摘要:
A chuck (40) includes a body (42) having angularly spaced ribs (166, 168, 170) in a forward cylindrical opening (48) thereof. A locking element (236) is movable within a passage (180) of the body (42), and is formed with a portion (242) which is extendable from the passage (180), through an inboard peak surface (172) of the rib (166) and into the opening (48). An actuator (44) is coupled to the locking element (236) and is biased by a spring (250) to urge normally the portion (242) of the locking element (236) into the opening (48). A bit (62) is formed with a shank (96) with three grooves (100, 102, 104), having pockets (114) formed in their bases, extending axially to a free end (112) thereof. The bit (62) can be manually inserted into the opening (48) of the chuck (40) such that the grooves (100, 102, 104) are located drivingly over at least portions of the ribs (166, 168, 170), respectively. The portion (242) of the locking element (236) is located biasingly within the pocket (114) to lock the bit (62) with the chuck (40).
摘要(中):
卡盘(40)包括在其前部圆柱形开口(48)中具有角度间隔开的肋(166,168,170)的主体(42)。 锁定元件(236)可在主体(42)的通道(180)内移动,并且形成有一部分(242),该部分可从通道(180)延伸通过内侧的顶部表面(172) 肋(166)并进入开口(48)。 致动器(44)联接到锁定元件(236)并被弹簧(250)偏压,以将锁定元件(236)的部分(242)正常推入开口(48)。 位(62)形成有具有三个凹槽(100,102,104)的柄(96),其具有在其基部中形成的凹部(114),其轴向延伸到其自由端(112)。 钻头(62)可以手动地插入卡盘(40)的开口(48)中,使得凹槽(100,102,104)驱动地位于肋(166,168,170)的至少一部分上, 分别。 锁定元件(236)的部分(242)偏置地位于凹口(114)内,以用卡盘(40)锁定钻头(62)。
