The present disclosure relates to a centering device for a nacelle of a turbojet engine providing the flush centering of an outer downstream panel of a thrust reverser with respect to a cowl of a fan casing. The centering device includes, in one single piece: a sub plate allowing the fixing of the centering device to the fan casing; a first positioning arm integrally formed with the sub plate, protruding upstream, in such a manner as to form, with respect to a directing axis (A) of the nacelle; a first radial abutment designed for guiding the cowl of the fan casing; and a second positioning arm, integrally formed with the sub plate, protruding downstream, in such a manner as to form, with respect to the directing axis (A) of the nacelle, a second radial abutment designed for guiding the outer downstream panel.

Assembly centering device for turbojet engine nacelle

An assembly device includes a framework resting on a planar support, a support element mounted movably in rotation relative to the framework, an immobilizing device, and a positioning assembly mounted in rotation on the support element. A front frame of the fixed structure is positioned on the positioning assembly, and the immobilizing device is arranged to immobilize the front frame on the positioning assembly. In particular, the assembly device allows, in the immobilizing position on the positioning assembly, for the front frame to extend transversely to the planar support.

This gauge for mounting a screw in a cage nut or in a nut (), with the aim of assembling at least two parts (), comprises a shank () with a smooth section () having graduations () and with a threaded end (), which are similar to those of said screw. A sleeve () is slidably mounted on said smooth section (). The axial length of said sleeve () and the distribution of said graduations () are such that, when the shank () of said gauge is screwed as far as it will go into said cage nut or into said nut () and when said sleeve () is pressed against one () of said two parts (), the graduation indicated by said sleeve () on said smooth section () is representative of the distance separating the thread () of said cage nut or said nut () from the outer surface of the part () situated facing away from this cage nut or said nut ().
