[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 5 In an embodiment of the present invention, a metal welding robot adjustment structure includes two guide rails 1, and the two guide rails 1 have sliding cavities on their surfaces close to each other, and the two guide rails 1 are connected by end covers 2 at the ends. One end of the end cover 2 is equipped with a horizontal moving mechanism extending into the sliding cavity, and the horizontal moving mechanism is used to drive the moving frame 4 to move in the horizontal direction. A top plate 5 is fixedly installed on the top of the moving frame 4, and a vertical moving mechanism extending to the inside of the moving frame 4 is installed on the top of the top plate 5. The vertical moving mechanism is used to drive the sliding frame 12 to move up and down, and an adjustment mechanism is installed on the sliding frame 12. The adjustment mechanism is used to drive the laser welding head 20 to rotate and adjust.

[0020] In this embodiment, when welding the plates, if the welding angle between the two metal plates changes, the vertical moving mechanism drives the sliding frame 12 to move up and down. When the sliding frame 12 moves to a preset position, the adjusting mechanism is activated, and the adjusting mechanism drives the laser welding head 20 to rotate until the welding nozzle of the laser welding head 20 is aligned with the welding point.

[0021] Then, the horizontal moving mechanism and the laser welding head 20 are started. The horizontal moving mechanism drives the laser welding head 20 to move horizontally through the moving frame 4, so that the two plates can be welded.

[0022] Please refer to Figure 1 and Figure 5The horizontal moving mechanism includes a forward and reverse motor 3 installed at one end of the guide rail 1 through a mounting bracket and a screw 21 rotatably connected between the two end covers 2. One end of the screw 21 passes through the outside of one end cover 2. The output end of the forward and reverse motor 3 is fixedly connected to one end of the screw 21 through a coupling. The outer wall of the screw 21 is threadedly connected to a sliding block 11. The sliding block 11 slides horizontally in the sliding cavity. The two ends of the sliding block 11 are fixedly connected to the sides of the two moving frames 4 that are close to each other.

[0023] In this embodiment: by starting the No. 1 forward and reverse motor 3, the No. 1 forward and reverse motor 3 drives the No. 1 screw 21 to rotate. At this time, the sliding block 11 threadedly connected to the outer wall of the No. 1 screw 21 slides horizontally along the sliding cavity. At this time, the sliding block 11 drives the movable frame 4 to move synchronously, and the moving movable frame 4 drives the adjustment mechanism, the vertical moving mechanism and the laser welding head 20 to move synchronously.

[0024] Please refer to Figure 1 and Figure 3 The vertical moving mechanism includes a vertical groove 9 which is opened on the outside of the moving frame 4 and recessed inward. A No. 2 screw 10 is rotatably installed on the bottom end of the inner wall of the vertical groove 9. The top of the No. 2 screw 10 passes through the top of the top plate 5. The No. 2 screw 10 is rotatably connected to the top plate 5. The tops of the two top plates 5 are coaxially connected with a transmission wheel 7. The two transmission wheels 7 are connected by a transmission belt 8. The top of the top plate 5 is installed with a No. 2 forward and reverse motor 6 through a connecting bracket. The output shaft of the No. 2 forward and reverse motor 6 is fixedly connected to the top center of one transmission wheel 7.

[0025] In this embodiment: when adjusting the height of the laser welding head 20, by starting the No. 2 forward and reverse motor 6, the No. 2 forward and reverse motor 6 drives the transmission wheel 7 connected to it to rotate, and the transmission wheel 7 drives another transmission wheel 7 to rotate synchronously through the transmission belt 8. The two rotating transmission wheels 7 respectively drive the No. 2 screw 10 connected to the bottom end to rotate. At this time, the sliding frame 12, which is slidingly connected to the vertical slot 9 and threadedly connected to the No. 2 screw 10, moves up and down along the vertical slot 9 to adjust the height of the laser welding head 20, and the adjusting mechanism moves synchronously with the sliding frame 12.

[0026] Please refer to Figure 2 、 Figure 3 and Figure 4The adjusting mechanism includes a protruding plate 13 integrally formed at one end of the sliding frame 12, and a No. 1 electric push cylinder 14 is installed on one side of the top of the protruding plate 13. The output end of the No. 1 electric push cylinder 14 passes through the bottom of the protruding plate 13 and is connected to an L-shaped frame 15. The top of the L-shaped frame 15 is fixedly connected to a rack 16, and the outer periphery of the rack 16 is engaged with a gear 17. The adjusting mechanism includes a rotating block 18 rotatably connected to one side of the sliding frame 12, and the rotating block 18 is connected to the gear 17 through a synchronous shaft. The synchronous shaft is rotatably connected to the sliding frame 12, and a mounting plane is formed on the outer periphery of the rotating block 18. A No. 2 electric push cylinder 19 is fixedly connected to the mounting plane. The output shaft of the No. 2 electric push cylinder 19 passes through the rotating block 18 and is fixedly connected to one end of the outer shell of the laser welding head 20.

[0027] In this embodiment: when adjusting the angle of the laser welding head 20, by starting the No. 1 electric push cylinder 14, the output shaft of the No. 1 electric push cylinder 14 moves upward or downward, and the L-shaped frame 15 connected to the No. 1 electric push cylinder 14 moves synchronously. The moving L-shaped frame 15 drives the rack 16 to move upward or downward, and the rack 16 drives the gear 17 to rotate when moving. The rotating gear 17 drives the rotating block 18 to rotate through the synchronous shaft. At the same time, the No. 2 electric push cylinder 19 installed on the rotating block 18 rotates synchronously, and the No. 2 electric push cylinder 19 drives the laser welding head 20 to rotate. Since the laser welding head 20 performs a circular motion during the above action, the nozzle of the laser welding head 20 not only changes its angle, but also changes its distance from the welded plate. At this time, the No. 2 electric push cylinder 19 is started to operate, and the No. 2 electric push cylinder 19 drives the laser welding head 20 to move along the extension line of its angle, and adjusts the distance between the nozzle of the laser welding head 20 and the welding line to a suitable position.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
