Scribing device for aviation transparent glass of airplane

Abstract

The invention discloses a scribing device for aviation transparent glass applied to an airplane, belonging to the technical field of aviation equipment. The scribing device can utilize a telescopic scribing needle, adjusts the shape and position size of the scribing needle according to the shape of a measurement position so as to ensure the scribing accuracy of aviation transparent glass of the airplane. The device comprises a baffle, a sliding block, the scribing needle and a locking screw, wherein the sliding block is arranged on the vertical face of the baffle in a sleeving mode through a clamping groove and can freely slide on the vertical face of the baffle; the scribing needle is in threaded connection with a first threaded hole in the sliding block, and the tip of the scribing needle faces one side of the bottom surface of the baffle; and the locking screw is in threaded connection with a second threaded hole in the sliding block. According to the invention, the telescopic scribing needle can be utilized, the shape and position size of the scribing needle can be adjusted according to the shape of a measurement position, and the scribing accuracy of the aviation transparent glass of the airplane is guaranteed. The extending amount of the scribing needle is adjustable, the vertical face of the baffle is perpendicular to the bottom face, and it can be effectively guaranteed that a scribing size is vertical distance size only by guaranteeing that the bottom face of the baffle is attached to the end face of the aviation transparent glass.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to an aviation transparent glass scribing device for aircraft. Background technique [0002] Aviation transparent glass is an important part of the aircraft life-saving system. Together with the cockpit, it provides the pilot with a good working environment in the air and provides a channel for the pilot to eject from the aircraft. The processing size requirements of aviation transparent parts are the key technical requirements for aircraft repair. It is necessary to ensure that the processing size of aviation transparent parts meets the technical requirements to ensure the repair quality and flight safety. [0003] The typical processing diagram of aviation transparent glass is shown in figure 1 . Such as figure 1 As shown, the glass processing area is arc-shaped, and the thickness of the glass end face is determined by processed to at vertical distance Transiti...

AI Technical Summary

Problems solved by technology

Dimensional errors of marking lines can easily lead to quality problems and affect flight safety

The height of the two teeth of the vernier caliper is the same and cannot be adjusted. In addition, the processing position of the aviation transparent glass is arc-shaped, so the dimension from the marking position to the end surface of the aviation transparent glass is not the vertical distance dimension.
