Device for assembling and positioning inner ring of universal bracket of gyroscope and application of device

Abstract

The invention relates to a device for assembling and positioning an inner ring of a universal bracket of a gyroscope and application of the device and belongs to the technical fields of optical fibersensation and auxiliary devices of navigation gyroscopes. The device comprises a positioning ring, a positioning cylinder and a screw, wherein the positioning ring is integrally connected with the positioning cylinder through inner threads and outer threads in the positioning cylinder; and the screw is mounted at the rear part of the positioning cylinder. According to the device, the outer ring and the spherical surface of the universal bracket are reliably positioned through the positioning ring and the positioning cylinder, the rotation freedom degree of the outer ring is also limited by inward axial force generated by cooperation, then the inner ring can be easily assembled, the axial gap of the inner ring can be adjusted, and the problems that mounting position holes of the inner ringand the outer ring are not easily aligned as the outer ring of the universal bracket is rotated around an axis, a screw shaft is not easily mounted in a penetration manner, and the axial gap of the rotating shaft of the inner ring cannot be adjusted, can be solved.

Description

technical field [0001] The invention relates to an assembly and positioning device for an inner ring of a universal bracket for a gyro and an application thereof, belonging to the technical field of optical fiber sensing and navigation gyro auxiliary devices. Background technique [0002] Small gyro equipment has been widely used in military and civilian fields. The assembly quality of the universal bracket in the gyroscope directly affects the overall rotation flexibility, smooth operation and rotation accuracy of the gyroscope. The smaller the size of the gyro gimbal, the more difficult it is to assemble. Because of the small size, special structure and high assembly precision of the gimbal in small gyroscopes, the actual assembly is difficult and difficult to operate and adjust. [0003] Existing gimbal components such as figure 1 As shown, in the II-II axial direction, bearings are installed on the upper and lower sides of the bracket, the outer ring is installed in th...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defects existing in the prior art, the object of the present invention is to provide a kind of gimbal inner ring assembly and positioning device for gyroscope and its application, through the device The outer ring of the universal bracket is constrained to a fixed position, which solves the problems that the installation position holes of the inner ring and the outer ring are not easy to align, the screw shaft is not easy to wear, and the axial clearance of the rotating shaft of the inner ring cannot be adjusted. It is especially suitable for the universal bracket The inner ring, outer ring and screw shaft of the component are relatively small in size, the inner ring is not easy to assemble, and the axial clearance of the inner ring cannot be adjusted
