Description

Technical Field

[0001] This invention relates to the field of automotive repair technology, specifically a wheel hub deformation straightening machine for cars. Background Technology

[0002] Wheel rim deformation is a common problem in automotive repair. It not only affects vehicle performance but can also pose safety hazards. Current wheel rim straightening techniques primarily rely on manual operation, using hand tools to correct the rim. However, this traditional method has several problems. First, the straightening effect is unstable; due to the lack of effective positioning and fixing devices, the wheel rim is prone to displacement during straightening, resulting in low accuracy. Second, manual straightening requires multiple workers to operate simultaneously—one holding the tools while others fix the rim—which increases labor costs and significantly reduces efficiency. Furthermore, manual straightening is physically demanding; prolonged operation can easily lead to operator fatigue, further affecting the straightening quality.

[0003] Among existing patented technologies, patent number 201811583672.4, entitled "A Correction Device for Automobile Wheel Hubs," provides a solution. This device, by setting a base, a correction unit, and a positioning unit, can improve the correction effect and efficiency to a certain extent. However, this device still has some limitations. For example, its correction process requires manual operation of multiple components, making operation complex and lacking automated control. Furthermore, although the positioning unit can fix the wheel hub, it cannot adjust the correction force and position in real time according to the deformation of the wheel hub during the correction process, resulting in a need to improve the correction effect. In summary, existing wheel hub correction devices still have shortcomings in terms of automation, correction accuracy, and work efficiency, and cannot meet the demands of the modern automotive repair industry for efficient and precise correction.

At the same time, the cylinders of the first hydraulic rod and the second hydraulic rod are connected to the oil tank.

[0015] Optionally, the hydraulic control console consists of multiple directional control valves, each used to control the connection or disconnection of the oil circuit or the switching of the oil flow direction.

[0016] Optionally, it also includes a control board, which is connected to the drive components and the hydraulic system for control; multiple casters are fixedly installed under the base.

[0017] (III) Beneficial Effects

[0018] This invention provides a wheel hub deformation straightening machine for cars, which has the following beneficial effects:

[0019] 1. This invention achieves automated wheel hub straightening by incorporating a driving component, an upper shaping component, and a lower shaping component. The driving component rotates the wheel hub, causing deformed areas of the rim to be pressed and rolled back into a circular shape by the pressing and lifting components during rotation. This automated straightening method not only improves straightening accuracy but also significantly increases straightening efficiency. Compared to traditional manual straightening, this invention can complete wheel hub straightening in a short time, reducing labor costs and improving work efficiency.

[0020] 2. The wheel hub deformation straightening machine of this invention adopts automated operation, requiring only one worker to complete the wheel hub straightening work. Compared with the traditional multi-person collaborative straightening method, it greatly reduces the manpower requirement. The operator does not need to hold tools for a long time for straightening; they only need to operate and monitor the equipment, avoiding fatigue and operational errors caused by long hours of high-intensity labor, thereby further improving the straightening quality and work efficiency. In addition, the equipment has a high degree of automation, is simple and easy to learn to operate, and has relatively low requirements for the professional skills of operators, further reducing labor and training costs.

[0021] 3. The hydraulic system design further enhances the stability and reliability of the straightening process. The hydraulic control console, through multiple directional control valves, can precisely control the connection, disconnection, or switching of oil flow direction, thereby achieving precise control of the pressing and lifting components. This precise control allows for real-time adjustment of the straightening force and position based on the wheel hub deformation, ensuring consistent straightening results.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments.

[0032] Please see Figures 1 to 6 The present invention provides a technical solution: a wheel hub deformation straightening machine for straightening the deformed rim on the wheel hub 23, including a base 1, a drive component for fixing and driving the wheel hub 23 to rotate, an upper shaping component, a lower shaping component, and a hydraulic system.

[0033] The drive component is used to fix the wheel hub 23 and drive it to rotate. The upper and lower shaping components are used to straighten the wheel hub 23. The hydraulic system provides power during straightening. The base 1 serves as the supporting foundation for the entire device, ensuring its stability.

[0034] A portal frame 3 is fixedly mounted on the base 1. The driving components include a drive shaft 26 and a first motor 24. The drive shaft 26 extends laterally through the side column of the portal frame 3 and is rotatably mounted to the side column of the portal frame 3. A wheel hub 23 is detachably mounted on the drive shaft 26. The first motor 24 is fixedly mounted on the portal frame 3 and is connected to the drive shaft 26. The first motor 24 drives the drive shaft 26 to rotate, and the first motor 24 drives the wheel hub 23 to rotate via the drive shaft 26.

[0035] The gantry frame 3 serves as the main support frame of the straightening machine, providing mounting positions for the drive components, upper shaping components, and lower shaping components. The first motor 24 is the power source for the drive components, providing power to the drive shaft 26 to rotate the hub 23. The hub 23, the object to be straightened, is detachably mounted on the drive shaft 26 for easy straightening operations. The center holes of the spokes of the hub 23 are fitted onto the drive shaft 26, ensuring stable rotation of the hub 23 during the straightening process.

[0036] The upper shaping component includes a first hydraulic rod 4 and a pressing assembly. The first hydraulic rod 4 is fixedly mounted on the top of the portal frame 3, and the pressing assembly is detachably mounted on the output shaft end of the first hydraulic rod 4. The first hydraulic rod 4 drives the pressing assembly to move up and down. The lower shaping component includes a second hydraulic rod 10 and a lifting assembly. The second hydraulic rod 10 is fixedly mounted on the portal frame 3, and the lifting assembly is detachably mounted on the output shaft end of the second hydraulic rod 10. The second hydraulic rod 10 drives the lifting assembly to move up and down.

