If the workpiece is fixed all the time during welding, the operation will be very difficult. The existing technology is to place the workpiece on the roller rack, and drive the workpiece to rotate by the rotation of the roller, so that the unwelded part is always located at the bottom of the workpiece, avoiding vertical welding and overhead welding, and greatly reducing the construction difficulty. However, the weight of large cylindrical workpieces is very large. When large cylindrical workpieces roll, vibration is likely to occur. The existing roller rack has poor shock-absorbing effect, which is not only easy to cause a large degree of wear on the roller rack, but also easy to cause deformation of the roller rack. The use effect is not ideal, and the existing roller rack is difficult to adapt to workpieces of different sizes, and the roller and the workpiece cannot fit together, and it is difficult to adapt to workpieces of different sizes.
