Description

Technical Field

[0001] The present invention relates to the technical field of ceramic ball processing, and particularly to a conical multi-channel three-dimensional cyclic processing device and method for ceramic ball processing. Background Art

[0002] With the rapid development of industrial level, the requirements for the accuracy and reliability of bearing sphere components are getting higher and higher. For mechanical equipment that requires high-precision motion, the accuracy of its bearing spheres largely determines the accuracy and service life of the entire equipment. The extensive use of ball bearings in modern machinery has imposed higher requirements on the accuracy of bearing balls. The accuracy of bearing balls (spherical deviation, ball diameter variation, and surface roughness) directly affects technical indicators such as the motion accuracy, noise, and life of ball bearings, and thus affects the performance of equipment and instruments. Due to the advantages of engineering ceramic materials such as high hardness, low density, high specific stiffness, small thermal expansion coefficient, and stable chemical properties, the bearing balls made of engineering ceramic materials have higher hardness and lighter mass compared with steel balls, making it possible for them to gradually replace steel balls. Such rolling elements have broad application prospects in fields such as heavy vehicles, aerospace, and ships.

[0003] Currently, there are many grinding and processing devices and methods for ceramic balls at home and abroad, such as V-groove grinding method, variable curvature groove grinding method, circular groove grinding method, conical disk grinding method, self-rotation angle active control grinding method, magnetic fluid grinding method, etc. To obtain high-precision balls, it is necessary to meet conditions such as cutting equiprobability and size selectivity during the grinding process. In the specific grinding process, during the grinding process of the sphere in a V-groove, circular groove, etc., the ball blank can only perform a "constant relative orientation" grinding motion, that is, the relative spatial orientation of the self-rotation axis of the ball blank to the public rotation axis is fixed, and the ball blank rotates around a fixed self-rotation axis. To change the adverse effect of this "constant relative orientation" grinding motion on the grinding uniformity of the ball surface, currently, mainly methods such as vibration slipping of the sphere during the grinding process and external auxiliary agitation are relied on to change the self-rotation angle and public rotation angle of the ball. However, the process of changing the self-rotation angle is very slow, and the change in the angle of this self-rotation is limited. During the conical disk grinding process, the self-rotation angle of the sphere will change slowly, and the change range is relatively large; however, due to the fixedness of the grinding disk diameter, the overall change trend of its self-rotation angle is still limited, which is not conducive to uniform, efficient, and high-speed grinding during the ball grinding process. Currently, the main methods for ceramic ball grinding are grinding methods such as V-groove, cone, and eccentric grinding. Each grinding method has certain limitations and cannot combine the advantages of their respective structures.

[0004] In summary, there are still many deficiencies in the current high-precision and efficient ceramic ball grinding and processing methods. To better solve this problem, the structure of the ceramic ball grinding method is optimized and improved. Through a spiral motion structure, the distance between the ceramic ball and the center of the grinding structure during the ceramic ball grinding process is continuously changed, thereby realizing the change of the self-rotation angle of the ceramic ball and improving the processing accuracy.
