Description

Изобретение относитс  к станкостроению и может быть использовано дл  гашени  вибраций в металлорежущих станках.The invention relates to a machine tool industry and can be used to dampen vibrations in machine tools.

Цель изобретени  - повышение динамических характеристик путем расширени  возможностей активного демпфировани  эле- ментами несущей системы станка.The purpose of the invention is to increase the dynamic characteristics by expanding the possibilities of active damping by elements of the machine tool carrier system.

На чертеже схематически показано устройство с системой управлени  предварительным нат гом, причем пьезодвигатель прижимает стол к салазкам.The drawing shows schematically a device with a preload control system, with the piezo motor pushing the table against the slide.

Устройство содержит салазки 1 станка, установленные в направл ющих качени  на роликах 2, стол 3 координатно-расточного станка, установленный в направл ющей 4, упругие элементы 5 и систему предварительного нат га, состо щую из ролика 6, обратной планки 7, жестко св занной с салазками , пьезодвигател  8, винта 9 и стойки 10.The device contains a machine slide 1, mounted in roller guides on rollers 2, table 3 of a jig boring machine mounted in guide 4, elastic elements 5, and a preliminary tensioning system consisting of roller 6, reverse plate 7, rigidly connected with a sled, piezodvigatel 8, screw 9 and rack 10.

Устройство работает следующим образом .The device works as follows.

Когда дл  гашени  колебаний в несущей системе станка необходимо создать колебани  стола с определенной амплитудой, частотой и фазой, определенный сигнал, соответствующий требуемым колебани м стола.When it is necessary to create table oscillations with a certain amplitude, frequency and phase, a certain signal corresponding to the required table oscillations in order to damp oscillations in the carrier system of the machine.

подаетс  на управл емую опору, котора , мен   свои линейные размеры, заставл ет колебатьс  стол, причем на прижатие работает сама опора, а на отжатие - энерги , запасенна  в упругих элементах и стыке.It is fed to a controllable support, which, by changing its linear dimensions, causes the table to oscillate, the support itself working on pressing, and the energy stored in the elastic elements and the junction working on squeezing.

При увеличении нат га, когда пьезодвигатель 8 увеличивает свой линейный размер, он соответственно увеличивает силу прижати  стола 3 к салазкам 1. Прижатие происходит через ролик 6, обратную планку 7, винт 9, стойку 10, упругие элементы 5, направл ющую 4 и ролики 2. Поскольку жесткость упругих элементов 5 меньше жесткости данного стыка, путь пройденный столом 3 (S) больше, чем сближение направл ющих S.With an increase in tension, when the piezomotor 8 increases its linear size, it accordingly increases the pressing force of the table 3 to the slide 1. The pressing occurs through the roller 6, the reverse bar 7, the screw 9, the post 10, the elastic elements 5, the guide 4 and the rollers 2 Since the stiffness of the elastic elements 5 is less than the stiffness of this joint, the path traveled by the table 3 (S) is greater than the approach of the guides S.

При сн тии нат га, когда пьезодвигатель 8 уменьшает свой размер под действием управл ющего сигнала, он соответственно уменьшает силу прижати  стола 3 к салазкам 1 через элементы 6, 7, 9, 10, 5, 4 и 2. За счет запасенной энергии в стыке и упругих элементах 5 стол 3 начинает двигатьс  от салазок 1, при этом он оп ть проходит путь больший, чем направл юща  4 стола . Тем самым обеспечиваетс  больша  амплитуда колебаний.When the tension is removed, when the piezomotor 8 reduces its size under the action of the control signal, it accordingly reduces the pressing force of the table 3 to the slide 1 through elements 6, 7, 9, 10, 5, 4 and 2. Due to the stored energy at the junction and the elastic elements 5, the table 3 begins to move away from the sled 1, while again it travels a path more than the guide 4 of the table. This ensures a large oscillation amplitude.
