Novel welding device

Abstract

The invention discloses a novel welding device which comprises an electric welding machine and a power distribution portion. A first accommodating cavity is formed in the power distribution portion, asecond accommodating cavity is formed in the power distribution portion in the top of the first accommodating cavity, a sliding groove is formed in the top wall of the second accommodating cavity, aplacing groove is formed in the outer wall of the power distribution portion on the right side of the first accommodating cavity, a perforated hole is formed between the placing groove and the first accommodating cavity, a swivel pin shaft which extends up and down is arranged in the first accommodating cavity, the top of the swivel pin shaft penetrates through the wall body inside the power distribution portion and enters the second accommodating cavity and is spirally connected with the second accommodating cavity in a matched manner, a rotary tube is fixedly arranged on the swivel pin shaftin the first accommodating cavity, baffle blocks are correspondingly arranged on the upper and lower sides of the rotary tube, a cable winds the rotary tube between the upper and lower baffle blocks,a first tooth-shaped wheel is arranged on each of the tail and top portions of the swivel pin shaft in the second accommodating cavity, a spiral rod is arranged in the sliding groove, and the left end surface of the spiral rod is connected to a first motor. The welding device disclosed by the invention is simple in structure, convenient to operate and relatively high in safety, and the welding efficiency is improved.

Description

Technical field [0001] The invention relates to the field of welding technology, in particular to a new type of welding device. Background technique [0002] At present, electric welding machines are more and more widely used. However, because the power supply line of electric welding machines is relatively short, it often affects the movement of electric welding machines during welding. In the current situation, similar phenomena generally use one or more connections. The board is lengthened and connected to achieve the purpose of plugging and powering the welding machine. However, after multiple wiring boards are connected, the power supply line has a certain length, which is extremely inconvenient when retracted. At the same time, the power supply line is easily affected when it is scattered on the ground when not in use. Stepping on or scratching by a hard object causes damage to the insulation on the outside of the power supply line, which is very easy to induce electric sho...

Problems solved by technology

[0002] At present, electric welding machines are used more and more widely. However, due to the relatively short power supply line of electric welding machines, it often affects the movement of electric welding machines during welding. In the past, one or more wires are usually used to encounter similar phenomena. The board is lengthened and connected to achieve the purpose of plugging and powering the electric welding machine. However, after multiple terminal boards are connected, the power supply line has a certain length, which is extremely inconvenient when retracting. At the same time, the power supply line is scattered on the ground when it is not in use. The outer insulation of the power supply line is damaged due to trampling or scratching by hard objects, which can easily induce electric shock accidents, which has great disadvantages and is difficult to meet the existing needs
