Patent number: 5661892Abstract: The present invention provides a method and apparatus for positioning tooling with respect to a curvilinear workpiece which is curved in a first direction extending along a plane substantially perpendicular to the longitudinal axis of the workpiece and which is curved in a second direction extending along a plane to the workpiece longitudinal axis, the degree of curvature in the first direction being greater than the degree of curvature in the second direction. An illustrative example is automatic drilling, inserting and upsetting one or two piece fasteners such as exterior skin rivets on an airplane fuselage. Inner and outer positioning systems carry or support inner and outer tooling, respectively, which engage the workpiece from opposite sides thereof during tooling operations thereon.Type: GrantFiled: June 7, 1995Date of Patent: September 2, 1997Assignee: Gemcor Engineering Corp.Inventors: Mark J. Catania, Jeffrey P. Weaver, Thomas H. Rummell, Robert J. Kellner

Patent number: 5653005Abstract: A programmable or flexible fixture for holding a plurality of details comprising an assembly during assembly processes thereon comprising an elongated base supported in a predetermined position, a plurality of positioning units located at spaced locations along the base, each of the positioning units having a clamp adapted to engage the details, the positioning units being located to allow access to the details from two directions of movement of tools of assembly apparatus moving with respect to the workpiece during assembly processes thereon, a robot operatively associated with the positioning units for moving the positioning units relative to the base for accepting the various members of a family of details which all have the same configuration and differ by increments in size and for holding the details together as an assembly and holding the assembly in the proper detail location and assembly position for assembling, and an actuator for moving the clamp into and out of engagement with the details.Type: GrantFiled: June 21, 1993Date of Patent: August 5, 1997Assignee: Gemcor Engineering Corp.Inventors: Thomas H. Speller, Sr., Jeffrey P. Weaver

Patent number: 5611130Abstract: A method and apparatus for positioning tooling with respect to a curvilinear workpiece which is curved in a first direction extending along a plane substantially perpendicular to the longitudinal axis of the workpiece and which is curved in a second direction extending along a plane substantially parallel to the workpiece longitudinal axis, the degree of curvature in the first direction being greater than the degree of curvature in the second direction. An illustrative example is automatic drilling, inserting and upsetting one or two piece fasteners such as exterior skin rivets on an airplane fuselage. There is provided a head for supporting a plurality of tools at spaced locations around a central axis wherein each of the tools has an operational axis disposed substantially parallel to the central axis and an arrangement for moving the head along paths of travel relative to the workpiece to reach various locations on the workpiece where the tools are to perform operations on the workpiece.Type: GrantFiled: June 28, 1993Date of Patent: March 18, 1997Assignee: Gemcor Engineering Corp.Inventors: Thomas H. Rummell, Jeffrey P. Weaver, Robert T. Flaig, Thomas E. Burns

Patent number: 5248074Abstract: Riveting apparatus for operation on a workpiece having opposite sides and supported vertically on a horizontal surface comprising a frame having a pair of spaced apart sides movable along the supporting surface and straddling the workpiece, first and second carriages movably mounted on respective sides of the frame and riveting tools on first and second heads on the first and second carriages, respectively, the tools being movable toward and away from the workpiece. The frame travels in a first direction along the supporting surface and along the workpiece, the first and second carriages are movable in a direction substantially perpendicular to the first direction and toward and away from the supporting surface, and the frame is movable in a third direction transverse to the first direction and toward and away from the workpiece.Type: GrantFiled: September 12, 1990Date of Patent: September 28, 1993Assignee: Gemcor Engineering Corp.Inventors: Thomas H. Speller, Sr., John W. Davern, Jeffrey P. Weaver, Mark J. Andrews
