Description
Technical Field
The application relates to the technical field of ultra-precision machining, in particular to a cylindrical roller reversing device for a process of polishing and machining a cylindrical surface of a circular biplane.

The bearing is an important and key basic part in the equipment manufacturing industry, directly determines the performance, quality and reliability of important equipment and host products, and is known as a heart part for equipment manufacturing. The precision cylindrical roller is used as a key part of the bearing, and the surface quality (precision, consistency and the like) of the precision cylindrical roller plays an important role in the working performance and the service life of the bearing.
The machining method of the centerless grinding roller has high production efficiency and is easy to realize mass production, but the machining precision of the centerless grinding roller is influenced by the mechanical structure and precision of a machine tool, and the machining of the centerless grinding roller with high precision (national standard 0, I grade) is difficult to realize. The double-plane polishing equipment is used for processing planes at first, and has the characteristics of high processing efficiency and high parallelism after processing because the double-plane polishing equipment can process an upper plane and a lower plane simultaneously, and is widely used in plane processing. Later, biplane polishing equipment was also used to polish machined cylindrical surfaces, such as: a research team led by professor yun julong, an industrial university of zhejiang is used for polishing the cylindrical surface of the cylindrical roller. Practice shows that the processing method for polishing and processing the cylindrical surface by the double planes can meet the requirement of high-precision polishing and processing of the cylindrical surface of the cylindrical roller.
In the double-plane polishing process, the retainer does circular motion, linear velocities of two ends of a cylindrical roller in the retainer are different, if the double-plane polishing process is continued for a long time, the surface processing of the roller is uneven, and the cylindrical roller can be processed into a tapered roller. In order to ensure the processing uniformity of the roller surface, the two ends of the cylindrical roller need to be manually reversed after being processed for a certain time. Because of there being more roller on the processing dish, there is the problem that wastes time and energy in manual switching-over.
