[0035] Example 2

[0036] Reference Figure 1 , Figure 4 and Figure 5 A welding calibration fixture for automotive rear skirt panels includes a pressing mechanism comprising a rotating gear 19, a moving rack 20, a third sliding plate 21, a guide moving wheel 22, a third cylinder 23, and a pressing positioning plate 24. A second fixed motor 18 is fixed to the bottom of both sides of the placement platform 1. The output end of the second fixed motor 18 is fixed to the rotating gear 19. One side of the rotating gear 19 is meshed with the moving rack 20. The top of the placement platform 1 has two sides slidably connected to the third sliding plate 21. The bottom of the third sliding plate 21 is rotatably connected to the guide moving wheel 22, which is located inside the placement platform 1 and slidably connected to it. The top of the third sliding plate 21 is fixed to the third cylinder 23, and the extension end of the third cylinder 23 is fixed to the pressing positioning plate 24.

[0037] The design of the pressing mechanism ensures that the third cylinder 23 moves precisely to the critical welding area of ​​the skirt plate.

[0038] A control panel 25 is fixed at the top of the placement platform 1 near the first cylinder 2. The control panel 25 and the equipment on the placement platform 1 are wirelessly connected via a 5G module. A rectangular through slot is provided inside the placement plate 3. The rectangular through slot is used to dissipate the heat generated by the first fixed motor 7 during operation. A power supply is provided inside the placement plate 3. The power supply is electrically connected to the first fixed motor 7.

[0039] The usage process of the automotive rear skirt welding calibration fixture provided by this utility model is as follows:

[0040] When the rear skirt of the car is placed on top of the placement plate 3 and the horizontal placement position of the skirt needs to be adjusted, the first fixed motor 7 is started through the control panel 25. The output end of the first fixed motor 7 drives the first bevel gear 8 to rotate. Since the first bevel gear 8 is meshed with the second bevel gear 9, the first transmission rod 10, which is fixedly connected to the second bevel gear 9, also rotates. Since the first transmission rod 10 is fixedly connected to the third bevel gear 11, the rotation of the first transmission rod 10 drives the third bevel gear 11 to rotate, which in turn causes the fourth bevel gear 12, which is meshed with the third bevel gear 11, to rotate as well.

[0041] Furthermore, since the fourth bevel gear 12 is fixedly connected to the bidirectional threaded rod 13 and the bidirectional threaded rod 13 is threadedly connected to the first sliding plate 14, the rotation of the fourth bevel gear 12 drives the two first sliding plates 14 to move closer to each other through the bidirectional threaded rod 13. Since the first sliding plate 14 is rotatably connected to the connecting plate 15 and the second sliding plate 16, which is rotatably connected to the connecting plate 15, is slidably connected to the placement plate 3, the movement of the first sliding plate 14 drives the auxiliary moving wheel 17 to rise and fall through the connecting plate 15. This causes the auxiliary moving wheel 17 at the top of the second sliding plate 16 to lift the rear skirt, making the movement of the rear skirt more convenient.

[0042] When the rear skirt panel moves to the appropriate position, the first fixing motor 7 is controlled to make the skirt panel stably placed on the placement plate 3. At this time, the second cylinder 4 is controlled by the control panel 25, so that the extension end of the second cylinder 4 drives the first clamping plate 5 to move, so that the first clamping plate 5 and the second clamping plate 6 fix the skirt panel longitudinally. The overall orientation of the placement plate 3 is controlled by the first cylinder 2.

[0043] To ensure more accurate positioning of the rear skirt when the pressing positioning plate 24 is pressed, the second fixed motor 18 is started via the control panel 25. The output of the second fixed motor 18 drives the rotating gear 19 to rotate. Since the moving rack 20 is meshed with the rotating gear 19 and fixedly connected to the third sliding plate 21, the rotation of the rotating gear 19 drives the third sliding plate 21 to move via the moving rack 20. This causes the third cylinder 23, which is fixedly connected to the third sliding plate 21, to change position, thus enabling the pressing positioning plate 24, which is fixed to the telescopic end of the third cylinder 23, to fix the rear skirt at different positions.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it.
