The invention discloses an electromagnetic braking cooperation mechanism self-locking navigation inertial unit transposition locking mechanism, and belongs to the technical field of space navigation control, and aims to solve the problems in the prior art that a mechanism toothed disc is stuck and cannot be tested continuously, the failure rate is high, the mechanism test error is large, the mechanism state cannot be freely switched, and the test efficiency is low. The electromagnetic braking cooperation mechanism self-locking navigation inertial unit transposition locking mechanism comprises: a mechanism frame; a transmission shaft system positioned in the mechanism frame and in running fit relative to the mechanism frame, wherein the transmission shaft system at least comprises a first transmission locking shaft, a hollow shaft and a second transmission locking shaft which are coaxially arranged in sequence; a driving self-locking device connected with the end portion of the first transmission locking shaft, wherein driving self-locking and rotation driving of the transmission shaft system are realized through the driving self-locking device; an electronic braking device connected with the end portion of the second transmission locking shaft and used for braking the transmission shaft system; and a high-precision split testing device used for measuring the angle change of a navigation inertial unit in the hollow shaft.

Description

technical field [0001] The invention belongs to the technical field of space navigation control, and in particular relates to a navigation inertial group indexing and locking mechanism which is self-locked by an electromagnetic brake coordination mechanism. Background technique [0002] From the completion of assembly to the launch of the missile, it must be self-calibrated to ensure that the error of the navigation inertial group test data is smaller and the flight direction is more accurate. The inertial group indexing / locking mechanism is an important part of the navigation inertial group self-calibration system. Its function is to control the navigation inertial group to rotate at a specified angle and lock the specified position according to the calibration requirements. With the wide application of space navigation control technology, the current navigation control system is developing towards higher precision, smaller size and lighter weight. [0003] The inertial gr...
