The fast welding system of in-orbit maintenance based on biconjugate cam power-assisted principle

Based on the fast welding system of in-orbit maintenance of biconjugate cam power-assisted principle, it is related to the in-orbit maintenance area in aerospace, solves the problems, such as the rapidity of the in-orbit maintenance process of the in-orbit replaceable units of big contact engaging and separating force and the power-assisted to spacefarer.The present invention includes fast plug mounting plate, and fast plug and positioning and guiding pin are each attached on fast plug mounting plate；In-orbit replaceable units, the fast combination hub mounting plate for being fixed on in-orbit replaceable units lower end；Two power-assisted trunnions being separately fixed on the side of in-orbit replaceable units lower end or so two, two power-assisted trunnions are symmetrical about in-orbit replaceable units mass center；It is separately fixed at two servomechanisms of fast plug mounting plate two sides, two servomechanisms and two power-assisted trunnions correspond, stirring two servomechanisms drives power-assisted trunnion to dock fast plug with fast combination hub, and two servomechanisms are rotated by 90 ° the plug for completing in-orbit replaceable units simultaneously.The configuration of the present invention is simple, light weight, it is small in size, be easily installed.
