Abstract

本实用新型属于飞机工装制造技术,特别是涉及一种用于盲孔中的透气定位销。一种用于插入零件的盲孔中的透气定位销,在定位销的中心有1个与定位销轴线平行的轴向透气孔和1个与定位销轴线垂直的横向透气孔,轴向透气孔和横向透气孔的中心线相交且相通。轴向透气孔和横向透气孔的直径尺寸小于定位销的直径尺寸。本实用新型便于向零件盲孔中插入定位销,避免了定位销斜定位和盲孔内气体排放不畅而造成定位销插入困难。

Description

透气定位销
技术领域
本实用新型属于飞机工装制造技术,特别是涉及一种用于盲孔中的透气定位销。
背景技术
现有的定位销在零件的盲孔中插入时,由于零件的盲孔中的残留气体没有排放,使定位销的完全插入造成困难,甚至造成定位销斜定位破坏零件的定位孔。
发明内容
本发明的目的是:
提供一种便于插入零件的盲孔的定位销。
本发明的技术方案是:
一种用于插入零件的盲孔中的透气定位销,在定位销的中心有1个与定位销轴线平行的轴向透气孔和1个与定位销轴线垂直的横向透气孔,轴向透气孔和横向透气孔的中心线相交且相通。轴向透气孔和横向透气孔的直径尺寸小于定位销的直径尺寸。
本发明的优点是:
本实用新型便于向零件盲孔中插入定位销,避免了定位销斜定位和盲孔内气体排放不畅而造成定位销插入困难。
附图说明
附图1为是本实用新型透气定位销的结构示意图。
具体实施方式
本实用新型的工作原理是:
使用时,将透气定位销1插入定位盲孔中,用定位盲孔引导透气定位销1的外园作为轴心,将透气定位销1插入定位盲孔中。定位盲孔中的残留气体由透气定位销1的轴向透气孔2和横向透气孔3排出。
由于定位盲孔中的残留气体被顺畅排出,所以透气定位销1插入定位盲孔中十分方便。

Claims (1)

1.一种透气定位销,其特征在于,在定位销的中心有1个与定位销轴线平行的轴向透气孔和1个与定位销轴线垂直的横向透气孔,轴向透气孔和横向透气孔的中心线相交且相通,轴向透气孔和横向透气孔的直径尺寸小于定位销的直径尺寸。
