Precise measurement test bed for special-shaped control lever of airplane and use method

Abstract

The invention discloses an airplane special-shaped control lever accurate measurement test bed and a use method, and belongs to the field of airplane accurate assembly debugging measurement. A non-slip mat is arranged below the equipment base, a detachable connector which can be freely replaced is arranged on the fixed support, a matching connector which can be freely selected according to the fixing form of a measured pull rod is arranged on the sliding support, and lengthened connecting rods with different lengths can be freely matched and installed above the fixed support and / or the sliding support. The sliding rail with the groove and the outer side sliding rail are arranged on the two sides of the equipment base and serve as a sliding channel of the sliding support, and a long flat hole is formed in the center of the sliding rail with the groove. A movable pointer is fixed on one side, close to the graduated scale, of the grooved sliding rail and penetrates through the long flat hole, so that visual reading on the graduated scale is facilitated. The graduated scale is fixed on the equipment base, the 0-position scale line of the graduated scale coincides with the central axis of the detachable connector, and the fixed support and the base baffle are arranged at the starting ends and the tail ends of the sliding rail with the groove and the outer side sliding rail respectively. And the sliding roller is mounted at the bottom end of the sliding support through a roller pin shaft.

Description

technical field [0001] The invention belongs to the field of accurate assembly, debugging and measurement of aircraft, and mainly uses a mechanical sliding mechanism measurement device to efficiently and accurately complete the ground pre-assembly length debugging, inspection and measurement of various types of joystick parts of the aircraft. Background technique [0002] Joystick parts are arranged in major systems of flight, such as flight control system, pilot control system, sensor data feedback system, engine control system and hatch release system. Such parts play a vital role in transmitting the control force, data acquisition and feedback in each system, and then realize the full state control of the aircraft and the smooth realization of the functions of each system. Therefore, the ground pre-assembly, detection and adjustment of various types of joystick parts require precise and scientific processes and technological methods. And before the assembly of the releva...

AI Technical Summary

Problems solved by technology

Since the outer profile of the adjustment joints at both ends is arc-shaped, the given required size of the design is the distance between the holes at both ends. It can be seen that it is very difficult to measure and adjust the special-shaped joystick on the ground.

According to the existing operation process and method, it is necessary to place the control rod on the top of the paper, and measure the hole distance by drawing an auxiliary line with a ruler. Although this type of measurement method can meet the assembly error and related requirements, it has relatively low work Efficiency and higher cumulative risk of error
