Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0022] A support fixture for pre-assembling automotive door panels disclosed by the present utility model is mainly applied to the scenario where when a traditional support fixture for pre-assembling automotive door panels is used, the position of the fixture is fixed, and when supporting door panels of different models, the fixation is unstable, and when the fixture in the central position is not used, it is not conducive to supporting other positions of the door panel, and the adaptability is poor.

[0023] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A support fixture for pre-assembling automotive door panels, comprising a bottom plate 1 and a fixture body 8. Both sides of the outer wall of the top of the bottom plate 1 are provided with first electric slide rails 2. Two arc-shaped grooves 3 are opened at the central position of the outer wall of the top of the bottom plate 1. It further includes:

[0024] Adjusting mechanism: The adjusting mechanism is respectively located on the two first electric slide rails 2;

[0025] A third slider 16 is slidably connected to the inner wall of the arc-shaped groove 3. The same connection box 9 is fixedly connected to the outer walls of the tops of the two third sliders 16. A third electric slide rail is provided on the inner wall of the connection box 9. A connection block 17 is slidably connected to the inner wall of the third electric slide rail. A connection plate 13 is fixedly connected to the outer wall of the top of the connection block 17. A fourth electric slide rail is provided on the inner wall of the connection plate 13. Four fourth sliders are slidably connected to the inner wall of the fourth electric slide rail. A second limiting plate 14 is fixedly connected to the outer wall of the top of the fourth slider. A rotating rod 15 is provided at the central position of the outer wall of the bottom of the connection box 9. Handles 10 are fixedly installed on both outer walls of the connection box 9.

[0026] In the specific working process, the adjusting mechanism adapts to door panels of different models. The connection box 9 in the middle position can rotate, so as to adapt to and support different door panels. When the door panel in the vertical direction does not need to be supported, the connection box 9 can be pulled by the handles 10 on both sides, so that under the action of the third slider 16, the connection box 9 slides inside the arc groove 3. At the same time, the rotating rod 15 at the bottom of the connection box 9 rotates, so that the connection box 9 slides to the required position to support the door panel. And the second limiting plate 14 moves to the adapted position under the action of the fourth electric slide rail, and limits and clamps the jig body 8 between the two second limiting plates 14. The four second limiting plates 14 can fix the three jig bodies 8 by moving positions, and change the fixed positions, so as to limit different sizes and different positions of the jig body 8.

[0027] Among them, the two arc grooves 3 are symmetrically distributed along the circumferential rotation trajectory of the rotating rod 15. In this way, when the connection box 9 slides inside the arc groove 3, the rotating rod 15 rotates synchronously, and then the rotation process of the connection box 9 is smooth and the position is better adjusted.

[0028] Among them, the two handles 10 are used in cooperation with the connection box 9. In this way, both the handles 10 on both sides can move the connection box 9, and the use position is wider. By pulling the wrench, the position of the connection box 9 is changed, so as to adapt to and support the door panel.

[0029] Refer to Figure 1 、 Figure 2 and Figure 3 In a preferred embodiment, the adjusting mechanism includes a first slider 4 slidably connected to the inner wall of the first electric slide rail 2. A mounting box 5 is fixedly connected to the outer wall of the top of the first slider 4. A bidirectional threaded rod 6 is provided on the inner wall of the mounting box 5. Two second sliders 11 are sleeved on the circumferential outer wall of the bidirectional threaded rod 6. One end of the bidirectional threaded rod 6 passing through the mounting box 5 is provided with a knob. A mounting plate 7 is fixedly connected to the outer wall of the top of the slider. A chute is provided on the outer wall of the top of the mounting plate 7. Two fifth sliders are slidably connected to the inner wall of the chute. A first limiting plate 12 is fixedly connected to the outer wall of the top of the two fifth sliders.

[0030] Specifically, the mounting boxes 5 on both sides move integrally through the first electric slide rail 2. When placing the jig body 8 on the mounting box 5, rotate the knob to drive the bidirectional threaded rod 6 to rotate, so that the two second sliders 11 move relatively or away from each other, so as to adapt to and place the position of the jig body 8 according to door panels of different models. When installing the jig body 8, the two first limiting plates 12 slide in the chute, so that the different-sized jig bodies 8 are fixed between the two first limiting plates 12, and the mounting box 5 can move in the front-back, left-right directions, so as to adapt to and install door panels of different models.

[0031] Among them, the fixture body 8 is respectively used in cooperation with the first limiting plate 12 and the second limiting plate 14. In this way, the fixture body 8 can be fixed and limited between the two first limiting plates 12 and the two second limiting plates 14, adapting to fixture bodies 8 of different sizes, facilitating replacement, and having simple clamping.

[0032] Among them, friction pads are provided on the outer walls of the first limiting plate 12 and the second limiting plate 14 on the side close to the fixture body 8. In this way, when the first limiting plate 12 and the second limiting plate 14 clamp the fixture body 8, the friction pads increase the friction, making the fixture body 8 more stable.

[0033] Working principle: During use, according to the size of the door panel and the position where the door panel needs to be placed, the required fixture body 8 is respectively placed between the two first limiting plates 12 and the two second limiting plates 14 for limiting and fixing. Then, by rotating the knob, the bidirectional threaded rod 6 is driven to rotate, so that the two second sliders 11 move relatively or away from each other, enabling the position of the fixture body 8 on the first limiting plate 12 to be adaptively moved. Then, under the action of the first electric slide rail 2, the fixture bodies 8 at the four corners adaptively support the door panel. Then, at the central position, the position where the door panel needs to be supported is rotated. By pulling the handles 10 on both sides, the connection box 9 slides inside the arc-shaped groove 3 under the action of the third slider 16. At the same time, the rotating rod 15 at the bottom of the connection box 9 rotates, enabling the connection box 9 to slide to the required position to support the door panel, and then the assembly work of the door panel is carried out.

[0034] As described above, it is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. The substitution may be the substitution of part of the structure, device, and method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present utility model and its inventive concept should be covered within the protection scope of the present utility model.
