Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, and specifically relates to a multi-size fixture for steel pipe processing. Background Technology

[0002] A clamp is a device used to fix a workpiece during the mechanical manufacturing process. In the production and processing of steel pipes, clamps are needed to fix them and prevent them from shaking during processing. However, most commonly used clamps can only hold and fix steel pipes of a fixed size. Since steel pipes come in various diameters, different clamps are needed when processing steel pipes of different diameters, resulting in a limited range of applicability and poor performance.

[0003] In view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. In the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, as well as after much ingenuity and experimentation, this utility model was created, and a multi-size clamp for steel pipe processing is provided.

[0010] By adopting the above solution, the V-shaped clamp can be raised and lowered by the screw, which can adapt to the processing needs of different steel pipe sizes while ensuring its stability.

[0011] As a preferred embodiment of a multi-size clamp for steel pipe processing, the ring is composed of two half-rings fixed together, and a first fastener is fitted between the two half-rings, and the two half-rings are fixed together by the first fastener.

[0012] As a preferred embodiment of a multi-size clamp for steel pipe processing, a second fastener is provided on the semi-ring, and the semi-ring is fixedly engaged with the welding column by the second fastener.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are: the multi-size clamp for steel pipe processing proposed by this utility model has a simple structure and can achieve clamping and fixing of steel pipes.

[0016] The process of the screw driving the V-shaped clamp to move up and down can adjust the distance between it and the V-shaped tube seat, thereby adapting to the processing needs of different steel pipe sizes. At the same time, the clamping action of the V-shaped clamp and the V-shaped tube seat ensures its stability.
