[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1:

[0040] like Figures 1 to 5As shown, this utility model provides a walking guide device for a welding machine, including a frame 1, with walking wheels 2 and straightening wheels 3 installed under the frame 1, and an automatic welding device mounted on the frame 1. The frame 1 utilizes the walking wheels 2 and straightening wheels 3 to achieve stable movement on the trailer floor, extending the working range of the automatic welding device and making it suitable for welding long trailer floor panels.

[0041] The frame 1 is a truss structure with two traveling wheels 2 at each end, arranged in a rectangular pattern. During operation, the rolling supports of the traveling wheels 2 at both ends rest on the sides of the upper surface of the carriage floor, providing support for the frame 1 and preventing interference with welding operations. Multiple centering wheels 3 are located at both ends of the frame 1, positioned on the end faces of both sides of the carriage floor. During operation, the centering wheels 3 clamp onto the sides of the workpiece to be welded, limiting the movement of the frame 1 and ensuring stable movement along the carriage floor.

[0042] In this embodiment, a walking drive motor 21 is connected to one of the pair of walking wheels 2. For example... Figure 3 As shown, an outer ear plate 22 and an inner ear plate 23 are fixed under the frame 1, and coaxial mounting holes are provided on the outer ear plate 22 and the inner ear plate 23. The shaft of the walking wheel 2 is rotatably mounted on the outer ear plate 22, and the walking drive motor 21 is fixed on the inner ear plate 23. The output end of the walking drive motor 21 is connected to the shaft of the walking wheel 2 through a coupling 24.

[0043] Example 2:

[0044] Based on the above embodiment one, combined with Figures 1 to 5 As shown, in this embodiment, three centering wheels 3 are provided, respectively, on both sides of the frame 1. The separately arranged centering wheel 3 is located on the center line of the other two centering wheels 3, forming an isosceles triangle structure. The centering wheels 3 are rotatably mounted on supports 31. The two centering wheels 3 on one side are directly fixed to the frame 1 via supports 31, while the supports 31 of the separately arranged centering wheel 3 on the other side are fixed to the frame 1 via a lateral adjustment structure 4. The lateral adjustment structure 4 allows adjustment of the distance between the centering wheels 3 on both sides, enabling them to clamp tightly against the sides of the carriage floor, ensuring the stability of the frame 1 during movement.

[0045] Example 3:

[0046] Based on the above-described embodiment two, and further combined with Figure 6 and Figure 7As shown, this embodiment provides a transverse adjustment structure 4, mainly including a U-shaped base 41, a slide rail 42 fixed on the U-shaped base 41, and a slider 45 slidably mounted on the slide rail 42. A lead screw 43 is rotatably mounted on the left end of the U-shaped base 41, and a transverse adjustment motor 44 is fixed to the right end of the U-shaped base 41, with the motor fixedly connected to the right end of the lead screw 43. A support seat is also rotatably connected to the right end of the lead screw 43 to improve its stability.

[0047] The slider 45 has a threaded hole, and a lead screw 43 is fitted into the threaded hole. The slider 45 can be moved along the slide rail 42 on the U-shaped seat 41 by the drive of the lead screw 43 via the lateral adjustment motor 44. The upper end of the connecting frame 46 is fixed to the slider 45, and four limiting bolts 47 are inserted between the lower end of the connecting frame 46 and the support 31 of the centering wheel 3. Under the constraint of the cap and nut of the limiting bolts 47, the support 31 and the connecting frame 46 can move a certain distance relative to each other along the limiting bolts 47. A spring 48 is fitted on each limiting bolt 47, and the spring 48 rests between the support 31 and the connecting frame 46. The lateral adjustment structure 4 is used to adjust the distance between the centering wheels 3 on both sides, and the spring 48 provides a preload to ensure that even when the width of the car floor fluctuates, the centering wheels 3 on both sides can still be pressed tightly against the sides of the car floor.

[0048] Working principle:

[0049] Combination Figure 1 and Figure 8 As shown, by adjusting the horizontal adjustment motor 44, the two sides of the straightening wheel 3 are moved away from each other, the distance between the two sides of the straightening wheel 3 is increased, and the frame 1 is hoisted onto the bottom plate of the carriage, so that the two sides of the traveling wheel 2 roll and support the upper surface of the two sides of the bottom plate of the carriage.

[0050] Then, by adjusting the horizontal adjustment motor 44, the two sides of the straightening wheel 3 are adjusted to move closer to each other. One side of the straightening wheel 3 gradually moves closer to and presses against the side of the car floor, thereby dragging the entire frame 1 to move, so that the other side of the straightening wheel 3 also presses against the other side of the car floor, thus completing the positioning of the frame 1.

[0051] Start the walking drive motor 21, which drives the walking wheels 2, thereby moving the entire frame 1 along the trailer floor; this enables the position adjustment of the automatic welding equipment on the frame 1, facilitating the welding of long trailer trailer floor plates.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
