Description

Если пересекающиес  поверхности обрабатываемой детали имеют сложный криволинейный профиль, который не облегает широка  абразивна  лента, то примен етс  узка  абразивна  лента. Дл  сообщени  узкой ленте полеречных перемещений примен ютс  предназначенные дл  этой цели механизмы. На чертеже в качестве примера такого .механизма изображено устройство, содержащее направл ющие ролики 3- и 4, установленные на кронщтейне 11, закрепленном на валу 12, который совершает качательные движени  вокруг своей оси 00. Ролик 10 в этом случае целесообразно устанавливать на кронштейне 11, например , с помощью рычага 13.If the intersecting surfaces of the workpiece have a complex curved profile that does not fit a wide abrasive belt, then a narrow abrasive belt is used. Mechanisms designed for this purpose are used to communicate narrow belt movements. In the drawing, as an example of such a mechanism, there is shown a device comprising guide rollers 3- and 4 mounted on a brace 11 mounted on a shaft 12 that oscillates around its axis 00. In this case, the roller 10 can be mounted on a bracket 11, for example, using a lever 13.

Дл  восстаиовлени  или доводки контактного копира 5 абразивную ленту 1 устанавливают абразивным покрытием к его рабочим поверхност м, привод т во вращение щкивом 2 и сообщают поперечные перемещени  качанием вала 12, несущего ролики 3 и 4. Поджим участков 8 и 9 эталонного копира « контактному копиру 5 осуществл ют с помощью рычага подачи 6 или перемещением самого копира 5. Конец обработки контактного копира определ ют, например, по полному сн тию черноты на протравленных кислотой его изношенных рабочих поверхност х.To restore or refine the contact copier 5, the abrasive tape 1 is installed with an abrasive coating to its working surfaces, rotated with the tongue 2, and transverse movements are reported by swinging the shaft 12 carrying the rollers 3 and 4. Pressing sections 8 and 9 of the reference copier to contact copier 5 carried out using the feed lever 6 or by moving the copier 5 itself. The end processing of the contact copier is determined, for example, by completely removing the black on its worn-out working surfaces etched with acid.

Предмет изобретени Subject invention

Устройство дл  восстановлени  шлифованием абразивной лентой из1нощенных контактных копиров, используемых преимущественно при обработке прикомлевых участков лопаток ГТД, имеющих радиусные сопр жени  нересекающлхс  поверхностей, вынолненное в виде лентопрот жного механизма и эталонного копира, рабоча  поверхность которого эквидистантна на толщину ленты поверхности контактного копира, отличающеес  тем, что, с целью повышени  точности обработки , эталонный копир выполнен со щельюA device for restoring abrasive tape with grinding from worn contact copiers, which are used mainly in the processing of priklyulevy areas of GTE blades, which have radius matings of non-cutting surfaces, made in the form of a tape mechanism and a reference copier, the working surface of which is equidistant to the thickness of the contact copier surface, not the same that, in order to improve the accuracy of processing, the reference copier is made with a slit

в месте радиусного сопр жени  пересекающихс  поверхностей, через которую пропущена ветвь ленты, огибающа  расположенный за щелью ролик лентопрот жного механизма.in the place of the radius junction of intersecting surfaces, through which the tape branch is passed, the tape roller mechanism located around the slot.
