Description
Technical Field
The invention belongs to the technical field of laser gyroscope cavity processing, and particularly relates to a rapid disc loading device and method for polishing an unconventional laser gyroscope cavity.
Background
The laser gyroscope is an instrument which does not depend on external information and can autonomously sense the yaw angle and the position of a moving object by radiating energy to the outside, and is a core sensitive device in an inertial navigation system. With the development of the inertial technology, the laser gyroscope is promoted to develop towards a small-size, high-precision, low-cost and other directions. The gyroscope cavity is internally provided with a plurality of capillaries as laser channels, every two adjacent capillaries are provided with an intersection point, and a reflector is firmly attached to the plane of each intersection point in an optical cement mode, so that a resonant cavity formed by the capillaries forms a closed loop, and the position is called as a 'patch surface'. The surfaces of the patches are required to be polished to an angle (90 degrees to the large reference surface and 135 degrees to the adjacent reference side surface), defects, surface types and the like meet higher requirements, and therefore the requirements on air tightness and precision of the gyroscope cavity are met. The prior polishing technology is mainly applied to a conventional gyro-a square gyro. Before the surface mount of the gyroscope is polished, two large surfaces and two side surfaces adjacent to each surface mount are in a polished state, and the gyroscope is provided with two reference surfaces, namely a reference large surface (an error in the direction is called a tower direction error) and a reference side surface (an error in the direction is called an angle direction error). And the machining for finishing the state needs to be carried out by penetrating through a fork for multiple times through mechanical machining and optical machining, the machining procedures are multiple, a large amount of manpower and material resources are consumed, and the production cost is very high.
In order to promote the development of the laser gyroscope towards miniaturization, high precision and low cost, an unconventional gyroscope, namely a triangular gyroscope, is developed and the original processing idea is changed. The triangular gyroscope is provided with three capillaries which surround into a regular triangle and are used as laser paths, each two capillaries are provided with an intersection point, and similarly to the conventional gyroscope, the reflecting mirror is firmly attached to the position on the plane of each intersection point in an optical cement mode. The triangular gyroscope omits the fork penetrating procedure of earlier stage mechanical processing and optical processing, and only one reference surface (namely a large reference surface, or a tower-oriented reference surface) needs to be processed in earlier stage, so that the production cost is greatly reduced. However, the reference surface is not sufficient, and the patch surface cannot be polished directly. Before the surface of the patch is polished, a side surface is processed to be used as a reference surface (namely, a reference side surface or an angular reference surface). The processing mode of present ripe benchmark side is the bull polishing mode, and every axle can polish 3 pieces of top cavitys simultaneously, though this mode compares and polishes efficiency in the unipolar and promote to some extent, from cost control such as the outfit of frock, the occupation of polishing equipment etc. and the higher efficiency processing angle, this is not suitable for the triangle-shaped top with characteristics small volume, low cost, high accuracy. The square brick polishing mode can simultaneously polish the reference side surfaces of at least four (such as eight) triangular gyroscope cavities, and has the advantage of high polishing efficiency, but the gyroscope cavities lack the basis for adjusting the angle of the upper plate when the upper plate is polished by the square brick polishing glue, so that the polished side surfaces are difficult to meet the requirements of the reference side surfaces.
Therefore, it is needed to provide a method for quickly loading a top disk for polishing an unconventional laser gyroscope cavity, which can quickly and effectively adjust the top disk angle of the gyroscope cavity when the top disk is loaded on a square brick polishing glue, so as to realize accurate processing after the top disk is loaded on a reference side surface of the gyroscope cavity.
