Description

堵头
技术领域:
本实用新型涉及一种快速的堵孔零件,具体应用于机械零部件中孔的堵塞。
背景技术
现有的堵头都是用锥形堵、球堵和螺纹堵塞等,其对孔的粗糙度、圆柱度和尺寸公差要求高,且安装复杂。
实用新型内容
为了克服上述缺陷,本实用新型的目的是提供一种堵头。
为了实现上述目的,本实用新型采用如下技术方案:
堵头,其包括淬硬的碳钢钉芯、铝套,碳钢钉芯的头部设置密封凸筋,组装后与铝套配合形成密封环,碳钢钉芯的头部与螺纹之间设置拉断处。
特性及优点
1)防漏性能好;
2)对孔的粗糙度、圆柱度和尺寸公差要求低,不必进行铰孔等精加工;
3)安装简便,快捷,具有较高的装配效率。
附图说明:
图1为本实用新型的结构示意图。
图2~图4为堵头的使用过程。
具体实施方式
下面结合附图进一步说明:
如图1所示,堵头,其包括淬硬的碳钢钉芯1、铝套2,碳钢钉芯1的头部设置密封凸筋,组装后与铝套2配合形成密封环3,碳钢钉芯的头部与螺纹之间设置拉断处4。
如图2~4所示,先将堵头放于铆钉枪6并置于需要堵的孔7中,铆钉枪工作使堵头的头部挤压铝套2,铝套2膨胀,填满孔7,达到预定载荷,堵头在拉断处4断裂,完成装配。
最后,应当指出,以上实施例仅是本实用新型较有代表性的例子。显然,本实用新型的技术方案并不限于上述实施例,还可以有许多变形。本领域的普通技术人员能从本实用新型公开的内容直接导出或联想到的所有变形,均应认为是本实用新型的保护范围。
