The invention discloses a quick disassembling and assembling connector for spatial operation without a driving source. An annular upper cover of a tool box is fixedly connected with a base plate of the tool box, an upper rail and a lower rail with same location and length are machined on the contact surface of the upper cover and the base plate, and two symmetrical openings are formed in the upper cover of the tool box; the upper cover of the tool box is provided with a locking limit and an unlocking limit; two side lugs are symmetrically installed on the side face of a to-be-disassembled or to-be-assembled tool; the side lugs are assembled in the tool box or disassembled out from the tool box through the openings; the upper ends of the connecting ends of the side lugs and the to-be-disassembled or to-be-assembled tool are provided with locating holes, and the other ends of the connecting ends of the side lugs and the to-be-disassembled or to-be-assembled tool are provided with sliding blocks which can slide along the upper rail and the lower rail; locating rods are fixed at the lower end of a connecting sleeve, the outer side of the connecting end of the side lugs and the tool is sleeved with the connecting sleeve, installation steel balls are evenly distributed in the circumferential direction of the connecting sleeve, the steel balls can move in the radial direction of the connecting sleeve, steel ball grooves are formed in the position, corresponding the steel balls, of the side lugs, the outer sides of the steel balls are sleeved with a locking sleeve, the locking sleeve is connected with the connecting sleeve in a threaded mode, and two locking rotating rods are symmetrically installed on the outer side of the locking sleeve; the number of lifting pins are in accordance with the number of the steel balls, and the lifting pins are evenly distributed and installed on the inner side of the locking sleeve in the circumferential direction.
Description
technical field [0001] The invention belongs to the field of space operation and relates to a fast disassembly interface for space operation without a driving source. Background technique [0002] For various operational tasks of the space manipulator, it is often necessary to replace different end effectors on the rail. Therefore, it is particularly important to maintain a joint interface that is easy to maintain and can realize rapid disassembly-replacement in space. Literature "Research on large-scale space manipulator joints and their vibration suppression control", Harbin: Harbin Institute of Technology master's degree thesis, in 2012, the joint on-orbit quick-change interface was designed, and the quick-change connection pin was used to connect and fasten the interface. Astronauts go out of the cabin to operate the connecting pin, insert it into the pin hole and tighten the nut, the pin will expand and lock the interface; when dismounting, loosen the nut, and the conn...
