Abstract

本实用新型公开了一种钻孔工具,包括钻杆和钻卡头,传动轴上设有皮带轮,所述传动轴的上端设有与摇臂钻钻杆内孔相配的锥体,所述传动轴的下端转动支撑于钻臂一端的孔中,钻杆的中部转配于所述钻臂另一端的孔中,所述钻杆的上端设有另一个皮带轮,此另一皮带轮与所述传动轴上的皮带轮相对,所述钻杆的下端为钻卡头。本实用新型具有能在狭小空间进行钻孔的显著优点。

Description

一种钻孔工具
技术领域:
本实用新型涉及一种切削技术,特别是用于在狭小空间钻孔的工具。
背景技术:
在某些零件中需要钻孔的空间狭小,常规的小型钻床或者手电钻无法进到该空间实施钻孔,成为钻具的课题。
发明内容:
本实用新型目的是提供一种在狭小空间进行钻孔的钻孔工具。
实现本实用新型目的的技术方案是,一种钻孔工具,包括钻杆和钻卡头,其特征在于:传动轴上设有皮带轮,所述传动轴的上端设有与摇臂钻钻杆内孔相配的锥体,所述传动轴的下端转动支撑于钻臂一端的孔中,钻杆的中部转配于所述钻臂另一端的孔中,所述钻杆的上端设有另一个皮带轮,此另一皮带轮与所述传动轴上的皮带轮相对,所述钻杆的下端为钻卡头。
本实用新型与现有技术比较具有能在狭小空间进行钻孔的显著优点。
附图说明:
图1是本实用新型钻孔工具的结构示意图。
具体实施方式:
现有的台钻和手电钻均自身有动力装置(电机)、传动机构和钻卡头,使其轴向长度较长超过了钻孔空间的高度。为了能够在小空间实施钻孔,钻卡头是不可缺少的,采取措施借用动力并尽量减小传动机构的尺寸,本实用新型采用下述技术方案,动力采用摇臂钻动力,传动轴1的上端设有与摇臂钻钻杆4孔相配的锥形柄3,所述传动轴上设有皮带轮5,所述传动轴的下端与钻臂2一端中的轴承6内圈连接,所述钻臂的另一端设有另一轴承,钻杆8与所述另一轴承的内圈连接,所述钻杆的上端设有另一个皮带轮7与所述传动轴上的皮带轮相对,所述钻杆的下端设有钻卡头9。由于采用了上述技术方案,钻具的轴向尺寸较小解决了狭小空间零件10的钻孔和攻丝的问题。
