Abstract

A device creates a clamping between clamping surfaces (24, 26) facing each other and forming a frictional engagement between each other, on a stationary body (2) and a body (4) that can be moved relative the stationary body (2), in particular in the form of a rotary indexing table. A power drive (40) that can be actuated by a fluid pressure is provided for creating a clamping force effective between the clamping surfaces (24, 26). For forming pairs of clamping surfaces (24, 26) interacting with each other a pack of lamellas lying upon each other is provided, formed from stationary disks (24) connected to the stationary body (2) and from movable disks (26) connected to the movable body (4). The power drive (40) can be used to apply a pressing force to the disks (24, 26) in a clamping area (42).

Dependent claims

A rotary indexing table, comprising:

a stationary body;
a movable body movable relative to the stationary body;
a clamp selectively forming a frictional engagement between the stationary body and the movable body restraining relative movement between the stationary body and the movable body and releasing the frictional engagement for relative movement of the stationary body and the movable body by a pressure force selectively and alternatively applying and releasing the frictional engagement, the clamp including a pack of lamellas upon each other, the pack of lamellas including stationary disks connected to the stationary body and movable disks connected to the movable body;
a power drive applying the pressure force to the stationary and movable disks in a clamping area of the clamp, the power drive being a part of a clamp device body;
and
a clamping cartridge formed of the stationary body, the movable body, the pack of lamellas and lamella bodies supporting the stationary disks and the movable disks into an interchangeable and replaceable unit with the stationary body being an outer ring adjoining an outer circumference of the clamping cartridge and with the movable body being an inner ring of the clamping cartridge rotatable relative to the outer ring, an upper surface of the inner ring forming a rotating interface capable of attaching objects during use of the indexing table.
