Description

Technical Field

[0001] This application relates to the field of fuel tank processing monitoring equipment, and particularly to a wall thickness monitoring device for processing the fuel tank of an aircraft thruster. Background Art

[0002] An aircraft thruster needs to use a fuel and an oxidizer to burn in cooperation to release huge energy, so as to achieve the high-speed flight of the aircraft. As an important part of the aircraft thruster, the fuel tank is used to store the fuel and the oxidizer. During the process of the fuel and the oxidizer burning in cooperation to release energy, the fuel tank needs to withstand the test of high temperature. In order to ensure the safety of the fuel tank and the fuel stored inside it, heat insulation treatment is required on the outer side of the fuel tank.

[0003] When heat insulation treatment is carried out on the fuel tank, a heat insulation foam layer needs to be coated on the outer side of the fuel tank. In order to improve the uniformity of the heat insulation foam layer on the outer side of the fuel tank, usually during the processing, it is necessary to monitor the thickness of the heat insulation foam layer in real time.

[0004] The existing wall thickness monitoring devices usually measure the layer thickness of the heat insulation layer by means of ultrasonic waves or lasers, etc. Usually, the monitor is fixedly installed or hinged on a support member for measurement. When measuring fuel tanks of different sizes, it is usually necessary to reinstall the monitoring instrument, and the applicability is poor. Utility Model Content

The output shaft of the flip electric cylinder 51 is hinged to the flip frame 52 away from the end of the flip frame 52, and the flip seat 4 is driven to rotate relative to the support seat 2 by lifting the output shaft of the flip electric cylinder 51, thereby ensuring that the metal layer detector 3 and the laser detector 10 are facing each other. The axis of the fuel tank ensures the accuracy of the detection data. The dial 9 is installed on the flip seat 4 and rotates as it flips. The pointer 8 points to the scale line on the dial 9 to calculate the flip angle of the flip seat 4. When there are protrusions or depressions on the surface of the metal layer of the fuel tank, the first drive motor 61 is installed on the flip seat 4.
