Embodiment Construction

[0052] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0053] The difficulty of processing the logarithmic curve spiral groove of the convex hemisphere lies in the control of the groove depth. During ion etching, the ion beam is projected from one direction to the surface of the convex hemisphere in a straight line, and the convex hemisphere is driven by the tool to rotate around its axis at a certain speed. In this way, a plurality of spiral grooves evenly distributed on the entire spherical surface of the convex hemisphere can be etched. Based on this, the present invention provides a mask for processing the convex hemisphere of the gyro motor, which is used for processing...

Abstract

The invention provides a mask for processing a convex hemisphere of a gyro motor and a processing method thereof, which solves the problem that the processing tooling of the existing convex hemisphere cannot guarantee the processing accuracy of the convex hemisphere and further affects the performance of the gyro motor. The mask for processing the convex hemisphere of the gyro motor comprises a mounting sleeve, a hemispherical shell and an extension sleeve; A logarithmic curve spiral hole matching the shape of the logarithmic curve spiral groove of the convex hemisphere; the processing method for processing the mask of the convex hemisphere of the gyro motor provided by the invention comprises the following steps: step one, preliminary processing; step two 1. Processing positioning mandrel and positioning fixture; Step 3, processing the outer spherical surface; Step 4, CNC milling and processing logarithmic curve spiral hole; Step 5, removing burrs from the outer spherical surface; Step 6, separating mask processing parts and positioning mandrel; Step 7. Deburring the inner spherical surface.

Description

technical field [0001] The invention belongs to the field of gyro motors, and in particular relates to a mask for processing a convex hemisphere of a gyro motor and a processing method thereof, in particular to a mask for ion etching of a hemisphere hemisphere of a dynamic pressure air bearing gyro motor convex hemisphere spiral groove and the same processing methods. Background technique [0002] The three-floating gyroscope is a small gyroscope with the highest precision and the longest life among the electromechanical gyroscopes at home and abroad. It is mainly used in the fields of inertial navigation such as satellites, manned and cargo spacecraft, and space stations. The dynamic pressure gyro motor is the "heart of the three-floating gyroscope." ”, which plays a vital role in the performance and life of the three-floating gyro. [0003] The dynamic pressure air bearing is the key component in the dynamic pressure gyro motor. The dynamic pressure effect and air film st...
