Further, in the present embodiment, the inwall of one end that air flow chamber 200 is placed in adapter sleeve 100 is provided with pressurized ring 230.First end face 322 near the excalation of air flow chamber 200 near the part of the second cylindrical shell 310 and the second cylindrical shell 310, makes cutting head seat 300 near the internal diameter of one end of air flow chamber 200, reduces gradually from the first end face 322 place.Wherein, the internal diameter that cutting head seat 300 is positioned at the first end face 322 place is identical with the internal diameter of pressurized ring 230, and the first end face 322 contacts with pressurized ring 230.Air flow chamber 200 coordinates with cutting head seat 300, thus is convenient to gas and flows in cutting head seat 300 from air flow chamber 200, and the first end face 322 can be made to have suitable contact area with pressurized ring 230.
Further, in the present embodiment, the edge disappearance formation first step 1322 of end face 132 away from barrel 120 is carried.Second end face 324 forms second step 3242 away from the edge disappearance of the second cylindrical shell 310.First step 1322 engages with second step 3242.The structure of carrying end face 132 and the second end face 324 makes adapter sleeve 100 pairs of cutting head seats 300 have certain support force, and can ensure that cutting head seat 300 can in adapter sleeve 100 movement preferably.
Be appreciated that in other embodiments, carrying end face is near the edge of barrel disappearance formation first groove.Second end face is near the edge of the second cylindrical shell disappearance formation second groove.Second end face contacts with the bottom land of the first groove away from the edge of the second cylindrical shell, and carrying end face contacts with the bottom land of the second groove away from the edge of barrel.
Further, in the present embodiment, cutting head 400 and cutting head seat 300 are spirally connected.Also namely cutting head 400 and the second cylindrical shell 310 are spirally connected, concrete, are respectively equipped with screw thread on the outer wall of cutting head 400 with on the inwall of the second cylindrical shell 310.Thus the distance between the light-emitting window 410 of cutting head 400 and cutting head seat 300 can be regulated.Also can regulate the distance between light-emitting window 410 and cutter member to be cut 20, make the distance between light-emitting window 410 and cutter member to be cut 20 arrive optimum distance, thus the cutting accuracy of above-mentioned cutting head device 10, cut quality and cutting efficiency can be improved further.
Further, in the present embodiment, for convenience of the distance regulated between light-emitting window 410 and cutter member to be cut 20, cutting head locknut 700 is sheathed on the outer wall of cutting head 400, and is spirally connected with cutting head 400, and cutting head locknut 700 is positioned at outside cutting head seat 300.By rotary cutting cutting torch locknut 700, cutting head 400 can be made to move on cutting head seat 300, thus regulate the distance between light-emitting window 410 and cutter member to be cut 20.
Further, in the present embodiment, the inwall of cutting head 400 caves in and forms anti-residue groove 420, and anti-residue groove 420 ringwise.When cutting cutter member 20 to be cut, the residue that cutting produces easily enters in cutting head 400 from light-emitting window 410, and then may pollute focusing lens.The inwall of cutting head 400 arranges anti-residue groove 420, effectively the residue entered in cutting head 400 can be reflected back light-emitting window 410, discharge from light-emitting window 410 place, thus available protecting focusing lens.
Slider 800 is hollow structure, is located in air flow chamber 200.The spacer portion 820 that slider 800 comprises connecting portion 810 and is connected with connecting portion 810, and spacer portion 820 is near cutting head seat 300.The outer wall of connecting portion 810 is connected with the inner wall sealing of air flow chamber 200, the outer wall of spacer portion 820 and the inwall interval of air flow chamber 200.
Air flow chamber 200 is for introducing gas.In the present embodiment, air flow chamber 200 is provided with the installing hole 240 for installing gas-tpe fitting.The center line of installing hole 240 and the central axis of air flow chamber 200.The number of installing hole 240 is multiple, and multiple installing hole 240 is equidistantly arranged.
Wherein, installing hole 240 is positioned at outside adapter sleeve 100, and between spacer portion 820 two ends.Thus the air flow energy at installing hole 240 place flows in the space that spacer portion 820 and air flow chamber 200 formed.
In traditional cutting head device, flow into the gas in air flow chamber 200, unrestricted choice flows to, and part flows into cutting head 400 downwards, and part upwards flows into and focuses on microscope base, causes the air velocity at light-emitting window 410 place of cutting head 400 lower.In the present embodiment, changing air flow direction by arranging slider 800, adding the air velocity at light-emitting window 410 place.
Said flow chamber 200, slider 800 and multiple installing hole 240 coordinate, and effectively can increase the air velocity at light-emitting window 410 place, thus add the energy at light-emitting window 410 place, and then effectively improve cutting accuracy, cut quality and cutting efficiency.Therefore, above-mentioned cutting head device 10 has accurate cutting accuracy, good cut quality and high-speed cutting efficiency.
