Description

Technical Field

[0001] This invention belongs to the field of aircraft assembly and connection technology, and relates to a hole-making device and method for an aileron clutch. Background Technology

[0002] The aileron clutch of the aircraft control system consists of a square bracket on the left and a herringbone bracket on the right, connected by a connecting rod. The square bracket on the left has seven Φ6H8 connection holes to the wing rear spars column, and the herringbone bracket on the right has four Φ6H8 connection holes to the fuselage skin. The two brackets on either side of the aileron clutch are at a certain angle.

[0003] Currently, during the production of the aileron clutch assembly, the left square bracket is drilled with seven Φ4.5mm initial holes according to the dimensions specified on the drawings during part manufacturing. Similarly, the right A-frame bracket is drilled with four Φ4.5mm initial holes according to the dimensions specified on the drawings to connect with the fuselage skin. After the square and A-frame brackets are manufactured, they are connected by a central connecting rod, with simple tooling used to ensure the angle between the square and A-frame brackets. When installing the aileron clutch on the aircraft, it is positioned using the pre-drilled holes on the left square bracket and the positioning holes drilled on the wing rear spars according to the assembly jig. The gap between the bottom surface of the right A-frame bracket and the fuselage skin is checked. Once the gap meets the requirement of ≤0.2mm, bolt holes are drilled according to the four Φ4.5mm initial holes on the A-frame bracket to connect with the fuselage skin. Because the connecting holes on the aileron clutch assembly are drilled in the component state, errors occur during assembly. The relative positions of the connecting holes on the left square bracket and the right herringbone bracket cannot be accurately guaranteed. Therefore, when the aileron clutch assembly malfunctions and needs replacement, hole misalignment occurs, and the use of interchangeable holes results in out-of-tolerance hole diameters. Furthermore, the aileron clutch assembly lacks interchangeability for on-aircraft installation. Additionally, the angle between the left square bracket and the right herringbone bracket cannot be effectively controlled during assembly, leading to uneven clearance when the aileron clutch assembly is installed on-air, causing parts rework and impacting aircraft assembly progress.

[0004] When installing the aileron clutch on the aircraft control system, the left square bracket and the right herringbone bracket of the aileron clutch are bolted to the column on the wing rear spars and the fuselage structural frame, respectively. The two brackets of the aileron clutch are at a certain angle. During assembly, first, the drilling and positioning of the connection hole between the left aileron clutch bracket and the wing rear spars are completed, ensuring that the clearance between the right herringbone bracket of the aileron clutch and the fuselage skin is ≤0.2mm. Finally, bolts and nuts are installed to complete the connection between the left square bracket and the right herringbone bracket of the aileron clutch.

[0005] Currently, during aileron clutch installation, the positioning holes drilled on the wing rear spars are connected to the initial bolt holes on the left square bracket of the aileron clutch to complete its positioning on the wing rear spars. The clearance between the bottom surface of the right-side herringbone bracket of the aileron clutch and the fuselage skin is checked. After confirming the clearance is ≤0.2mm, bolt holes are drilled to connect the herringbone bracket to the fuselage skin. After fixing, final bolt holes are drilled to connect the left square bracket of the aileron clutch to the wing rear spars column. Due to manufacturing errors in the fuselage skin shape during aircraft assembly, the right herringbone bracket may become jammed against the fuselage skin during aileron clutch positioning with the wing rear spars column. This causes misalignment of the positioning holes on the left square bracket of the aileron clutch and the wing rear spars column. Furthermore, the structural limitations of the aileron clutch make construction difficult, increasing the difficulty of drilling holes on the left square bracket of the aileron clutch and the wing rear spars column, resulting in out-of-tolerance hole diameters after drilling. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of incompatibility during replacement of malfunctioning aileron clutch assemblies, excessive tolerance in hole diameter during connection, and uneven gaps during on-board installation due to angular errors between the left square bracket and the right V-shaped bracket of the aileron clutch assembly. It also addresses the issues of misalignment between the left square bracket of the aileron clutch and the positioning hole on the wing rear sparsor column caused by fuselage skin shape deviations during on-board installation, and the limitations imposed by the aileron clutch structure, leading to excessive tolerance in the hole diameter after drilling the connection hole between the left bracket and the wing rear sparsor column.

[0007] A hole-making device for an aileron clutch is provided. The hole-making device can effectively ensure the relative dimensions of the connecting holes on the left square bracket and the right herringbone bracket, and can effectively ensure the relative angle between the left square bracket and the right herringbone bracket of the aileron clutch assembly, thereby improving the assembly quality of the aileron clutch.

[0008] A novel manufacturing process is provided, eliminating the drilling steps for the left square bracket and right herringbone bracket of the aileron clutch assembly during parts manufacturing. It also eliminates the simple tooling used to ensure the angle between the left square bracket and the right herringbone bracket during assembly. The assembly method is optimized; the aileron clutch assembly is assembled on an aileron clutch drilling device, using tooling to control the relative angle between the square bracket and the herringbone bracket. After assembly, drilling is performed using the aileron clutch drilling device. This resolves the issues of incompatibility during replacement of faulty aileron clutch assemblies, excessive hole diameter in the connection, and uneven gaps during on-aircraft installation due to angular errors between the left square bracket and the right herringbone bracket.

[0009] A device and method for drilling holes for aileron clutch installation are provided. The device offers an open construction space, improving the assembly and installation quality of the aileron clutch and reducing construction difficulty. A new process method is also provided, eliminating the positioning hole on the left-side square bracket of the aileron clutch on the wing rear spars column, thus completely resolving the misalignment problem between the left-side square bracket of the aileron clutch and the positioning hole on the wing rear spars column caused by fuselage skin shape deviations.
