Schunk expanded its servo-electric two-finger parallel gripper of the PEH series to include sizes 30 and 50. This significantly expands the application spectrum for this universal long-stroke gripper, because with a maximum stroke of 100 millimeters per finger for the PEH 50, these grippers are now suitable for a large parts spectrum, extending from small components to large workpieces. The robust guides are designed for precise handling even at high loads and the gripping force can be adapted to the broad application spectrum – for the PEH 50 as high as 1400 N, with maximum finger lengths of up to 250 millimeters.
The PEH grippers are driven by a brushless servo motor, which transfers its power directly to the ball bearing drive spindle. The base jaws are moved by a driver on the spindle, while a kinematic unit synchronizes the movements of the two base jaws based on the rack and pinion principle, which ensures exact centric gripping with a repeat accuracy of 0.05 mm.
With the new SCHUK controller, the complete control and power electronics are already integrated in the grippers of the PEH series. This controller is used for the standardized control of almost all servo-electric components from the SCHUNK product line and enables very easy programming, pre-configuration and commissioning. Single commands can be combined to form complete tasks, and command libraries that are once created can also be used for other modules.
