基于SMA驱动的扭转弹簧分离装置优化设计
摘要
在扭转弹簧分离装置中,拔销器是一个十分关键的零部件,直接影响到分离装置的使用效果。拔销器由一个偏置弹簧和一个SMA记忆合金驱动弹簧组成,偏执弹簧的作用是将SMA记忆合金驱动弹簧复位,它们在一起能够实现销子的拔出与插入。文章分析了形状记忆效应影响因素,介绍了SMA拔销器的原理,并通过润滑和公差配合等方面对扭转弹簧分离装置进行了优化设计。
In the torsional spring separation device, the pin puller is a very key component, which directly affects the use of the separation device. The pin puller consists of a bias spring and a SMA memory alloy drive spring. The bigoted spring is used to reset the SMA memory alloy drive spring. Together, the pins can be pulled out and inserted. This paper analyzes the influencing factors of shape memory effect, introduces the principle of SMA pin puller, and optimizes the design of torsion spring separator through lubrication and tolerance fit.
