Embodiment Construction
[0010] The present invention will be described in further detail below with reference to the accompanying drawings.
[0011] The invention provides an aircraft circular-arc windshield glass drilling tool, which is composed of a male mold (3), a female mold (4) and related parts thereon. The outer surface and contour of the male mold (3) are consistent with the inner surface and contour of the aircraft arc windshield glass (1), and the two ends of the outer surface are respectively engraved with marking lines CC' and DD' of the symmetrical generatrix; the male mold (3) ) has four supporting feet (7) at the large and small ends, each supporting foot has a through hole (12), and its upper plane and the female mold (4) correspond to the lower planes of the four supporting feet (9) to fit; There is a diamond-shaped pin (8) on the supporting foot of the small end of the mold (3), and a cylindrical pin (14) is arranged on the supporting foot of the large end opposite to it; The posi...

The invention discloses an arc-shaped windshield glass drilling tool; when a bolt is used for connection in the installation of the arc-shaped windshield glass of a plane, a mounting hole is drilled on the surface of the glass. The invention aims at providing a positioning and clamping process and device for drilling the mounting holes for the arc-shaped windshield glass of the plane, in order to ensure the drilling quality of the mounting holes of the arc-shaped windshield glass of the plane, and increase the work efficiency. The tool comprises a male mould (3) and a female mould (4) and parts thereon, and is characterized in that the outer surface and the outline of the male mould (3) are identical to the inner surface and the outline of the plane arc-shaped windshield glass; the inner surface of a glass blank part (18) clings to the outer surface of the mal mould (3), in order to realize axial and circumferential positioning of the glass blank part; the mal mould (3) and the female mould (4) are fixedly connected through positioning pins (8) and (10) and a bolt (10); a screw (5) is screwed up on the female mould (4) to clamp a glass blank (18) effectively; the processing position of the mounting hole is ensured accurate through a guide drill sleeve (6) on the female mould (4).
Description
technical field [0001] The invention belongs to the field of aviation manufacturing, and relates to a drilling tool for arc windshield glass of an aircraft. Background technique [0002] The arc windshield glass of the aircraft is made of transparent flat plexiglass, which is a kind of conical glass with high surface quality requirements. When the arc windshield of the aircraft is installed with bolts, the installation holes must be drilled on the surface of the windshield. The mounting holes are evenly distributed on the edge of the arc windshield glass, the number may be dozens, and the position accuracy of the mounting holes is required to be high. The axis direction of the hole is consistent with the normal direction of the surface position of the arc windshield glass. It is difficult to position and clamp the windshield when processing the arc windshield of an aircraft. The positioning must ensure the position accuracy of the mounting holes on the glass surface and at ...
