Abstract
An apparatus for polishing a butt weld includes a machine frame; a polishing mechanism, including a rotating arm, a supporting column rotatably mounted on the rotating arm, and a polishing roll rotatably mounted on the supporting column in a circumferential direction of the polishing roll; an angle limiting assembly, movably mounted on the rotating arm, the angle limiting assembly limiting an angle at which an outer side end of the supporting column swings upward; a roll driving part, mounted on the rotating arm. The roll driving part is in transmission connection with the polishing roll and drives the polishing roll to rotate on the supporting column in the circumferential direction of the polishing roll. An arm driving part is mounted on a fixed frame, the rotating arm being mounted on the arm driving part, and the arm driving part drives the rotating arm to rotate in a circumferential direction.
