Traveling device of automatic welding tractor

Abstract

The invention provides a traveling device of an automatic welding tractor. The traveling device comprises an automatic welding tractor body with magnetic bases at two ends inside, guide arms are installed at two ends of the outer side of the tractor body, the other ends of the guide arms extend to the right side of the tractor body and are provided with straight rods, a guide rod is installed between the two straight rods, and a plurality of guide wheels and magnetic blocks are installed on the lower surfaces of the two ends of the guide rod at intervals through bolts; and traveling wheels are installed on the two sides, close to the guide arms, of the tractor body, a traveling driving mechanism is installed in the middle of the tractor body, the traveling driving mechanism drives gears to conduct transmission through a motor, and therefore, a plurality of driving wheels and the traveling wheels installed in the middle of the tractor body are driven to travel, and the automatic traveling function of the welding tractor is achieved. The attraction force of the magnetic bases to the upper surface of a workpiece and the attraction force of the magnetic blocks to the side face of the workpiece jointly guarantee that the automatic welding tractor stably runs on the surface of the workpiece along a straight line all the time and cannot fall or turn over, all welding seams at the end of the workpiece are welded at a time, the welding quality is good, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of welding manufacturing technology, in particular to a running device of an automatic welding trolley. Background technique [0002] The existing automatic welding trolley cannot weld a section of the weld seam on the plane at both ends of the workpiece. It is necessary to manually add an auxiliary plate to weld and lengthen the two ends of the workpiece. A section of welding seam is determined by the structure of the automatic welding trolley, which cannot be overcome at present. This welding method increases labor costs and material costs, and the efficiency is extremely low. [0003] The existing automatic welding trolley cannot always walk along a straight line during the working process, and often deviates; during the welding process, since the guide wheel of the automatic welding trolley only leans against the side of the workpiece, there is no external force to correct the deviation of the trolley , It is nec...

Problems solved by technology

[0002] The existing automatic welding trolley cannot weld a section of the weld seam on the plane at both ends of the workpiece. It is necessary to manually add an auxiliary plate to weld and lengthen the two ends of the workpiece. A section of welding seam is determined by the structure of the automatic welding trolley, which cannot be overcome at present. This welding method increases labor costs and material costs, and the efficiency is extremely low

[0003] The existing automatic welding trolley cannot always walk along a straight line during the working process, and often deviates; during the welding process, since the guide wheel of the automatic welding trolley only leans against the side of the workpiece, there is no external force to correct the deviation of the trolley , it is necessary to stop the welding work, after manual calibration, and then restart the equipment again, the weld will be disconnected, which will affect the welding quality and work efficiency

[0004] In addition, because the welding seam will generate high temperature during the welding process, the rubber wheels of the subsequent automatic welding trolley will burn out and cannot work normally. Therefore, it is impossible to use multiple automatic welding trolleys for welding at the same time, which is not conducive to the improvement of work efficiency.
