Laser remanufacturing of thin-walled thin-walled blade-like multifunctional fixtures

Abstract

The invention discloses a laser remanufacturing multifunctional tooling fixture for thin-walled parts with irregularly curved surfaces such as blades, and relates to the field of laser remanufacturing tooling fixtures. It includes a base, a mechanical clamping mechanism, a positioner, a three-jaw chuck and a pressing device. There is an air storage tank along the transverse direction in the base; a through-hole array is distributed between the air storage tank and the upper surface of the base. ;The upper surface of the base is provided with a through-type T-shaped guide groove along the transverse direction; a slider is provided in the guide groove; the slider is connected with the pressing device; a positioner with two degrees of freedom is installed on the base; A positioner control box matching with the positioner is installed in front of the positioner; a three-jaw chuck is installed on the positioner; mechanical clamping mechanisms are installed at the left and right ends of the base. The invention realizes high-precision forming shape and deformation control, and simultaneously has a good defect elimination effect.

Description

technical field [0001] The invention relates to the field of laser remanufacturing tooling fixtures, in particular to a laser remanufacturing multifunctional tooling fixture for thin-walled parts with irregular curved surfaces such as blades. Background technique [0002] Due to the characteristics of thin wall, complex profile structure and high material value, thin-walled parts such as blades have high manufacturing value and product added value, but they are subject to high-speed particle erosion and high-temperature flue gas corrosion in service conditions. As well as the cavitation effect of air bubbles, it is easy to cause volume damage and cause the entire unit or equipment to stop. Therefore, laser remanufacturing of such components has positive economic, environmental and social effects. However, the volume damage location and degree of this type of parts present the characteristics of nonlinearity, discretization, and multi-scale. In addition, the profile structur...

AI Technical Summary

Problems solved by technology

However, the volume damage location and degree of this type of parts present the characteristics of nonlinearity, discretization, and multi-scale. In addition, the profile structure is complex, shape fitting and deformation control are difficult, and it is easy to cause tip and edge collapse, forming layer pores, and Forming hot cracks and other remanufacturing defects

However, the laser remanufacturing of such parts lacks corresponding special fixtures to achieve high-precision forming shape and deformation control and special fixtures with good defect elimination effects
