[0050] Working principle: First, when the electric welder welds the metal sheet, the welding positioning fixture for the electric welder is used to position and clamp the metal sheet. After the metal sheet to be welded is placed on the support block 5, the output end of the driving motor 11 is connected to a wheel body through a transmission belt 13 and is connected to the corresponding pulley 12 for transmission. When the bidirectional screw 7 is driven to move, the driving motor 11 works through the transmission belt 13 to drive the corresponding pulley 12 to rotate. Through the transmission belt 13, the three groups of pulleys 12 will rotate synchronously. When the pulley 12 rotates, it will drive the bidirectional screw 7 to rotate. Since the bidirectional screw 7 is symmetrically provided with opposite threads, the two groups of thread blocks 9 can move in opposite directions. When the thread block 9 moves, it will drive the clamping block 8 to move. The clamping block 8 After the movement contacts the metal sheet, the metal sheet can be limited and clamped, thereby achieving the purpose of quickly positioning the welded metal sheet, so that the electric push rod 15 can push the connecting frame 16 to move, and when the connecting frame 16 is pushed, the driving plate 17 can push one side of the support block 5 to move, so that the support block 5 can make an arc movement around the driving shaft 3, and the angle of the metal sheet can be adjusted by adjusting the angle of the support block 5, so as to facilitate the support of the metal sheet for welding at different angles, and the intersection of the metal sheets can be processed by the electric welding machine, thereby improving the convenience of welding, and at the same time, the exhaust fan 20 can extract the air inside the flow slot 22 when it is working, and when the air flows inside the flow slot 22, the suction head 23 can The outside air is extracted, and then the smoke from welding the metal plate will flow into the flow groove 22 through the air inlet 24, and the particles carried by the air will enter the ventilation groove 26. The filter 27 can intercept and adsorb the smoke particles carried by the air, and the adsorption component will adsorb and intercept the carried particles, thereby achieving the purpose of air purification and avoiding affecting the surrounding environment. At the same time, the pumping pump 34 will work to extract the water source inside the heat storage box 32. After the extracted water source flows into the diversion pipe 35, it will flow into the heat absorption pipe 29 through the connector 36, and the purified air flows, the flow groove 22 is connected to the sealed box 21, and then the exhaust fan 20 will work to extract the air inside the sealed box 21. When welding metal sheets, welding smoke will be generated. After the smoke carries heat and follows the air into the flow groove 22, the filtered air will carry the heat and flow into the sealed box 21. Then, when the air carries the heat and flows through the heat absorbing tube 29, the water source can absorb the heat through the heat absorbing tube 29. The water source that absorbs the heat will flow through the inlet 37 and flow back into the heat storage box 32 for storage. The air drawn by the exhaust fan 20 will flow into the air collecting groove 30 through the output end of the exhaust fan 20, and then the air will flow into the diversion groove 38 through the connecting pipe 31 and the hose, and the air will flow to the surface of the metal sheet through the exhaust hole 39, so that the welded metal sheet can be cleaned.Improves the cleanliness of metal sheets.
