Description

(54) МЕХАНИЗМ ПОДАЧ(54) FEED MECHANISM

Изобретение относитс  к станкостроению и может быть использовано в станках и полуавтоматах , например, во фрезерно-центровальных .The invention relates to machine tools and can be used in machine tools and semiautomatic machines, for example, in milling and centering.

Известны механизмы подач подвижных узлов металлорежущих станков, содержащие последовательно установленные на валу, жестко соединенные между собой кулачки, св занны с ведомым звеном. Кулачки могут перемещатьс  в осевом направленииСП.The mechanisms for feeding the movable units of machine tools, containing successively mounted on the shaft, rigidly interconnected cams, connected with a driven link, are known. Cams can move axially towards the SS.

В известном механизме осевое перемещение кулачков приводит к недостаточной жесткости узла; св занные между собой кулачки имеют один цикл работы; переключение с одного кулачка на другой происходит с преодолением сил трений от усили  замыкани  между роликом ведомого звена с кулачками.In the known mechanism, the axial movement of the cams leads to insufficient rigidity of the node; interconnected cams have one cycle of operation; switching from one cam to another occurs with overcoming the friction forces from the closing force between the roller of the driven link with the cams.

С целью упрощени  конструкции и обеспечени  обработки деталей различных типоразмеров в предлагаемом механизме ведомое звено выполнено в виде ступицы установленной в подвижном узле с возможностью nOBOрота . На внешней поверхности ступицы выполнены равномерно расположенные по окружности проущины, несущие ролики, каждый из которых св зан с одним из кулачков, причем проушины по высоте ступицы расположены в соответствии с расположением кулачков на валу.In order to simplify the design and ensure the machining of parts of various sizes in the proposed mechanism, the slave link is made in the form of a hub installed in a mobile node with the possibility of nOBOR. On the outer surface of the hub, there are made uniformly spaced around the circumference of the eyes, carrying rollers, each of which is associated with one of the cams, and the eyes on the height of the hub are arranged in accordance with the arrangement of the cams on the shaft.

На фиг. 1 изображен описываемый механизм , общий вид; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the described mechanism, a general view; in fig. 2 shows section A-A in FIG. one.

Механизм подачи содержит жестко соединенные между собой кулачки 1, каждый из которых имеет определенный цикл работы. Кулачки установлены на общем валу 2 в станине 3. Вращение кулачка передаетс  через цилиндрическую зубчатую пару 4 от привода 5 подач .The feeder contains rigidly interconnected cams 1, each of which has a specific cycle of operation. The cams are mounted on a common shaft 2 in the bed 3. The cam rotation is transmitted through the cylindrical gear pair 4 from the drive 5 feeds.

В столе 6 имеетс  вал 7, на котором установлена ступица 8 с равномерно распределенными по окружности проушинами, в которых установлены ролики 9. Проушины на ступице 8 по высоте расположены в соответствии с-расположением кулачков на валу 2. Ступицу 8 поворачивают на соответствующий угол вручную маховичком 10 через черв чную пару 11.In the table 6 there is a shaft 7, on which a hub 8 is installed with eyelets evenly distributed around the circumference, in which the rollers 9 are installed. 10 through the worm couple 11.

В верхней части вала 7 имеетс  лимб 12, по которому настраивают механизм на кулачок с определенным циклом работы. Ступицу 8 поворачивают тогда, когда ролик 9 находитс  в контакте с каким-нибудь из кулачков 1 на участке высто  рабочего органа. Участок высто  рабочего органа у всех кулачков имеет одинаковый радиус. Дл  того, чтобы во врем  поворота ступицы 8 не проIn the upper part of the shaft 7 there is a limb 12, through which the mechanism is adjusted to the cam with a certain working cycle. The hub 8 is turned when the roller 9 is in contact with one of the cams 1 in the area of the working body. The area of the working body at all cams has the same radius. In order for the hub 8 to rotate, not
