Abstract

The invention belongs to the technical field of aircraft engine blade mortise repair, and particularly relates to a blade mortise adhesive tape repair device and method. The repair device comprises arepair block, and the repair block is provided with a first positioning surface for being attached to and positioned with an end face locking block of a mortise, a second positioning surface for beingattached to and positioned with the bottom surface of the mortise and a mold portion matched with an adhesive tape of a grading adhesive tape portion of the mortise for repairing the adhesive tape ofthe grading adhesive tape portion, and a separation space used for being separated from an adhesive tape of the bottom face non-repair portion of the mortise is arranged on the portion, close to thesecond positioning surface, of the mold portion. The mold portion can repair the gradient part of the adhesive tape in the gumming process of an aircraft engine blade, and the separation space used for being separated from the adhesive tape of the bottom face non-repair portion of the mortise is arranged on the portion, close to the second positioning surface, of the mold portion, so that the erroneous contact with the non-repair portion is avoided, and the repairing effect can be ensured.

Description

technical field [0001] The invention belongs to the technical field of aero-engine blade tenon repair, and in particular relates to a blade tenon rubber strip repair device and method. Background technique [0002] The current process uses tape cutting to make a mold, by sticking the tape on the tenon to ensure the position of the rubber strip, manually applying glue to the tape pasted on the tenon, and scraping the glue and tape with a blade to ensure the thickness of the glue strip . However, the existing technology cannot repair the part where the thickness of the rubber strip on the tenon is in a gradual shape. Contents of the invention [0003] In order to solve the problems existing in the prior art, the object of the present invention is to provide a blade tenon rubber strip repair device and method, which can repair the gradual change of the rubber strip during the process of applying glue to the tenon of the aero-engine blade. [0004] The purpose of the inventi...
