[0022] 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.

[0023] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a multifunctional laser welding workbench, including a workbench body 1. A fixed frame 3 is fixedly connected to the upper surface of the workbench body 1. A hydraulic cylinder 2 is fixedly connected inside the fixed frame 3. A gear 4 is fixedly connected to the output end of the hydraulic cylinder 2. A push plate 5 is fixedly connected to the outer wall of the gear 4. The lower surface of the push plate 5 is slidably connected to the upper surface of the workbench body 1. A spur gear 7 is meshed with the tooth end of the gear 4. A fixed shaft 6 is rotatably connected inside the spur gear 7. The outer wall of the fixed shaft 6 is fixedly connected to the inside of the fixed frame 3. A half gear 8 is meshed with the tooth end of the spur gear 7. A fixed shaft 9 is rotatably connected inside the half gear 8. The outer wall of the fixed shaft 9 is fixedly connected to the inside of the fixed frame 3. A rotating frame 10 is fixedly connected to the outer wall of the half gear 8. A clamping plate 11 is fixedly connected to the outer wall of the rotating frame 10. A support assembly is provided on the upper surface of the workbench body 1. The support assembly is used for auxiliary support.

[0024] Specifically, the worktable 1 fixes the position of the fixed frame 3, which in turn fixes the position of the hydraulic cylinder 2. Activating the hydraulic cylinder 2 causes the gear column 4 to reciprocate. This movement of the gear column 4 moves the push plate 5 under the support of the worktable 1. Simultaneously, the movement of the gear column 4 causes the toothed gear 7, which is meshed with the tooth end, to rotate under the support of the fixed shaft 6. The fixed frame 3 also fixes the position of the fixed shaft 6. At the same time, the rotation of the gear 7 causes the toothed half gear 8, which is meshed with the tooth end, to rotate synchronously under the support of the fixed shaft 9. The fixed frame 3 also fixes the position of the fixed shaft 9. The half gear 8 fixes the position of the rotating frame 10. Thus, when the half gear 8 rotates, the rotating frame 10 moves the clamping plate 11 to clamp the workpiece, ensuring the stability and accuracy of the workpiece during welding. This allows the laser beam to accurately irradiate the welding area, achieving high-quality welding.

[0025] Reference Figure 1 and Figure 3 The support assembly includes a support frame 12, the lower surface of which is fixedly connected to the upper surface of the worktable body 1. A hydraulic cylinder 13 is fixedly connected inside the support frame 12. A connecting block 21 is fixedly connected to the output end of the hydraulic cylinder 13. A sliding rod 16 is slidably connected inside the connecting block 21. A fixing block 22 is fixedly connected to the lower surface of the sliding rod 16. A laser welding machine 23 is fixedly connected to the lower surface of the fixing block 22. By adjusting the height of the laser welding machine 23, it can be ensured that the laser beam can always be focused on the surface of the workpiece, thereby achieving precise welding operation. At the same time, it also helps to improve work efficiency and reduce the time for manual adjustment.

[0026] Specifically, the workbench 1 serves to fix the position of the support frame 12, and the support frame 12 serves to fix the position of the hydraulic cylinder 13. The hydraulic cylinder 13 is activated to drive the connecting block 21 to move up and down. The movement of the connecting block 21 drives the fixed block 22 to move up and down through the sliding rod 16. The movement of the fixed block 22 drives the laser welding machine 23 to adjust its height.

[0027] Reference Figure 3 and Figure 4The outer wall of the fixed block 22 is fixedly connected to the second support shaft 24. The outer wall of the second support shaft 24 is rotatably connected to the second rotating plate 20. The outer wall of the second rotating plate 20 is rotatably connected to the second connecting plate 29. The inner wall of the second connecting plate 29 is rotatably connected to the connecting shaft 17. The outer wall of the connecting shaft 17 is fixedly connected to the outer wall of the connecting block 21. The outer wall of the connecting shaft 17 is rotatably connected to the first connecting plate 18. The outer wall of the first connecting plate 18 is rotatably connected to the outer wall of the second rotating plate 20. The outer walls of the second connecting plate 29 and the first connecting plate 18 are both rotatably connected to the first rotating plate 15. The inner wall of the first rotating plate 15 is rotatably connected to the first support shaft 14. The outer wall of the first support shaft 14 is fixedly connected to the outer wall of the support frame 12.

[0028] Specifically, the fixing block 22 serves to fix the position of the second support shaft 24. When the fixing block 22 moves up and down, the second support shaft 24 supports and drives the second rotating plate 20 to rotate. The rotation of the second rotating plate 20 drives the first connecting plate 18 and the second connecting plate 19 to rotate. At the same time, the connecting shaft 17 supports the position of the first connecting plate 18 and the second connecting plate 19. The connecting block 21 fixes the position of the connecting shaft 17. Thus, when the first connecting plate 18 and the second connecting plate 19 rotate, they drive the first rotating plate 15 to rotate. The first support shaft 14 supports the position of the first rotating plate 15. The support frame 12 fixes the position of the first support shaft 14.

[0029] Working principle: In use, the workpiece to be laser welded is first placed on the worktable 1. Then, the hydraulic cylinder 2 is activated to drive the gear column 4 to reciprocate. When the gear column 4 moves, it can drive the meshing spur gear 7 to rotate under the support of the fixed shaft 6. Then, the rotation of the spur gear 7 can drive the meshing half gear 8 to rotate under the support of the fixed shaft 9. Thus, the rotation of the half gear 8 can drive the rotating frame 10 to drive the clamping plate 11 to clamp the workpiece. At the same time, the movement of the gear column 4 can drive the push plate 5 and the clamping plate 11 to cooperate to clamp the workpiece, which helps to accurately position the workpiece, maintain the consistency of the workpiece position during the welding process, reduce errors, and improve the repeatability and reliability of welding. This is especially important for welding tasks in mass production.

[0030] When the height of the laser welding machine 23 needs to be adjusted, the hydraulic cylinder 21 is first activated to raise and lower the connecting block 21. As the connecting block 21 rises and falls, the sliding rod 16 drives the fixed block 22 and the laser welding machine 23 to rise and fall. Simultaneously, as the fixed block 22 moves, the support shaft 24 drives the rotating plate 20 to rotate. The rotating plate 20 then drives the connecting plate 19 and the connecting plate 18 to rotate together under the connection of the connecting shaft 17. The rotation of the connecting plate 19 and the connecting plate 18 drives the rotating plate 15 to rotate. The support shaft 14 supports the position of the rotating plate 15. This allows the laser welding machine 23 to be raised and lowered to adjust its height, enabling the laser welding head to be more precisely positioned for welding, thus improving welding accuracy. Furthermore, adjusting the height of the laser welding machine 23 optimizes the welding path and reduces the distance the laser beam travels during welding. This not only improves welding efficiency but also helps avoid accidental contact between the laser beam and non-welding areas of the workpiece, protecting the workpiece from damage.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
