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).

Abstract: A tool turret has a housing (1), a turret head (2) rotatable relative to the housing (1) by a drive. Two toothed rims (4, 9?) are arranged coaxial to the rotational axis of the turret head (2). One rim (4) is connected fixedly to the turret head (2). The other rim (9?) is connected fixedly to the housing (1). A locking part (24) can be moved axially relative to the housing (1) and to the turret head (2), with the toothing system (24?) oriented towards the two toothed rims (4, 9?). In the locked position, the locking part is in engagement with the rims as a positively locking connection. A pressure fluid control actuates the movement of the locking part (24). An additional frictionally locking connection (73) is established between the housing (1) and the turret head (2) by a frictionally locking device (67).

Abstract: A tool turret having a housing (1), a turret head (2) which can be rotated relative to the housing (1) by means of a drive, two toothed rims (4, 9?) which are arranged coaxially with respect to the rotational axis of the turret head (2) and of which the one (4) is connected fixedly to the turret head (2) so as to rotate with it and the other (9?) is connected fixedly to the housing (1) so as to rotate with it, a locking part (24) which can be moved axially relative to the housing (1) and to the turret head (2), with the toothing system (24?) which is oriented towards the two toothed rims (4, 9?) and, in its locked position, is in engagement with the latter as a positively locking connection, and a pressure fluid control device for actuating the movement of the locking part (24), is characterized in that, in the locked state, an additional frictionally locking connection (73) is established between the housing (1) and the turret head (2) by means of a frictionally locking device (67), in addition to the positi

Abstract: A tool revolver, in particular for a machine tool, includes a tool disk (1) rotatable about a revolver axis and provided with a plurality of tool stations distributed along the disk circumference and movable to an operation position by the disk (1) rotation. At least one part of the tool stations (13) has a reception area (25) for receiving a tool holder (3). A fixing device is used for fixing a corresponding tool holder (3) at a defined position in the reception area (25). The interaction between an elastic adjusting body (31) protruding perpendicularly to the reception area (25) and used in the form of an orientation element for positioning and adjusting surfaces (41, 43) deepened into a base surface (7) of the tool holder (3) enables the tool holder to take an adjustment position when a screw fitting is fastened.

Abstract: A tool turret has a housing, a head connected nonrotatably with the housing, and a tool face arranged concentrically to and encompassing the head. The tool face is rotatable around the housing longitudinal axis relative to the housing and head, and is lockable in predetermined angular positions with the housing. A receiving and holding area for a drivable tool is provided in the tool face. A head shaft extends radially in the head relative to its central longitudinal axis. The head shaft can be driven through a miter-wheel gearing and a transmission shaft extending in the rotary axis of the tool face by a motor. A clutch is movable in a longitudinal direction along the head shaft axis relative to the driving shaft of a tool found in the work position, to join the head shaft and the tool shaft.
