Technical field
The utility model relates to a kind of welder, relates in particular to a kind of straight weld from the motion tracking submerged arc welding machine.
Background technology
When the steel tube factory produces steel pipes with straight automatically at present, need welding gun be adjusted to certain distance range and weld, adopt mechanically tracking mechanism controls welding gun to follow the tracks of welding automatically usually.The existing mechanical follower is on the trace component of mechanically tracking mechanism, to install welding gun; The trace component move left and right; And contact respectively with the contact point that is positioned at the straight steel pipe two ends; The mode that contact point normally adopts copper sheet and copper sheet to be in contact with one another realizes being communicated with and drives the servomotor motion, the motion automatically up and down of servomotor control welding gun, thus realize the purpose that welding gun is followed the tracks of welding automatically.Can there be following problem in the mechanically tracking mechanism of this structure: because contact point is the mode that adopts copper sheet and copper sheet to be in contact with one another, long operational time is out-of-date, and contact action is frequent; The copper sheet easy deformation of contact point, and cause the contact resistance of contact point to increase, phenomenons such as loose contact appear; Therefore cause the welding gun tracking sensitivity to reduce; Directly influence welding quality, and sensitivity neither be very high normal practical the time, safeguards very inconvenient.
The utility model content
The purpose of the utility model is exactly to provide straight weld from the motion tracking submerged arc welding machine for fear of above prior art deficiency.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of straight weld is from the motion tracking submerged arc welding machine; Comprise lathe, welding gun and trace component; Said trace component comprises that slide block is followed the tracks of on mechanical arm, relay, servomotor, screw mandrel transmission, left sensor, right sensor, a left side and slide block is followed the tracks of on the right side; Said mechanical arm is arranged on said lathe top, and slide block is followed the tracks of on a said left side, the both sides that slide block lays respectively at said mechanical arm are followed the tracks of on the right side, and said left sensor, right sensor lay respectively at the both sides of said lathe; And said left sensor is corresponding with tracking slide position, a said left side; Said right sensor is corresponding with the said right slide position of following the tracks of, and the output of said left sensor, right sensor all is connected with said relay, and said relay is connected with said servomotor; Said servomotor is connected with said screw mandrel transmission, and said welding gun is connected the below of said mechanical arm through said screw mandrel transmission.
Further, said trace component also comprises the tracking profiling wheel, and said tracking profiling wheel is fixedly connected on the below of said mechanical arm.
Further, said mechanical arm both sides are respectively equipped with groove, and slide block is followed the tracks of on a said left side, the right slide block of following the tracks of is arranged in the said groove.
The beneficial effect of the utility model is that the utility model straight weld is simple in structure, easy to maintenance from the motion tracking submerged arc welding machine, adopts sensor to replace traditional follower contact point copper sheet and the contacted mode of copper sheet; Sensitivity is greatly improved, and especially aspect solder yield, improves a lot, and has increased the output that improves order of classes or grades at school weld interval; The welding quality of steel pipe is also guaranteed reliably; Be applicable to that diameter is the big steel pipes with straight of any model in 508 ~ 1440mm scope, efficiently solving steel pipe, directly to spend the overproof and crooked welding that brings inhomogeneous, phenomenons such as sky weldering; And antijamming capability is strong, and near automation equipment is not produced interference.
Description of drawings
