Description

Technical Field

[0001] This utility model relates to the field of welding-related equipment technology, and in particular to a dual-station synchronous coordinated welding flipping mechanism. Background Technology

[0002] Welding is a common joining process in manufacturing. By heating, pressurizing, or both, the joining parts of two or more workpieces are made to achieve atomic bonding, thereby forming a stable connection. It is widely used in machinery, automobiles, steel structures and other fields. The dual-station synchronous coordinated welding flipping mechanism is a special equipment to assist welding operations. It has two working stations and can realize synchronous coordinated operation of the two stations. It can also drive the workpiece to flip to a suitable welding angle, providing convenience for welding operations.

[0003] Existing welding flipping structures are mostly single-station or simple double-station designs. When using them, the workpiece needs to be fixed manually with ordinary clamps. The existing structures take a long time to fix the workpiece, have poor stability, and the workpiece is prone to shaking. During welding, defects such as weld seam misalignment and undercut are likely to occur, resulting in low welding accuracy and making it difficult to adapt to the needs of mass production. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dual-station synchronous coordinated welding flipping mechanism, which aims to improve the problem of easy shaking when fixing workpieces, resulting in defects such as weld seam offset and undercut.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-station synchronous coordinated welding flipping mechanism, including a worktable, a fixture on the upper surface of the worktable, a mounting base fixedly connected to the upper surface of the fixture, a connecting plate rotatably connected to the inner wall of the mounting base, a handle rotatably connected to the outer wall of the connecting plate, a lower pressure plate rotatably connected to the inner wall of the handle, the outer wall of the lower pressure plate rotatably connected to the inner wall of the mounting base, a pressure head slidably connected to the inner wall of the lower pressure plate, a nut threadedly connected to the outer wall of the pressure head, the lower surface of the nut abutting against the upper surface of the lower pressure plate, and a driving assembly on the outer wall of the worktable for rotating the workpiece.

[0006] The above technical solution involves pressing the handle, which rotates on the inner wall of the mounting base via a connecting plate. When the handle rotates, it drives the lower pressure plate to press down, causing the pressure head to press down and fix the workpiece as the lower pressure plate moves. This achieves rapid fixation of the workpiece, ensuring its stability and preventing wobbling. It also avoids defects such as weld seam offset and undercut caused by displacement during welding, ensuring welding accuracy and meeting the needs of mass production.

[0007] Preferably, the drive assembly includes a connecting shaft, one end of which is fixedly connected to the outer wall of the worktable, a displacement base is rotatably connected to the outer wall of the connecting shaft, a motor is fixedly connected to the inner wall of the displacement base, and the output end of the motor is fixedly disposed at the other end of the connecting shaft.

[0008] Preferably, the inner wall of the displacement base is slidably connected to a housing, one end of a spring is fixedly connected inside the housing, and the other end of the spring is fixedly connected to a T-shaped shaft.

[0009] Preferably, the outer wall of the T-shaped shaft is slidably connected to the inside of the housing, and the outer wall of the housing is slidably connected to the inside of the displacement base.

[0010] Preferably, the inner side of the displacement base is slidably connected to a sliding shaft, the outer wall of the sliding shaft abuts against the outer wall of the T-shaped shaft, and a limit plate is slidably connected to the outer wall of the sliding shaft.

[0011] Preferably, the outer wall of the limiting disk is slidably connected to the inside of the displacement base one, and one end of the second spring is fixedly connected to the outer wall of the limiting disk, while the other end of the second spring is fixedly connected to the inside of the displacement base one.

[0012] Preferably, a base plate is fixedly connected to the lower surface of the displacement base, an operating box base is fixedly connected to the upper surface of the base plate, and a robot arm is fixedly connected to the upper surface of the operating box base.

[0013] Preferably, a displacement base two is fixedly connected to the upper surface of the base plate, the inner wall of the displacement base two is fixedly connected to the outer wall of the motor, the interior of the displacement base two is rotatably connected to the outer wall of the connecting shaft, a workbench two is fixedly connected to the outer wall of the connecting shaft, and a tooling two is provided on the upper surface of the workbench two.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the workpiece is quickly fixed by the cooperation between the workbench, tooling, mounting base, connecting plate, handle, lower pressure plate, pressure head and nut. This helps to ensure that the workpiece is stable and does not shake, avoids defects such as weld seam offset and undercut caused by displacement during welding, ensures welding accuracy, and meets the needs of mass production.

