Embodiment approach

[0017] The example of the invention uses Visual C++ as a development tool to realize a method for fast retrieval of connectors on a CATIA platform.

[0018] figure 1 In order to quickly retrieve the connection piece information flow chart, the specific implementation steps of the fast retrieval connection piece information proposed by the present invention are as follows:

[0019] Step S1, select the part to be retrieved and the R digital model. The part to be retrieved is the object of the operation, and the R digital model is the position of the normal vector and the corresponding standard part name and other information, such as figure 2 As shown, the skin 1 is connected with three parts 2 connected to the skin. The position of the standard part used for the connection is the normal vector 3 in the R model. The type, name and other information of the standard part are explained in the R model. Due to the large number and variety of parts on the aircraft, it is several ti...

Abstract

The present invention relates to a part connection information retrieval method, comprising the following steps, step S1, select the part to be retrieved and the R digital model; S2, the intersection operation of the normal vector in the R digital model and the selected part; S3, traverse and extract all parts in the product ; S4, intersecting the screened normal vectors with all the parts; S5, sorting out the result data and outputting them according to the format. This method can quickly calculate and analyze the information connected with the selected part, including: the name of the connected part, the name of the standard part corresponding to the connected part, the quantity of the standard part, etc. The realization of the method makes the aircraft production process more concise and quick, and effectively shortens the production cycle of the aircraft.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for retrieving connection information of part models in a digital manufacturing process. Background technique [0002] In the field of aircraft manufacturing, digital manufacturing has gradually replaced the traditional manufacturing method of analog quantity transfer based on standard tooling. The manufacturing basis in digital manufacturing is the engineering data sets provided by the design department, and the digital models in these engineering data sets mainly reflect the geometric information and process information of the parts. On the digital model of a special part node (partnote), information such as standard parts and locations used for connection between parts are stored. For example, the production department of an enterprise requires the digital model to give the connection information of the parts, including the connected parts and the standard used. pa...
