Abstract: In the case of a clamping device (1) for holding a workpiece (3) to be machined by a machine tool (2), consisting of a housing (4), at least one clamping jaw (7) mounted in the housing (4) so that it is axially movable and a counter-stop (10) formed by the housing (4), between which the workpiece (3) is clamped or at least two clamping jaws (7, 8, 9) mounted in the housing (4) so they are axially movable, between which the workpiece (3) is clamped, and an electrically operated drive device (11), by means of which the movable clamping jaws (7, 8, 9) are movably controlled, and by means of which a holding force, transmitted by the clamping jaws (7, 8, 9) to the workpiece (3) or by a clamping bolt (3?) coupled with the workpiece (3), is generated during the clamping process, both an automated insertion as well as a clamping device (1) are supposed to be further developed, by means of which an automated position check of the inserted workpiece (3) can be carried out, and by means of which, when the test result is

Abstract: A zero-point clamping device for centering an object (2), the device comprising: a housing (4), a receiving opening (5), and two opposite clamping slides (7, 8) mounted axially displaceably in a bore (9) in the housing (4), which open into the receiving opening (5) during clamping and act on the object (2) to center it, wherein clamping is achieved by an actuating element (11) rotatably mounted in the housing (4), the axis of rotation (12) of which runs parallel to the clamping slides (7, 8), a through-opening (13) aligned perpendicularly to the clamping slides (7, 8), and a pivot pin (14, 15) inserted into the through-opening (13), one free end (16) of which engages in a guide groove (18) in a driving arrangement, and the opposite free end (17) of which is inserted into an abutment (21) associated with the housing (4) and is held in a tilting arrangement.

Abstract: In a zero-point clamping device (1) for centered locking of an object (2) with repeat accuracy, in particular a workpiece, a tool or a pallet, the zero-point clamping device comprising: a housing (4), a receiving opening (5) worked into the housing (4), which has a centering axis (6) with which the object (2) is aligned during the clamping process, and two opposite clamping slides (7, 8), each of which is mounted axially displaceably in a bore (9) provided in the housing (4) and which open into the receiving opening (5) during the clamped condition and thereby act on the object (2) or a carrier part (32) and center it, on the one hand, this should enable a reliable, permanent and repeatable fixing of a large number of workpieces, tools, pallets or other objects (2) and, on the other hand, the housing (4) of the clamping device (1) should be extremely compact, i.e. its external dimensions can be kept extremely small in height and diameter.
