Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a positioning tooling for cutting the side beam of a semi-trailer. Background Technology

[0002] The side beams of a semi-trailer are longitudinal support components installed on both sides of the semi-trailer frame. As an important part of the frame, their main functions are to bear the load of the cargo box, connect the frame crossbeams and side panels, and provide installation support for tires, the suspension system, and cargo box fixing devices. Side beams are typically made of high-strength steel (such as Q345B, Q690, etc.) or lightweight aluminum alloy materials, and are formed into closed or open cross-section structures through cold bending, welding, and other processes. Some models also have reinforcing ribs or anti-slip grooves on the side beams to improve torsional strength and stability. In logistics transportation, side beams need to withstand heavy loads and bumpy conditions, so their surfaces are often treated with galvanizing, powder coating, and other anti-corrosion treatments. With the increasing demand for lightweighting, using aluminum alloy side beams can reduce the vehicle's weight while maintaining strength, thus improving cargo carrying efficiency. This component is widely used in container semi-trailers, flatbed semi-trailers, and stake semi-trailers, and is a key component ensuring the overall structural strength and transportation safety of the semi-trailer.

[0003] In the manufacturing process of semi-trailer side beams, cutting of the side beams is necessary. In existing technology, there is no internal positioning or clamping device for the bent sheet metal parts. Since the sheet metal parts are relatively thin and long, without positioning fixtures, the dimensions of the machined holes will be off, leading to installation difficulties. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for cutting the side beam of a semi-trailer, which solves the problem of inconvenience in supporting and positioning the side beam workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for cutting the side beam of a semi-trailer, comprising multiple workbenches fixedly installed together, multiple support columns fixedly connected to the bottom of each workbench, support seats fixedly connected to the bottom of each support column, a reinforcing rod fixedly connected between adjacent support columns, a positioning plate one contacting the top of each workbench, a connecting block fixedly connected to the lower end of the positioning plate one, the connecting block being slidably connected to the workbench, a positioning plate two slidably connected to the top of the workbench and to the right of the positioning plate one, a positioning block fixedly connected to the inner side of the positioning plate two, the positioning block being slidably connected to the workbench, a clamping device provided on both the positioning plate one and the positioning plate two, a connecting mechanism provided on the connecting block, and a combination mechanism provided on the positioning plate two.

[0006] Preferably, the connecting mechanism includes a square block. A square block is fixedly connected to the inner side of the worktable, and the square block is slidably connected to the connecting block. A rotating rod is rotatably sleeved inside the worktable via a bearing. A rotating seat is fixedly connected to the top of the rotating rod. The rotating seat is rotatably connected to both the worktable and the connecting block. A fixing rod is fixedly connected inside the rotating seat. A spring is provided on the outer side of the fixing rod. An arc-shaped block is slidably sleeved on the outer side of the fixing rod, and the arc-shaped block is slidably connected to the connecting block. This connecting mechanism facilitates the disassembly of the positioning plate.

[0007] Preferably, one end of the spring is fixedly connected to the rotating seat, and the other end of the spring is fixedly connected to the arc-shaped block. The spring is designed so that its force can be applied to the arc-shaped block.

[0008] Preferably, the connecting block has an arc-shaped groove inside, and an arc-shaped block is slidably connected inside the arc-shaped groove. By designing the arc-shaped groove, the arc-shaped block can slide inside the arc-shaped groove.

[0009] Preferably, the combined mechanism includes a rotating shaft, which is rotatably connected inside the worktable. A first bevel gear is fixedly connected to the top of the rotating shaft, and a second bevel gear meshes with the outer side of the first bevel gear. A screw is fixedly connected to the right end of the second bevel gear, and the screw is rotatably connected to the worktable.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the design of positioning plate one and positioning plate two, can support and place the side beam. With the help of the clamping device, the side beam can be clamped and fixed. The inner edge of the side beam bending part is contoured, and the outer edge is clamped along the contoured edge to ensure the flatness of the side beam, resulting in higher precision of the machining hole. Through the insertion of the arc block and the arc groove, the connecting block can be limited, thereby realizing the connection between the connecting block and the worktable to achieve the purpose of fixing positioning plate one. Rotating the rotating rod can realize the separation of the rotating seat and the arc block from the connecting block, which can facilitate the disassembly and replacement of positioning plate one. It can be adapted to support and position workpieces of different shapes.

[0014] 2. This utility model limits the horizontal direction of the positioning plate two by designing the insertion of the positioning block and the worktable. It limits the vertical direction of the positioning plate two by inserting the rod and the slot. Thus, the positioning plate two can be connected and fixed to the worktable. When the rotating shaft drives the bevel gear one to rotate, the bevel gear two and the screw can be rotated. Then the rod and the slot can be separated. The positioning plate two can also be easily disassembled and replaced. It can also be flexibly adapted to support and position workpieces of different shapes. Attached Figure Description

One end of the spring 85 is fixedly connected to the rotating seat 83, and the other end of the spring 85 is fixedly connected to the arc-shaped block 86. By designing the spring 85, the force of the spring 85 can act on the arc-shaped block 86. The arc-shaped block 86 is slidably sleeved on the outer side of the fixed rod 84. The arc-shaped block 86 is slidably connected to the connecting block 6. An arc-shaped groove 87 is opened inside the connecting block 6. The arc-shaped block 86 is slidably connected inside the arc-shaped groove 87. By designing the arc-shaped groove 87, the arc-shaped block 86 can slide inside the arc-shaped groove 87.

[0026] When it is necessary to disassemble the second positioning plate 7, simply rotate the rotating shaft 91. The rotating shaft 91 drives the first bevel gear 92 to rotate, and the first bevel gear 92 drives the second bevel gear 93 and the screw 94 to rotate, causing the insertion rod 95 to make threaded movement. The insertion rod 95 will drive the guide block 97 to slide along the guide groove 98, eventually causing the insertion rod 95 to separate from the second positioning plate 7. Then, move the second positioning plate 7 upward and remove the positioning block 10 from the inside of the worktable 1 to remove the second positioning plate 7. Both the first positioning plate 5 and the second positioning plate 7 can be disassembled and replaced, which can flexibly adapt to the support and positioning of workpieces of different shapes.
