Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub processing technology, and in particular to a suspension device for automotive wheel hub surface spraying treatment. Background Technology

[0002] In the automotive manufacturing and wheel refurbishing industry, wheel surface spraying is a key process to ensure the appearance quality of the wheel and improve its corrosion resistance. As the core component that fixes and supports the wheel during the spraying process, the performance of the suspension device directly affects the spraying efficiency, paint layer quality, and manual operation intensity.

[0003] Existing suspension systems are highly dependent on manual operation, resulting in high labor intensity and difficulty in ensuring positioning accuracy. Before clamping and fixing the wheel hub, due to the lack of effective support and position adjustment structures, operators must manually move the wheel hub, especially larger and heavier ones, to precisely align it with the center of the clamping fixture. This process requires prolonged lifting or repeated adjustments, easily leading to operator fatigue and wheel hub positioning deviations due to manual operation errors. Furthermore, existing suspension systems lack flexibility in adjusting the wheel hub's posture, easily creating blind spots during spraying, and have poor versatility in support structures. Most devices can only achieve rotation in one direction, or require manual removal of the wheel hub for posture adjustment, failing to flexibly change the wheel hub's tilt angle or circumferential position according to spraying requirements. To overcome these disadvantages, this utility model provides a suspension device for automotive wheel hub surface spraying treatment. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a suspension device for spraying coating on the surface of automobile wheel hubs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a suspension device for spray coating treatment of automobile wheel hubs, comprising a base plate, a rotating frame fixedly connected to one side of the base plate, a turntable rotatably connected to one side of the rotating frame, a support plate fixedly connected to one side of the turntable, a rotating rod rotatably connected to one side of the support plate, a sliding groove fixedly connected to one end of the rotating rod, a slider slidably connected to the sliding groove, a clamping assembly provided on one side of the slider, a moving assembly provided on the sliding groove, a connecting block fixedly connected to one side of the sliding groove, an insert rod fixedly connected to one side of the connecting block, a support assembly provided on one side of the base plate, a control assembly provided on one side of the base plate, and a rotating assembly provided on one side of the rotating frame.

[0006] Furthermore, the moving component includes a bidirectional threaded rod rotatably connected to the slide rail, a threaded hole is provided on one side of the slider, the threaded hole and the bidirectional threaded rod are threadedly connected, a first servo motor is fixedly connected to one side of the slide rail, and the output end of the first servo motor passes through the slide rail and is fixedly connected to one end of the bidirectional threaded rod.

[0007] Furthermore, the support assembly includes a first electric hydraulic cylinder fixedly connected to one side of the base plate. The output end of the first electric hydraulic cylinder is fixedly connected to a rotating seat. A plurality of conveying rollers are rotatably connected to the rotating seat. Limiting telescopic rods are fixedly connected to one side of the base plate and to both sides of the electric hydraulic cylinder. The output end of the limiting telescopic rod is fixedly connected to one side of the rotating seat.

[0008] Furthermore, the control assembly includes a plurality of control pedals fixedly connected to one side of the base plate, and a PLC controller is fixedly connected to one side of the base plate. The PLC controller and the control pedals are electrically connected.

[0009] Furthermore, the rotating assembly includes a rotating motor fixedly connected to one side of the rotating frame, the output end of the rotating motor passing through the rotating frame and fixedly connected to one side of the turntable, and a second servo motor fixedly connected to one side of the support plate, the output end of the second servo motor passing through the support plate and fixedly connected to one end of the rotating rod.

[0010] The beneficial effects of this utility model are: When using this utility model, 1. The support components enable convenient support and position adjustment of the wheel hub. The electric hydraulic cylinder on the base plate can drive the rotating seat to rise and fall, thereby driving the conveyor rollers on the rotating seat to adjust the height. The conveyor rollers can assist the wheel hub in translation to adjust the horizontal position. This process can complete the height and horizontal position calibration of the wheel hub without the need for operators to carry the wheel hub for a long time. At the same time, the plug on the connecting block on one side of the slide can be inserted into the threaded hole of the wheel hub to quickly achieve the initial positioning of the wheel hub, effectively reducing the labor intensity of manual handling and positioning, and avoiding clamping deviations caused by operational errors during manual positioning.

[0011] 2. The painting position of the wheel hub can be flexibly adjusted by the rotating assembly. The rotating motor on one side of the rotating frame can drive the turntable to rotate, and the turntable further drives the support plate, rotating rod and wheel hub clamped on the slide to rotate synchronously, realizing the circumferential position adjustment of the wheel hub around the axis of the turntable. The second servo motor on one side of the support plate can drive the rotating rod to rotate, and the rotating rod drives the slide and wheel hub to rotate around the axis of the rotating rod, realizing the flexible adjustment of the wheel hub angle. Through the combination of the two rotation methods, the wheel hub can be adjusted to the optimal painting posture according to the painting requirements, avoiding the painting dead angle caused by the fixed position of the wheel hub in the traditional suspension device, and improving the flexibility and comprehensiveness of the painting operation.

