Description

technical field [0001] The invention relates to a flexible automatic bracket mechanism used in conjunction with a rolling machine, in particular to a flexible automatic bracket device attached to a rolling machine for large thin-walled parts 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 outsid...

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.

Furthermore, because some large thin-walled parts cannot be processed and formed at one time due to the limitations of material characteristics and processing technology during rolling, they need to be processed many times to gradually obtain the final forming surface

In the intermediate state of processing, the curved surface presents different curvature forms, and brackets with different curvature configurations are required for protective support. However, the flat surface shape of some simple brackets does not meet the above processing requirements.

Moreover, the quality and size of the large thin plate parts are very large. After the processing, it is very inconvenient to manually remove them from the bracket and then move them to the next station, and it may cause irreversible damage to the workpiece due to human factors. A convenient, labor-saving and safe delivery device
