Abstract
The present invention relates to a laser application technique. The present invention is characterized in that a safe and pollution-free impact head for laser impact strengthening is used; a constraint glass plate which plays the role of constraints and a converging lens are arranged at both sides inside the same cylinder and are respectively fixed by a front cover and a back cover; the external surface of the constraint glass plate is coated with a light energy absorption coating layer; the middle of the front cover which contacts the light energy absorption coating layer is provided with a metallic or nonmetallic thin layer so as to transmit impact waves. When the light energy absorption coating layer generates plasma body explosive impact waves, broken glass pieces remain in the cylinder, which is favorable to personnel safety and environment protection; therefore, the entire laser impact device can be directly used in production fields.
Description
Technical field
The present invention relates to laser application technique.
Background technology
It is the laser processing technology that a kind of new development is got up that laser-impact is handled (LSP).Its principle of work is to utilize high power laser light irradiation to metal works or material surface, produces high-intensity shock stress ripple, makes workpiece surface generation viscous deformation, thereby improves its anti-fatigue performance, increases the service life.The laser beam that sends from the high power laser light generating unit in the prior art all needs through positive lens usually, and then irradiation is to the workpiece surface place that scribbles the luminous energy absorber coatings.Positive lens is a single-piece, need be installed in the appropriate location again by the frame aiding support during use.Therefore at present not only overall volume is huge to be used for device of high power laser that LSP handles both at home and abroad, and debugging operations is very difficult, and it is very inconvenient to use.In actually operating, when producing high-intensity shock stress ripple, the sheet glass that plays effect of contraction can be broken through and be splashed everywhere, influences operator safety on the scene, also polluted relevant to field device, and influence environment neatly.In addition, on workpiece surface, be coated with the luminous energy absorber coatings, not only time-consuming, also can have influence on workpiece around the position.
Summary of the invention
The objective of the invention is to,, provide a kind of can the realization will assemble lens and scribble the luminous energy absorber coatings and the incorporate laser treatment impact head of sheet glass of an effect of contraction at deficiency of the prior art.
Purpose of the present invention is realized by following mode.
The impact head that is used for the laser-impact processing of the present invention, it is characterized in that, the sheet glass and the positive lens that play effect of contraction are installed in the intravital two ends of same tube, and fix by forward and backward lid respectively, the constraint sheet glass on the surface of protecgulum inner face, scribble the luminous energy absorber coatings, be metal or nonmetallic thin layer in the middle part of the protecgulum that contact with the luminous energy absorber coatings; Also can in the cylindrical shell between positive lens and the constraint sheet glass, be provided with a glass baffle plate.Described is evenly to smear and form by absorbing laser energy and rapid ionized coating at the luminous energy absorber coatings of constraint on the sheet glass, for example, and other tailor-(made) coating that uses in black paint in the coating market or the existing laser treatment technique etc.
The impact head that is used for the laser-impact processing of the present invention, safety non-pollution on the outer surface of its luminous energy absorber coatings attached to the constraint sheet glass, has changed the way that in the prior art luminous energy absorber coatings directly is coated in workpiece surface.Not only help operation; and when producing the plasma body explosion wave behind the coating absorption laser; broken sheet glass is stayed in the cylindrical shell; can not produce glass slag splash phenomena everywhere; help personnel safety and environment protection, thereby the laser impact processor of integral body directly can be placed the production scene to use.
Laser-impact head of the present invention, can with the supporting use of specially designed high power laser light generating unit, also can be used in the laser strengthening and processing device of prior art.
Description of drawings
Be further described below by embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of laser-impact head of the present invention.
Embodiment
Referring to Fig. 1,2 is positive lens.1 is the fixing bonnet of positive lens, its periphery be provided with the cylindrical shell inner hole wall on threads engaged, it will be assembled in the rear end endoporus that lens 2 are fixedly mounted on cylindrical shell 3.4 is the glass baffle plate, and this baffle plate glass fragment that forms that can prevent to explode flies to the positive lens place, and is convenient to cleaning.5 is interior cover, and it is used for fixing glass baffle plate 4.6 are the constraint sheet glass.The other end of cover 5 in it is arranged on, and have protecgulum 8 fixing.On the surface of protecgulum inner face, scribble luminous energy absorber coatings 7 at this constraint sheet glass.The middle portion of protecgulum is a thin layer, shockwave can be delivered on the workpiece surface.At first enter positive lens 2 from the laser beam of combined live movable joint beam Propagation device output, again by glass baffle plate 4 and constraint sheet glass 6, be mapped to luminous energy absorber coatings 7 places, high-power laser makes the rapid ionization of this partial coating, produce plasma body and blast formation shockwave, the impact workpiece surface is finished and is strengthened function.Because stopping of protecgulum, the constraint sheet glass disintegrating slag that is exploded is brokenly stayed in the cylindrical shell, can not splash everywhere.The described luminous energy absorber coatings that adheres on the constraint sheet glass is that pitch-dark evenly the smearing of buying on the market forms, and the thickness of coating is about 50 microns.
Claims (2)
1. one kind is used for the impact head that laser-impact is handled, it is characterized in that, the constraint sheet glass and the positive lens that play effect of contraction are installed in the intravital two ends of same tube, and fix by forward and backward lid respectively, the constraint sheet glass on the surface of protecgulum inner face, scribble the luminous energy absorber coatings, be metal or nonmetallic thin layer in the middle part of the protecgulum that contact with the luminous energy absorber coatings; Described is evenly to smear and form by absorbing laser energy and rapid ionized coating at the luminous energy absorber coatings of constraint on the sheet glass.
2. the impact head that is used for the laser-impact processing as claimed in claim 1 is characterized in that being provided with a glass baffle plate in the cylindrical shell between described positive lens and constraint sheet glass.
