Abstract

Изобретение относитс  к станкостроению и может быть использовано в крупных точных станках различных типов, преимущественно в крупных координатно-расточных станках, в которых при перемещении подвижного узла на значительный ход необходимо обеспечить повышенную виброустойчивость и жесткость механизма подач дл  достижени  высокой точности выхода на заданное положение. Цель изобретени  - повышение надежности и упрощение конструкции устройства за счет отсутстви  дополнительных энергетических систем дл  управлени  промежуточными опорами винта. При вращении ходового винта 3 гайка 9 вместе с кулачком 10 и подвижным узлом 1 перемещаютс  по неподвижному узлу 2. При подходе к первой промежуточной опоре 8 гайка 9 своим кулачком 10 наезжает на выступ 17 фиксатора 15, освобожда  промежуточную опору 8 от фиксации. При дальнейшем перемещении гайка 9 наезжает на промежуточную опору 8 и поворачивает ее. После прохождени  гайкой 9 промежуточной опоры 8 она возвращаетс  в исходное положение под действием пружин 13. 1 з.п.ф-лы, 3 ил.The invention relates to machine tools and can be used in large precision machines of various types, mainly in large coordinate-boring machines, in which when moving a movable assembly for a considerable stroke, it is necessary to ensure increased vibration resistance and rigidity of the feed mechanism in order to achieve high accuracy of the output to the specified position. The purpose of the invention is to increase the reliability and simplify the design of the device due to the absence of additional energy systems for controlling intermediate propeller supports. When the spindle 3 rotates, the nut 9 together with the cam 10 and the movable unit 1 move along the fixed unit 2. When approaching the first intermediate support 8, the nut 9 with its cam 10 hits the protrusion 17 of the retainer 15, releasing the intermediate support 8 from locking. Upon further movement of the nut 9 runs into the intermediate support 8 and turns it. After passing through the nut 9 of the intermediate support 8, it returns to its original position under the action of the springs 13. 1 C, ff, 3 sludge.
