Abstract
A riveting apparatus which includes an elongated mandrel, a mandrel gripping mechanism, a mechanism for feeding rivets forwardly along the mandrel, and an abutment provided by a plurality of members, and a control system including an actuation device such that, upon actuation by an operator of the actuation device, the control system controls the riveting apparatus so that the rivet feeding mechanism is activated and deactivated, the abutment members are closed or opened, and the mandrel gripping mechanism is activated or deactivated, with a time delay between each step, to enable rapid removal and replacement of the mandrel.
Claims17
A riveting apparatus, which comprises:
- an abutment;
- an elongated mandrel, having a head at one end and loaded with a plurality of tubular rivets forming a column of rivets on the mandrel;
- a gripping mechanism gripping said mandrel, said gripping mechanism being located in proximity with an end of said mandrel remote from the head;
- a mechanism reciprocating said mandrel relative to said abutment by relative reciprocation between the gripping mechanism and the abutment such that the rivets in the column are fed forwardly along the mandrel so that a leading rivet nearest the mandrel head is positionable between the mandrel head and the abutment and is settable by moving the mandrel rearwardly relative to the abutment so as to draw the head of the mandrel through the bore of the rivet while the rivet is supported by the abutment;
- a mechanism feeding the rivets forwardly along the mandrel, said abutment comprising a plurality of members movable between a closed position to form said abutment and to support a rivet and an open position to allow free passage of rivets therebetween;
- and
- a control system including an actuation device, such that, upon actuation by an operator of the actuation device when the riveting apparatus has said mandrel located therein, the control system controls the riveting apparatus, wherein said control system comprises:
- a mechanism deactivating the rivet-feeding means
- a mechanism opening the abutment member and
- a mechanism deactivating the gripping mechanism
- so that the mandrel and any rivets remaining thereon are readily removable from the apparatus.
A riveting apparatus, which comprises:
- an abutment;
- an elongated mandrel, having an head at one end and loaded with a plurality of tubular rivets forming a column of rivets on the mandrel;
- a gripping mechanism gripping said mandrel, said gripping mechanism being located in proximity with an end of said mandrel remote from the head;
- a mechanism reciprocating said mandrel relative to said abutment by relative reciprocation between the gripping mechanism and the abutment such that the rivets in the column are fed forwardly along the mandrel so that a leading rivet nearest the mandrel head is positionable between the mandrel head and the abutment and is settable by moving the mandrel rearwardly relative to the abutment so as to draw the head of the mandrel through the bore of the rivet while the rivet is supported by the abutment;
- a mechanism feeding the rivets forwardly along the mandrel, said abutment comprising a plurality of members movable between a closed position to form said abutment and to support a rivet and an open position to allow free passage of rivets therebetween;
- and
- a control system including an actuation device, such that, upon actuation by an operator of the actuation device when the riveting apparatus has said mandrel located therein, the control system controls the riveting apparatus, wherein said control system comprises:
- a mechanism activating the mandrel-gripping mechanism;
- a mechanism activating the rivet-feeding mechanism;
- and a mechanism closing the abutment members
- so as to prepare the apparatus for further setting of rivets.
