Pull-out force test device

Abstract

The invention relates to the technical field of mechanical structures and particularly relates to a pull-out force test device. The device provided by the invention comprises a base, a force measuringcomponent, a pull-out linkage component, a first supporting component and a second supporting component. The force measuring component comprises a dynamometer box and a force gauge set in the dynamometer box which is horizontally movably disposed on the first supporting component, a force measuring end of the dynamometer is connected to a hook, and the hook is connected to a separate electrical connector through a flexible rope. The second supporting component comprises a horizontally disposed guide sleeve, the pull-out linkage component comprises a screw and a screw sleeve hand wheel, the screw is arranged in the guide sleeve, one end of the screw is connected with the dynamometer box, the other end is connected to the screw sleeve hand wheel, the screw sleeve hand wheel and the guide sleeve are connected through a circumferential mortise, and the screw sleeve hand wheel is rotated such that the screw drives the dynamometer box to move horizontally until the electrical connector is separated to be disconnected. At this time, the dynamometer displays a separation force value of a separation plug, the operation is easy, the device is safe and reliable, and the test precision is high.

Description

technical field [0001] The invention relates to the technical field of mechanical structures, in particular to a pull-off force test device, in particular to a pull-off force test device for measuring the separation force of an aerospace vehicle separation electrical connector. Background technique [0002] During the flight of modern aircraft, there are separation and dumping actions at all levels to discard fuel-depleted storage tanks. Therefore, aerospace vehicles use a large number of separation electrical connectors, and the performance of separation electrical connectors directly affects the performance of the aircraft. Separate work. However, in recent years, due to the problems of the separation electrical connector itself and the flight quality problems caused by improper assembly operations, the designer systematically put forward the need to test the separation electrical connector and record the separation force during the final assembly process. . [0003] At ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a pull-out force testing device that can improve the assembly quality of the separated electrical connector, provide accurate measured value of the separated force and eliminate the risk of damage to the person and the product, so as to solve the problem of the existing separated electrical connector. The separation force measurement method is not easy to completely simulate the real separation state of the aircraft, there is a risk of injury to the person and the product, and it is difficult for personnel to read accurate tension values
