Framework for optical fiber gyroscope and manufacturing method thereof as well as method for packaging optical fiber ring

Abstract

The invention relates to a heat-insulating and vibration-proof framework for an optical fiber gyroscope and a manufacturing method thereof as well as a method for packaging an optical fiber ring. The framework for the optical fiber gyroscope comprises a framework body consisting of an outer wall, an inner wall and a groove bottom; an annular groove is an opening cavity used for mounting the optical fiber ring; the inner side surface and the bottom surface of the annular groove are provided with flame-retardant and heat-insulating and vibration-proof material layers; the material layers are coated with adhesive layers; the adhesive layer at the groove bottom is provided with a lower vibration-proof gasket; an upper vibration-proof gasket is further arranged at the opening at the upper part of the annular groove; the end face of the opening of the annular groove is provided with an optical fiber gyroscope top cover. The manufacturing method comprises the steps of: manufacturing the framework body; processing the flame-retardant and heat-insulating and vibration-proof material layers; coating the adhesive layers and paving the vibration-proof gaskets. The framework for the optical fiber gyroscope has the advantages that the environment temperature and the vibration influence are avoided, framework deformation and a series of errors of the optical fiber gyroscope caused by contact thermal conduction are also avoided, the environment adaptability of the gyroscope is improved, the service life is prolonged; the framework manufacturing method and the method for packaging the optical fiber ring are easy to operate, low in cost, high in efficiency, and stable and reliable in quality.

Description

technical field [0001] The invention relates to a skeleton for a fiber optic gyroscope capable of heat and vibration insulation, a manufacturing method thereof, and a method for encapsulating an optical fiber ring, in particular to a heat-insulation and vibration-isolation skeleton for a medium-to-high-precision fiber optic gyroscope used in a marine attitude or inertial navigation system and Its manufacturing method and packaging optical fiber ring method. Background technique [0002] The fiber optic gyroscope is a device for measuring the angular rate of the carrier relative to the inertial space. It eliminates the disadvantages of the traditional mechanical gyroscope and laser gyroscope. Widely used in navigation, aviation, aerospace, oil exploration and other fields. As a new generation of important inertial measurement devices, medium and low-precision fiber optic gyroscopes have been mass-produced and widely used. However, in medium and high-precision applications s...
