Description

钻床快换夹具
技术领域
本发明涉及机械辅助装置领域,具体涉及钻床快换夹具。 
背景技术
在钻床的刀具装夹方式中,一般都采用钻床主轴内锥孔与刀柄(或过渡套)的外锥面相配合的结构。在更换刀具时,需要先将楔铁插入钻床主轴上的拆卸孔里,再用榔头敲击楔铁方可拆下刀具。当加工一个具有多种规格孔的零件时,频繁地更换刀具将会伴随整个加工过程。而且使用榔头敲击楔铁更换刀具的方式既费时费力又产生噪音。且生产效率低,劳动强度大。 
发明内容
为了解决上述问题,本发明提供一种结构简单,更换迅速,能避免刀具损伤,且可靠度高的钻床快换夹具。 
本发明钻床快换夹具,包括快换主体,所述快换主体两端为锥柄状,一端开有一凹槽,凹槽壁上设置有两个钢珠孔,所述快换主体上套接有一锁紧套,所述锁紧套上开有一锥孔,锥孔内安装有两个钢珠,所述快换主体凹槽中安装有快换杆,快换杆的一端开有用于安装刀具的锥孔,另一端开有锁紧槽,所述快换杆上还设置有一拆卸孔,所述拆卸孔的轴线与快换杆的轴线相垂直。 
优选地,快换主体中部开有一凹槽,所述凹槽中设置有弹簧挡圈。 
优选地,锁紧套外圆周面上压有滚花。 
本发明结构简单,更换迅速,能避免刀具损伤,且可靠度高。 
附图说明
图1为钻床快换夹具结构示意图。 
图2为快换杆结构示意图。 
附图标记:1-钻床主轴,2-快换主体,3-弹簧挡圈,4-锁紧套,5-钢珠,6-快换杆,7-钻夹头,8-刀具,9-拆卸孔,10-锁紧槽。 
具体实施方式
本发明钻床快换夹具,包括快换主体2,所述快换主体2两端为锥柄状,一端安装在钻床主轴1上,另一端开有一凹槽,凹槽壁上设置有两个钢珠孔,所述快换主体2上套接有一锁紧套4,所述锁紧套4上开有一锥孔,锥孔内安装有两个钢珠5,所述快换主体2凹槽中安装有快换杆6,快换杆6的一端开有用于安装刀具8的锥孔,另一端开有锁紧槽10,所述快换杆6上还设置有一拆卸孔9,所述拆卸孔9的轴线与快换杆6的轴线相垂直,快换主2中部开有一凹槽,所述凹槽中设置有弹簧挡圈3。锁紧套4外圆周面上压有滚花,快换主体1安装好快换杆6后固定并穿过钻夹头7。 
如图l,先将装在钻床主轴中的快换主体2串装件中的锁紧套4向上推至弹簧挡圈3限位处,这时两个钢珠5就会从快换主体2上的两个钢珠孔里向外滚出一定距离,但不会从快换主体2中掉下。再将串装好刀具的快换杆6上端插入快换主体2的内孔中,转动快换杆的同时将锁紧套4向下轻压,使两个钢珠5压人两个钢珠孔里,同时也与快换杆6上的锁紧槽紧密配合。这时,锁紧套4靠自重就会使两个钢珠5同定住快换杆6。当更换快换杆时,一手扶住快换杆,一手将锁紧套4向上推至弹簧挡圈3限位处,这时钢珠就会松开快换杆,快换杆靠自重就会从快换主体2的内孔中自动掉下,然后再将另一个快换杆组件装入快换主体中。
