Abstract

本实用新型涉及一种车削复合管坯的伞顶尖。它由夹持柄和圆台状顶头组成,顶头的圆锥面上有增加摩擦力的锯齿。它结构简单,可以实现复合管坯一次加工,省时省力。

Description

车削复合管坯的伞顶尖
技术领域
本实用新型涉及一种车削加工用的顶尖,特别适合车削复合管坯。
背景技术
现有复合管坯车削外圆时,管坯一端用顶尖顶住,另一端用卡盘卡爪夹住,这样复合管坯被卡爪夹住部分就车削不到,最后还要将管坯掉头找正,再车被夹住部分,很费时费力。
发明内容
为了克服现有技术的缺点,本实用新型提供一种车削复合管坯的伞顶尖,它结构简单,一次加工,省时省力。
本实用新型解决其技术问题所采取的技术方案是:它由夹持柄和圆台状顶头组成,顶头的圆锥面上有增加摩擦力的锯齿。
本实用新型结构简单,可以实现复合管坯一次加工,省时省力。
附图说明
下面结合附图和实施例对本本实用新型进一步说明。
图1为本实用新型剖视图。
具体实施方式
如图1所示,它由夹持柄1和圆台状顶头2组成,顶头2的圆锥面上有增加摩擦力的锯齿3。
所述的夹持柄1和顶头2通过螺纹固定,更换不同外径的顶头2,可以加工不同直径的复合管坯。
所述顶头2外沿直径D为大于管坯内孔直径50mm。
所述顶头2圆锥面的锥度为45°。
