Embodiment Construction

[0031] Method example:

[0032](1) Under the CATIA software environment, read in the 3D model information of the upper left panel of a certain type of wing and the model information of a certain bracket type automatic drilling and riveting system, position the panel model on the model of the automatic drilling and riveting system, and measure Theoretical travel of each degree of freedom of each tooling positioning point, for each stringer, a number of pre-positioning holes are evenly distributed according to the length of the stringer, and several key feature points are selected from the pre-selected positions of the pre-positioning holes to represent its pose respectively, and the key The theoretical coordinates of the feature points represent the theoretical pose of the stringers; for the skin, the pre-positioning holes are arranged according to the positions of the pre-positioning holes of the stringers, and several key feature points are selected from the pre-selected posit...

Abstract

The invention discloses a multipoint flexible positioning method and tool for automatic drilling and riveting assembly of a wallboard. The method comprises the steps of: positioning a long truss and a skin which constitute the wallboard on an automatic drilling and riveting system tool, adjusting poses of the long truss and the skin through adjusting each degree of freedom of the positioning tooland then making pre-positioning holes for connecting the long truss and the skin; dismounting the skin, carrying out deburring and chipping removing on the pre-positioning holes in the long truss andthe skin and coating flue in the gaps between the long truss and the skin; positioning the skin again and arranging pre-positioning nails in the pre-positioning holes; dismounting the pre-positioningnails one by one while riveting rivets one by one in the pre-positioning holes and then dismounting the wallboard in the multipoint flexible positioning tool. By means of the method and tool which are disclosed by the invention, the flexible adjustment of positioning points is realized; a special tool is not needed; the assembly period is shortened; the tool cost is saved; the assembly requirements of different types of wallboards can be rapidly responded; the assembly efficiency can be obviously increased; and the higher automaticity and assembly accuracy are provided.

Description

technical field [0001] The invention belongs to the technical field of automatic drilling and riveting assembly of aircraft wall panels, and relates to a positioning method and tooling for automatic drilling and riveting assembly of aircraft wall panels. Background technique [0002] The automatic drilling and riveting assembly technology of wall panels is one of the most advanced assembly and connection technologies. It has the characteristics of good drilling and riveting quality, high production efficiency, and good working conditions. It is widely used in the drilling and riveting assembly of wall panels. During the drilling and riveting assembly process of aircraft siding, there are often two assembly processes of pre-connection and drilling riveting. Among them, the pre-connection process is mainly to connect the long stringer and the skin with the pre-positioning nails on the pre-positioning tooling to form the initial wall panel. Due to the various shapes and comple...
