Abstract

Изобретение относитс к станкостроению и может быть использовано в автоматизированных станках дл приведени в действие зажимных патронов. Целью изобретени вл етс расширение технологических возможностей за счет обеспечени возможности подачи заготовок через шпиндель . На станине 1 установлена передн бабка 2 со шпинделем 3, на котором установлен патрон 6, механизм зажима которого через систему передач кинематически св зан с полым валом 17, на конце которого выполнен зубчатый венец 22, В стенке шпиндел 3 выполнен проем, в котором с возможностью свободного вращени установлена шестерн 26, кинематически св занна через двойной блок 31-32 с приводом 44. Дл фиксации шпиндел на нем установлена торцова муфта 50. При работе устройства торцова муфта 50 расцепл етс , движение зажима передаетс от привода 44 через двойной блок 31 шестерн м 26 и 22 и далее через полый вал механизму патрона. 1 з.п.ф-лы, 4 ил.The invention relates to a machine tool industry and can be used in automated machines for actuating clamping chucks. The aim of the invention is the expansion of technological capabilities due to the possibility of supplying the blanks through the spindle. On the base 1, the headstock 2 is fitted with a spindle 3 on which the cartridge 6 is mounted, the clamping mechanism of which through the gear system is kinematically connected to the hollow shaft 17, on the end of which a gear crown 22 is made. A free-wheel gear 26 is installed, kinematically coupled through a double block 31-32 with an actuator 44. For fixing the spindle, an end coupling 50 is mounted on it. unit 31 of the double gear 26 and m 22 and further through the hollow shaft chuck mechanism. 1 hp ff, 4 ill.
