Welding roller frame is a kind of welding auxiliary equipment, double drive roller frame belongs to one of them, which is often used in the welding work of inner and outer circular seams and inner and outer longitudinal seams of cylindrical workpiece, to better stabilize the workpiece, and to complete the accurate displacement of the weldment efficiently.

The double drive roller frame is composed of base, driving roller, driven roller, bracket, driving device, driving device, etc. The driving device drives the driving roller, and uses the friction between the driving roller and the cylindrical workpiece to drive the workpiece to rotate to realize the displacement, so as to realize the horizontal position welding of the inner and outer circumferential seams and the inner and outer longitudinal seams of the workpiece.

The double drive roller frame matched with automatic welding equipment can realize automatic welding, greatly improve the weld quality, reduce labor intensity and improve work efficiency. Welding roller frame can also be used for manual welding or as equipment for detecting and assembling cylinder workpiece.

According to the size of the workpiece, the double drive roller carriage can adjust the swing angle of the roller automatically, so as to meet the different welding requirements; at the same time, it adopts the double drive stable and variable frequency stepless speed regulation, which not only has strong driving ability, but also has high precision. In addition, it has manual control box to complete forward rotation, reverse rotation, emergency stop, speed adjustment and other functions
