Property.
Detailed description of the invention
The present invention is further described with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of apparatus of the present invention.
Specific embodiment
The focus lamp 3 of laser impact intensified fixed optical path 2 as shown in Figure 1 prevents damaging device, including 2 He of fixed optical path
Focus lamp 3 in fixed optical path 2 is set.Fixed optical path 2 is inputted as laser, and outlet is connected to the light inlet of protection cylinder 5,
Protect cylinder 5 that there is the light-emitting window towards fixed tube outlet end, laser is input to entering for protection cylinder 5 from fixed optical path 2 along straight line
Optical port exports later from light-emitting window, to 10 shock peening of part.
In embodiment, protecting inner space of the cylinder 5 between light-emitting window and entrance light to connect outward has compressed gas supply
Device.Compressed gas feedway is lasting to compressed gas is fed inside protection cylinder 5, these compressed gas are towards light-emitting window
Direction is protected by certain flow rate and forms certain air pressure in cylinder 5, then, in laser-impact as shown in Figure 1
In the process, the painting water layer 9 of part 10 is because impact is formed by the droplet of splashing and coating vapour i.e. will not be towards 3 side of focus lamp
To movement, impact injury will not be caused to focus lamp 3 or be adhered on focus lamp.
In embodiment, protection cylinder 5 is in the circular cone shape that light inlet is big, light-emitting window is small.Space of the compressed gas from large aperture
When to small-bore spatial flow, the pressure of protection 5 inside corresponding position of cylinder can be gradually increased, and gas flow rate can also be corresponded to and be mentioned
Height guarantees the suitable pressure of light-emitting window position.In addition, the protection cylinder of this circular cone shape is less than light inlet due to light-emitting window bore
Bore, for preventing laser reflection to focus lamp from also functioning to the effect of protection.The bore of light-emitting window is selected according to lasing beam diameter
It takes, generally takes 8~15mm.
It is further preferred that forming air pressure in protection cylinder 5 is 1.5~2 times big due to the gas supply of compressed gas feedway
The pressure of air pressure can either avoid damage to focus lamp 3 under the value range, will not influence the stability for applying water layer 9.
The infeed of compressed gas can be accomplished by the following way:
Side opening is opened up in the side wall of protection cylinder 5, which is inclined hole, at a certain angle with protection 5 inner wall shape of cylinder；It is described
Compressed gas feedway include compressor 7 and communicating pipe 6, the outlet of 6 connect compressor 7 of communicating pipe and side opening, communicating pipe 6
Preferably hose.
It is further preferred that being additionally provided with plane mirror 4 on fixed optical path 2, the direction which is covered on focus lamp 3 is solid
On the surface for determining 2 outlet end of optical path.The plane mirror 4 equally plays the role of physical protection for focus lamp 3, is equivalent to be formed
One of Physical barriers.4 surface of plane mirror is coated with anti-reflection film, and 1.053 μm~1.06 μm of wavelength, anti-reflection rate 99%.
Focus lamp 3 is damaged after laser reflection in order to prevent, embodiment adjust automatically laser in the following ways
Incident angle.
It is provided with range sensor 8 at the light-emitting window of the protection cylinder, fixed optical path 2 adjusts structure equipped with incidence angle,
Range sensor 8 is connect with incidence angle adjustment architecture signals.Incidence angle adjustment structure can be mechanical arm or control system 1,
Its output angle (incident angle α) that fixed optical path 2 can be adjusted by way of automatic control.
As shown in fig. 1, the center of protection 5 light-emitting window of cylinder is arranged in range sensor 8, is used for real-time detection and goes out
Optical port center applies the distance h of water layer 9 to part 10 to be fortified, then feeds back the meter that control system 11 carries out laser incident angle α
It calculates and chooses, adjust.
Specifically, laser incident angle α and the minimum incident angle α for preventing reflected light damage focus lamp 3minRelationship Wei α≤
αmin,Wherein R is the aperture of light-emitting window.
In embodiment, passes through 8 detection data of range sensor and feed back to control system 1, real-time update laser minimum enters
Firing angle degree, to guarantee that part 10 at different positions, can require control laser action in part according to minimum incidence angle
Incident angle on 10 prevents laser reflection light from causing to damage to focus lamp 3, avoids artificial adjustment laser incident angle and brings
Inconvenience and accuracy it is poor the problems such as, improve the security performance of focus lamp 3.
The above is the preferred embodiment of the present invention, is not constituted a limitation on the scope of protection of the present invention.
