Description
Technical field
The utility model relates to the automatic welding technique field, relates in particular to a kind of Lincoln weld welder that is applicable to the circular girth joint of level.
Technical background
The welding process of submerged-arc welding is the same substantially with the process of SMAW, just the coating on the welding wire has been changed over granular solder flux, earlier the solder flux spreading in welded joints, the electric arc during welding between welding wire and the weldment is flowed or blow over and cover completely fully under welding flux layer and is burnt before the welding.Solder flux near arc region is melted under the effect of arc heat, and the solder flux of graininess solder flux, fusing makes it electric arc and tight the surrounding of molten pool metal and isolate from outer air.Welding wire constantly is fed to arc region, and moves along welding direction, and electric arc also moves thereupon, continues fusing weldment and solder flux, forms a large amount of liquid metals and liquid flux.After cooling, weld seam and welding slag have just been formed.Because electric arc is embedded in below the solder flux, so claim submerged-arc welding.Welding wire in the said process is sent to welding wire and is moved forward two kinds of operations when finishing automatically by welding machine along weld seam, Lincoln weld that Here it is.
The advantage of Lincoln weld has: 1) production efficiency height; The comparable manual welding of the productivity ratio of Lincoln weld improves 5～10 times, because do not have coating on the welding wire during Lincoln weld, welding wire can be very long, and can send to continuously and need not to change welding rod.So can adopt the welding of big electric current, the electric arc heat is big, wire melting is fast, and fusion penetration is also big, and speed of welding is than fast many of manual welding; 2) protecting of welding flux layer butt welded seam metal is so weldquality is good; 3) save steel and electric energy; Steel plate thickness is generally below 30 millimeters the time, but the Lincoln weld square groove, and this has just saved steel greatly, and because electric arc is being protected by solder flux, the heat of electric arc is fully used, thereby has saved electric energy; 4) improve working conditions, except that reducing the amount of labour, owing to can't see arc light during weldering automatically, the gas flow that sends in the welding process is few, this to protection welder's eyes and healthy be very useful.
But because the submerged arc welding machine head walking dolly that present Lincoln weld is adopted can only be finished craspedodrome at horizontal level, so Lincoln weld is applicable to long straight weld of welding or large diameter girth joint usually, resemble spherical tank manhole flange and the circular weld seam of the level of extremely middle plate butt weld and so on and run into, just can only adopt the manual arc welding.Therefore, be necessary technical scheme of the prior art to be done further improvement, to remedy the deficiency in the existing Lincoln weld technology at the problems referred to above for this reason
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, can make the submerged-arc welding head can rotate the circular girth joint Lincoln weld of the level device of welding automatically along horizontal circular direction.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: the circular girth joint Lincoln weld of level device, include the Lincoln weld machine head, it is characterized in that: it includes column, base, transmission device, motor, the Lincoln weld machine head is connected the upper end of column, column is installed on the base by bearing, and motor is installed on the base, and motor is by the rotation of actuator drives column.
Described transmission device is the bevel gear of pair of meshing, and the bottom of column is connected with bevel gear wheel, and the turning cylinder head end of motor is connected with bevel pinion, and motor rotates together by the big or small bevel gear driving column drive Lincoln weld machine head of engagement.
Described motor and controller are done and are electrically connected, and controller is controlled turning to and rotating speed of motor; Controller is installed in the control cabinet, and control cabinet is provided with the tuning button and the speed governing button is regulated turning to of motor and rotating speed respectively.
Described motor is the reducing motor that disposes decelerator.
Be connected with holddown groove on the described base, holddown groove is a hollow structure, and motor rotation axis, column penetrate inherent its inner cooperation of holddown groove; Be provided with bearing between column and holddown groove, but near the ring of embracing that load-bearing also is housed on the column of bearing.
The utility model possesses following beneficial effect:
1) uses the motor-driven column to drive the rotation of submerged-arc welding head, replace the walking dolly of common submerged arc welding machine craspedodrome, satisfy the automatic welder(welding machine) head walking needs of the circular weld seam of level, reach the technological requirement of automatic rotation welding;
2) the tuning button on the control cabinet can change the rotation direction of the polarity of direct current generator with the adjusting motor, thereby can regulate the direction of travel of head, and the voltage at the then adjustable joint motor of speed governing button two ends is with the adjusting rotating speed of motor, and then the rotary speed of regulating head; Control is simple, and is easy to operate;
3) transmission device adopts the bevel gear of pair of meshing to cooperate and forms the bevel gear pair transmission and since the stable transmission characteristics of bevel gear make head stable and walking evenly.
