Embodiment 2

[0071] This embodiment discloses a working method of an air film hole processing device for an aero-engine blade: the method includes the following steps:

[0072] Step 1: Open the cover body, and fix the blade 16 of the aero-engine to be processed on the clamping head.

[0073] Step 2: Put the cover on the work box, input the blade material and the array program of the air film hole to be processed into the control system, and the central control system calls the laser processing parameters in the system library through the processing material, Generate the laser processing path through the array program; control the vertical drive mechanism to adjust the scanning galvanometer to a suitable position; control the servo motor and three-axis worktable to adjust the position of the blade to the position required for processing; control the manipulator to adjust the nozzle to a suitable position When the diaphragm pump works, inject acidic solution into the liquid storage area. Th...

Abstract

The invention relates to an aviation engine blade film hole processing device and a working method. The aviation engine blade film hole processing device comprises a working box, wherein a clamping mechanism is arranged in the working box and is used for clamping a workpiece; a cover body with an inner space communicating with an inner space of the working box is connected to the upper part of a workpiece box; a laser processing mechanism is connected to the top end of the cover body and can produce a laser ray so as to carry out laser processing on the workpiece in the working box; the coverbody is connected with a liquid feeding mechanism and an acid gas filtering mechanism; the liquid feeding mechanism can inject an acid solution to the workpiece in the workpiece box; the working box can collect the acid solution; and the acid gas filtering mechanism can filter acid steam produced in the filtering processing process. According to the processing device provided by the invention, a recasting layer can be effectively removed, and the film hole processing quality is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to an aeroengine blade air film hole processing device and working method. Background technique [0002] Aeroengine blades are usually made of nickel-based alloys, which can work at temperatures above 700°C and maintain their mechanical and physical properties, especially strength and corrosion resistance, for a long period of time. But these alloys are very difficult to machine due to low thermal conductivity, high toughness, strong work hardening, presence of highly wear-resistant carbide particles and strong tendency to form edges. [0003] Since the engine operates at such extreme temperatures, the blades must be cooled during operation. The blades can be cooled by air film holes. The purpose of the air film holes is to provide a flow of cooling gas that covers the profile of the blade and thus reduces its operating temperature. In order to obtain good...
