Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to automatic welding equipment for compressor casing pipes. Background Art

[0002] The existing compressor housing and pipe welding is usually performed by a welding gun to weld a compressor housing alone, which is inefficient. For example, a pipe connection welding device for an air-conditioning compressor housing disclosed in Chinese Patent No. ZL202321977316.7 includes a welding module and a pushing module. The welding module includes a table frame, a reinforcement plate installed on the rear side of the table frame, a first motor connected between the table frame and the reinforcement plate, a turntable connected to the output shaft of the first motor, a plurality of arc-shaped clamping plates embedded in the turntable, and a plurality of elastic metal plates embedded in the turntable. In the utility model, the first motor rotates with the turntable. When the object to be welded moves to the position of the welding equipment, the welding equipment welds the air-conditioning compressor housing and the pipe body, and then the turntable continues to rotate to ensure the welding efficiency. After that, when the successfully welded air-conditioning compressor housing and the pipe body move to the front side of the cylinder, the cylinder pushes the finished product out of the arc-shaped clamping plate. The welding operation and the unloading operation cooperate well, and the two are implemented quickly and efficiently, which improves the welding efficiency.
