Abstract
A fluid power operate gripper has a housing, in which a drive space is located, which contains at least two drive pistons connected or able to be connected with a respective gripping element. The drive pistons divide up the drive space into a plurality of actuating chambers, which are subject to an actuating fluid under the control of control means in a controlled mutually matching manner. Since the drive pistons are not mechanically coupled kinematically variable operation is made possible in this manner.
Claims20
A fluid operated gripper comprising a housing, in which a drive space is located, in which space at least two drive pistons are arranged in sequence, such pistons being respectively connected or being able to be connected with a gripping element, said pistons being able to be shifted and positioned in the direction of their sequence in relation to the housing and in relation to one another, said pistons dividing up the working space into two outer actuating chambers respectively only delimited by one drive piston and furthermore into at least one inner actuating chamber delimited simultaneously by directly following drive pistons, wherein in order to permit mutually independent movement the drive pistons are not mechanically kinematically ganged together, the individual actuating chambers being provided for mutually matching fluid action controlled by control means.
