A core rivet joint component with high pre tightening force and high vibration protection, including nail sleeve, spring and core. The nail sleeve is composed of the head of the nail sleeve, the outer circle of the nail sleeve, the inner thread, the step hole, the light hole and the end face, and the core is formed by the head of the core, the outer thread, the broken neck slot, the ring groove and the light rod, and the spring is set on the nail sleeve and in the nail sleeve. The core rod passes through the nail sleeve and the spring, the core rod passes the nail sleeve and the spring, the outer thread of the core and the inner thread of the nail sleeve are connected with the thread, the end face of the nail sleeve is fitted to the head of the core, and the gap is used between the core and the spring. The invention adopts the thread connection and the spring support technology to greatly improve the reliability and prevention of the connection of the nail rod. It can not only solve the problem of low assembly efficiency, reduce the assembly cost, but also have high pre tightening force and anti vibration function, and can reduce the weight, safety and reliability, and maintain convenient and quick.

一种具有高预紧力高防震动的抽芯铆钉连接组件
本专利技术涉及一种抽芯铆钉连接组件,特别是涉及一种具有高预紧力高防震动的抽芯铆钉连接组件。
技术介绍
在飞机、火箭、导弹、高铁等部件装配连接中过去的连接主要采用螺栓加垫圈、螺母的连接结构,该结构装配过程中速度慢效率低下,另外受到高速运转螺母连接可靠容易松动,使连接失效。针对连接失效的问题现在已有带自锁功能的自锁螺母大量运用,该问题得到了较好的解决,但仍然存在装配速度慢,效率低下的问题。于是抽芯铆钉的运用解决了装配问题,但在抽芯铆钉的运用中,防震动及安装预紧力矩低等问题得不到解决。
技术实现思路
本专利技术是为了解决现有技术中存在的装配效率低下、安装预紧力低、容易松动的技术问题。一种具有高预紧力高防震动的抽芯铆钉连接组件,主要包括钉套1、弹簧2和芯杆3;所述钉套1由钉套头部1.1、钉套外圆1.2、内螺纹1.3、台阶孔1.4、光孔1.5及端面1.6组成;所述芯杆3由芯杆头部3.1、外螺纹3.2、断颈槽3.3、拉环槽3.4及光杆3.5组成;所述弹簧2设置于钉套1上,在钉套1的变形孔1.3处呈间隙配合;所述芯杆3穿过钉套1和弹簧2, ...
