Abstract: A retaining device has clamping elements arranged on a housing that act as detachable locking elements and can be radially displaced when a pressure member located in the housing is axially displaced. First and second pressure media can act upon the pressure member in the axial direction and the second pressure medium acts upon the pressure member in the opposite direction to the first pressure medium. The retaining device is considerably simplified in that two chambers which follow each other in the axial direction are designed in the housing and separated by a membrane anchored on the housing and having axially movable sections. The pressure member is joined to the membrane and at least one of the chambers can be connected to a pressure medium source.

Abstract: Disclosed is a coupling device having two coupling parts and clamping means for releasably axially clamping both coupling parts. A plurality of circumferentially spaced non parallel grooves are cut into the surface of one of both coupling parts for having a reference in a plane perpendicular to the clamping direction. Pins project from the surface of the other coupling part each pin having two opposing parallel lateral surfaces for obtaining alignment of the grooves with the pins upon clamping. At least one of the lateral surfaces of each pin forms an angle with the associated flank of each groove upon axial alignment of the coupling parts. For improving the repeated precision of the positioning of one of the coupling parts relative to the other coupling part even upon high stress on one of the coupling parts in circumferential direction a clamping plate is provided between the lateral surface and the associated flank which is axially elastic and is mounted to one of the coupling parts.

Abstract: The subject of the invention is a retaining plate for a machine tool work piece, where the machine tool is equipped with a tool, e.g. an erosion wire, that can be moved in th z-direction of a work area, and where the work area is bounded by an xy-plane that is perpendicular to the z-axis, and with a work table whose work surface is in a specific position relative to the xy-plane and which is arranged in the direction of movement of the tool. In order to provide a holding mechanism that is particularly suitable for wire EDM-machines, and which allows for work piece transition any number of times without loss of alignment precision, a first plane section of the retaining plate with at least one opening for inserting the work piece, as well as retaining mechanisms for the work piece are provided, as well as elements on the second section of the retaining plate that are suitable to function together with mating elements on a chuck mounted on the work table for precise positioning of the first section within the work area.
