摘　　要：针对小口径炮弹紧口的特点、技术要求以及生产过程中存在的问题,提出一种新的自动紧口方式。通过控制紧口槽的深度和紧口槽的位置,间接地控制小口径炮弹拔弹力的大小,确保紧口后炮弹的拔弹力的一致性;并使用气液增力缸来提供紧口的驱动力,既保证了紧口节拍又减小了设备体积。使用结果证明,该新型紧口装置设计先进、上下料方便,紧口力便于自动调整,拔弹力一致性好,偏差在允许范围内,提高了弹药的品质,保证了杀伤力,有一定的推广价值。A new automatic fastening device is introduced,aiming at the characteristics,techniques and disadvantages of the small-caliber cannonball fasteners.Through an indirect control of the depth and position of the fastening slot,both of the bullet pull strength and its steadiness of the small-caliber cannonball could be defined.An airdraulic reinforcing cylinder is need to drive the fastener,which could maintain the fastening pact and diminish the device volume.Application proves that the new automatic fastening device,whose feeding and blanking is convenient,is advanced design with a steady bullet pull strength and an admitted tolerance.It could also improve the quality of ammunition,ensure its power and could be well popularized.
