Abstract

The invention belongs to the manufacturing technology, and relates to a balance test mould and a test method of a flexible gyroscope inertia rotor component. In the invention, by manufacturing a test mould and improving the test process, an adjusting screw is added to the test mould, the test standard can be strictly controlled, the measurement and control on the moving distance of an inertia rotor relative to a flexible head can be realized, and the accuracy and repeatability of the balance of the inertia rotor component are guaranteed. The test mould can control the clearance between an annunciator and a magnetic conduction surface of the gyroscope rotor within +/-0.005mm, and the gradient consistency of the annunciator is controlled at the magnitude of 10<-3>mV/''; and through the test mould, the test accuracy and the repeatability of the balance of the inertia rotor component can be guaranteed to be 0.02 degrees/h/g and 0.05 degrees/h/g, respectively, thereby being beneficial to the overall performance of the gyroscope.

Description

technical field [0001] The invention belongs to manufacturing technology, and relates to a balance test mold and a test method of a flexible gyro inertial rotor assembly. Background technique [0002] The balance technology of the inertial rotor of the flexible gyroscope (hereinafter referred to as gyroscope) is the key technology in the gyroscope installation and adjustment process. The gyroscope has strict requirements on the rotor unbalance index, which puts forward higher requirements for the test accuracy of the inertial rotor balance. [0003] The balance process of the gyro rotor includes the test and adjustment of the axial unbalance of the rotor and the test and adjustment of the radial unbalance of the rotor. The test accuracy of the rotor balance is relatively high. If the accuracy of the rotor balance is not up to standard, the gyro will drift. degrades the performance of the gyroscope.

AI Technical Summary

Problems solved by technology

[0003] The balance process of the gyro rotor includes the test and adjustment of the axial unbalance of the rotor and the test and adjustment of the radial unbalance of the rotor. The test accuracy of the rotor balance is relatively high. If the accuracy of the rotor balance is not up to standard, the gyro will drift. degrade gyroscope performance

[0004] The balance test mold used in the traditional test method does not have an adjustment screw. The tested gyro rotor is directly placed on the test mold and fixed with tension screws for testing. Due to the processing errors of the parts and the assembly errors of the components, the annunciator The dispersion of the gap from the magnetic surface of the gyro rotor is very large, and this gap directly affects the gradient of the annunciator, and then affects the magnification of the test circuit, which greatly reduces the accuracy of the static balance test of the gyro rotor
