1、CA6140普通车床床头1轴轴承座夹具设计全套CA图纸,PROE图纸,动画等,联系153893706摘要车类机床主要用于加工各种回转表面,如内外圆柱表面、圆锥表面、成型回转表面和回转体的端面等,有些车床还能加工螺纹面。由于多数机器零件具有回转表面,车床的通用性又较广,因此在机器制造厂中,车床的应用极为广泛,在金属切削床中所占的比重最大,约占机床总台数的20%~35%。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,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
2、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进行了零件的设计和处理。关键词:CA6140机床零件传
