An automatic riveting gun and a method of operating same are disclosed, the automatic riveting gun includes a gun body including a rivet cavity, a front cavity, and a main cavity; a rivet clamping assembly is disposed on the gun body adjacent to the rivet cavity; a front-dynamic structure is movably disposed in the rivet cavity and the front cavity and a main-dynamic structure is movably disposed in the front cavity and the main cavity. The front-dynamic structure includes a claw sleeve. A claw mechanism is movably disposed in the main-dynamic structure. A front elastic element provides an elastic force to the claw mechanism and a main elastic element provides an elastic force to the main-dynamic structure.

Apparatus is disclosed for attaching to a lockbolt via a swaged-mounted collar. The apparatus includes an element which permits relative movement between a cutting blade and an opposing surface so that the collar is held centrally within the apparatus during cutting.

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.
