Description
Technical field:
The present invention relates to technical field of welding equipment, refer in particular to a kind of laser compound welding tip device.
Background technology:
In fields such as petrochemical industry, Aero-Space, military affairs, automobile makings, the sealing on the parts such as pipeline, housing, body of a motor car or the welding of non-closed curve weld seam often form by the shorter weld seam welding of multistage.Hybrid Laser-Arc Welding is a kind of solder technology that speed is fast, distortion is little, the material fire damage is few, welding quality is high of welding.For yielding thin-wall workpiece, especially when material was heat-sensitive material such as aluminium alloy, titanium-alloy thin-plate, adopting hybrid Laser-Arc Welding was to select preferably.When carrying out hybrid Laser-Arc Welding, laser torch is prolonged weld seam and is advanced, and arc torch is positioned on the tangential direction of seam track.Therefore, when the welding curve, arc torch needs constantly to rotate around laser torch, to guarantee that arc torch is positioned on the tangential direction of seam track all the time.When welding during a closed curve weld seam, require arc torch to do 360 ° of rotations around the laser beam of self laser torch.
Existing composite welding head is usually at the welding of spot welding, straight bead or simple non-closed curve weld seam., can not reach once welding and finish closed curve weld seam requirement of welding often by multiple welding, be spliced by many weld seams for the welding of closed curve weld seam, production efficiency is low, and welding quality is difficult to guarantee.For example: Chinese invention patent " rotary double focus laser---MIG electric arc composite welding head " (patent No.: CN200410069000.3) designed a kind of by connecting plate, electric rotating machine, auxiliary connection, the laser spot rotating mechanism that the lifting connecting cylinder constitutes, but can only make the laser double focus point near weld seam, do the rotation of similar ellipse, though can adapt to the welding of the camber line weld seam of certain angle, can not finish the big particularly welding of closed curve weld seam of angle.Germany KUKA company has also developed a kind of compound welding tip device, can make arc torch around 200 ° of laser torch focus rotations by 7 interlocks, can finish the welding of general curve weld seam, but still can not finish the welding of closed curve weld seam.Therefore in a hurry need a kind of arc torch can do the laser compound welding tip device of 360 ° of rotations now around the laser beam of self laser torch.
Summary of the invention:
Purpose of the present invention is exactly the defective at present laser compound welding tip device, provides a kind of arc torch can do the laser compound welding tip device of 360 ° of rotations around the laser beam of self laser torch.
For achieving the above object, adopt following technical scheme:
A kind of laser compound welding tip device, it is made up of casing, composite welding head, joint cover, bull gear, sleeve, pinion and motor, composite welding head, joint cover, sleeve, bull gear all are installed in the casing, wherein composite welding head is installed on the joint cover, joint cover is fixedlyed connected with the sleeve of hollow, sleeve is connected in the bull gear with one heart, and bull gear is connected with pinion, and the driving shaft that the pinion motor outer with being fixed on casing extends in casing is connected.
Wherein said composite welding head is made up of laser torch and arc torch, and described laser torch is arranged on the central shaft of sleeve.
The all sides of wherein said casing offer an observation panel at least.
Beneficial effect of the present invention is: motor rotation drives bull gear by pinion, simultaneously with the fastening with one heart also running together of sleeve of bull gear, joint cover is fixedlyed connected with the sleeve of hollow, and laser torch and arc torch are installed on the joint cover, and laser torch is arranged on the central shaft of sleeve.So arc torch is done 360 ° of rotations around the laser beam of laser torch in rotation process.By the running of control motor, can control the rotating speed and the rotational angle of composite welding head, make composite welding head can adapt to the welding of the curved welding seam of different curvature or curvature variation.
Description of drawings:
Fig. 1: be structure cutaway view of the present invention
Fig. 2: be the structure cutaway view of another direction of the present invention
Fig. 3: be vertical view of the present invention
The specific embodiment:
The present invention is described further below in conjunction with accompanying drawing:
As shown in Figure 1, 2, 3: a kind of laser compound welding tip device, it is made up of casing 1, joint cover 2, composite welding head 3, motor 4, bull gear 5, pinion 6 and sleeve 7, joint cover 2, composite welding head 3, bull gear 5, pinion 6 and sleeve 7 all are installed in the casing, wherein composite welding head 3 is installed on the joint cover 2, joint cover 2 is fixedlyed connected with the sleeve 7 of hollow, sleeve 7 is connected in the bull gear 5 with one heart, bull gear 5 is connected with a joggle with pinion 6, pinion 6 be fixed on the driving shaft that casing 1 motor 4 outward extends be connected in casing.
Wherein said composite welding head 3 is made up of laser torch 31 and arc torch 32, and described laser torch 31 is arranged on the central shaft of sleeve 7.
Wherein said casing 1 all sides offer an observation panel 11 at least.
Whole laser compound welding tip device is installed on the lathe by casing 1 in the use, motor 4 drives bull gear 5 runnings by pinion 6, simultaneously with the fastening with one heart also running together of sleeve 7 of bull gear 5, joint cover 2 is fixedlyed connected with the sleeve 7 of hollow, laser torch 31 and arc torch 32 are installed on the joint cover 2, and laser torch 31 is arranged on the central shaft of sleeve 7.So arc torch 32 is done 360 ° of rotations around the laser beam of laser torch 31 in rotation process.By the running of control motor 4, can control the rotating speed and the rotational angle of composite welding head 3, make composite welding head 3 can adapt to the welding of the curved welding seam of different curvature or curvature variation.
Certainly, the embodiment of the above is a preferred embodiments of the present invention, is not to limit the scope of the present invention, so all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify, and are included in the present patent application claim.
