WRIST TO PROGRAM TORCH POSITIONING
Brushless motors, absolute encoders and planetary «zero backlash» gearings can turn and tilt the CNC torch handling wrist with extreme accuracy and repeatability, both for positioning and interpolated motion control.
The first and the second picture underneath show an example of a 2-axis wrist installed at the boom end of a manipulator, to provide resetting the torch at different angles.
A 2- axis robot wrist allows to turn the torch 0° to 180° to allow welding in both directions as well as tilting it 45° to perform longitudinal fillet welding, thus avoiding idle back strokes and manual setting of torch position.
Wrist payload allows carrying:
• A linear oscillator.
• An IG 2D tracking system.
• Two cameras installed ahead and downstream welding.
• A torch .
• A vertical slide with AVC function.
• A torch tilt axis.
TIG cold wire application, allowing to modify the torch tilt angle at each welding pass
