The utility model provides tapping guide parts, guiding components and spinning mechanism. A guide hole is arranged on the guide part, the guide hole is through hole, and the upper ring of the guide hole is provided with at least three clamps, which can be connected with the screw inserted in the guide hole; the interface between the guide hole and the guide part is plane, and the plane is provided with at least three rolling parts along the guide hole ring, and the rolling part is raised from the plane. The guide assembly includes fixtures, elastic parts and guide parts. The elastic parts are arranged between the fixtures and the guide parts. The elastic parts expand axially in the guide hole, and the screw can extend from the guide parts. The screw-in mechanism includes a rotating power component and a guiding component. The rolling parts on the end face of the guide part, the sliding friction and rolling friction between the variable guide part and the screw-in surface, make the screw-in smoother, and at the same time can form a certain protection on the screw-in surface. It is a kind of screw-in guide parts, guiding components and screw-in mechanism that can help screw tapping, improve the accuracy of tapping and enhance the tapping efficiency.

攻丝导向件、导向组件及旋入机构
本技术涉及机械安装领域,具体而言,涉及攻丝导向件、导向组件及旋入机构。
技术介绍
自攻螺钉也称为快牙螺丝,为钢制经表面镀锌钝化的快装紧固件,能够在转动拧入时,对质软或型薄的安装部件上攻出螺纹,并同时牢靠的固定于其上,具有使用方便,高效的特性。目前,在使用自攻螺钉时,刚开始攻丝时,由于自攻螺钉的位置不固定,容易发生晃动引起攻丝偏移,造成自攻螺钉无法拧入、拧入费力或自攻螺纹滑丝、螺纹精度差、连接不可靠的问题。
技术实现思路
有鉴于此,本技术的目的是为了克服现有技术中的不足,提供一种对攻丝螺钉进行导向,保证攻丝的精度的攻丝导向件、导向组件及旋入机构。为此,本技术提供如下技术方案:攻丝导向件,所述导向件上设有导向孔,所述导向孔为通孔,所述导向孔上环设有至少三个夹爪,每一所述夹爪可与插设于所述导向孔中的螺钉抵接;所述导向孔与所述导向件的交界面为平面,该平面上沿所述导向孔环设有至少三个滚动件,每一所述滚动件自该平面凸起。作为对上述的攻丝导向件的进一步可选的方案,所述导向件呈圆柱状,所述导向孔在圆柱上同轴设置,所述滚动件在所述导向件的端面圆周均匀分布。圆 ...
