Laser-light beam melts, form the small cladding layer of complex function structure, low dilution rate, a welding deformation, and by quick heating and
The cladding process of cooling is readily available high-quality and wear-resisting cladding layer.Laser cutting technique is using high power density laser Shu Zhao
Cut material is penetrated, material is heated to vapourizing temperature quickly, evaporation forms hole, the movement with light beam to material, hole
Hole is formed continuously (such as 0.1mm or so) joint-cutting of narrower in width, the technology cut to material.Laser melting coating and laser cutting
The features such as technology all has small work piece thermal deformation, high working efficiency, but shortcomings are there is also in process, such as swash
Light reflects, and dust splashes etc..
The metallic dust splash in laser melting coating or laser cutting process is easily adhered on laser head protection eyeglass, day
The product moon is tired, it is necessary to change protection eyeglass, if changed not in time, in some instances it may even be possible to the serious consequence such as cause laser head to burn out, so
One both influences operating efficiency and quality, also increases cost input.In current production work, the solution to this problem
Method is mostly the installation copper coin at the segment distance of laser head lower end one, and installing simple gas nozzle in laser head side is used to remove
The dust of splashing, but these methods go the elimination effect of chalk dust removing general, and the installation of copper coin is also largely by processing workpiece dress
The influence of position is pressed from both sides, cannot even be installed sometimes.
The content of the invention
It is an object of the invention to provide a kind of simple structure, easy to process, safe and effective, raising cladding and cutting process
Work quality and efficiency, the laser head lens protecting device for being capable of reduces cost.
The present invention includes protective gas nozzle, protection baffle plate, protective gas pipeline and connector, wherein protective gas nozzle
It is the pipe with elbow, baffle plate mounting groove, the mounting groove is provided with the tube wall side midline position of protective gas nozzle straight tube
Cross sectional shape is T-shaped, and one end cross sectional shape of baffle plate is T-shaped with what mounting groove agreed with, and baffle plate is fixed on protection by mounting groove
On gas nozzle and parallel to nozzle-axis；A row amount phase is respectively equipped with the upper and lower protective gas nozzle tube wall of mounting groove
Deng the fumarole of, positional symmetry；Light hole is provided with above-mentioned baffle center, is provided with for the lower surface by laser beam, baffle plate
One layer of two-sided colloid, from 3M7812 types white double faced adhesive tape, material is Kapton film silica gel to the colloid, with high temperature resistant corrosion resistant
The characteristic of erosion, colloid center is provided with big light hole first-class with baffle plate；One end of protective gas nozzle is blind end, its other end
It is connected with extraneous protective gas appendix, connector is located on protective gas pipeline, for the connection of single unit system and laser head,
Ensure that above-mentioned baffle plate is parallel with laser head eyeglass during installation.
The present invention has the following advantages that compared with prior art：
1st, protective gas nozzle and baffle plate are integrated, good appearance is compact, by working environment, work piece clamping
The influence of the extraneous factors such as position is smaller.
2nd, nozzle and baffle plate are connected by groove, can realize that baffle plate mounts and dismounts summary, are improved and are changed baffle plate just
Prompt degree.
3rd, the upper and lower both sides of protective gas nozzle mounting groove are designed with that quantity is equal, and the fumarole of positional symmetry can make gear
Plate reaches upper and lower surface air pressure balance at work, and uniform force also can more efficiently stop the dust pollution eyeglass of splashing.
4th, baffle plate lower surface is stained with one layer of solid colloid, can with more efficient stop and absorb splashing metallic dust and
Reflected light, effectively protects laser head.
5th, baffle plate is conveniently replaceable, with low cost, drastically reduce the area the maintenance cost of laser head.

Specific embodiment
In the laser head lens protecting device schematic diagram shown in Fig. 1-Fig. 3, protective gas nozzle 1 is with elbow
Pipe, baffle plate mounting groove 7 is provided with the side of the tube wall tube wall of protective gas nozzle straight tube, in the upper and lower protective gas spray of mounting groove
It is respectively equipped with that a row amount is equal, positional symmetry fumarole 6 on mouth tube wall；As shown in figure 4, baffle plate 2 is T-type structure, can be with
It is directly installed in the mounting groove of above-mentioned protective gas nozzle, it is convenient to install and dismantle, light hole 8 is provided with baffle center, use
In one layer of two-sided colloid 3 is provided with by the lower surface of laser beam, baffle plate, colloid is from 3M7812 types white double faced adhesive tape, material
Kapton film silica gel, the characteristic with corrosion-and high-temp-resistant, colloid center is provided with the light hole mutually big on an equal basis with baffle position；Protect
The one end for protecting gas nozzle is blind end, and its other end is connected with extraneous protective gas appendix 4, and connector 5 is located at protection gas
