    • ABSTRACT OF THE DISCLOSURE A collet and lock nut assembly (10) includes a collet (12) for receiving a cutting tool shank (16) and a lock nut (14) for creating a gripping force between the collet (12) and the shank (16). The collet (12) has a nose portion (24) and a body portion (26) separated by an annular groove (28). The lock nut (14) has a concentricbore (48) with a plurality of retention tabs (72) and a corresponding number of clearportions (74). The collet and lock nut assembly (10) can be easily assembled by inserting at least one retention tab (72) within the groove (28) of the collet (12), and then applying pressure to the collet (12) such that the remaining retention tabs (72) of the lock nut (14) are received within the groove (28) of the collet (12) to place the assembly (10) in a locked position. The collet (12) and cutting tool shank (16) can be drawn from the tool holder (18) by applying rotational torque to the lock nut (14). The collet (12) is easily removed from the lock nut (14) by applying pressure in any circumferential, lateral direction against the collet (12).
    • 发明内容一种夹头和锁紧螺母组件(10)包括用于容纳切割工具柄(16)的夹头(12)和用于在夹头(12)和柄部(12)之间产生夹紧力的锁紧螺母(14) 16)。 夹头(12)具有鼻部(24)和由环形凹槽(28)分开的本体部分(26)。 锁紧螺母(14)具有带有多个保持突片(72)和相应数量的清理部分(74)的同心圆孔(48)。 通过在夹头(12)的凹槽(28)内插入至少一个保持凸片(72),然后向夹头(12)施加压力,使得夹头和锁紧螺母组件(10)能够容易地组装, 锁定螺母(14)的保持突片(72)被容纳在夹头(12)的凹槽(28)内,以将组件(10)放置在锁定位置。 通过向锁紧螺母(14)施加旋转扭矩,夹头(12)和切割工具柄(16)可以从工具夹具(18)中拉出。 通过在任何圆周方向上向压头(12)施加压力,容易地将夹头(12)从锁紧螺母(14)移除。
