新型锁键螺套在树脂基复合材料上的应用研究

Application of New Type Key-Locking Insert in the Resin Matrix Composites

锁键螺套作为一种新型的内螺纹紧固件,具有安装方便、连接可靠、便于拆卸等优点,解决了钢丝螺套使用中的一些问题。结合使用中的经验,介绍了锁键螺套的结构特点和安装原理,详细论述了锁键螺套在树脂基复合材料上的安装方法、工艺参数和应用效果。应用结果表明,采用气动冲压工艺可以实现锁键螺套在树脂基复合材料上的安全装配,安装效率高且拆卸方便。

Key-locked insert is a new-style fastener for screw threads, which has many advantages such as convenient installation, reliably connection, easy disassembly, can solve some problems in use of wire thread insert. Combining with the working experience, the structural characteristic of the key-locked insert and its installing principle are introduced. The method of installation, technological parameter and application effect on the resin matrix composites are also discussed. The results of application indicated that to use technology of pneumatic punching press can safety assembly, high installa- tion efficiency and easy disassembly in the resin metrix composites.
