Supporting plate nut drill jig structure

The utility model relates to the field of aircraft assembly auxiliary devices, in particular to a supporting plate nut drill jig structure which can drill rivet holes corresponding to supporting plate nuts of multiple marks through one supporting plate nut drill jig, and therefore the drilling efficiency of the rivet holes corresponding to the supporting plate nuts is greatly improved. Comprising a drill jig body composed of a handle part and a positioning part fixedly connected with the handle part, the positioning part is provided with a center hole positioning pin, at least one rivet positioning hole and at least two pairs of supporting plate nut positioning drill holes arranged in pairs, and the center hole positioning pin extends outwards in the direction perpendicular to the surface of the positioning part. And rivet positioning pins are detachably arranged in the rivet positioning holes. The supporting plate nut drilling device is particularly suitable for the supporting plate nut drilling technology.
