Problems solved by technology

[0003] However, at present, the processing of air film holes generally adopts electric spark drilling. When using electrode wire to drill holes, the positioning of the electrode wire, that is, the position of the air film hole on the blade, depends on the naked eye. This manual positioning method, the electrode wire The positioning accuracy is low, the hole position error of the air film hole is large, the production efficiency is low, the cooling effect of the turbine blade is affected, and the service life of the turbine engine is reduced

Abstract

The invention discloses an air film hole positioning tool, and the air film hole positioning tool is used for electrosparking air film holes of turbine blades and comprises a positioning part used forclamping blade bodies of the turbine blades, and guide holes used for an electrode wire to penetrate through are formed in the positioning part in a penetrating manner. According to the air film holepositioning tool, the position precision of the air film holes can be improved, the hole position errors of the air film holes are reduced, the production efficiency is improved, and the cooling effect of turbine blades is improved.

Description

technical field [0001] The invention relates to the technical field of turbine blade processing, in particular to a gas film hole positioning tool and a processing method thereof, and a gas film hole processing and detection method. Background technique [0002] Turbine blades are an important component of the turbine section in a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure air into the burner to maintain the engine's work. Turbine blades generally bear greater working stress and higher working temperature, and the changes of stress and temperature are frequent and severe. Moreover, in order to improve turbine efficiency, the surface shape of turbine blades is usually designed as a twisted variable-section surface. complex. In order to cool the turbine blades and prolong the service life of the turbine blades, air film holes are arranged in the turbine blades. [0003] However, at present, the processin...
