1、本科毕业论文(20届)车床主轴箱设计专业:机械设计制造及其自动化摘要车床是制造业中使用最广泛的一类机床,主要用来加工各种回转表面,如内外圆柱、圆锥表面、成形回转表面和回转体的端面,有些车床还能加工螺纹面。在各种车床中,卧式车床应用最普遍,工艺范围最广。其中作为主要的车削加工机床,CA6140机床广泛的应用于机械加工行业中,-49--49-适用于车削内外圆柱面,圆锥面及其它旋转面,车削各种公制、英制、模数和径节螺纹,并能进行钻孔,铰孔和拉油槽等工作。床身宽于一般车床,具有较高的刚度,导轨面经中频淬火,经久耐用。机床主轴孔径大,操作灵便
2、集中,溜板设有快移机构。机床结构刚度与传动刚度均比较高,功率利用率也比较高,适于强力高速切削。卧式机床的加工对象,主要是轴类零件和直径不太大的盘类零件,故采用卧式布局。其主要部件有:主轴箱、刀架、尾座、进给箱、溜板箱以及床身。本设计主要针对CA6140机床的主轴箱进行设计。机床主轴箱是一个比较复杂的传动部件。设计的内容主要包括确定机床的主要参数,拟定传动方案和传动系统图,计算和校核了主要零部件,并且利用专业制图软件对零件进行设计和处理。关键词;CA6140机床;主轴箱;传动AbstractThelathesithemostwidel
