Abstract

A multi-vehicle type co-production line flexible framing is disclosed, comprising a robot welding system, a high speed transport system, a floor panel intelligent flexible positioning system, and a side panel flexible positioning and switching system. The floor panel intelligent flexible positioning system is correspondingly connected to a transfer rail of the high speed transport system. The side panel flexible positioning and switching system comprises a side panel fixture consolidation system, a fixture storage system, and a fixture switching and rail system. The side panel fixture consolidation system corresponds to the side of the floor panel intelligent flexible positioning system. The fixture storage system is arranged on two sides of the side panel fixture consolidation system in the transfer direction of the high speed transport system. The fixture switching and rail system is connected between the side panel fixture consolidation system and the fixture storage system. The improved structure is relatively compact and practical, has a short switching time, a high production efficiency, and a small floor area, and may use a large number of welding robots, fully satisfying the capacity requirement of 60JPH of the automobile factory.

Claims
