Abstract

本发明公开了一种错齿PCD球头铣刀，刀柄为圆柱结构，沿圆柱轴线有一切削液通孔，刀体亦为圆柱体结构，刀柄与刀体间有一过度斜坡，刃部为球面结构，有6刃结构，刀片之间60度夹角分布在圆周，错齿排列，刀片为PCD刀片且带有3-5度的刃倾角，每段切刃前均有一个切削液出口。本发明将原有的2刃铣刀改为6刃结构，PCD刀片带有3-5度的刃倾角，这样使切刃变短，分散切削受力，可有效降低加工时产生的振动。本发明每段切刃前都有一个切削液出口，使得切屑顺畅排出，可进行高效、稳定地加工。

Description

一种错齿PCD球头铣刀
技术领域
本发明涉及一种机械加工刀具，尤其涉及一种错齿PCD球头铣刀。
背景技术
目前国内较大直径PCD球头铣刀，如图1所示，是由两个PCD片焊接制作而成，在切削工件时，PCD切刃与工件同时接触部位长，瞬间切削阻力大，时有避刀情况发生，从而导致加工中刀具与工件振颤严重，使工件表面形成震纹，表面粗糙精度差，尺寸精度超差。
发明内容
本发明克服了现有技术中的不足，提供一种错齿PCD球头铣刀。
为了解决上述存在的技术问题，本发明是通过以下技术方案实现的：
一种错齿PCD球头铣刀，刀柄为圆柱结构，沿圆柱轴线有一切削液通孔，刀体亦为圆柱体结构，刀柄与刀体间有一过度斜坡，刃部为球面结构，有6刃结构，刀片之间60度夹角分布在圆周，错齿排列，刀片为PCD刀片且带有3-5度的刃倾角，每段切刃前均有一个切削液出口。
 
由于采用上述技术方案，本发明提供的一种错齿PCD球头铣刀具有这样的有益效果，将原有的2刃铣刀改为6刃结构，PCD刀片带有3-5度的刃倾角，这样使切刃变短，分散切削受力，可有效降低加工时产生的振动。每段切刃前都有一个切削液出口，使得切屑顺畅排出，可进行高效、稳定地加工。
附图说明
图1是现有技术2刀片结构的铣刀结构示意图；
图2是本发明的一种错齿PCD球头铣刀结构示意图；
图3本发明侧视图
图4、图5、图6、是本发明PCD切刃分布位置，其中1、2、3、4、5、6是PCD。
具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述：
一种错齿PCD球头铣刀，如图2-6所示，刀柄为圆柱结构，沿圆柱轴线有一切削液通孔，刀体亦为圆柱体结构，刀柄与刀体间有一过度斜坡，刃部为球面结构，有6刃结构，刀片之间60度夹角分布在圆周，错齿排列，如图3所示，刀片1与刀片3、5的夹角分别是60o、120o，刀片2与刀片4、6的夹角也分别是60o、120o，其中图4-6是PCD刀片的实际位置，刀片为PCD刀片且带有3-5度的刃倾角，每段切刃前均有一个切削液出口。
