Technical Field
[0001] This utility model application relates to the field of automotive trim panel painting technology, and in particular to a fixed fixture for automotive trim panel painting. Background Technology
[0002] In the automotive manufacturing and repair industry, the painting process for automotive trim panels is a crucial step in shaping the vehicle's aesthetic appearance and enhancing its quality. High-quality paint not only gives the trim panels vibrant colors and a unique luster but also forms a protective barrier, effectively resisting external environmental damage such as UV radiation, rain, and minor scratches, thus significantly improving the trim panels' durability and lifespan. With the booming development of the automotive industry and consumers' ever-increasing demands for vehicle quality, the precision, efficiency, and quality control of automotive trim panel painting processes are receiving increasing attention.
[0003] Regarding the aforementioned technologies, the inventors believe that some tooling uses a fixed structural design, which makes it difficult to adapt to automotive trim panels of different models, sizes, and shapes. During the fixing process, uneven force or excessive contact area can easily cause damage such as indentations and scratches on the trim panel surface, affecting the appearance and quality of the trim panel. At the same time, some tooling lacks flexible angle adjustment functions, making it difficult to spray all parts of the trim panel comprehensively and evenly during the painting process, easily creating spraying dead corners, resulting in uneven paint thickness and inconsistent color, reducing the quality and efficiency of painting. Therefore, a fixed tooling for painting automotive trim panels is proposed to solve the above problems.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0005] To address the aforementioned problems, this application provides a fixture for painting automotive trim panels.
[0006] The present utility model application provides a fixing fixture for painting automotive trim panels, which adopts the following technical solution:
[0007] A fixture for painting automotive trim panels includes a movable base. Supports are fixedly connected to both outer walls of the movable base, and a rotating frame is disposed between the supports. The rotating frame is rotatably connected to the two supports. Multiple adjusting seats are slidably connected to the outer wall of the rotating frame. Square grooves are formed on both outer walls of each adjusting seat, and adjusting rods are slidably mounted on the adjusting seats through these square grooves. Arc-shaped straight grooves are formed on the outer walls of the adjusting rods, and vacuum suction cups are mounted on the adjusting rods through these arc-shaped straight grooves. A rotating assembly is provided on the side outer wall of the support.
[0008] Preferably, the adjusting seat is threadedly connected to a fixed threaded rod, and the outer wall of the fixed threaded rod is rotatably connected to a fixing pad.
[0009] Preferably, the rotating assembly includes a rotating gear, which is rotatably connected to the outer side wall of the bracket, and the rotating gear is rotatably connected to the bracket and the rotating frame. A rotating handle is fixedly connected to the outer side wall of the rotating gear, and a locking structure is provided on the outer wall of the bracket below the rotating handle.
[0010] Preferably, the engaging structure includes two external brackets, and the two external brackets are fixedly connected to the outer side wall of the support. The two external brackets are slidably connected to a brake block, which is adapted to a rotating gear. A control block is fixedly connected to the outer wall between the two external brackets, and a spring is provided between the control block and the external bracket.

[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. This device, through its multi-stage adjustment structure consisting of an adjustment seat, an adjustment rod, and a vacuum suction cup, allows the adjustment seat to slide on the rotating frame while the adjustment rod moves and adjusts on the groove above the adjustment seat. This enables flexible adjustment of the vacuum suction cup's position, allowing for precise adaptation to various sizes and shapes of automotive trim panels. Furthermore, the use of vacuum adsorption results in a small contact area and uniform force distribution, effectively preventing damage to the trim panel surface caused by improper fixing. This provides comprehensive protection for the trim panel's quality and expands the applicability of the tooling.

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.
[0021] A fixed fixture for painting automotive trim panels includes a movable base 1. Supports 2 are fixedly connected to both outer walls of the movable base 1, and a rotating frame 3 is disposed between the supports 2. The rotating frame 3 is rotatably connected to the two supports 2, and its two ends are rotatably connected to the two supports 2 via bearings, allowing the rotating frame 3 to rotate flexibly between the supports 2. The design of the rotating frame 3 provides the possibility for multi-angle adjustment of the fixture during the painting process of automotive trim panels, laying the foundation for the coordinated operation of subsequent components. Multiple adjusting seats 13 are slidably connected to the outer wall of the rotating frame 3. By adjusting the multiple adjusting seats 13, the position of the subsequent vacuum suction cup 6 can be adjusted, thereby facilitating the vacuum suction cup 6 to adsorb automotive trim panels such as car doors, facilitating subsequent painting. Square grooves 17 are provided on both outer walls of the bracket 2, and an adjusting rod 4 is slidably installed on the adjusting seat 13 through the square grooves 17. The adjusting rod 4 slides in the square grooves 17 to further adjust the position of the vacuum suction cup 6 to adapt to different sizes of car trim panels. The outer wall of the adjusting rod 4 is provided with an arc-shaped straight groove 18. The vacuum suction cup 6 is installed on the adjusting rod 4 by sliding in the arc-shaped straight groove 18 and fixing it with bolts. The adjusting rod 4 is installed with the vacuum suction cup 6 through the arc-shaped straight groove 18. The position of the vacuum suction cup 6 is adjusted according to the shape of the car trim panel and the adsorption requirements. The various components cooperate with each other to flexibly and accurately fix car trim panels of different sizes and shapes, providing a strong guarantee for the smooth progress of subsequent painting operations. The outer wall of the bracket 2 is provided with a rotating component.
