;о ;about

Изобретение относитс  к области технологии машиностроени , а именно к опорным устройствам дл  цилиндрических направл ющих и ходовых винтов металлорежущих станков, и также может быть использовано дл  поддержки цилиндрических заготовок в процессе их обработки, например peзцoвы ш головками.The invention relates to the field of mechanical engineering, in particular to supporting devices for cylindrical guides and chucks of machine tools, and can also be used to support cylindrical blanks during their processing, such as short heads.

. Целью изобретени   вл етс  повышение надежности и точности путем увеличеш1  жесткости ходового винта посредством введеш-   дополнительных опор, имеющих (под действием кинематически св занных с 1ШМИ грузов) возможность перемещегт  совместно с гайкой на заданном рассто нии от нее, определ емым размещенным, на статшне упором.. The aim of the invention is to increase reliability and accuracy by increasing the stiffness of the lead screw by inserting additional supports that have (under the action of kinematically connected with 1SHMI loads) the ability to move together with the nut at a predetermined distance from it, defined by the support.

Па чертеже изображено устройств общий вид.Pa drawing shows the devices overall view.

Опорное устройство содержит ста1мну 1 с выполненным на ее рабочей поверхности продольным направл ющим пазом 2, в котором установлены с возможпос1ыо перемещени  кронигтейиы 3 и 4 с опорными элементами 5 vi б, сопр гаема  поверхность которых имеет возможность взаимодействи  с винтом 7.The support device comprises a stanchion 1 with a longitudinal guide groove 2 formed on its working surface, in which the kronigtei 3 and 4 are mounted with the support elements 5 vi b, the mating surface of which has the ability to interact with the screw 7.

Передвижна  гайка 8 несет на своем корпусе шкивы 9 и 10, черезThe movable nut 8 carries pulleys 9 and 10 in its housing, through

которые перекинуты тросы 11 и 12, . одни концы которых закреплены на конштейнах 3 и 4 соответственно, а к другим подвешены грузы 13 и 14. На Станине 1 также установлен упор 15. Вращение винта 7, а соответственно и передвижение гайки 8, производитс  от двигател  (tie показан ). Устройство работает следующим образом .which are thrown cables 11 and 12,. one ends of which are fixed on brackets 3 and 4, respectively, and loads 13 and 14 are hung on the other. Stand 1 is also mounted on Frame 1. Rotation of the screw 7 and, accordingly, movement of the nut 8, is performed from the engine (the tie is shown). The device works as follows.

При вращении винта, гайка 8 пе .редвигаетс  вдоль его поверхности (направление показано стрелкой), вед  за собой кроштейн 4 с опорнымWhen the screw is rotated, the nut 8 is re-moved along its surface (the direction is indicated by the arrow), leading to the chip 4 with the support

элементом 6, за счет нат жени  троса 12 грузом 14. Кронштейн 3 с опорным элементом 5 при этом стоит на.месте, прижатый за счет нат жени  троса 11 грузом 13 к упору 15.element 6, due to the tension of the cable 12 with the load 14. The bracket 3 with the supporting element 5 while standing on the spot, pressed due to the tension of the cable 11 with the load 13 against the stop 15.

Пройд  упор 15, корпус гайки В, соприкаса сь с кронштейном 3, снимает его с фиксации и продолжает совместное с ним нередвиже ше вдоль винта 7, а кронштейн 4. в свою очередьPassing the stop 15, the body of the nut B, in contact with the bracket 3, removes it from the fixation and continues along with screw 7 along the screw 7, and the bracket 4. in turn

набегает на упор 15 и фиксируетс  в этом положении, предотвраща  прогиб винта.attaches to the stop 15 and locks in this position, preventing the screw from bending.

Использование предлагаемого устройства обеспечивает возможность повы .сить надежность и точность работы ходовых винтов большой длины за счет повышени  их жесткости.The use of the proposed device provides an opportunity to increase the reliability and accuracy of the running screws of a large length by increasing their rigidity.
