[0043] Hereinafter, a welding tool for producing automobile door panels according to one embodiment of the present invention will be described with reference to the accompanying drawings.

[0044] Please refer to Figure 1-Figure 3As shown, as an embodiment of the present invention, a welding tool for automobile door panel production is provided, comprising a top plate 1, and a supporting assembly and a positioning assembly provided on the top plate 1;

[0045] Among them, the positioning component can press and position the door panel to be processed above the supporting component;

[0046] Support legs 101 are provided below the top plate 1;

[0047] Regarding support components, including:

[0048] The support plate 2 is arranged on the upper end surface of the top plate 1;

[0049] Specifically, the support plate 2 is fixed to the upper end surface of the top plate 1 by means of mounting bolts 2a, and a countersunk hole for accommodating the mounting bolts 2a is provided on the support plate 2;

[0050] Among them, a plurality of mounting holes 201 are set through the support plate 2, and the inner wall of each mounting hole 201 is engraved with an internal thread 201a;

[0051] Specifically, a number of mounting holes 201 are evenly distributed in a rectangular array on the support plate 2;

[0052] The support sheet 202 is assembled on the support plate 2 by a first screw 202a;

[0053] Specifically, the first screw 202a matches the internal thread 201a on the inner wall of the mounting hole 201;

[0054] The support sheet 202 is made of rubber, resin or metal, and can be customized into irregular geometric shapes according to its contact surface with the door panel to be processed (cutting or grinding the support sheet 202 made of rubber, resin or metal is based on existing technology and is intended to provide a support sheet 202 that fits the door panel to be processed);

[0055] During use, the staff selects an appropriate number of support sheets 202 (grinding is performed according to the contact surface between the support sheets 202 and the door panel to be processed) and the first screw 202a according to the number of support points required for the door panel to be processed, and assembles them onto the support plate 2;

[0056] Regarding positioning components, including:

[0057] The mounting base 3 is fixed on the top plate 1 and is located outside the support plate 2;

[0058] The connecting beam 301 is configured to be arc-shaped and is rotatably mounted on the top of the mounting base 3;

[0059] Specifically, the connecting beam 301 and the mounting base 3 can be fastened by fastening bolts 301 - 1 ;

[0060] The pressing sheet 302 is mounted on the end of the connecting beam 301 via a second screw 302-1;

[0061] The second screw 302-1 passes through the pressing plate 302 and is arranged perpendicular to the end surface of the pressing plate 302. The connecting beam 301 is provided with a threaded hole that matches the second screw 302-1. That is, by rotating the second screw 302-1, the operator can adjust the position of the pressing plate 302 relative to the connecting beam 301.

[0062] In addition, a hand wheel 302 - 2 is provided at the end of the second screw 302 - 1 away from the pressing plate 302 , so that the staff can rotate the second screw 302 - 1 and adjust the position of the pressing plate 302 conveniently.

[0063] During use, the staff adjusts the height and position of the support plate 202 on the support assembly, places the door panel to be processed on the support assembly, and the support plate 202 and the first screw 202a support the door panel to be processed. The connecting beam 301 is rotated until its end away from the top plate 1 is located on the door panel to be processed, and the fastening bolt 301-1 is tightened to complete the fixation of the connecting beam 301 relative to the top plate 1. The handwheel 302-2 is rotated to drive the second screw 302-1 to rotate, thereby completing the position adjustment of the pressing plate 302 relative to the connecting beam 301, and then realizing the clamping of the door panel to be processed by the pressing plate 302 and the support plate 202, thereby realizing the clamping and fixation of the door panel to be processed before welding.

[0064] Please refer to Figure 1 、 Figure 4-Figure 6 As another embodiment of the present invention, there is provided an auxiliary movement mechanism for the welder 404 of the above embodiment, which includes:

[0065] The first slideway 4 is provided on the side wall of the top plate 1;

[0066] Specifically, the first slideway 4 is threadedly assembled with the side wall of the top plate 1;

[0067] The second slide 402 is slidably arranged with the first slide 4 via the slider 401;

[0068] The sleeve 403 is slidably disposed on one side of the second slideway 402;

[0069] The sliding direction of the second slide 402 along the first slide 4 and the sliding direction of the sleeve 403 along the second slide 402 are located perpendicularly in the same plane, and the extension and contraction direction of the sleeve 403 is perpendicular to the plane. That is, based on the sliding of the first slide 4 and the second slide 402, the extension and contraction of the sleeve 403 are coordinated to complete the auxiliary movement support in the "X" direction, "Y" direction, and "Z" direction;

[0070] In this embodiment, the sliding direction of the slider 401 relative to the first slideway 4 is referred to as the "X" direction, the sliding direction of the sleeve 403 relative to the second slideway 402 is referred to as the "Z" direction, and the extension and contraction direction of the sleeve 403 body is referred to as the "Y" direction;

[0071] The end of the sleeve 403 away from the second slide 402 is set on the mounting flange 403-1, and the welding machine 404 (derived from the existing technology and intended for welding automobile door panels) is fixed to the end of the sleeve 403 through the mounting flange 403-1;

[0072] The fastening screw 4 - 1 is used to achieve relative fixed positioning between the slider 401 and the first slideway 4 , between the sleeve 403 and the second slideway 402 , and between the sleeves 403 and the sleeves 403 ;

[0073] Specifically, the number of sleeves 403 is determined according to the size of the door panel to be processed, that is, a plurality of sleeves 403 are arranged end to end in a sliding manner to provide support for the welder 404 to move from one end of the door panel to be processed to the other end;

[0074] The other structures are the same as those in the above embodiment.

[0075] During use, the worker needs to move the welding machine 404 to perform the welding operation. Currently, the worker holds the welding machine 404 and moves it. This method relies heavily on the worker's welding experience and consumes physical strength during long production periods, which can affect the welding effect. Therefore, the worker adjusts the position of the support sheet 202 on the support plate 2 and the placement angle of the door panel to be processed relative to the support plate 2, so that the linear welding area on the door panel to be processed is parallel to one of the above-mentioned "X", "Y" and "Z" directions.

[0076] That is, if welding work in the "Y" direction is required, the slider 401 and the first slide 4 as well as the sleeve 403 and the second slide 402 are fixed to the required position, leaving only the telescopic freedom of the sleeve 403 body, and the welding machine 404 is started. The welding work on the door panel to be processed is completed through the support of the sleeve 403 on the welding machine 404 and the linear displacement freedom of the sleeve 403 itself;

[0077] If welding operations in the "X" and "Z" directions are required, the slides or sleeves 403 on other degrees of freedom are fixed, and only the displacement freedom of the slider 401 or sleeve 403 on this degree of freedom is retained, that is, the mobile support of the welding machine 404 in multiple directions is achieved, which saves the physical strength of the workers and avoids the workers' hand shaking caused by holding the welding machine 404 for a long time, thereby improving the welding effect.

[0078] Compared with the prior art, the present invention has the following features:

[0079] The use of screws in conjunction with the support sheet 202 and the pressing sheet 302 for fixing can adapt to different door panels to be processed, especially door panels of different shapes and with several curved surfaces, and can provide effective support to avoid poor welding caused by deformation of the tooling;

[0080] It is equipped with an auxiliary moving mechanism, which is based on a multi-degree-of-freedom sliding and fixable structure setting, and can assist workers in moving the welding machine 404, avoiding hand shaking and line changes caused by workers' fatigue due to long-term work, thereby improving welding effects.

[0081] The present invention is not limited to the embodiment, and various modifications can be made without departing from the spirit of the present invention.
