A synchronous release tooling for on-board disconnect switch

Abstract

The present invention is a tool for synchronous release of separation switches on a star, the tooling includes a mounting bracket, a guide rod, a pressure plate, a knob, a spring, and a nut; the mounting bracket is provided with a mechanical interface with a separation switch, and four separation switches can be installed at the same time; The rod has an interface with the mounting bracket; the hole on the pressure plate passes directly through the shaft of the guide rod; the spring also has an interface with the guide rod and the pressure plate; when installing, it cooperates with the fixed column between the pressure plate through the slide groove of the guide rod ;The knob has a threaded hole for connecting with the guide rod, and the outer surface is knurled and trimmed; the roughness of the contact surface between the knob and the pressure plate is better than Ra1.6. After the separation switch is installed on the mounting bracket, the pressure plate is pressed down by rotating the knob, and the pressure plate moves down to realize the simultaneous compression and separation of the four separation switches, and the synchronous release is guaranteed by matching the size with the limit.

Description

technical field [0001] The invention relates to an auxiliary tooling for the synchronous release of separation switches on a satellite, which can be used for the synchronous release action of four separation switches of a satellite during the mold flight process, so as to ensure the synchronization of the release of the separation switches in the test process. Background technique [0002] The 4 separation switches (type 2KX-1A, etc.) on the satellite are installed at specific positions on the satellite. After the satellite is docked with the carrier adapter, the movable part of the separation switch will be compressed by the corresponding position of the carrier adapter. When separating, the four separation switches are released at the same time, and the moment the separation switch is released, an electrical signal is generated to feedback the completion of the separation action. During the development process of the satellite, it is necessary to carry out the test of simu...

AI Technical Summary

Problems solved by technology

The separation switch has a compression stroke of (4±0.5) mm, a full stroke of (5±0.3) mm, and a full stroke force of ≤20N. Due to the configuration of the entire star, the 4 separation switches are distributed in different positions of the entire star. They can be directly pressed manually with the help of simple tooling. The tightness does not meet the synchronization requirements, and there is also a risk of colliding with the stars during operation
