1、毕业设计说明书刀具刃磨中心Z轴进给系统设计与建模[摘要]本文主要阐述了刀具刃磨中心工具磨床Z轴进给系统设计与建模,数控磨床是利用磨具对工件表面进行磨削加工的机床,是高效高精度的刀具刃磨机床,特别是五轴联动的数控工具磨床,是刀具刃磨机床发展的方向。可以用来加车刀,麻花钻,工立铣刀,球头铣刀,阶梯钻,铰刀,成形铣刀,深孔钻,三角凿刀和牛头刨刀具等。进给系统采用全封闭结构,无外挂装置,内置切削液冷却循环装置及油雾回收装置。进给轴由单元电机通过高精度无间隙联轴器与精密滚珠丝杠副直联,无间隙误差。且运动平稳,传动精度高,不易磨损,使用寿命长。导轨全
2、部采用燕尾型精密滚珠直线导轨,具有精密高,摩擦系数小,寿命长等特点。导轨、滚珠丝杠副采用具有冷却装置的全自动定时定量润滑系统。并在PROE中画出Z轴进给系统三维模型图,生成二维工程图。[关键词]刃磨中心Z轴进给系统闭环系统滚珠丝杠直线型滚动导轨WithgrindingcenterZaxisfeedsystemdesignandmodelingJiangPengFei(Grade08,Class1,MajorMechanicaldesignandmanufactureofextremelyautomation,MechanicalEngin
