Description

Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, and more specifically, to a clamping mechanism for precision welded pipe processing. Background Art

[0002] Welded steel pipes, also known as welded tubes, are steel pipes made by welding steel plates or strips after being curled. When welding a welded pipe, the curled welded pipe is supported by a clamping frame, and workers weld several points of the welded pipe to prevent it from loosening. However, the clamping frame is not convenient for clamping welded pipes of different sizes, which affects the welding of the welded pipe.

[0003] For example, as disclosed in the publication (announcement) number: CN221065065U, a clamping frame for welded pipe welding includes a support frame and a connecting plate. The connecting plate is welded to the inner side of the support frame. An adjusting mechanism and a clamping mechanism are arranged on the inner side of the support frame. The clamping mechanism includes a base, a support rod, a clamping piece, a second threaded rod, and a pressing piece. The support rod is welded to one side of the top of the base. One end of the clamping piece is slidably connected to the outer surface of the support rod, and the other end of the clamping piece is threadedly connected to the outer surface of the second threaded rod. The second threaded rod is welded to one side of the top of the base. The pressing piece is welded to the inner side of the clamping piece. An arc-shaped notch is formed in the top of the base, and small holes are formed on both sides of the base. The adjusting mechanism includes a driving motor, a first threaded rod, and a support plate. The driving motor is arranged on one side of the support frame.

At the same time, it cannot drive the welded pipe to rotate, so it cannot be adjusted correspondingly according to different usage requirements. Therefore, a clamping mechanism for precision welded pipe processing needs to be proposed. Content of the Utility Model
