Abstract

本实用新型公开了一种发动机用气门间隙调整螺钉，其特征在于，在螺柱的顶端设有调整卡口，凹槽设在螺柱的中间部位，在螺柱的底端设有球头，在球头与与凹槽之间设有相贯通的进气孔，外螺纹设在螺柱的外壁上。通过以上设置，本实用新型采用可控气氛保护多用炉对其表面渗碳和球头高频淬火，更好的保证了耐磨性。产品无论是从几何形状还是耐磨性，都达到使用要求。

Description

发动机用气门间隙调整螺钉
技术领域
    本实用新型涉及一种发动机零部件，具体说是一种发动机用气门间隙调整螺钉。 
背景技术
发动机用气门间隙调整螺钉，是用来连接气门挺杆和气门的，它的性能直接影响整个发动机的质量。发动机用气门间隙调整螺钉以前采用国外进口，但国外进口有很多不便：一是供货不及时，二是质量问题难协调，三是价格昂贵。 
发明内容
本实用新型的目的便是提供一种发动机用气门间隙调整螺钉。 
为了实现上述目的，本实用新型在螺柱的顶端设有调整卡口，凹槽设在螺柱的中间部位，在螺柱的底端设有球头，在球头与与凹槽之间设有相贯通的进气孔，外螺纹设在螺柱的外壁上。 
通过以上设置，本实用新型采用冷挤压成型，更好的保证了内部组织。采用可控气氛保护多用炉对其表面渗碳和球头高频淬火，更好的保证了耐磨性。产品无论是从几何形状还是耐磨性，都达到使用要求。 
附图说明
现结合附图对本实用新型做进一步说明。 
图1为本实用新型的结构示意图。 
图中：1、螺柱，2、调整卡口，3、凹槽，4、球头，5、进气孔，6、外螺纹。 
具体实施方式
 如图1所示，本实用新型在螺柱1的顶端设有调整卡口2，凹槽3设在螺柱1的中间部位，在螺柱1的底端设有球头4，在球头4与与凹槽3之间设有相贯通的进气孔5，外螺纹6设在螺柱1的外壁上。通过以上设置，本实用新型的球头4采用高频淬火，保证了本实用新型在运动的同时能够自身耐磨，且对气门挺杆磨削均匀。
