Intelligent positioning and processing method and system for seat framework based on laser welding

Abstract

The application discloses a seat framework intelligent positioning processing method and system based on laser welding, relates to the related field of laser processing, and comprises the following steps: mining a main stress transmission path of a seat framework based on a scene working condition, and constructing a digital load atlas; determining a limiting strategy by two-stage decision of clamping limiting and clamping preloading application according to a positioning intelligent agent and taking the digital load atlas as a reference; performing assembly clamping limiting of parts of the seat framework, scanning and converting to determine a weld three-dimensional coordinate, combining a welding intelligent agent to determine welding driving parameters, and performing automatic welding driving on a laser welding assembly. The application solves the technical problem that existing seat framework laser welding exists independent clamping positioning and welding process, which leads to misplacement of a clamping point and a force flow key point, and further affects welding precision and structural reliability, realizes collaborative optimization of clamping limiting and welding driving, and further improves the technical effect of welding precision and structural reliability.
