Welding roller frame

Welding roller is a welding auxiliary equipment, in particular to a welding roller frame, commonly used in the cylindrical workpiece inner and outer ring and inner and outer longitudinal seam welding. Includes a base, a driving roller, a driven roller, frame, transmission device, power device. The transmission device to drive the active wheel, using the active roller and the friction between the cylindrical workpiece drives the rotation of the workpiece to achieve change, the horizontal position of the workpiece can be both inside and outside the ring and inner and outer longitudinal seam welding, automatic welding equipment can realize automatic welding, can greatly improve the weld quality, reduce labor intensity, improve work efficiency. Welding roller frame can also be combined with manual welding or as detection, assembly of cylinder workpiece equipment.
