The invention discloses a parallel spacecraft ejection separation device. The ejection separation device comprises a mounting bottom plate and an upper mounting plate which are oppositely arranged, the two supporting beams are arranged in parallel and are fixedly mounted on the mounting bottom plate; a multi-connecting-rod mechanism is hinged between each supporting beam and the upper mounting plate; the two multi-connecting-rod mechanisms are symmetrically arranged, and a plurality of parallel connecting shafts are connected between the two multi-connecting-rod mechanisms; the sliding part is mounted between the two supporting beams in a sliding manner along the supporting beams, and is hinged with one connecting rod in the multi-connecting-rod mechanism; the parallel cylinder is fixedly mounted on the mounting bottom plate; piston rods of the parallel cylinders are fixedly connected with the sliding component; each supporting beam is fixedly provided with a damper. According to the ejection separation device, the ejection stroke, the ejection load and the ejection separation angle can be adjusted, pneumatic separation is assisted, the ejection safety is improved, the universality of an ejection mechanism is improved, and different second-stage spacecrafts can be ejected and separated.

    本发明公开了一种并联航天器弹射分离装置,该弹射分离装置包括相对设置的安装底板和上安装板;两个支撑梁平行设置且固定安装于安装底板;在每个支撑梁与上安装板之间均铰接有一个多连杆机构;两个多连杆机构对称设置,并且之间连接有多个平行的连轴;滑动部件沿支撑梁滑动地安装于两个支撑梁之间,并与多连杆机构中的一个连杆铰接;并联气缸固定安装于安装底板;并联气缸的活塞杆与滑动部件固定连接;每个支撑梁上均固定安装有一个阻尼器。上述弹射分离装置能够实现弹射行程、弹射载荷、弹射分离角度的可调节,辅助气动分离增加发射安全性,并增加了弹射机构的普适性,可弹射分离不同的第二级航天器。
