为了使攻丝工作变手工为机械化,我们试制成功了一套攻丝夹具,大大减轻了体力劳动,提高了生产效率。夹具结构如附图,由18件组成,计1锥尾、2圆形螺母、3弹簧、4锁紧螺母、5六方螺母、6斜齿帽、7平键、8螺丝、9斜齿套筒、10裁丝、11顶丝、12夹头体、13制动销、14双向螺丝,15、16夹头、17弹簧、18套筒。另外有三个附件,计19六角搬手、20钻套、21扁销。这一夹具装在钻床上使用。将丝攻装入夹头15、16中,用六角搬手19搬动双向螺丝14,夹头即可将丝攻夹紧。攻
In order to change the manual tapping work mechanized, we successfully trial a tapping fixture, greatly reducing manual labor and improve production efficiency. Fixture structure as shown in the figure, consisting of 18 parts, 1 cone end, 2 round nut, 3 spring, 4 lock nut, 5 hexagonal nut, 6 inclined tooth cap, 7 flat key, 8 screw, 9 helical sleeve , 10 wire, 11 top wire, 12 chuck body, 13 brake pin, 14 bidirectional screw, 15, 16 collet, 17 spring, 18 sleeve. In addition, there are three attachments, 19 hex handles, 20 drill sleeves, 21 flat pins. This fixture is used on a drilling machine. The wire tapping into the chuck 15, 16, with a hexagonal handle 19 move two-way screw 14, the chuck can be tapping clamp. attack
