Welding device

Abstract

The invention discloses a welding device. The welding device comprises an electricity connecting base and a plug part arranged on the left side of the electricity connecting base. The electricity connecting base is internally provided with a cavity. First sliding grooves are formed in the upper side and the lower side of the cavity. Each first sliding groove is internally provided with a spiral rod. The left side end of each spiral rod is connected with a motor. A first groove hole is formed in the inner wall of the right side of the cavity. First electricity connecting rods are arranged on the inner wall of the left side of the cavity. The cavity is internally provided with a sliding block of which the upper side and the lower side enter the first sliding grooves in the upper side and the lower side correspondingly and are matched and connected in a sliding mode. Sliding block bodies in the first sliding grooves are matched and connected with the spiral rods in a spiral whorl mode. The left side end surface of the sliding block is provided with first energizing holes opposite to the first electricity connecting rods. A circuit is arranged between the left side end surface of the sliding block and the first groove hole. An insertion cavity is formed in the wall body of the left side of the electricity connecting base. Second electricity connecting rods are arranged on the inner wall of the right side of the insertion cavity. According to the welding device, the structure is simple; operation is convenient and rapid; power supply connection can be automatically controlled; the insertion-connection stability and safety are high; an electric shock hazard caused by accidental touching is prevented; and the power supply requirement of existing electric welding machines is met.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding device. Background technique [0002] At present, welding machines are used more and more widely, and they rely on the power supply connection to work normally. Therefore, whether the power supply connection of the welding machine is stable and the safety of the power supply connection is the basis for determining whether the welding machine can work normally. The power supply line of the machine is thick and heavy, and the plug joint design of the welding machine is relatively simple and does not design any locking parts. The phenomenon of poor contact occurs, which has great disadvantages. At the same time, the existing socket setting mode matched with the plug connector is relatively simple, the protection ability is poor, and the protection device is lacking, so there is a large potential safety hazard.

[0002] At present, welding machines are used more and more widely, and they rely on the power supply connection to work normally. Therefore, whether the power supply connection of the welding machine is stable and the safety of the power supply connection is the basis for determining whether the welding machine can work normally. The power supply line of the machine is thick and heavy, and the plug joint design of the welding machine is relatively simple and does not design any locking parts. The phenomenon of poor contact occurs, which has great disadvantages. At the same time, the existing setting mode of the socket that matches the plug connector is relatively simple, the protection ability is poor, and there is a lack of protection devices, which has a large potential safety hazard.
