An upper drill tool including a central chuck, an upper component, a lower component and a coupling assembly. The central chuck has a chuck base and a chuck structurally configured to retain a drill bit. The upper component is attached to the central chuck and has a lower stop surface. The lower component has a central body and an outer ring that threadedly engages the central body, with the outer ring having an upper stop. The coupling assembly is configured to facilitate the slidable movement of the lower component from a first orientation wherein the upper stop is spaced apart from the lower stop surface and a second orientation wherein the upper stop is in abutting engagement with the lower stop surface, with the first orientation and the second orientation defining a stroke.

A multiple anvil fixture possesses multiple anvils engaged to a base in a fixed relation to each other with the anvils are oriented in a common direction. Each of the anvils includes a first structure and a second structure. The first structure and the second structure are slidably engaged. Each of the anvils has an extended position and a recoiled position and a biasing-element to bias the first structure and the second structure in the extended position. The multiple anvil structure can be used to rivet brackets onto containers. The anvil protrudes through the container in the extended position to help align holes in the feet of the brackets with openings in the container. The anvil then recoils beneath the container to serve for the fixation of rivets.

An assembly includes an upper substrate, a lower substrate, and a self-piercing rivet. The lower substrate defines a preformed interior cavity and a preformed exterior profile adjacent the interior cavity to define a variable thickness wall. The self-piercing rivet extends through the upper substrate and into the preformed interior cavity of the lower substrate.

A system for attaching layers of material together comprised of a self-piercing rivet, a layer having a clearance hole through which the self-piercing rivet passes on assembly, and a layer free of a clearance hole and into which the self-piercing rivet is at least partially inserted. The system may include a third layer free of a clearance hole. The system may also include three layers wherein the clearance hole is formed in the middle layer. If the clearance hole is formed in the middle layer, the width of the hole may be greater than the diameter of the self-piercing rivet to avoid contact between the rivet and the middle layer. The layer having the clearance hole may be a hard material such as steel. One or more of the layers may be material that is difficult to pierce or can be damaged if pierced.

The disclosure relates to a method for screwing a locking ring onto a threaded bolt, wherein a coupling device for being threaded into the threaded bolt is driven in rotation by a rotary drive, and wherein the locking ring is then screwed onto the threaded bolt, which is fixed by the coupling device, by a locking ring holder which is driven in rotation by the rotary drive. The disclosure likewise relates to a method for screwing a locking ring comprising a fastening part and a tear-off part onto a threaded bolt, wherein a removal gripper grips the tear-off part and removes the tear-off part after the tear-off part has been torn off. The disclosure further relates to a screwing apparatus for executing a method according to the disclosure.

An aircraft panel production method has: a step in which a holding jig holds a body panel, which has a plurality of plate-like members having a curved cross-sectional shape, such that the cross section of the body panel has an upwardly bulging curved shape; a step in which the plate-like members of the body panel held by the holding jig are overlapped with each other and the overlapping portions are joined by a rivet; a step in which the holding jig, which is holding the body panel of which the plate-like members have been joined to each other, is moved; and a step in which a frame that follows the curved shape of the body panel is joined, by a rivet, to the plate-like members of the body panel which is held by the holding jig which has been moved.

Systems and methods are provided for fastening via a swage tool. One embodiment is a method for fastening via a swage tool, the method including selecting a hole located at a part; aligning an axis of a lockbolt collar with a center of the hole; placing the lockbolt collar flush against the part at a first end of the hole; and swaging the lockbolt collar onto a lockbolt that has been driven through the hole.

A method and rivet apparatus to rivet a workpiece comprises an upper riveting portion and a lower riveting portion. The lower riveting portion comprising a fixed base, support member, and a pin assembly. The pin assembly comprises a center pin, a forming pin, a first biasing member, an outer shroud, and a second biasing member. The center pin pushes against a tail of a rivet to deform the tail of the rivet. The forming pin, fixedly coupled to the support member, pushes against the tail of the rivet to deform the tail of the rivet. The first biasing member, disposed below the center pin, biases the center pin through the forming pin and away from the support member. The outer shroud encircles the forming pin and the center pin. The second biasing member, disposed below the outer shroud, biases the outer shroud away from the support member.
