Universal testing tool for three-axis gyroscope

Abstract

A universal testing tool for a three-axis gyroscope comprises a tool body, switching supports and pressing blocks. The tool body is of a hexahedron structure, stepped holes used for gyroscope installation are formed in the three perpendicular faces of the tool body respectively, through connection support fixing holes, gyroscope positioning holes of different specifications and pressing block fixing columns form a set of positioning structures, and the multiple sets of positioning structures are evenly distributed in the circumferential direction of the stepped faces used for gyroscope installation. The step holes of the tool body are used for positioning gyroscopes with different specifications; the switching supports are matched with the switching support fixing holes, the gyroscope positioning holes with different specifications and the mounting holes in the gyroscopes, and are used for fixing the gyroscopes; and each switching support corresponds to one pressing block used for locking the switching support. According to the universal testing tool for the three common gyroscopes, the testing of the three different types of gyroscopes can be completed by using one tool body without designing an independent tool, so that the time is saved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of fiber optic gyroscope testing, and in particular relates to a test tool used in fiber optic gyroscope speed testing. Background technique [0002] With the development of the aerospace industry, the demand for inertial units continues to increase, and the requirements for the safety performance of inertial units are also continuously improved. [0003] The fiber optic gyro combination is a sensitive device, which is used to sense the inertial angular velocity of the carrier, output its component on the body coordinate system, and provide continuous three-axis inertial angular velocity information for each working mode and flight stage of the carrier. The main functions completed by the fiber optic gyro combination are: measuring the three-axis angular velocity information of the carrier and transmitting it to the carrier system through the interface; providing telemetry signals of important internal state...

AI Technical Summary

Problems solved by technology

Under the current circumstances, when testing gyroscopes, gyroscopes of various specifications need to be individually designed for testing tooling. From the perspective of design, production, and use, one is that there are many types of gyroscopes, and each type of gyroscope testing tooling is a dedicated tooling. , The processing cycle is longer; Second, the cost of using special test tooling for each specification of gyroscope is relatively high, because the special gyroscope test tooling can only be applied to this type of gyroscope, after the test of this type of gyroscope is completed, it cannot be applied to other types of gyroscopes The gyro can only be placed in the tool rack, causing a waste of resources

Especially when the gyro combination production is completed but the test tooling has not been processed, each gyro test tooling cannot be used universally and cannot be exchanged or borrowed. At this time, not only the production cycle is delayed, time is wasted, but also manpower is wasted
