Problems solved by technology

The above-mentioned patents have the following disadvantages: when the above-mentioned device is fixed to the gyroscope, the fixing screws need to be tightened from three directions. Once one of the fixing screws is not screwed in place, the relative gap between the positions of the fixing arc plates is too large, which may easily cause the axis of the gyroscope to deviate. , resulting in deviations in the final detection data

Abstract

The invention discloses a precision detection device for optical fiber gyroscope production, and relates to the technical field of optical fiber gyroscopes. The problem of axis deviation of an existing detection device is solved. The precision detection device specifically comprises a bottom plate, the outer wall of the top of the bottom plate is fixedly connected with an adjusting assembly, the outer wall of the top of the adjusting assembly is fixedly connected with a locking assembly, the locking assembly comprises a connecting plate and an end frame, the outer wall of the top of the connecting plate is fixedly connected with a cover shell, and the inner wall of the top of the cover shell is fixedly connected with an upper ring. By arranging the locking assembly, a power motor is started to drive an outer gear to rotate, the outer gear is meshed with an outer rack to drive a lantern ring to rotate, then an inner rack is meshed with an inner gear to drive a rotary drum to rotate, and a rotary arm rotates, so that a roller on the inner wall of an end frame is gradually tightened; at the moment, the optical fiber gyroscope is placed in the center area of the locking assembly, and the four power motors synchronously work, so that the roller can be uniformly tightened, and the axis of the gyroscope is prevented from deviating.

Description

technical field [0001] The invention relates to the technical field of fiber optic gyroscopes, in particular to a precision detection device for production of fiber optic gyroscopes. Background technique [0002] The existing precision detection device for the production of fiber optic gyroscopes has the problem of firm fixation when fixing the product. Due to the ring design of the fiber optic gyroscope itself, if the axis of the gyroscope cannot be effectively fixed when clamping the outer wall, follow-up When optical fiber deviation is detected, it is easy to cause inaccurate data, so it is necessary to optimize the design of the fixed components of the existing precision detection device. [0003] After searching, the Chinese patent application number is CN201911267646.5, which discloses a detection device for fiber optic gyroscope production, including a host platform, and a horizontal installation groove is opened in the middle of the top of the host platform, and the ...
