Description

Technical Field

[0001] This utility model relates to the field of wheel hub production technology, specifically a flipping mechanism for automobile wheel hub production. Background Technology

[0002] Existing automotive wheel rims are adapted to the needs of different car models, balancing performance and cost, and taking into account safety, functionality and aerodynamics.

[0003] As the global automotive industry transforms towards lightweighting, intelligentization, and high-end products, automotive wheels, as key load-bearing components, are undergoing continuous upgrades in their production processes and quality standards. According to data from the China Association of Automobile Manufacturers, the global automotive wheel market exceeded $80 billion in 2024, with aluminum alloy wheels accounting for over 75%, and the penetration rate of new products such as carbon fiber composite wheels growing at an annual rate of 12%. Wheel production encompasses core processes such as casting (or forging), heat treatment, machining, surface treatment (spraying / electroplating), and inspection. The flipping operation is a crucial auxiliary process that runs through multiple stages—after casting, the wheel needs to be flipped to remove slag from the gating gate; during machining, it needs to be flipped to achieve drilling / milling on both sides; before surface treatment, it needs to be flipped to ensure uniform spraying; and during inspection, it needs to be flipped to check for defects on the inner wall. In traditional wheel production, manual flipping was the initial method: 2-3 workers used pry bars and lifting tools to flip the wheel, weighing 5-30 kg, to the target angle. This method has three major problems: First, it is inefficient, with each wheel hub taking 30-60 seconds to flip, which is difficult to match the 15-20 second / piece cycle time required by modern production lines; second, there is a risk of quality, as manual operation is prone to wheel hub collisions due to uneven force, especially since aluminum alloy wheel hubs have low surface hardness, and even minor damage requires rework; third, there are safety hazards, as long-term handling and flipping can easily lead to lumbar muscle strain for workers, and wheel hubs slipping may cause equipment damage or personal injury. The existing wheel hub production process also has the following problems. During the production of wheel hubs, operators need to repeatedly flip the wheel hubs, so there is an urgent need for a flipping mechanism for automotive wheel hub production to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a flipping mechanism for automobile wheel hub production, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a flipping mechanism for automobile wheel hub production, including a clamping arm 1, a clamping arm 2 mounted on one side of the clamping arm 1, a support shaft mounted inside the clamping arm 1, a rotating groove provided at the end of the support shaft, a connecting shaft 1 mounted on one end of the clamping arm 1, a connecting rod 1 mounted on one side of the connecting shaft 1, and a threaded rod 1 provided on one side of the connecting rod 1, a connecting shaft 2 mounted on one end of the clamping arm 2, a connecting rod 2 mounted on one side of the connecting shaft 2, a threaded rod 2 provided on one side of the connecting rod 2, a rotating drum mounted on one side of the rotating drum, a gear 1 provided on the side of the rotating drum, and gear fasteners mounted on both sides of the gear 1. A gear is mounted on one side of a fixed component and a gear fixing component. A gear connecting shaft is provided on the inner side of the gear two. A power motor is provided on one side of the gear connecting shaft. A motor fixing component is provided on one side of the power motor. A chassis component is provided at the bottom of the motor fixing component. A rotating connecting shaft is provided on the side of the chassis component away from the motor fixing component. A drive motor is provided on the side of the rotating connecting shaft away from the chassis component. A fixing plate is provided on the side of the drive motor away from the rotating connecting shaft. A fixing column is provided on the side of the fixing plate near the drive motor. A chassis slot is provided on the side of the fixing column. A rotating support plate is provided at the end of the fixing column away from the fixing plate. A wheel hub is mounted on one side of the clamping arm.

[0007] The present invention is further configured such that: clamping arm one and clamping arm two are rotatably connected by a support shaft, the support shaft is welded to the rotating groove, and the rotating groove is rotatably connected to the rotating support plate.

[0008] By adopting the above technical solution, the curved parts of clamping arm one and clamping arm two are in close contact with the side of the wheel hub, so that when clamping arm one and clamping arm two hold the wheel hub, the wheel hub can be completely fixed. The rotating groove and the rotating support plate are rotatably connected, so that when the wheel hub is flipped, the rotating support plate can continuously provide stability for the overall structure.

