Technical Field

[0001] The utility model relates to the technical field of water tank welding equipment, in particular to a telescopic, adaptable, self-positioning, automatic welding system. Background Art

[0002] In the existing refrigeration industry, during the cooling process, it is usually necessary to continuously supply water to the heat source through the water tank to complete the cooling work. Therefore, the processing requirements of the water tank are extremely high. For the welding work of conventional large water tanks, the welded water tanks are placed on the fixture, and then the staff weld them one by one with a handheld welding gun. Due to the large size of the water tank, the conventional welding fixture structure is not universal, the welding working range is limited, and the working method of welding one by one with a handheld welding gun is low in welding efficiency and cannot meet the welding production and processing of large quantities of water tanks.

[0003] Currently, Chinese patent authorization publication number CN215316528U discloses a feeding device for a universal agricultural water tank welding machine. This device relates to the field of agricultural water tank welding technology and aims to address the problem of existing welding machines lacking a feeding mechanism, forcing workers to manually feed the water tanks, reducing overall welding efficiency. The device comprises a workbench, a carrier, a water tank to be welded, a welding limit clamp, a welding device, and a feeding mechanism. The carrier is mounted on the workbench, the welding limit clamps are symmetrically arranged on the workbench, and the carrier and the welding limit clamps are connected by a support plate. The water tank to be welded is mounted on the carrier.

[0004] Although the feeding device of this universal agricultural machine water tank welding machine can realize the feeding and fixing of the water tank, the water tank is difficult to flip over when the device is in use. In the existing water tank welding, manual flipping is usually adopted, resulting in slow welding efficiency, large deformation of the water tank surface, and unsafe manual flipping of the workpiece.
