[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0031] As Figures 1 - 5 As shown, the present invention provides a laser welding machine, including a machine body 1, an operation box 6, and a stabilizing plate 4.

[0032] The following specifically describes the specific settings and functions of its adjusting device 7.

[0033] As Figures 2 - 5As shown, the adjusting device 7 includes a groove 701 opened on the surface of the operation box 6. A two-way lead screw 702 is rotatably connected to the surface of the groove 701. Two screw blocks 703 are threadedly connected to the surface of the two-way lead screw 702. Sliders 705 are fixedly connected to the surfaces of the two screw blocks 703. A chute 704 is opened on the surface of the stabilizing plate 4. The chute 704 is slidably connected to the slider 705. A screw rod 706 is threadedly connected to the surface of the stabilizing plate 4. The screw rod 706 is threadedly connected to the slider 705. A telescopic cover 707 is slidably connected to the surface of the operation box 6. The two ends of the telescopic cover 707 are respectively fixedly connected to the two screw blocks 703. The screw block 703 will drive the telescopic cover 707 to move along the surface of the operation box 6. At this time, the telescopic cover 707 can prevent the welding slag generated during welding from falling into the groove 701 and affecting the rotation of the screw block 703 on the two-way lead screw 702. Two balls 708 are rotatably connected to the surface of the stabilizing plate 4. Both of the two balls 708 are slidably connected to the operation box 6. The stabilizing plate 4 will drive the balls 708 to rotate. At this time, the balls 708 can reduce the friction between the stabilizing plate 4 and the operation box 6. A scale plate 709 is fixedly connected to the surface of the operation box 6. A number of scale grooves are opened on the surface of the scale plate 709. Place the welding pipe 5 on the stabilizing plate 4, and then observe the scale plate 709. According to the size of the welding pipe 5, it is convenient to adjust the distance between the two stabilizing plates 4. A rectangular groove 710 is opened on the surface of the two-way lead screw 702. A rectangular rod 711 is slidably connected to the surface of the rectangular groove 710. A turning handle 712 is fixedly connected to the surface of the rectangular rod 711. Insert the rectangular rod 711 on the turning handle 712 into the rectangular groove 710, and then rotate the turning handle 712. Then the turning handle 712 will drive the rectangular rod 711 to rotate. At the same time, the rectangular rod 711 will drive the rectangular groove 710 to rotate. Then the rectangular groove 710 will drive the two-way lead screw 702 to rotate. At this time, by the cooperation between the rectangular groove 710, the rectangular rod 711 and the turning handle 712, it is convenient to rotate the two-way lead screw 702. An elastic cord 713 is fixedly connected to the surface of the turning handle 712. The other end of the elastic cord 713 is fixedly connected to the operation box 6. The turning handle 712 will drive one end of the elastic cord 713 to move. At this time, the elastic cord 713 can prevent the turning handle 712 from being lost. A pointed cone 714 is fixedly connected to the surface of the rectangular rod 711. The pointed cone 714 is a stainless steel cone. The rectangular rod 711 will drive the pointed cone 714 to enter the rectangular groove 710. At this time, the pointed cone 714 can facilitate the insertion of the rectangular rod 711 into the rectangular groove 710.

[0034] The overall working principle is as follows. When welding the 5 - pass welded pipes of different sizes, first, the sliding groove 704 on the stabilizing plate 4 is engaged with the sliding block 705 on the screw block 703. Then, the screw rod 706 is rotated, and the stabilizing plate 4 and the sliding block 705 are fixed by the thread of the screw rod 706 itself. Next, the 5 - pass welded pipe is placed on the stabilizing plate 4. Then, the scale plate 709 is observed, and according to the size of the 5 - pass welded pipe, the distance between the two stabilizing plates 4 is conveniently adjusted. Then, the rectangular rod 711 on the turning handle 712 is inserted into the rectangular groove 710. Then, the turning handle 712 drives one end of the elastic rope 713 to move. At this time, the elastic rope 713 can prevent the turning handle 712 from being lost. At the same time, the rectangular rod 711 drives the pointed cone 714 into the rectangular groove 710. At this time, the pointed cone 714 can facilitate the insertion of the rectangular rod 711 into the rectangular groove 710. Then, the turning handle 712 is rotated. Then, the turning handle 712 drives the rectangular rod 711 to rotate. At the same time, the rectangular rod 711 drives the rectangular groove 710 to rotate. Then, the rectangular groove 710 drives the bidirectional lead screw 702 to rotate. At this time, by the cooperation between the rectangular groove 710, the rectangular rod 711, and the turning handle 712, the bidirectional lead screw 702 can be conveniently rotated. Then, the bidirectional lead screw 702 drives the two screw blocks 703 to move towards each other by means of its own thread. At the same time, the screw block 703 drives the telescopic cover 707 to move along the surface of the operation box 6. At this time, the telescopic cover 707 can prevent the welding slag generated during welding from falling into the groove 701 and affecting the rotation of the screw block 703 on the bidirectional lead screw 702. Then, the screw block 703 drives the sliding block 705 to move. At this time, the sliding block 705 drives the screw rod 706 to move. Then, the screw rod 706 drives the stabilizing plate 4 to move. At the same time, the stabilizing plate 4 drives the ball 708 to rotate. At this time, the ball 708 can reduce the friction between the stabilizing plate 4 and the operation box 6. By setting the adjusting device 7, through the mutual cooperation between the groove 701, the bidirectional lead screw 702, the screw block 703, the sliding groove 704, the sliding block 705, and the screw rod 706, the size of the 5 - pass welded pipe can be limited. It avoids the situation that in the actual welding process, due to the different sizes of the 5 - pass welded pipes, when welding 5 - pass welded pipes of different sizes, the distance between the two stabilizing plates 4 cannot be changed, resulting in deviation during welding by the laser welding machine and causing welding errors. It improves the adaptability of the laser welding machine and further improves the welding effect.
