Description

一种攻牙装置及其多工位钻孔、攻牙一体化设备 技术领域
本发明涉及一种攻牙装置及其多工位钻孔、攻牙一体化设备,特别涉及精密的螺纹孔成形攻牙装置,及多工位其钻孔、攻牙一体化设备。
背景技术
现有的攻牙方式多是采用手动的使用丝锥扳手套在丝锥上进行单个螺纹孔的攻牙。为提高工作效率,同时对多个螺纹孔进行攻牙的方法则采用类似于多孔钻的方式,利用多个钻夹头夹持多个丝锥同时对多个孔位进行攻牙。由于每一丝锥都对应有一钻夹头,因此,所能加工的两个相邻孔的孔间距是不能低于两个钻夹头的半径之和;对于一些微小孔间距,亦或两个相邻孔的孔间距小于两个钻夹头的半径之和时,无法采用现有的类似排钻或多孔钻进行同时钻孔的加工方式。发明人发明了一种丝锥,如专利申请号201710415245.4,该种丝锥设有多边形棱柱体的丝锥滑动传动杆部;采用攻牙同步带轮带动丝锥滑动传动杆部的传动方式,利用攻牙同步带轮带动丝锥转动,丝锥的丝锥滑动传动杆部同时相对攻牙同步带轮向下移动实现对螺纹孔进行攻牙的方式,从而不需要使用钻夹头,实现可以在任意孔间距的多个孔位的同时加工,特别是适用微小孔间距的多个孔位同时进行攻牙,具有大幅提高生产效率的优点。但由于该种丝锥为专用的的丝锥,其制造的成本高,同时结构上与现有的不带有丝锥滑动传动杆部的丝锥差异巨大,专用丝锥与普通丝锥两者之间难以进行结合或互换。
发明内容
本发明的目的在于提供一种攻牙装置,该装置利用分体拆接式丝锥和丝锥主轴传动件配合结构形式,通过丝锥卡制件把丝锥和丝锥主轴传动件卡扣在一起,丝锥随同丝锥主轴传动件运动,该丝锥主轴传动件与设有丝锥卡制部的丝锥配合,构成一个分体拆接式的丝锥主轴,可以直接与丝锥传动轮配合,在丝锥传动轮的带动下既是作为一个带动丝锥转动的攻牙主轴进行旋转,又是作为一个丝锥进行攻牙加工,实现精准的攻牙定位加工,保证不会偏孔偏牙,同时直接进行攻牙部份的丝锥部件又与现有的丝锥结构相接近,可以利用现有普通丝锥进行简单加工后制造而成,降低了装置的制造成本,且易于和现有的丝锥结合。
本发明的再一目的在于提供一种多工位攻牙装置,有效地利用本发明的丝锥、丝锥主轴传动件所构成的多个攻牙装置,采用同步带形式,同时实现多工位攻牙,一方面, 取消由钻夹头夹持丝锥固定方式,实现不受钻夹头半径的影响,达到微小孔间距的同步攻牙功能。另的一方面,所使用的丝锥成本低,采用简单加工即可与普通丝锥进行互换,具有很好的通用性能,降低了产品加工成本。同时,丝锥与主轴传动套之间的定位关系可以保证螺纹加工精度高,位置准确。
本发明的另一目的在于提供本发明攻牙装置的装配方法,完成攻牙装置的构件装配。
本发明的另一目的在于提供一种攻牙装置的工作方法,实现多工位攻牙工作简便,动作可靠,加工精度高。
本发明的又一目的于提供多孔位钻孔、攻牙一体化设备,在一台设备上对同时对工件钻孔和攻牙工作,实现精准的钻孔和攻牙定位加工,同时钻孔和攻牙的位置精准,孔位正确,钻孔和攻牙工作质量好,不会偏孔或偏牙,大幅降低设备使用、加工制造成本。
