Adaptive shape gripper DHEF

The adaptive shape gripper DHEF is a flexible gripper that can handle many different objects without the need to change grippers.

The gripper is best suited to handling small parts, for picking or for working in close proximity to humans, when precision and cycle times are not so important.

The gripper consists of a pneumatic drive and the inverting cap, which is connected to the piston rod at its tip. The cylinder motion pulls the cap tip inwards, allowing objects to be gripped during the inverting motion.

Two sensors can be mounted in T-slots on the side of the cylinder. They report the piston position and provide feedback on the gripping process.

The gripper also has an ISO interface for mounting on a robot.
