Welding device

Abstract

The invention discloses a welding device. The welding device comprises a supporting post, a cross beam and a plug head, the cross beam is fixed at the top of the supporting post and extends leftwards, the plug head is in fit joint with the cross beam, a plugging groove is formed in the left end face of the supporting post, a second plugging piece is arranged on the inner right wall of the plugging groove, a sliding groove is formed in the bottom end face of a left extension segment of the cross beam, a first crew rod extending leftwards and rightwards is arranged in the sliding groove, a push block is connected to the first screw rod in a threaded manner, a first force transfer cavity is formed in the position, on the left side of the sliding groove, of the cross beam, a first rotating shaft extending leftwards and rightwards is arranged in the second force transfer cavity, and the right end of the first rotating shaft is connected with a driver. The welding device is simple in structure, high in safety and working efficiency and capable of achieving automatic control of plugging and power supply connection and controlling a shielding plate to extend out automatically.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a welding device. Background technique [0002] At present, electric welding machines are used more and more widely, and they rely on plug-in power supply to work normally. Therefore, whether the electric welding machine is plugged in stably and whether the power supply is safe is the basis for determining whether the electric welding machine can work normally. The plug-in power supply generally relies on manual plug-in. However, due to the high voltage required by the electric welding machine, the stability of manual plug-in is poor, and arcs are likely to be generated during the plug-in process. The generation of arcs is likely to cause electric shock to users. The user has a certain potential danger, which will cause safety accidents and cause casualties. Moreover, there is no protection device when the power supply is plugged in, and it is easy to loosen or cause damage to th...

[0002] At present, electric welding machines are used more and more widely, and they rely on plug-in power supply to work normally. Therefore, whether the electric welding machine is plugged in stably and whether the power supply is safe is the basis for determining whether the electric welding machine can work normally. The plug-in power supply generally relies on manual plug-in. However, due to the high voltage required by the electric welding machine, the stability of manual plug-in is poor, and arcs are likely to be generated during the plug-in process. The generation of arcs is likely to cause electric shock to users. The user has a certain potential danger, which will cause safety accidents and cause casualties. Moreover, there is no protection device when the power supply is plugged in, and it is easy to loosen or cause damage to the plug connector due to accidental touch by personnel. There are major disadvantages and need to be improved.
