Abstract

一种机械加工的无刃铰刀,包括刀柄、刀头,其特征是刀头外圆面上开有轴向刀片槽,刀片槽内安装有刀片,刀片外侧面为与刀头外圆面一致的弧形面、露出刀头外圆面1—2㎜,刀片槽两侧的刀头外圆面上有对称的内凹圆弧过渡面,内凹圆弧过渡面与刀头外圆面的前、后夹角为-30°~-60°。作业时,以挤压的方式实现对工件内孔切削加工,加工余量小,从而有效降低被加工内孔的表面粗糙度值,提高内孔的几何加工精度,结构简单,成本低,操作方便,特别适合较高精度内孔的加工。

Description

一种无刃铰刀
技术领域
本实用新型涉及一种机械加工刀具,特别是一种无刃铰刀。
背景技术
目前,机械加工工艺中,对工件内孔的精加工普遍使用的刀具为有刃铰刀,使用过程中刀刃磨损快,刀刃磨损后难以保证内孔表面的粗糙度,成本高,使用不方便。
发明内容
本实用新型的目的是为了克服上述不足之处,而提供一种结构简单,成本低,操作方便,适合较高精度内孔加工的无刃铰刀。
本实用新型的目的是这样实现的:一种无刃铰刀,包括刀柄、刀头,其特征是刀头外圆面上开有轴向刀片槽,刀片槽内安装有刀片,刀片外侧面为与刀头外圆面一致的弧形面、露出刀头外圆面1—2㎜,刀片槽两侧的刀头外圆面上有对称的内凹圆弧过渡面,内凹圆弧过渡面与刀头外圆面的前、后夹角为-30°~-60°。
本实用新型由于采用以上设计,作业时,以挤压的方式实现对工件内孔切削加工,产生的废料从内凹圆弧过渡面的间隙排出,加工余量小,从而有效降低被加工内孔的表面粗糙度值,提高内孔的几何加工精度,结构简单,成本低,操作方便,特别适合较高精度内孔的加工。
附图说明
图1为本实用新型实施例结构示意图;
图2为图1的右视图。
具体实施方式
现结合附图所示实施例对本实用新型作出详细说明。
如图1、图2所示,一种无刃铰刀,包括刀柄1、刀头2,刀头2外圆面上均匀地开有四条轴向刀片槽3,刀片槽3内安装有刀片4,刀片4外侧面为与刀头2外圆面一致的弧形面、露出刀头2外圆面1—2㎜,刀片槽3两侧的刀头2外圆面上有对称的内凹圆弧过渡面5,内凹圆弧过渡面5与刀头2外圆面的前、后夹角6、7为-30°~-60°。
