inside the threaded hole at the upper end of the first sliding block 9. Driven by the second servo motor 20, the threaded rod 21 rotates and, through its threaded engagement with the first sliding block 9, converts the rotational motion into the linear lifting motion of the first sliding block 9. The upper end of the threaded rod 21 is rotatably connected to the top of the first guide rail 7, and the lower end of the threaded rod 21 is rotatably connected to the through hole on the upper surface of the partition 19. The lower end of the threaded rod 21 passes through the through hole on the upper surface of the partition 19 and is fixedly connected to the power output end of the second servo motor 20, ensuring that the threaded rod 21 can rotate stably and transmit the power of the second servo motor 20 to the first sliding block 9.

[0026] The second sliding block 10 has a through hole at its upper end, which cooperates with the slide rod 22 to allow the second sliding block 10 to slide stably along the slide rod 22. The slide rod 22 is slidably connected inside the through hole at the upper end of the second sliding block 10. The slide rod 22 guides and limits the sliding of the second sliding block 10, ensuring that the second sliding block 10 remains stable during the lifting and lowering process and moves synchronously with the first sliding block 9. The upper and lower ends of the slide rod 22 are fixedly connected to the top and bottom of the second guide rail 8, respectively.

[0027] The upper surface of the support plate 4 has a through hole, which provides a channel for the connection between the hook 23 and the rotating rod 13, so that the rotating rod 13 can drive the hook 23 to rotate. The lower surface of the support plate 4 is provided with a hook 23, which is used to suspend the car shock absorber to be painted and is a component for fixing the shock absorber. The upper end of the hook 23 is rotatably connected to the inside of the through hole on the upper surface of the support plate 4, and the upper end of the hook 23 passes through the through hole on the upper surface of the support plate 4 and is fixedly connected to the lower end of the rotating rod 13, so that the rotation of the rotating rod 13 can directly drive the hook 23 and the shock absorber on the hook 23 to rotate.

[0028] The working principle of this utility model is as follows: First, the car shock absorber to be painted is suspended on the hook 23 on the lower surface of the support plate 4. The hook 23 is connected to the rotating structure 6 by a fixed connection between its upper end and the lower end of the rotating rod 13. The base 1 serves as the basic support for the entire equipment, ensuring the stable installation of all the upper structures such as the mounting frame 2 and the paint spraying chamber 3. Next, the external power supply is connected, and the control program is set through the PLC controller. When the equipment is started, the PLC controller controls the second servo motor 20 to start. The power output end of the second servo motor 20 rotates, driving the threaded rod 21 to rotate. Since the threaded rod 21 is threadedly connected to the threaded hole at the upper end of the first sliding block 9... The first sliding block 9 slides within the first guide rail 7, converting the rotational motion of the threaded rod 21 into the linear lifting motion of the first sliding block 9. Simultaneously, the second sliding block 10, connected to the first sliding block 9 via the lifting rod 11, slides synchronously along the sliding rod 22 within the second guide rail 8. The lifting rod 11 transmits the lifting motion of the first sliding block 9 and the second sliding block 10 to the support plate 4, causing the support plate 4, along with the rotating structure 6 and the shock absorber on the hook 23, to descend into the appropriate spraying height position within the paint spraying chamber 3. Subsequently, the PLC controller controls the first servo motor 16 to start, and the rotation of the power output end of the first servo motor 16 drives the transmission bevel gear 15 to rotate, thus transmitting... Bevel gear 15 meshes with driven bevel gear 14, thereby driving driven bevel gear 14 to rotate. Driven bevel gear 14 is fixed to the upper end of rotating rod 13, which in turn drives rotating rod 13 to rotate within the through hole on the upper surface of bearing plate 4. The lower end of rotating rod 13 is fixedly connected to hook 23, ultimately driving the shock absorber on hook 23 to start rotating. At the same time, the paint spraying assembly 18 on the outside of paint tank 3 works, conveying paint through the connecting structure to the paint spray nozzle 17 on the inner wall of paint tank 3. The paint spray nozzle 17 atomizes the paint and sprays it onto the surface of the rotating shock absorber. Because the shock absorber rotates continuously under the drive of rotating structure 6 and is at the optimal height adjusted by lifting structure 5, The positioning ensures that all surfaces of the shock absorber can evenly contact the atomized paint, completing a uniform painting operation. During the painting process, the paint spray chamber 3 provides a closed space to prevent paint mist from spreading, while the mounting bracket 2 always stably supports the paint spray chamber 3. The partition 19 provides support and limit for the second servo motor 20 and the threaded rod 21 in the first guide rail 7, ensuring stable linkage of all components. After the painting is completed, the PLC controller controls the first servo motor 16 and the painting assembly 18 to stop working, and at the same time controls the second servo motor 20 to rotate in the opposite direction. Through the linkage of the threaded rod 21, the sliding block, and the lifting rod 11, the bearing plate 4 and the shock absorber are driven to rise, making it easy to remove the painted shock absorber.
