Description

Technical Field

[0001] This invention relates to the field of automotive painting tools, and more particularly to an automotive painting conveying fixture and method of use for adaptive vehicle models. Background Technology

[0002] Automotive painting is a crucial step in automobile manufacturing. Through a multi-layer coating process, a composite coating is formed on the vehicle body surface, providing anti-corrosion, decorative, and special identification functions. It plays a key role in enhancing the vehicle's lifespan, aesthetics, and commercial value. Automotive coatings can isolate moisture, microorganisms, and ultraviolet radiation, preventing steel corrosion and extending the vehicle's lifespan. The development from solid colors to metallic and pearl paints allows for a visually appealing effect, satisfying individual aesthetic demands. The choice of painting processes and materials directly affects the added value of a vehicle. Furthermore, specific body colors can distinguish the vehicle's purpose, such as the bright red of fire trucks and the olive green of postal vehicles, facilitating rapid identification and emergency response.

[0003] Many automotive components require painting, typically using electrophoretic coating. The principle of electrophoretic coating is based on the electrophoresis phenomenon in electrochemistry. Under the influence of an electric field, positively or negatively charged paint particles move towards the electrode with the opposite charge and deposit on the electrode surface to form a coating. In a Chinese utility model patent titled "Jig for Electrophoretic Coating of Automotive Components" (publication number CN222821688U), the automotive components to be electrophoresed are placed in an upper and lower clamping assembly. The lower wall of the automotive component contacts the lower part of the clamping rod on the lower clamping assembly, thus clamping the component. Simultaneously, the clamping rod on the upper clamping assembly opens outwards under gravity, pressing against the inner wall of the automotive component, thereby fixing the component inside the fixture body. However, in this application, the clamping rod position is fixed. This makes it difficult to fix different components that make up the vehicle, resulting in a limited applicability of the fixture. This necessitates changing different fixtures during painting, affecting the processing efficiency of automotive painting. Summary of the Invention

[0040] Figures 1 to 12 The diagram shown is a structural schematic of an embodiment of the adaptive vehicle model automotive painting conveying fixture and its usage method of the present invention.

[0041] The adaptive vehicle painting conveying fixture includes a conveying support frame 1 and a clamping unit. The upper part of the clamping unit is driven to a height control unit. Both ends of the height control unit are driven to a rotating unit. Both ends of the rotating unit are driven to a conveying unit. The conveying unit is located on the top of the conveying support frame 1. The clamping unit includes a fixed frame 2. Two symmetrically distributed mounting components 3 are arranged below the fixed frame 2. Both mounting components 3 are connected to the inner side of the fixed frame 2 via a control component 4. An adaptation component 6 is arranged on one side of the mounting component 3. The adaptation component 6 is connected to the mounting component 3 via a displacement component 5. The displacement component 5 is located at the mounting component 3. Multiple clamping plates 7 arranged in a circular array are connected to one side of the adaptation component 6. The clamping plates 7 on both sides clamp the automotive parts.

[0042] In this technical solution, the positions of the two side adaptation components 6 and clamping plates 7 can be adjusted by the displacement component 5. At the same time, the positions of multiple clamping plates 7 can be adjusted synchronously by the adaptation component 6, so that the clamping plates 7 can adapt to different models of automotive parts, making the fixture adaptable to different vehicle models, expanding the applicability of the fixture, eliminating the need to change the fixture when changing the model of automotive parts, and improving the efficiency of automotive painting.

