Abstract

The invention discloses a connection unlocking mechanism based on worm transmission, and belongs to the technical field of aerospace machinery design. The problems that an existing initiating explosive device can only be used once, large impact can be generated in the acting process of the initiating explosive device and chemical gas released after explosion of the initiating explosive device haspollution are solved. A screw rod is simultaneously arranged on two connecting plates in a penetrating manner, one end of the screw rod is in coaxial non-self-locking threaded connection with a worm wheel, the other end of the screw rod is in threaded connection with a loading nut, the two connecting plates are in close contact through the worm wheel and the loading nut, the worm, the worm wheel and an electromagnet are all arranged on one side of the first connecting plate, the worm is meshed with the worm wheel, a protrusion is fixedly arranged at one end of the worm, and an armature in theelectromagnet is matched with the protrusion in the stretching-out state to achieve circumferential limiting of the worm. The electromagnet is used for replacing the initiating explosive device to serve as a trigger, so unlocking impact is reduced, combustion smoke pollution is avoided, and reusability is high.

Description

technical field [0001] The invention relates to a connection unlocking mechanism based on worm drive, which belongs to the technical field of aerospace machinery design. Background technique [0002] During the launching process of the spacecraft, it is necessary to reliably lock various deployable and detachable devices to ensure that they can withstand the complex mechanical environment during the launch process, and at the same time, they need to be released or separated at an appropriate time to ensure their safety. Able to achieve the intended function. The traditional pyrotechnic separation device will produce a large impact during the actuation process, which will have a great impact on the attitude control of the satellite and sensitive equipment. The chemical gas released after the explosion of pyrotechnics is polluting and will cause damage to precision instruments such as lenses and electronic devices. Also, from a reliability standpoint, pyrotechnics are single...
