[0002] In the modern aviation manufacturing industry, products are increasingly connected and fixed using bolts in conjunction with support nuts. Some support nuts require support nut washers, which only have bolt holes but no rivet holes. Rivet holes must be manually made before using the support nut washers. The current method for making rivet holes for support nut washers involves drawing the locations of the rivet holes on the support nut washers and then making the rivet holes on the support nut washers according to the drawn lines. This not only increases labor intensity and reduces hole-making efficiency, but the rivet holes made by manual marking are not aligned with the rivet holes on the support nut and cannot be used.

[0005] Preferably, the positioning structure includes a sleeve and a positioning rod, the sleeve is arranged on the base, the positioning rod is arranged in the sleeve and extends axially along the sleeve, and its end extends out of the top of the sleeve; the positioning rod is adapted to the positioning hole of the support plate nut gasket to be made, and the support plate nut gasket is confined in the sleeve by a fastener.

[0006] Preferably, the positioning structure further includes rivet holes, which are arranged on both sides of the positioning rod and pass through the base.

[0007] Preferably, the hole-making drill sleeve includes a base plate, a positioning hole, and a vertical drill sleeve. The base plate has the same shape as the support plate nut gasket to be drilled; the positioning hole is opened on the base plate; the vertical drill sleeves are arranged on both sides of the positioning hole; a drill sleeve hole is opened along the axis of the vertical drill sleeve, the inner diameter of the drill sleeve hole is consistent with the inner diameter of the rivet hole to be drilled, and the drill sleeve hole passes through the base plate.

[0008] Preferably, the axial height of the vertical drill sleeve is greater than the axial height of the positioning hole.

[0009] Preferably, a plurality of positioning structures are provided on the base.

[0010] Compared with the prior art, the utility model has the following advantages: it can improve the hole-making efficiency and hole-making accuracy of the rivet holes of the support plate nuts and washers, and reduce labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS
