Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub spraying technology, and in particular to a device for easily adjusting the spraying of automotive wheel hub surfaces. Background Technology

[0002] A wheel hub is a cylindrical metal component inside a car tire, centered on an axle, used to support the tire. Simply put, it's the part in the center of the wheel where the axle is mounted. It's an important component connecting the brake drum, wheel disc, and half-shaft. During the manufacturing process, car wheel hubs typically require painting equipment to coat their surface, making them more aesthetically pleasing and extending their lifespan.

[0003] In the current technology, when painting car wheel rims, a certain amount of paint spraying fumes are generated and dispersed. These paint spraying fumes contain harmful components such as formaldehyde, which can cause poisoning symptoms when inhaled by the human body, affecting the health of workers. The dispersed fumes also adhere to surrounding parts and are difficult to deal with. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. In the prior art, when painting car wheel hubs, a certain amount of paint spraying gas is generated and dispersed. These paint spraying gases contain harmful components such as formaldehyde, which can cause poisoning symptoms when inhaled by the human body, affecting the health of workers. The dispersed gas also adheres to the surrounding parts and is difficult to deal with. Therefore, a car wheel hub surface spraying device that is easy to adjust is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable spraying device for automobile wheel hub surfaces includes a base and a cylinder. The cylinder is fixedly connected inside the base, and a piston disc is slidably connected inside the cylinder. A placement rod is rotatably connected to the piston disc, and the placement rod is slidably connected to the upper side wall of the base.

[0007] The base is equipped with protective components, including a protective plate, push rods, and an air supply pipe. A through groove is provided on the upper wall of the base, and the protective plate is slidably connected in the through groove. Two sleeves are fixedly connected in the base. One end of each of the two push rods is slidably connected in the sleeve, and the other end of each push rod is fixedly connected to the protective plate. The air supply pipe is fixedly connected between the cylinder and the sleeve.

[0008] Preferably, a U-shaped plate is fixedly connected to the upper surface of the base, and a rotating shaft is rotatably connected to the U-shaped plate. A torsion spring is provided between one end of the rotating shaft and the U-shaped plate, and the outer surface of the other end of the rotating shaft is provided with teeth. A mounting bracket is fixedly connected to the rotating shaft.

[0009] Preferably, the mounting bracket has an arc-shaped groove, a slide rod is slidably connected in the arc-shaped groove, and a spray nozzle is fixedly connected to the slide rod.

[0010] Preferably, a fixing plate is fixedly connected to the base, and springs are fixedly connected to both ends of the fixing plate.

[0011] Preferably, two rack plates are slidably connected to the base, the rack plates are engaged with the teeth on the rotating shaft, and the rack plates are fixedly connected to the end of the spring away from the fixed plate.

[0012] Preferably, the placement rod is provided with a protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Because the spray nozzle can slide in an arc-shaped trajectory on the mounting frame via the slide bar, connecting the spray nozzle to external spraying equipment, as the placement rod and the hub rotate, the spray nozzle can evenly apply the paint to the hub, while the scattered gas can be blocked by the protective plate, thus preventing the paint gas from spreading and affecting the surrounding equipment and personnel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0022] Reference Figures 1-4 A device for adjusting the surface coating of automobile wheel hubs includes a base 1 and a cylinder 13. The cylinder 13 is fixedly connected inside the base 1. A piston disc 12 is slidably connected inside the cylinder 13. A placement rod 3 is rotatably connected to the piston disc 12. The placement rod 3 is provided with a protrusion, so the wheel hub and the placement rod 3 can rotate. The placement rod 3 is slidably connected to the upper side wall of the base 1.

[0023] A protective component is installed on the base 1, including a protective plate 4, push rods 15, and an air supply pipe 14. A through groove is formed on the upper wall of the base 1, and the protective plate 4 is slidably connected within the groove. The protective plate 4 is not circular but has a notch. When the spray nozzle 11 slides on the mounting bracket 2, it is positioned on one side of the notch, allowing paint to be sprayed onto the hub through the notch. Two sleeves 16 are fixedly connected inside the base 1. One end of each push rod 15 is slidably connected within a sleeve 16, and the other end of each push rod 15 is fixedly connected to the protective plate 4. The air supply pipe 14 is fixedly connected between the cylinder 13 and the sleeves 16. As the gas inside the sleeves 16 increases, it pushes the push rods 15 upwards. 15 can push the protective plate 4 to move upward in the through groove and surround the hub. A U-shaped plate 6 is fixedly connected to the upper surface of the base 1. A rotating shaft 7 is rotatably connected to the U-shaped plate 6. A torsion spring is provided between one end of the rotating shaft 7 and the U-shaped plate 6. The outer surface of the other end of the rotating shaft 7 is provided with teeth. A mounting bracket 2 is fixedly connected to the rotating shaft 7. An arc-shaped groove is provided on the mounting bracket 2. A sliding rod 5 is slidably connected in the arc-shaped groove. A spray nozzle 11 is fixedly connected to the sliding rod 5. Since the spray nozzle 11 moves in an arc-shaped trajectory, the spray nozzle 11 can spray the paint in an L-shape when sliding, spraying it on one side and the upper side of the hub. As the hub rotates, the paint can be evenly sprayed on the outer surface of the hub.

[0024] A fixing plate 10 is fixedly connected to the base 1. Springs 9 are fixedly connected to both ends of the fixing plate 10. Two rack plates 8 are slidably connected to the base 1. The rack plates 8 are engaged with the teeth on the rotating shaft 7. The rack plates 8 are fixedly connected to the end of the springs 9 away from the fixing plate 10.

[0025] In this utility model, when in use, the mounting bracket 2 is first pushed, and the mounting bracket 2 rotates 90 degrees around the pivot 7. When rotating, it can cause the torsion spring to deform. At the same time, when the pivot 7 rotates, it can cause the meshing rack plate 8 to move towards the square of the fixed plate 10 and compress the spring 9.

[0026] Then, the painted car wheel hub is placed on the placement rod 3. At this time, the placement rod 3 is in the central circular hole of the car wheel hub and on the upper side of the protrusion. When the placement rod 3 is subjected to the weight of the car wheel hub, it moves downward and pushes the piston disc 12 to move down in the cylinder 13. It also compresses the gas in the cylinder 13 and sends it through the gas pipe 14 into the two sleeves 16. As the gas in the sleeves 16 increases, it can push the push rod 15 to move upward. When the push rod 15 moves upward, it can push the protective plate 4 to move to one side of the car wheel hub. The mounting bracket 2 is released, and the rack plate 8 moves to the right and resets under the push of the spring 9. It can drive the rotating shaft 7 to rotate counterclockwise. At the same time, under the drive of the torsion spring, it can also drive the mounting bracket. 2. Reset and rotate: Since the spray nozzle 11 can slide on the mounting frame 2 in an arc-shaped motion trajectory through the slide rod 5, the spray nozzle 11 is connected to the external spraying equipment. With the rotation of the placement rod 3 and the hub, the spray nozzle 11 can evenly apply the paint to the hub, and the scattered gas can be blocked by the protective plate 4, thus preventing the paint gas from spreading and affecting the surrounding equipment and personnel. After the hub is sprayed, it no longer exerts downward pressure on the placement rod 3. The protective plate 4 moves down under its own weight and pushes the gas in the sleeve 16 through the gas pipe 14 back to the cylinder 13 through the push rod 15, and pushes the placement rod 3 up and reset, in preparation for subsequent hub spraying processing.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
