Abstract

Изобретение относитс к металлообработке и может быть использовано дл подачи прутковых заготовок а зону обработки металлорежущих станков Цель изобретени - повышение производительности путем использовани одного зажимного механизма дл зажима прутков различного диаметра. Механизм зажима установлен внутри механизма перемещени , выполнен в виде стакана 5 с центрирующим конусом 6 и продольными наклонными пазами 7, взаимодействующими с выпуклыми час- част ми 9 расположенных внутри них гибких элементов 8. Последние св заны с хвостовиком 10, подпружиненным относительно стакана 5, установлены с возможностью перемещени вдоль его оси и кинематически св заны с механизмом перемещени . При движении корпуса 3 вправе двуплечий рычаг плечом упираетс в собачку,.при этом его плечо выходит из зацеплени с ползуном 13. После этого пружина 11 разжимаетс и гибкие элементы 8, взаимодейству с пазами 7, зажимают конец прутка, который зажат механизмом 2 фиксации. Затем гибкие элементы 8 продолжают скользить по торцу прутка до упора последнего в центрирующий конус 6, после чего механизм фиксации разжимаетс и пруток подаетс в шпиндель станка. 1 з.п. ф-лы, 4 ил.The invention relates to metalworking and can be used to feed bar blanks and a machining area for machine tools. The purpose of the invention is to increase productivity by using a single clamping mechanism for clamping bars of different diameters. The clamping mechanism is installed inside the movement mechanism, made in the form of a cup 5 with a centering cone 6 and longitudinal inclined slots 7, which interact with convex parts 9 of flexible elements 8 inside them. The latter are connected with the shank 10, spring-loaded relative to the cup 5, are installed can move along its axis and kinematically associated with the movement mechanism. When the body 3 is moving, the double-arm lever has the right to rest against the pawl, while its shoulder disengages from the slider 13. After that, the spring 11 is released and the flexible elements 8 interact with the grooves 7 and clamp the end of the bar, which is clamped by the fixation mechanism 2. Then, the flexible elements 8 continue to slide along the end of the bar until the latter stops in the centering cone 6, after which the locking mechanism is opened and the bar is fed into the machine spindle. 1 hp f-ly, 4 ill.
