Description

Technical Field

[0001] The utility model relates to the technical field of clamping and fixing mechanisms, in particular to a clamping and fixing mechanism for hot-rolled seamless steel pipes. Background Art

[0002] Seamless steel pipes are made of a whole piece of metal, and there are no seams on the surface. Hot-rolled seamless steel pipes require a clamping and fixing mechanism during the processing and transfer process. The prior art discloses a variety of clamping and fixing mechanisms for seamless steel pipes. For example, the Chinese utility model patent with publication number CN216540222U proposes a positioning tool for hot-rolled seamless steel pipe production. The positioning tool places the seamless steel pipe through a support block, and the motor drives the rotating shaft to rotate, and the gear rotates accordingly, thereby driving the first movable rod and the second movable rod meshing with the gear to move in the fixed block. The mounting block moves with the movement of the first movable rod and the second movable rod, and the movable block moves in the movable groove, driving the first connecting rod and the second connecting rod to change the angle in the fixed seat, and then driving the connecting plate to move in the direction of the clamping mechanism, prompting the clamping mechanism to clamp the seamless steel pipe.

[0003] However, the above positioning fixture cannot move the hot-rolled seamless steel pipe on the support block laterally. After the two slide bars cooperate with the support block to clamp the hot-rolled seamless steel pipe, due to the lack of a locking structure for the slide bars, the clamping of the hot-rolled seamless steel pipe is easily loosened, resulting in poor reliability. Utility Model Content
