Description
Technical field
The utility model relates to field of laser cladding, particularly a kind of endoporus laser melting coating head.
Background technology
Laser melting coating refers to and is made it to melt with matrix surface skim through laser irradiation by coated material cladding matrix surface placed by selecting with different adding material modes simultaneously, and it is extremely low to form extent of dilution after rapid solidification, the top coat of metallurgical binding is become with matrix, the remarkable processing method improving the wear-resisting, anti-corrosion, heat-resisting, anti-oxidant of substrate surface and electrical specification, thus reach the object of surface modification or reparation, both meet the requirement to material surface specified property, again save a large amount of noble elements.
With built-up welding, spraying, plating and gas phase sediment-filled phase ratio, laser melting coating has that extent of dilution is little, dense structure, coating and matrix is combined, be applicable to that cladding material is many, granularity and the feature such as content is large, and therefore laser melting and coating technique application prospect is very wide.
Existing laser melting coating head is mainly used in the cladding of outer surface of workpiece, inner hole of workpiece due to size narrow and small, need the inner hole cladding head of design specialized, just can reach good cladding effect.
Summary of the invention
The purpose of this utility model is by the Curve guide impeller to laser melting coating head, makes its applicable inner hole laser cladding.
The purpose of this utility model is achieved through the following technical solutions:
A kind of endoporus laser melting coating head, comprise the laser head body with optical fiber interface and laser beam light-emitting window, it is characterized in that: in described laser head body, be also provided with collimating mirror, condensing lens, speculum, protective glass, powder feeding passage, cooling-water duct and protection gas passage, described protective glass is arranged in described laser beam light-emitting window, described collimating mirror is located in described optical fiber interface, described laser beam light-emitting window is arranged on the side of described laser head body front end, the meal outlet of described powder feeding passage is also arranged on described laser head body front end, and be positioned at same side with described laser beam light-emitting window.
The ramp way that described powder feeding passage comprises the horizontal channel substantially parallel with described laser head body and is communicated with this horizontal channel, described meal outlet is positioned at ramp way outlet.
Described laser head body is provided with cooling water inlet pipe, cooling water outlet pipe and protection gas inlet pipe.
After laser beam is derived from optical fiber, through collimation, focus on, then by speculum, beam direction is changed 90 °, through protective lens, be radiated on workpiece.
In the side of cladding head, be provided with water coolant and shielding gas passage.Water coolant is mainly used to cool collimating mirror, condensing lens, speculum and protective glass; Shielding gas is mainly used to protect molten bath, and is blown away by the flue dust produced in cladding process, prevents protective lens contaminated.
Cladding head opposite side, is provided with powder feeding interface, and powder, through powder feeding passage, is sent by paraxonic nozzle, points to laser beam.During cladding, laser beam melts powder, forms cladding layer.
Inside workpiece can be stretched in cladding head end by the utility model, and laser beam light-emitting window and meal outlet are arranged on the same side of laser head body front end, thus conveniently cladding head is goed deep into the processing completing endoporus in endoporus, is applicable to very much the endoporus cladding of workpiece.
