Abstract

The invention belongs to the technical field of surface modification, and particularly relates to a device and method for laser processing of the surface of a curved workpiece. The device comprises a workpiece movement workbench, a marking support, a laser marking device, a rotating table, a first bearing pedestal, a first transmission rod, a worm, a scale shaft, a plurality of studs vertically arranged on the rotating table, a lifting table, a second bearing pedestal, a second transmission rod, a worm wheel, a gear motor and a three-clamping-claw disc selectively installed at an end of the second transmission rod or an end of the first transmission rod through a connecting sleeve. The workpiece is clamped by the three-clamping-claw disc. The laser marking device is located over the workpiece. According to the device and method, through an electric mode, the laser marking device is commanded to conduct fixed-point marking to carry out circumferential etching on the peripheral face of the curved workpiece; and through a manual mode, the laser marking device is commanded to carry out etching along the axis of the curved workpiece, etching of axial lines along the axis of the workpiece is achieved, and a circumferential groove-shaped microstructure and an axial groove-shaped microstructure can be accurately processed on the peripheral face of the curved workpiece.

Description

Technical field[0001]The present invention belongs to the field of surface modification, and more particularly to devices and methods of laser processing curved surface workpiece.Background technique[0002]Friction and wear performance is an important nature of the surface of the metal workpiece. It is shown that the microstructure is machined on the surface of the metal workpiece, which can effectively improve the resistance reduction resistance on the surface of the metal workpiece. These surface microstructures can improve the resistance to resistance to the surface of the metal workpiece, improve the self-cleaning performance of the surface of the workpiece, and can also be used to enhance the corrosion resistance of the surface of the workpiece. In addition to using chemical etching, micro-texture is prepared on the surface of the metalwork, and the current laser etching method is also a good choice. With the development of short wavelengths and short pulse lasers, laser etching...
