A tapered sleeve bolt removal tool for removing a tapered sleeve bolt includes a stop sleeve configured to be coupled to a threaded end of a bolt of the tapered sleeve bolt. The stop sleeve has a stop shoulder configured to abut against a bottom of a sleeve of the tapered sleeve bolt. The stop sleeve has a lateral dimension less than or equal to a lateral dimension of the sleeve to allow the stop sleeve to be removed through an opening with the bolt and the sleeve. A bolt extractor having a bolt engagement feature is configured to engage an extraction shoulder of the bolt. The bolt extractor is pulled in an extraction direction to pull the bolt, the stop sleeve and the sleeve to simultaneously remove the sleeve and the bolt from the opening in the component.

Method and tool for removing a tapered sleeve bolt from a component

A method of upsetting a headed rivet in a countersunk hole using an electromagnetic riveting machine having two opposed drivers which are impelled against each end of the rivet to upset the rivet with a single stroke of the machine. The movement of the driver at the headed end of the rivet in initiated slightly after movement of the driver at the shank end of the rivet to lift the headed end of the rivet slightly out of the countersink so, when the headed end driver operates, the rivet shank is deformed to fill the rivet hole as the head is driven back into the countersink for good shank interference in the hole adjacent the rivet head.

Method for upsetting a headed rivet by differential initiation of

A method of riveting includes drilling a hole in a workpiece with a drill bit held in a spindle mounted on an axial centerline of a drill/rivet machine. The drill descends through a drill/suction cavity of a movable shuttle and drill chips cut by the drill bit are suctioned away from the workpiece as they are made. The drill bit is withdrawn to a level just above the drill/suction cavity, which is then moved to position a rivet insert station over the newly drilled hole in the workpiece. A rivet is blown into the rivet insert station, is guided into alignment with the hole and injected directly into the hole by air pressure. The shuttle moves a rivet die over the newly installed rivet in the hole and a driver of an electromagnetic riveter is lowered into contact with the die, which in turn is pressed against the rivet head. Another rivet die is pressed against the rivet tail on the other side of the panel by a driver of another electromagnetic riveter. Both electromagnetic actuators are energized to propel the drivers toward each other and cause the dies to upset the rivet.

Method of riveting

This invention relates to a machine and its constituent components for drilling a hole in a workpiece, inserting a rivet in the hole, and upsetting the rivet, all without moving the lateral position of the machine or the workpiece, and to an assembly for supporting and positioning a plurality of said machines for working simultaneously on the workpiece.
