Automatic surfacing equipment

The utility model discloses automatic surfacing equipment which can effectively solve the problem that the equipment cannot be matched with various surfacing pipelines in pipe diameter. Comprising a mounting platform; the surfacing welding machine is arranged on the mounting platform in a sliding manner; the placing frame is arranged on the mounting platform; the placing frame comprises a frame plate, the front end face and the rear end face of the frame plate are inclined faces, air cylinders are arranged on the inclined faces, and rotating rollers are arranged at the piston ends of the air cylinders. The device has the beneficial effects that when the air cylinder is started to push the piston rod, the linear distance between the front and rear rotating rollers is reduced, and pipelines with small diameters can be placed; when the air cylinder is started to contract the piston rod, the linear distance between the front and rear rotating rollers is increased, and a pipeline with a large diameter can be place
