[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Combination Figure 1 and Figure 3 The table-top flip-type laser welding machine shown in the figure comprises a support structure 1, which supports and stabilizes the entire laser welding machine. A bed structure 2 is arranged above the support structure 1, and a beam structure 3 is slidably connected to the bed structure 2. A welding head 4 is slidably connected to the beam structure 3 above the beam structure 3. The beam structure 3 comprises a beam 31, and a rectangular groove 32 is provided inside the beam 31, and a screw rod 33 is provided inside the rectangular groove 32. A first motor 34 is arranged above the beam 31, and the first motor 34 is connected to the screw rod 33. A sliding beam 35 is vertically sleeved on the outer wall of the beam 31, and a thread meshing with the screw rod 33 is provided inside the sliding beam 35. The lower end of the beam 31 is slidably connected through a slide block provided on the upper surface of the bed structure 2. When the first motor 34 is driven, the screw rod 33 starts to rotate, and the sliding beam 35 drives the welding head 4 on the sliding beam 35 to move to a specified position through the mutual cooperation between the screw rod 33 and the thread to weld the workpiece. The table structure 5 and the bed structure 2 are fixedly provided with placement plates 6 on both sides above the table structure 5. The flip table structure 5 includes a second motor 51. The driving end of the second motor 51 is connected to a rotating shaft 52. The end of the rotating shaft 52 is rotatably connected to the inner wall of the placement plate 6. A welding table 53 is sleeved on the rotating shaft 52. Electric telescopic rods 54 are provided at both ends below the welding table 53. The head end of the electric telescopic rod 54 is connected to a fixed block 55. The fixed block 55 is fixedly connected to the inner wall of the placement plate 6. The end of the electric telescopic rod 54 cooperates with the card slot provided on the inner wall of the bed structure 2 for movably connection. The bed structure 2 below the welding table 53 is set to be empty, which can facilitate the flipping of the welding table 53. When the welding table 53 is damaged, the second motor 51 drives the rotating shaft 52. The rotating shaft 52 rotates and drives the welding table 53 to flip. The electric telescopic rod 54 retracts during flipping. When the welding table 53 is flipped 180 degrees, the electric telescopic rod 54 extends out and engages with the card slot to support the welding table 53.

[0025] Combination Figure 1 and Figure 2As shown, the inner wall of the placement plate 6 is fixed with a stabilizing device 7, which includes an arc-shaped fixing structure 71 and a baffle fixing structure 72.

An arc-shaped clamp 712 is provided between the piston ends of the first cylinder 711. A baffle groove 713 is provided on the top of the arc-shaped clamp 712. A slot 714 matching the baffle groove 713 is provided on the bottom of the arc-shaped clamp 712. When a pipe-like workpiece needs to be welded, the workpiece is placed on the welding table 53. At this time, the first cylinder 711 drives the arc-shaped frame 712 to move toward the workpiece through the internal piston, and the arc-shaped clamp 712 clamps and fixes the welding workpiece to prevent the position from shifting during welding and causing the weld to be too large. The baffle fixing structure 72 includes a cylinder fixing frame 721, and the cylinder fixing frame 721 is fixedly connected to the outer diameter surface of the arc clamp 712. A second cylinder 722 is provided above the cylinder fixing frame 721, and a baffle 723 is provided below the second cylinder 722. Both ends of the baffle 723 are provided with slide grooves 724.

When the baffle 723 is engaged with the slot 714, the first cylinder 711 acts at the same time to squeeze and fix the welding workpiece. By setting the stabilizing device 7, welding workpieces of different shapes can be fixed separately to prevent welding dislocation and improve welding quality.
