Abstract

本实用新型涉及一种自攻螺栓,包含螺杆和螺帽,所述的螺杆一端连接螺帽,另一端尾端设有切削口。与现有技术相比,本实用新型具有节省工序及加工时间、降低生产成本等优点。

Description

一种自攻螺栓
技术领域
本实用新型涉及一种螺栓,尤其是涉及一种自攻螺栓。
背景技术
螺栓是一种用途十分广泛的连接配件,螺栓的加工工艺随着生产的需求得到不断的改进。目前在螺栓安装过程中,一般螺栓孔须经过丝锥攻丝后才能将螺栓拧入,也就是在光孔的基础上利用丝锥攻出孔内螺纹,然后将螺栓拧入。此工序相当繁复。
发明内容
本实用新型的目的就是针对现有技术存在的不足,提供一种可节省时间、降低生产成本的自攻螺栓。
本实用新型的目的可以通过以下技术方案来实现:一种自攻螺栓,包含螺杆和螺帽,所述的螺杆一端连接螺帽,另一端尾端设有切削口。
所述的切削口为方形或三角形。
所述的切削口设有至少一个。
与现有技术相比,一般螺栓孔必须经过丝锥攻丝后才能将螺栓拧入,本实用新型通过优化螺纹尾端达到直接通过螺栓的螺纹在旋进的过程中将螺栓孔的内螺纹挤压成型,也就是装配件在装配过程中自行形成内螺纹,节省了用丝锥攻丝这道工序。
附图说明
图1为本实用新型自攻螺栓的一种结构示意图;
图2为本实用新型自攻螺栓的另一种结构示意图;
图3为本实用新型自攻螺栓的侧视图。
具体实施方式
下面结合附图对本实用新型的实施例作详细说明。
实施例1
如图1和3所示,一种自攻螺栓,包含螺杆2和螺帽1,所述的螺杆2一端连接螺帽1,另一端尾端设有切削口3。所述的切削口3设有一个,形状为方形。装配件在装配过程中,通过切削口和螺杆上的螺纹在旋进的过程中将螺栓孔的内螺纹挤压成型,也就是“自攻”,节省了用丝锥攻丝这道工序。
实施例2
如图2和3所示,一种自攻螺栓,该螺栓的切削口3设有一个,形状为三角形。其它同实施例1。

Claims (3)

1.一种自攻螺栓,包含螺杆和螺帽,其特征在于,所述的螺杆一端连接螺帽,另一端尾端设有切削口。
2.根据权利要求1所述的一种自攻螺栓,其特征在于,所述的切削口为方形或三角形。
3.根据权利要求1所述的一种自攻螺栓,其特征在于,所述的切削口设有至少一个。
