Problems solved by technology

[0004] The present invention aims to solve the problem that in the existing laser surface modification technology, due to the strong directionality of the laser, under the action of the traditional linear feed, the laser processing on the surface of the workpiece is not uniform, which will cause uneven hardening on the surface of the workpiece. To solve the technical problem of uniformity or tempering phenomenon, an ultrasonic-assisted laser surface modification device is provided. On the basis of ensuring the advantages of laser processing, it can improve the hardening degree of the workpiece surface, promote the uniformity of laser processing on the workpiece surface, and reduce the workpiece surface. roughness, ultimately increasing the service life of the workpiece

Abstract

The technical field of laser processing equipment of the present invention is specifically an ultrasonic-assisted laser surface modification device, which solves the technical problems in the background technology. It includes an ultrasonic vibration cutting device and a laser heating device, and the ultrasonic vibration cutting device includes a coaxial connected Horn and tool seat, also includes ultrasonic generator, non-contact electrical signal transmitter, processing tool and installation handle for connecting machine tool spindle; laser heating device includes laser generator, light guide cover, upper ring light guide mirror and lower ring light guide mirror. The present invention can realize real-time laser heating of the processed surface of the workpiece during the cutting process, and improve the processing efficiency while reducing the machinability of difficult-to-machine materials; the circumferential rotation of the upper annular light guide mirror can realize the circumferential light splitting of the laser, The axial reciprocating vibration of the lower annular light guide mirror can realize the axial splitting of the laser light, thereby realizing the control of the laser heating trajectory, and effectively reducing the occurrence of local overheating of the workpiece to be processed.

Description

technical field [0001] The invention belongs to the technical field of laser processing equipment, in particular to an ultrasonic-assisted laser surface modification device. Background technique [0002] Laser surface modification technology is a process in which high-energy and high-density lasers are applied to the surface of a workpiece, so that the surface material of the workpiece undergoes rapid heating and cooling, thereby changing the physical, chemical and mechanical properties of the surface material of the workpiece. Laser has the characteristics of strong directionality, stable wavelength, fixed phase and high power density. A reasonable laser can produce thermal effects, photochemical effects, pressure effects and electromagnetic field effects on the surface of the workpiece, and produce a surface strengthening layer with fine grains and a variety of metastable phases and intermetallic compounds, thereby improving the wear resistance, corrosion resistance, and c...
