[0026] The lifting frame 1 has brackets 101 installed on both sides. The brackets 101 are internally connected with reinforcing ribs. The brackets 101 and the reinforcing ribs keep the lifting frame 1 stable and perform rotary welding processing.

[0027] The gantry frame 2 is slidably connected to the lifting frame 1, and the gantry frame 2 and the lifting frame 1 are connected by gears and racks. The gantry frame 2 drives the laser welding machine 3 to move laterally above the lifting frame 1, thereby adjusting the position of the welding head 301.

[0028] In fact, the lower end of the gantry frame 2 is equipped with a connecting lug 201, and the rear end of the laser welding machine 3 is fixedly connected to a positioning frame 304. The positioning frame 304 is hinged to the connecting lug 201, and the upper end of the positioning frame 304 is hinged to a support frame 305. The upper end of the support frame 305 is connected to the auxiliary frame 202 by fixing screws. In use, the upper end of the laser welding machine 3 is connected through the connecting lug 201. The laser welding machine 3 is limited by the positioning frame 304 and the support frame 305 to maintain rotational stability and adapt to long-term work.

[0029] Furthermore, an auxiliary frame 202 is bolted to the rear end of the gantry frame 2. An electric cylinder 303 is installed between the auxiliary frame 202 and the positioning frame 304. The two ends of the electric cylinder 303 are hinged to the auxiliary frame 202 and the positioning frame 304, respectively. By installing the electric cylinder 303 between the gantry frame 2 and the laser welding machine 3, the extension and retraction of the electric cylinder 303 adjusts the welding angle of the welding head 301 at the lower end of the laser welding machine 3. The structure is simple and easy to operate. Combined with the welding fixture 5, it can achieve rapid adjustment and adaptation to work.

[0030] Specifically, this rotary pressure vessel welding device adopts a combination of welding fixture 5 and lifting frame 1.

The structure is simple and adaptable to different working environments. The pressure vessel 4 to be processed is placed on the welding fixture 5. The drive motor 506 drives the electric wheels 502 to rotate, and the electric wheels 502 drive the main body of the pressure vessel 4 to be processed to rotate. The pressure vessel 4 to be processed is welded after rotation. An electric cylinder 303 is installed between the gantry frame 2 and the laser welding machine 3. The electric cylinder 303 extends and retracts to adjust the welding angle of the welding head 301 at the lower end of the laser welding machine 3. The structure is simple and easy to operate. Combined with the welding fixture 5, it can be quickly adjusted and adapted to the work.
