Background technology
In the supporting welding of metal tube and flange, generally by welder, use electric welding machine that the pipeline of working good and ring flange are realized to welding.Main what adopt is argon arc welding, and its main frame produces high-frequency electrical, and the welding wire of welding gun head contacts with weldment, due to high frequency electric formation high frequency magnetic field, makes the thawing of generating heat rapidly of weldment and welding wire, reaches the welding object of pipe fitting.The argon gas of the head of welding gun ejection simultaneously, the Main Function of argon gas is isolated air, protection solder joint can not react with airborne oxygen and other gaseous impurities in the process of welding, improves the welding quality of weld seam.And the metal joint of conventional cylinder flexible pipe circumferential weld automatic welding and flange size are often different, it is diameter and highly different, so flange need to be installed along vertical duct axis, make the axis conllinear of two weldments, corresponding workpiece is fixed on relative position, at this moment welder's hand torch carries out spot welding at the weld seam of weldment weld, realizes the preliminary fixing of two weldment relative positions, and welder is near at the uniform velocity the weld seam polishing of its elsewhere afterwards.Welder vertically places the pipeline welding again, then by inner weld seam polishing.But hand torch manually welds shortcoming:
First, welding adopts spot welding, welder to be difficult to guarantee that the size of solder joint is identical, continuity and the weldquality of weld seam.
Secondly, weldment belongs to surface of revolution workpiece, and welder must guarantee speed of welding at the uniform velocity, grasps the time of welding simultaneously, and overlong time easily burns out weldment, and the time is too short, and the sealing of weld seam welding is difficult to guarantee.
Utility model content
Solder joint weldquality is inhomogeneous for existing during artificial welding Conduit Joint in prior art for the utility model, weld seam welded seal and the poor deficiency of continuity, and a kind of special-purpose argon arc welding machine of pipe that can automatic welding is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
The special-purpose argon arc welding machine of pipe, comprises argon bottle, processing unit (plant), electric cabinet, wire-feed motor and flexible welding gun that installment work relation is installed, and the external cable of described electric cabinet is drawn by aerial plug-in unit female; Described processing unit (plant) comprises the support with hydraulic lifting cylinder, is horizontally installed with the hoistable platform of being controlled by hydraulic lifting cylinder on described support; Described hoistable platform top thrust bearing is installed and by alternating current generator by the shaft-driven helical teeth wheel disc of worm-drive, below is provided with scroll chuck and air motor; Described helical teeth wheel disc top is provided with welding gun fixture, and welding gun fixture and corresponding infrared inductor first and the infrared inductor second of being provided with on support.
Further, described welding gun fixture is installed fixing by left and right free degree adjusting nut and easy on and off degree adjusting nut.
Compared with prior art, the beneficial effects of the utility model are: the fixing position of weldment pipe, can guarantee good cooperation between two weldments; For different pipeline height, welding gun can vertical ground lift adjustment; Welding gun rotation adopts axially and free degree adjustable mechanism radially; The lifting of welding gun mechanism is directly to adopt hydraulic drive and chaindriven combination; Assurance welding wire is not looped, is not fractureed in the process of welding.Realize mechanical replacement and manually welded, greatly improved quality and the efficiency of welding.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
The special-purpose argon arc welding machine of pipe, comprises argon bottle 1, processing unit (plant) 2, electric cabinet 3, wire-feed motor 4 and flexible welding gun 6 that installment work relation is installed, and the external cable of described electric cabinet 3 is drawn by aerial plug-in unit female 5; Described processing unit (plant) 2 comprises the support 21 with hydraulic lifting cylinder 24, is horizontally installed with the hoistable platform 30 of being controlled by hydraulic lifting cylinder 24 on described support 21; The helical teeth wheel disc 28 that described hoistable platform 30 tops are provided with thrust bearing 29 and are driven by worm drive shaft 33 by alternating current generator 23, below is provided with scroll chuck 31 and air motor 22; Described helical teeth wheel disc 28 tops are provided with welding gun fixture 26, and welding gun fixture 26 and corresponding infrared inductor first 27 and the infrared inductor second 25 of being provided with on support 21; Described welding gun fixture 26 is installed fixing by left and right free degree adjusting nut 35 and easy on and off degree adjusting nut 34.
The utility model when making, the general frame of material (I-steel) welding robot that operating weight is heavier, support 21 adopts steel pipes (or I-steel) as supporting; The scroll chuck 31 that hoistable platform 30 arranges below can be realized adding of butt-welding fitting and hold; Scroll chuck 31, thrust bearing 29, helical teeth wheel disc 28 must be controlled axiality, guarantee the quality of weld seam; Electric cabinet 3 is controlled by PLC.
The utility model is when work, press start button, staff is placed on a weldment in upper scroll chuck 31, the three-jaw of the programme-control scroll chuck 31 in PLC is fixing firmly by workpiece, weldment ring flange and pipeline are realized to matched in clearance, make two weldments realize relative position and fix; By changing the relative position of welding gun fixture 26, make the head contact weld seam of welding gun, then by PLC to work order, welding gun welds, alternating current generator 23 drives helical teeth wheel disc 28 to drive welding gun to do turnover motion afterwards, when welding when circle just, the stop portion on helical teeth wheel disc 28 touches limit switch quits work alternating current generator 23; After short time, alternating current generator 23 reversions drive helical teeth wheel disc 28 to get back to original position, and alternating current generator 23 power-off immediately is also stopped the rotation, and enters armed state, so carry out the workpiece welding of next group.Because the workpiece material that needs are soldered is different, needed weld interval is also different, can regulate the speed of welding to reach the requirement of welding quality with frequency converter.
