The invention relates to a high-reliability holding claw type on-orbit filling mechanism and method. The filling mechanism comprises a driving end and a driven end. Before capturing, the M holding claws at the driving end are in an open state; when the driven end is within the capturing range of the driving end, the driving mechanism drives the moving plate to move downwards, the moving plate drags the holding claws to move downwards in a linear mode through the holding claw shaft system, the holding claws are gradually folded and move downwards under the interaction of the cam pair to capture the driven end, then the holding claws continue to be folded to be in the vertical state, then the holding claws start to move vertically, and the driven end is captured. The driven end is pressed on the top plate; and then the holding claw continues to vertically move downwards to enable the driving valve body to be in butt joint with the driven valve body at the driven end, and filling is completed.
本发明涉及一种高可靠度抱爪式在轨加注机构和方法,加注机构包括主动端和被动端;捕获前,主动端的M个抱爪处于张开状态;当被动端在主动端的捕获范围内时,驱动机构驱动移动板向下运动,移动板通过抱爪轴系拖动抱爪向下直线运动,抱爪在凸轮副相互作用下,逐渐收拢并向下移动,将被动端捕获,之后,抱爪继续收拢至垂直状态,然后抱爪开始垂直运动,将被动端压紧在顶板上;然后抱爪继续垂直向下运动使主动阀体与被动端的被动阀体对接,完成加注。
