A general test tool for travel switch of launch vehicle

Abstract

The invention relates to a universal carrier rocket travel switch testing tool. The universal carrier rocket travel switch testing tool is operated in cooperation with a plurality of travel switches and comprises a base, a main framework, a card, a fixing portion, a compression nut, a positioning nut, a pressing plate and a threaded rod. The main framework is fixedly arranged on the base, a first through hole is formed in the top of the main framework, and the fixing portion used for fixing the card is fixed onto the main framework. A second through hole is formed in the card. The pressing plate is provided with a plurality of antiskid holes matched with button-shaped protrusions of the travel switches. The travel switches are arranged on the base and located under the pressing plate. The pressing plate is fixed to the lower end of the threaded rod, and the threaded rod sequentially penetrates through the compression nut, the second through hole, the positioning nut and the first through hole from top to bottom. The universal carrier rocket travel switch testing tool achieves the effects that in the integration test stage, contact operation heads of the travel switches can press certain positions for a long time, the testing reliability is improved, simultaneous compression of the two travel switches can be achieved, and the cost and labor force consumption are lowered.

Description

technical field [0001] The invention relates to a test tool, in particular to a universal test tool for a travel switch of a launch vehicle. Background technique [0002] The travel switch is used in the separation surface of the carrier rocket and the separation surface of the rocket and the ground. It mainly uses the docking or separation of the cabin to make the contact move to realize the disconnection or connection of the control circuit, and realize the purpose of sequence control and state control. [0003] In the joint test stage, in order to simulate the real launch and flight status, the contact operation head needs to be pressed to an appropriate position to disconnect the control circuit. At present, during the test process, two special arrow-up operating positions are set up to press the two travel switches respectively, and the travel switches are operated correspondingly when the command command is heard to simulate the on-off of the separation signal. The who...
