METHOD FOR ATTACHING A HEADLESS CRIMP NUT TO A SANDWICH PANEL

摘要

The invention lies in the field of bolted connections for panels and, in particular, for sandwich panels used in aeronautics and space. It relates to a method of fixing a crimping nut headless on a wall of such a panel. According to the invention, the method comprises the following steps: * injecting a predetermined quantity of glue (35) into a blind hole (34) formed on the wall (31) of the panel (30); * Assemble the crimping nut without head (10) on a crimping tool (40), the crimping tool (40) having a piercing plate (42) and a screw (41) passing through the plate support (42), the screw (41) being screwed into the crimping nut (10) so as to press the crimping nut (10) onto the support plate (42); * position the crimping nut without head (10) in the blind hole (34), the support plate (42) bearing against the wall (31) of the panel (30); crimping the crimp nut (10) so as to clamp the wall (31) of the panel (30) between the bearing plate (42) and a bead (18) formed by deformation of the crimp nut (10). ).
