Processing Method of Gearbox with Non-Circular Gear Train and Its Application in Rice Potted Seedling Transplanting Mechanism

A non-circular gear train has the advantages of compact structure, easy to achieve dynamic balance, and is often used drive an end-effector complex trajectory attitude. The gearbox key component train, which requires high precision each wheel shaft hole its relative position. Conventional methods use numerical control process tools with train. processing cost too high, there are some problems, such as deflection it can be difficult ensure phase This research proposed a method developed corresponding combination tool. Taking rice potted seedling transplanting mechanism example, special cutting tool five boring was designed holes at one clamping, greatly improve efficiency accuracy processing. processed other parts were assembled into conduct performance experiment. results show that satisfies requirement accuracy, accurately complete picking, transporting, planting, series actions. suitable for large-scale manufacturing mechanism. In this research, aiming double arm high-speed transplanting, analyzed, proposed.
