A laser shock device that can automatically replace the glass constrained layer

Abstract

Belonging to the field of laser shock peening, the invention in particular relates to a laser shock device capable of replacing a glass restraint layer automatically. The device comprises: a laser, afocusing lens, a light guide tube, a standby glass bin, a stepping motor, a replacement rack, a special restraint layer, a glass sheet baffle, a rubber cushion, a workpiece, an absorption layer, a waste sheet bin, a fine-tuning knob, a fine-tuning gear and a fine-tuning rack. The special restraint layer is loaded into the standby glass bin, then the stepping motor drives the replacement rack to realize replacement of a shock layer. The light guide tube can drive the pinion and rack mechanisms to realize movement by adjusting the fine-tuning knob, thus adjusting the relative position of the restraint layer and the absorption layer. After a certain number of shocks are carried out on the glass restraint layer, a computer controls the stepping motor in terms of driving the replacement rack toreplace the restraint layer, and at the same time the discarded glass sheet is pushed into the waste sheet bin. The laser shock device provided by the invention can effectively solve the problems offrangibility, troublesome replacement and high use cost of glass restraint layer, and effectively improves the working efficiency and effect of laser shock processing.

Description

technical field [0001] The invention belongs to the field of laser shock strengthening, in particular to a laser shock device capable of automatically replacing a glass constraining layer. Background technique [0002] Laser shock peening technology is to use high-energy-density short-pulse laser to shock the absorbing layer of the surface of the material, make it plasma and generate an explosion, and a strong shock wave acts on the surface of the material and propagates to the inside, causing plastic deformation and deformation in a certain area of ​​the surface of the material. The complex dislocation structure forms a certain thickness of residual compressive stress layer, which improves the fatigue strength and corrosion resistance of parts. At present, this technology is widely used in machinery manufacturing, aerospace, microelectronics, national defense, medical treatment and many other fields. [0003] In the process of short-pulse laser shock strengthening, in orde...
