Distance measuring device for debugging of emergency lock system of aircraft canopy

Abstract

The invention relates to a distance measuring device for debugging of an emergency lock system of an aircraft canopy. The distance measuring device comprises a fixed head, a distance measuring head, a screw rod with a gap, a locking nut and scale marks, the end of the fixing head is oblate, and a hole is formed in the middle of the fixing head so that the fixing head can be fixedly connected with an emergency lock of peripheral equipment through a fixing pin. The end of the distance measuring head is oblate, and a hole is formed in the middle so that the distance measuring head can be fixedly connected with the transmission mechanism through a fixing pin; the screw rod with the gap is arranged at the root of the distance measuring head, and the scale marks are manufactured at the gap of the screw rod; and the locking nut is installed on the screw rod with the gap. The center distance between the mounting hole of the emergency lock and the mounting hole of the transmission mechanism is measured and directly read by adjusting the total length of the distance measuring device, and the pull rod is manufactured according to the size, so that main technical parameters such as unlocking stroke of the emergency lock system can meet requirements, the emergency lock system can normally work, and the device is simple and quick to operate.

Description

technical field [0001] The invention belongs to the technical field of aviation equipment, and in particular relates to a debugging distance measuring device for an emergency lock system of an aircraft canopy, which is used for measuring the center distance from a transmission mechanism in an aircraft emergency lock system to an installation hole of an emergency lock. Background technique [0002] The aircraft canopy emergency lock system is an important part of the aircraft ejection life-saving system, which directly determines whether the pilot can be ejected from the aircraft in case of distress in the air, so as to ensure the safety of the pilot's life. When debugging the emergency lock system, it is necessary to replace the pull rods of different lengths and sizes to ensure that the main technical parameters such as the unlocking stroke of the emergency lock meet the requirements and ensure the debugging requirements of the emergency lock system. This type of aircraft i...

AI Technical Summary

Problems solved by technology

This type of aircraft is a trial repair model of the Air Force equipment system. The aircraft has entered the first overhaul period. There is no measurement plan in the system and industry, and it is impossible to accurately measure the center distance between the emergency lock and the transmission mechanism.

If the center distance between the emergency lock and the transmission mechanism cannot be measured, the debugging of the emergency lock cannot be carried out normally, the canopy of the aircraft cannot be repaired, and the combat effectiveness of the Air Force cannot be guaranteed.
