Abstract
The utility model discloses a tungsten electrode argon-arc welding electric arc oscillator, which comprises a casing and a coil, wherein the coil is wound on a coil framework which is fixed in the casing in sleeved mode, and the casing is fixed on a welding gun through a connecting support. A magnetic boot is installed in an axial center hole of the coil framework, and the end portion of the magnetic boot is close to a tungsten electrode pin of the welding gun. The axis of the coil framework is parallel or perpendicular to the axis of the tungsten electrode pin of the welding gun. The tungsten electrode argon-arc welding electric arc oscillator utilizes a computer to control the size, the direction and the residence time of coil current, namely controls the oscillation amplitude and oscillation frequency of the welding electric arc and the residence time of the welding electric arc on the edge and in the middle of the oscillation amplitude, enables the performance of welding weld joints to meet various technical requirements, and is novel in design, simple in structure and easy to popularize and implement.
Description
One. technical field: the utility model relates to a kind of welding arc wig-wag, particularly relates to a kind of argon tungsten-arc welding electric arc wig-wag that utilizes electromagnetic principle.
Two. background technology: at present; Known argon tungsten-arc welding electric arc wig-wag is the mechanical type wig-wag; Promptly utilize the motor-driven mechanical mechanism; Make the tungsten argon arc welding gun carry out the machinery swing or make tungsten electrode carry out machinery and swing, control the hunting frequency and the amplitude of fluctuation of welding gun or tungsten electrode through the amplitude of fluctuation of regulating motor speed and mechanical actuating mechanism, thereby reach the hunting frequency and the amplitude of control electric arc.Its shortcoming is that device structure is complicated, and the hunting frequency of electric arc and amplitude adjusted are inconvenient, particularly can not in welding process, accurately control and regulate in real time frequency, amplitude and both sides that rest on the electric arc amplitude of oscillation arbitrarily or middle time that electric arc is swung.
Three. the utility model content:
The utility model technical problem to be solved is: overcome the deficiency of prior art, a kind of modern design is provided, utilizes electromagnetic principle to realize electric arc swing and ability real-time regulated electric arc amplitude of fluctuation, hunting frequency and the argon tungsten-arc welding electric arc wig-wag of electric arc time of staying in swing process.
The technical scheme of the utility model is: a kind of argon tungsten-arc welding electric arc wig-wag; Contain shell and coil; Said coil is wrapped on the coil rack, and said coil rack suit is fixed in the said shell, and said shell is fixed on the welding gun through connecting support; The magnetic boots are installed in the axle center hole of said coil rack, and the end of said magnetic boots is near the tungsten electrode pin of welding gun.
The parallel axes of the axis of said coil rack and the tungsten electrode pin of welding gun or vertical.
The beneficial effect of the utility model is:
1, the utility model utilizes electromagnetic principle to realize the electric arc swing, rather than leans on the swing of welding gun machinery to drive the electric arc swing, thereby realizes electric arc swing truly itself.
2. the utility model is in welding automatically; Through size, direction and the time of staying of the coil current that computerizeds control; The amplitude of oscillation, hunting frequency and the electric arc that can control welding arc are in amplitude of oscillation edge and the middle time that stops; Make the welded seam performance reach various specification requirements, automatic welding field is had great practical significance.
3, the parallel axes of the axis of the utility model coil rack and welding gun tungsten electrode pin or vertical, the termination of magnetic boots are convenient to the electric arc swing near the tungsten electrode needle point.
4. the utility model is novel in design, simple in structure, and its scope of application is wide, is easy to promotion and implementation, has favorable economic benefit.
Four. description of drawings:
Fig. 1 is one of structural representation of argon tungsten-arc welding electric arc wig-wag;
Fig. 2 be argon tungsten-arc welding electric arc wig-wag structural representation two;
Fig. 3 is the right TV structure figure of argon tungsten-arc welding electric arc wig-wag shown in Figure 2.
Five. the specific embodiment:
Embodiment one: referring to Fig. 1, among the figure, 1-connects support, 2-coil, 3-coil rack, 4-magnetic boots, 5-shell, 6-welding gun, 7-tungsten electrode pin.
Argon tungsten-arc welding electric arc wig-wag contains shell 5 and coil 2; Coil 2 is wrapped on the coil rack 3; Coil rack 3 suits are fixed in the shell 5; Shell 5 is fixed on the welding gun 6 through connecting support 1, and magnetic boots 4 are installed in the axle center hole of coil rack 3, and the end of magnetic boots 4 is near the tungsten electrode pin 7 of welding gun 6.The parallel axes of the tungsten electrode pin 7 of the axis of coil rack 3 and welding gun 6.
During work; Coil 2 logical direct currents, the magnetic field of coil 2 generations at this moment is collected at the two ends of magnetic boots 4, makes magnetic boots 4 two ends produce stronger magnetic field; Meeting and have an effect in the magnetic field that the welding arc of the tungsten electrode pin 7 of this magnetic field and welding gun 6 itself produces, makes welding arc generation beat.Change the size of coil 2 electric currents, can change the welding arc amplitude of fluctuation, the electric current that coil 2 passes through is big; The angle of welding arc beat is just big, changes the sense of current through coil 2, and the beat direction of welding arc also changes thereupon; In the middle of coil 2 obstructed overcurrent, welding arc rest on.Welding arc has just formed constantly and has swung back and forth when constantly changing the sense of current of coil 2.
So, utilizing direction, size, conduction time and the stop conduction time of computer program control coil 2 through DC current, the amplitude of oscillation, wobble frequency and the welding arc of also just having controlled welding arc rest on the time of left, center, right.
Embodiment two: referring to Fig. 2 and Fig. 3, present embodiment and embodiment one are basic identical, and something in common does not repeat, and difference is: the axis normal of the tungsten electrode pin 7 of the axis of coil rack 3 and welding gun 6.
Change the concrete structure of magnetic boots, the concrete structure that changes shell and the concrete connected mode between change magnetic boots and the shell and can form a plurality of embodiment, be the common variation of the utility model, do not detail one by one at this.
