Description

Technical Field

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

[0002] Automotive aftermarket painting is an important part of the automotive aftermarket, encompassing areas such as personalization, restoration and refurbishment, racing modifications and commercial vehicle painting. With the surge in consumer demand for unique appearances such as matte, pearlescent, metallic, chameleon paint and custom patterns, painting technology and equipment are constantly being upgraded, driving the industry toward high-precision spraying while meeting stringent environmental regulations and the need for efficient small-batch production.

[0003] In automotive painting operations, traditional spraying equipment suffers from the significant drawback of inconvenient spray head angle adjustment, severely restricting painting efficiency and quality. Currently widely used manual spray guns or stationary automatic spraying machines typically employ a rigid connection structure, resulting in an extremely limited adjustable angle range for their spray heads. This makes it easy to create blind spots or uneven coating thickness when spraying complex curved surfaces such as wide-body wheel arches, spoilers, and hood edges.

[0004] In response to this technical problem, this application proposes a painting device for automobile modification. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a painting device for automotive modification. This device ensures all-around coverage during spraying and is particularly suitable for irregularly shaped modification parts such as wheel hubs and body kits. It significantly improves the uniformity and efficiency of spraying, expands the spraying coverage area, and is especially suitable for complex curved surfaces such as wheel arches and spoilers. It ensures a uniform coating without dead corners and improves the spraying effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A painting device for automotive modification includes a fixed housing, a liquid tank fixedly connected to the top of the fixed housing, a connecting platform fixedly connected to the outer wall of the fixed housing, a motor fixedly connected to both the left and right ends of the inner wall of the connecting platform, a spray head connected to the drive end of the motor via a spray assembly, a clamping platform fixedly connected to the bottom end of the inner wall of the fixed housing, an electro-hydraulic rod fixedly connected to the left end of the inner wall of the clamping platform, a second motor fixedly connected to the right end of the inner wall of the clamping platform, and a clamping claw connected to the drive end of the electro-hydraulic rod via a fixed assembly.

[0008] Furthermore, the spraying assembly includes deflector plates fixedly connected to one drive end of the motor, and adapter blocks rotatably connected to one end of each deflector plate.

[0009] Furthermore, rotating rods are rotatably connected to both ends of the fixed shell, and rotating frames are fixedly connected to the outer walls of the rotating rods. The opposite end of the adapter block is sleeved on the outer wall of the opposite end of the rotating frame, and the opposite end of the rotating frame is fixedly connected to the opposite end of the spray head.

[0010] Furthermore, a water pump is installed on the inner wall of the liquid tank, and a three-way pipe is fixedly connected to the drive end of the water pump. Both ends of the three-way pipe are fixedly connected to delivery pipes, and the other end of the delivery pipe is fixedly connected to the outer wall of the top of the spray head. An inlet is fixedly connected to the top of the liquid tank.

[0011] Furthermore, the fixing assembly includes a transition plate rotatably connected to the drive end of the electro-hydraulic rod, and traction plates are rotatably connected to all four sides of the outer wall of the transition plate.

[0012] Furthermore, a driven gear is fixedly connected to the bottom end of the adapter plate, and a driving gear is fixedly connected to the second drive end of the motor. The driven gear and the driving gear are meshed together.

[0013] Furthermore, a rotating plate is rotatably connected to the top of the clamping platform, and clamping claws are rotatably connected to all four sides of the outer wall of the rotating plate. The opposite ends of the traction plate are rotatably connected to the opposite ends of the clamping claws.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when the workpiece is placed on the rotating plate, the electric hydraulic rod pushes the adapter plate to drive the clamping claw to clamp the workpiece. At the same time, the second motor drives the rotating plate to rotate through the driving gear and the driven gear. This structure realizes automatic clamping and stepless rotation of the workpiece, ensuring all-round coverage during spraying. It is especially suitable for irregularly shaped modified parts such as wheel hubs and body kits, and significantly improves the uniformity and efficiency of spraying.

[0016] 2. In this utility model, the water pump is started to divert the paint in the liquid tank to the delivery pipe through the three-way pipe and supply it to the spray head for spraying. At the same time, the motor drives the deflection plate, which drives the rotating frame to deflect through the adapter block, so that the spray head can automatically swing. This design significantly expands the spraying coverage area and is especially suitable for complex curved surfaces such as wheel arches and spoilers, ensuring that the coating is uniform and without dead corners, and improving the spraying effect.

[0023] 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.

[0024] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a painting device for automotive modification, comprising a fixed housing 1, a liquid tank 3 fixedly connected to the top of the fixed housing 1, a connecting platform 2 fixedly connected to the outer wall of the fixed housing 1, and motors 11 fixedly connected to both ends of the inner wall of the connecting platform 2. The driving ends of the motors 11 are connected to spray heads 7 via spraying units. The spraying units include deflector plates 12 fixedly connected to the driving ends of the motors 11, and adapter blocks 13 rotatably connected to opposite ends of the deflector plates 12. The fixed housing 1 has a fixed housing 1 at both ends. All are rotatably connected to a rotating rod 22, and a rotating frame 14 is fixedly connected to the outer wall of the rotating rod 22. The opposite end of the adapter block 13 is sleeved on the outer wall of the opposite end of the rotating frame 14. The opposite end of the rotating frame 14 is fixedly connected to the opposite end of the spray head 7. A water pump 15 is installed on the inner wall of the liquid tank 3. A three-way pipe 16 is fixedly connected to the drive end of the water pump 15. Both ends of the three-way pipe 16 are fixedly connected to a delivery pipe 6. The other end of the delivery pipe 6 is fixedly connected to the top outer wall of the spray head 7. A dispensing port 4 is fixedly connected to the top of the liquid tank 3.