[0009] The present invention is further configured such that: clamping arm one and connecting rod one are rotatably connected through connecting shaft one; threaded rod one is welded to connecting rod one; clamping arm two and connecting rod two are rotatably connected through connecting shaft two; and threaded rod two and connecting rod two are welded.

[0010] By adopting the above technical solution, the connecting rod and the clamping arm are rotatably connected. When threaded rod one and threaded rod two are close to or far away, the clamping arm can clamp or loosen the hub. Because the rotating support plate and the fixed column are slidably connected, there is no need to worry about the clamping arm one and clamping arm two getting stuck at the intersection during the operation.

[0011] The present invention is further configured such that: the rotating drum is threadedly connected to the threaded rod one, the rotating drum is threadedly connected to the threaded rod two, the gear one meshes with the gear two, the gear two is welded to the gear connecting shaft, and the gear connecting shaft is rotatably connected to the power motor.

[0012] By adopting the above technical solution, the threaded rod one and the threaded rod two have opposite thread directions, which makes it convenient for the threaded rod one and the threaded rod two to move closer to each other at the same time when the drum rotates, and for the threaded rod one and the threaded rod two to move away from each other at the same time when the drum rotates.

[0013] The present invention is further configured such that: the gear fixing component is rotatably connected to the rotating drum, the gear fixing component is rotatably connected to the gear connecting shaft, and the power motor is fixedly connected to the motor fixing component.

[0014] By adopting the above technical solution, both gear fixing parts are on the rotating drum, that is, on both sides of gear one, and the two gear fixing parts are also on both sides of gear two. Therefore, the gear fixing parts restrict the left and right movement of gear one and gear two without affecting their respective rotation.

[0015] The present invention is further configured such that: the chassis component is welded to the gear fixing component, the chassis component is welded to the motor fixing component, the chassis component is welded to the rotary connecting shaft, the chassis component is rotatably connected to the chassis slot, and the rotary connecting shaft is rotatably connected to the drive motor.

[0016] By adopting the above technical solution, the power motor is fixed to the chassis component through the motor fixing component, which can provide stable rotation power for gear two. The gear fixing component is welded to the chassis component. Since the rotating drum is threadedly connected to threaded rod one and threaded rod two, when it needs to be flipped, the chassis component rotates, and then the gear fixing component rotates with the rotating drum. The threaded rod drives the clamping arm to rotate together through the connecting rod.

[0017] The present invention is further configured such that: the drive motor is fixedly connected to the fixed plate, the fixed column is welded to the fixed plate, the fixed column is welded to the chassis slot, the fixed column is slidably connected to the rotating support plate, the first clamping arm is engaged with the wheel hub, and the second clamping arm is engaged with the wheel hub.

[0018] By adopting the above technical solution, one end of the fixed column is fixed to the fixed plate, the fixed column supports the chassis component through the chassis slot, and the fixed column is slidably connected to the rotating support plate. While supporting the rotating groove, it does not affect the sliding of the rotating groove driven by the clamping arm during its movement.

[0019] In summary, the beneficial technical effects of this utility model are as follows: 1. This wheel hub production tilting mechanism uses a drive motor to rotate the chassis components, which in turn rotates clamping arms one and two, achieving the purpose of tilting the wheel hub. This improves the situation where operators need to repeatedly tilt the wheel hub during the production process. This design uses a rotating support plate and a rotating groove for rotational connection, and a chassis component and a chassis slot for rotational connection. This ensures that the entire structure remains stable when the clamping arms are securing the main wheel hub, and remains stable even when the drive motor drives the chassis components to rotate, thereby tilting the wheel hub. It achieves the purpose of tilting the wheel hub at high speed and with precision, reducing waiting time during operation and improving work efficiency.

