在机器制造工厂中,当车床加工制件时,苏联施工员德列莫夫和阿里钦建议使用自动夹紧的回转式桃形夹头。从附图中可以看出,在桃形夹头的外体1上有镗过的孔,在外体的下部,装有稜柱体3,稜柱体能藉调整螺丝4而在外体中上下移动。在稜柱体的一侧,有一条链槽,螺钉6的尾部即插入稜柱体的键槽内,使稜柱体不能从外体掉出或前后移动。带有偏心的拨杆2,装在螺钉5的轴上,可以任意转动。螺
In machine-building plants, Soviet builders Drimov and Ariqin suggested the use of self-clamping rotary peach collets when machining lathes. It can be seen from the figure that the outer body 1 of the peach collet has bored holes, and the lower part of the outer body is provided with a prism body 3 which can be moved up and down in the outer body by means of the adjusting screw 4. On the side of the prism, there is a chain slot, the tail of the screw 6 is inserted into the keyway of the prism so that the prism can not fall out or move back and forth from the outer body. Eccentric lever 2, mounted on the shaft of the screw 5, can be any rotation. screw
