The invention provides a multi-level lever-based multi-layer combined satellite pressing and releasing mechanism and method. The lower parts of two pressing rods in the pressing and releasing mechanism are respectively connected with an unlocking assembly at the bottom through one-way rotating hinges; the unlocking assembly is matched and attached to a force bearing column of a satellite at the bottom, and after the satellites are stacked layer by layer, the pressing disc is matched and attached to a satellite force bearing column at the top. The top ends of the two pressing rods penetrate through two connecting holes preset in the pressing disc and are connected and pre-tightened through external threads at the top ends of the pressing rods and pre-tightening nuts, downward pressing force is provided for the satellite force bearing column, when the unlocking assembly is unlocked, the pressing force of the pressing rods is released, the pressing rods drive the pressing disc to bounce upwards, and then the satellite force bearing column is unlocked. The pressing disc is separated from the satellite force bearing column at the top, a separation spring is installed between the pressing releasing mechanism and the satellite force bearing column, the separation spring is tightly attached to the outer surface of the satellite force bearing column and is compressed, unfolding driving force of the pressing rod after separation is provided, and after the pressing disc is separated from the satellite force bearing column at the top, the pressing disc swings outwards under the action of the separation spring. And the constraint on the satellites is relieved, and the multi-layer stacked satellites can be reliably pressed and separated.
本发明提供了一种基于多级杠杆的多层组合卫星压紧释放机构及方法,该压紧释放机构中两个压紧杆下部分别通过单向转动铰链与底部的解锁组件连接;解锁组件与底部卫星的承力柱配合贴紧,卫星层层堆叠后压紧盘与顶部的卫星承力柱配合贴紧;两个压紧杆顶端穿过压紧盘预置的两个连接孔,并通过压紧杆顶端的外螺纹与预紧螺母进行连接预紧,给卫星承力柱提供向下的压紧力,在解锁组件解锁时压紧杆的压紧力释放,压紧杆带动压紧盘向上弹起,压紧盘与顶部的卫星承力柱脱离,压紧释放机构与卫星承力柱之间安装分离弹簧,分离弹簧与卫星承力柱外表面贴紧并压缩,提供分离后压紧杆的展开驱动力,压紧盘与顶部的卫星承力柱脱离后,在分离弹簧的作用下向外摆开,解除对卫星的约束,能够将多层堆叠式卫星可靠压紧与分离。
