Description

Technical Field

[0001] This utility model belongs to the field of automotive door panel processing technology, and in particular to an automotive FRP door panel spraying tool. Background Technology

[0002] FRP (fiber reinforced plastic) door panels are automotive door interior / exterior panel components made of fiber reinforced plastic. They are lightweight, high-performance composite automotive parts.

[0003] In the field of automotive FRP door panel painting, the appropriate choice of tooling fixing method directly affects the painting quality and production efficiency. Currently, the industry commonly uses positioning hole fixing technology, which utilizes pre-fabricated assembly holes on the door panel body in conjunction with tapered positioning pins to fix the workpiece. In practice, operators need to press the door panel through the process holes distributed along its edges against the tapered positioning pins on the tooling platform to form an interference fit, thus creating a mechanical lock.

[0004] However, this fixing method has significant drawbacks in practical applications: additional processing burden: because the assembly holes of automotive door panels during the final assembly stage often do not match the positioning requirements of the painting tooling, manufacturers have to perform secondary processing on the FRP door panels to create dedicated positioning holes. Industry data shows that this requires several additional drilling processes per door panel, significantly increasing labor and equipment costs. Therefore, developing a non-invasive fixing tooling that does not damage the door panel structure and is adaptable to multiple vehicle models has become a pressing technical challenge in this field.

[0005] The purpose of this utility model is to provide a spraying fixture for automotive FRP door panels to solve the problems mentioned in the background art. Utility Model Content

[0020] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0021] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0022] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0023] Please see Figures 1 to 3 As shown, an automotive FRP door panel spraying fixture is characterized by including a workbench 1 and a spraying mechanism 3. The spraying mechanism 3 is existing technology, and its working principle will not be described in detail here. It is located on the top of the workbench 1.

[0024] The workbench 1 is equipped with a fixing assembly 2 for fixing the FRP door panel of the car. The fixing assembly 2 includes a motor 28 fixedly installed at the bottom of the workbench 1. The output end of the motor 28 is provided with a drive gear 27. The drive gear 27 is symmetrically provided with racks 25 on both sides, and the racks 25 are meshed with the drive gear 27. Each rack 25 is symmetrically provided with limit plates 26 on its upper and lower sides. The limit plates 26 are used to limit the movement trajectory of the racks 25. The limit plates 26 and the top of the workbench 1 are both provided with sliding grooves 5. Each rack 25 is provided with a connecting post 24 on its top. The connecting post 24 is slidably connected in the sliding groove 5. The top of the connecting post 24 is provided with a mounting plate 21. A connecting plate 22 is provided on one side of the mounting plate 21. A support plate 23 is inserted into the bottom of the connecting plate 22. The support plate 23 is used to support the FRP door panel of the car. After fixing it, the support plate 23 can be removed so that the FRP door panel of the car can be flipped over for spraying.

[0025] A limiting mechanism is located on one side of the fixed component 2. This limiting mechanism is used to limit the tilted FRP door panel of the car. The limiting component 4 includes a sliding post 42, which is located on one side of one of the mounting plates 21. One end of the sliding post 42 is fitted with a mounting plate 41, and a spring 43 is sleeved on the outside of the sliding post 42. One end of the spring 43 is connected to the mounting plate 41, and the other end is connected to the mounting plate 21. The other end of the sliding post 42 is fitted with a retaining plate 48, which consists of two rectangular plates. A first bevel gear 44 is located at the bottom of each mounting plate 21. The gear 44 is meshed with the second bevel gear 45. A mounting post 47 is provided at the back axis of the second bevel gear 45. The mounting post 47 passes through the mounting plate 21 and is connected to the rotating disk 46 at its end. The rotating disk 46 is located on the back of the connecting plate 22. Under normal conditions, the clamping plate 48 at the bottom of the sliding post 42 is clamped on a certain tooth block of the first bevel gear 44, restricting its rotation. This limits the fixing component that fixes the flipped FRP door panel, preventing it from rotating, thereby ensuring the stability of the FRP door panel and facilitating the normal operation of the painting work.

[0026] The motor 28 and the spraying mechanism 3 are both existing technologies. Their working principles, dimensions and models are not related to the problems solved by this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0027] Working principle: The FRP door panel of the car is placed on the support plate 23. Then, the motor 28 in the workbench 1 is started. The motor 28 drives the drive gear 27 to rotate, thereby driving the two racks 25 meshing with it to move. The racks 25 slide within the limiting plate 26, which in turn drives the sliding groove 5 to slide. This causes the connecting column 24 to move the mounting plate 21, which in turn moves the connecting plate 22, thus fixing the FRP door panel of the car. Then, the support plate 23 is removed, and the spraying mechanism 3 starts working. After this side is sprayed, the mounting plate 23 is pulled outward. The mounting plate 41 is installed, which in turn drives the sliding column 42 to slide, thereby stretching the spring 43. As a result, the clamping plate 48 no longer limits the first bevel gear 44. Then, the connecting plate 22 is rotated, which drives the rotating plate 46 to rotate, thereby driving the mounting column 47 to rotate. Then, the second bevel gear 45 at the end of the mounting column 47 drives the first bevel gear 44 that meshes with it, thereby flipping the FRP door panel of the car. After flipping to the correct position, the mounting plate 41 is released, the spring 43 returns to its original deformation, and the clamping plate 48 can then limit the first bevel gear 44 to prevent it from continuing to rotate.
