Method for processing gas film holes with continuous rows of integral special electrodes

Abstract

The invention is suitable for the field of engine blade machining equipment, and particularly relates to a method for processing gas film holes with continuous rows of integral special electrodes, which comprises the following steps: adjusting a special electrode chuck according to the hole number, spacing and hole diameter of gas film holes of a blade; installing an electrode capable of machining the corresponding hole diameter on the electrode chuck; aligning the electrode chuck and a tooling, and determining the angle positions of the gas film holes; adjusting machining parameters, and machining a part gas film hole on an electric spark forming machine; multiple electrodes are distributed in an equal-interval row shape and used for machining a whole row of gas film holes; a plurality of limiting plates are arranged and are used for clamping the electrodes; the plurality of limiting plates detachably clamp the electrodes; the multiple electrodes distributed in the row shape at equal intervals are detachably clamped through the multiple limiting plates, and the gas film hole processing efficiency is improved; when the processing of the gas film holes interferes with the blade, an interference area can be avoided through the technology; and the gas film hole processing method is changed, and electric spark small hole machining is changed into electric spark forming machining.

Description

technical field [0001] The invention relates to the field of engine blade processing equipment, in particular to a method for processing gas film holes with a row of integral dedicated electrodes. Background technique [0002] Aircraft refers to a heavier-than-air aircraft that has one or more engines to generate forward thrust or pull, and the fixed wings of the fuselage to generate lift, and fly in the atmosphere. Aircraft can be divided into two categories: military aircraft and civilian aircraft. Military aircraft refers to aircraft used in various military fields, while civil aircraft generally refers to all non-military aircraft (such as passenger aircraft, cargo aircraft, agricultural aircraft, sports aircraft, ambulance aircraft, and experimental research aircraft, etc.). [0003] Different types of engines have different blade functions. The engine is roughly divided into piston and jet. The piston is relatively early, and its blades are mainly used to generate f...

Problems solved by technology

[0005] Among them, EDM gas film hole is the most mature and perfect technology, but the traditional EDM gas film hole is processed by a single hole on a multi-axis CNC high-speed EDM small hole machine, and small holes are processed on this equipment. The hole is processed step by step for a single hole, and the efficiency is not high; and when the multi-axis CNC high-speed small hole machining of the air film hole often encounters interference between the electrode used for the air film hole processing and other positions of the blade, thus increasing the processing difficulty
