[0027] The following uses specific embodiments to illustrate the present invention, but it is not a limitation to the invention.

[0028] Embodiment 1 like Figures 1 - 7 As shown, in this embodiment, a wheel hub painting intelligent conveyor line is provided, including a support rail 1, a suspension mechanism 3 and a limit plate 2.

[0029] The support track 1 is a continuous annular track. A conveying channel 101 with an opening at the bottom is provided inside the support track 1. The support track 1 provides basic structural support for the entire conveying line. The internal conveying channel 101 is the path for the suspension mechanism 3 to move. Its annular structure enables the conveying process to be cyclical, forming a continuous conveying system. The suspended wheel hub is carried to ensure the stable operation of the entire conveying line. Its continuous annular design ensures the continuity and sustainability of the conveying process, which is conducive to the orderly development of the wheel hub coating process.

[0030] The suspension mechanism 3 includes a driving part 31 and a suspension part 32, wherein the driving part 31 is movably arranged in the conveying channel 101, the suspension part 32 is installed at the bottom of the driving part 31, and the lower end of the suspension part 32 extends downward from the opening of the conveying channel 101. The driving part 31 moves in the conveying channel 101, driving the suspension part 32 connected thereto to move. The driving part 31 can be moved by a transmission device such as a motor and a chain. The suspension part 32 is installed at the bottom of the driving part 31, and its lower end extends downward from the opening at the end of the conveying channel 101, and can be used to suspend the wheel hub. The suspension rod in the suspension part 32 can be rotated to facilitate the adjustment of the posture of the wheel hub; the suspension mechanism 3 is responsible for suspending the wheel hub and realizing its movement in the conveying channel 101, the driving part 31 provides the moving power, and the suspension part 32 ensures the stable suspension of the wheel hub. The rotation function of the suspension rod helps to adjust the angle of the wheel hub during the painting process, so that the painting is more uniform.

[0031] The limit plate 2 is assembled at the bottom of the support track 1 along the conveying direction of the conveying channel 101, and the limit plate 2 is arranged on the periphery of the conveying channel 101. When passing through a curve, under the action of centrifugal force, the suspension part 32 will be subjected to an outward force, thereby causing the suspension part 32 and the wheel hub to move outward and deviate from the preset track. The limit plate 2 can generate a resistance to the suspension part 32 to prevent the suspension part 32 and the wheel hub from deviating from the track.

[0032] Among them, the suspension part 32 includes a rotatable suspension rod, and a stabilizing unit is installed on the suspension rod. The stabilizing unit includes a pull rod 4 rotatably installed outside the suspension rod. A limiting groove is provided on the limiting plate 2. One end of the pull rod 4 away from the suspension rod is slidably installed inside the limiting groove. The pull rod 4 cooperates with the limiting groove on the limiting plate 2. During the movement of the suspension mechanism 3, the pull rod 4 slides in the limiting groove, restricting the swing of the suspension part 32, enhancing the stability of the suspension mechanism 3 in suspending the wheel hub during movement, and preventing the wheel hub from shaking and affecting the painting quality. Especially when the suspension mechanism 3 passes through a bend, under the action of centrifugal force, the suspension part 32 will receive a force towards the outside, causing both the suspension part 32 and the wheel hub to tend to move outward, and may even deviate from the preset track. The limiting plate 2, through the cooperation of the limiting groove and the pull rod 4, can effectively resist the influence of this centrifugal force, restrict the outward movement of the suspension part 32 and the wheel hub, ensure that they always operate stably within the preset track, and effectively guarantee the smooth progress of the wheel hub painting process.

[0033] Embodiment 2 As Figures 1 - 7 shown, on the basis of Embodiment 1, this embodiment provides a stabilizing structure for the suspension rod, which is specifically as follows: The suspension rod includes a first rod body 321 and a second rod body 322 connected by a universal joint. The first rod body 321 is connected to the driving part 31, and the second rod body 322 is hinged at the lower end of the second suspension rod. The number of pull rods 4 is two, and one end of each of the two pull rods 4 is rotatably installed outside the second rod body 322. The universal joint between the first rod body 321 and the second rod body 322 can ensure that the second rod body 322 can bend in any direction. When the suspension mechanism 3 encounters various complex situations during transportation, the second rod body 322 can flexibly adjust its posture, avoiding being unable to adapt due to rigid connection and resulting in the rod body breaking, improving the flexibility and adaptability of the suspension rod, effectively protecting the suspension rod, and ensuring that the suspension part 32 can stably suspend the wheel hub and work properly under various working conditions.

[0034] Limit blocks 5 are installed at one end of each of the two pull rods 4 away from the second rod body 322. The limit blocks 5 are slidably installed inside the limiting groove, and an elastic body 6 is installed between the two limit blocks 5. When the suspension rod drives the wheel hub to accelerate, decelerate or pass through a bend, the suspension part 32 will shake or displace due to the force. At this time, the elastic body 6 can contract or stretch, changing the distance between the two limit blocks 5 and the angle between the pull rods 4, playing a buffering role for the second rod body 322, buffering the impact force received by the suspension rod under special working conditions, protecting the rod body from bending and breaking, further enhancing the stability of the suspension mechanism 3, reducing the shaking of the wheel hub, and ensuring the painting quality of the wheel hub.

[0035] The angle between the two pull rods 4 is R, where R is greater than 90 degrees and less than 180 degrees. This angle range can enable the pull rod 4 to maintain the best mechanical performance when restricting the swing of the suspension part 32 and providing buffering. When the angle is less than 90°, the constraint effect of the pull rod 4 on the suspension part 32 may be poor. When it is greater than 180°, it may affect the flexible movement and buffering effect of the suspension part 32. Ensure that the pull rod 4 exerts the best performance in restricting the swing of the suspension part 32 and buffering external forces, ensure the stable operation of the suspension mechanism 3, and improve the overall performance of the intelligent conveying line for hub painting.

