Three-dimensional platforms are widely used in welding, mechanical processing, and workpiece inspection. Examples include: steel structures, various vehicle body manufacturing, bicycle and motorcycle production, construction machinery, frames and enclosures, pressure vessels, robotic welding, sheet metal processing, metal furniture, equipment assembly, industrial pipelines, and inspection systems.

The three-dimensional platform is a standardized, systematic, and universal fixture set, based on a workbench with five working surfaces featuring standardized grid holes and a front grid line. Equipped with various standard modules for positioning, it uses pins for connection to locate and clamp workpieces of various shapes. It also allows for random combination and repeated use in three-dimensional space, suitable for welding and assembly of multiple types of workpieces.
