Description

Изобретение относитс к машиностроеншо и может быть использовано при создании оборудовани ал электрохимической с рабочими подачами катода-инструментй 0,ОО5-1,0 мм/мин, например дл обработки поверхностей тел вращени и при обработке больших поверхностей .The invention relates to mechanical engineering and can be used to create electrochemical equipment with working feeds of tool cathode 0, OO5-1.0 mm / min, for example for surface treatment of bodies of revolution and for processing large surfaces.

Известен низкоскоростной механизм подачи, содержащий гидравлический цитиндр с гидрослед щим приводом, осушес1 . вл ющим перемещение штока, на котором закреплен катод-инструмент , и гидравлический цилиндр с гидрослед щим приводом , осуществл ющим перемещение штока , на котором установлена обрабатываема деталь IJ.A low-speed feed mechanism is known, which contains a hydraulic hydraulic drive with a hydro-next drive, a drying device. the movement of the rod, on which the cathode tool is fixed, and the hydraulic cylinder with a hydro-next drive, which moves the rod on which the workpiece IJ is mounted.

П.цравлический цилиндр, перемещающий катод-инструмент в направлении на обрабатываемую деталь, установлен на станине станка, а гидравлический цилиндр, перемещающий обрабатываемую деталь от катода-инструмента, установлен на столе станка.P. A hydraulic cylinder that moves the cathode tool in the direction of the workpiece is mounted on the machine bed, and a hydraulic cylinder that moves the workpiece from the cathode tool is installed on the machine table.

Перемещение штоков обоих гидр влических цилиндров подбираетс таким образом , что относительное перемещение катпда-инструмента к обрабатываемой детали составл ет минимально требуемые значени рабочей среды.The movement of the rods of both hydra cylinders is adjusted so that the relative movement of the cut tool to the workpiece constitutes the minimum required values for the working medium.

Недостатком такого низкосксфостного механизма катода-инструмента вл етс необходимость перемещени обрабатываемого издели и, как следствие этого , ограничение технологических возможностей оборудовани , в котором заложен указанный механизм. Так, например, невозможно осуществить обработку боковых О сков (утонений) на сферических поверхност х, обрабатываемых по мето- Я- электрохимического точени , а также обраболсу больших поверхностейThe disadvantage of such a low-rate mechanism for the cathode-tool is the need to move the workpiece and, as a result, the limitation of the technological capabilities of the equipment in which the mechanism is incorporated. So, for example, it is impossible to carry out the processing of side ocks (thinning) on spherical surfaces processed by the method of electrochemical turning, as well as processing large surfaces

Claims

The aim of the invention is to expand the range of processed items. design and simplification. This is compounded by hydrocy. The linzers of the cathode tool drives and the product are interconnected by a movable carriage. The invention is illustrated in the drawing. The mechanism contains a hydraulic cylinder 1, at one end of the rod 2 of which the hydraulic follower drive 3 is installed, and on the other - the cathode 4, the additional hydraulic cylinder 5 is fixed on the machine bed and has a self-hydraulic hydraulic follower drive 6. The hydraulic actuator rod 7 is connected to the movable carriage 8i on which is installed the first hydraulic cylinder. The mechanism works as follows. The cathode 4 is driven by hydraulic cylinders; the schra 1 is moved in the direction of the scientific research institute of the workpiece 9 by means of the following drive 3. The carriage 8 together with the first hydraulic cylinder moves in the opposite direction by the rod 7 of the additional hydraulic cylinder 5. The speed of the rod of the hydraulic cylinders it is selected in such a way that the actual movement of the cathode instrument relative to the workpiece is the minimum value of the working end. The proposed mechanism will provide accurate working feeds of a cathode instrument of 0.005-1.0 mm / min, since the resultant pickup is a ratio of two mutually opposite movements of hydraulic cylinder rods exceeding 1 mm / min, reliably carried out by the hydrosheeter. Placing the mechanism in the feed wire of the cathode tool will expand the range of machined parts and greatly simplify the design. equipment in which it will be used. Invention Formula The machine feed mechanism for electrochemical machining, including drives for moving the tool cathode and the machined part containing hydraulic cylinders, is distinguished by the fact that, in order to expand the range of workpieces and simplify the design, the hydraulic cylinders of both drives are interconnected by a moving carriage.
