Abstract

The present invention relates to a sphere polishing machine, comprising: a machine table, and a sphere polishing device; the sphere polishing device is used to polish the sphere while driving the sphere to rotate in all directions; it is characterized in that the sphere polishing machine also includes: The interference member and the first driving mechanism; the first driving mechanism is used to drive the interference member to contact and move away from the surface of the sphere at a preset frequency when the sphere rotates in all directions. The present invention uses a motor to drive the involute cam to move the sphere rotating in all directions at intervals, which increases the complexity of the sphere movement, makes the surface texture of the sphere more irregular, reduces the intermediate frequency error, and improves the surface precision.

Description

technical field [0001] The invention relates to a polishing machine, in particular to a ball polishing machine. Background technique [0002] In precision measuring instruments and the aerospace industry, high-precision spheres are often used. Some precision requirements are below 0.025 μm, and high-precision spheres are mostly key components that play a decisive role in the reliability and life of equipment. Therefore, the research on the precision machining method of the sphere has great practical significance. [0003] At present, among the many processing technologies for high-precision spheres, the more prominent technologies are plane grinding and V-groove grinding, but these two are mainly used for processing spheres with relatively small diameters. For precision machining of spheres with a diameter of 60MM or more , Among the many processing technologies, the one with lower cost and more applications is a processing method of four-axis ball mill.
