The welding bracket is not fixedly arranged on a copper nozzle of the welding gun, so that the coaxiality of the welding gun can be prevented from being influenced by hard connection between the copper nozzle of the welding gun and the welding bracket; besides, the straight opening for the copper nozzle of the welding gun to penetrate through is formed in the front-back adjusting sliding block, so that the copper nozzle can avoid the front-back adjusting sliding block and is covered and protected by three faces of the front-back adjusting sliding block, the situation that the robot collides and damages the periphery of the copper nozzle of the welding gun is prevented, and therefore welding gun interference and welding coaxial damage caused by robot collision can be reduced; meanwhile, due to the fact that the front-and-back adjusting sliding block can be adjusted in a three-dimensional mode through the up-and-down adjusting plate, the left-and-right adjusting block and the front-and-back adjusting sliding rail to meet the position adjusting requirements of the welding wires in different occasions, the welding accessibility of the welding gun is improved, and the laser welding quality is guaranteed.

Description

Technical Field

[0001] The utility model relates to the field of laser welding, in particular to a filler wire bracket used for laser welding. Background Art

[0002] In current laser welding structures, the wire feeding bracket is typically clamped to the outside of the copper nozzle of the laser welding gun head, as exemplified by a welding device with patent publication number 220372435 U and a laser welding device with a filler wire with patent publication number CN214291475 U. In practice, the applicant has discovered that these structures present the following problems:

[0003] 1. Since the welding bracket is clamped to the outside of the copper nozzle of the laser welding gun head, it is easy to cause the welding gun and the copper nozzle to be out of axial alignment. Once the axes are out of axial alignment, it will increase the difficulty of adjustment and correction during laser welding and affect the welding effect.

[0004] Second, the welding bracket occupies a large space, and the wire feed nozzle at the lower end of the welding bracket can only be rotated and adjusted up and down through the bracket, but cannot be adjusted forward and backward. This increases the probability of welding gun interference and affects the accessibility of welding gun welding to a certain extent, thereby affecting the welding quality. Summary of the Invention

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a more compact structure that can reduce welding gun interference and robot collision damage to the coaxial laser wire welding bracket, which helps to improve the accessibility of welding gun welding and improve the quality of laser welding.

[0006] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

[0007] A laser wire-filling welding bracket comprises a bracket, a gun head mounting plate, an upper and lower adjustment plate, a left and right adjustment block, a front and rear adjustment slide rail, a front and rear adjustment slider, a wire-filling bracket, a wire feeding nozzle, a wire feeding tube mounting block and a wire feeding tube joint, wherein:

[0019] In an improvement to the above-mentioned laser wire-filling welding bracket, a mounting flange is provided on the lateral side of the bracket.

[0020] Compared with the prior art, the present invention has the following beneficial effects: since the welding bracket is not installed and fixed to the copper nozzle of the welding gun, the coaxiality of the welding gun caused by the hard connection between the copper nozzle of the welding gun and the welding bracket can be avoided; in addition, since the front and rear adjustment sliders form a right angle with the gun head mounting plate, and a straight opening for the copper nozzle of the welding gun to pass through is provided on the front and rear adjustment sliders, when the welding gun is installed on the gun head mounting plate, the copper nozzle can avoid the front and rear adjustment sliders and be protected by the three sides of the front and rear adjustment sliders, thereby preventing the robot from colliding and damaging the copper nozzle of the welding gun, which can make the laser welding structure more compact, reduce welding gun interference and robot collision damage to welding coaxiality, and thus improve the quality of laser welding; at the same time, since the front and rear adjustment sliders can be adjusted in three dimensions up and down, left and right, and front and back through the upper and lower adjustment plates, left and right adjustment blocks and front and rear adjustment slide rails, this can meet the position adjustment requirements of the welding wire in different occasions, thereby improving the accessibility of welding gun welding and ensuring the quality of laser welding.

[0031] There is a pair of front and rear adjustment rails 50, one end of which is fixed to both sides of the lower portion of the left and right adjustment blocks 40 respectively; front and rear adjustment slots 51 are provided on the sides of the front and rear adjustment rails 50;

[0032] The front-to-back adjustment slider 60 is U-shaped, with its two ends slidably disposed in the front-to-back adjustment slots 51 of the pair of front-to-back adjustment rails 50. A front-to-back adjustment guide slot 61 is provided on the side surfaces of the end portions of the front-to-back adjustment slider 60. The front-to-back adjustment slider 60 is fixed to the front-to-back adjustment rail 50 with bolts passing through the front-to-back adjustment guide slot 61 for front-to-back adjustment. The straight opening 62 of the front-to-back adjustment slider 60 allows the copper nozzle 300 of the welding gun to pass vertically therethrough. The front-to-back adjustment slider 60 forms a right-angled bracket with the gun head mounting plate 20.

[0033] The wire filling bracket 70 is vertically mounted on one side of the front and rear adjustment slider 60;

[0034] The wire feeding nozzle 80 is provided at the lower portion of the wire filling bracket 70;

[0035] A height adjustment slot 91 is provided on the wire feed tube mounting block 90; the wire feed tube mounting block 90 is fixed to the upper middle portion of the wire filling bracket 70 by passing a bolt through the height adjustment slot 91 to adjust the height of the wire feed tube mounting block 90;
