一种新型螺纹刀具
本专利技术涉及一种机械五金件,尤其涉及一种机床加工用刀具,更具体地说,涉及一种新型螺纹刀具。
技术介绍
现有的切削用螺纹刀具的类型有多种,广泛应用于切削加工领域。常用的螺纹刀具包括刀座和螺纹刀片,所述螺纹刀片通过锁紧装置固定于刀座上。这种结构的螺纹刀具的螺纹刀片较少,工作效率较低。另外,螺纹刀具在使用过程中会产生较多热量,因此,在一定程度上加快了螺纹刀片的损坏效率,使得螺纹刀具的使用寿命较低。
技术实现思路
有鉴于此,本专利技术提供了一种新型螺纹刀具,解决现有技术中存在的问题,具体方案如下:一种新型螺纹刀具,包括圆盘底座,所述圆盘底座外周部均匀设有多个刀座,所述刀座内安装有螺纹刀片,所述螺纹刀片和刀座上均设有安装孔,所述安装孔内设有螺栓,所述螺纹刀片底面设有凸块,所述刀座顶面设有与凸块相匹配的凹槽,所述凸块嵌装在凹槽内;所述螺纹刀片顶面设有低于螺纹刀片顶面的凹陷部,所述圆盘底座中部设有与转轴相配合的转轴孔,所述转轴为中空结构,转轴内设有导水管,所述导水管伸出转轴孔且导水管出口由防水橡胶塞密封,伸出转轴孔的导水管外周面连接有多个分支管,多个分支管分别沿着转轴孔至刀座方向设置,分支管管口设有喷嘴。本专利技术提供的新型螺纹刀具,结构简单,一个圆盘底座上设有多个刀座,提高了工作效率,螺纹刀片底面凸块与刀座顶面凹槽配合连接,能够有效固定螺纹刀片,避免螺纹刀片出现热变形;转轴内设有导水管,导水管连接有多个分支管,分支管的水通过喷嘴喷入螺纹刀片处,能够有效冷却螺纹刀片,螺纹刀片上设有凹陷部,螺纹刀片的安装孔设于凹陷部内,分支管内的水流入凹陷部,由凹陷部流至 ...