[0017] As shown in the figure, the clamping assembly includes an arc-shaped clamping plate 8 fixedly connected to one side of the slider 7. Several rubber anti-slip strips 9 are fixedly connected to the arc-shaped clamping plate 8 for clamping and fixing the wheel hub.

[0018] As shown in the figure, the moving component includes a bidirectional threaded rod 10 rotatably connected to the slide 6. A threaded hole 11 is provided on one side of the slider 7. The threaded hole 11 and the bidirectional threaded rod 10 are threadedly connected. A first servo motor 14 is fixedly connected to one side of the slide 6. The output end of the first servo motor 14 passes through the slide 6 and is fixedly connected to one end of the bidirectional threaded rod 10, and is used to drive the arc-shaped clamping plate 8 on the clamping component to move.

[0019] As shown in the figure, the support assembly includes a first electric hydraulic cylinder 15 fixedly connected to one side of the base plate 1. A rotating seat 16 is fixedly connected to the output end of the first electric hydraulic cylinder 15. Several conveying rollers 17 are rotatably connected to the rotating seat 16. Limiting telescopic rods 18 are fixedly connected to one side of the base plate 1 and on both sides of the electric hydraulic cylinder 15. The output end of the limiting telescopic rod 18 is fixedly connected to one side of the rotating seat 16 for supporting the wheel hub.

[0020] As shown in the figure, the control assembly includes several control pedals 20 fixedly connected to one side of the base plate 1. A PLC controller 19 is fixedly connected to one side of the base plate 1. The PLC controller 19 and the control pedals 20 are electrically connected and used to control the equipment on the device.

[0021] As shown in the figure, the rotating assembly includes a rotating motor 21 fixedly connected to one side of the rotating frame 2. The output end of the rotating motor 21 passes through the rotating frame 2 and is fixedly connected to one side of the turntable 3. A second servo motor 22 is fixedly connected to one side of the support plate 4. The output end of the second servo motor 22 passes through the support plate 4 and is fixedly connected to one end of the rotating rod 5. It is used to adjust the position of the hub according to the spraying requirements.

[0022] Working Principle: During use, first check the entire device for damage. After inspection, the operator places the wheel hub to be painted on the conveyor roller 17 of the support assembly. A command is sent to the PLC controller 19 via the control pedal 20 on one side of the base plate 1. The PLC controller 19 controls the extension and retraction of the electric hydraulic cylinder 15, which in turn raises and lowers the rotating seat 16 until the wheel hub height is adjusted to match the insertion rod 13. Then, with the rotation of the conveyor roller 17, the wheel hub is moved horizontally, aligning the threaded hole on the wheel hub with the insertion rod 13 on the connecting block 12 on one side of the slide 6. The insertion rod 13 is then inserted into the threaded hole of the wheel hub, completing the initial positioning of the wheel hub. This process eliminates the need for operators to handle the wheel hub for extended periods, significantly reducing labor intensity. After initial positioning, the control pedal 20 triggers the PLC controller 19 to start the first servo motor 14. The output of the first servo motor 14 drives the bidirectional threaded rod 10 on the slide 6 to rotate. When the bidirectional threaded rod 10 rotates, it drives the two sliders 7 on both sides to slide towards each other along the slide groove 6. This causes the arc-shaped clamping plate 8 on one side of the slider 7 to gradually clamp the outer wall of the wheel hub. The rubber anti-slip strip 9 on the arc-shaped clamping plate 8 increases the friction with the wheel hub, preventing the wheel hub from slipping during clamping, and also prevents the clamping plate from scratching the surface of the wheel hub, ultimately achieving stable fixing of the wheel hub. Then, according to the spraying requirements, the wheel hub position is adjusted by controlling the rotating component through the control pedal 20. First, the rotating motor 21 on one side of the rotating frame 2 is started. The output end of the rotating motor 21 drives the turntable 3 to rotate. The turntable 3 synchronously drives the support plate 4, the rotating rod 5, and the fixed wheel hub on one side to rotate around the axis of the turntable 3, realizing the adjustment of the circumferential position of the wheel hub on the horizontal plane. Then, the second servo motor 22 on one side of the support plate 4 is started. The output end of the second servo motor 22 drives the rotating rod 5 to rotate. The rotating rod 5 drives the slide groove 6 and the wheel hub to rotate around the axis of the rotating rod 5, realizing the adjustment of the wheel hub tilt angle.
