[0002] Automotive shock absorbers are one of the core components of the suspension system. Their main function is to suppress the rebound impact after the springs absorb the shock and the vibration from road bumps, ensuring the stability and comfort of the vehicle. During manufacturing, automotive shock absorbers undergo a coating process to achieve good protection and extend their service life.

[0003] The authorized publication number is CN217450709U, entitled "A High-Efficiency Spraying Device for Shock Absorber Production." It mentions that "multiple shock absorber housings are mounted on multiple hanging pipes 5. The drive unit is controlled to drive the rotating drum 3 to rotate, which in turn drives the auxiliary gear 4 fixed to the rotating drum 3 to rotate, which drives the gear ring 2 to rotate, which in turn drives other auxiliary gears 4 to rotate, thereby driving multiple rotating drums 3 to rotate. The hanging pipes 5 and the shock absorber housings on them rotate slowly. At this time, the spraying unit starts to work and sprays the rotating shock absorber housings comprehensively." Because the dimensions of the hanging pipes 5 are uniformly set, and when the housing is suspended on the hanging pipes 5, there is no positioning mechanism to fix it, which will inevitably cause swaying during rotation, resulting in uneven spraying on the outer wall of the housing and affecting the processing effect.

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1 to 5 This utility model provides a high-efficiency spraying device for automobile shock absorber production, including a spraying box 1 and a base 2 connected to the bottom of the inside of the spraying box 1. The base 2 is connected to multiple columns 4. The number of columns 4 can be selected according to actual requirements, and three can be set with an adjacent included angle of 120°. The columns 4 are connected to a positioning mechanism for positioning the cylinder. The positioning mechanism includes multiple guide sleeves 11, multiple positioning rods 12, multiple springs 17, and multiple drive blocks 13. The guide sleeves 11 are connected to the outside of the columns 4. The positioning rods 12 are movably connected to the guide sleeves 11. The drive blocks 13 are connected to the ends of the positioning rods 12. The springs 17 are used to drive the positioning rods 12 to move closer to the drive blocks 13. The columns 4 are connected to a drive mechanism for driving the multiple drive blocks 13 to move forward synchronously. The spraying box 1 is connected to a spraying mechanism for synchronous spraying of multiple cylinders.

[0023] A single column 4 is equipped with nine positioning rods 12. The included angle between adjacent positioning rods 12 on the same horizontal plane is 120°. When the positioning rods 12 are pressed against the inner wall of the cylinder, the cylinder can be locked and fixed, and the cylinder can be kept in a vertical position to facilitate uniform subsequent spraying.

[0024] During the spraying operation, the three cylinders are placed on the corresponding columns 4. The drive mechanism drives the drive block 13 to move forward, which in turn drives the positioning rod 12 and guide block 18 to move forward. The spring 17 is gradually compressed until the end of the positioning rod 12 is pressed against the inner wall of the cylinder, which can achieve locking and fixation, improve the stability of the cylinder, facilitate subsequent spraying operations, and is applicable to the processing of shock absorber cylinders of different diameters. Each processing is carried out on the same batch of shock absorber cylinders, and the cylinder diameter of the batch is the same.

[0025] The positioning mechanism also includes multiple guide grooves 16 and multiple guide blocks 18. The guide blocks 18 are slidably connected to the guide grooves 16 and are fixedly connected to the positioning rod 12. The guide grooves 16 are set inside the guide sleeve 11. The guide blocks 18 can slide within the guide grooves 16, improving the stability of the reciprocating movement of the positioning rod 12 and achieving a good guiding purpose.

[0026] Spring 17 is located in guide groove 16, and both ends of spring 17 are connected to guide block 18 and guide sleeve 11.

