The specific embodiment
Combine Figure of description that the present invention is further described through embodiment below:
Referring to accompanying drawing 1, shown in 2: a kind of small-bore TIG (tungsten inert gas) surfacing torch, it comprises rifle body 1, is positioned at the rifle head 2 of rifle body 1 leading section, between rifle body 1 and the rifle head 2 through being rigidly connected; The connecting portion 18 that has rigidity between rifle body 1 and the rifle head 2; Be rigidly connected mutually through this connecting portion 18 between rifle body 1 and the rifle head 2, connecting portion 18 is wholely set with the holder 10 of rifle head 2, manages respectively therewith that connecting portion 18 is connected in the rifle body 1; And seal mutually through securing member, shown with reference to accompanying drawing 5,7.This type of is rigidly connected and can effectively reduces rifle body that welding gun when motion cause because of welding wire or tungsten electrode and workpiece bonding and damage or be out of shape.
Rifle body 1 comprises water cooled housing 3, coaxial pipe assembly, the insulating bushing 4 of interval between water cooled housing 3 and pipe assembly that is arranged in the water cooled housing 3.Pipe assembly and water cooled housing 3 insulate through insulating bushing 4 mutually, and insulating bushing 4 can be avoided electric conductor and outside to be connected to form the loop and influence the stability of welding.Water cooled housing 3 comprises inner and outer wall, between inside and outside wall, carries out the cold water circulation, and the external diameter of water cooled housing 3 is preferably smaller or equal to 45mm.The circular lining that has a plurality of circular holes in the middle of insulating bushing 4 can adopt; Each pipe in the pipe assembly is inserted in respectively in the different circular holes; The external peripheral surface of insulating bushing 4 is adjacent to the internal face of water cooled housing 3 mutually, can realize managing the mutually insulated of assembly and water cooled housing like this.
The pipe assembly comprise be used for to rifle head 2 places send into continuously welding wire wire-feeding pipe 5, be used for to rifle head 2 places send into protective gas protection gas circuit, electric conductor, be used for the water inlet pipe 8 and the return pipe 9 of cooling water circulation.Cooling water gets into water inlet pipe 8 and is flowed out by return pipe 9 through being arranged on circulating water chennel 19 in the rifle head 1 back of circulating, water inlet pipe 8 and return pipe 9 with the 2-4 liter/minute discharge circulate, be preferably in more than 3 liters/minute.In addition, electric conductor also is arranged in the return pipe 9; Wire-feeding pipe 5 is used for carrying and the protection welding wire.This water, electricity, gas pipe and wire-feeding pipe 5 be the structure in rifle body 7 all, can dwindle the whole physical dimension of welding gun; Water power tracheae and wire-feeding pipe 5 have also been protected in water cooled housing 3 inner cooling water circulations, have improved the continuous welding ability of welding gun.
Shown in accompanying drawing 3: rifle head 2 comprises holder 10, be arranged on holder 10 upper ends tungsten electrode folder 11, be clamped in tungsten electrode 12 on the tungsten electrode folder 11, be used at least tungsten electrode 12 and workpiece welding region are imported the protection conductance stream assembly of protective gas; Protection conductance stream assembly and the gas connection mutually of protection gas circuit, tungsten electrode 12 is electrically connected with electric conductor.Form the angle of 60 to 90 degree between rifle head center line 13 and the rifle body axial line 14; When rifle head center line 13 and rifle body axial line 14 were vertical, effect was optimum.Rifle body 1 just can satisfy under the prerequisite of support strength lengthening as far as possible like this, but has dwindled the diameter dimension and the depth dimensions of welder's part greatly, can realize that to postwelding internal diameter>=50mm the workpiece inwall of length≤1000mm carries out effective built-up welding.
The protection gas circuit comprises the first protection tracheae 6 and the second protection tracheae 7.Protection conductance on rifle head stream assembly comprises the first protection air chamber 20 and the second protection air chamber 21, be arranged in the first protection air chamber 20 and be looped around ring-type current divider 15 around the tungsten electrode 12, to be arranged on the second protection air chamber 21 interior and be positioned at the nozzle 16 of holder 10 lower ends.The first protection air chamber 20 is used for current divider 15 is connected with the first protection tracheae 6; Protective gas by the first protection tracheae 6 imports will be sent in the current divider 15 through the first protection air chamber 20; Import protective gas by 15 pairs of workpiece welding regions of current divider place; This partial protection gas imports protective gas to tungsten electrode 12 with workpiece welding region place and protects; The structure of current divider 15 is as shown in Figure 4, and its lower end has a plurality of breach, and the protective gas in the first protection air chamber 20 is sent to the welding region place of workpiece through these breach.Nozzle 16 is arranged on holder 10 lower ends, is used for the heat-affected zone around the workpiece welding region is imported protective gas.As shown in Figure 6; The second protection air chamber 21 is used for nozzle 16 is connected with the second protection tracheae 7; The protective gas that is imported by the second protection tracheae 7 like this will be sent in the nozzle 16 through the second protection air chamber 21; Nozzle 16 will protect gas blowout to because high-temperature soldering and the heat-affected zone that forms in the outside of workpiece weld, thereby this heat-affected zone is also formed protection.Because the heat-affected zone is the outside at weld, so nozzle 16 will be arranged on the outside of current divider 15.To relax from the protection gas of nozzle 16 ejections in order making, to be provided with air sifter cover 17 at the spout place of nozzle 16, air sifter cover 17 can effectively be controlled from nozzle 16 ejection protection gas and give vent to anger evenly, has improved welding quality.
When using welding gun to weld, tungsten electrode 12 is because the electric current that electric conductor imports produces electric arc, and welding wire is melted and accomplishes the welding to workpiece, meanwhile, can be protected tungsten electrode 12 and workpiece welding region by the protective gas that current divider 15 is derived.In addition, nozzle 16 ejection scopes are bigger, and the protection gas of its ejection can also spray protection gas to the heat-affected zone that produces owing to heat conduction in the welding process, thereby and this zone also protected.Therefore, in the present embodiment, importing to the protection period through two-way protection gas circuit can play a very good protection to welding region and heat affected area, thereby has improved welding quality.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
