s1: a worker brings two metal plates to be welded close to and in contact with each other, places a rail of a welding machine on one of the metal plates to be welded, places a vehicle body 1 on the rail, and controls the vehicle body 1 to move along the rail through a controller, so that the vehicle body 1 drives a welding head 3 to be positioned above the metal plates to be welded, and at the moment, a baffle 331 drives a sponge 332 below to wipe the welding position of the metal plates;
s2: along with the movement of the vehicle body 1, the grinding wheel 34 is in contact with the metal plates, so that the grinding wheel 34 grinds the metal plates until the brush plate 4 is positioned on the metal plates, the controller controls the servo motor 44 to drive the brush plate 4 to clean metal particles between the two metal plates, and at the moment, the controller controls the air suction pump 11 to operate, so that the suction pipe 12 sucks residual oxidized metal particles on the surfaces to be welded of the metal plates;
s3: when the blanking pipe 321 and the contact tip 31 are located at the upper end of the polished metal plate, a worker controls the metal plate welding machine to stop through the controller, flux is added into the hopper 32, after the flux is added, the controller controls the metal plate welding machine to continue to operate, the flux in the hopper 32 is accumulated at the upper end of the polished metal plate and buries the welding wire 21 exposed out of the contact tip 31, the controller controls the contact tip 31 to conduct electricity, the welding wire 21 is melted with the flux around the welding wire 21, and therefore the two metal plates are welded.
The specific working process is as follows:
an operator controls the vehicle body 1 to move through the controller, so that the vehicle body 1 drives the grinding wheel 34 to move to the upper ends of the positions to be welded of the two metal plates through the support 33, the grinding wheel 34 is in contact with the metal plates, at the moment, the controller controls the driving motor 35 to drive the grinding wheel 34 to rotate, the controller controls the air suction pump 11 to operate, the air suction pump 11 sucks oxidation particles on the surfaces of the plates after the grinding wheel 34 is ground through the suction pipe 12, the grinding wheel 34 continuously grinds the metal plates along with the forward movement of the vehicle body 1 until the discharging pipe 321 and the conductive nozzle 31 are positioned at the upper ends of the positions to be ground of the metal plates, at the moment, the welding wire 21 in the conductive nozzle 31 is in contact with the ground metal plates, the operator controls the metal plate welding machine to stop through the controller, and adds a welding flux into the hopper 32, after the addition of the welding flux is completed, the controller controls the vehicle body 1 to continue to operate, the grinding wheel 34 continues to grind, at the moment, the welding flux in the hopper 32 is accumulated at the upper end of the ground metal plates, so that the welding flux buries the welding wire 21 exposed out of the contact tip 31, the contact tip 31 is controlled by the controller to conduct electricity, the welding wire 21 is melted with the welding flux around the welding wire 21, the two metal plates are welded, the welding head 3 pulls the welding wire disc 2 to rotate through the welding wire 21 along with the movement of the vehicle body 1, the welding wire 21 on the welding wire disc 2 is continuously conveyed to the contact tip 31, and therefore the metal plates are welded; along with polish wheel 34 polishes two blocks of waiting to weld metal sheet material that are close to each other, make to polish and drop the oxidation granule and drop to the gap between two metal sheet materials, along with polish wheel 34 continues to polish forward, make polish wheel 34 drive brush board 4 forward movement at rear through support 33, make brush board 4 at the in-process that removes, brush hair 41 of brush board 4 bottom can get into the gap between two metal sheet materials, make brush hair 41 promote the oxidation metal granule that drops to the metal sheet gap constantly move forward, when brush hair 41 removed to the other end of two metal sheet materials, brush hair 41 promoted the oxidation metal granule in two metal sheet gaps and dropped from metal sheet material's the other end.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
