Product overview
4.1
Function
–
Alternating pressurisation of the supply ports causes a piston in the gripper to
move (double-acting).
–
A gripper with integrated spring return is used to exert the gripper force. When
exhausting the single-acting gripper: the spring return moves the gripper jaws
to the initial position.
–
N/O contact: NO (normally open)
–
N/C contact: NC (normally closed)
–
The piston movement is transmitted mechanically to the gripper jaws. Gripper
fingers are fastened to the gripper jaws. Closing or opening the gripper fingers
clamps the payload to the outer contour (external gripping) or the inner contour
(internal gripping).
–
The gripping force is adjusted by external regulation of the operating pressure.
–
The gripper has integrated fixed flow restrictors. If the max. gripper finger
weights and the max. gripper finger lengths are in compliance, an external flow
control is not required.
