Abstract
A grasping device for handling equipment has clamping fingers (4) which are movable relative to one another and an actuating device (5) for the clamping fingers which consists of piston-in-cylinder units (9, 17) which are coaxially arranged one behind the other and coupled in force transmitting manner. These piston-in-cylinder units are energized in the same sense by the pressure medium. This space saving construction makes it possible to achieve high clamping forces for a given pressure of the pressure medium while maintaining compact external dimensions of the grasping device.
Claims16
Apparatus for handling equipment comprising a clamping device having at least two clamping fingers which are movable relative to one another and mounted on a housing;
- and a clamping finger actuating device provided in the housing and having at least first and second piston-in-cylinder units coaxially disposed behind one another, coupled together in force transmitting relationship, and simultaneously energisable with pressure fluid in the same sense.
A grasping apparatus for handling equipment comprising a clamping device having at least first and second clamping fingers which are movable relative to one another and mounted on a housing;
- and a clamping finger actuating device provided in the housing and having at least first and second piston-in-cylinder units coaxially disposed behind one another, coupled together in force transmitting relationship, and energisable with pressure fluid in the same sense, the cylinders of said first and second piston-in-cylinder units being separated from each other by a transverse cylinder-partitioning wall, the piston of the second piston-in-cylinder unit including a central projection sealingly passing through the transverse cylinder partitioning wall and contacting the piston of the first piston-in-cylinder unit, which is disposed adjacent the clamping fingers, with the piston projection defining the force transmitting relationship.
