一种钢管焊接用自适应夹持装置
By combining an electric push rod and a movable roller, the problem of traditional clamping devices being unable to adapt to steel pipes of different diameters is solved. This enables automatic adjustment of the clamping distance and stable rotation of the steel pipe, improving welding efficiency and quality and preventing damage to the steel pipe.

AI Technical Summary
Traditional steel pipe welding clamping devices cannot adapt to the clamping requirements of steel pipes of different diameters, requiring frequent adjustments or replacements of clamps, resulting in low welding efficiency and easily causing damage to the surface of the steel pipe and uneven welding quality.
The movable roller structure driven by an electric push rod, together with an auxiliary rotating component, enables automatic adjustment of the clamping gap and stable rotation of the steel pipe. The slider and chute guide ensure stable movement trajectory, and the auxiliary guide roller supports the rotation of the steel pipe, reducing friction damage.
It improves welding efficiency and quality, avoids damage to the steel pipe surface, simplifies the operation process, and enhances adaptability to steel pipes of different diameters and clamping accuracy.