[0022] The adjusting seat 13 is threadedly connected to a fixed threaded rod 16, and a fixed pad 15 is rotatably connected to the outer wall of the fixed threaded rod 16. First, the adjusting seat 13 is slidably adjusted on the rotating frame 3. After the adjustment is made to a suitable position, the fixed threaded rod 16 is rotated to move the fixed pad 15, so that it fits against the rotating frame 3, thereby fixing the adjusting seat 13.
[0023] The rotating assembly includes a rotating gear 7, which is rotatably connected to the outer side wall of the bracket 2. The rotating gear 7 rotates through the bracket 2 and is fixedly connected to the rotating frame 3. A rotating handle 8 is fixedly connected to the outer side wall of the rotating gear 7. When it is necessary to adjust the angle of the rotating frame 3, the operator rotates the rotating gear 7 through the rotating handle 8. The rotating gear 7 is connected to the rotating frame 3 by a key, thereby driving the rotating frame 3 to rotate, thereby adjusting the angle of the fixed car trim panel to facilitate the operator's painting. The outer wall of the bracket 2 located below the rotating handle 8 is provided with a locking structure, which can fix the adjusted angle of the rotating frame 3.
[0024] The engaging structure includes two external brackets 10, which are fixedly connected to the outer side wall of the support 2. The two external brackets 10 are slidably connected to a brake block 9, which is adapted to the rotating gear 7. A control block 11 is fixedly connected to the outer wall of the brake block 9 between the two external brackets 10. A spring 12 is provided between the control block 11 and the external brackets 10. The two ends of the spring 12 are fixedly connected to the control block 11 and the external brackets 10, respectively. When the angle of the rotating frame 3 needs to be adjusted, the control block 11 is pulled down, which causes the brake block 9 to move down, thereby disengaging it from the tooth groove of the rotating gear 7, thus facilitating the rotation of the rotating gear 7. After the rotation is completed, the control block 11 is released, and under the action of the spring 12, the brake block 9 rebounds, meshing with the tooth groove of the rotating gear 7 and fixing the rotating gear 7.
[0025] The outer wall of the vacuum suction cup 6 is fixedly connected to an adjusting threaded rod 5. The outer wall of the adjusting threaded rod 5 is threaded with two nuts. By tightening the two nuts, the vacuum suction cup 6 can be fixed at different positions on the adjusting rod 4. The outer wall of the adjusting threaded rod 5 is provided with an air inlet, which is connected to the inside of the vacuum suction cup 6. A vacuum pump is set externally, and the opening and closing of the air inlet is controlled to control the adsorption and release of the vacuum suction cup 6.
[0026] The implementation principle of a fixing fixture for painting automotive trim panels according to an embodiment of this utility model is as follows: The fixing fixture for painting automotive trim panels uses a movable base 1 as the basic support structure. The brackets 2 welded on both sides provide fulcrums for the rotation connection of the rotating frame 3. The rotating frame 3 is connected to the brackets 2 through bearings, which can realize flexible rotation and create conditions for multi-angle painting operations. When fixing the automotive trim panel, firstly, according to the size and shape of the trim panel, the adjusting seat 13 is slid along the outer wall of the rotating frame 3 to a suitable position. At the same time, the adjusting rod 4 slides up and down in the square groove 17 of the adjusting seat 13 to initially adjust the position of the vacuum suction cup 6. Then, the vacuum suction cup 6 is slid in the arc-shaped straight groove 18 on the outer wall of the adjusting rod 4. According to the specific shape of the trim panel and the adsorption requirements, its precise installation position is determined and fixed by tightening bolts. After the position adjustment is completed, the fixed threaded rod 16 is rotated, causing the fixed pad 15 connected to it to move, so that the fixed pad 15 fits tightly against the rotating frame 3, thereby stabilizing the position of the adjusting seat 13. Then, by placing the car trim panel in the predetermined position, the external vacuum pump is started, and the airflow is controlled by adjusting the air inlet on the outer wall of the threaded rod 5, so that the vacuum suction cup 6 generates suction force to firmly adhere and fix the trim panel. When it is necessary to adjust the angle of the trim panel for painting, the operator pulls the control block 11. The control block 11 causes the brake block 9 to overcome the elastic force of the spring 12 and slide down along the outer frame 10, disengaging from the tooth groove of the rotating gear 7. At this time, the rotating handle 8 is rotated, causing the rotating gear 7 to rotate. Since the rotating gear 7 is connected to the rotating frame 3 by a key, the rotating frame 3 rotates synchronously, realizing the adjustment of the trim panel angle. After adjusting to the appropriate angle, the control block 11 is released. Under the action of the restoring force of the spring 12, the brake block 9 re-inserts into the tooth groove of the rotating gear 7, fixing the position of the rotating frame 3 and ensuring that the trim panel remains stable during the painting process.
