Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding equipment, in particular to a welding operation platform capable of automatically adjusting welding position. BACKGROUND

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics through heating, high temperature or high pressure. Welding is also an important process in pipe processing, and the pipe welding machine is a common device in pipe welding process.

[0003] According to the search, the utility model patent with publication number CN218745381U discloses an automatic soldering machine capable of adjusting welding position. By setting the dust storage box, dust filter screen, main motor, fan blade and dust collection head, the main motor drives the fan blade to rotate during use, forming suction force. The soldering fumes generated during soldering are sucked into the shaping hose by the dust collection head, and finally reach the dust storage box. The metal dust in the soldering fumes is filtered by the dust filter screen, and finally stored in the dust storage box. The exhaust air does not contain metal dust, protecting the health of the workers.

[0004] In the above technical solution, the welding gun slides on the cross beam to adjust the welding position. However, when welding pipes, the pipes are usually placed below the welding frame, and the welding gun is used to weld the welding position. However, after welding is completed, the pipes need to be manually loaded and moved out after welding. This method is time-consuming and labor-intensive, and the degree of automation is not high. In addition, when the pipes enter the welding position of the welding frame, the welding ends of the two pipes need to be manually aligned, and the welding position of the pipes needs to be adjusted, which is inconvenient for the welding gun to weld the position.

The surface of the rotating push block corresponds to the outer wall surfaces of the two pipes. The two ends of the pipe are preliminarily limited by the cooperation of the limiting block and the rotating push block, ensuring the stability of the pipe during welding. When the ends of the two pipes are welded, the corresponding rotating push blocks are driven to rotate by the two rotating cylinders.