[0027] The drive mechanism includes multiple pressing blocks 14, multiple lifting rods 15, an electric push rod 19, and a lifting frame 20. The pressing blocks 14 are matched with multiple drive blocks 13. The lifting rods 15 are fixedly connected to the pressing blocks 14 and slidably connected to the base 2, improving the stability of the lifting rods 15. This ensures that the multiple pressing blocks 14 move steadily and prevents misalignment between the pressing blocks 14 and the drive blocks 13. The lifting frame 20 is fixedly connected to the bottom of the multiple lifting rods 15. The electric push rod 19 is connected to the base 2, and its power output end is connected to the lifting frame 20. The electric push rod 19 drives the lifting frame 20 to move downward. The lifting frame 20 drives the three lifting rods 15 to move downward synchronously, thus moving the pressing blocks 14 downward. The pressing blocks 14 press against the drive blocks 13, causing them to slide relative to each other. This pushes the drive blocks 13 forward, thereby moving the guide block 18 and the positioning rod 12 forward, facilitating the positioning rod 12 to press and fix the cylinder. At this time, the spring 17 is in a compressed state. After the spraying is completed, the electric push rod 19 drives the lifting frame 20 to move upward, which in turn drives the three lifting rods 15 to move upward, so that the pressing block 14 moves upward. The pressing block 14 slides relative to the driving block 13, and the compressed spring 17 drives the guide block 18 to move backward, thereby realizing the positioning rod 12 moving backward. The end of the positioning rod 12 separates from the inner wall of the cylinder, thereby loosening the cylinder and facilitating unloading operations.

[0028] The axis of the lifting rod 15 coincides with the axis of the column 4.

[0029] The spraying mechanism includes a cylinder 5, a conveying hose 6, a hollow disc 7, multiple nozzles 8, multiple spray pipes 9, and a feeding device 10. The cylinder 5 drives the hollow disc 7 to rise and fall. The hollow disc 7 is connected to the multiple spray pipes 9. The nozzles 8 are connected to the inside of the spray pipes 9, which are located directly above the column 4. The end of the conveying hose 6 is connected to the hollow disc 7, and the output end of the feeding device 10 is connected to the conveying hose 6. After the cylinder is fixed, the cylinder 5 drives the hollow disc 7 to rise and fall, simultaneously driving the three spray pipes 9 to rise and fall, causing the spray pipes 9 to move along the height direction of the cylinder. At the same time, the feeding device 10 delivers paint through the conveying hose 6 into the hollow disc 7, then delivers it to the spray pipes 9, and finally sprays it out from the nozzles 8, making the cylinder sprayed evenly and efficiently, with strong practicality.

[0030] The feeding device 10 and the cylinder 5 are connected to the top of the spray box 1, and the feeding device 10 is located on one side of the cylinder 5. The power output end of the cylinder 5 is fixedly connected to the hollow disc 7.

[0031] The top of the hollow disc 7 is connected to a fixed interface, and the conveying hose 6 is detachably connected to the fixed interface. The conveying hose 6 has a corrugated structure, and the conveying hose 6 extends and retracts as the hollow disc 7 rises and falls.

[0032] The top of the base 2 is connected to multiple support plates 3, which are set at the bottom of the corresponding columns 4. When the cylinder is installed, the bottom of the cylinder is connected to the support plates 3 to support the cylinder.

[0033] The end of the positioning rod 12 is provided with a positioning head, which is made of rubber material. This increases the frictional force between the rod and the cylinder, while preventing wear on the inner wall of the cylinder.

[0034] Working Principle: The cylinder is fitted onto the corresponding column 4, with its bottom connected to the support plate 3. The electric push rod 19 drives the lifting frame 20 downwards, causing the three lifting rods 15 to move downwards as well. The pressing block 14 applies downward force to the driving block 13, driving it forward. The driving block 13 then moves the positioning rod 12 and guide block 18 forward, gradually compressing the spring 17. When the end of the positioning rod 12 presses against the inner wall of the cylinder, the cylinder is locked in place, improving its stability and facilitating subsequent spraying operations. Then, the cylinder 5 drives the hollow disc 7 to move, causing the three spray pipes 9 to reciprocate along the height of the cylinder, with the nozzles 8 facing the cylinder. The feeding device 10 delivers paint through the conveying hose 6 into the hollow disc 7, and then to the spray pipes 9, allowing the paint to be sprayed from the nozzles 8, achieving uniform spraying of the cylinder with high efficiency. After spraying is complete, the cylinder 5 drives the three spray pipes 9 to rise to a suitable height, providing space for cylinder disassembly. The electric push rod 19 drives the lifting frame 20 to move upward, which in turn drives the three lifting rods 15 to move upward. The pressing block 14 slides relative to the driving block 13, and the compressed spring 17 drives the guide block 18 to move backward, which in turn drives the positioning rod 12 to move backward, so that the end of the positioning rod 12 separates from the inner wall of the cylinder, thereby loosening the cylinder and facilitating unloading operations.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
