Abstract

本发明涉及一种改进的圆柱销钉,属机械标准件领域。包括圆柱销钉,在圆柱销钉的侧面开有一条平缝,在圆柱销钉的两个底面加工有螺丝孔。由于采用了上述技术方案,通过在传统圆柱销钉圆柱面开有的平缝,能使装配时盲孔中的气体顺利过平缝排出,而且由于平缝足够小基本不影响圆柱销钉的强度。圆柱销钉拆卸时,通过拔头拧入底面的螺丝孔将圆柱销钉从盲孔中顺利拆除。本发明的有益效果是,结构简单,制作容易,使用方便。

Description

一种改进的圆柱销钉
技术领域
本发明涉及一种改进的圆柱销钉,属机械标准件领域。 
背景技术
由于传统圆柱销钉和孔采用过渡配合,在一些表面精度和尺寸精度高的零件配合中,传统圆柱销钉与孔配合较紧,造成装配圆柱销钉时盲孔中的原有空气无法排除,圆柱销钉难以装配进去。 
发明内容
为解决传统圆柱销钉存在的上述问题,本发明提供一种改进的圆柱销钉。 
本发明是通过如下技术方案实现的:一种改进的圆柱销钉,包括圆柱销钉,在圆柱销钉的侧面开有一条平缝,在圆柱销钉的两个底面加工有螺丝孔。 
由于采用了上述技术方案,通过在传统圆柱销钉圆柱面开有的平缝,能使装配时盲孔中的气体顺利过平缝排出,而且由于平缝足够小基本不影响圆柱销钉的强度。圆柱销钉拆卸时,通过拔头拧入底面的螺丝孔将圆柱销钉从盲孔中顺利拆除。 
本发明的有益效果是,结构简单,制作容易,使用方便。 
附图说明
图1是本发明结构示意图; 
图2是图1的左视图;
图3是图2平缝的放大图。
    图中:1、螺纹孔,2、圆柱销钉,3、平缝。 
具体实施方式
    下面结合附图和实施例对本发明进一步说明。 
如图1、图2和图3所示,一种改进的圆柱销钉,包括圆柱销钉2,在圆柱销钉2的侧面开有一条平缝3,在圆柱销钉2的两个底面加工有螺丝孔1。平缝3应开的足够小以不影响圆柱销钉的强度为准,本实施例平缝3的深度为0.2~0.5mm。 

Claims (2)

1.一种改进的圆柱销钉,包括圆柱销钉(2),其特征是,在圆柱销钉(2)的侧面开有一条平缝(3),在圆柱销钉(2)的两个底面加工有螺丝孔(1)。
2.根据权利要求1所述的一种改进的圆柱销钉,其特征是,平缝(3)的深度为0.2~0.5mm。
