1、JIANGXIAGRICULTURALUNIVERSITY本科毕业论文(设计)题目:立式单轴木工镂铣机学院:工学院姓名:王冲学号:20100978专业:农业机械化及其自动化年级:农机101指导教师:林金龙职称:讲师二0一四年五月23摘要木工铣床-用高速旋转的铣刀(见木工刀具)将木料开槽、开榫和加工出成形面等的木工机床。木工铣床分为立式单轴木工铣床、木模铣床和镂铣机3种。立式单轴木工铣床(见图)的刀具装在从固定工作台伸出的垂直铣刀轴上,铣刀轴可倾斜和上下调整。工件紧贴固定工作台面和导板由手动送进,也可使
2、用导向辊和成形铣夹具进行侧面的成形铣削,还可将工件夹紧在活动工作台上加工榫头和端面。木模铣床的刀轴装在悬臂前部,可在垂直平面内转一角度。悬臂可在立柱上升降。工件夹紧在工作台上,可作纵向、横向和回转进给。木模铣床主要用于模型加工。镂铣机的刀具主轴转速很高(达2万转/分),工件和靠模(见仿形机床)重叠固定在夹具底板上。靠模绕工作台中心的定位销转动或移动时,铣刀即在工件上铣出相应的形状。工作台可升降和向前倾斜。20世纪70年代以后,数控(见数字控制机床)镂铣机发展很快,主要有转塔式和龙门式两种。前者的工作台
3、作纵向和横向移动,将刀具的转塔头作上下运动。后者的主轴作横向和上下运动,工作台作纵向运动。镂铣机主要用于板料雕刻和成形表面的铣削。23关键词:传动;齿轮;CADAbstractWoodworkingmilling-cutterrotating(seewoodworkingtool)willbewood,tenonandslotmachinewoodworkingmachineformingsurfaceetc..Woodworkingmillingmachineisdividedintovertica
