Pose Simulation Matching Method for Dimensional Positioning Based on Two Three-coordinate Locators

Abstract

The invention discloses a three-dimensional positioning pose simulation matching method based on two three-coordinate locators, which calibrates the zero point position, the active receiving position and the driven receiving position of the active locator and the driven locator, and then the active locator is equivalent As a five-axis machine tool model, the driven positioner is equivalent to a three-axis machine tool model, and the translation parameters of the five-axis machine tool model are obtained by solving the relationship between the translation pose and the rotation pose between the zero position and the active receiving position and rotation parameters; by solving the translation pose relationship between the zero position and the driven receiving position, the translation parameters of the three-axis machine tool model are obtained; and then the simulation movement of the dimensional positioning tool is converted into the translation and rotation of the five-axis machine tool model And the translation of the three-axis machine tool model, so that the simulation environment of the dimensional positioning tool is consistent with the actual environment, and realizes the automatic matching of the dimensional positioning tool and the locator in the simulation environment.

Description

technical field [0001] The invention belongs to the technical field of aircraft component pose adjustment simulation, and in particular relates to a dimensional positioning pose simulation matching method based on two three-coordinate locators. Background technique [0002] In recent years, the concept of developing digital assembly has become more and more popular. During the digital assembly process of an aircraft, the interconnected parts, assemblies and components must maintain the correct position and attitude, so their support method is very critical. Considering the pose adjustment requirements of aircraft components and components, it is usually supported by a pose adjustment unit composed of at least two three-coordinate numerical control positioners. However, the attitudes of each aircraft are inconsistent, resulting in changes in the position of the actual locator. In order to ensure the safety of the CNC machining program running in the subsequent automatic hole...

Problems solved by technology

However, the attitudes of each aircraft are inconsistent, resulting in changes in the position of the actual locator. In order to ensure the safety of the CNC machining program running in the subsequent automatic hole-making process, it is necessary to establish a simulation that is consistent with the actual hole-making machine tool. The environment is exactly the same as the simulation environment to ensure the authenticity of the simulation environment. Therefore, each product must configure the simulation environment according to the actual location of the locator and the dimension frame. Due to the complicated steps of configuring the environment, and there are many components that need to be configured. , therefore, error-prone during the configuration process and is not conducive to the promotion of simulation applications

At the same time, in the actual environment, the driven end of the dimensional positioning tool can follow the movement of the active end, but in the simulation software, the driven end of the dimensional positioning tool cannot follow the active end. The simulation of type positioning tooling brings problems that do not match the actual environment
