Description
Technical Field

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It is one of the important applications of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses into the interior through heat conduction. By controlling parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts.
[0003] In existing technologies, the angle of the welded parts is usually fixed and cannot be changed during the welding process. The welded parts may have various complex shapes and sizes. If the welding angle cannot be flexibly adjusted, it will not be able to meet the diverse welding requirements, which may lead to poor welding quality of the welded joint and defects in the weld, such as lack of fusion, slag inclusion, porosity, etc., affecting the mechanical properties of the welded joint.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 - Figure 6 This utility model provides a technical solution for an angle rotation device for a laser welding machine:
[0024] In the embodiments of this utility model, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The system includes a housing 1 and a first mounting shell 2. A fixing plate 3 is mounted on the top of the first mounting shell 2. A rotating shaft 4 is rotatably connected to the top of the fixing plate 3. A first gear rod 5, a second gear rod 6, and a third gear rod 7 are rotatably connected to the outer wall of the rotating shaft 4. A rotating rod 8 is rotatably connected to one end of each of the three gear rods 5, 6, and 7. A mounting plate 9 is rotatably connected to one end of each of the three rotating rods 8. A first motor 10 is mounted on one side of the top of the fixing plate 3. A main gear 11 is rotatably connected to the top of the first motor 10. A lifting assembly is mounted on the bottom of the main gear 11. The lifting assembly includes a base plate 12 installed inside the first mounting shell 2. A telescopic rod 13 is mounted on one side of the top of the base plate 12. A first slider 14 is fixedly connected to one end of the telescopic rod 13. A push plate 15 is slidably connected to the outer wall of the first slider 14. Four support rods 16 are mounted on the bottom of the push plate 15.
[0025] It should be noted that: the first mounting shell 2, as the main body of the component, provides stable support for the component. The rotating shaft 4, which is fixedly connected to the top of the fixing plate 3, provides good stability when the first gear rod 5, the second gear rod 6, and the third gear rod 7 are rotated and connected to the rotating shaft 4. One end of the first gear rod 5, the second gear rod 6, and the third gear rod 7 are respectively rotatably connected to a rotating rod 8, and the other end of the rotating rod 8 is rotatably connected to the mounting plate 9. The top of the mounting plate 9 is equipped with a clamping assembly, which fixes the welded parts. The rotation of the first motor 10 drives the main gear 11 to mesh with one of the first gear rod 5, the second gear rod 6, and the third gear rod 7, thereby driving the mounting plate 9 to adjust different angles. The extension rod 13 pushes out the first slider 14, allowing the first slider 14 to slide on the guide rail opened on the inner wall of the push plate 15. The displacement of the first slider 14 allows the push plate 15 to push out the main gear 11, thereby enabling the main gear 11 to mesh with the first gear rod 5, the second gear rod 6, and the third gear rod 7.
[0026] See Figure 6 The housing 1 is equipped with a positioning assembly, which includes a second mounting shell 17 installed inside the housing 1. A second motor 18 is installed on the inner left side of the second mounting shell 17. One end of the second motor 18 is rotatably connected to a first lead screw 19. A guide rod 20 is rotatably connected to the outer wall of the first lead screw 19. A second slider 21 is slidably connected to the inner wall of the guide rod 20. A slide rod 22 is slidably connected to the inner wall of the second slider 21. One end of the slide rod 22 is connected to a guide block 23. A second lead screw 24 is rotatably connected to the inner wall of the guide block 23. A third motor 25 is rotatably connected to one end of the second lead screw 24. The top end of the second slider 21 is fixedly connected to the first mounting shell 2.
[0027] It should be noted that: the rotation of the second motor 18 drives the first lead screw 19 to rotate, and the outer wall of the first lead screw 19 is rotatably connected to the guide rod 20. The inner wall of the guide rod 20 is slidably connected to the second slider 21, so the second slider 21 can slide smoothly on the inner wall of the guide rod 20. The inner wall of the second slider 21 is slidably connected to the slide rod 22, so the second slider 21 can move in the axial direction of the slide rod 22, that is, in the vertical and horizontal direction. The top of the second slider 21 is fixedly connected to the first mounting shell 2, so when the second slider 21 moves, it will simultaneously drive the first mounting shell 2 to move. One end of the slide rod 22 is connected to the guide block 23, and the inner wall of the guide block 23 is rotatably connected to the second lead screw 24. So when the third motor 25 rotates, the guide block 23 will move horizontally in the axial direction of the second lead screw 24, that is, in the left and right direction, thereby driving the slide rod 22 to pull the second slider 21 to move. This eliminates the errors that may be generated by a single transmission system and improves the overall positioning accuracy.
[0028] See Figure 1 A welding head 26 is installed on one side of the top of the box 1, and the bottom end of the welding head 26 is fixedly connected to the top of the box 1.
[0029] It should be noted that the fixed connection ensures the stability of the welding head 26 during operation and reduces welding errors caused by vibration or shaking.
[0030] See Figure 1 The bottom of the box 1 is equipped with multiple support legs 27, with a total of four support legs 27, and the bottom of the support legs 27 is equipped with anti-slip pads.
[0031] It should be noted that the four support legs 27 make the box 1 more stable during placement and use, preventing it from shaking or tilting, thus ensuring the smooth progress of welding operations.
[0032] Working principle: The first gear rod 5, the second gear rod 6, and the third gear rod 7 are rotatably connected to each rotating rod 8, and the other end of each rotating rod 8 is rotatably connected to the mounting plate 9. When the first motor 10 drives the main gear 11 to rotate, the first gear rod 5, the second gear rod 6, and the third gear rod 7, which mesh with the main gear 11, will drive the mounting plate 9 to adjust to different angles. By pushing the first slider 14 out through the telescopic rod 13, the first slider 14 can push the push plate 15 to move up or down, thereby adjusting the height of the main gear 11. By the main gear 11 meshing with the first gear rod 5, the second gear rod 6, and the third gear rod 7 respectively, the swing angle of the mounting plate 9 can be changed.
