Abstract

本实用新型公开了一种中心孔开孔刀具,包括刀头和刀柄,刀头与刀柄固定连接,所述的刀头的前刃部设有螺旋角,刀柄与刀头的前刃部连接处依次设有120°圆锥端和60°圆锥端,所述的刀柄的另一端设有另一个刀头。本实用新型的有益效果是:前端设有螺旋角,使刀具切削时受力点分散,减少刀具的磨损,同时提高刀具寿命,同时两端均设有刀头,节约了资源,同时刀具设有120°和60°的圆锥端,可以有效地降低刀具受力时的径向跳动,提高生产效率。

Description

一种中心孔开孔刀具
技术领域
本实用新型涉及加工刀具制造领域,尤其涉及一种中心孔开孔刀具。
背景技术
在凸轮轴的生产过程中,尾端孔形状各个厂家设计均为非标的中心孔,常规的中心孔开孔刀具在加工时,往往需要分多道工序加工,效率低下,不但浪费时间而且耗费人力,同时传统刀具在加工时径向跳动的风险也大。
实用新型内容
为了克服上述缺陷,本实用新型提供一种中心孔开孔刀具。
为了实现上述目的,本实用新型的技术方案是:一种中心孔开孔刀具,包括刀头和刀柄,刀头与刀柄固定连接,所述的刀头的前刃部设有螺旋角,刀柄与刀头的前刃部连接处依次设有120°圆锥端和60°圆锥端,所述的刀柄的另一端设有另一个刀头。
进一步,所述的刀柄设有对称的螺旋形的圆弧形屑。
本实用新型的有益效果是:前端设有螺旋角,使刀具切削时受力点分散,减少刀具的磨损,同时提高刀具寿命,同时两端均设有刀头,节约了资源,同时刀具设有120°和60°的圆锥端,可以有效地降低刀具受力时的径向跳动,提高生产效率。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
下面结合具体实施例对本实用新型做进一步的说明。
如图1所示,一种中心孔开孔刀具,一种中心孔开孔刀具,包括刀头1和刀柄2,刀头1与刀柄2固定连接,所述的刀头1的前刃部设有螺旋角3,刀柄2与刀头1的前刃部连接处依次设有120°圆锥端4和60°圆锥端5,所述的刀柄2的另一端设有另一个刀头1。
本实用新型的技术方案不限于上述具体实施例的限制,凡是根据本实用新型的技术方案做出的技术变形,均落入本实用新型的保护范围之内。