[0043] In use, the position of the two side adaptation components 6 is adjusted by the displacement component 5 according to the shape and size of the automotive parts. Then, the position of multiple clamping plates 7 is adjusted by the adaptation component 6 so that the clamping plates 7 can adapt to different models of automotive parts. The automotive parts are positioned between the two side clamping plates 7, maintaining a neutral position. Then, the control component 4 drives the two side displacement components 5, adaptation components 6 and clamping plates 7 to move towards each other, so that the two side clamping plates 7 clamp and fix the automotive parts. The moving component 14 drives the upper frame 8, mounting component 3 and clamping plates 7 to move in the same direction to complete the transportation of the automotive parts and move the automotive parts into the electrophoretic coating tank. The control component 4 drives the displacement component 5, adaptation component 6 and clamping plates 7 to move downward, thereby moving the automotive parts downward and immersing the automotive parts in the electrophoretic coating tank for electrophoretic coating. The first frame 11, second frame 12 and rotational power source 13 drive the upper frame 8 and clamping plates 7 to flip, thereby flipping the automotive parts and performing full electrophoretic coating on the automotive parts.

[0044] The control component 4 includes a control power source 41, which is connected to the inside of the fixed frame 2. The output end of the control power source 41 is connected to a control bidirectional threaded column 42. The control bidirectional threaded post 42 has two symmetrically distributed movable plates 43 connected to its surface by threads. The bottoms of the two movable plates 43 are respectively connected to the tops of the two mounting components 3.

[0045] The inner side of the fixed frame 2 is connected to a plurality of fixed rails 44, and the surface of the fixed rails 44 is slidably connected to the movable plate 43.

[0046] In use, the movable plate 43 moves along the fixed track 44, and the fixed track 44 limits the movement trajectory of the movable plate 43.

[0047] The control power source 41 is connected inside the protective housing.

[0048] In this technical solution, the control component 4 can control the movement of the adaptation components 6 and clamping plates 7 on both sides towards or away from each other, thereby controlling the clamping and releasing of the fixture.

[0049] In use, the control power source 41 drives the control bidirectional threaded column 42 to rotate, thereby driving the moving plates 43 on both sides to move towards or away from each other along the fixed track 44, which in turn drives the mounting component 3, displacement component 5, adaptation component 6 and clamping plate 7 to move in the same direction, so that the clamping plates 7 on both sides can be clamped or released.

[0050] The mounting component 3 includes a mounting frame 31 and a reinforcing frame 32. The reinforcing frame 32 is connected to the mounting frame 31 on both the upper and lower sides. The mounting frames 31 on both sides are connected to the mounting housing 33 at both ends. The mounting component 3 is provided with a displacement component 5.

[0051] In this technical solution, the displacement component 5 and the adaptation component 6 can be supported by the mounting component 3.

[0052] The displacement component 5 includes a displacement power source 51, which is connected to the inner wall of the mounting housing 33. The output end of the displacement power source 51 is connected to a central gear 52. Both the upper and lower sides of the central gear 52 are meshed with transmission gears 53. The side of the transmission gears 53 is meshed with a side gear 54. Both of the mounting frames 31 are provided with a displacement bidirectional threaded shaft 55 on their inner sides. The two ends of the displacement bidirectional threaded shaft 55 are rotatably connected to the side of the mounting frame 31 and the side of the mounting housing 33, respectively, and both ends of the displacement bidirectional threaded shaft 55 are connected with a side gear 54.

[0053] The inner wall of the mounting housing 33 is connected to a plurality of anti-deviation rails 58, and the surface of the anti-deviation rails 58 is slidably connected to the displacement plate 56.

[0054] When the displacement plate 56 moves, it moves along the anti-deviation track 58, and the anti-deviation track 58 limits the movement trajectory of the displacement plate 56.

[0055] In this technical solution, the position of the adaptation component 6 is adjusted by the displacement component 5.

[0056] In use, the displacement power source 51 drives the middle gear 52 to rotate, which in turn drives the transmission gear 53 to rotate, which in turn drives the side gear 54 to rotate. When the side gear 54 rotates, it drives the displacement bidirectional threaded shaft 55 to rotate. When the displacement bidirectional threaded shaft 55 rotates, it drives the displacement plates 56 on both sides to move towards or away from each other along the anti-deviation track 58, which in turn drives the corresponding adaptation component 6 and clamping plate 7 to move in the same direction, thereby adjusting the position of the adaptation component 6 and clamping plate 7.

