A clamping and releasing device for separating master and slave spacecraft from each other in orbit

Abstract

The invention provides a clamping and releasing device for on-orbit mutual separation of a master spacecraft and a slave spacecraft. The clamping and releasing device comprises a pin puller (7), a pin puller support (12), two springs (8), a pre-tightening bolt support (9), a pre-tightening bolt (10), a thrust spring (4), four polytetrafluoroethylene sliding blocks (32), two door type sliding plate limiting supports (6), a door type sliding plate (2), two tension spring supports (11), a driven separation plate (18), a driving push plate (17), a main installation plate (1) and a thrust spring installation support frame (5). The middle of the main installation plate (1) is provided with a square hole (29). The thrust spring installation support frame (5) is fixed to the square hole (29). One end of the thrust spring (4) abuts against the thrust spring installation support frame (5). The door type sliding plate (2) is clamped in a sliding groove (33). The pin puller (7) is installed on the pin puller support (12). The driving push plate (17) is wrapped in the driven separation plate (18).

Description

technical field [0001] The invention relates to the technical field of on-orbit separation and release of spacecraft, in particular to a clamping and releasing device for the on-orbit separation of master and slave spacecraft. Background technique [0002] With the continuous development of science and technology, human beings have greatly expanded the research field of space science exploration, and the development trend of space physics exploration has reached the era of multi-point, multi-time and space scale, that is, the complex physical process of the earth space is carried out by multiple small satellites or Collaborative observation of separated loads. The separation and release device is a mechanism used on satellites, which can realize safe and reliable clamping of small slave spacecraft of appropriate size in the harsh environment of the launch stage, and then under the action of control signals, after reaching the target orbital height, the main The spacecraft i...

Problems solved by technology

[0018] To sum up, foreign separation and release devices have the following limitations: the square box type separation and release devices that are common abroad, because the square box type separation and release devices are all developed based on the standard cubesat technical requirements, so they are only used in the field of cubesat launch It is universal and cannot adapt to the launch mission of tiny aircraft with special requirements or special external payloads

[0029] The domestic on-orbit release of carrying small satellites is basically a single release, and there is no precedent for multiple controlled separation and release; the domestic on-orbit clamping and releasing device basically does not have a complete set of specially formed structural mechanisms, all of which belong to the belt locking, spring Simple clamp release with actuated, uncontrolled release
