Abstract

一种深孔钻,包括固定一体联接的柄部和钻杆。钻杆端面上设有刀刃。在所述的钻杆上匀设有多条抛物线形的排屑槽。在所述的钻杆内开设有多个内冷孔。本实用新型通过改进排屑槽的形状,采用抛物线形使切屑很容易从排屑槽里排出,加工时可以一次性加工到底,不用退刀,同时还不易断刀,提高了加工效率。

Description

一种深孔钻
技术领域
本实用新型涉及钻头领域,特别涉及一种深孔钻。
背景技术
深孔钻是专门用于加工深孔的钻头。在机械加工中通常把孔深与孔径之比大于6的孔称为深孔。深孔钻削时,由于切屑不易排出,必须加工一段距离后退一下刀,排出点切屑才可以,否则容易断刀。
实用新型内容
本实用新型的目的是提供一种深孔钻,本深孔钻通过改进排屑槽的形状,使切屑很容易排出,解决了不易排屑的问题,提高了加工效率。
采用的技术方案是:
一种深孔钻,包括固定一体联接的柄部和钻杆。钻杆端面上设有刀刃。
其技术要点在于:
在所述的钻杆上匀设有多条抛物线形的排屑槽。
在所述的钻杆内开设有多个内冷孔。
其优点在于:
本实用新型通过改进排屑槽的形状,采用抛物线形使切屑很容易从排屑槽里排出,加工时可以一次性加工到底,不用退刀,同时还不易断刀,提高了加工效率。
附图说明
图1为本实用新型的主视图。
图2为本实用新型的侧视图。
具体实施方式
一种深孔钻,包括固定一体联接的柄部1和钻杆2。钻杆2端面上设有刀刃3。
在所述的钻杆2上匀设有两条抛物线形的排屑槽4。
在所述的钻杆2内开设有两个内冷孔5。
