Description

Technical Field

[0001] The utility model relates to the field of steel pipe polishing devices, in particular to a steel pipe weld auxiliary polishing device. Background Art

[0002] The steel pipe weld auxiliary polishing device is a device specially designed for polishing the welded parts of steel pipes to improve the appearance and quality of the welded parts.

[0003] Common steel pipe polishing devices only include polishing components, which can polish steel pipes, but lack detection components and cannot detect the flatness of the polished surface of the steel pipe. As a result, the polished surface of the polished steel pipe may not be flat enough and needs to be re-polished, thereby reducing processing efficiency.

[0004] Therefore, in view of the fact that the above-mentioned steel pipe polishing device lacks detection components and is unable to detect the flatness of the polished surface of the steel pipe, an auxiliary polishing device for steel pipe welds can be designed. Through the circumferential detector on the outer wall of the limit ring, circumferential detection can be performed on the weld of the rotating steel pipe. When the gap between the circumferential data of the polished surface and the steel pipe exceeds the set value, the first electric telescopic rod will drive the steel pipe to move to the right, thereby polishing the steel pipe again until it passes the inspection, so as to improve the processing efficiency.

The movement of the first electric telescopic rod 11 will cause the two arc-shaped clamps 14 to move synchronously to the left with the steel pipe, so that the steel pipe is inserted into the inner side of the limit ring 65. At the same time, by restarting the first motor 8, the two arc-shaped clamps 14 can rotate with the steel pipe at a uniform speed. At the same time, the RA-120 circumference detector 66 on the outer wall of the limit ring 65 can perform circumference detection on the rotating steel pipe welding point.
