Abstract: Tool assembly for riveting parts, comprising: a first and a second frame (2, 5) capable of being mounted on a shaped structure "C" or on separate robot arms (60, 61); a pair of sheet-holding devices (3, 6) each mounted on one of the frames and at least one of each is provided with a device (11) for displacing it relative to the corresponding chassis with a force corresponding to the clamping provided for holding the parts to be riveted during drilling; at least one drill (20, 21) mounted on a frame, a device (41) for placing a rivet (40) in a hole drilled by the drill, this device being carried by a frame; a percussion riveting hammer (51) carried by a frame and an associated counter-piece (54) carried by the other frame, integral with a reaction dolly (52). The elements carried by each frame are all capable of being displaced between an active position and a rest position.

Abstract: Detachable device for joining together objects having holes intended to come into alignment, comprising:a tubular member made of an elastically deformable material and capable of passing through the holes when it is in the expanded state and of widening in order to be locked in the holes,an expansion rod sliding inside the tubular member and having a widened head,a body fastened to the tubular member and having a bore which extends the bore of the tubular member, and a support surface substantially at right angles to said bore,a locking member which can be immobilized at any point on the rod,an elastic member capable of exerting a determined force tending to move the body away from the locking member.The tubular member, the body and the elastic member preferably form a single piece.
