Integrated weld position detection device based on binaural effect

An integrated weld position detection device based on a binaural effect, comprising a microphone, a microphone holder, a megaphone, a conductive rod, and a current contact nozzle, wherein the microphone holder is provided with a first through hole in the center;

• the first through hole allows the conductive rod to pass through and is fixedly connected to the conductive rod;
• the current contact nozzle is fixedly connected to the conductive rod;
• the microphone holder is internally provided with two accommodating cavities;
• the two accommodating cavities are symmetrically distributed on left and right sides of the microphone holder;
• two microphones are respectively disposed inside the two accommodating cavities, and the microphones are in electrical or communication connection with an information processing structure;
• the conductive rod is connected with a welding gun;
• the current contact nozzle is connected with a welding wire;
• the conductive rod has a gas guiding cavity, and a first end of the gas guiding cavity communicates with a gas outlet of the welding gun;
• a side wall of the conductive rod is provided with a second through hole;
• a first end of the current contact nozzle extends into the first through hole and is fixedly connected to the conductive rod;
• a second end of the current contact nozzle extends out of the first through hole, and the second end of the current contact nozzle has a welding wire socket;
• the megaphone is provided with a third through hole for accommodating the current contact nozzle;
• the megaphone is fixed on the microphone holder;
• the megaphone is provided with at least two sound transmission channels;
• first ends of the two sound transmission channels communicate with the two accommodating cavities respectively;
• second ends of the two sound transmission channels extend to a surface of the megaphone and locate on left and right sides of the third through hole;
• a protective gas in the welding gun can pass through the gas guiding cavity, the second through hole, the first through hole, and the third through hole in sequence and flow out of the megaphone.
