The bracket device of the large-sized thin-wall airplane covering component rolling machine comprises an upper executing framework device of the bracket device, a lower supporting framework device of the bracket device, a rough executing device regulating structure, a rolling combined mechanism and a light-collecting and distance-measuring device, wherein the upper executing framework device of the bracket device is connected with the lower supporting framework device of the bracket device; the rough executing device regulating structure is connected with the upper executing framework device of the bracket device and the lower supporting framework device of the bracket device through shaft hole fit respectively; the rolling combined mechanism is distributed on the upper executing framework device of the bracket device; and the light-collecting and distance-measuring device is installed on the upper executing framework device of the bracket device. The bracket device of the large-sized thin-wall airplane covering component rolling machine can protect and support a rolled finished product of a large-sized thin-wall airplane component more safely and reliably, can perform corresponding regulation according to free-form surfaces of different workpieces, and has relatively high flexibility and strong adaptability, so that a supporting structure can be adhered to a curved surface better and the unnecessary damage to the workpieces can be avoided.

Description

technical field [0001] The invention relates to a bracket mechanism used in a rolling machine, in particular to a bracket device for a rolling machine of a large thin-walled covering part of an aircraft. Background technique [0002] At present, the international and domestic aviation industry is developing unprecedentedly, the diversification trend of aircraft types is obvious, and the performance of aircraft is constantly improving. As a result, the requirements for the aircraft manufacturing industry and upstream industries have also been continuously improved, such as manufacturing accuracy, delivery speed, cost control and so on. The structure of the aircraft is very complex. Its outer covering is a large thin-walled part. Its function is to maintain the shape of the aircraft and make the aircraft have good aerodynamic characteristics. On the surface, the force is complex, and it is in direct contact with the outside world, so it not only requires high strength and goo...

AI Technical Summary

Problems solved by technology

[0003] After investigation, most of the domestic rolling machines that manufacture such large thin-walled parts do not have corresponding auxiliary bracket equipment, and only rely on multiple manual delivery and receiving of plate parts; or there are only very simple brackets, and the functions are not perfect.

In this way, the processed thin-walled parts may be affected by their own gravity and have unnecessary and unpredictable deformation during the processing process, which may cause damage to the internal mechanical properties of the structure, and have unpredictable effects on service performance and aerodynamic performance.

Although there are some special brackets in the world, the supporting part is a flat plate structure with adjustable angle, which cannot adapt to various curved surface shapes, and the protection and support effect is not very good.
