Drilling tool for airplane sliding rail

Abstract

The invention relates to a drilling tool for an airplane sliding rail. The drilling tool comprises an L-shaped drill template (1), wherein a bending part of the L-shaped drill template (1) is fixed and reinforced by using a reinforcing angle plate (2), the inner surface of the drill template (1) is clung to the exterior of the side surfaces of a sliding rail front bracket (7) and a sliding rail rear bracket (8), a bent handle pin (5) is installed at the front end of the drill template (1) and connected with a precast positioning hole in the sliding rail front bracket (7) for positioning, two positioning bolts (3) and knurled nuts (4) are installed at the rear end of the drill template (1) and connected with two precast positioning holes in the sliding rail rear bracket (8) for positioning, two drill bushing holes (6) are formed in the middle of the drill template (1), the positions of the two drill bushing holes (6) correspond to those of two holes to be machined in a sliding rail middle bracket (9), and the diameter of the two drill bushing holes (6) is 5 plus or minus 0.2mm. The drilling tool facilitates drilling in the installation of the airplane sliding rail, avoids deviation occurring in pre-installation of a finished product of the sliding rail, ensures the drilling quality, satisfies the requirement on the interchangeability of the sliding rail, and improves the percent of pass of the product.

Description

technical field [0001] The invention is an aircraft slide rail hole-making tool, which belongs to the technical field of product structure and is used for riveting assembly of aircraft. Background technique [0002] For EC120 aircraft, the installation between the slide rail on the cabin sliding door and the aircraft structure is generally to pre-install the finished slide rail on the aircraft structure through the connecting bolt holes, adjust the gap between the periphery of the slide rail and the bracket frame beam, and then Drilling to the aircraft structure according to the holes on the finished product, this method is called the matching method. The slide rails after riveting assembly using the traditional photo-matching method can only be installed with corresponding matched finished products, which cannot meet the interchangeability requirements of the products and reduce the qualified rate of the products. Due to the limitation of the procurement cycle of finished ...

AI Technical Summary

Problems solved by technology

The slide rails after riveting assembly using the traditional matching method can only be installed corresponding to the finished products after matching, which cannot meet the interchangeability requirements of the products and reduce the qualified rate of the products

Due to the limitation of the procurement cycle of finished slide rails, structural drilling cannot be carried out without finished slide rails, so the riveting assembly task cannot be completed according to the production plan, which affects the scheduled delivery of the aircraft
