Problems solved by technology
[0003] Usually, during the satellite comprehensive test process, the travel switch is triggered by the screw thread precession and withdrawal. The thread precession and withdrawal process takes a long time, and it is difficult to simulate the instantaneousness of the separation moment of the satellite and arrow, and when there are multiple travel switches working Under the circumstances, the simultaneity of triggering the limit switch cannot be guaranteed; and the comprehensive test process needs to power on the whole star, and the workers need to be very careful in the process of pressing and releasing the limit switch, and a little carelessness may lead to electric shock and other dangers , leading to low work efficiency, unsatisfactory test results, and even inability to conduct full-process testing

Embodiment Construction
[0035] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0036] Such as figure 1 As shown, it is a schematic diagram of the satellite travel switch pressing tooling model of the present invention. The envelope size of the shape is Φ45mm×50mm, and the material of each part of the tooling can be made of steel or aluminum. The tooling is composed of handle 4, cam 5, support cylinder 1, moving shaft 3, docking piece 2 and corresponding standard parts. The longitudinal axis of handle 4 passes through the upper pin hole of cam 5 and the upper pin hole of support cylinder 1 to connect the three together. A cotter pin 6 is installed at the end of the handle 4 to limit the axial movement of the handle 4, and two set screws 7 are inst...

The invention provides a satellite travel switch pressing tool capable of quick release. The satellite travel switch pressing tool mainly comprises a cam and a support barrel structure, and the structure is simple; the pressing and release process of a travel switch is realized in a mode of applying torque manually, and all components are connected in a standard mode, so that the production of thetool is conveniently realized; secondly, the occupied space of the tool is small, all parts are relatively independent, intermodule interfaces are designed in the standard mode, and other sizes can be designed for the second time, so that the tool has high adaptability in different working conditions; and finally, the clockwise or counterclockwise torque is applied to a handle manually, so that the travel switch can be driven to press and release, i.e. on the premise that the reliability in pressing and release is guaranteed, the working time of a traditional thread precession method is greatly shortened, and the travel switch is quickly pressed and released through instantaneous operation, so that the working efficiency is improved, and the smooth testing process can be guaranteed.
Description
technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a fast-release satellite travel switch pressing tool. Background technique [0002] The function of the satellite travel switch pressing tool is to give a separation signal at the moment of separation of the satellite and arrow to ensure the correct separation of the satellite and arrow. The correctness of the travel switch signal action is of great significance for the correct separation of the satellite and the rocket, and the satellite continues to execute subsequent instructions. [0003] Usually, during the satellite comprehensive test process, the travel switch is triggered by the screw thread precession and withdrawal. The thread precession and withdrawal process takes a long time, and it is difficult to simulate the instantaneousness of the separation moment of the satellite and arrow, and when there are multiple travel switches working Under the circumsta...
