摘　　要：防错是汽车生产中提升生产效率、防止设备不必要损失及减少不合格品产生的重要手段。发动机工厂曲轴线加工中心在夹具换型时,涉及到一些硬件的切换,切换过程由人工控制,存在因硬件使用错误导致的刀具、主轴、零件、换型硬件干涉风险。该风险可能造成严重后果:如主轴及刀具损坏、工件报废等。本文提出了一种加工中心换型防错装置,利用光电传感器信号数据和逻辑程序,判断换型硬件是否存在使用错误,从根本上规避干涉风险。Error proofing is an important means to improve efficiency,prevent equipment loss and reduce unqualified products in automobile production.Sometimes we need to change some hardware when crankshaft line CNC fi xture type changing,this process is manual controled and has risk of tool/spindle/parts/Fixture interference,which will cause serious consequences.This paper presents a kind of error proofi ng device for type changing, which can judge whether there is use error of changing hardware by using photoelectric sensor signal data and logic program, so as to avoid interference risk fundamentally.
