摘　　要：为保证液压挖掘机支重轮座的安装面及销孔的位置精度要求,在立式加工中心进行加工,并设计多工位液压夹具。加工过程中,多工位液压夹具的液压夹紧力一方面对工件起轴向夹紧作用,另一方面防止工件旋转。通过计算切削力,求得夹具所需的液压夹紧力,并以此为基础对夹具进行设计。实际应用证明,所设计的多工位液压夹具能够有效保证支重轮座铣削和钻削的高精加工。How to design a chuck to machine track rollers.In order to ensure positional precise requirements in fitting face and pin hole of hydraulic excavator's track rollers which requires redesign of a hydraulic multi-position chuck for a vertical machining cell to machine such work pieces,in order to clamp tight the part on one hand and prevent it from turning on the other hand.A right clamping force was computed out before the redesign.Actual application has proved that the redesigned hydraulic chuck can effectively ensure high-precision machining of the track roller.
