摘要： The invention relates to a clamping arrangement with a clamping device (1) which is able to be fastened on a clamping base, and with a clamping element (26) able to be tightened thereon. The clamping device (1) has a clamping module (2), provided with clamping members (15), which is able to be fixed by means of a fixing element (3) on the clamping base, wherein the fixing element (3) is configured such that the clamping module (2) is thus fixed in the X-Y plane in a floating manner on the clamping base. The clamping module (2) is displaceable in the fixed state of the fixing element (3) with respect to the fixing element (3) in the X-Y plane, but is non-displaceable in Z-direction, wherein the fixing element (3) is provided with Z-support surfaces (24) for the clamping element (26). Such a clamping arrangement is suitable in a particularly advantageous manner as a module for constructing a large clamping system, with which thermally caused dimension changes of the workpiece carrier with respect to the clamping base can be equalized with high repeat accuracy, without the clamping system being overconstrained geometrically/mechanically in the X-Y plane.

摘要： A clamping device includes a clamping chuck and a clamping element, which can be clamped thereto. The clamping chuck has a receiving opening for the clamping element and clamping members for clamping the clamping element in the receiving opening. The clamping element is elongated, while the clamping chuck is provided with an elongated receiving opening for the clamping element. A resiliently flexible centering element, which aligns the clamping element in response to the insertion into the receiving opening at right angles to the longitudinal axis of the receiving opening, is arranged on the clamping chuck in the insertion area of the receiving opening. Such a clamping device is suitable in clamping systems by means of which large to very large workpiece carriers can be clamped in the work area of a machine tool in a repeatably accurate manner.

摘要： The measuring machine (1) for measuring workpieces (23, 23a) features a machine table (2) and a mechanical device comprising a measuring slide movable in a first linear axis and a cross slide movable in a second linear axis, and a quill shaft (7) arranged on the cross slide and movable in a third linear axis. Arranged on the quill shaft (7) is, in addition to a sensor (9) for measuring the workpiece, also a gripper (11) by means of which a workpiece (23a) can be retrieved from a magazine (22) and transferred to the clamping device (20), or retrieved from the clamping device (20) and transferred to the magazine (22). Due to this configuration the existing mechanical device of the measuring machine (1) can be made use of to mechanically transfer and also retrieve a workpiece (23, 23a) being measured.

摘要： The assembly comprises a coupling for direct or indirect coupling the core rod (15) to the lower punch (12) of a powder press. The coupling is configured as a magnetic coupling and comprising two coupling elements (20, 30), the first (20) of which is actively connected to the core rod (15) and the second (30) of which is actively connected to the lower punch (12). The magnetic coupling comprises several permanent magnets (24a, 24b, 33a, 33b) arranged at each coupling element. These permanent magnets (24a, 24b, 33a, 33b) are arranged and adapted to each other such that when coupling the two coupling elements (20, 30) the first coupling element (20) is automatically rotated by the effect of the field lines of the magnets (24a, 24b, 33a, 33b) into a predetermined angular position relative to the second coupling element (30).

摘要： A clamping chuck is provided for clamping palettes having a clamping spigot. The clamping chuck includes a receiving opening for the clamping spigot and a clamping device that includes an actuating piston displaceable between an initial position and a locking position for actuating clamping members for clamping the clamping spigot in the receiving opening. The clamping chuck includes a monitoring line that is acted upon pneumatically and leads from an inlet to an outlet. The receiving opening includes a conical insertion region, into which at least one control hole connected to the monitoring line emerges, the control hole being closed by the clamping spigot. A valve device is arranged between the inlet and the outlet of the monitoring line to vary the flow of a fluid through the monitoring line depending on the position of the actuating piston.
