The top end of the worm gear 8 is connected to the bottom end of the installation cavity 2. After a automotive part is welded, start the first servo motor 6 to drive the worm 7 to rotate, so as to drive the worm gear 8 to move. Then, under the limitation of the limit groove 9 and the limit block 10, use the worm gear 8 to drive the installation cavity 2 to rotate, and then drive the automotive part fixed on the fixed plate 3 to rotate, rotate it to one side of the laser welding machine body 4, and use the welding head 5 to perform welding treatment on it. At this time, the welded automotive part can be removed. Finally, fix the automotive part to be welded on the fixed plate 3. The baffle at one end of the fixed plate 3 can block the debris generated during welding to protect the staff, enabling the device to continuously weld automotive parts, thus greatly improving the working efficiency of the device during use.

[0020] The limiting structure includes a limiting groove 9 and a limiting block 10. The limiting groove 9 is formed inside the bottom plate 1, and a limiting block 10 is arranged inside the limiting groove 9. The top end of the limiting block 10 is connected to the bottom end of the installation cavity 2. The inner diameter of the limiting groove 9 is larger than the outer diameter of the limiting block 10. A sliding structure is formed between the limiting groove 9 and the limiting block 10. During use, by the mutual cooperation between the limiting groove 9 and the limiting block 10, the installation cavity 2 can be limited during rotation, making the rotation of the installation cavity 2 more stable.

[0021] The moving mechanism includes a second servo motor 11, a threaded rod 12, a threaded sleeve 13 and a guiding structure. The second servo motor 11 is installed on one side of the front end of the bottom plate 1, and the threaded rod 12 is installed on one side inside the bottom plate 1.

During use, start the second servo motor 11 to drive the threaded rod 12 to rotate. Therefore, under the limitation of the guiding groove 14 and the guiding block 15, the threaded rod 12 drives the threaded sleeve 13 to move, thereby driving the laser welding machine body 4 to move, and adjusting the laser welding machine body 4 to an appropriate position to make the use effect of the laser welding machine body 4 better.

The suction head 19 is installed outside the welding head 5, and one end of the hose 18 is connected to one end of the suction head 19. During use, start the fan 17. By the cooperation of the hose 18 and the suction head 19, the smoke generated during welding is adsorbed into the purification box 16, so that the staff will not inhale the smoke into the body and it is not easy to affect the physical health of the staff, thus greatly improving the practicability of the equipment during use.

[0024] Working principle: First, the staff fix the automotive parts above the fixed plate 3 respectively, and then start the second servo motor 11 to drive the threaded rod 12 to rotate. Therefore, under the limitation of the guiding groove 14 and the guiding block 15, the threaded rod 12 drives the threaded sleeve 13 to move, and then drives the laser welding machine body 4 to move, adjusting the laser welding machine body 4 to an appropriate position. After accommodation, start the laser welding machine body 4, and use the welding head 5 to perform welding treatment on the automotive parts. At this time, start the fan 17, and use the cooperation of the hose 18 and the suction head 19 to adsorb the fumes generated during welding into the interior of the purification box 16. When welding of one automotive part is completed, start the first servo motor 6 to drive the worm 7 to rotate, so as to drive the worm gear 8 to move. Then, under the limitation of the limiting groove 9 and the limiting block 10, the worm gear 8 drives the installation cavity 2 to rotate, and then drives the automotive parts fixed on the fixed plate 3 to rotate, rotating it to one side of the laser welding machine body 4, and using the welding head 5 to perform welding treatment on it.
