In fact, the service life and productivity of the welding positioner depend not only on the weight and correct positioning of the workpiece, but also on the loaded current of the positioner. The positioner can directly rotate and tilt the workpiece to ensure that the whole weld can always be in a horizontal welding position, Moreover, the positioner itself is a high-energy and universal welding equipment that can realize circumferential seam welding. It can be combined with argon arc welding wire feeder, plasma welding machine, melting electrode gas protection welding machine and welding machine power supply to form an automatic welding system.
Moreover, the welding positioner can also rotate and tilt the workpiece, which is convenient to directly place the more complex structural parts at the level of the weld, or ship shaped position for welding. Therefore, the whole driving system of welding positioner can be divided into two aspects: 1. Overturning driving; 2. Swing drive. The overturning drive can be divided into two different forms: hydraulic and electric; The rotary drive is more common electric drive. The speed belongs to stepless adjustment, which can realize positive and negative steering.
If it is a large welding positioner or a welding positioner that requires a relatively small lifting range for the workbench, it is common to select hydraulic drive on the lifting and tilting device. The great advantage of hydraulic drive is that it is relatively easy to control. The structural characteristics can be divided into high speed regulation accuracy, very good reliable performance, and very stable welding.
