Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary equipment, in particular to an arc welding flipping mechanism. Background Art

[0002] Some pipelines need to connect two or more pipelines to each other under different usage requirements, and the connection of metal pipelines is generally welded, which can increase the strength of the connection between the pipelines and ensure that the pipelines are still stable and reliable under extreme environments such as high pressure and high temperature;

[0003] Since the pipe is a cylindrical structure, when welding the two pipes together, the pipes need to be clamped and fixed, such as the Chinese utility model patent disclosed by publication number CN209986475U: a pipe welding clamp, which prevents the pipe from moving during welding by cooperating with a fixing block and a pressing block to ensure welding quality, and enables the bracket to be opened and closed by the lock and hinge structure of the bracket to facilitate the placement and removal of the pipe. However, since the connecting section of the two pipes is annular, when welding the two pipes together, an annular welding operation needs to be performed along the longitudinal section of the pipe. After the pipe is clamped and fixed, the application cannot achieve a stable and uniform rotation of the pipe, so that the clamping mechanism needs to be loosened after a certain welding process, and the pipe needs to be manually rotated to achieve welding of other unwelded areas, which makes the overall welding process complicated and increases the welding time.
