Problems solved by technology
The surface area of the patch is not large, and the mounting positions are all within the range of the optical glue, which cannot be avoided
In addition, the traditional optical processing process is grinding and polishing with granular abrasives. During the optical processing process, the friction between the polishing mold and the granular abrasives on the surface of the cavity is large, and the extrusion clamping method must be used for clamping and fixing. However, if the clamping process is in the There are tiny particles on the fixture and the clamping surface, and it is easy to form a Hertz cone embedded in the cavity and deeply scarred after being squeezed and locked.
And in the process of loading and unloading in the optical processing work, it is very easy to cause scratches on the other surfaces of the tooling and other equipment, resulting in secondary damage to the polished surface, directly affecting the surface defects on the optical surface of the cavity, which greatly Affect processing efficiency

Embodiment Construction
[0024] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] The invention provides a method for overall protection of a space three-axis laser gyro cavity, which belongs to the overall protection tooling technology of a space three-axis laser gyro cavity, and is mainly used in the grinding and polishing stage of a polyhedron space three-axis laser gyro cavity. The protective tooling forms the overall protection of the optically processed surface of the spatial three-axis laser gyro cavity. Such as figure 1 As shown, the space three-axis laser gyro cavity is a space three-axis cavity, which is a 26-sided body, and the angles of each two sides all form different angles at the spatial position: 45°, 35.3° or 90°; the method designs a Protective tooling, which forms an over...

The invention relates to an integral protection method for a space three-axis laser gyro cavity, and belongs to the technical field of space three-axis laser gyro cavities. The integral protection method can be used for wrapping protection of a completed optical surface to effectively avoid the surface breakage and other damage which are caused by an extrusion-type locking manner to existing tooling. The assembly can achieve molding at one time and is easy to operate, which reduces the requirements of blocks on a surrounding environment, and reduces the damage risk of block processing surfaces to reduce the number of rework. The method is suitable for a mass production process.
Description
technical field [0001] The invention relates to the technical field of a space three-axis laser gyro cavity, in particular to an overall protection method for a space three-axis laser gyro cavity. Background technique [0002] Due to the particularity of the shape of the three-axis cavity in space, it is a 26-hedron approximate to a sphere, and the 6-sided patch surfaces are orthogonal to each other during the optical processing process, and there are also two patch surfaces during the optical processing of the electrode surface. Sandwich. The surface area of the patch is not large, and the mounting positions are all within the range of the optical glue, which cannot be avoided. In addition, the traditional optical processing process is grinding and polishing with granular abrasives. During the optical processing process, the friction between the polishing mold and the granular abrasives on the surface of the cavity is large, and the extrusion clamping method must be used...
