Problems solved by technology

[0004] The technical problem solved by the invention is: Aiming at the problem that the clamping and positioning method at the positioning point is used in the current prior art, the stress at the positioning point is relatively large and cannot adapt to the complex vibration environment, a locking and positioning mechanism for shafting components is proposed, which overcomes the problem of The positioning accuracy of the traditional rotating mechanism is low, and it is difficult to realize the dual-axis locking and positioning function at the same time

Abstract

A shaft assembly locking and positioning mechanism, comprising an outer box body (1), an outer rotating frame (2), an inner rotating frame (3), a first floating shaft assembly (4), and a restraining shaft assembly (5) , the third traveling shaft assembly (7), the locking shaft assembly (6), the fixed-end toothed plate (13), and the locking mechanism (14), through the setting of the fixed-end toothed plate (13), the At the same time, the dual-axis locking and positioning function is completed. This device overcomes the problems of too simple positioning and locking of the traditional mechanism, and the problem of high stress at the positioning position. It can meet the high-precision positioning requirements of the laser pipeline, with tight structure and high stability.

Description

technical field [0001] The invention relates to a locking and positioning mechanism for a shaft assembly, which belongs to the field of high-precision positioning. Background technique [0002] Due to the characteristics of the laser inertial navigation system, the traditional laser strapdown inertial unit requires regular calibration and maintenance, which requires high maintenance and complicated processes. High, put forward the application requirements for the laser strapdown inertial group with the definition of "three self", that is, self-calibration, self-aiming and self-inspection. The "three-self" function means that the laser strapdown inertial group has a dual-axis rotation function, and the self-calibration, self-aiming and self-testing of the laser inertial group can be realized through the rotation modulation of the inner and outer rotating frames. However, the "three-self" laser inertial group requires the inner and outer frames to be absolutely stationary rel...
