Problems solved by technology
Previous studies have shown that due to vibration, machining errors and other reasons, the coupled cylindrical cam mechanism has functional failures such as sticking in some applications, and this accidental failure cannot be eliminated by reversing the motor, and can only be eliminated by manually dismantling and reassembling.

The invention discloses a nested coupling cylindrical cam interface assembly and a using method thereof. The interface assembly comprises a driving end and a driven end; the driving end comprises a first-stage module and a second-stage module, and the second-stage module is installed in the center of a bottom plate of the driving end; the first-stage module is mounted on the periphery of the driving end bottom plate; the first-stage module comprises a first-stage center block, a latch hook assembly and a first-stage driving ring; the curve groove line type of the first-stage center block is astraight-ascending-straight-descending combination; the curve groove line type of the first-stage driving ring is a rising-vertical combination; the second-stage module comprises a propelling cylinder, a second-stage driving ring and a second-stage center block, and the line type of a curve groove of the propelling cylinder is a straight-rising-straight combination. The transmission process of thedriving end is decomposed into a first-stage transmission process and a second-stage transmission process, and dual-motor driving is adopted. According to the invention, the line type of the curved groove is simplified, the problem of clamping stagnation (function failure) in some application occasions is solved, and the motion determinacy and reliability of an interface connection function are realized.
Description
technical field [0001] The invention relates to a mechanical repeatable connection and separation interface assembly, which belongs to the technical field of spacecraft modular interface design, in particular to a nested coupling cylinder cam interface assembly and a method for using the same. Background technique [0002] With the continuous deepening of human space research, development and utilization, modular design has become a key technology to meet the needs of spacecraft development such as rapid response, extended service life, reduced development and maintenance costs, and reduced risks. The interface is the link between modules and the channel for material, energy and information transmission between modules. Therefore, the modular interface design of spacecraft has attracted the attention of countries all over the world. [0003] In the iBOSS (intelligent Building Blocks for On-Orbit Satellite Servicing) project of Aachen University in Germany, five types of int...
