[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figure 1 , Figure 3 , Figure 4, the utility model provides an embodiment: a load-bearing fixture, including a workbench 1, which is the basic platform of the entire load-bearing fixture and is usually made of high-strength steel to ensure that it has sufficient strength and rigidity to support the workpiece. The workbench 1 is fixedly connected to the outside with a protective shell 2, and the workbench 1 is fixedly connected to the outside with a plurality of fixed blocks 3, and the fixed blocks 3 are fixedly connected to the outside with a driving assembly that provides power, and the workbench 1 is slidably connected to the outside with a connecting plate 6, which can slide smoothly along a predetermined track on the workbench 1, so that the connecting plate 6 can be flexibly adjusted according to different workpiece sizes and shapes. The connecting plate 6 is fixedly connected to the outside with an L-shaped plate 7, and the L-shaped plate 7 is fixedly connected to the outside with a limiting block 8, and the limiting block 8 is slidably connected to the outside with a limiting slot 9, and the limiting slot 9 cooperates with the limiting block 8 to form a stable limiting mechanism, which further ensures the stability and reliability of the entire structure. The limiting slot 9 is fixedly connected to the outside with a connecting ring 10.
[0033] The outside of the connecting ring 10 is fixedly connected to a concave plate 11, and the top of the workbench 1 is fixedly connected to a plurality of support rods 12. The support rods 12 are usually made of high-strength steel pipes or aluminum alloys and have good strength and rigidity. The outside of the support rods 12 is fixedly connected to a circular plate 13, which provides a flat working surface for placing workpieces or for use with other equipment. The support rods 12 are used to support the circular plate 13 so that it can be stably fixed above the workbench 1. The drive assembly includes a hydraulic cylinder 4, which provides a strong push-pull force through a hydraulic system to achieve precise positioning and fixation of the workpiece. The hydraulic cylinder 4 is fixed inside the protective shell 2, which can effectively protect the hydraulic cylinder 4 from damage from the external environment and is also convenient for maintenance and inspection. The outside of the hydraulic cylinder 4 is fixedly connected to a connecting rod 5, and the outside of the hydraulic cylinder 4 is fixedly connected to the inside of the protective shell 2.
[0034] Reference Figure 1 , Figure 2 , Figure 5The concave plate 11 is fixedly connected to the outside of a plurality of connecting plates 14, which are usually made of a solid metal material such as steel or aluminum alloy. Their shapes and sizes are designed according to specific usage requirements to provide stable connection and support. The connecting plate 14 is fixedly connected to the outside of a connecting rod 15, which is fixedly connected to the outside of the concave plate 11. This connection method ensures a firm connection between the connecting rod 15 and the concave plate 11, making the entire structure more stable and reliable. The connecting rod 15 is fixedly connected to the outside of a connecting rod 2 16, which is used to further extend and transmit torque. The connecting rod 2 16 is slidably connected to the outside of a sliding ring 17, which is slidably connected to the outside of the concave plate 11. The top of the connecting rod 2 16 is fixedly connected to a fixed plate 18, which is used to enhance the stability and rigidity of the entire structure. It is usually made of thick steel plates with regular shapes for easy installation and fixation.
[0035] The sliding ring 17 is slidably connected to the outside of the sliding block 19. A follower rod 20 is fixedly connected to the outside of the sliding block 19. The follower rod 20 is typically cylindrical and made of high-strength metal. It moves synchronously with the movement of the sliding block 19, thereby driving the other components to achieve corresponding movements. A spring 21 is sleeved on the outside of the follower rod 20. The spring 21 provides a certain elastic force, allowing the follower rod 20 to move while also acting as a buffer and shock absorber. A limit ring 22 is fixedly connected to the outside of the follower rod 20. The limit ring 22 is used to limit the range of motion of the follower rod 20, preventing excessive movement that could cause damage or malfunction. The limit ring 22 is typically made of a sturdy metal material and has a simple shape but important functions. A hollow block 23 is slidably connected to the outside of the follower rod 20. A bearing plate 24 is fixedly connected to the outside of the hollow block 23. The outside of the concave plate 11 is fixedly connected to the outside of the connecting ring 10, and the other end of the concave plate 11 is fixedly connected to the outside of the connecting plate 14.
[0036] Working principle: First, place the workpiece on the circular plate 13 above the workbench 1. The circular plate 13 provides a flat working surface for placing the workpiece or cooperating with other equipment. Then start the hydraulic cylinder 4 in the drive assembly. The hydraulic cylinder 4 provides a strong push and pull force through the hydraulic system. The outside of the hydraulic cylinder 4 is fixedly connected with a connecting rod 5. When the hydraulic cylinder 4 is working, it will generate a strong thrust or pull force, which is transmitted to the fixed block 3 through the connecting rod 5, thereby achieving precise positioning of the workpiece. During the working process, the connecting plate 6 slides smoothly along the predetermined track on the workbench 1, so that the connecting plate 6 can be flexibly adjusted according to different workpiece sizes and shapes. At the same time, the outside of the L-shaped plate 7 is fixedly connected to the limiting block 8, and the outside of the limiting block 8 is slidably connected to the limiting slot 9. The limiting slot 9 cooperates with the limiting block 8 to form a stable limiting mechanism, which further ensures the stability and reliability of the entire structure.
[0037] By fixing the hollow block 23 at the bottom of the bearing plate 24 to the concave plate 11, the follower rod 20 is slidably connected inside the hollow block 23, and a sliding block 19 made of wear-resistant material is fixed to the outside of the follower rod 20, which increases durability and ensures a firm connection with other components. By pushing the bearing plate 24, the concave plate 11 drives the hollow block 23 to move, and the follower rod 20 drives the spring 21 to move, and then the sliding block 19 slides on the connecting rod 16. When the sliding block 19 slides to the bottom of the connecting rod 16, the follower rod 20 drives the sliding ring 17 to move, thereby achieving quick disassembly and facilitating replacement and maintenance.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
