This Turning roller bed is designed on basis of our conventional welding rotator, for special requirements of motor rotor rotation. As the rotor has a special shape that has a bigger diameter in middle and a much smaller diameter at two ends, the roller bed is revised to increase the center height, the two motors are from ABB, speed is controlled by Schneider inverter, which provide a wide range and smooth speed variation.

The function of the welding roller frame is mainly to provide a stable and adjustable support platform for welding operations. Specifically, it has the following main functions:
1. **Support and positioning**: The welding roller frame can stably support weldments of various specifications and weights to ensure that they remain stable and do not shake during the welding process. At the same time, the roller frame can accurately position the weldment by adjusting the position and spacing of the rollers to facilitate welding operations.
2. **Rotation and movement**: The roller frame is usually designed with rollers and transmission mechanisms, which can easily rotate the weldment to achieve the ideal welding position during the welding process. Some advanced roller frames also have a mobile function, which can adjust the position of the roller frame as needed to improve the flexibility and efficiency of welding.
3. **Adapt to different specifications**: The adjustable roller frame can adapt to weldments of different diameters, lengths and weights. By adjusting the center distance and number of rollers, it can ensure that the weldment is placed stably on the roller frame, providing stable support for welding operations.
4. **Cooperation with automatic welding equipment**: The adjustable roller frame can be used in conjunction with automatic welding equipment to achieve automated welding. During the welding process, the roller rack can accurately control the rotation speed and position of the weldment, and work in conjunction with the automatic welding equipment to improve welding efficiency and quality.
5. **Reduce workpiece damage**: The design of the roller rack takes into account the protection of the workpiece, and usually uses soft materials such as rubber to wrap the roller to reduce damage to the workpiece surface. At the same time, the roller rack can also adjust the pressure of the roller according to the material and weight of the workpiece to avoid deformation or damage to the workpiece during welding.
In summary, the welding roller rack plays a vital role in the welding process. It can provide a stable and adjustable support platform for welding operations, improve welding efficiency and quality, reduce labor intensity, and reduce workpiece damage.
