Abstract
A fluid operated gripper which possesses a gripper device housing resembling a hollow body and on which a bearing body is secured. On the bearing body at least two relatively moving gripper device jaw carriers are movably mounted in a slot arrangement. A drive piston runs in a piston chamber. The bearing body is designed in the form of an insert body, which is seated like a cartridge in a receiving chamber arranged in an axial extension of the piston chamber. The slot arrangement is overlapped to the side externally by the housing wall, which delimits the receiving chamber, for at least part of its length.
Claims26
A fluid operated gripper device comprising:
- a gripper housing having a hollow body defined by a wall,
- an insert body being secured to the housing, the insert body having a slot, a portion of which extends to the housing wall when the insert body is secured within the gripper housing,
- at least two gripper device jaw carriers being movably mounted to the insert body in the slot, and the insert body forming a bearing member for supporting the gripper jaw devices, the carriers being moveable between an open position and a closed position,
- an actuating element shiftable between two positions for causing movement of the gripper jaw carriers, wherein a shift of said actuating element in at least one direction being caused by operation of a piston running in a piston chamber,
- the insert body being seatable within a receiving chamber of said housing which axially extends from the piston chamber, the insert body including an axial recess therein aligned with the piston chamber for receiving and guiding the actuating element into engagement with the gripper device jaw carriers.
A fluid operated gripper device comprising:
- a gripper housing having a hollow body on which a bearing member is secured, the bearing member having a slot opening to a housing wall when said bearing member is inserted within said gripper housing,
- at least two gripper device jaw carriers being movably mounted in the slot, the carriers being moveable between an open position and a closed position,
- an actuating element shiftable between two positions for moving the gripper jaw carriers, wherein a shift of said actuating element in at least one direction being caused by operation of a piston running in a piston chamber,
- wherein the bearing member includes an insert body seatable within a receiving chamber of said housing which axially extends from the piston chamber, the insert body including detent projections extending therefrom, and
- wherein a portion of the housing wall delimiting the receiving chamber possesses detent recesses into which the detent projections of the insert body engage thereby locating the insert body in the receiving chamber.
A fluid operated gripper device comprising:
- a housing having a receiving chamber;
- an insert body having a portion secured within the receiving chamber, the insert body having a slot and having an axially extending recess therein;
- at least two gripper device jaw carriers moveably mounted to the insert body in the slot, the at least two jaw carriers being movable between an open position and a closed position;
- and
- an actuating element disposed in the housing and being translatable under fluid force between a first and second position for causing movement of the jaw carriers between the open and closed positions, the actuating element extending into the insert body recess and being guided by the insert body into engagement with the jaw carriers.
