Description

Technical Field

[0001] The utility model belongs to the technical field of aircraft skin processing technology, and in particular relates to a skin processing and measuring integrated machine. Background Art

[0002] The skin parts that constitute the aerodynamic shape of the aircraft have the characteristics of complex shape, large size, and relatively weak rigidity. The processing technology is quite difficult. The mirror milling process is currently a relatively mainstream method in the existing skin milling process. The mirror milling process specifically uses the mirror-arranged tool and the top support device to move together on the skin blank and mill out the designed shape of the skin. Since the movement of the tool will cause the skin material to deform and rebound, it will have an adverse effect on the processing accuracy. In order to ensure the processing quality, it is necessary to repeatedly perform multiple measurements during the processing and before and after the processing. At present, the traditional physical comparison appearance detection method is still mainly used at home and abroad. The skin parts are placed and positioned on the inspection mold tire, and the gap error between the skin and the mold tire is measured by tools such as calipers and feelers. For some parts that are difficult to implement with tools, it can only be observed by vision whether it coincides with the mold tire engraving line, and by touch to perceive whether it fits the mold tire. This physical comparison detection method consumes manpower, has low detection accuracy, and the parts that can be detected are not comprehensive enough, which cannot meet the requirements of modern aircraft manufacturing for fast and high-precision detection. Although some measurement methods using 3D scanning equipment can provide better accuracy, additional scanning equipment inevitably increases equipment investment. Therefore, how to organically integrate automated processing and measurement functions in skin manufacturing equipment to improve skin processing efficiency and reduce manpower and material costs is a technical problem that urgently needs to be solved in this field.
