[0046] 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.

[0047] Example 1:

[0048] like Figures 1 to 4 As shown, this embodiment provides a welding torch assembly, including a support, a seam-finding camera mounted on the support, and a first plane automatic adjustment mechanism. A second plane manual adjustment mechanism is mounted on the execution end of the first plane automatic adjustment mechanism, and a welding torch is mounted on the execution end of the second plane manual adjustment mechanism. The plane of movement of the execution end of the first plane automatic adjustment mechanism is parallel to the plane of movement of the execution end of the second plane manual adjustment mechanism.

[0049] Combination Figures 1 to 5 As shown, the first planar automatic adjustment mechanism includes two vertically arranged X-axis U-shaped seats and Y-axis U-shaped seats. The X-axis U-shaped seats are fixed to the support by bolts, and the X-axis lead screw is rotatably mounted on the X-axis U-shaped seats; the X-axis stepper motor is fixed to one end of the X-axis U-shaped seats, and the X-axis stepper motor is connected to one end of the X-axis lead screw through a coupling; an X-axis guide rail parallel to the X-axis lead screw is also fixed on the X-axis U-shaped seats, and an X-axis slider is slidably mounted on the X-axis guide rail and threadedly connected to the X-axis lead screw.

[0050] The Y-axis U-shaped seat is bolted to the X-axis slider, and the Y-axis lead screw is rotatably mounted on the Y-axis U-shaped seat. A Y-axis stepper motor is fixed to one end of the Y-axis U-shaped seat, and the Y-axis stepper motor is connected to one end of the Y-axis lead screw via a coupling. A Y-axis guide rail parallel to the Y-axis lead screw is also fixed to the Y-axis U-shaped seat, and the Y-axis slider is slidably mounted on the Y-axis guide rail and threadedly connected to the Y-axis lead screw. The Y-axis slider is the actuator of the first planar automatic adjustment mechanism, and an L-shaped connecting plate for mounting the second planar manual adjustment mechanism is fixed to the Y-axis slider.

[0051] The weld seam locating camera is positioned parallel to the Y-axis lead screw. During operation, the support moves along the workpiece to be welded, and the weld seam locating camera detects the position of the weld seam in real time and transmits the data to the host computer. The host computer then adjusts the position of the welding torch accordingly based on the weld seam position, ensuring that the welding torch is correctly aligned with the weld seam to complete the welding process.

[0052] Example 2:

[0053] Based on the above embodiment one, and further combined with Figure 6 and Figure 7 As shown, the second planar manual adjustment mechanism is used for manual adjustment and calibration of the welding torch's initial working position. Since the second planar manual adjustment mechanism is only used for small-range calibration, the adjustment range of its actuator is smaller than that of the first planar manual adjustment mechanism.

[0054] The second planar manual adjustment mechanism includes two vertically arranged x-direction U-shaped seats and y-direction U-shaped seats. The x-direction U-shaped seats are fixed to the L-shaped connecting plate by bolts; an x-direction lead screw is rotatably mounted on the x-direction U-shaped seats, and an intermediate slider is threaded onto the x-direction lead screw. The inner end of the intermediate slider is slidably connected to the x-direction U-shaped seats along the direction of the x-direction lead screw; an x-direction handwheel is fixed to one end of the x-direction lead screw, and the x-direction lead screw can be rotated by the x-direction handwheel.

[0055] A y-axis lead screw is rotatably mounted on the y-axis U-shaped base, perpendicular to the x-axis lead screw. A y-axis handwheel is fixed to one end of the y-axis lead screw, allowing rotation of the lead screw. The outer end of the intermediate slider is slidably connected to the y-axis U-shaped base along the direction of the y-axis lead screw, and the intermediate slider is also threadedly connected to the y-axis lead screw. The y-axis U-shaped base serves as the actuator of the second-plane manual adjustment mechanism. A welding torch mounting plate is fixed to the y-axis U-shaped base, with one end of the mounting plate securing the welding torch to a clamp.

[0056] Example 3:

[0057] Based on the above embodiments, combined with Figure 1 and Figure 8As shown, this embodiment provides a welding device, including a traveling frame on which multiple welding torch assemblies are mounted. The multiple welding torch assemblies are arranged in one row or two staggered rows on the traveling frame.

[0058] During operation, the traveling frame moves along the workpiece to be welded, with the weld seam locating camera positioned directly above the weld seam. During the movement, the weld seam locating camera detects the weld seam position in real time and transmits the data to the host computer. The host computer adjusts the welding torch position according to the delay corresponding to the weld seam position, ensuring that the welding torch is correctly aligned with the weld seam and automatically completing the welding process.

[0059] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. 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. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
