The specific embodiment
Referring to Fig. 1, Fig. 2; The outer horizontal position welding of headwall of the utility model and end carriage is stitched automatic fillet welding in the overhead position welding system and is comprised welding position converting means 1, weld tracker 2 and welding operating control device 3, and welding position converting means 1 comprises complete machine fast moving device 10, gantry mobile device 11 and tracking transfer 12 at a slow speed.The complete machine fast moving motor 102 of complete machine fast moving device 10 rotatablely moves and drives wheel after the transmission through worm-gear speed reducer 103 and sprocket wheel chain secondary 104; Automatically fillet welding in the overhead position welding system complete machine carries out fast moving, and stop motion immediately after arriving desired location; Gantry rotatablely moving of gantry mobile motor 112 of mobile device 11 at a slow speed rotates through driving leading screw 114 after bevel gear 113 transmissions; Gantry 13 that the leading screw of rotation drives automatic fillet welding in the overhead position welding system moves to the other end from an end of complete machine slowly, stop motion immediately after gantry 13 arrives the position of setting; The rotatablely moving of worm-drive motor 121 of following the tracks of transfer 12 is rotated motion through driving weld tracker 2 after the transmission of worm-gears 122 around the Z axle, when the anglec of rotation reaches 180 °, stops operating immediately.Complete machine fast moving device 10, gantry is mobile device 11 and to follow the tracks of transfer 12 all be by touch programmable terminal, programmable controller, Frequency Converter Control operation at a slow speed.When following the tracks of transfer 12 operations, at first weld tracker 2 is risen to the top, be rotated around the Z axle again by touch programmable terminal, programmable controller controls lifting device 14.Through complete machine fast moving device 10, gantry mobile device 11 and follow the tracks of the routing motion of transfer 12 3 parts at a slow speed, the welding position converting means 1 of the utility model can carry out the conversion of welding position at C70A open-top car two ends easily according to operating personnel's order.
Welding operating control device 3 is accurately rotated by coordinate and the speed set by touch programmable terminal, programmable controller, AC servo driver control AC servomotor 31.The rotation of AC servomotor 31 drives planker 33 and goes up each parts of installing and carry out accurate rectilinear motion along X-direction together after the transmission of rack-and-pinion 32.When carrying out weld job, welding beginning when the welding arcing point coordinate of X axial coordinate and setting is identical; When the welding of X axial coordinate and setting receive the acnode coordinate when identical welding finish.
Referring to Fig. 3, weld tracker 2 adopts the mechanical type tracking means, and the mechanical type tracking means links to each other with mounting bracket 21 through rotating shaft 20 and weld tracker 2 20 rotations around the shaft.When making progress slip angle adjustable plate 22, weld tracker 2 increases with the initial angle of horizontal plane; When downward slip angle adjustable plate 22, weld tracker 2 reduces with the initial angle of horizontal plane.Can control the elemental height and initial outreach of tracking wheel 27 through the adjusting weld tracker 2 and the size of the initial angle of horizontal plane.Follow the tracks of cylinder 23 and link to each other, stretch out together when following the tracks of line slideway slide block 25, the follower head 26 that can drive follower head supporting plate 24 simultaneously when cylinder 23 stretches out and upward install with follower head supporting plate 24.Follower head 26 links to each other with follower head supporting plate 24 through line slideway slide block 25, and tracking wheel 27, welding gun 28, welding gun adjuster 29 are installed on follower head 26.First spring 210 is installed between follower head 26 and the follower head supporting plate 24, and second spring 211 is connected and installed support 21 and follows the tracks of cylinder 23.
In welding process, at first utilize complete machine fast moving device 10 operations of welding position converting means 1 to arrive near the set point of workpiece.Gantry that utilizes welding position converting means 1 then mobile device 11 at a slow speed makes weld tracker 2 accurately run to the weld seam setpoint distance place apart from the elevation angle.Follower head 26, tracking wheel 27 and welding gun 28 can stretch out together when tracking cylinder 23 stretched out.Owing to follow the tracks of cylinder 23 outreach greater than the distance between tracking wheel 27 and the workpiece, the vertical surface that tracking wheel 27 has been run into workpiece when tracking cylinder 23 does not also stretch out fully.Because tracking wheel 27 receives the active force of workpiece, weld tracker 2 20 rotates counterclockwise around the shaft, and second spring 211 stretches and makes tracking wheel 27 be adjacent to surface of the work.Following the tracks of cylinder 23 promotion tracking wheels 27 continues to slide along surface of the work; When tracking wheel 27 outer rims arrive at elevation angle position while welding; Elevation angle weld seam radially applies reaction force to tracking wheel 27 along tracking wheel, and this reaction force affacts on the follower head 26 through tracking wheel 27 and makes 210 precommpression of first spring.When the automatic soldering device of the utility model welds when moving along X-direction, tracking wheel 27 is close to surface of the work all the time and is propped up weld seam under the effect of first spring 210 and second spring 211.When weld seam when Y axle or Z-direction have skew; First spring 210 carries out corresponding compression automatically or loosens; Make follower head 26 withdrawals or ejection, thereby in time compensated the side-play amount of Y axle or Z-direction, guaranteed that the welding wire front end of welding gun 28 and weld seam center remain constant distance.
