Flexible supporting and positioning system for docking of large airplane components

Abstract

The invention relates to a flexible supporting and positioning system for docking of large airplane components. The flexible supporting and positioning system comprises a nose supporting device, a flexible middle fuselage supporting device, a central wing supporting device and a flexible rear fuselage positioning and supporting device. Thus, the nose, the middle fuselage, the rear fuselage and central wings can be accurately and quickly docked, the flexible supporting and positioning system is reasonable, compact and safe in structural design, and innovative ideas and diversification of modern enterprise development are met. In addition, bearing data can be accurately measured by a weight sensor and are displayed via a display screen, so that operators can conveniently examine and operate an X-axis hand wheel and lead screw slide table and a Y-axis hand wheel and lead screw slide table to adjust load of flexible supports, flexible support positioners can coordinate safely and reliably in the X-axis and Y-axis directions, and moving accuracy of the large airplane parts and safety of the operators are guaranteed. Meanwhile, the flexible supports of the flexible middle fuselage support device can move towards the left and the right along transverse guide rails, and delivery of airplanes after final assembly is facilitated.

Description

technical field [0001] The invention belongs to the technical field of aircraft production, and in particular relates to a flexible support positioning system for docking large parts of an aircraft. Background technique [0002] The aircraft production process includes the docking of large parts, usually the nose, middle fuselage, rear fuselage and central wing parts; these large parts are all provided with docking interfaces (ie process joints), a total of 16. At present, the existing traditional docking of large aircraft parts in China mainly relies on tooling and process compensation to ensure the coordination of large parts. There is a margin in the docking parts, and the docking is carried out by hoisting and traction, and then finishing. This docking method Low precision, poor reliability, and easy occurrence of out-of-tolerance problems, resulting in irreversible horizontal measurement parameters; moreover, there are many measurement points, and the working platform o...

Problems solved by technology

At present, the existing traditional docking of large aircraft parts in China mainly relies on tooling and process compensation to ensure the coordination of large parts. There is a margin in the docking parts, and the docking is carried out by hoisting and traction, and then finishing. This docking method Low precision, poor reliability, and easy occurrence of out-of-tolerance problems, resulting in irreversible horizontal measurement parameters; moreover, there are many measurement points, and the working platform on the assembly line is relatively large. If the conventional layout method is adopted, the working ladder will be blocked. Setting measurement points will increase a lot. If the measurement target points are arranged on the ground, it will affect the passage of staff and equipment on the road, which will inevitably cause contact and stumbling, which not only poses safety hazards, but also causes a decrease in accuracy. High precision, safe and convenient with pre-embedded structure