[0015] 2. In this utility model, the mutual cooperation between the outer shell, spring one, T-shaped shaft, sliding shaft, limiting plate and spring two achieves the effect of quick disassembly of the displacement base. This is beneficial for maintenance without having to remove bolts, greatly shortens downtime, facilitates internal inspection and troubleshooting, and achieves the effect of ensuring safe operation of equipment and saving costs.

[0018] 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.

[0019] Reference Figures 1-3 An embodiment of this utility model provides a dual-station synchronous coordinated welding flipping mechanism, including a workbench 1, a fixture 2 on the upper surface of the workbench 1, a mounting base 3 fixedly connected to the upper surface of the fixture 2, a connecting plate 4 rotatably connected to the inner wall of the mounting base 3, a handle 5 rotatably connected to the outer wall of the connecting plate 4, a lower pressure plate 6 rotatably connected to the inner wall of the handle 5, a pressure head 7 slidably connected to the inner wall of the lower pressure plate 6, a nut 8 threadedly connected to the outer wall of the pressure head 7, the lower surface of the nut 8 abutting against the upper surface of the lower pressure plate 6, and a driving assembly on the outer wall of the workbench 1 for rotating the workpiece. Specifically, the surface of the workbench 1 allows for the free installation and switching of welding fixture 2. Fixture 2 features a hollow structure with internal reinforcing ribs to ensure strength. The hollow design ensures the welding torch can operate normally. Fixture 2 supports and fixes the mounting base 3. Pulling the handle 5 downward causes the lower pressure plate 6 to rotate on the inner wall of the mounting base 3, thus moving the pressure head 7 towards the workpiece. Rotating the nut 8 adjusts the clamping stroke of the pressure head 7 according to the workpiece height. When the lower pressure plate 6 moves to a certain position, it will drive the pressure head 7... The workpiece is clamped, and the relative position of the connecting plate 4, handle 5 and mounting base 3 puts the mechanism in a self-locking state. Even if the external force on handle 5 is removed, the fixture can still rely on the self-locking mechanism to stably clamp the workpiece, thus achieving rapid fixation of the workpiece, ensuring that the workpiece is stable and does not shake, avoiding defects such as weld seam offset and undercut caused by displacement during welding, ensuring welding accuracy, and achieving the effect of adapting to the needs of mass production. Pulling handle 5 upwards causes the lower pressure plate 6 to disengage from the self-locking state, so that the pressure head 7 is driven by the lower pressure plate 6 to disengage from the surface of the workpiece, thereby quickly releasing the workpiece.

[0020] Reference Figure 2 and Figure 4 The drive assembly includes a connecting shaft 9, one end of which is fixedly connected to the outer wall of the worktable 1, and a displacement base 10 is rotatably connected to the outer wall of the connecting shaft 9. A motor 11 is fixedly connected to the inner wall of the displacement base 10, and the output end of the motor 11 is fixedly located at the other end of the connecting shaft 9. Specifically, the worktable 1 supports and fixes the connecting shaft 9, and the displacement base 10 supports and fixes the motor 11, ensuring the stability of the motor 11 during operation. When the motor 11 starts, it drives the worktable 1 to rotate synchronously through the connecting shaft 9 at the output end, thereby causing the worktable 1 to flip to the required weld position.

[0021] Reference Figure 1 , Figure 4 and Figure 5 The inner wall of the displacement base 10 is slidably connected to the outer shell 12. One end of the spring 13 is fixedly connected to the inside of the outer shell 12. The other end of the spring 13 is fixedly connected to the T-shaped shaft 14. The outer wall of the T-shaped shaft 14 is slidably connected to the inside of the outer shell 12. The outer wall of the outer shell 12 is slidably connected to the inside of the displacement base 10. The inner wall of the displacement base 10 is slidably connected to the sliding shaft 15. The outer wall of the sliding shaft 15 abuts against the outer wall of the T-shaped shaft 14. The outer wall of the sliding shaft 15 is slidably connected to the limiting disk 16. The outer wall of the limiting disk 16 is slidably connected to the inside of the displacement base 10. One end of the spring 17 is fixedly connected to the outer wall of the limiting disk 16. The other end of the spring 17 is fixedly connected to the inside of the displacement base 10. Specifically, pressing the sliding shaft 15 slides inside the displacement base 10, causing the T-shaped shaft 14 to be pushed as it slides. The T-shaped shaft 14 then slides synchronously inside the outer casing 12 and disengages from the displacement base 10, thus releasing the fixation on the outer casing 12. This allows for replacement or repair of the base's interior. The sliding shaft 15 supports and fixes the limiting plate 16, which in turn fixes one end of the second spring 17. The displacement base 10 fixes the other end of the second spring 17. Releasing the pressed sliding shaft 15 causes the spring force of the second spring 17 to support the limiting plate 16. The push causes the limit plate 16 to move, which in turn drives the sliding shaft 15 to slide and reset synchronously. One end of the spring 13 is fixed by the outer shell 12, and the other end of the spring 13 is fixed by the T-shaped shaft 14. After the sliding shaft 15 resets, the pushing force on the T-shaped shaft 14 is released, allowing the T-shaped shaft 14 to re-enter the interior of the displacement base 10 by the elastic force of the spring 13, and fix the outer shell 12. This allows for quick disassembly of the displacement base, eliminating the need to remove bolts during maintenance, significantly reducing downtime, facilitating internal inspection and troubleshooting, and achieving the effect of ensuring safe equipment operation and saving costs.

