自锁式可换头钻头的设计

Design of Self-locking Exchangeable-Head Drill

基于钻削加工理论、弹性理论和自锁技术，并结合整体式钻头和现有可换头钻头的结构，设计了一种新的自锁式可换头钻头。深入解析了其刀头的结构特点，并验证了刀头结构快速安装和锁紧的可行性和合理性。这种新型自锁式可换头钻头的刀头设计对可换头钻头的研究和开发具有参考作用和实用价值。

Based on the drilling theory, elasticity theory and self-locking technique, combined with the structures of integral drill and existing exchangeable-head drill, a new self-locking exchangeable-head drill was designed. The structural characteristics of the cutting head were analyzed, and the feasibility and rationality of the quick installation and locking of this head structure were verified by experiments. The cutting head design of this new drill has the referencing significance and practical value for the R＆D of exchangeable-head drills.
