Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, and more specifically to a blank feeding mechanism for gear processing. Background Art

[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. Gears are mechanical parts with teeth that can mesh with each other. During the gear processing process, large pieces of blanks need to be turned into small pieces according to the outer diameter of the gear to be processed through tools such as lathes, and then the tooth shape is processed through milling, hobbing, gear shaping and other processing methods to shape the turned small pieces of blanks.

[0003] Before the tooth profile processing is carried out on the turned blank, the blank needs to be placed flat on the feed port of the tooth profile processing equipment. The existing blanks are stacked together after turning. When feeding into the tooth profile processing equipment, the blanks are easily discharged and stored vertically, which usually requires manual alignment. Since there are a large number of burrs on the blanks after turning, manual alignment of the blanks is not only inefficient, but also easy to scratch the hands of the staff, posing a great safety hazard.
