The invention discloses a synchronizing device used for being connected with and unlocking a satellite. The synchronizing device comprises a pair of pin grooves fixedly installed in the two sides of the satellite, and a pair of movable locking pins which are installed on a satellite separation part through a synchronizing drive mechanism and matched with the pin grooves respectively. The synchronizing drive device comprises a base, a supporting rod, a straight pushing rod, a transverse pushing rod and a pair of linkage mechanisms, wherein the base is fixed to the satellite separation part, one end of the supporting rod is hinged to the base, one end of the straight pushing rod is hinged to the free end of the supporting rod, the middle of the transverse pushing rod is hinged to the free end of the straight pushing rod, and the linkage mechanisms are symmetrically arranged on the two sides of the straight pushing rod, correspondingly connected with the movable locking pins and the two ends of the transverse pushing rod and used for transmitting horizontal push force of the transverse pushing rod to the movable locking pins simultaneously so that the movable locking pins can be driven to be separated from the corresponding pin grooves. The synchronizing device is connected with or separated from the satellite through a pure mechanical structure, is simple in structure, convenient to install, stable to work and particularly suitable for taking the place of initiating explosive devices on the ground for satellite separation tests, and greatly reduces experiment cost.
Description
technical field [0001] The invention relates to the connection and separation technology of an aircraft, in particular to a synchronization device for connecting and unlocking satellites. Background technique [0002] With the development of micro-satellites and aerospace technology, it is urgent to develop new connection and separation devices with small size, light weight, low impact or even no impact, so as to adapt to the growing micro-satellites (pico-satellites, nano-satellites) and small launch vehicles. Application requirements. At present, the application of domestic pyrotechnic separation technology is still very extensive. A large number of pyrotechnic products are used in the stage separation, head-body separation and star-rocket separation of missiles and launch vehicles. Foreign countries, especially European and American countries with advanced aerospace technology, have carried out research on separation devices without pyrotechnics, and have obtained prelim...
