Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a fixed bracket for cutting trailer bodies, including a fixed box 1. A motor 2 is fixedly connected inside the fixed box 1. A first gear 3 is fixedly provided at the output end of the motor 2. A second gear 4 is meshed with the tooth end of the first gear 3. A bidirectional threaded rod 5 is fixedly connected inside the second gear 4. The outer wall of the bidirectional threaded rod 5 is rotatably connected inside the fixed box 1. A limit plate 7 is fixedly connected to the outer wall of the bidirectional threaded rod 5. A sliding plate 6 is threadedly connected to the outer wall of the bidirectional threaded rod 5. A fixed rod 8 is slidably connected inside the sliding plate 6. The outer wall of the fixed rod 8 is fixedly connected to the inside of the fixed box 1. A clamping plate 9 is fixedly connected to the outer wall of the sliding plate 6. A support assembly is provided on the lower surface of the fixed box 1.

[0024] Specifically, the fixing box 1 provides fixed support for the motor 2, which in turn drives the first gear 3 to rotate, which in turn drives the second gear 4 to rotate. The rotation of the second gear 4 simultaneously drives the bidirectional threaded rod 5 to rotate inside the fixing box 1. The fixing box 1 provides auxiliary support and limits the bidirectional threaded rod 5. The limiting piece 7 limits the sliding plate 6. The bidirectional threaded rod 5 drives the sliding plate 6 to slide on the outer wall of the fixing rod 8. The fixing box 1 provides fixed support for the fixing rod 8, which in turn provides auxiliary support and limits the sliding plate 6. The sliding plate 6 then drives the clamping plate 9 to clamp and fix the car body panel, thereby ensuring that the car body panel is stable and does not shift during cutting.

[0025] Reference Figure 2 and Figure 4The support assembly includes a support plate 10, the upper surface of which is fixedly connected to the lower surface of the fixed box 1, and an adjusting block 11 fixedly connected to the lower surface of the support plate 10; a triangular plate 12 is fixedly connected to the lower surface of the adjusting block 11, and a connecting column 13 is fixedly connected inside the triangular plate 12; a fixing frame 14 is rotatably connected to the outer wall of the connecting column 13, and the upper surface of the fixing frame 14 is attached to the lower surface of the support plate 10.

[0026] Specifically, the support plate 10 provides fixed support for the fixed box 1, the limiting post 20 drives the triangular plate 12 and thus the connecting post 13 to rotate inside the fixed frame 14, the fixed frame 14 limits the connecting post 13, the triangular plate 12 drives the adjusting block 11 and thus the support plate 10 to adjust the angle, and the fixed frame 14 provides auxiliary support for the support plate 10.

[0027] Reference Figure 4 A hydraulic cylinder 15 is fixedly connected inside the fixed frame 14, and a U-shaped block 16 is fixedly connected to the output end of the hydraulic cylinder 15. A slide rail 17 is slidably connected to the lower surface of the U-shaped block 16, and the lower surface of the slide rail 17 is fixedly connected to the inner bottom wall of the fixed frame 14. A limit rod 18 is fixedly connected inside the U-shaped block 16, and a push plate 19 is rotatably connected to the outer wall of the limit rod 18. A limit post 20 is fixedly connected inside the push plate 19, and the outer wall of the limit post 20 is rotatably connected to the inside of the triangular plate 12.

[0028] Specifically, the fixing frame 14 provides fixed support for the hydraulic cylinder 15, and the hydraulic cylinder 15 drives the U-shaped block 16 to slide on the upper surface of the slide rail 17. The fixing frame 14 provides fixed support for the slide rail 17, and the slide rail 17 provides auxiliary support and limit for the U-shaped block 16. The U-shaped block 16 drives the limit rod 18, which in turn drives the push plate 19 to move. As the push plate 19 moves, it drives the limit post 20 to rotate inside the triangular plate 12.

[0029] Working principle: When the bracket is needed, the motor 2 inside the fixing box 1 is started. The motor 2 drives the first gear 3 to rotate, which in turn drives the second gear 4 to rotate. At the same time, the rotation of the second gear 4 drives the bidirectional threaded rod 5 to rotate inside the fixing box 1. The bidirectional threaded rod 5 drives the sliding plate 6 to slide on the outer wall of the fixing rod 8. The sliding plate 6 then drives the clamping plate 9 to clamp and fix the car body panel, ensuring that the car body panel is stable and does not shift during cutting, thus improving cutting accuracy and operational safety.

[0030] The hydraulic cylinder 15 inside the fixed frame 14 is activated, which drives the U-shaped block 16 to slide on the upper surface of the slide rail 17. The U-shaped block 16 drives the limit rod 18, which in turn drives the push plate 19 to move. As the push plate 19 moves, it drives the limit post 20 to rotate inside the triangular plate 12. The limit post 20 drives the triangular plate 12, which in turn drives the connecting post 13 to rotate inside the fixed frame 14. Thus, the triangular plate 12 drives the adjusting block 11, which in turn drives the support plate 10 to adjust the angle. This bracket not only ensures that the car body plate is stable and without displacement during cutting, improving cutting accuracy and operational safety, but also adapts to steel plates of different thicknesses and deformations, enhancing the bracket's versatility and work efficiency. It can also achieve multi-dimensional precise cutting, meeting the needs of complex cutting processes, while avoiding repeated disassembly and adjustment of the bracket, significantly improving work efficiency and cutting quality.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
