AI Technical Summary
Existing interference inspection methods for hanging fixtures are complex and costly, and cannot be easily adapted to hanging fixtures, affecting their accuracy and safety.
A four-step inspection method is adopted, which involves determining the center of gravity of the tooling, importing a hemisphere with a diameter of N meters, moving the hemisphere to find the hanging intersection point, and rotating the inspection line around the axis to check for interference. This is simplified to four steps to check for interference at the hanging point.
It enables rapid and accurate interference inspection of hanging fixtures, reducing inspection time and costs, and improving the convenience and safety of inspection.

The beneficial effects of the present application are: the method can realize batch checking of the interference and gap between parts; the interference or gap distribution data between parts is presented; the checking report is batch output; the central display preview of the checking result is realized, and the work efficiency is greatly improved.
[0004] The prior art CN109719733A discloses a multi-arm robot mechanical arm interference analysis method. First, the LSS linear scanning ball model is used to envelope a complex spatial mechanical arm to simplify the mechanical arm. The simplified model of the mechanical arm includes three components, which are a cylindrical body in the middle part and two hemispherical bodies at the two ends. By solving and judging the effective interference points of each component at the interference time, it is judged that the LSS model is in the interference state, i.e. the mechanical arm is in interference. The interference analysis judgment criteria at any position are established, and the interference analysis algorithms between two cylindrical bodies, between a cylindrical body and a hemispherical body, and between two hemispherical bodies are obtained. The interference analysis method proposed in the present application can accurately judge the interference state between the mechanical arms.
