Welding positioner is not a direct operation device in the welding process, but it plays a vital role in the welding process, and many welding quality has been improved as a result. The welding roller frame is suitable for the welding of circular cylinders. The distance between the rollers can be adjusted according to the size of the cylinder. There are various specifications of the roller frame for users to choose from. The roller frame suitable for large tonnage weldments can be designed and manufactured instead. There are three types of adjustable roller racks: manual screw adjustment, manual bolt shift and electric skateboard shift. By adjusting the center distance of the rollers, it is suitable for different diameter cylinders.
The welding positioner is used to drag the workpiece to be welded, so that the welding seam to be welded moves to the ideal position for welding operation. Generally speaking, most manufacturers of welding manipulators, roller frames, welding systems and other welding equipment produce welding positioners; most manufacturers of welding robots produce welding positioners for robots.
The roller frame is a device that drives the cylindrical (or conical) weldment to rotate by means of the friction between the weldment and the driving roller. For example, when the fan is welded, the welding positioner solves many problems again in the welding process. Before using the welding positioner, the welding process of the fan is not only prone to structural deformation, which affects the overall quality of the product and the progress of welding production, but also the welding position is very unreasonable, which greatly increases the difficulty of the operator's operation, thereby increasing the incidence of welding defects. possibility. In addition, without the assistance of the welding positioner, the structure of the fan is difficult to lift and turn, and only the welding position of some welds can be changed, which cannot be fully optimized. In order to overcome these shortcomings, a welding positioner is developed, through which the fan can be reasonably rotated when welding the fan, and the welding machine can obtain a good welding position and viewing angle when the welding machine is fixed in situ, so as to realize the welding operation. And from the welding positioner itself, it can clamp the range of 3.5 meters on the flange structure of the welding positioner, which is more convenient and fast. By changing the radial elevation angle, the height of the welding operator's operating position can be properly adjusted, which is convenient for welding operations. In contrast, the welding positioner can mainly change the welding position. As long as the workpiece is welded on the annular rotating flange, through radial rotation, the welding position of the workpiece can be changed from vertical welding to flat welding or from flat welding. For vertical welding. The use of this welding positioner not only improves the welding position, but also greatly improves the welding quality rate.
