[0002] Laser welding machines are used for laser welding of materials. They utilize high-energy laser pulses to locally heat a small area of ​​the material, melting it to form a specific molten pool, and then completing the welding. Laser welding machines are mainly used for welding thin-walled materials and precision parts. They can perform spot welding, lap welding, and sealing welding. Only simple post-weld processing is required. The weld quality is high, there are no pores, it can be precisely controlled, and it is easy to automate.

[0003] Existing laser welding machines have the following shortcomings: First, during operation, only one workstation is usually set up. When multiple workpieces need to be welded, the workpieces need to be changed continuously at the workstation, which reduces work efficiency. Second, after welding, the surface temperature of the workpiece will rise and waste will be generated. The lack of a workpiece and waste receiving device will make workpiece collection difficult and increase the cleaning burden. Third, there is no structure for clamping the workpiece, or the structure is too simple, which makes it inconvenient to weld different parts of the workpiece and poses safety hazards.

Detailed Implementation

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution:

[0023] The system includes a base plate 1, a welding machine body 2 fixedly connected above the base plate 1, a No. 1 motor 3 fixedly connected above the base plate 1, a drive shaft 4 fixedly connected coaxially to the output end of the No. 1 motor 3, a rotary table 5 fixedly connected coaxially above the drive shaft 4, a rotary table 5 having multiple receiving cavities, slots on both sides of the receiving cavity inner wall having slots at an angle, a receiving box 6 slidably connected between two slots, a number of protective covers 7 fixedly connected above the rotary table 5, a through hole on one side of the protective cover 7, a rotating mechanism above the rotary table 5, and a clamping mechanism above the rotary table 5.

[0024] Specifically, the waste generated during the welding process will fall into the receiving box 6. After welding is completed, the clamp on the workpiece is released, and the workpiece will fall into the receiving box 6. After the surface temperature of the workpiece drops, it will slide out of the receiving box 6, the workpiece will be taken out, and the waste will be cleaned up.

[0025] The rotating mechanism includes a second motor 8 and a rotating shaft 9. Multiple second motors 8 are fixedly connected above the rotating table 5. The rotating shaft 9 is coaxially fixedly connected to the output end of the second motor 8. The rotating shaft 9 is rotatably connected to the other side of the protective cover 7. The other end of the rotating shaft 9 is fixedly connected to a protective shell 10. A rectangular groove is opened on one side of the protective shell 10, and a small hole is opened on the other side of the protective shell 10. The small hole corresponds to the through hole. The rotating shaft 9 is set in the through hole and the small hole.

[0026] Specifically, when the welding angle needs to be adjusted, motor 8 is started. Motor 8 will drive the protective shell 10 to rotate through the rotating shaft 13, and drive the clamped workpiece to rotate together. When the workpiece rotates to the required angle, motor 8 is stopped, which facilitates welding of different parts of the workpiece.

[0027] The clamping mechanism includes a worm gear 11 and a crank handle 12. The worm gear 11 is rotatably connected to the other side of the protective shell 10, and the crank handle 12 is fixedly connected to the other side of the worm gear 11. The worm gear 11 is rotatably connected to the protective cover 7. A connecting shaft 13 is rotatably connected between the two inner walls of the protective cover 7. A worm wheel 14 is coaxially fixedly connected to one end of the connecting shaft 13. The worm wheel 14 meshes with the worm gear 11. A first gear 15 is coaxially fixedly connected to the other end of the connecting shaft 13. A rack 16 meshes below the first gear 15. The rack 16 is slidably connected to the outside of the rotating shaft 9. The rack 16 is located in the through hole and the small hole. A bidirectional threaded rod 17 is rotatably connected between the two inner walls of the protective shell 10. A second gear 18 is coaxially fixedly connected to the middle position of the bidirectional threaded rod 17. The second gear 18 meshes above the rack 16. Threaded sleeves 19 are threadedly connected to both ends of the bidirectional threaded rod 17. A clamping arm 20 is fixedly connected to one side of the threaded sleeve 19. Both clamping arms 20 are slidably connected in the rectangular groove.

[0028] Specifically, when welding a workpiece, the crank handle 12 is turned, which drives the worm wheel 14 to rotate via the worm gear 11. The worm wheel 14 drives the first gear 15 to rotate via the connecting shaft 13. The first gear 15 drives the gear 16 meshing with it to slide away from the second motor 8, thereby causing the second gear 18 meshing with the gear 16 to rotate. The second gear 18 causes the bidirectional threaded rod 17 to rotate, which in turn causes the two threaded sleeves 19 to drive the two clamping arms 20 to move closer to each other. After clamping the workpiece, the crank handle 12 is stopped from rotating. After welding is completed, the crank handle 12 is turned in the opposite direction, causing the two clamping arms 20 to move away from each other. After the clamping arms 20 release the workpiece, the crank handle 12 is stopped from rotating.

[0029] The working principle of this utility model is as follows:

[0030] When welding a workpiece is required, turn the crank handle 12. The crank handle 12 drives the worm gear 14 to rotate through the worm 11. The worm gear 14 drives the first gear 15 to rotate through the connecting shaft 13. The first gear 15 drives the rack 16 meshing with it to slide away from the second motor 8, thereby causing the second gear 18 meshing with the rack 16 to rotate. The second gear 18 causes the bidirectional threaded rod 17 to rotate, which in turn causes the two threaded sleeves 19 to drive the two clamping arms 20 to move closer to each other. After clamping the workpiece, stop turning the crank handle 12. After welding is completed, turn the crank handle 12 in the opposite direction, causing the two clamping arms 20 to move away from each other. After the clamping arms 20 release the workpiece, stop turning the crank handle 12.

[0031] When the welding angle needs to be adjusted, start motor 8. Motor 8 will drive the protective shell 10 to rotate through the rotating shaft 13, and drive the clamped workpiece to rotate together. When the workpiece is rotated to the required angle, stop motor 8, which facilitates welding of different parts of the workpiece.

[0032] Waste generated during welding will fall into the receiving box 6. After welding is completed, the clamp on the workpiece is released, and the workpiece will fall into the receiving box 6. After the surface temperature of the workpiece drops, it will slide out of the receiving box 6, the workpiece will be taken out, and the waste will be cleaned up.

[0033] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
