Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a novel desktop cold welding machine. Background Art

[0002] Cold welding machine is a kind of welding equipment. It uses the high heat energy generated by the instantaneous discharge of the charging capacitor to melt the special welding wire onto the damaged part of the workpiece and firmly weld it with the original base material. Its working principle is that through the instantaneous discharge of micro-electricity, the contact part between the electrode material and the workpiece is instantly heated to an extremely high temperature, and the molten metal in the plasma state is transferred to the surface of the workpiece in a metallurgical way;

[0003] When a handheld welding gun is used to weld a workpiece, the handheld welding gun often needs to be moved along the welding position of the workpiece for welding. At this time, the handheld welding gun is in a suspended posture, which can easily cause shaking during welding. The instability of the handheld welding gun will cause discontinuity in the welding trajectory, thereby affecting the welding quality. Therefore, during the welding process, the welding wire and the workpiece need to contact and melt accurately. If the welding gun does not move steadily, it may cause uneven welding points, and even cause problems such as cold welding and leaking welding. Utility Model Content

The mounting rings 11 located on both sides of the fixing seat 14 are provided with mounting grooves 16, and a fixing shaft 17 is fixedly installed at the center position of the inner side of the mounting groove 16. Metal springs 18 are fixedly installed in the mounting grooves 16 located on both sides of the fixing shaft 17.

With the arrangement of the fixing shaft 17, the rotation installation of the support rod 12 can be realized, and the arrangement of the two metal springs 18 can ensure the self-reset of the support rod 12.

[0023] like Figure 3-Figure 4As shown, a connecting block 15 is fixedly installed on the upper end of the support rod 12, a screw groove 21 is opened at the lower end of the support rod 12, and a rotating groove 22 is opened on the support rod 12 inside the screw groove 21.
