High-frequency impact treatment method for aluminum honeycomb cell end faces

Abstract

The invention discloses a high-frequency impact treatment method for aluminum honeycomb cell end faces. The high-frequency impact treatment method for the aluminum honeycomb cell end faces is characterized by comprising the following steps that S1, a to-be-treated aluminum honeycomb is fixed, and to-be-treated aluminum honeycomb cell end faces are upward; S2, the initial relative positions betweena high-frequency impact tool and the to-be-treated aluminum honeycomb cell end faces are determined, and the machining path is determined; and S3, the high-frequency impact tool moves along the movement path and conducts high-frequency impact treatment on the to-be-treated aluminum honeycomb cell end faces on the movement path, and the aluminum honeycomb cell end faces undergoing high-frequency impact treatment are obtained. According to the aluminum honeycomb treated by the adoption of the high-frequency impact treatment method, the cell end face area is increased, the width of the honeycombwalls near the end faces are increased, the effective adhesion binding area is increased, the adhesion binding strength is improved, and then the mechanical performance of an aluminum honeycomb structural component is improved. In addition, the high-frequency impact treatment method for the aluminum honeycomb cell end faces has the advantages of being high in adhesion strength controllability, clean and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of processing, in particular to a high-frequency impact treatment method for the end faces of aluminum honeycomb cells. Background technique [0002] At present, sandwich structures made of aluminum honeycomb are widely used in the aerospace field, such as satellite fairings, aircraft doors, floors, etc. The manufacturing process of the sandwich structure mainly includes: processing the aluminum honeycomb according to the design requirements of different shapes; After melting, the glue flows to the cell ends and side walls of the aluminum honeycomb; finally the glue solidifies and the bonding is completed. Because the bonding quality of the aluminum honeycomb and the skin has a great influence on the performance of the sandwich structure, and the wall thickness of the aluminum honeycomb is mostly 0.03mm to 0.1mm, the effective bonding area of ​​the end surface of the aluminum honeycomb cell only accounts fo...