[0036] The limit block 5 is rotatably installed on the pull rod 4. The limit groove includes a horizontal groove and a vertical groove. The limit block 5 is snapped into the vertical groove. A roller is rotatably installed on the limit block 5, and the roller abuts against the inner wall of the vertical groove. When the suspension mechanism 3 moves, the limit block 5 can slide smoothly in the vertical groove. The rolling of the roller can reduce the friction force. At the same time, the limit block 5 can rotate on the pull rod 4, enabling it to better adapt to the direction of the limit groove, flexibly adjust the direction, reduce the friction between the limit block 5 and the limit groove, improve the smoothness of the movement of the suspension mechanism 3, ensure that the limiting effect and stability of the limiting plate 2 on the suspension part 32 are not hindered, and ensure the smooth operation of the conveying line.

[0037] A support plate 13 is rotatably installed in the middle of the first rod body 321. A support groove is provided on the limiting plate 2. A runner is rotatably installed on the support plate 13, and the runner is rollingly installed inside the support groove. When the suspension mechanism 3 moves, the runner rolls in the support groove. The support groove provides a supporting force for the runner, sharing part of the weight of the first rod body 321, reducing the stress generated by the first rod body 321 due to suspending the hub and its own movement, supporting the first rod body 321, reducing its stress burden, prolonging the service life of the suspension rod, enhancing the stability of the suspension mechanism 3, and helping to ensure the stability of the hub painting process.

[0038] Embodiment III As Figures 1 - 7 shown, on the basis of Embodiment I and Embodiment II, this embodiment provides the structure of the driving part 31, which is specifically as follows: The driving part 31 includes a frame 7 which is adapted to the conveying channel 101. The first rod body 321 is rotatably installed on the frame 7. Lower rollers 8 are rotatably installed on both sides of the bottom of the frame 7, and side rollers 9 are rotatably installed on both sides of the frame 7. When a power source such as a motor drives the frame 7 to move, the lower rollers 8 and the side rollers 9 roll at corresponding positions in the conveying channel 101, driving the frame 7 and the suspension part 32 connected thereto to move, providing moving power for the suspension mechanism 3, ensuring that the suspension part 32 can move smoothly and accurately in the conveying channel 101, realizing the conveying function of the wheel hub, and being the key power component for the operation of the suspension mechanism 3. A motor is fixed on the frame 7, a first gear is fixed on the output shaft of the motor, a second gear is sleeved outside the first rod body 321, and the first gear is meshed and connected with the second gear. By controlling the rotation speed and direction of the motor, the rotation angle and speed of the first rod body 321 and the suspension part 32 can be flexibly adjusted, the rotation of the suspension rod can be precisely controlled, the attitude of the wheel hub can be conveniently adjusted, the painting requirements at different angles during the wheel hub painting process can be met, and the uniformity and quality of the wheel hub painting can be improved.

[0039] The number of the lower rollers 8 and the side rollers 9 is four, which are respectively arranged at the four corners of the frame 7. The lower rollers 8 on both sides are pressed against the side walls of the conveying channel 101, and the side rollers 9 are pressed against the steps of the conveying channel 101. During the movement of the frame 7, these rollers play a guiding and supporting role, ensuring that the frame 7 moves in the conveying channel 101 along a predetermined trajectory, preventing the frame 7 from shifting or shaking, precisely guiding and stably supporting the frame 7 of the driving part 31, improving the accuracy and stability of the movement of the suspension mechanism 3, ensuring the position accuracy of the wheel hub during the conveying process, and providing good conveying conditions for the wheel hub painting.

[0040] A telescopic rod 10 is installed inside the frame 7, a spring 12 is installed inside the telescopic rod 10, an arc plate 11 is rotatably installed above the telescopic rod 10, rollers are rotatably installed at both ends of the arc plate 11, and the rollers are pressed against the top end of the conveying channel 101. When the driving part 31 moves, the arc plate 11 and the rollers can adapt to the shape change of the top end of the conveying channel 101, and the spring 12 and the telescopic rod 10 can adjust the contact pressure between the arc plate 11 and the top end of the channel according to the actual situation, playing a buffering and adaptive adjustment role, buffering the impact force from the top end of the conveying channel 101 during the movement of the driving part 31, enhancing the fitting degree between the driving part 31 and the conveying channel 101, improving the smoothness of the operation of the suspension mechanism 3, and ensuring the reliable operation of the conveying line.

[0041] Working principle: The annular conveying channel 101 of the support track 1 provides a continuous moving path for the suspension mechanism 3. The driving part 31 drives the suspension part 32 to operate in a cycle through motor and gear transmission, realizing the continuous conveying of the wheel hub.

[0042] The end limit block 5 of the pull rod 4 of the suspension part 32 slides in the limit groove, and the centrifugal force is buffered by the elastic body 6 to prevent the hub from moving outwards when turning.

[0043] The first rod body 321 and the second rod body 322 are connected by a universal joint, allowing the hub to tilt at multiple angles to meet the requirements of the painting posture.

[0044] The lower roller wheels 8 and the side roller wheels 9 at the four corners of the frame body 7 are attached to the side wall and the step of the conveying channel 101 to ensure the accuracy of the moving track.

[0045] The telescopic rod 10 and the arc plate 11 are pressed against the top end of the conveying channel 101 by the spring 12 to reduce vibration and impact.

[0046] The motor drives the first gear to engage with the second gear to control the rotation of the suspension rod and accurately adjust the painting angle of the hub.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention.
