[0003] On the one hand, due to the complex structure of shaft parts, drilling, chamfering, and tapping cannot be completed in one go, resulting in low processing efficiency and high manufacturing costs. On the other hand, while splitting the processing steps can solve the problem to some extent, quality supervision during the processing becomes a major challenge, making it impossible to guarantee the consistency of drilling and chamfering, thus affecting product quality. Utility Model Content

[0004] This utility model addresses the problems existing in the processing of shaft parts in the prior art by providing an automated drilling and tapping device for valve rocker arm shafts, aiming to improve processing efficiency, reduce costs, and ensure consistent product quality.
