Description

浮动接头
技术领域
本发明涉及一种接头,特别是一种浮动接头,用于镗削机床的镗杆与主轴之间的连接。
背景技术
镗削机床包括主轴,主轴与安装刀具的镗杆端头固定连接,主轴转动时,镗杆带动刀具一起转动,刀具对工件进行镗削。这种结构的镗杆连接方式属于刚性连接,加工时,镗杆很容易出现不必要的应力,影响加工精度和加工质量。
发明内容
本发明的目提供一种结构简单、镗杆相对于主轴有一定量径向间隙、镗杆保持浮动状态、提高加工精度的加工质量的浮动接头,克服现有技术的不足。
本发明的浮动接头,包括接头体,在接头体的外侧套装有套体,套体与接头体之间设有轴向限位件和防止相对转动的限位件,套体与接头体之间有径向间隙,套体的侧面与镗杆端头固定连接。
所述的轴向限位件是在接头体的端头固定连接有压盖,压盖压在套体上;所述的防止相对转动的限位件是在接头体上套装有过渡盘,接头体端头的边沿侧面固定有第一连接键,第一连接键刚好位于过渡盘周边上的键槽内,过渡盘的侧面与套体的端面之间设有第三连接键。
本发明的浮动接头,安装时,镗杆端头与套体固定连接,接头体与镗床主轴端头固定连接,套体相对于接头体有径向间隙,主轴带动镗杆转动时镗杆相对于接头体(主轴)有一定量的浮动,可消除镗杆可能出现的应力,明显提高了工件的加工精度,提高了加工质量,延长了使用寿命,整体结构简单。
附图说明
图1是本发明具体实施方式的结构示意图。
具体实施方式
如图1所示:1为接头体,在接头体1的外侧套装有套体4,套体4与接头体1之间设有轴向限位件和防止相对转动的限位件,套体4与接头体1之间有径向间隙16,套体4的侧面与镗杆8端头通过第二螺栓5固定连接。在套体4与镗杆8端头之间设有第二连接键9,第二连接键9通过第四螺栓10与套体4的端面固定连接。
上述的轴向限位件是在接头体1的端头通过第三螺栓7固定连接有压盖6,压盖6压在套体4上,压盖6刚好位于套体4中心部位的止口槽内。
上述的防止相对转动的限位件是在接头体1上套装有过渡盘13,过渡盘13与接头体1之间有第二间隙17。接头体1端头的边沿18侧面通过第一螺栓2固定有第一连接键3,第一连接键3刚好位于过渡盘13周边上的键槽内,过渡盘13的侧面与套体4的端面之间设有第三连接键12。
在接头体1内孔处设有与供冷却介质装置相接的冷却管11,冷却管11与接头体1之间有第一间隙15。工作时,可通过供冷却介质装置向冷却管11内供冷却介质,冷却介质通过冷却管11流向前端的镗杆8中心孔内,对刀具进行冷却。
安装时,镗杆8端头与套体4固定连接,接头体1与镗床主轴端头通过第止螺栓14固定连接,套体4相对于接头体4有径向间隙,主轴带动接头体1转动,接头体1依次带动第一连接键3、过渡盘13、第三连接键12、套体4、第二连接键9、镗杆8转动,镗杆8转动时相对于接头体1(主轴)有一定量的径向浮动,可消除镗杆8可能出现的应力,明显提高了工件的加工精度,提高了加工质量,延长了使用寿命,整体结构简单。
