Abstract

The invention provides an airplane complex construction member numerical control processing tool standard locator automatically selecting method. Domain definition system and product joint position can be defined by calculation, and a candidate locator and an optimal locator are determined, so as to determine the type and specification of the standard locator meeting the locating requirement. The method can be applied to development of 'tool rapid generating sub system' standard locator automatically selecting program in the 'airplane complex construction member rapid numerical control processing ready system'. Tool design efficiency is improved, tool development and even the whole production ready period is shortened, and application benefit is favourable. Besides, the invention can be applied to automatic calling of airplane manufacturing tool and other special standard component. When applying the method, only manual selection of product joint and locator supporting surface is required, the standard locator can be automatically selected, automation, intellectualization and rapid design of locator can be realized, and design efficiency and quality of complex construction member numeric control processing tool is improved, thus shortening airplane development period.

Description

technical field [0001] The invention relates to an automatic selection method for a standard locator of numerically controlled machining tooling for aircraft complex components, which is used for the design and development of a CAD system for numerically controlled machining tooling, and belongs to the technical field of intelligent design of aircraft manufacturing tooling. Background technique [0002] In the field of aircraft manufacturing, positioners are used to ensure that the positioned workpiece is in a correct and reliable position, as well as the interchange of various components and the coordination of butt joints. With the substantial improvement of the level of my country's aircraft manufacturing industry, the application of complex components such as integral panels and bulkheads in modern aircraft structures has caused corresponding changes in the structure of aircraft CNC machining tooling. Due to its advantages of accurate positioning, space saving, convenien...
