[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the laser welding equipment includes a worktable 1. A part fixing mechanism is installed on the top of the worktable 1, and a laser welding mechanism is also installed on the top of the worktable 1. The part fixing mechanism includes two symmetrically arranged slide rails 6. A mounting plate 7 is slidably connected to the top of the two slide rails 6. A connecting frame 8 is fixedly connected to the top of the mounting plate 7. A first reduction motor 9 is fixedly connected to the top of the mounting plate 7. The gearbox of the first reduction motor 9 is located inside the connecting frame 8. A screw 10 is fixedly connected to the output end of the gearbox of the first reduction motor 9.

[0022] A limiting seat 13 is fixedly connected to the outer side of the bottom of the screw 10. The top of the connecting frame 8 is provided with a hole that matches the limiting seat 13. A part is provided on the outer side of the top of the screw 10. A connecting sleeve 14 is threadedly connected to the outer side of the top of the screw 10, and a pressure ring 15 is threadedly connected to the outer side of the top of the screw 10. The pressure ring 15 is located above the connecting sleeve 14.

[0023] When installing the ring-shaped part to be welded, the part is placed outside the screw 10 through its own hole. Then the part is on top of the limiting seat 13. The position of the part is then finely adjusted to align the welding point. The connecting sleeve 14 is then connected to the screw 10 to position the part. The pressure ring 15 is then connected to the screw 10 to contact the connecting sleeve 14 and lock the connecting sleeve 14 to prevent the part from loosening or shifting. During the welding process, the first reduction motor 9 drives the screw 10 to rotate, which in turn drives the part to rotate, so that the laser welding mechanism can perform laser welding on the overlapping part.

[0024] An electric push rod 11 is fixedly connected to the top of the workbench 1. The output end of the electric push rod 11 is connected to one side of the mounting plate 7. A plastic steel chain 12 is fixedly connected to the top of one end of the mounting plate 7. The plastic steel chain 12 is fixedly connected to the top of the workbench 1 through an external frame. When the electric push rod 11 is turned, its output end pushes the mounting plate 7 to slide on the slide rail 6, thereby making the parts to be welded closer to or further away from the laser welding mechanism, and making it easier for the staff to fix the parts. The plastic steel chain 12 will pull the mounting plate 7 as it moves, ensuring the stability of the movement of the mounting plate 7.

[0025] like Figure 1 and Figure 4As shown, the laser welding mechanism includes a first linear motor guide rail 2, a first slider 3 slidably connected to the outer side of the top of the first linear motor guide rail 2, a second linear motor guide rail 4 fixedly connected to the top of the first slider 3, and a second slider 5 slidably connected to the outer side of the second linear motor guide rail 4.

[0026] A second reduction motor 16 is fixedly connected to one side of the second slider 5. A laser generator 17 is fixedly connected to the output end of the second reduction motor 16. A welding head 18 is fixedly connected to the output end of the laser generator 17.

[0027] The first linear motor guide rail 2 rotates, allowing the first slider 3 to move laterally, thereby adjusting the lateral position of the welding head 18. The second linear motor guide rail 4 rotates, allowing the second slider 5 to move longitudinally, thereby adjusting the longitudinal position of the welding head 18 so that the welding head 18 can move closer to or further away from the part to be welded. The second motor 16 rotates, and its output end drives the laser generator 17 to rotate, thereby adjusting the angle of the welding head 18 to meet the welding requirements at different angle positions.

[0028] like Figure 5 As shown, a housing 19 is installed on the top of the workbench 1. An observation window 20 is provided on the bottom of one side of the housing 19. A PLC controller 21 is fixedly connected to the top of one side of the housing 19. A door is hinged to the side of the housing 19. The observation window 20 is used to observe the welding process of the parts. The PLC controller 21 is used to automatically control the electrical components. The door is used to open the housing 19 to pick up and put down the parts.

[0029] This utility model provides a laser welding device, the specific working principle of which is as follows: First, the part is placed on the outside of the screw 10 through its own hole. Then, the part is placed on top of the limiting seat 13. Next, the position of the part is finely adjusted to align the welding point. Then, the connecting sleeve 14 is connected to the screw 10 to position the part. Then, the pressure ring 15 is connected to the screw 10 to contact the connecting sleeve 14 and lock the connecting sleeve 14 to prevent the part from loosening or shifting. Then, the electric push rod 11 is rotated, and its output end pushes the mounting plate 7 to slide on the slide rail 6, thereby bringing the part to be welded closer to the laser welding mechanism. Then, it is rotated by the first linear motor guide rail 2. The first slider 3 can move laterally, thereby adjusting the lateral position of the welding head 18. The second linear motor guide rail 4 rotates, allowing the second slider 5 to move longitudinally, thereby adjusting the longitudinal position of the welding head 18 so that it is close to the part to be welded. The second motor 16 then rotates, and its output end drives the laser generator 17 to rotate, thereby adjusting the angle of the welding head 18. At this time, the laser generator 7 is activated, and it emits a laser beam through the welding head 18 to weld the overlapping parts. During this process, the first reduction motor 9 drives the screw 10 to rotate, thereby driving the part to rotate, so that the welding head 18 sequentially performs laser welding on the overlapping parts of the parts.
