Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, and in particular to a welding device for sheet metal processing. Background Technology

[0002] In the sheet metal processing industry, welding is one of the key processes, and its quality and efficiency directly affect the overall performance and production efficiency of sheet metal products. With the continuous development of the manufacturing industry, the requirements for sheet metal welding quality and production efficiency are increasing. However, most traditional equipment lacks positioning mechanisms, and operators often have to rely on experience and visual inspection to roughly position sheet metal materials. This leads to difficulties in ensuring consistent positioning of sheet metal materials during the welding process.

[0003] Furthermore, the height adjustment methods of traditional equipment are usually quite cumbersome. They either require complex manual operations, such as using wrenches and other tools to adjust multiple nuts and bolts, or the adjustment accuracy is low, making it difficult to meet the welding requirements of sheet metal materials of different thicknesses.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue that most traditional equipment lacks a positioning mechanism, operators often rely solely on experience and visual inspection to roughly position sheet metal materials. This leads to difficulties in ensuring consistent positioning of the sheet metal materials during welding. This application provides a welding device for sheet metal processing.

[0006] The welding device for sheet metal processing provided in this application adopts the following technical solution:

[0007] A welding device for sheet metal processing includes a base, on both sides of which are mounted movable frames. Each movable frame has a movable cavity in the middle of one end close to the other. A lead screw assembly is provided in the movable cavity. A clamping mechanism is installed on the lead screw assembly. The clamping mechanism includes a welding frame, a rotatable scissor arm inside the welding frame, and a clamping block fixed to the bottom of the scissor arm. The bottom end of the clamping block has an integral hook.

[0008] Preferably, the outer walls at both ends of the base are welded with brackets, and the brackets are internally threaded with threaded rods.

[0009] Preferably, one end of the threaded rod is movably connected to the outer wall of the movable frame, a set of slide rails are provided on the surface of the base, and movable blocks adapted to the slide rails are symmetrically fixed at the bottom of the movable frame.

[0010] Preferably, the lead screw assembly includes a lead screw and a slider, and a gear is fixed to the top end of the lead screw, the gear being rotatably connected to the inner wall of the movable frame.

[0011] Preferably, one side of the first gear is meshed with the second gear, and a motor is installed at the top of the outer wall of the movable frame. The output end of the motor passes through the inner wall of the movable frame and drives the second gear.

[0012] Preferably, one end of the slider extends outside the moving cavity and is fixed to the back wall of the welding frame. The top of the welding frame is symmetrically welded with fixing ears, and a reverse screw is rotatably provided between the two fixing ears. The top of the scissor arm is fixed with a sliding block, and the sliding block is adapted to the reverse screw.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This application utilizes a lead screw assembly to drive a slider to slide within a moving cavity, thereby adjusting the welding height of the welding frame. This allows for quick and precise height adjustment of the welding frame, enabling operators to easily change the welding position height according to welding process requirements, accommodating the welding needs of sheet metal materials of varying thicknesses. When the reverse lead screw inside the fixed ear is rotated, the two sliding blocks move relative to each other, causing the scissor arm to rotate. This allows the clamping blocks and hooks at the bottom to clamp and fix the sheet metal material, ensuring that it does not shift or wobble during welding, further improving clamping stability.

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a welding apparatus for sheet metal processing. (Refer to...) Figure 1The system includes a base 1, with movable frames 2 mounted on both sides of the base 1. Supports 4 are welded to the outer walls of both ends of the base 1. Threaded rods 5 are threaded internally connected to the supports 4, with one end of the threaded rod 5 movably connected to the outer wall of the movable frame 2. A set of slide rails 3 is formed on the surface of the base 1, and movable blocks adapted to the slide rails 3 are symmetrically fixed to the bottom of the movable frame 2. Rotating the threaded rods 5 allows the movable frame 2 to move along the slide rails 3, ensuring accurate welding positioning.

[0021] like Figures 2-3 As shown, each of the two movable frames 2 has a movable cavity 7 at the center of its closest end. A lead screw assembly is installed within the movable cavity 7, and a clamping mechanism is mounted on the lead screw assembly. The lead screw assembly includes a lead screw 6 and a slider 15. A gear 16 is fixed to the top of the lead screw 6, and the gear 16 is rotatably connected to the inner wall of the movable frame 2. A gear 17 meshes with one side of the gear 16. A motor is installed at the top of the outer wall of the movable frame 2, and the output end of the motor passes through the inner wall of the movable frame 2 and drives the gear 17. The motor drives the gear 17 to rotate and mesh with the gear 16, causing the lead screw 6 to rotate, thus allowing the slider 15 to slide within the movable cavity 7.

[0022] In this application, the clamping mechanism includes a welding frame 8, a scissor arm 11 rotatably disposed inside the welding frame 8, and a clamping block 12 fixed to the bottom of the scissor arm 11. The bottom end of the clamping block 12 is integrally provided with a hook 13. One end of the slider 15 extends outside the moving cavity 7 and is fixed to the back wall of the welding frame 8. Therefore, as the slider 15 rises and falls, it will push the welding frame 8 to adjust its position accordingly.

[0023] In this application, the top of the welding frame 8 is symmetrically welded with fixing ears 9, and a reverse screw 10 is rotatably provided between the two fixing ears 9. The top of the scissor arm 11 is fixed with a sliding block 14, which is adapted to the reverse screw 10. By adjusting the reverse screw 10, it can accommodate sheet metal materials of different widths. The design of the clamping block 12 and the hook 13 can also accommodate sheet metal edges of different shapes, achieving effective clamping whether the edge is straight or curved.

[0024] The implementation principle of a welding device for sheet metal processing in this application embodiment is as follows:

[0025] In use, the sheet metal material is placed on the base 1. Rotating the threaded rods 5 on both sides drives the moving frame 2 to move along the slide rail 3, approaching both sides of the sheet metal material. Then, the motor drives gear 2 17 to rotate and mesh with gear 1 16, causing the lead screw 6 to rotate accordingly. The slider 15 then slides in the moving cavity 7 and pushes the welding frame 8 to adjust the welding height accordingly. Subsequently, by rotating the reverse lead screw 10 inside the fixed ear 9, the two sliding blocks 14 move relative to each other, which drives the scissor arm 11 to rotate, operating the bottom clamping block 12 and hook 13 to clamp and fix the sheet metal material, thus facilitating the corresponding welding operation on the sheet metal material.

[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
