Description

Известно устройство дл  обработки сопр жений пересекающихс  поверхностей, преимущественно прикомлевых участков лопаток газотурбинных двигателей, содержащее вращающийс  контактный ролик, огибаемый абразивной лентой. Предлагаемое устройство отличаетс  от известных тем, что контактный ролик выполнен в виде сопр женного с пустотелым валом профильного кольца, огибаемого узкой абразивной лентой вдоль оси его вращени . Такое выполнение устройства позвол ет повысить точность обработки и стойкость абразивной ленты. На фиг. 1 схематически изображено предлагаемое устройство; на фиг. 2 - вид по стрелке А на фиг. 1. Устройство состоит из контактного ролика 1, который с помощью привода 2 вращаетс  в корпусе щниндел  5. В сочленении пустотелого вала 4 с контактным роликом 1 имеютс  отверсти  5 дл  подачи внутрь вала 4 узкой абразивной ленты 6. Дл  направлени  движени  ленты 6 в головке ролика / установлена втулка 7, на которой размещены опорные ролики 8. Обрабатываема  деталь 9 закреплена в приспособлении 10, подаваемом на врезание механизмом подачи. Устройство работает следующим образом. Контактный ролик приводитс  во вращение от привода 2, при этом обрабатываетс  радиус сопр жени  R и поверхность Б детали 9. По мере съема припуска деталь подаетс  на врезание по стрелке В. Дл  обработки профильных поверхностей обрабатываемой детали сообщают соответствующее движение обкатки, например, при помощи копировальных устройств. По мере износа участков ленты 6 в зоне резани  ее периодически или непрерывно перематывают вдоль оси вращени  ролика 1 по стрелке Г. На одном ролике может быть размещено несколько лент. Предмет изобретени  Устройство дл  обработки сопр жений пересекающихс  поверхностей, преимущественно прикомлевых участков лопаток газотурбинных двигателей, содержащее вращающийс  контактный ролик, огибаемый абразивной лентой , отличающеес  тем, что, с целью повыщени  точности обработки и стойкости абразивной ленты, контактный ролик выполнен в виде сопр женного с пустотелым валом профильного кольца, огибаемого узкой абразивной лентой вдоль оси его вращени .A device for treating mates of intersecting surfaces, preferably near priklevyh areas of blades of gas turbine engines, contains a rotating contact roller which bends around an abrasive belt. The proposed device differs from the known ones in that the contact roller is made in the form of a profile ring mated with a hollow shaft, which bends around the narrow abrasive tape along its axis of rotation. Such an embodiment of the device improves the processing accuracy and durability of the abrasive belt. FIG. 1 schematically shows the proposed device; in fig. 2 is a view along arrow A in FIG. 1. The device consists of a contact roller 1, which by means of the drive 2 rotates in the housing of the shndel 5. In the articulation of the hollow shaft 4 with the contact roller 1 there are holes 5 for feeding the narrow abrasive belt 6 inside the shaft 4 to guide the movement of the tape 6 in the roller head / mounted sleeve 7, on which the support rollers 8 are placed. The workpiece 9 is fixed in the tool 10, which is fed to the plunge by the feed mechanism. The device works as follows. The contact roller is driven from the drive 2, and the mating radius R and the surface B of the part 9 are machined. As the stock is removed, the part is fed into the plunging along arrow B. For machining the profiled surfaces of the workpiece, a corresponding running run is reported, for example, by using copiers devices. As parts of the tape 6 are worn in the cutting zone, it is periodically or continuously rewound along the axis of rotation of roller 1 along arrow G. Several tapes can be placed on one roller. The subject of the invention is a device for processing mates of intersecting surfaces, preferably near the crinkle sections of gas turbine engine blades, containing a rotating contact roller around the abrasive belt, characterized in that, in order to improve the processing accuracy and durability of the abrasive belt, the contact roller is made in the form of an interface with a hollow shaft of the profile ring, which bends around the narrow abrasive tape along the axis of its rotation.