A chassis component 18 is provided at the bottom of the motor fixing component 17. A rotating connecting shaft 19 is provided on the side of the chassis component 18 away from the motor fixing component 17. A drive motor 20 is provided on the side of the rotating connecting shaft 19 away from the chassis component 18. A fixing plate 21 is provided on the side of the drive motor 20 away from the rotating connecting shaft 19. A fixing post 22 is provided on the side of the fixing plate 21 near the drive motor 20. A chassis slot 23 is provided on the side of the fixing post 22. The fixed column 22 has a rotating support plate 24 at the end away from the fixed plate 21. A hub 25 is installed on one side of the clamping arm 1. The clamping arm 1 and the clamping arm 2 are rotatably connected by a support shaft 3. The support shaft 3 is welded to a rotating groove 4, and the rotating groove 4 is rotatably connected to the rotating support plate 24. The clamping arm 1 and the connecting rod 6 are rotatably connected by a connecting shaft 5. The threaded rod 7 is welded to the connecting rod 6. The clamping arm 2 and the connecting rod 9 are rotatably connected by a connecting shaft 8. The threaded rod 10 is welded to the connecting rod 9. The rotating cylinder 11 is threadedly connected to the threaded rod 7 and the threaded rod 10. The gear 12 meshes with the gear 14. The gear connecting shaft 15 is welded and rotatably connected to the power motor 16. The gear fixing member 13 is rotatably connected to the rotating drum 11 and rotatably connected to the gear connecting shaft 15. The power motor 16 is fixedly connected to the motor fixing member 17. The chassis member 18 is welded to the gear fixing member 13 and the motor fixing member 17. The chassis member 18 is welded to the rotating connecting shaft 19 and rotatably connected to the chassis slot 23. The rotating connecting shaft 19 is rotatably connected to the drive motor 20. The drive motor 20 is fixedly connected to the fixing plate 21. The fixing column 22 is welded to the fixing plate 21 and the chassis slot 23.Furthermore, the fixed column 22 is slidably connected to the rotating support plate 24, and the first clamping arm 1 is engaged with the wheel hub 25, as are the second clamping arm 2.

[0025] The implementation principle of this embodiment is as follows: When the tilting mechanism for producing the car wheel hub 25 is in use, because the power motor 16 is rotatably connected to the gear 14 and the gear 14 meshes with the gear 12, starting the power motor 16 will cause the gear 12 to rotate, thereby driving the drum to rotate. Because the drum is threadedly connected to the threaded rod 7 and the threaded rod 10, and the threaded directions of the threaded rod 7 and the threaded rod 10 are opposite, the rotation of the drum will cause the threaded rod 7 to move away from the threaded rod 10. The threaded rod 7 is welded to one side of the connecting rod 6 and the threaded rod 10 is welded to one side of the connecting rod 9, which will cause the connecting rod 6 to move away from the connecting rod 9. Also, because the connecting rod 6 is rotatably connected to the clamping arm 1 and the connecting rod 9 is rotatably connected to the clamping arm 2, the clamping arm 1 can move away from the clamping arm 2. When the wheel hub 25 is placed in the middle position between the clamping arm 1 and the clamping arm 2, starting the power motor 16 in the opposite direction will cause the clamping arm 1 to move closer to the clamping arm 2, thereby clamping the wheel hub 25. When the wheel hub 25 needs to be rotated, the drive motor 20 drives the chassis component 18 to rotate through the rotating connecting shaft 19. Since the power motor 16, gear 12 and gear 24 are all fixed to the chassis component 18 through the fixing parts, the clamping arms 1 and 2 can rotate the wheel hub 25. After the operation is completed, the power motor 16 can be started to release the clamping arms 1 and 2 from the wheel hub 25, thereby removing the wheel hub 25.

[0026] Compared with the prior art, the present invention has the following advantages: This wheel hub production tilting mechanism uses a drive motor 20 to rotate the chassis component 18, which in turn rotates the clamping arms 1 and 2, achieving the tilting of the wheel hub 25. This improves upon the previous method where operators had to repeatedly tilt the wheel hub 25 during production. The design employs a rotating support plate 24 rotatably connected to the rotating groove 4, and a chassis component 18 rotatably connected to the chassis slot 23. This ensures that the entire structure remains stable when the clamping arms are securing the main wheel hub 25, and also remains stable when the drive motor 20 rotates the chassis component 18, thus tilting the wheel hub 25. This high-speed and precise tilting mechanism reduces waiting time and improves work efficiency.

[0027] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
