Problems solved by technology

However, since the rocker arm has no working stop after the switch device of the interlock mechanism is turned on, that is, the end point of the rocker arm movement stroke does not coincide with the mechanical unlocking position, the rocking arm will not stop after the mechanical unlocking is turned on. Therefore, the method of directly measuring the working stroke of the rocker arm with a vernier caliper has the disadvantage of large measurement error

Abstract

The invention relates to a measuring device and a measuring method for interlocking mechanism endless travel. The measurement method includes one: after adjusting the position of the helical sleeve to face and close to the rocker arm of the product under test, fixing the measuring device on the product under test; two: adjusting the helical sleeve to make it contact with the product under test. The rocker arm is in a critical state of contact and not moving, and the vernier caliper measures the distance L1 from the lower end surface of the positioning nut to the upper end face of the main body; 3: Adjust the screw sleeve to gradually lift up the rocker arm to the mechanical unlocking state and stop the adjustment instantly, and the vernier caliper Measure the distance L2 from the lower end surface of the positioning nut to the upper end surface of the main body; four: obtain the working endless stroke L=L2‑L1. The invention solves the problem that the interlocking mechanism has no stop point and cannot be accurately measured; it has the advantages of accurate measurement and high efficiency.

Description

technical field [0001] The invention relates to the technical field of aircraft maintenance and measurement, in particular to a device and method for measuring an endless stroke of an interlock mechanism. Background technique [0002] At present, when the interlock mechanism of the aircraft rocket ejection seat is manufactured and repaired, it is necessary to measure the working stroke of the rocker arm in the interlock mechanism. The function of the rocker arm is to connect the switch device in the interlock mechanism. And transmit the electric signal to start the system to work. Its working stroke determines whether the switch device in the interlock mechanism can be connected and the timing of connection. Its parameters determine whether the ejection work link of the rocket seat is continuous and effective, such as the interlock mechanism is connected. If the rocker arm cannot meet the specified working stroke, it may lead to serious consequences that the rocket ejection ...
