Description

Technical Field

[0001] The invention belongs to the technical field of aircraft assembly connection, and relates to an aileron clutch hole making device and method. Background Art

[0002] The aircraft control system aileron clutch is composed of a left square bracket and a right herringbone bracket through a connecting rod. The left square bracket has 7 Φ6H8 connection holes with the wing rear beam column, and the right herringbone bracket has 4 Φ6H8 connection holes with the fuselage skin. At the same time, there is a certain angle between the brackets on both sides of the aileron clutch.

[0003] At present, in the production process of aileron clutch components, the left square bracket is drilled with 7 Φ4.5mm initial holes for connecting the bracket and the wing rear beam column according to the size required on the drawing when manufacturing the parts, and the right herringbone bracket is drilled with 4 Φ4.5mm initial holes for connecting the bracket and the fuselage skin according to the size required on the drawing when manufacturing the parts. After the square bracket and the herringbone bracket are manufactured, the brackets on both sides are connected through the middle connecting rod, and the angle between the square bracket and the herringbone bracket is guaranteed by the simple tooling. When the aileron clutch is installed on the aircraft, it is positioned through the initial holes drilled on the left square bracket and the positioning holes drilled on the wing rear beam column according to the assembly jig, and the gap between the bottom surface of the right herringbone bracket of the aileron clutch and the fuselage skin is checked. After the gap meets the requirement of ≤0.2mm, the bolt holes for connecting the herringbone bracket and the fuselage skin are drilled according to the 4 Φ4.5mm initial holes on the herringbone bracket. Since the connection holes on the aileron clutch assembly are drilled in the state of parts, there are errors in the assembly process of the assembly, and the relative position of the connection holes on the left square bracket and the right herringbone bracket cannot be accurately guaranteed. Therefore, when the aileron clutch assembly fails and needs to be replaced, there is a hole position misalignment phenomenon, and the hole connection has a problem of hole diameter deviation, and the aileron clutch assembly is not interchangeable when installed on the aircraft. At the same time, there is an angle between the left square bracket and the right herringbone bracket, which cannot be effectively controlled during assembly of the assembly, resulting in uneven gaps when the aileron clutch assembly is installed on the aircraft, and the repair of parts affects the assembly progress of the aircraft.

[0004] When installing the aileron clutch of the aircraft control system, the left square bracket and the right herringbone bracket of the aileron clutch are connected to the upper column of the wing rear beam and the frame edge of the fuselage structure with bolts, and the brackets on both sides of the aileron clutch are at a certain angle. During assembly, first complete the drilling and positioning of the connection hole between the left bracket of the aileron clutch and the wing rear beam, ensure that the gap between the right herringbone bracket of the aileron clutch and the fuselage skin is ≤0.2mm, and finally install bolts and nuts to complete the connection between the left square bracket and the right herringbone bracket of the aileron clutch.

[0005] At present, when installing the aileron clutch, the positioning hole drilled on the rear beam of the wing is connected to the initial bolt hole on the square bracket on the left side of the aileron clutch to complete the positioning of the aileron clutch on the rear beam of the wing. Check the gap between the bottom surface of the right side herringbone bracket of the aileron clutch and the fuselage skin. After the gap meets the requirement of ≤0.2mm, drill the bolt hole connecting the herringbone bracket and the fuselage skin. After fixing, drill the final bolt hole connecting the left side square bracket of the aileron clutch and the wing rear beam column. Due to the manufacturing error in the shape of the fuselage skin during the aircraft assembly process, when the aileron clutch and the rear beam column of the wing are positioned, the right side herringbone bracket and the fuselage skin are stuck, resulting in the non-concentric positioning holes on the left side square bracket of the aileron clutch and the rear beam column of the wing. At the same time, due to the structural form of the aileron clutch, the construction is difficult, which makes it more difficult to make holes between the left side square bracket of the aileron clutch and the rear beam column of the wing, and there is a problem of excessive hole diameter after the hole making is completed. Summary of the invention

The invention solves the problem that the left square bracket of the aileron clutch and the positioning hole on the wing rear beam column are not concentric due to the deviation of the fuselage skin shape when the aileron clutch of the aircraft control system is installed on the aircraft, and the construction conditions caused by the structural form of the aileron clutch are limited, resulting in an out-of-tolerance hole diameter after the hole is made between the left bracket of the aileron clutch and the wing rear beam column.

[0008] A new process method is provided, which eliminates the hole-making process of the left square bracket and the right herringbone bracket of the aileron clutch assembly during parts manufacturing, and eliminates the simple tooling for the assembly of the aileron clutch assembly to ensure the angle of the left square bracket and the right herringbone bracket. The assembly method is optimized, and the aileron clutch assembly is assembled on the aileron clutch hole-making device, and the tooling is used to control the relative angle between the square bracket and the herringbone. After the assembly is completed, the aileron clutch hole-making device is used to make holes, which solves the problems of the aileron clutch assembly being unable to be interchanged when it fails and the hole diameter being out of tolerance when connected by holes, as well as the angle error between the left square bracket and the right herringbone bracket of the aileron clutch assembly, and the uneven gap when installed on the aircraft.
