Abstract

The invention provides a vacuum absorption numerical control floating lattice bracket. The bracket comprises a working table (1) and a plurality of floating bracket units (3) installed on the working table. The bracket is characterized in that the floating bracket units (3) are arranged on the working table (1) in a rectangular array mode, and supporting legs (24) are arranged on the working table (1); a positioning device used for positioning a structural member (2) is fixed to the working table, and the original point of the structural member (2) in CAM software is determined through the positioning device; according to the original point and the curved surface shape of the structural member (2), the CAM software in a numerical control system calculates the height of each floating bracket unit (3), according to the data calculated by the CAM software, the numerical control system drives spherical surface supporting points in the floating bracket units (3) to form the floating lattice bracket coincident with the curved surface of the structural member, and the structural member (2) is placed on the floating lattice bracket according to a set position and absorbed, so that the positioning and fixing of the structural member are completed. The vacuum absorption numerical control floating lattice bracket is simple in structure, convenient to position, high in universality and capable of meeting positioning requirements of structural members in various shapes, improving the positioning efficiency and reducing the machining cost.

Description

technical field [0001] The invention relates to a part positioning and clamping technology, in particular to a clamping and positioning device for special-shaped parts, in particular to a vacuum adsorption numerical control floating lattice bracket for processing similar aircraft parts. Background technique [0002] With the continuous development of my country's aerospace industry, high-strength composite lightweight materials such as carbon fiber have been more and more widely used. Among them, components such as aircraft wings and empennages are also widely made of carbon fiber composite materials. The characteristics of such large components It has a complex shape and surface, large size, and relatively weak member rigidity. For a long time, the processing and manufacturing of aircraft components has mainly used rigid mold positioning. This method has the characteristics of convenient use, high production efficiency, and good size consistency of parts, which can meet the ...
