Separation mechanism unlocked based on rotating pressing ring

Abstract

The invention provides a separation mechanism unlocked based on rotating a pressing ring. An upper butt joint ring is rigidly and fixedly connected with an object to be separated; each of the upper butt joint ring and a lower butt joint ring is provided with an inclined plane flange; the upper and lower butt joint rings are tightly pressed together through retracting the pressing ring with a pressing block; a pre-tightening force is applied to the pressing ring through screwing a locking screw, so that a separation surface is tightly pressed. In an unlocking process, a pin of a pin puller is pulled out, and a lock hook rotates under the action of a pushing force of a lock hook leaf spring; one end of a locking lever is released, and the locking lever rotates under the action of a pulling force of the locking screw, so that two ends of the pressing ring are in free states and the pre-tightening force disappears; the pressing ring rotates under the action of the lock hook leaf spring and a rotary spring, and the upper butt joint ring is in a free state and then is pushed out through a separation spring, so that the upper butt joint ring is separated from the lower butt joint ring. The separation mechanism provided by the invention has the advantages that a product has small size, light weight, a small unlocking enveloping space and small impact, and is especially suitable for the fields of satellite-launcher and satellite-satellite separation, and effective load releasing of micro / nano-satellites with the weight of only dozens of, even a few of kilograms, and the like.

Description

technical field [0001] The invention relates to a separation mechanism, in particular to a separation mechanism unlocked based on a rotating pressure ring. Background technique [0002] In the research field of spacecraft separation technology, the development of separation device occupies an important position. The separation device, also known as the separator, is a mechanism for connecting and separating spacecraft, and is widely used in satellite and rocket separation, rocket stage separation, payload release and other fields. As an important part of the spacecraft, the separation device completes two different functions in the working process: during the flight process before separation, the separation device connects the two connected parts into one under the action of a certain load; performs the separation task , to ensure that the two parts being connected can complete the separation action safely and reliably. [0003] In today's aerospace field, most of the sepa...
