Floating barrel nut assembly device

The invention relates tobarrel nuts and screw assembly devices, more particularly to floating barrel nut devices. Barrel nuts are in common use, particularly in aeronautics. The barrel nut having the simplest form is a cylindrical part equipped with a radial tapped hole. It is placed in a bore made in a first of two parts which it is desired to assemble. This first part is also provided with a screw hole extending perpendicularly to the bore and emerging in the latter.
Such as assembly device offers, in particular, the advantage that the screw can be screwed into the barrel nut without it being necessary to hold the nut, even when the latter is provided with a thread stop, since the barrel is immobilized in the plane perpendicular to the axis of the screw. The play between the screw and the screw holes made in the two parts to be assembled may be large or small. The lack of centring between the screw holes and the tapped hole of the barrel nut when the latter is in place in the first part must be less than this play.
