Summary of the invention
The objective of the invention is in order to solve steel plate when welding, the increase of cost, man-hour, power consumption, consumptive material and the welding stress that produces owing to bevel, under the situation that guarantees fusing of weld seam two skirt walls and fusion, realize need not the narrow gap welding method of finished edge.
For achieving the above object, technical solution of the present invention provides a kind of narrow gap rotating the arc bonding machine, traveling dolly by the tape guide wheel, be displaced sideways platform, the oscilaltion transmission case, wire feeder, has the special ignition tip of certain drift angle at conducting rod rotating mechanism, conducting rod, and motor, compositions such as electric control system.Conducting rod is done positive and negative rotation under the drive of rotating mechanism, and rotary speed and rotating angular dimension are controlled, and the length of conducting rod can be selected according to the thickness of institute's welding steel, can go deep into the weld seam bottom to guarantee ignition tip; The special ignition tip of band bias angle theta is fixed on the conducting rod end, make and pass through conducting rod, the welding wire that stretches out behind the ignition tip forms the deflection of certain angle, therefore, when conducting rod rotates, it is the arc swing in the center of circle with the conducting rod center that the welding wire end just forms one, has enlarged welding wire end electric Arc Motion scope, weld seam two side steel plate walls all can directly be in melt preferably under the effect of arc heat and fuse into weld seam.
Be with the insulating ceramics cover on the cylindrical of described ignition tip.
Described bonding machine also comprises to be compiled the anglec of rotation of described ignition tip and corresponding welding conditions
The Programmable Logic Controller and the computer of journey and closed loop monitoring.
Described conducting rod rotation, the angle of its rotating is 180 ° to the maximum
Because when adopting narrow gap welding to connect, weld gap is fixed, therefore the traveling of welding tractor is except that adopting the laser guide, can also more directly adopt directive wheel mechanically to lead, being about to travelling wheel (non-driving wheel) is connected with directive wheel by the directive wheel support, because the width of directive wheel just in time sinks in the weld gap, thereby the traveling that guarantees dolly remains parallel with weld gap.
