Abstract: In a clamping table (1) for workpieces (8) in a machine tool, which includes a plurality of mutually juxtaposed clamping elements (3) which each have a respective telescopic tube unit (10) with a top-end suction plate (11), wherein the concentric tubes (13, 14) of the telescopic tube unit (10) are displaceable relative to each other by a positioning drive (12), the positioning drive (12) is arranged coaxially with respect to the telescopic tube unit (10) and either is releasably coupled to the displaceable telescopic tube (13) by means of a positively locking plug coupling (21, 25) or is permanently coupled to the displaceable telescopic tube (13) and is connected electrically to a power supply (53) by means of a releasable plug connection (50, 52).

Abstract: In a device for the translatory positioning of a platform (1), in particular a tool mount, with articulated rods (2a, 2?a9 of invariable length, whose first ends are hinged to he platform (1), and whose second ends are coupled with respectively independent rail-mounted slide blocks (3), wherein the coupling points (9) on the platform (1) and coupling points (11) on the sliding blocks (3) respectively do not lie on a straight line, and the articulated rods (2a, 2?a) do not run parallel to either each other or a shared plane, only three independent sliding blocks (3) and accompanying initial articulated rods (2a, 2?a) are present. In a first variant, at least one of the coupling points (11) on the sliding blocks (3) is offset relative to the rail axis (4a), and all sliding blocks (3) are arranged on the same rail (4). In a second variant, all sliding block (3) are arranged on the same side horizontally next to the space provided for postioning the platform (1), and essentially run parallel to each other.
