An example system includes: an apparatus comprising: a temporary fastener having a stem configured to be inserted through as assembly and be retained to the assembly, and a spring mounted about the stem. The system also includes a linear actuator configured to apply a force on the spring, thereby causing the spring to be compressed against the assembly and apply a predetermined clamping force to the assembly.

Quick-clamping spindle contains two pieces, firstly a spindle body supplied with a clamping member at one of the ends thereof and secondly a control rod for controlling the use/withdrawal of said clamping member, which rod is contained in said spindle body as well as a member for maneuvering and controlling the clamping member placed at the other of the ends of said spindle body, which simultaneous control member has a helical ramp provided in the wall of said spindle body engaging a transverse shaft borne by said control rod. The spindle further has a device for rotationally blocking the control rod in the spindle body. It is intended for use in the machining field.

A removable blind fastener includes an anti-rotation body having an external face with an aperture, the external face being suitable for engaging with a surface of a work-piece to be clamped. The fastener further includes a hollow leg member with a plurality of slots defining outwardly biasable resilient legs at one end and an externally threaded portion at the other end, the leg member having a bore tapering towards the legs, the leg member being translatable through the aperture, the leg member and the aperture further having inter-engaging anti-rotation features to prevent the leg member from rotating about its central axis relative to the anti-rotation body. The fastener may further include a thread tube with an internal thread cooperable with the external thread of the leg member and located co-axially with the leg member and a rod member having a shaft with a head end and a free end.

Insertable clamp (100), for the temporary assembly of at least two drilled structural parts (200a, 200b), including a main tubular body (10) extending along a longitudinal axis X and having a bearing surface (111) intended to come into contact with a first face (201a) of the structural parts, an elastic clip (30) capable of passing through drilled aligned holes, produced in said parts, the clip being translationally moveable along the longitudinal axis, driven by the rotation about said axis of a driver nut (50) provided with a tapped bore (51) cooperating with a threaded end (31) of said clip, the clip (30) comprising two branches (32) each ending by a hooking spur (33) intended to come into contact with a last face (202b) of the structural parts, said branches transversally and progressively moving apart along a spreader (40), placed between said branches and fixed in relation to the main body (10), when exposed to the recoil of the clip, the clamp further includes a compression spring (60) placed inside the main body (10) and holding the threaded end (31) partially engaged in the tapped bore (51) so that the clip (30) remains constantly aligned with the longitudinal axis.

The present invention concerns a fastener (110) for the temporary assembly of at least two previously drilled structures (112) comprising: a hollow body (122) comprising a bearing surface (40); elastic clips (24) which are movable relative to the body and which form a projection relative to the bearing surface; a spacer (26) around which the elastic clips are positioned; a connecting element (130), extending within the body and secured to the elastic clips (24); and an actuating element (132) linked to connecting element by a thread/tapping (67, 84).

The connecting element is traversed by a lateral opening (70) axially extended between two closed ends (72, 74); and the fastener also comprises a transverse stop (28) secured to the spacer, the said stop being capable of sliding between the axial ends of the said lateral opening.

A method enabling two holes belonging to two parts to be aligned relies on use of a tool, comprising a body, having a first outer surface which gradually wanders from a longitudinal axis of the body as it extends from a first end of the body, and a hollow part having a second outer surface with a complementary section to the section of the holes. The hollow part comprises a hole through which it is removably mounted on the tool so that the second outer surface extends the first outer surface on an opposite side to the first end of the body. The method comprises inserting the first end of the body into the first hole, and then operating the tool to push the body and then the hollow part together into the holes. This method especially applies to the assembly of a floor module to an aircraft fuselage.

The present invention concerns a fastener (110) for the temporary assembly of at least two previously drilled structures (112) comprising: a hollow body (122) comprising a bearing surface (40); elastic clips (24) which are movable relative to the body and which form a projection relative to the bearing surface; a spacer (26) around which the elastic clips are positioned; a connecting element (130), extending within the body and secured to the elastic clips (24); and an actuating element (132) linked to connecting element by a thread/tapping (67, 84). The connecting element is traversed by a lateral opening (70) axially extended between two closed ends (72, 74); and the fastener also comprises a transverse stop (28) secured to the spacer, the said stop being capable of sliding between the axial ends of the said lateral opening.

The present invention concerns a fastening socket (112) for assembling at least two previously drilled structures, said socket comprising a substantially cylindrical body (34) and an enlarged head (35); said enlarged head comprising first mounting surfaces (42, 46) suitable for being assembled to a first installation component and for preventing said first installation component from rotating about the main axis. The socket comprises a first substantially cylindrical recess (40) extending along the main axis from the first end, said first recess ending at a planar shoulder (44) substantially perpendicular to said main axis, the first recess and the planar shoulder being received inside the enlarged head, the first mounting surfaces (42, 46) being formed by an inner surface of the first recess.

A grommet removal assembly includes a grommet and a grommet removal tool. The grommet includes a body defining a longitudinal axis, a plurality of arms extending from the body, the plurality of arms defining first engagement ramps, and a plurality of legs extending from the body. The grommet removal tool includes a shaft and a plurality of wings extending from the shaft and defining a plurality of second engagement ramps. The first engagement ramps of the wings are capable of engagement with the second engagement ramps along the plurality of arms to draw the arms inward, toward the longitudinal axis of the body.
