Filed:

Jun 4, 2001

Appl. No.:

09/874542

Inventors:

Peter B. Zieve - Seattle WA
Carter L. Boad - Lynnwood WA
Sam O. Smith - Woodinville WA
Scott E. Neel - Everett WA
Brent W. Huffer - Everett WA

Assignee:

Electroimpact, Inc. - Mukilteo WA

International Classification:

B23P 2100

US Classification:

29788, 29818, 294104

Abstract:

The system includes means for moving a rivet or a collar from a storage bin to an initial position for the respective gripping assemblies. The presence of the rivet and/or collar is recognized as it moves through a feeding mechanism. After the rivet or collar is gripped, they are moved either into an opening in the workpiece, in the case of a rivet, or onto the tail of a lockbolt, in the case of a collar. The gripping assembly is then released from the rivet or the collar, with the gripping means moving back to an initial position. Further operations can then be carried out on the rivet or collar.

US Classification:

292435, 29505, 29715, 29718, 227112, 227119

Abstract:

A system and method for feeding collar members to an attachment system for assembly of aircraft and similar large scale mechanical assemblies. Collars are fed sideways along a tube having a rectangular internal cross-section to a collar pathway defined by an clamp fork and swaging ram combination. The collar pathway is curved to present the collar to a receiving element mounted on a swaging die in a proper orientation relative to an attachment bolt which is moved through an opening in the workpiece and then through the collar. As the bolt is moved into the collar, the collar, receiving element and swaging die move together laterally to come into alignment with the bolt.
