US Patent:

56154747, Apr 1, 1997

Filed:

Sep 9, 1994

Appl. No.:

8/303535

Inventors:

Robert J. Kellner - Orchard Park NY
Mark F. Cassidy - Orchard Park NY

Assignee:

Gemcor Engineering Corp. - Buffalo NY

International Classification:

B23Q 15007
B23Q 1522
B23P 2100

US Classification:

29703

Abstract:

The present invention relates to a system control for directing and monitoring the operation of an automatic fastening machine, such as automatic drilling and riveting machine, by gathering, recording, and processing relevant data from each drilling and riveting cycle. The cycle data then becomes part of a master record that is useful for logging maintenance schedules, for establishing real-time cycle trends and for historical purposes. Real-time cycle trends are particularly beneficial to effect corrections in subsequent cycles.

Appl. No.:

7/971890

Inventors:

Bradley M. Roberts - Williamsville NY
Mark F. Cassidy - Orchard Park NY
John W. Zienkiewicz - North Tonawanda NY

Assignee:

Gemcor Engineering Corporation - Buffalo NY

International Classification:

B21J 1512

US Classification:

29705

Abstract:

In an automatic fastening machine 10 comprising a frame 12 for operating a workpiece 16 along a work centerline and having a drilling tool for drilling a hole in the workpiece, a bucking ram 26, and a milling tool 30 having a hole inspection assembly 22 mounted on the upper ram 88 thereof. The hole inspection assembly includes a hole probe assembly 24 that is movable axially along the work centerline to insert a probe member 25 into a position inside the hole in the workpiece. The probe is provided with a plurality of capacitor plates 25B that measure the peripheral extent of the hole to insure that the hole is drilled within a tolerance range and is also properly positioned on the workpiece before a fastener is inserted. The probe assembly has several proximity limit switches 138 and 152 that detect movement between a cylinder bracket 72 biased to a probe connector 74 to signal a central processor 300 to discontinue axial movement of the probe along the work centerline should the probe contact the workpiece or a foreign object before it locates properly inside the hole.
