Abstract

The invention discloses a laser drilling device assisted by laser-induced impact waves. The laser drilling device comprises four modules, namely, a workpiece clamping device, a laser drilling device, a device capable of allowing a laser to induce the impact waves and a control system device, wherein the laser drilling device and the device capable of allowing the laser to induce the impact waves are arranged on the workpiece clamping device from top to bottom, and the control system device is connected with the laser drilling device and the device capable of allowing the laser to induce the impact waves through cables. According to the laser drilling device assisted by the laser-induced impact waves, the depth limit of laser drilling can be improved, the thickness of a recast layer can be lowered, the micro-crack producing rate can be lowered, the laser drilling efficiency can be improved, and the laser drilling device can be applied to laser drilling of medium plates and thick plates.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a device that utilizes laser-induced shock waves to assist laser drilling. technical background [0002] Laser drilling technology is one of the earliest application technologies of laser in the field of material processing. During the laser drilling process, the high-energy pulsed laser is focused on the surface of the workpiece to heat, melt or even vaporize the material, and then the molten material is extruded out of the hole under the joint action of the recoil pressure of the rapid expansion of the metal vapor and the pressure of the high-pressure auxiliary gas. , the subsequent pulsed laser continues the above process, and the material is continuously removed until a blind hole or a through hole is formed. [0003] Compared with other drilling methods, laser drilling has significant advantages such as large hole depth-to-diameter ratio, no contact, no tool loss,...
