[0023] 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.

[0024] Please see Figure 1 The wheel hub laser welding dynamic tracking and positioning device in this embodiment includes a support platform 1, a gantry support frame 2 fixed on the upper surface of the support platform 1, a welding mechanism 3 provided on the top wall of the inner cavity of the gantry support frame 2, and an adjustment mechanism 4 provided on the top wall of the inner cavity of the support platform 1.

[0025] Please see Figures 2 to 3 In this embodiment, the welding mechanism 3 includes a movable module 301 fixed to the top wall of the inner cavity of the gantry support frame 2. A first electric push rod 302 is fixed to the lower surface of the movable module 301. A connecting plate 303 is fixed to the outer side of the output shaft of the first electric push rod 302. A laser welding gun 304 is fixed to the lower surface of the connecting plate 303. A mounting plate 305 is fixed to the front of the connecting plate 303. An industrial camera 306 and a laser vision sensor 307 are arranged sequentially from front to back on the lower surface of the mounting plate 305. A limiting member is provided on the right side of the lower surface of the movable module 301.

[0026] Specifically, during welding dynamic tracking and positioning, the laser line emitted by the laser vision sensor 307 illuminates the weld surface to form a contour, and the industrial camera 306 receives the reflected light from a specific angle, thereby accurately identifying the geometric features of the weld such as its position, width, and depth.

[0027] Specifically, the limiting component includes a fixed plate 308 fixed to the right side of the lower surface of the movable module 301, a U-shaped plate 309 fixed to the left side of the fixed plate 308, a slider 310 slidably connected to the outside of the U-shaped plate 309, and a movable plate 311 fixed to the left side of the slider 310. The bottom end of the movable plate 311 is fixedly connected to the upper surface of the connecting plate 303.

[0028] It should be noted that during welding, the industrial camera 306 and the laser vision sensor 307 acquire image information of the welding area in real time and transmit the data to the main controller. The main controller calculates the deviation of the welding position based on the image information and adjusts the position of the laser welding gun 304 through the moving module 301 and the first electric push rod 302 to achieve dynamic tracking and positioning, ensuring welding accuracy. The laser welding gun 304 performs laser welding operation according to the instructions of the main controller to complete the welding of the wheel hub.

[0029] Please see Figure 4 In this embodiment, the adjustment mechanism 4 includes a motor 401 fixed to the top wall of the inner cavity of the support platform 1 by a mounting bracket. A rotating rod 402 is rotatably connected to the upper surface of the support platform 1 by a bearing. The bottom end of the rotating rod 402 rotatably passes through the support platform 1 and is fixedly connected to the outside of the output shaft of the motor 401. A fixed plate 403 is fixed to the top end of the rotating rod 402. Support pulley groups 404 are provided on both the left and right sides of the lower surface of the fixed plate 403. A support rod 405 is fixed to the upper surface of the fixed plate 403. A support plate 406 is hinged to the top end of the support rod 405 by a hinge seat.

[0030] Specifically, the adjustment mechanism 4 also includes a second electric push rod 407 hinged to the left side of the upper surface of the fixed plate 403 via a hinge seat. The outer side of the output shaft of the second electric push rod 407 is hinged to the left side of the lower surface of the support plate 406 via the hinge seat. A third electric push rod 408 is fixed on both the left and right sides of the upper surface of the support plate 406. An arc-shaped clamping plate 409 is fixed on the outer side of the output shaft of the third electric push rod 408 on both the left and right sides. The support pulley group 404 includes a connecting rod. The bottom end of the connecting rod is rotatably connected to a support pulley. The bottom end of the support pulley is in contact with the upper surface of the support platform 1. The arc-shaped clamping plate 409 is slidably connected to the upper surface of the support plate 406. An anti-slip rubber layer is fixed on the opposite side of the arc-shaped clamping plates 409 on both the left and right sides.

[0031] It should be noted that when the wheel hub is placed on the support plate 406, the third electric push rods 408 on both sides are activated simultaneously to push the arc-shaped clamping plates 409 on both sides to clamp the wheel hub, ensuring the stability of the wheel hub during the welding process. The motor 401 drives the rotating rod 402 to rotate, which in turn drives the fixed plate 403 and the support plate 406 to rotate, thereby realizing the rotation adjustment of the wheel hub. At the same time, the second electric push rod 407 adjusts the tilt angle of the support plate 406 to put the wheel hub in the optimal welding position.

[0032] It should be noted that the installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effects can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the wheel hub is placed on the support plate 406. Simultaneously activating the third electric push rods 408 on both sides pushes the arc-shaped clamping plates 409 on both sides to clamp the wheel hub, ensuring its stability during welding. The motor 401 drives the rotating rod 402 to rotate, causing the fixed plate 403 and support plate 406 to rotate, thus adjusting the wheel hub's rotation. Simultaneously, the second electric push rod 407 adjusts the tilt angle of the support plate 406 to position the wheel hub in the optimal welding position. During welding, the industrial camera 306 and laser vision sensor 307 collect real-time image information of the welding area and transmit the data to the main controller. The main controller calculates the welding position deviation based on the image information and adjusts the position of the laser welding gun 304 via the moving module 301 and the first electric push rod 302 to achieve dynamic tracking and positioning, ensuring welding accuracy. The laser welding gun 304 performs laser welding operations according to the main controller's instructions, completing the wheel hub welding.
