Three-arm type noncooperative target docking mechanism

三臂型非合作目标对接机构

Abstract

三臂型非合作目标对接机构,它涉及一种卫星对接机构。本发明的目的是为解决现有卫星对接机构对接成功率比较低,且对运动精度要求极高的问题。本发明三个机械臂大臂呈120°角设置在支撑平台的周边上,机械臂大臂的一端与支撑平台铰接,机械臂大臂的另一端与机械臂小臂的一端铰接,机械臂小臂的另一端与末端执行器相连接,每个缓冲柱的下端均与支撑平台的上端固定连接,每个缓冲活塞的自由端均与目标对接平台的下端固定连接。本发明当对接机构到达预定位置后,三个机械臂与目标对接平台构成了封闭区域来包络喷管,这样就使喷管处在一个无法逃脱的空间内,由三个机械臂下压与目标对接平台上推来卡紧、固定目标飞行器。
The invention discloses a three-arm type non-cooperative target docking mechanism, relating to a satellite docking mechanism. The invention aims at solving the problems that the docking success rate of the existing satellite docking mechanism is comparatively low and the requirement on motion precision is extremely high. The three large mechanical arms of the invention are arranged on the periphery of a supporting platform at a 120 degree angle, one end of the large arm of the mechanical arm is articulated with the supporting platform, the other end thereof is articulated with one end of the small arm of the mechanical arm, and the other end of the small arm of the mechanical arm is connected with an end effector; the lower end of each bumper post is fixedly connected with the upper end of the supporting platform, the free end of each dashpot plunger is fixedly connected with the lower end of a target docking platform. In the invention, when the docking mechanism reaches a preset position, the three mechanical arms and the target docking platform form a closed region to encase a jet pipe, therefore, the jet pipe is placed in an inescapable space, and a target aircraft is clamped and fixed by the underdraught of the three mechanical arms and the upthrust of the target docking platform.
