Abstract: The invention concerns a process and the associated universal device for supporting a part (1) of random and/or possibly complex shape in relation to a rigid base (11) while establishing a work reference. It consists of inserting between the part to be held and the rigid base (11), at least one deformable airtight enclosure (3) of constant volume full of incompressible particles (4). Then vacuum is applied inside the deformable enclosure (3) of constant volume using a vacuum source (5) which can be connected to the deformable enclosure (3). Thus the particles (4) amalgamate to constitute a solid block which at least partially rests on the rigid base (11) and holds the part (1) matching its shapes.

Abstract: An automatically adjustable locking pliers or tool includes a jaw fixed to a first handle and a jaw that pivots about the first handle. The pivoting jaw is connected to a lower tightening handle. A lever connects the tightening handle and first handle. A self-adjusting sizing and locking mechanism includes a thumb jaw sizing piece located near the jaws and movable to open the jaws so that they can be sized around a workpiece. When the thumb jaw sizing piece is released, the jaws automatically size and clamp lightly around the workpiece. The locking mechanism uses balls between a locking rod and a tapered surface. Locking occurs when the balls wedge between the rod and the tapered surface. A release cylinder is connected to a release paddle movable to unlock the mechanism. The sizing piece and locking mechanism are operable to automatically size and lock the pliers or tool.