[0057] Both of the mounting housings 33 have a central gear 52 in their inner cavities. The two central gears 52 on both sides are connected to the two ends of the drive shaft 57 respectively. The surface of the drive shaft 57 is rotatably connected to the reinforcing frame 32 and the side of the mounting housing 33.

[0058] In this technical solution, the transmission shaft 57 can be used to synchronously connect the intermediate gears 52 on both sides.

[0059] The adaptation component 6 includes an adaptation housing 61, one side of which is connected to one side of the displacement plate 56; An adaptive power source 62 is installed in the inner cavity of the adaptive housing 61.

[0061] The eccentric plate 66 is composed of two structures: a plate-like structure and an I-shaped cross-section, with the two structures arranged alternately.

[0062] In this technical solution, the positions of multiple clamping plates 7 can be adjusted simultaneously by the adaptation component 6.

[0063] In use, depending on the model of the automotive parts, the adaptive power source 62 drives the drive gear 63 to rotate, thereby driving multiple driven gears 64 to rotate, which in turn drives the corresponding connecting shaft 65 to rotate, thereby driving the eccentric plate 66 to rotate. When the eccentric plate 66 rotates, it drives the corresponding clamping plate 7 to rotate, thereby adjusting the clamping end position of the clamping plate 7.

[0064] The height control unit includes an upper frame 8 and a lower frame 9, which are connected by a lifting assembly 10. The lifting assembly 10 includes a protective housing 101, which is connected to the inner wall of the upper frame 8. A telescopic device 102 is installed inside the protective housing 101, and the two output ends of the telescopic device 102 extend to the outside of the protective housing 101 respectively. Both output ends of the telescopic device 102 are connected to the active plate 103. A driven plate 104 is provided below the active plate 103.

[0065] In this technical solution, the height of the adaptive component 6 and the clamping plate 7 can be adjusted by the lifting component 10 so that the automotive parts can be immersed in the electrophoretic coating liquid.

[0066] In use, the telescopic device 102 drives the active plates 103 on both sides to move towards or away from each other along the upper fixed column 108. At this time, under the action of the rotating connecting seat 107, the cross movable frame 106 can rotate, thereby driving the corresponding driven plate 104 to move along the lower fixed column 105. When the cross movable frame 106 rotates, it causes the lower frame 9, fixed frame 2 and clamping plate 7 and other structures to move up and down to complete the electrophoretic coating of automotive parts.

One end of the rotary power source 13 is connected to one side of the upper frame 8, and the other side of the upper frame 8 is rotatably connected to one side of the second frame 12.

[0071] In this technical solution, the rotating unit can be used to flip the automotive parts, so that the automotive parts can fully contact the electrophoretic coating liquid.

[0072] In use, the rotating power source 13 can drive the upper frame 8 to rotate, thereby driving the lifting assembly 10, the mounting component 3 and the clamping plate 7 to rotate, and thus flipping the automotive parts.

[0073] The conveying unit includes a moving component 14, which includes a walking plate 141. The walking plate 141 is connected to the opposite side of the first frame 11 and the second frame 12.

[0074] The side of the conveying support frame 1 is connected to a protective cover 15, which is located outside the moving gear 144 and the fixed rack 145.

[0075] In this technical solution, the clamping plate 7 and automotive parts can be moved by the conveying unit, so that the automotive parts can be conveyed and moved between multiple operation processes such as electrophoretic coating.

[0076] In use, the mobile power source 143 drives the mobile gear 144 to rotate. At this time, under the action of the fixed rack 145, the walking plate 141 can be driven to move in the same direction along the anti-detachment track 142, thereby driving the upper frame 8 and clamping plate 7 and other structures to move in the same direction, thereby driving the movement of automobile parts and conveying the automobile parts.
