Wherein, evenly be provided with digital calibration on the whole circumference below the described regulating sleeve.
Wherein, the described circle that ends is provided with the isosceles triangle mark, and the angle of two isosceles of this triangular marker points to the digital calibration of regulating sleeve.
Wherein, described air chamber is the confined space that gas curtain forms piece and fixed cover formation.
Owing to taked above technical scheme, advantage of the present utility model is:
1 the utility model can cool off focus lamp two surfaces up and down, and cooling evenly.
2 the utility model are simple in structure, and are easy to operate.
3 when valve and workpiece relative position remain unchanged, and can change the defocusing amount of laser cutting, and defocusing amount can quantize to show, and be therefore easy to adjust, and the precision height.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the schematic diagram of the utility model regulating sleeve;
Fig. 3 ends the schematic diagram of circle for the utility model.
Among the figure: 1 fixed cover; 2 air chambers; 3 first fan-shaped openings; 4 air inlet quick connectors; 5 end circle; 6 lower gaskets; 7 regulating sleeves; 8 drive pins; 9 focusing barrels; 10 packing rings; 11 positive pressure gas secret rooms; 12 the 3rd fan-shaped openings; 13 pads; 14 focus lamps; 15 air flues; 16 second fan-shaped openings; 17 gas curtains form piece; 18 valves.
The specific embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Referring to accompanying drawing 1, Fig. 2, Fig. 3, the utility model is a kind of air-cooled laser cutting head that is used for laser cutting machine, comprises the axial adjustment funtion part, the gentle mouth portion of air-cooled funtion part.The axial adjustment funtion part only encloses 5 by overlapping 1 surely, lower gasket 6, and regulating sleeve 7, drive pin 8, focusing barrel 9, packing ring 10, pad 13 and focus lamp 14 are formed.Focus lamp 14 is contained in the focusing barrel 9, is pressed with pad 13 and packing ring 10 above.Surely overlapping has opening on 1, drive pin 8 passes the opening of deciding cover 1, and an end is fixed on the focusing barrel 9 by screw thread, and the other end is stuck in the square type thread groove of regulating sleeve 7.Regulating sleeve 7 can be withstood by lower gasket 6 below overlapping 1 outside rotation surely, and lower gasket 6 also is enclosed within decides cover 1 outside, and withstands by only enclosing 5, only encloses 5 by screw thread with overlap 1 surely and fix.Like this, rotary regulating sleeve 7 because regulating sleeve 7 has been axially fixed, axially moves along overlapping 1 inwall surely so drive pin 8 drives focusing barrel 9.Realize the axial adjustment function of focus lamp.Evenly scribble digital calibration on the regulating sleeve 7 below whole circumference, " 0 " in the centre, about each mark to numeral " 5 ", wherein numeral " 5 " is shared.Scribble the isosceles triangle mark on 5 only enclosing, the angle (wedge angle) of triangle two isosceles points to digital calibration.Rotate regulating sleeve 7, make focus lamp 14 move to minimumly, measure the distance that focus lamp moves, read the number of division that triangular marker slips over again, just can determine a ratio from the highest.And do suitable adjustment, make that the triangle wedge angle just points to " 0 " graduation mark on the regulating sleeve 7 when amount of focus moves in the middle of whole stroke.Add man-hour when actual, reading and this ratio according to the reading mark converse actual defocusing amount, realize quantizing the function of defocusing amount.
Air-cooled funtion part is by air inlet quick connector 4, and air chamber 2 overlaps 1 surely, focusing barrel 9, and gas curtain forms piece 17,3, the second fan-shaped openings 16 of first fan-shaped opening, 15, the three fan-shaped openings 12 of air flue and positive pressure gas secret room 11 are formed.Wherein, gas curtain forms piece 17 and is fixed on below the focusing barrel 9, and coaxial with it.Like this, focusing barrel 9, gas curtain form piece 17 and overlap 1 surely and form an airtight space, and this space is exactly an air chamber 2.Air inlet quick connector 4 is contained on the screw of deciding cover, and the opening of screw is facing to air chamber 2, and air chamber 2 has certain length, when focus lamp 14 is done axial adjustment, all can guarantee directly to enter air chamber 2 from the refrigerating gas of air inlet quick connector output, does not influence the air cooling function.Below focusing barrel 9, gas curtain forms piece 17 near air chamber 2 these tops on one side, and first fan-shaped opening 3 is arranged, and is exactly the outlet of refrigerating gas in the air chamber 2, and refrigerating gas from then on opening sprays at a high speed, forms gas curtain.High velocity air cools off the lower surface of focus lamp 14 in the mode of conduction.Enter air flue 15 from second fan-shaped opening 16 then, along air flue 15, again from the 3rd fan-shaped opening 12 ejections.The upper surface of cooling focus lamp 14.From the gas of the 3rd fan-shaped opening 12 ejections, be focused at the top of focus lamp 14 at last, form the space of positive pressure gas secret room 11.Since a large amount of accumulations of refrigerating gas, the air pressure in this space obviously greater than the external world, so gas only from then on the space flow to the external world.So can stop extraneous dust to enter, play the dustproof effect.
Obviously, above-mentioned example of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
