Abstract

The utility model discloses a manual argon tungsten-arc welding gun, which is provided with a gun body. The gun body is provided with a handle, an operator can hold the handle by hands, inner threads at the rear of the gun body are connected with a tail sleeve, outer threads are arranged on a transverse rod of the gun body, the outer threads of the transverse rod of the gun body are sleeved with a gun head jacket, a connecting pipe is further sleeved between the gun head jacket and the gun body, a red copper pipe and a tungsten needle penetrating into the red copper pipe are disposed in the gun body, and a gun head positioning nozzle is sleeved at the front end of the gun body. The manual argon tungsten-arc welding gun can be operated by unskilled welders, only the tungsten needle needs to be adjusted and aligned to a welding position before welding, work efficiency is improved, the welding gun can be used for welding without alignment of the needle during welding, needle grinding time is shortened, the efficacy of an unskilled welder can be approximately three times higher than that of a normal skilled welder by the aid of the manual argon tungsten-arc welding gun, the welding gun is economical, the working distance from the tungsten needle to a workpiece can be fixed by a welding nozzle, the workpiece cannot contact with the tungsten needle, so that abrasion of the tungsten needle is reduced, needle grinding time is saved, needle grinding facilities are omitted, and rejection rate is decreased.

Description

A kind of GTAW welding gun

Technical field

The utility model relates to a kind of welder when being used for two workpiece points and connecting, and particularly relates to a kind of GTAW welding gun.

Background technology

At present, when the welding of adopting manual argon arc welding to carry out pipeline section is produced, not only require the welder to have higher technical skills, and hand labour intensity is big, welding efficiency is low, and appearance of weld is difficult to control, all can not satisfy the production needs of little cost unit.Because argon tungsten-arc welding is the accessory that the most often is used in the jointing metal sheet, and because in it is used, the welder can handle quite light little component parts easily; So the welder often need spend the time intercropping of its part and clean; Composite set fixing with operational processes such as rosin joint, and except the hand skill of needs height, patient training is with beyond the welding bead that obtains better quality; Sometimes welding tool has the technology of machinery, and the sub-assembly that will weld does suitable combination and device is fixing.

Using traditional-handwork argon tungsten-arc welding welding gun to weld and producing is to need skilled welder to carry out, and when the workman operates, both hands from empty, and darg gets off, two hand soreness.And some private enterprise because of please less than or please do not play skilled argon arc welder and deeply hurt, even be forced to stop production.Therefore, how reforming existing GTAW welding gun is the technical barrier that current needs solve in order to replace skilled argon arc welder.

Summary of the invention

The purpose of the utility model is to provide a kind of GTAW welding gun of new structure, and its tip is light and handy, easy accessibility, and is simple in structure, is specially adapted to the special welding and the exterior components welding of factory, and is very practical.

The purpose of the utility model and to solve its technical problem be that technical scheme below adopting realizes.A kind of GTAW welding gun according to the utility model proposes has a rifle body, this rifle body have one can supply the people to hold handle, the back internal thread of said rifle body is connected with the afterbody sleeve pipe; This rifle body transverse bar portion is provided with external screw thread, and this rifle body transverse bar portion outside thread bush is connected to rifle head overcoat; Between this rifle head overcoat and rifle body, also be socketed with tube connector; This rifle body set inside has copper tube, and penetrates the inner tungsten pin of this copper tube; The front end sleeve of this rifle body is connected to rifle head location mouth.

According to the GTAW welding gun of the utility model embodiment, the top of said rifle head location mouth is provided with a screw, has a housing screw to pass this screw, and can copper tube and inner tungsten pin thereof be fixed.

According to the GTAW welding gun of the utility model embodiment, the openend dual-side of said rifle head location mouth is the opening parabolic shaped structure left of symmetry.

According to the GTAW welding gun of the utility model embodiment, the openend dual-side of said rifle head location mouth is opening " U " type structure left of symmetry.

According to the GTAW welding gun of the utility model embodiment, said rifle head overcoat is a ceramic material; Said tube connector is the polytetrafluoroethylene (PTFE) material.

By technique scheme, the advantage that the utility model GTAW welding gun has is:

The utility model does not require that skilled welder just can operate, as long as adjustment tungsten pin before the weldering is aimed at the welding position and just become; Improved operating efficiency, need not be during work to pin, just pick up and can weld, reduce the card grinding time, comparable normal skilled worker improves about three times of effects; Practice thrift, the operating distance of tip ability fixed tungsten pin and workpiece, workpiece and tungsten pin can not collided, and that just can practice thrift the tungsten pin, saves card grinding time and card grinding auxiliary facility, reduces percent defective.

The specific embodiment

See also shown in Fig. 1～3, the GTAW welding gun of the utility model, it has a rifle body 10, this rifle body 10 have one can supply the people to hold handle 11.The back internal thread of this rifle body 10 is connected with afterbody sleeve pipe 20.These rifle body 10 transverse bar portions are provided with external screw thread 12; This rifle body 10 transverse bar portions outside thread bush is connected to rifle head overcoat 30, and this rifle head overcoat 30 is a ceramic material.Between this rifle head overcoat 30 and rifle body 10, also be socketed with tube connector 40, this tube connector 40 plays the effect that rifle head overcoat 30 is fastened on rifle body 10 cross bars outside for the polytetrafluoroethylene (PTFE) material is made.

These rifle body 10 set inside have copper tube 50, and penetrate the tungsten pin 60 of these copper tube 50 inside.The front end sleeve of this rifle body 10 is connected to rifle head location mouth 70.The top of this rifle head location mouth 70 is provided with a screw, has a housing screw 80 to pass this screw, and can copper tube 50 and inner tungsten pin 60 thereof be fixed.The openend dual-side of this rifle head location mouth 70 is the opening parabolic shaped structure left of symmetry.The location mouth design of this structure can obviously reduce the injury of arc light to eyes and skin, and the location mouth covers most of arc light, as long as protect slightly, does not just have injury.

In addition; Its rifle body 10 front ends of the GTAW welding gun of the utility model also can be set up the rifle head location mouth 70 ' of another version; The top of this rifle head location mouth 70 ' is provided with a screw; There is a housing screw 80 ' to pass this screw, and can copper tube and inner tungsten pin thereof be fixed, shown in Fig. 4 A and Fig. 4 B.The openend dual-side of this rifle head location mouth 70 ' is opening " U " type structure left of symmetry.The location mouth of this kind structure welds easily, it be one very simple, but very practical be attached to the parts on the argon-arc welding gun.

Can be according to the drawing needs, curve-straight line walking: the location mouth of the distance of fixed tungsten pin and workpiece, appearance is slick and sly, as long as by drawing, accomplishes simple pattern, just can weld by going.Can reduce staff's labour intensity, as using the argon arc welding location mouth of the utility model, welding gun can be placed on the workpiece and slide, and just can reduce the arduous of workman.

The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; So every the utility model technical scheme content that do not break away from, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