[0025] Specifically: In the operation of the painting equipment for automotive modification, the water pump 15 is first started to pressurize and deliver the special paint stored in the liquid tank 3 to the three-way pipe 16. Through the diversion effect of the three-way pipe 16, the paint is evenly distributed to the two sets of delivery pipes 6, and then continuously supplied to the symmetrically arranged spray heads 7, ensuring that the two spray heads synchronously perform high-precision atomized spraying on the surface of the workpiece. At the same time, the motor 11 is started to drive the eccentric wheel type deflector plate 12 to rotate around the axis. The deflector plate 12 forms a crank-slider machine with the rotating frame 14 through the hinged connecting block 13. Under the limiting and guiding action of the rotating rod 22, the rotating frame 14 is forced to periodically reciprocate along a preset trajectory. This linkage mechanism converts the rotational motion of the motor into the fan-shaped oscillation of the spray head 7 (amplitude adjustable range ±45°), dynamically expanding the spray coverage area. It is especially suitable for spraying complex curved surfaces such as wide-body wheel arches and aerodynamic kits in automobile modification without dead angles, effectively eliminating the coating accumulation or missed spray defects caused by the limited angle of traditional fixed spray guns, and significantly improving the surface coating uniformity and paint film adhesion of irregular workpieces.

[0026] Reference Figure 2 and Figure 4 A clamping platform 5 is fixedly connected to the bottom of the inner wall of the fixed shell 1. An electric hydraulic rod 17 is fixedly connected to the left end of the inner wall of the clamping platform 5. A motor 18 is fixedly connected to the right end of the inner wall of the clamping platform 5. The driving end of the electric hydraulic rod 17 is connected to a clamping claw 9 through a fixed assembly. The fixed assembly includes a transition plate 21 rotatably connected to the driving end of the electric hydraulic rod 17. Traction plates 10 are rotatably connected to all four sides of the outer wall of the transition plate 21. A driven gear 20 is fixedly connected to the bottom of the transition plate 21. A driving gear 19 is fixedly connected to the driving end of the motor 18. The driven gear 20 and the driving gear 19 are meshed. A rotating plate 8 is rotatably connected to the top of the clamping platform 5. Clamping claws 9 are rotatably connected to all four sides of the outer wall of the rotating plate 8. The opposite ends of the traction plates 10 are rotatably connected to the opposite ends of the clamping claws 9.

[0027] Specifically, in the workpiece positioning system of the automotive painting device, after the workpiece to be painted is placed on the rotating plate 8 equipped with ball bearings, the double-stroke electro-hydraulic rod 17 is activated to push the adapter plate 21 to move along the guide rail. Through the wedge-shaped sliding groove mechanism between the adapter plate 21 and the traction plate 10, the linear motion is converted into rotational torque, driving the symmetrically distributed clamping claws 9 to synchronously close within the arc-shaped slots of the rotating plate 8. The silicone buffer pads at the claw ends adaptively clamp workpieces with different curved surfaces, ensuring rigid fixation without damaging the paint surface. Subsequently, the servo motor 18 is activated to drive the nitrided active gear 19 to rotate. Through a 1:2 reduction transmission with the driven gear 20, the adapter plate 21 and the traction plate 10 form a planetary gear system, driving the rotating plate 8 to rotate at a continuously variable speed of 0-30 r / min. This composite motion mechanism enables the workpiece to rotate continuously 360° during the spraying process. Combined with the swing trajectory of the spray head 7, it can completely cover the surfaces of multi-faceted modified parts such as air intake grilles and diffusers, avoiding coating seam problems caused by manual flipping, and significantly improving the coating efficiency and film thickness uniformity of complex curved workpieces.

[0028] Working principle: When the workpiece to be painted is placed on the rotating plate 8, the electric hydraulic rod 17 is activated to drive the adapter plate 21, which in turn pulls the traction plate 10, causing the clamping jaws 9 to rotate on the rotating plate 8. This clamping jaws 9 clamp and fix the workpiece. Meanwhile, the rotating motor 18 drives the drive gear 19 to rotate, which in turn drives the driven gear 20. With the cooperation of the traction plate 10, the adapter plate 21 causes the rotating plate 8 to rotate, allowing the workpiece to rotate while being clamped. To facilitate the display of the workpiece surface, the water pump 15 is started to pour the paint in the liquid tank 3 into the three-way pipe 16, and the delivery pipe 6 pours the paint into the spray head 7, so that the spray head 7 can spray paint on the workpiece. The motor 11 is started to drive the deflection plate 12 to rotate, so that the deflection plate 12 pulls the rotating frame 14 to move through the adapter block 13, so that the rotating frame 14 deflects under the action of the rotating rod 22, so that the spray head 7 swings, speeding up the spraying surface of the spray head 7 and increasing the coverage of the workpiece.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
