Abstract: The present invention relates to a clamping device having a mounting element with an axis of rotation X, an actuator, a support that has an opening of axis X in which opening the mounting element and the actuator are positioned. The mounting element includes a slide in which there are positioned a ring and a locking wedge which collaborate with at least one angle transmission. The support has an interior groove arranged in the opening and the ring and the locking wedge collaborate with the interior groove. The mounting element can thus easily be angularly positioned. There are preferably two angle transmissions positioned such that they are diametrically opposed.

Abstract: A device for clamping a workpiece on tool includes a ram and a clamp, the ram being selectively actuated by a pressurized fluid. The ram includes a body which, when in use, is secured to the tool and a slide mounted such that it can slide with respect to the body. The clamp is hinged with the slide about a pivot axis. The body includes a front face beyond which the clamp projects when it is in a clamping position in order to clamp the workpiece. In addition, the clamp has a release position which it reaches at least partially by pivoting about the pivot axis. The slide includes a piston and a rod that are assembled to one another. The pivot axis is offset by a predetermined distance with respect to the axis of the rod in the direction of the front face.

Abstract: A device for clamping a part to a tool includes an arm and a body that is fastened when in use to the tool, the arm being mounted in a movable manner on the body and being driven by actuating means between a clamping position and a releasing position, and undergoing a pure movement in translation along an arm axis at the end of its travel towards its clamping position and rotation about the same arm axis at the end of its travel towards its releasing position, the movement of the arm being determined by guide members.

Abstract: A rapid assembly system includes a mounting and a plate removably mounted onto the mounting. The system has connection devices between the plate and the mounting. Each device also includes a clamping means for holding the plate against the mounting; a tooth having a pair of tooth engagement surfaces arranged in a V-shape, the theoretical intersection of which extends in a tooth direction; and a groove with a pair of groove engagement surfaces for engaging the tooth engagement surfaces.

Abstract: An articulated fastening element (1) for use on a workbench, a machine bed, a vacuum table or the like, is composed of a flexible seal (2) which includes, in order to raise a workpiece to a predetermined height H, rigid raising elements (3) distributed over at least one of the side walls of the seal (2) and separated from each other by functional clearances enabling the fastening element (1) to be sharply bent.
