Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, and specifically relates to a cold welder. Background Art

[0002] A cold welder is an advanced welding equipment. Its working principle is that an arc is generated by the instantaneous discharge of a welding torch and contacts a metal workpiece. The high heat energy carried by the arc melts a special welding wire onto the welding part of the workpiece, so that the molten welding wire firmly fuses the welding parts of the workpiece to form a weld seam.

[0003] In the existing technology, the cold welder usually uses a hand-held welding torch for welding. When welding pipe-shaped workpieces, it is necessary to weld along the straight seam along the end face of the pipe. When the operator uses the hand-held welding torch for welding, it is impossible to ensure that the welding torch is always dragged in a straight line during welding, resulting in the deviation of the weld seam, uneven thickness distribution of the weld seam, and affecting the subsequent use of the workpiece.

[0004] In view of this, we propose a cold welder to solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cold welder to solve the problems raised in the above background art.

[0008] The fine-tuning mechanism includes a support. Inside the support, a first sliding seat is slidably arranged. Inside the first sliding seat, a second sliding seat is slidably connected. On the side end of the second sliding seat, a plate clamp is slidably connected. A welding torch is fixedly clamped by the plate clamp. On the top end of the support, a lifting cylinder is provided. The output end of the lifting cylinder passes through the top surface of the support and is slidably connected with the first sliding seat. On the top surface of the lifting cylinder, a wire clamp is provided.

[0009] Preferably, a long adjustment screw rod is vertically penetrated through the first sliding seat along the inner side of the front end of the first sliding seat away from the support. One end of the long adjustment screw rod located outside the top surface of the first sliding seat is connected with a knob.

One end of the short adjustment screw rod passes through the side wall of the front end of the second sliding seat and is connected with a knob. The second sliding seat is slidably connected with the plate clamp through the short screw rod.

[0011] Preferably, the short adjusting screw rod and the long adjusting screw rod are perpendicular to each other, and a clamping hole is provided at the center of one side of the plate clamp away from the second slide seat along the vertical axis direction perpendicular to the workbench, and a welding gun is fixed in the clamping hole.
