Abstract

The invention provides a turbine engine blade automatic repairing device and method. The turbine engine blade automatic repairing device comprises a computer, a laser, a mechanical arm, a powder feeder, a laser head, a three-dimensional scanner, a blade defect automatic detection device, a polishing device and an installation base. According to the turbine engine blade automatic repairing method, the computer generates a laser repairing movement path, laser generated from the laser is projected to turbine engine blades with repairing material powder, the mechanical arm drives the installation base to move with six degrees of freedom inside space, and the laser performs fusion covering on the turbine engine blades along a set path. The turbine engine blade automatic repairing device and method adopts highly integrated and automated repairing device and technology to achieve automatic and intelligent repairing of the turbine engine blades and accordingly the repairing efficiency and quality of the turbine engine blades are improved.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a turbine engine blade automatic repair equipment and a repair method thereof. Background technique [0002] The high-pressure turbine blades of gas turbines and aero-engines are one of the key components of the entire engine. They are directly driven by the high-pressure and high-temperature gas after combustion, and generate aerodynamic power through high-speed rotation. These high-performance blades need to operate for a long time under high-temperature and high-stress load conditions, and their life is often the weak link that determines the life of the entire engine life cycle. Therefore, it is necessary to use advanced detection and repair technology to automatically repair these defective and damaged blades, so that they can meet the requirements of industrial equipment, prolong their service life, and obtain considerable technical and economic benefits. Due to the harsh w...
