This welding system is realized the full-automatic operation of welding robot and workpiece transportation, and according to the classification of work station, the kind of workpiece, control program calls automatically; Avoid human factor the mistake of routine call to occur; Enhance productivity, reduce production costs, welding efficiency can double automatically.This welding system and method have realized full-automation, through the design of automatic material flow, accomplish a stream, and realize the beat-type production of whole production line and effectively reduced the handling stand-by period; After realizing the work pattern of a stream in the logistics, workpiece 8 rate flows increase, and are example with EMUs bogie frame of new generation, and the whole manufacturing cycle shortens 7 days.
Be that example specifies this welding method with the crossbeam welding process flow below:
Prior art middle cross beam welding process flow is:
The assembling of crossbeam--artificial welding beam--polishing of welding back weld seam---flaw detection.
Adopt the technological process after welding system of the present invention and the method to be:
(1) assembling of crossbeam, this operation is accomplished at artificial material stock platform 1 place.
(2) artificial backing welding is at first carried out in uneven place, workpiece 8 commissures, this operation is also accomplished at artificial material stock platform 1 place.
(3) operating personnel operate PLC master control system 7, start relative program, and travelling bogie 2 is transported to workpiece 8 at clamping device 4 places of welding robot 5 correspondences automatically; In the clamping device 4 confirm on the anchor clamps 9 no workpiece 8 near sense switch the time; Unclamp anchor clamps 9, the workpiece on the dolly 28 is clamped take off, behind the Rotate 180 degree; Workpiece 8 is transferred to the welding position of welding robot 5, and robot 8 welds by the welding procedure that sets in the PLC master control system 7.
(4) after welding was accomplished, clamping device 4 is the Rotate 180 degree again, and workpiece 8 is transferred to the position that dolly 2 can be got material, and dolly 2 takes off workpiece 8 from anchor clamps 9, and dolly 2 is transported to corresponding buffer table 6 places with workpiece 8 again.Again to robot 5 welding less than the position carry out artificial local repair welding.
(5) weld the afterwards polishing and the flaw detection of weld seam at last.
Though flow process is more complicated after adopting welding system of the present invention and method; But along with the dispersion of operation workload, the workload of each operation station is balance more, and crossbeam is formed realization mechanism hand and welded automatically; The manual work amount significantly reduces, and also can improve welding quality and production efficiency.
As stated, in conjunction with the given scheme content of accompanying drawing, can derive the similar techniques scheme.In every case be the content that does not break away from the utility model technical scheme, 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.
