Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and exemplary embodiments.

[0021] A non-destructive detection method for bubbles inside a liquid floating gyroscope, comprising the following steps:

[0022] Step (1): Seal the secondary floating gyroscope to be tested that has been filled with floating liquid, and check that it does not leak oil;

[0023] Step (2): Put the gyro base into the bottom surface of the vacuum tank, place the second floating gyroscope to be tested on the gyroscope base, and expose the bellows assembly of the liquid floating gyroscope to be tested; put the height micrometer into the vacuum tank Inside, and ensure that the probe of the height micrometer is in contact with the bellows cover of the liquid floating gyroscope to be tested, and detect the standard height of the volume compensation components under a standard atmospheric pressure; after the height micrometer is cleared, seal the vacu...

Abstract

The invention relates to a liquid floated gyroscope, in particular to a nondestructive testing method for bubbles in the liquid floated gyroscope, which is used for overcoming the defects that the existing method for testing the bubbles in the liquid floated gyroscope is complicated in operation method and high in data analysis difficulty, and products with bubble hidden dangers cannot be completely removed. According to the nondestructive testing method for the internal bubbles of the liquid-floated gyroscope, high-sensitivity detection of the internal bubbles of the liquid-floated gyroscope is realized by utilizing the volume compensation component height change of the liquid-floated gyroscope caused by the expansion of the internal bubbles of the liquid-floated gyroscope in a vacuum environment, and the nondestructive testing method is simple to operate, easy to implement, suitable for various types of liquid-floated gyroscopes and wide in application range.

Description

technical field [0001] The invention relates to a liquid floating gyroscope, in particular to a nondestructive detection method for bubbles inside the liquid floating gyroscope. Background technique [0002] Liquid floating gyro has a series of advantages such as high precision, strong ability to resist vibration, shock and other mechanical environments, high ability to adapt to environmental temperature changes, small size, light weight, etc., and has been widely used in inertial navigation and inertial guidance systems. The structure of the liquid floating gyro is complex, the assembly precision is high, the internal clearance of the product is small, and the minimum clearance is only on the order of microns. If there are air bubbles inside the liquid floating gyro, interference torque will be generated, resulting in poor drift stability of the gyro. [0003] refer to figure 1 , if there is a bubble 02 inside the liquid floating gyro, due to the uncertainty and instabilit...
