Gripping device for use in handling robot for gripping e.g. cubic workpieces, has pivot axle selectively arranged in and external engagement with gear arrangement, where simultaneously rotational direction of another axle is reversible

摘要

The device (10) has a gripping arm (11) with three gripping fingers (12-14) pviotably arranged at pivot jaws (30). Pivot axles (25-27) are arranged in equal angular distances relative to each other on a pitch circle diameter in a distance to a rotational axis (28) of the arm. An electric motor and a fluidic drive are coupled with the axles. The axles are coupled with each other by a gear arrangement (18) i.e. pinion gear (19). One the axles is selectively arranged in and external engagement with the gear arrangement, and simultaneously a rotational direction of the other axle is reversible.
