Assembling clamp for carbon fiber composite aircraft cabin door

Abstract

The invention provides an assembling clamp for a carbon fiber composite aircraft cabin door. The assemble assembling clamp has the function of assembling five metal joints on the composite cabin doorthrough a riveting bonding mode, and the outline precision of the tooth-shaped edge relative to five joint holes, and the relative position degree and the coaxial degree among the joint holes are ensured. Through the assembling clamp, high precision assembling of the carbon fiber composite cabin door and the metal joints can be achieved, relative position deviation caused by the unreasonable positioning and clamping mode or the rebound and super poor precision of a manufactured piece caused by large state deviation between the state of the manufactured workpiece and the state after the manufactured workpiece is removed from a frame during assembling is avoided, meanwhile, the mode of a frame-type structure combined positioning assembly has the enough openness, the operation space can be ensured, the structure can be simplified as far as possible, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to an assembly fixture for a carbon fiber composite material aircraft cabin door. Background technique [0002] Because of its performance (specific strength, specific modulus, heat resistance and toughness, etc.), carbon fiber composite materials are not only much higher than commonly used structural materials such as steel and aluminum, but also superior to glass fiber reinforced plastics, and are also widely used in the aviation field. Such as aircraft door, fairing, central wing box section, etc. Among them, the aircraft door is usually a complex curved surface, and there are many parts that cooperate with the airframe, and it is the last part of the final assembly, and its assembly accuracy is often much higher than other parts, so Therefore, the rational design of the carbon fiber composite assembly fixture is the most important thing in determining the manufacture of the entire hatch part. At present, this type of assembly...

AI Technical Summary

Problems solved by technology

At present, this type of assembly fixture mainly follows the assembly form of the original metal hatch parts, ignoring the springback of carbon fiber composite parts, so that the precision of the assembled parts is often out of tolerance, and the final assembly is difficult to coordinate.

This not only increases the development cost, but also seriously affects the project schedule
