Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a grinding and polishing device for mechanical gear processing. Background Art

[0002] A gear is a mechanical component with teeth on a wheel rim that mesh continuously to transmit motion and power. The use of gears in transmissions dates back to the late 19th century. The principle of gear cutting by generating, along with specialized machine tools and cutting tools that utilize this principle, emerged. With the development of production, the smooth operation of gears has become increasingly important.

[0003] At present, gear grinding is to improve the surface quality of gears, eliminate burrs during the processing process, and improve the precision and durability of gears. Commonly used gear grinding tools include grinding wheels, grinding heads, grinders, etc. Gear grinders are equipment specially used for gear grinding, with high precision and a high degree of automation.

[0004] However, the current grinding and polishing devices used for mechanical gear processing can only grind and polish the tooth surface of one side of the gear. After the processing is completed, the gear needs to be manually turned over to grind and polish the tooth surface of the other side of the gear. Since the gear is heavy and inconvenient to pick up, the processing efficiency of the gear is greatly reduced, which is not conducive to batch processing of gears. Utility Model Content
