Detailed description of the invention
Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
See accompanying drawing 1, Fig. 2, the present invention is a kind of multifunction laser cutting head for laser cutting machine, by valve 1, screening glass mount pad 2, coupling nut 3, alignment pin 4, screening glass trim ring 5, fixed cover 6, focus on microscope base 7, packing ring 8, trim ring 9, water-cooling ring 10, quick connector 11, spring pressure bar 12, adjusting ring 13, spring housing 14, spring 15, shift(ing) ring 16, regulating sleeve 17, drive pin 18, coupling nut 19, cutting head connector 20, connecting plate 21, dynamic cover 22, trim ring 23, packing ring 24, pad 25, swivel nut 26, locking nut 27, adjusting screw(rod) 28, adapter 29, 3rd air chamber 30, second air chamber 31, first air chamber 32, focus lamp 33, screening glass 34 forms.Integral cutting head is based on fixed cover 6, and fixed cover 6 is fixed on above cutting head connector 20 and connecting plate 21 by coupling nut 19.Below fixed cover 6, be connected to screening glass mount pad 2, screening glass mount pad 2 is fixed by coupling nut 3, screening glass mount pad 2 is embedded with alignment pin 4, fixed cover 6 has groove, so that location when installing.In the bottom of screening glass mount pad 2, valve 1 is housed, screening glass mount pad 2, built with screening glass 34, is fixed with screening glass trim ring 5.Water cooling function part is by quick connector 11, and spring pressure bar 12, adjusting ring 13, shift(ing) ring 16, water-cooling ring 10, focus on microscope base 7, focus lamp 33, packing ring 8 and trim ring 9 form.Wherein shift(ing) ring 16 has four threaded openings, in " ten " word, 2 quick connectors 11 and 2 adjustment depression bars 12 is housed respectively, each quick connector and an adjustment depression bar correspondence.In one group of correspondence, quick connector 11 is connected on spring pressure bar 12, and spring pressure bar 12 is hollow, and there is water channel the inside, and in succession quick connector 11 in one end, the other end is connected on water-cooling ring 10, and water-cooling ring 10 is enclosed within the outside focusing on microscope base 7.On focusing microscope base, the position that the hollow water channel of spring pressure bar 12 faces, has groove, forms cooling-water duct.After cooling water is full of this part space, then flow out from another one spring pressure bar 12, both are orthogonal.Focus lamp 33 is arranged on and focuses in microscope base 7, is lined with packing ring 8 above, and is fixed by trim ring 9.Cooling water flows in tank, is cooled and focuses on microscope base 7, same mode, focus on microscope base 7 also in thermo-conducting manner by heat conducting mode, and cooling focus lamp 33, realizes the function of water-cooled.
Air-cooling function part is by fixed cover 6, and screening glass mount pad 2, screening glass 34, screening glass trim ring 5, dynamic cover 22, focus on microscope base 7, focus lamp 33, water-cooling ring 10 and adapter 29 form.In the bottom of fixed cover 6, have screw socket, one end of adapter 29 is connected on this screw socket, and the other end connects the quick connector of refrigerating gas.In the inside of fixed cover 6, by fixed cover 6, screening glass 34, screening glass trim ring 5, focus lamp 33, focuses on microscope base 7 and dynamic cover 22 forms the first air chamber 32.Refrigerating gas through adapter 29 directly enters this air chamber.By heat conducting mode, the lower surface of cooling focus lamp.In the bottom of dynamic cover 22, have an aperture, after refrigerating gas is full of the first air chamber 32, through this aperture, flow to the second air chamber, the second air chamber is by the outer surface of water-cooling ring 10, and the bottom of dynamic cover 22 and below inwall, focus on microscope base 7 and form.Second air chamber is that refrigerating gas flows to the place of focus lamp 33 upper surface transition.After refrigerating gas is full of the second air chamber 31, enter the 3rd air chamber 30 from the opening focused on above microscope base 7.At the 3rd air chamber 30, refrigerating gas is by heat conducting mode, and the upper surface of cooling focus lamp 33, is then upwards full of gradually.After being full of the 3rd air chamber 30, forming malleation with the external world, discharge gas by gap, make extraneous dust cannot enter into the 3rd air chamber, play the effect that local is dust-proof.
Described fixed cover 6 has circular hole at a lateral surface, and drive pin 18 passes from circular hole, and one end is fixed on dynamic cover 22, and the other end is stuck in the rectangular thread of regulating sleeve 17.Regulating sleeve 17 is blocked by shift(ing) ring 16 below, and when regulating sleeve 17 rotates, dynamic cover 22 moves up and down, and then drives focus lamp to move up and down.Because valve 1 is connected in above fixed cover 6, when regulating sleeve 17 rotates, valve 1 does not move, and historical facts or anecdotes is now when the focusing function that valve 1 is fixing.Wholely below regulating sleeve 17 circumferentially evenly scribble digital calibration, " 0 ", in centre, left and right uniform labelling, to numeral " 5 ", has 10 little lattice between each adjacent numeral, and wherein numeral " 5 " shares, now " 0 " and " 5 " on same straight line.At shift(ing) ring 16 top edge, scribble isosceles triangle mark, the angle (wedge angle) of triangle two isosceles points to digital calibration.Rotate regulating sleeve 17, make focus lamp 33 move to minimum from the highest, measure the distance of focus lamp 33 movement, then read the number of division that triangular marker slips over, just can determine a ratio.And make the appropriate adjustments, make when amount of focus moves in the middle of whole stroke, triangle wedge angle just points to " 0 " graduation mark on regulating sleeve 17.Add man-hour when actual, according to reading and this ratio of reading mark, converse actual defocusing amount.Realize the function quantizing defocusing amount.
As previously mentioned, shift(ing) ring 16 has four threaded openings, in " ten " word, 2 quick connectors 11 and 2 adjusting screw(rod)s is housed respectively, a quick connector 11 and adjusting screw(rod) 12 correspondence.In one group of correspondence, spring pressure bar 12 one end is fixed on water-cooling ring 10, the other end is ined succession quick connector 11, and spring pressure bar 12 has the diameter at a position slightly large, just blocks the spring 15 being through spring pressure bar 12, the other end of spring 15 is blocked by spring housing 14, spring housing 14 is also through on spring pressure bar 12, and after spring housing 14, adjusting ring 13 blocks spring housing 14, adjusting ring 13 is also passed by spring pressure bar 12, and it is fixed in a screw socket of shift(ing) ring 16 by screw thread.Like this, spring 15 is compressive state between spring housing 14 and spring pressure bar 12, and masterpiece is used on water-cooling ring 10.On the opposite of spring pressure bar 12, there is an adjusting screw(rod) 28, water-cooling ring 10 is withstood in its one end, the other end is fixed on a screw socket of shift(ing) ring 16 by swivel nut 26, adjusting screw(rod) 28 outermost has locking nut 27, like this, when rotating adjusting screw(rod) 28, just can promote water-cooling ring 10 that this side up is mobile, drive focus lamp 33 that this side up is mobile.Realize the adjustment on this direction.Same reason, in horizontal plane, vertically this side up, also has the adjusting device that a group identical with it, realize locomotive function.So far, realize in the bidimensional regulatory function of focus lamp 33 in horizontal plane.So far, repertoire realizes.
Obviously, above-mentioned example of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to technical scheme of the present invention the apparent change of extending out or variation be still in the row of protection scope of the present invention.
