Description

Technical field [0001] The invention relates to the field of advanced aerospace manufacturing, in particular to an integral riveting device and a method for large-scale cylindrical members. Background technique [0002] The aircraft cabins such as the rocket body section of the carrier rocket and the aircraft fuselage shell are riveted by two parts of large complex thin-walled plate and shell parts and a truss structure. The characteristics of plate and shell thin-walled parts are large curved surfaces, thin-walled low rigidity, and complex structure. These characteristics cause difficulties in positioning and clamping during processing, complex processing techniques, long processing times, and large equipment required. [0003] The traditional riveting of aircraft cabin body adopts manual drilling and riveting, etc., which has the following shortcomings: 1. The manual drilling and riveting efficiency is low and the processing cycle is long. Before manual riveting, multiple proce...

AI Technical Summary

Problems solved by technology

Thin-walled parts of plates and shells are characterized by large curved surfaces, thin-walled low rigidity, and complex structures. These characteristics make positioning and clamping difficult during processing, complex processing technology, long processing time, and huge equipment required.

[0003]Traditional aircraft cabin riveting adopts manual drilling and riveting, piece riveting, etc., which has the following disadvantages: 1. Manual drilling and riveting has low efficiency and long processing cycle

Manual riveting cannot meet the continuity of a series of processes such as positioning, clamping, drilling, nail feeding, riveting, and error correction; piecewise riveting is required in the process of piecewise installation and riveting of thin-walled parts. , The whole section of the cabin is positioned, clamped, and error corrected, which to a certain extent has caused the repetition and separation of the process, prolonging the production cycle, increasing the difficulty of manufacturing, and making it difficult to meet the accuracy requirements

3. The weak rigidity of the workpiece during processing

The rigidity of large thin-walled parts is low, and the deformation is large during processing. Traditional manual drilling and riveting and split riveting are partial riveting, so it is difficult to control the overall deformation of the workpiece well.
