The specific embodiment
By Fig. 1 to Fig. 5 illustrate, a kind of large-diameter pipeline automatic soldering device, is mainly comprised of parts such as car body 1, support arm 2, working arm 3, welding head 4 and connecting axles 5.Car body 1 below is provided with two groups of road wheels 11, can make whole welder at axial quick, the easy motion of pipeline 6.Three support arms 2 are bolted on connecting axle 5, along pipeline, within 6 one weeks, are uniformly distributed, and by the supporting role of three support arms 2, in welding process, can make whole welder hold out against on pipeline 6 inwalls.Two working arms 3 are along pipeline 6 radial distribution, and its one end is arranged on connecting axle 5, and the other end is connected with welding head 4.In welding process, under programme-control, the welding gun 49 on two heads can be aimed at weld seam and complete automatic welding.
The mode that support arm adopts brace summer 21 to be connected with telescopic cylinder 22, can adjust in real time according to the diameter of workpiece to be welded.
The mode that working arm also adopts work beam 31 to be connected with telescopic cylinder 32, also can adjust in real time according to the diameter of work to be welded.
43 orientations of track of telescopic cylinder 32 both sides, two tracks 43 overlap separately and have spring 44 through connecting plate 46, two siding track 43 lower ends respectively, and connecting plate 46 upper ends are connected with ring flange 45 with telescopic cylinder 32 outputs.Like this when cylinder 32 extends, can holddown spring 44, the pressure of spring 44 passes to welding pinch roller 48 by the pressing plate 47 being fixed together with welding head 4 of spring 44 lower ends, and pinch roller 48 is pressed on tube wall 6; When cylinder 32 is retracted, cylinder 32 band dynamic pressure plates 47, drive pinch roller 48 can leave fast tube wall 6 immediately.
Working arm 3 can adopt two schemes with being connected of connecting axle 5, a kind of working arm 3 is fixedly connected with mode by key or other and is directly connected with connecting axle, in welding process, by motor 7, drives connecting axles to rotate (being that motor is contained on connecting axle), thereby drive welding head 4 rotations, weld.Another scheme is that two welding heads (are equipped with motor 71,72 separately on Isosorbide-5-Nitrae 2, working arm puts on connecting axle by axle sleeve, in welding process, and two welding heads 41,42 rotations, drive welded grider separately to rotate around connecting axle, and connecting axle itself do not rotate.
At the scene in welding process, first by the length adjustment of support arm 2 and working arm 3 to being less than pipe diameter, can make whole device axially enter in pipeline along pipeline 6, road wheel 11 can be automatically also can manual movement, drive whole welder to move to position to be welded.Then support arm 2 extends automatically, under the effect of three support arms, whole welder is held out against on pipeline 6 inwalls, and road wheel 11 is now unsettled.Two working arms 3 extend automatically, finally make the welding gun 49 on welding head 4 hold out against in position to be welded, then by program automatic or manual, adjust the welding gun 49 swing mechanism 410He angle swing mechanisms 411 on welding head 4, make welding gun 49 adjust to optimum position, then start to weld along inner-walls of duct.
Wherein on support arm 2 and working arm 3, cylinder is all installed, length can be adjusted automatically according to actual conditions, if the caliber that welding scene requires has larger difference, exceed Telescopic-cylinder scope, can reach field requirement by changing support arm 2 or working arm 3 bodies.
In addition, in order to raise the efficiency, can increase according to actual conditions the quantity of welding head.
