Improved welding device

Abstract

The invention discloses an improved welding device which comprises a base body, a photovoltaic portion fixedly installed at the end face of the top of the base body, and a plug. The base body is composed of a bearing portion and a sliding and pushing portion; a push groove is formed in the bottom end face of the sliding and pushing portion and internally provided with a first screw rod extending left and right; the right end of the first screw rod is connected with a first motor; the push groove is internally provided with a push block connected with the first screw rod in a threaded fit mode;a first cavity is formed in the push block; a locking groove with the bottom penetrating through the bottom end face of the push block is formed in the position, on the right side of the first cavity, of the interior of the push block; the right end of the first cavity communicates with the upper portion of the left side of the locking groove; a slotted hole is formed in the position, at the bottom of the first cavity, of the interior of the bottom end face of the push block; and a first rotary connection shaft extending up and down is arranged inside the first cavity. The improved welding device is simple in structure, and rapid and convenient to operate, can automatically control power supply insertion and connection, prevents the electric shock accident caused by unstable manual insertion and connection, improves the power supply insertion and connection safety, saves energy and is environmentally friendly due to power generation and power supply of solar energy, saves electric power resources and reduces the use cost.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to an improved 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 certain potential dangers, which will cause safety accidents, and there are relatively large safety hazards. There are also some electric welding equipment that can be automatically plugged in, but...

[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 certain potential dangers, which will cause safety accidents, and there are relatively large safety hazards. There are also some electric welding equipment that can be automatically plugged in, but they need to be powered by the mains to control the propulsion equipment when plugging in. The operation of automatic plugging operation causes waste of power resources and increases the cost of use, which cannot meet the existing needs
