Abstract
Provided is coaxial feeding powder head with high reflection power laser cladding, including a jointing sleeve, a centre-adjusting nut, a thread jointing sleeve, an inner taper sleeve and an outer taper sleeve. Out of the jointing sleeve two reducing cylinders with the constant external thread root diameters are arranged, the upper ends of the cylinders are connected with a processor, the lower ends are connected with the centre-adjusting nut, and the cylinders are closely locked via a collar nut. Four adjusting screws are uniformly distributed all-around the centre-adjusting nut. Out of the thread jointing sleeve two reducing cylinders with the constant external thread root diameters are arranged, the outside diameter of the thread jointing sleeve is arranged inside of the centre-adjusting nut and closely locked via a collar nut and the position is adjusted by a centre-adjusting screw. The adjusting screw is arranged at the smaller end of the thread jointing sleeve and is connected with the inner taper sleeve and the outer taper sleeve. The inner taper sleeve and the outer taper sleeve are connected by a screw and an adjusting washer is arranged between the inner taper sleeve and the outer taper sleeve. A cold water sink, an taper inner wall and an outer wall are arranged inside the inner taper sleeve and a nose cone is in bolt connection to the front end of the inner temper sleeve. The utility model has the advantages that the distance from the feeding point and the distance from focal point can all be adjusted, the powder can be uniformly fed and the like.
Description
Technical field
The utility model relates to a kind of powder-feeding head.
Background technology
Present existing powder conveyer is the gravity powder feeding, its principle is to rely on focusing on certainly in the pipeline of powder itself to flow, reach the purpose of powder feeding, when its shortcoming is that the friction when powder and pipeline reaches certain numerical value, powder just can not form in pipeline from main flow, has had a strong impact on the quality of processing like this.External product also exists minute surface and uses problem, has consumed work-ing life greatly, has increased production cost.
In view of the situation that does not also have perfect powder conveyer in the present field of laser processing, the slip-stick artist of my continent laser suite of equipment company limited has developed a kind of reflection coaxial focusing power feed head in conjunction with many-sided practical application experience.
Summary of the invention
The purpose of this utility model is to provide a kind of reflection co-axial powder-feeding head, and this powder-feeding head can be finished instant powder feeding, evenly powder feeding, interior among a small circle adjustable focal length.
The technical scheme that adopts is:
Reflection high-power laser cladding coaxial powder feeding head comprises a coupling sleeve, aligning nut, thread connection cover, inner conical drogue and external conical sleeve.Described coupling sleeve, outside are two cylinders that the reducing root diameter is constant, and its upper end links to each other with processing machine, and the lower end links to each other with the aligning nut and locks with ring nut then; Four equally distributed set screw are arranged around the described aligning nut; Described thread connection cover outside is two cylinders that the reducing root diameter is constant, the outside diameter of thread connection cover is installed in the inside of aligning nut, and locked by ring nut, come adjustment by the aligning screw to its position, the small end of thread connection cover has the adjustment nut, this adjustment nut links to each other with external conical sleeve with inner conical drogue, and inner conical drogue connects by screw with external conical sleeve, is provided with the adjustment packing ring between interior external conical sleeve; Cold rinse bank is arranged in the inner conical drogue, conical inboard wall and outer wall, front end is bolted with nose cone.External conical sleeve and inner conical drogue form a ring cone powder feeding flow passage chamber, and a cold water zones is arranged itself, and outer wall is processed with powder feeding pipeline and two-way water-cooled open holes.
The utility model has the advantages that:
1, this device powder feeding point distance is adjustable, and adjustable distance is 0～10mm;
2, the focal length of this device is adjustable, and adjustable distance is 0～8mm;
3, evenly powder feeding because this device adopts four direction powder feeding simultaneously, guarantees the homogeneity of powder sending quantity to a certain extent;
4,, effectively prevented owing to the reflection of the laser powder curing phenomenon that causes of being heated produces in cavity to the dual water-cooling system in powder feeding chamber;
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Reflection high-power laser cladding coaxial powder feeding head comprises a coupling sleeve 1, aligning nut 2, thread connection cover 3, inner conical drogue 4 and external conical sleeve 5.Coupling sleeve 1 one ends link to each other with processing machine 6, and coupling sleeve 1 outside is two cylinders that the reducing root diameter is constant, and the upper end of coupling sleeve 1 links to each other with aligning nut 2, then with ring nut 7 lockings.Around the aligning nut 2 four equally distributed set screw 8 are arranged, can realize the purpose of aligning.Thread connection cover 3 is that the outside is two cylinders that the reducing root diameter is constant, the outside diameter of thread connection cover 3 is installed in the inside of aligning nut 2, locked with ring nut 9, come adjustment by aligning screw 8 to its position, the small end of thread connection cover 3 has the nut 10 of adjustment, adjusts nut 10 and links to each other with external conical sleeve 5 with inner conical drogue 4.Adjust nut 10 and thread connection cover 3 and can do interior among a small circle rotation respectively, in order to adjust the drop point of powder.Inner conical drogue 4 and external conical sleeve 5 connect by screw, and 4,5 of interior external conical sleeves are provided with adjusts packing ring 13, regulates the gap of the two with this adjustment packing ring 13, changes the space size of powder runner.In the inner conical drogue 4 cold rinse bank is arranged, conical inboard wall and outer wall, the inwall of the outer wall of taper and external conical sleeve 5 forms the powder flow passage chamber, and front end is bolted with nose cone 11.External conical sleeve 5 itself has a cold water layer, and outer wall is processed with four powder feeding pipelines and two-way water-cooled open holes.Four powder conveying pipe, become 90 degree processing, adopt copper pipe 12 welding, can realize even powder feeding, the two path water cooling system, the water circuit system effect of inner conical drogue 4 is that the heat that produces when portion's laser is within it carried cools off, and the effect of the cold water layer of external conical sleeve 5 is that laser is cooled off to the heat on the powder-feeding head by the workpiece diffuse-reflectance adding man-hour.
