摘　　要：为提高刀剪专用数控磨床主运动速度,改善主运动传动机构,提出设计一种刀剪专用数控磨床主轴副。具体方法是:用支座及筒套代替传统用的主轴箱,主轴副直接装于筒套上,采用前后两点支承,用弹簧调整运动间隙,此方法结构简单、传动链短、支座及筒套加工工艺性好。该主轴副转速可达4 500 r/min,集传统主轴和电主轴的优点,克服了传统主轴系统的低转速、低几何精度及电主轴价格昂贵等缺点,满足了刀剪专用数控磨床的磨刀速度要求。To increase the rotation rate of numerical control grinder applied to scissors and improve the transmission mechanism, a special spindle unit of CNC scissors grinder is designed. The details are as follows： The traditional headstock is replaced by a cradle and cylinder sleeve; the spindle unit is directly installed on the spindle cylinder sleeve; a spring is employed to adjust the movement gap. The design is of simple structure and short transmission chain, with good processing performance. the rotation rate of the spindle unit can reach 4500r/ min.
