Abstract

The invention belongs to the technical field of hard and brittle material accurate machining, and particularly provides a hemispherical resonator inner spherical surface accurate grinding wheel whichis used for accurate grinding machining of a quartz resonator inner spherical surface and comprises a machining section and a clamping shaft. The machining section comprises a cylindrical section, anarc section, a fillet section I and a fillet section II, the cylindrical section is higher than the minimum-diameter section of a central rod on a quartz resonator, grooves are machined in the surfaces of the arc section, the fillet section I and the fillet section II, the arc section is of an eccentric structure, the fillet section I and the fillet section II are not concentric, a counter bore ismachined in the bottom end of the machining section in the direction of the rotation axis, and the end, away from the machining section, of the clamping shaft is chamfered. Compared with a traditional machining method, the accurate grinding wheel is high in machining efficiency and simple in machining method, and machined parts are free of surface defects and high in quality and precision.

Description

technical field [0001] The invention relates to a hemispherical resonator internal spherical fine grinding wheel, which belongs to the technical field of precision processing of hard and brittle materials. Background technique [0002] Hemispherical resonant gyroscopes are widely used in aircraft navigation equipment, space probes, deep space exploration and remote sensing due to their advantages of light weight, high reliability, high stability, long life and good shock and vibration resistance, radiation resistance and temperature performance. Precision orientation fields such as satellites. As the key core device of the hemispherical resonator gyroscope, the processing quality and precision of the quartz resonator directly affect the performance and quality factor Q of the hemispherical resonator gyroscope. One of the keys to improving the working precision of the hemispherical resonator gyroscope is to improve the processing quality and precision of the quartz resonator...
