Abstract

The invention provides a satellite and rocket separation unlocking actuator. The satellite and rocket separation unlocking actuator comprises an actuator outer cylinder and a tail end cover installed at the lower end of the actuator outer cylinder. A guide seat and a guide frame are mounted in the actuator outer cylinder, a fixed seat is mounted in the guide seat, and a pull pin is mounted in the fixed seat; the guide frame comprises a mounting part matched with the guide seat and a guide column arranged in the mounting part; an elastic piece is mounted on the guide column, and the upper end of the elastic piece is propped against the pull pin; a memory alloy wire used for driving the fixed seat to move is installed in an inner cavity of the guide frame; and an aviation plug for electrifying the memory alloy wire is mounted on the tail end cover. According to the invention, a closed integrated design is adopted, the structure is compact, the integration degree is high, the stability is excellent during pin pulling action, and meanwhile, the tolerance to a complex electromagnetic environment is good, the use and maintenance are convenient, the unlocking speed is high, and the working reliability is high.

Description

technical field

[0001] The invention belongs to the field of aerospace technology, and in particular relates to a spacer and rocket separation and unlocking actuator. Background technique

[0002] The star-rocket separation and unlocking drive facility is generally connected and unlocked by connecting the unlocking device, and the separation movement of the payload and the launch vehicle is realized by separating the energy device. The existing connection and unlocking structure is relatively complicated, and the reliability of use is also low. In particular, the requirements for the processing accuracy and processing technology of the parts are very strict, the processing cost is high, and the processing and manufacturing are difficult. Therefore, it is necessary to improve the separation unlocking mechanism in the existing separation unlocking device. Contents of the invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art,...
