Description

Technical Field

[0001] The utility model relates to the technical field of electric welding machines, in particular to an electric welding machine for mechanical processing. Background Art

[0002] The electric welding machine uses the high-temperature arc generated when the positive and negative poles are short-circuited for an instant to melt the solder on the welding rod and the material to be welded, thereby combining the contacted objects. It is widely used in mechanical workpiece processing.

[0003] A mechanical processing electric welding machine disclosed in publication number CN218612183U includes an electric welding machine body, and two output lines are connected to the back of the electric welding machine body; positioning mechanisms are arranged on both sides of the winding disk; the positioning mechanism includes a positioning ring, a rotating groove, two fixed grooves, a rotating rod, two torsion springs, a limit block, a pull block, a slider and a slide groove, the two ends of the rotating rod are rotatably connected to the inner cavity of the two fixed grooves, the two torsion springs are arranged at the two ends of the rotating rod, the pull block is fixedly connected to one end of the limit block, and the slider is slidably connected to the inner cavity of the slide groove.

[0004] The above document utilizes a setting method in which a winding reel and a positioning mechanism are coordinated. The winding reel facilitates the storage of the output line, and the torsion spring enables the limit block to stably press and limit the output line in the positioning ring, thereby facilitating the fixation of the output line. By moving the pull block and clamping the limit block with the slider, the limit block does not affect the sliding of the output line, thereby improving the stability of the output line.

[0005] However, when the electric welding machine is in use, the heat generated by the internal electrical appliances is very large. If used for a long time, the internal components of the electric welding machine will be damaged due to the high temperature. It is difficult to meet the heat dissipation requirements by relying solely on the heat dissipation of the electric welding machine's own radiator. At the same time, in the above-mentioned document, the output cable is reeled in by means of a reel, and when the reel rotates, the two ends of the cable wound thereon are reeled in. Therefore, when the reel unwinds a long cable, the corresponding cable will become loose on the other side, which is very inconvenient to use. In view of the above problems, an innovative design is carried out on the basis of an original electric welding machine for mechanical processing. Utility Model Content