[0022] Reference Figure 1 and Figure 6 A base plate 18 is fixedly connected to the lower surface of the displacement base 10, an operating box base 19 is fixedly connected to the upper surface of the base plate 18, a robot arm 20 is fixedly connected to the upper surface of the operating box base 19, a displacement base 21 is fixedly connected to the upper surface of the base plate 18, the inner wall of the displacement base 21 is fixedly connected to the outer wall of the motor 11, the interior of the displacement base 21 is rotatably connected to the outer wall of the connecting shaft 9, a worktable 22 is fixedly connected to the outer wall of the connecting shaft 9, and a tooling 23 is provided on the upper surface of the worktable 22. Specifically, the base plate 18 supports and fixes the displacement base 10, the operating box base 19, and the robot arm 20, which can weld the workpiece. The base plate 18 also supports and fixes the displacement base 21, which in turn supports and fixes the motor 11. The worktable 22 supports and fixes the connecting shaft 9. When the motor 11 starts, the connecting shaft 9 at the output end drives the worktable 22 to rotate synchronously. In conjunction with the rotating component on the other side, it enables simultaneous flipping welding at two workstations, meeting different welding requirements.

[0023] Working principle: When the device is needed, place the workpiece on the surface of fixture 2. Adjust the pressure head 7 by rotating the nut 8 according to the height of the workpiece. Press the handle 5 and rotate it on the inner wall of the mounting base 3 through the connecting plate 4. When the handle 5 rotates, it will drive the lower pressure plate 6 to press down. When the lower pressure plate 6 moves, it will drive the pressure head 7 to press down and fix the workpiece. The relative position of the connecting plate 4, the handle 5 and the mounting base 3 makes the mechanism in a self-locking state. When the external force on the handle 5 is removed, the fixture can also stably clamp the workpiece, which can realize the rapid fixation of the workpiece, ensure that the workpiece is stable and does not shake, avoid defects such as weld seam offset and undercut caused by displacement during welding, ensure welding accuracy, and achieve the effect of adapting to the needs of mass production. After the workpiece is fixed, a work platform is set on each of the left and right sides of the operating box base 19. Starting the motor 11 on the inner wall of the displacement base one 10 and displacement base two 21 rotates the connecting shaft 9 at the output end, causing the worktable two 22 and worktable one 1 to rotate synchronously, allowing the workpiece to be flipped. The operating box base 19 is then activated, and the robotic arm 20 welds the workpiece, achieving simultaneous flipping welding at two stations to meet different welding needs. Pressing the sliding shaft 15 pushes the T-shaped shaft 14 inside the displacement base one 10, causing the T-shaped shaft 14 to disengage from the displacement base. From inside the base 10, the outer casing 12 can be removed to replace or repair the internal parts of the device. By releasing the pressed sliding shaft 15, the spring force of the second spring 17 pushes the limiting plate 16, causing the sliding shaft 15 to reset and release the pushing force on the T-shaped shaft 14. Then, the T-shaped shaft 14, through the spring force of the first spring 13, re-enters the interior of the displacement base 10 to fix the outer casing 12. This allows for quick disassembly of the displacement base. During maintenance, there is no need to laboriously remove the bolts, which greatly shortens downtime, facilitates internal inspection and troubleshooting, and achieves the effect of ensuring safe equipment operation and saving costs. In practical use, this equipment can not only quickly fix the workpiece, ensuring its stability and preventing it from shaking, thus avoiding defects such as weld seam displacement and undercut caused by displacement during welding, and ensuring welding accuracy to meet the needs of mass production, but also quickly disassemble the displacement base. During maintenance, there is no need to laboriously remove the bolts, which greatly shortens downtime, facilitates internal inspection and troubleshooting, and achieves the effect of ensuring safe operation of the equipment and saving costs.
