Abstract

The invention belongs to the technical field of aerospace manufacturing, and particularly relates to a composite material opening structure machining tool and method. The tool comprises a plurality ofsets of supporting frame structures, a base structure and a base platform, wherein the base platform is arranged at the upper end of the base structure; the multiple sets of supporting frame structures are sequentially arranged on the base structure to form a working face of the tool; a plurality of groups of vacuum adsorption systems are arranged on the work face, and each vacuum adsorption system comprises an air suction hole, a vacuum groove and a sealing groove; and the vacuum groove is arranged at the upper end of the corresponding supporting frame structure, the air suction hole is formed in the center of the groove bottom of the vacuum groove, and the sealing groove is formed in the peripheral edge of the vacuum groove. The opening structure of a composite material is adsorbed andfixed through the independent vacuum adsorption systems on the supporting frame structures. Phenomena of broaching, tool bouncing and the like caused by slippage in the part machining process are avoided, and the machining precision of the structure is improved.

Description

technical field [0001] The invention belongs to the technical field of aerospace manufacturing, and in particular relates to a composite material opening structure processing tool and processing method. Background technique [0002] Aerospace composite materials have many openings and complex profiles, and are generally thin-walled structures with low rigidity. They also have solidification deformation. During CNC machining, the parts need to be fixed firmly to prevent the parts from deforming during processing. , slipping, causing broaching and springing of knives, resulting in out-of-tolerance or scrapping of parts. [0003] Fixtures are mostly used in existing CNC machining fixing methods. It is easy to cause the layering of composite materials, and for the opening area, the design of the clamping device is relatively complicated. The processing process may require multiple replacements, the processing quality cannot be guaranteed, and the processing efficiency is low, r...
