Description
(54) ЭЛЕКТРОД-ИНСТРУМЕНТ ДЛЯ РАЗМЕРНОЙ ЭЛЕКТРОХИМИЧЕСКОЙ ОБРАБОТКИ КРИВОЛИНЕЙНЫХ Изобретение относитс к размерной электрохимической обработке, в частности к обработке винтшых повфхностей переменного шага. Известны электроды-инструменты нежесткой конструкшш, примен емые при из готовлении внутренних поверхностей переменного сечени ц . Такие элекгроаы-инструменты ввиду нежесткой рабочей части, выполненной из упругого листового материала, принимают форму обрабатьюаемого канала, при этом nocTosfflCTBO межэлектрооных зазоров обеспечиваетс диэлектрическими вставками. Однако известные электроды-инструмен ты нежесткой конструкции имеют недостаточную цолговечность оиэлектрических вставок вследствие их износа и копирование пофешностей формы заготовок, и как следствие, низкую точность обработки. Цель изобретени - псжьппение точ- . ности при электрохимической обработке винтовьк поверхностей переменного ша- ПОВЕРХНОСТЕЙ га путем исключени вли ни погрешностей формы заготовки на форму электродаинструмента . Поставленна цель достигаетс тем, что в электроде-инструменте дл размерной электрохимической обработки, криволинейных поверхностей с рабочей частью из угфугого листового материала механиз-. мом ее деформировани , механизм деформировани выполнен в вице двух скреицсёаюшихс шарнирно закрепленных средней частью во фланце вала, на нижних концах которых закреплена рабоча часть в форме сектора. Причем :на указанном валу установлены две шестерни, одна из которых, закреплена жестко, а друга свободно, при этом последн имеет фланец с пазами, в которых размещены верхние концы стержней.

Known non-rigid construction electrodes are tools used to prepare the internal surfaces of a variable cross section. Due to the non-rigid working part made of an elastic sheet material, such electric tools take the form of a channel to be processed, while the nocTosfflCTBO interelectrocating gaps are provided with dielectric inserts. However, the known electrodes-instrumentation of a non-rigid structure have an insufficient coarseness of the dielectric inserts due to their wear and copying of the shapes of the blanks, and as a result, a low machining accuracy. The purpose of the invention is precision. during the electrochemical machining of screws of the alternating surface surfaces of ha by eliminating the influence of the shape errors of the workpiece on the shape of the electric tool. This goal is achieved by the fact that in an electrode electrode for dimensional electrochemical machining, curved surfaces with a working part made of carbon sheet material are mechanized. The method of its deformation, the deformation mechanism is made in the vice of the two cross-hinged hinged middle part in the shaft flange, at the lower ends of which the working part is fixed in the form of a sector. Moreover: two gears are installed on the shaft, one of which is rigidly fixed, and the other is free, while the latter has a flange with grooves in which the upper ends of the rods are placed. FIG. 1 shows the proposed Electro-nstrumen in FIG. 2 is a section A-A in FIG. I. Electrode-tool consists of a flexible closed plate 1, having the shape
