Abstract: A locking device for mechanical pieces, particularly for pieces subjected to mechanical processing or similar, comprising at least one hollow body that forms a sliding seat, a movable stem that is accommodated slidingly partially within the sliding seat of the hollow body and radial expansion elements which are interposed between the hollow body and the movable stem, the radial expansion elements being adapted to mutually lock the hollow body and the movable stem, the movable stem protruding partially from the hollow body with the hollow body and the movable stem jointly associable, at their free ends, by way of elements for connection, respectively, to a mechanical piece to be processed or a fixed part of a machine with which the mechanical piece is to be processed.

Abstract: A modular structure, particularly for supporting blanks, which comprises at least one flat plate which has a plurality of seats which can be integrally and removably associated with at least one portion of a blank to be worked on by way of fixing elements, which comprise a fixing element that has at least one lower portion which can be faced towards the plate and which is provided with at least one pin which can be engaged, respectively, with a seat of the plate, and can be inserted along its axis in a cavity defined by a lower portion through a hole with a substantially elongated shape along a predefined direction and is substantially perpendicular with respect to the axis of the pin.

Abstract: A modular structure, particularly for supporting blanks, which includes at least one flat plate provided with a plurality of seats for interconnection between the plate and a blank or the like by at least one anchoring element, which includes a first part, which can be associated detachably with the plate, and a second part, which is provided with first fixing elements for the detachable connection of the anchoring element to a recess of the blank, where the first fixing elements include, in particular, fingers which can be inserted in the recess and protrude from the anchoring element along substantially one direction and can move transversely with respect to the direction for their engagement with the lateral surfaces of the recess.
