Abstract

本实用新型涉及一种短槽孔刀具,包括刀柄、刀杆和刀尖,所述的刀尖为中间低四周高的鱼尾形状,在刀杆和刀尖上有连贯的螺旋刀刃。本实用新型的短槽孔刀具加工短槽孔时,刀尖受力比较均匀,不易发生变形,加工尺寸稳定。

Description

短槽孔刀具
技术领域
本实用新型涉及一种短槽孔(长度与宽度的比为1~2的槽孔)的加工刀具。
背景技术
现有技术中,对孔的加工基本上是由钻头来完成的。如附图3所示,用钻头加工短槽孔时,钻头需要横向移动,由于钻头的一侧已加工完,钻头在加工过程中不可避免地左右受力不均,刀尖变形较大,从而造成加工尺寸不稳定。在PCB板等对加工精度要求比较高的材料上加工短槽孔时,传统刀具常常无法满足人们的需要。
实用新型内容
本实用新型的目的在于提供一种加工短槽孔时刀尖不易变形,加工尺寸稳定的短槽孔刀具。
为了达到以上目的,本实用新型采用的方案是:一种短槽孔刀具,包括刀柄、刀杆和刀尖,所述的刀尖为中间低四周高的鱼尾形状,在刀杆和刀尖上有连贯的螺旋刀刃。
本实用新型的短槽孔刀具加工短槽孔时,刀尖受力比较均匀,不易发生变形,加工尺寸稳定,本实用新型尤其适合PCB板等对加工精度要求比较高的材料。
附图说明
附图1为本实用新型的短槽孔刀具的结构示意图;
附图2为用本实用新型的短槽孔刀具对短槽孔的加工示意图;
附图3为用钻头对短槽孔的加工示意图。
其中:1、刀柄;2、刀杆;3、刀尖;4、刀刃。
具体实施方式
下面结合附图对本实用新型作进一步的说明。
如图1所示,一种短槽孔刀具,包括刀柄1、刀杆2和刀尖3,所述的刀尖3为中间低四周高的鱼尾形状,在刀杆2和刀尖3上有连贯的螺旋刀刃4。
如图2所示,用本实用新型的短槽孔刀具对短槽孔加工时,刀尖受力比较均匀,不易发生变形,加工出来的短槽孔尺寸稳定,能够满足用户的需求。
