Electric cylinders are fixedly installed on the left and right sides of the fixed platform, and a fixed frame is fixedly installed on the right side of the electric cylinders. A welding machine is installed on the upper side of the fixed frame. This fixture can achieve plate flipping through the flipping fixing component. At the same time, the electric cylinders can push the fixed frame to move left and right, which can adjust the position of the welding machine according to the actual model and specifications of the plate, making it more versatile.

[0004] However, existing welding fixtures do not clamp the workpiece well, which makes the workpiece prone to shaking during the welding process, thus affecting the welding effect. Therefore, there is an urgent need in the market for a welding fixture for large-format products to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a welding fixture for large-format products, so as to solve the problem mentioned in the background art that the existing welding fixtures have poor clamping effect on the workpiece, which makes the workpiece easy to shake during the welding process, thereby affecting the welding effect of the workpiece.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A welding fixture for large-format products includes a worktable, a fixture block above the worktable, a mounting frame 1 above the worktable, a rotating seat 1 above the mounting frame 1, two rotating seats 1, a rotating rod 1 between the two rotating seats 1, a cylinder 2 above one side of the worktable, a connecting block 2 at one end of the cylinder 2, a rotating seat 2 on one side of the connecting block 2, two rotating seats 2, a rotating rod 2 between the two rotating seats 2, a mounting frame 2 above the fixture block, a rotating seat on one side of the inner wall of the mounting frame 2, a support frame on one side of the fixture block, a cylinder 4 on one side of the support frame, and a fixed seat 3 below the cylinder 4.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4 This utility model provides an embodiment of a welding fixture for large-format products, including a worktable 1. A plurality of fixture blocks 2 are arranged above the worktable 1, evenly distributed above the worktable 1. A mounting frame 4 is installed above the worktable 1, and two rotating seats 5 are installed above the mounting frame 4. A rotating rod 6 is installed between the two rotating seats 5. A cylinder 13 is installed above one side of the worktable 1, and a fixed seat 14 is installed below the cylinder 13. The fixed seat 14 and the cylinder 13 are rotatably connected by a connecting shaft 3 15. A connecting block 26 is provided at one end of the cylinder 13, and two rotating seats 12 are installed on one side of the connecting block 26. A rotating rod 2 is installed between the two rotating seats 12. 11. A mounting bracket 20 is installed above the tooling block 2. A rotating seat 22 is installed on one side of the inner wall of the mounting bracket 20. A support frame 27 is installed on one side of the tooling block 2. A cylinder 30 is installed on one side of the support frame 27. A fixed seat 31 is installed below the cylinder 30. The fixed seat 31 and the cylinder 30 are rotatably connected by a connecting shaft 2 32. The tooling block 2 allows for convenient placement of the workpiece. The rotating rod 21 can be rotated by the cylinder 2 13, which facilitates clamping of the workpiece. The support frame 27 allows for convenient installation of the cylinder 30, which effectively clamps the workpiece. It should be noted that, in order to save space and highlight the innovative elements of this patent, the working principle and process of clamping the workpiece are not described in detail in this patent.

[0020] See Figure 1 A cylinder 7 is installed on both sides of the rotating rod 6. A connecting block 8 is provided at one end of the cylinder 7. The connecting block 8 is fixedly connected to the rotating rod 6 by fixing screws. A fixing seat 9 is installed below the cylinder 7. The fixing seat 9 is rotatably connected to the cylinder 7 by a connecting shaft 10. A connecting plate 16 is installed on one side of the rotating rod 6. A pressure plate 17 is installed below the connecting plate 16. A connecting plate 18 is provided at one end of the rotating rod 11. A pressure plate 19 is provided at the lower end of the connecting plate 18. When the rotating rod 6 rotates, the connecting plate 16 drives the pressure plate 17 to rotate, thus pressing the workpiece. When the rotating rod 11 rotates, the connecting plate 18 drives the pressure plate 19 to rotate, thus pressing the workpiece. This makes it easy to fix the workpiece.

[0021] See Figure 1 and Figure 4 A cylinder 25 is installed on one side of the mounting bracket 20. A connecting seat 21 is provided at one end of the cylinder 25. The connecting seat 21 is rotatably connected to the rotating seat 22. A connecting plate 23 is provided at one end of the rotating seat 22. A pressure plate 24 is provided at the lower end of the connecting plate 23. The cylinder 25 can cause the connecting seat 21 to drive the rotating seat 22 to rotate, which in turn causes the connecting plate 23 to drive the pressure plate 24 to rotate, thereby pressing and clamping one end of the workpiece. The mounting bracket can be easily disassembled, allowing the mounting bracket 20 to be easily installed on different tooling blocks 2. The position of the pressure plate 24 can be easily adjusted, thereby better fixing the workpiece.

[0022] See Figure 1 and Figure 2 The support frame 27 has a connecting plate 28 installed inside. The lower end of the connecting plate 28 is provided with a pressure plate 29. The output end of the cylinder 30 is rotatably connected to the connecting plate 28. The cylinder 30 can make the connecting plate 28 rotate, so that the pressure plate 29 can limit and fix the workpiece.

[0023] See Figure 1 The workbench 1 has two mounting slots 101 inside. A rotating lead screw 3 is installed inside the mounting slot 101. A lead screw motor 301 corresponding to the rotating lead screw 3 is installed on one side of the outer wall of the workbench 1. A movable seat 302 is installed on the upper end of the rotating lead screw 3. The movable seat 302 is fixedly connected to the fixed seat 14. The lead screw motor 301 can rotate the rotating lead screw 3, thereby causing the movable seat 302 to drive the cylinder 13 to move, which in turn can move the rotating rod 11, thus allowing the position of the rotating rod 11 to be adjusted.

[0024] Working principle: In use, the workpiece is placed above the tooling block 2. Opening cylinder 7 causes rotating rod 6 to rotate, which in turn causes connecting plate 16 to rotate pressure plate 17. Simultaneously, opening cylinder 2 causes rotating rod 21 to rotate, which in turn causes connecting plate 28 to rotate pressure plate 29. Pressure plates 17 and 29 then easily press down on both sides of the workpiece. Opening cylinder 3 causes connecting seat 21 to rotate rotating seat 22, which in turn causes connecting plate 3 23 to rotate pressure plate 3 24. This allows pressure plate 3 24 to press down on one side of the workpiece. The workpiece is pressed down, and then the output end of cylinder 430 is opened to push the connecting plate 428 to rotate the pressure plate 429. The pressure plate 429 can press down on the other side of the workpiece, which can effectively press down the workpiece and prevent it from shaking during the welding process, thus affecting the welding effect. At the same time, the lead screw motor 301 is opened, which can rotate the lead screw 3, thereby moving the moving seat 302 to drive cylinder 213 to move, which can move the rotating rod 21. This allows the position of the rotating rod 21 to be adjusted, so that workpieces of different sizes can be clamped and fixed, thereby improving the welding effect.
