Refering to Fig. 1, Fig. 1 is the flow for the method for making deep trouth on aluminium alloy using laser that the embodiment of the present invention one provides Figure, the method for making deep trouth on aluminium alloy using laser that embodiment of the present invention provides, including：
11：First depth value is got by the thickness for measuring assembling thing；
The deep trouth carved in the embodiment of the present invention is in order to inlay assembling thing, so the depth of deep trouth will be able to will assemble In thing is embedded in, first depth value is exactly the thickness for assembling the thickness of thing or being slightly less than assembling thing, for example, it is desired in aluminium Some logo is inlayed on alloy, then needs first to measure this logo thickness, this logo can be accommodated further according to this thickness engraving Deep trouth, the depth of deep trouth can be slightly less than this logo thickness, and such logo can protrude from deep trouth so more after inlaying Add attractive in appearance, it is necessary to which explanation, first depth value is depth of the aluminum alloy surface to deep trouth bottommost.
12：The first laser Shu Jinhang waist beams of laser transmitting are expanded to form second laser beam, then by described second Laser beam is focused, and the second laser beam hot spot after focusing is less than the hot spot and depth of focus length of the first laser beam Depth of focus length of the degree more than the first laser beam；
In embodiments of the present invention, the focus lamp of use is the focus lamp of 254 camera lenses, after this focus lamp can make focusing Laser depth of focus is grown, and can make the side wall of deep trouth and the angle of aluminum alloy surface compared with angle caused by other focus lamps during depth engraving Spend it is small, because hot spot caused by this camera lens is larger, because the characteristic of focus lamp is focal beam spot diameter and launching spot diameter It is inversely proportional, so being coordinated therewith using beam expanding lens, is enlarged light beam using beam expanding lens, focus lamp can just make light beam Hot spot focus on very little, the energy density of such hot spot will be very big.
13：On the aluminium alloy laser engraving depth be first depth value deep trouth, wherein, the deep trouth be to Few two secondary clearings engraving forms；
14：Laser reconditioning all is carried out to the side wall of the deep trouth after each engraving, so that the deep trouth side wall and institute Stating the angle of aluminum alloy surface tends to right angle；
It is not that disposably deep trouth is carved to complete using laser engraving deep trouth, and is divided into repeatedly being carved, and It is every side wall carved and once repair a deep trouth, for example, the depth that the depth value of half first can be first carried out to deep trouth is entered Row engraving, then carry out repairing deep trouth side wall, the depth for then carrying out the remaining depth value of half first is carved, then is carried out Repair deep trouth side wall；Or the first depth value can also be divided into and deep trouth being carved three times, and often carve once to deep trouth Side wall finishing once.
Since it is desired that the deep trouth of engraving is not one but multiple, in this case, aluminium alloy can be preferably controlled The uniformity of depth between upper groove and groove, because aluminum alloy materials are heated effects, if directly carved deep trouth complete Depth, aluminum alloy materials are in heating status, and the temperature rise of aluminum alloy materials can also change to the absorptivity of laser, this When carve second deep trouth again, deep trouth is inevitable inconsistent with the depth of deep trouth before.And a groove is divided into repeatedly This mode of engraving can avoid heat from excessively concentrating with rapid dispersion energy, allow aluminium alloy not reached energy suction by thermal balance Receive balanced.
Because the side wall of the deep trouth using laser engraving and the angle of aluminum alloy surface are larger, it is complete so thing can not will to be assembled Whole is mounted in deep trouth, so also needing to repair the side wall of deep trouth, it is generally the case that in deep trouth side wall and aluminium alloy The angle on surface can make assembling thing realize that perfection is bonded with deep trouth, reach and most preferably inlay when between 90 degree to 98 degree.In reality Apply in example, to the finishing of deep trouth side wall nor disposable finishing is complete, and is divided into repeatedly repairing, so when carrying out repairing side wall The laser of very strong energy is not needed, so repairing side wall would not cause corner burr very serious, while so place of deburring Residual miscellaneous accumulation is not had, and shading can be more smooth, while improves operating efficiency；It is if disposable after deep trouth has all been carved Side wall is repaired, because the deep trouth side wall for needing to repair is more, it is necessary to which the stronger laser of energy, laser energy is too strong to cause side There is very deep very serious burr in angle, so carries out the depth and the first depth value deviation that can make deep trouth during deburring to shading again It is larger, cause deep trouth engraving failure.
In embodiments of the present invention, by by laser beam be enlarged waist beam handle, then by the laser beam focus into Depth of focus grows and the small laser of hot spot, hot spot I increase laser beam energy density, while to more secondary clearings in aluminum alloy surface Engraving forms a complete deep trouth, all carries out deep trouth side wall finishing after each engraving, makes deep trouth side wall and aluminum alloy surface Angle tend to right angle, this angle can be very good assembling thing being mounted in deep trouth, and the method for this engraving deep trouth is than existing Some engraving processes substantially increase speed and efficiency.
