Description

Изобретение относитс к электрофизическим и электрохимическим методам обработки и, в частности, к устройствам где используетс прокачка рабочей жидкости.The invention relates to electrophysical and electrochemical processing methods and, in particular, to devices where pumping of working fluid is used.

Известно устройство дл электрохимической обработки с вибрирукицим электродом-инструментом, закрепленным в электрододержателе, включающее заполн емую рабочей жидкостью камеру , св занную с межэлектродным зазором посредством трубопровода llНедостатком известного устройства вл етс сложность конструкции и обслуживани , поскольку дл получени импульса давлени необходима специальна электрическа схема управлени . Кроме того, синхронизаци импульсов давлени с положением электрода-инструмента представл ет определенную трудность.A device for electrochemical processing with a vibrating electrode electrode attached to an electrode holder is known, which includes a chamber filled with a working fluid and associated with an interelectrode gap through a pipeline. In addition, the synchronization of the pressure pulses with the position of the tool electrode presents a certain difficulty.

Цель изобретени - упрощение конструкции устройства.The purpose of the invention is to simplify the design of the device.

Поставленна цель достигаетс тем, что устройство содержит заполн емую рабочей жидкостью камеру, св занную с межэлектродным зазором посредством трубопровода, причем одна из стенок камеры выполнена в виде мембраны, жестко св занной с электрододержателем , а трубопровод выполнен с регулируемым сечением.The goal is achieved by the fact that the device contains a chamber filled with working fluid, connected to the interelectrode gap through a pipeline, one of the chamber walls being made in the form of a membrane rigidly connected to the electrode holder, and the pipeline is made with an adjustable cross section.

Жестка св зь .гибкой мембраны с электрододержателем обеспечивает строгую синхронизацию изменени объема камеры с движением ЭЙ, что упрощает настройку устройства и обслуживание .A rigid connection between the flexible membrane and the electrode holder ensures that the volume change of the chamber is strictly synchronized with the HY motion, which simplifies device setup and maintenance.

Наличие трубопровода с регулируе10 мым гидравлическим сопротивлением (например, дроссель измен емого сечени ) расшир ет технологические возможности так как становитс возможным плавно регулировать порцию The presence of a pipeline with adjustable hydraulic resistance (for example, a choke of variable cross section) expands the technological possibilities as it becomes possible to smoothly adjust the portion

15 вводимой в- МЭЗ рабочей жидкости, что необходимо при обработке различных по площади поверхностей; регулировать скорость изменени давлени во времени и синхронизировать подвод 15 of the working fluid introduced into the MEP, which is necessary when processing surfaces of different area; adjust the rate of pressure change over time and synchronize the supply

20 импульсов давлени с изменением НЭЗ.20 pressure pulses with an NEL change.

Устройство состоит из корпуса 1 с камерой 2, привода вибратора 3, The device consists of a housing 1 with a camera 2, a drive vibrator 3,

25 отделенного от камеры 2 гибкой мембраной 4, штока 5 с электрододержателем 6, а также трубопровода 7 с клапанст 8.25 separated from the chamber 2 by the flexible membrane 4, the rod 5 with the electrode holder 6, and also the pipeline 7 with the valves 8.

Устройство работает следующим The device works as follows.

Claims

30 way. The working fluid, such as an electrolyte, is pumped from the hydraulic connector of the machine to chamber 2 and through conduit 7 and valve 8 to the ORE. The drive of the vibrator 3 (in this case, electromechanical) oscillates the rod 5 with the electrode holder 6. The rod 5 is also connected with the membrane 4 and during oscillations it deflects it from the neutral position. When the rod 5 moves downward, the membrane 4 bends outward, while increasing the chamber junction.

2. This increase in volume is replenished with a certain portion of electrolyte from the hydraulic system of the machine. When the stem 5 moves upwards, the membrane 4 folds inward of the chamber 2, thereby reducing its volume. A portion of the electrolyte is displaced through conduit 7 in the MPA / intensively to remove and remove treatment products from it. The bypass valve 8 regulates the size of this portion, which is necessary when processing various areas. The use of the invention allows to intensify the washing of the MEP and the removal of processing products from it due to the strict synchronization of the displacement of the membrane and the deformation of the membrane, to simplify the design due to the absence of a control circuit and to expand the technological capabilities of the device due to the introduction of adjusting the portion and flow rate of the working fluid. Apparatus of the Invention A device for electrochemical processing with pumping a working fluid through an interelectrode gap, provided with a vibrating electro-tool, mounted in an electrode holder, including a chamber filled with a working fluid, connected to a telescopic gap by means of a pipeline, in order to simplify the design, one of the walls of the chamber are made in the form of a membrane and are rigidly connected with the electrode holder, and the pipeline is made with an adjustable cross section.
