Abstract: By analyzing the current situation of rear suspension assembly of heavy engineering vehicle, a set of automatic tightening system for rear suspension assembly is designed and manufactured according to input of process design. The tightening system adopts high-precision flexible displacement sub assembly station, high-precision servo rotation interactive platform, digital information production technology, which can realize robot automatic tightening assembly through 3D visual identification camera and positioning technology. This system solves the knotty problem of rear suspension assembly, and it is stable, reliable and practical.

Key words: Displacement sub assembly station, 3D vision recognition system, Robot tightening

1 前言

目前,重型載貨汽車后懸架U型螺栓大多采用上穿的裝配方式,以解決由于使用工況惡劣導致板簧松動、U形螺栓斷裂的問題,同時也造成了車輛維修時后懸架板簧更換困難。(剩余8898字)
