A self-centering vise having reduced vertical size capable of exerting on workpieces a force exceeding 2000 kg. The vise comprises a body, two or more jaws constrained to the body and actuators of the jaws. The jaws can be moved close to and away from a workpiece gripping axis. Each actuator comprises a thrust element susceptible to displacements by a pressurized fluid. Each jaw comprises two guides inclined and symmetrical with respect to the displacement direction of the same jaw, and the thrust element of each actuator comprises two walls inclined and symmetrical with respect to the displacement direction of the same thrust element. Each actuator exerts its thrust simultaneously on two jaws, by slidingly engaging the guides of two jaws with its own inclined walls, according to a configuration that can be defined double inverted wedge configuration.

A strut channel clamp includes a block that can be positioned anywhere along the length of the strut channel. In embodiments, the stop can be repositioned to any of a plurality of locations along the channel. In certain embodiments, the stop and block can be placed on different surfaces of the strut channel. In some embodiments, a threaded shaft engaged with the block imparts force against the stop, and in some of these embodiments the shaft can be disengaged quickly from the block and repositioned longitudinally without rotation thereof. In various embodiments, the stop and/or block are constructed partly or entirely from common, off-the-shelf strut channel accessories. In embodiments, the block is rotatable.

A fixture block composite structure for workpiece positioning comprises a fixture block group composed of at least a stop fixture block and at least a one-sided movable fixture block. The stop fixture block is fixed to a base by a plurality of mountings, and two opposite lateral sides of the stop fixture block in the extending direction of base are provided with a fixed upright positioning plane respectively. The one-sided movable fixture block has a fixed holder, the holder is fixed to the base by a plurality of mountings. The holder is provided with a movable piece which can be driven to reciprocate towards the positioning plane on the stop fixture block. The movable piece is provided with a clamping surface on one side facing the positioning plane.

The clamping device according to the invention for clamping at least two processing devices for a sample preparation is made up essentially of at least three clamping blocks arranged in the axial direction, at least two of which are designed as movable clamping blocks, and a displacement mechanism for displacing the movable clamping blocks between an open position for inserting the processing devices, and a clamping position in which the at least two processing devices are clamped one on top of the other in the axial direction between two clamping blocks in each case. The displacement mechanism is designed for displacing the at least two movable clamping blocks in opposite directions.
