Description

Technical Field

[0001] The invention relates to an open degree adjustment and fixing system for an open special-shaped protective layer and a use method thereof, and belongs to the technical field of industrial automation production. Background Art

[0002] With the continuous development of high-speed aircraft, the surface insulation process of special-shaped aircraft has become an important part affecting the flight performance of high-speed aircraft. Therefore, the bonding and assembly of aircraft cabin sections and protective layers have gradually formed a new field of automated scraping and assembly at home and abroad. The processing and fixation of special-shaped protective layers are key links in the assembly of aircraft protective layers. Special-shaped protective layers usually have asymmetric, multi-curved or irregular geometric features. The precise adjustment of their openness and reliable fixation directly affect the product assembly quality and subsequent process effects.

[0003] In traditional technology, such operations mostly rely on manual intervention or simple mechanical fixtures, which have significant limitations: on the one hand, manual adjustment of the opening degree depends on the operator's experience and is easily affected by subjective factors, resulting in low precision, poor repeatability, and difficulty in meeting mass production needs; on the other hand, conventional fixtures are difficult to adapt to the dynamic adjustment needs of special-shaped structures due to their high structural rigidity and insufficient degrees of freedom, which can easily cause local stress concentration or deformation damage to the protective layer. In addition, although existing automated equipment can achieve basic positioning, it generally lacks multi-dimensional collaborative positioning and real-time feedback mechanisms, resulting in insufficient coupling control accuracy between the opening degree adjustment and the axial positioning, and slippage or overpressure problems are prone to occur during the fixing process, affecting product consistency and yield rate.

[0004] The existing technology has not yet proposed an efficient solution to the above problems. For example, the existing technology uses a single-dimensional mechanical limit device, which can achieve basic fixation, but cannot dynamically adapt to the change in the openness of the special-shaped protective layer. This makes it easy for relative positioning errors between the cabin section and the protective layer to occur during the connection process of different special-shaped protective layers, resulting in low connection accuracy, connection misalignment or excess glue extrusion, resulting in product scrapping or glue waste.

[0005] In summary, the existing adjustment and fixing devices have the technical problem of insufficient control accuracy for special-shaped protective layers. Summary of the invention
