[0022] Working principle:

[0023] The welding gun is nested in the welding gun jacket 16, and the damping telescopic rod 13 is extended by pulling the handle 141 downward, and the welding gun is lowered to the welding position. Since the upper swing arm 11 and the lower swing arm 12 are of the same length and parallel to each other, the welding gun is always in a horizontal state during the downward pressing process, that is, the welding gun always maintains the original placement angle during the lowering process; when the handle 141 is pushed and pulled to raise and lower the swing plate 14 and the welding gun, the screw 133 cooperates with the rotating ring threads of the multiple rotating bidirectional dampers 132, so that the screw 133 generates a large damping force during the extension and retraction process. Therefore, after adjusting the position height of the welding gun, the damping force generated by the rotating bidirectional damper 132 on the screw 133 can stabilize the position of the welding gun;

[0024] When the placement angle of the welding gun needs to be adjusted, the welding gun jacket 16 is rotated to make the welding gun rotate along with the turntable 15. When the angle of the welding gun is adjusted, the locking screw 17 is rotated to lock the turntable 15, thereby locking the placement angle of the welding gun jacket 16;

[0025] When the position of the welding gun in the horizontal direction needs to be adjusted, the screw 8 is rotated by turning the handle 9, and the slide plate 4 slides along the linear slide rail 3. When the welding gun moves horizontally to an appropriate position, the locking screw 18 is rotated to lock the screw 8, thereby locking the position of the welding gun jacket 16 in the horizontal direction;

[0026] The welding gun clamping arm for filter element welding disclosed in the embodiment of the present invention clamps the welding gun through the welding gun jacket 16, and the damping telescopic rod 13 is extended by pulling the handle 141 downward, the welding gun is lowered to the welding position, and the damping force generated by the rotating two-way damper 132 on the screw 133 stabilizes the position of the welding gun. Since the upper swing arm 11 and the lower swing arm 12 are of the same length and parallel to each other, the welding gun is always in a horizontal state during the downward pressing process, that is, the welding gun always maintains the original placement angle during the descending process; the welding gun has a short descending stroke, the welding gun is quickly put into place, the structure is simple, and it is easy to use; and the horizontal position of the welding gun can be adjusted by rotating the handle 9, and the placement angle of the welding gun can be adjusted by rotating the welding gun jacket 16.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
