Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an adjustable TIG welding gun bracket. Background Art

[0002] TIG welding refers to inert gas shielded arc welding using pure tungsten or activated tungsten (thoriated tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten) as a non-melting electrode. The arc between the tungsten electrode and the workpiece is used as a heat source to melt the added welding wire to form a weld. During the welding process, the tungsten electrode does not melt and only acts as an electrode.

[0003] When the TIG welding gun is working, the welding wire is fed through the wire wheel, the conductive nozzle conducts electricity, an arc is generated between the base material and the welding wire, the welding wire and the base material are melted, and the arc and the molten metal are protected by inert gas to perform welding. The existing welding method is that the welding gun is fixed with a bracket, and the worker holds the welding wire close to the welding gun by hand to perform welding. During the welding process, the position and angle of the welding wire cannot be positioned due to the hand-holding and it is easy to jitter, which affects the straightness of the weld and the welding quality cannot be guaranteed; and for welded parts with relatively complex structures and limited space and welded parts with right-angle structures, the welding gun will touch and interfere with the welded parts during the linear motion; for some workpieces with complex structures, such as welding corners of workpieces, the rotation angle of the welding gun needs to be continuously adjusted, which will lead to low production efficiency, so it is necessary to be able to quickly adjust the rotation angle of the welding gun.

[0023] according to Figure 1 and Figure 3 As shown, an adjustable TIG welding gun bracket includes two columns 1, and the columns 1 are connected by a guide rod 4. The guide rod 4 is multiple, and this structure is conducive to improving the stability of the up and down lifting mechanism, and two guide rods 4 are preferred;

[0024] An up-and-down lifting mechanism is horizontally slidably arranged on the guide rod 4, and the up-and-down lifting mechanism is connected to a mounting plate 10 at the bottom of the guide cylinder 9 to drive the guide cylinder 9 to lift up and down. A connecting rod 11 with an adjustable rotation angle is rotatably arranged in the guide cylinder 9, and a clamping part 13 for clamping a welding gun 12 is connected to the free end of the connecting rod 11. It is further defined that a plurality of up-and-down lifting mechanisms are horizontally slidably arranged on the guide rod 4, and the welding gun 12 is rotated in the Y-axis direction by rotating the connecting rod 11 to adjust the rotation angle.

The slider 7 is installed on one side of the lifting block 2, and the other side of the lifting block 2 is connected to the mounting plate 10. The driving mechanism 3 is preferably a pneumatic rod or an electric push rod.

[0027] The back side of the L-shaped plate 5 is connected to the sliding block 8, and a moving hole 29 cooperating with the guide rod 4 is provided in the sliding block 8 to enable the sliding block 8 to move axially on the guide rod 4. Through this structure, the up and down lifting mechanism can be adjusted in the horizontal direction to realize horizontal linear welding of the welding gun 12.
