Embodiment
[0059] The rapid upper plate apparatus and method of the laser gyro cavity of the present invention are used, and the polishing of the upper plate and the reference side surface of the triangular gyro cavity are implemented, and the processed surface of the reference side and the reference side is formed, and the processing of the sticker is performed. Both the surface of the sub-surface need to be polished to 90 ° with the reference side, 120 ° (adjacent to the reference side) or 180 ° (relative time). The technical acceptance of the laser gyrchic cavity after polishing, and the data after the surface of the fitting surface is shown in Table 1. From this, it is understood that the rapid upper disc device and method are employed by the present invention, even if the laser gyro cavity has omitted the pre-machining and optical machining tools, only one reference surface is processed, and the polishing of the subsequent reference side can be quickly and effective. Implementation of t...

Abstract
The invention provides a rapid loading device and method for unconventional laser gyroscope cavity polishing. The rapid loading device for unconventional laser gyroscope cavity polishing comprises a first fine adjustment mechanism and a second fine adjustment mechanism; the first fine adjustment mechanism is used for determining the adjustment amount of a reference side face; and the second fine adjustment mechanism is used for optical cement loading according to the adjustment amount. By means of the loading device, loading of the laser gyroscope cavity on a square brick is implemented, so that efficient and accurate polishing of the reference side face of the gyroscope cavity is met, and even if the crossing procedures of early-stage machining and optical machining are omitted for the laser gyroscope cavity, and only one reference large face is machined, the accurate machining of the pasting face can be rapidly and effectively achieved through polishing of the follow-up reference side face; and conditions are created for efficient machining of the laser gyroscope cavity which is low in cost, small in size and high in precision.
Description
Technical field [0001] The present invention belongs to the field of laser gyro cavity processing, and in particular, the present invention relates to a rapid upper disc device and method for polishing of unconventional laser gyro cavities. Background technique [0002] The laser gyroscope is an instrument that does not depend on external information, nor to external radiant energy, can self-perceive the moving object's yaw angle and position, is a core sensitive device in the inertial navigation system. With the development of inertial technology, the laser gyroscope has caused the laser gyroscope to develop in a small size, high precision and low cost. There are multiple capillaries in the gyro cavity as a laser pathway, and each adjacent two capillaries have an intersection, and a mirror is firmly attached to the plane of each of the intersection points to form a plurality of capillary. The resonant cavity forms a closed loop, which is referred to as a "patch surface". Both th...
