A kind of laser strengthening processing device

Abstract

The invention discloses a laser strengthening processing device, comprising a laser generator, an optical component, a first moving component, a second moving component, a third moving component and a sealing box. The first moving component is located outside the sealing box and can drive the optical component The reciprocating motion along the Z axis ensures the constant distance between the surfaces of different areas of the workpiece to be processed and the exit point of the laser beam after focusing. The third moving component is located in the sealed box, and the processing environment is suitable. The third moving component can drive the workpiece to be processed around. It rotates parallel to the axes of the X and Z axes, so as to realize the angle compensation of the workpiece to be processed, and then successfully complete the surface processing of the complex curved parts. The sealed box moves in the plane perpendicular to the Z axis, which ensures the smooth processing of different areas on the surface of the workpiece to be processed, and improves the laser beam intensified processing quality with higher output characteristics.

Description

technical field [0001] The invention relates to the technical field of laser strengthening processing equipment and its peripheral supporting facilities, in particular to a laser strengthening processing device. Background technique [0002] As a new type of surface property enhancement technology for parts, laser strengthening has been widely used in many fields, especially in the generation of surface strengthening layers of transition metal materials. Laser strengthening processes include laser shock strengthening, laser quenching, laser gas nitriding, and laser cladding. The principle is to use a focused laser beam with short pulse, high energy and high frequency output to generate a transient high temperature molten pool on the surface of the workpiece, so that the surface of the workpiece can be refined or combined with specific atmosphere control and special coating control to achieve surface alloying or Chemical metallurgy (such as the formation of nitride surface l...

Problems solved by technology

However, this method cannot meet the strengthening requirements of parts with complex surfaces. Nevertheless, the motion mode of the machine tool can still obtain higher process stability compared with the motion of the multi-axis manipulator, that is, the rigidity of the machine tool and the spatial motion accuracy are higher than those of the manipulator. more advantageous
