Abstract
There is provided an automated rivet apparatus for installing a semi-tubular fastener rivet. The apparatus includes a numerical control (NC) drilling and riveting machine and a controller. The NC drilling and riveting machine includes a lower head having a lower pressure bushing, a lower drill spindle, and a lower anvil to apply an upset force to a tail portion of the semi-tubular fastener rivet. The NC drilling and riveting machine further includes an upper head having an upper pressure bushing, an upper drill spindle, and an upper anvil that holds the semi-tubular fastener rivet to insert the semi-tubular fastener rivet in a rivet-receiving hole. The lower drill spindle countersinks the rivet-receiving hole from a lower side of a workpiece. The controller directs movement of a nose of the lower anvil to apply the upset force and form a predetermined flare contour in the tail portion within a lower countersink.
