Embodiment Construction

[0012] With reference to the attached drawings, the supporting jig structure for making holes of the double ear piece part includes a jig body and an ear piece holder. The jig body has a horizontal base 1 and a vertical datum 2 on the horizontal base 1. The side of the reference block 2 is provided with a connecting piece for fixing the double ear piece parts 11, and the upper end of the reference block 2 is provided with a flat plate-shaped drilling template 3, which is provided with a drilling film hole 4 and a through hole 6 for connecting the ear pads , There is a compression hole 12 and a compression bolt 7 perpendicular to the through hole on the outer side of the drill template 3. The ear piece holder is a structure composed of a hook bolt 10 and a hook sleeve 8. The upper end of the hook bolt 10 has an external thread and is screwed with the knurled nut 5, and the lower end forms a hook holder. The outer diameter of the hook sleeve 8 matches the through hole on the drill...

Abstract

Disclosed is a support drill jig structure for drilling a double lug piece part. The support drill jig structure for drilling the double lug piece part comprises a drill jig body and a lug piece support, wherein a drill jig hole and a through hole connected with the lug piece support are formed in a drill jig plate of the drill jig body, a compression hole vertical to the through hole and a compression bolt are further located on the outer side of the drill jig plate, the lug piece support is of a structure composed of a hooked bolt and a hooked sleeve, two bending hook supports are respectively corresponding to two lug pieces of a part, a wedge groove is formed in the upper end of the hooked sleeve, and the compression bolt is pressed in the wedge groove through the compression hole.

Description

Technical field [0001] The present application relates to the manufacture of aircraft parts, in particular to a supporting drilling jig structure for making holes of double-ear piece parts. Background technique [0002] Aircraft parts are complex and have different shapes. The double-ear parts are one of them, which are characterized by thin ears and long cantilevers. The auxiliary support of the traditional drilling template in the process of making the hole of the double-ear piece part is generally composed of a double-headed screw, a hexagonal nut, and an adjusting nut. During mechanical processing, the auxiliary support is easy to loosen and cannot be self-locked. The product is easy to vibrate and lead to over-tolerance or even scrap. Workers need to repeatedly adjust during the operation, and the operability is poor. In order to eliminate the vibration of the ear flaps and ensure the processing accuracy in a limited space, a suitable support method must be adopted. Summar...