[0037] The pressing component and the lifting component form a clamping position. The rim of the hub 23 is located in the clamping position. When the driving component drives the hub to rotate, the entire rim rotates in the circumferential direction. The deformed part of the rim is deformed after being crushed by the pressing component and the lifting component, so that the deformed part of the rim returns to the circular state.

[0038] The first hydraulic rod 4 drives the pressing assembly to move up and down, thereby pressing and straightening the rim of the wheel hub 23. The pressing assembly is used to press and straighten the rim of the wheel hub 23. The second hydraulic rod 10 drives the lifting assembly to move up and down, thereby lifting and straightening the rim of the wheel hub 23. The lifting assembly is used to lift and straighten the rim of the wheel hub 23. The pressing assembly and the lifting assembly form a clamping position, and the rim of the wheel hub is located in the clamping position. During the straightening process, the pressing assembly and the lifting assembly work together to press and straighten the deformed parts of the rim. Through the cooperation of the pressing assembly and the lifting assembly, straightening forces can be applied simultaneously from both the inner and outer sides of the rim, so that the deformed parts of the rim gradually return to a circular state during rotation.

[0039] Specifically, the drive components also include a sleeve 21 and a reducer 25. One end of the sleeve 21 is fixedly installed on the inner wall of the portal frame 3. The drive shaft 26 passes laterally through the sleeve 21 and the side column of the portal frame 3, and is rotatably installed with the sleeve 21. The reducer 25 is fixedly installed on the side column of the portal frame 3. The power output end of the first motor 24 is coaxially and fixedly connected to the power input end of the reducer 25. The power output end of the reducer 25 is coaxially and fixedly connected to one end of the drive shaft 26.

[0040] The sleeve 21 supports the drive shaft 26 and ensures its stability during rotation, preventing radial displacement of the drive shaft 26. The reducer 25 reduces the speed of the first motor 24 and increases the torque, thereby providing a stronger driving force to the drive shaft 26. When the first motor 24 starts, it transmits power to the reducer 25, which then transmits the power to the drive shaft 26, causing the drive shaft 26 to rotate.

[0041] More specifically, the drive component also includes a limiting disc 20 and a large nut 19. The limiting disc 20 is fitted onto the outer wall of the end of the drive shaft 26 away from the reducer 25, and the limiting disc 20 is fixedly connected to the drive shaft 26. The large nut 19 is threadedly connected to the end of the drive shaft 26 away from the reducer 25. The limiting disc 20 and the large nut 19 form a mounting position, and the center hole of the spoke of the hub 23 is fitted onto the drive shaft 26, with the spoke of the hub 23 located at the mounting position.

[0042] The limiting plate 20 is used to fix the spokes of the wheel hub, ensuring that the wheel hub 23 will not loosen or shift during the straightening process, and providing a stable support surface for the wheel hub. The large nut 19, through its internal thread, engages with the external thread at the end of the drive shaft 26, and when tightened, it can generate sufficient clamping force to firmly fix the spokes of the wheel hub 23 onto the drive shaft 26.

[0043] Specifically, the upper shaping component also includes a support plate 5, which is fixedly installed on the output shaft end of the first hydraulic rod 4. A first sliding groove is provided on the support plate 5. The pressing assembly includes a connecting rod 6, a limiting ring 7, a first handle 8, and a pressing element. The lower end of the connecting rod 6 is fixedly installed with the pressing element. A limiting ring 7 is sleeved on the upper outer wall of the connecting rod 6, and the two are longitudinally slidably connected. The connecting rod 6 is laterally slidably installed in the first sliding groove of the support plate 5. The first handle 8 is threaded onto the upper end of the connecting rod 6. The first handle 8 can be manually rotated to move closer to or away from the pressing element.

[0044] The support plate 5 has a first sliding groove, which guides the lateral movement of the pressing assembly, allowing it to be flexibly disassembled and adjusted according to the size and deformation of the hub 23. The limiting ring 7 engages with the connecting rod 6 within the first sliding groove of the support plate 5, enabling the pressing assembly to move up and down with the support plate 5. The first handle 8 is used to tighten or loosen the threads by rotation. When the first handle 8 is tightened on the connecting rod 6, it presses down, and through the limiting ring 7, clamps and fixes the entire pressing assembly to the support plate 5. When the first handle 8 is rotated to loosen, the entire pressing assembly gradually separates from the support plate 5.

[0045] More specifically, the pressing component adopts either the pressing wheel 9 or the pressing plate 18. The pressing plate 18 is arc-shaped, and the arc curvature of the side wall where the center of the pressing plate 18 is located is consistent with the arc curvature of the outer side wall of the rim. This design can ensure that the pressing plate 18 and the rim are in closer contact, thus improving the correction effect.

[0046] The pressing roller 9 is a type of pressing component used to roll and press the rim of the hub 23 for straightening. The pressing roller is typically made of wear-resistant materials, such as hard alloy or high-strength steel, to ensure it can withstand significant pressure without deformation during straightening. The outer surface of the pressing roller 9 is precision-machined to ensure a smooth and flat contact surface with the rim, reducing damage to the rim during straightening. As the hub 23 rotates, the pressing roller 9 continuously rolls and presses the deformed parts of the rim, gradually restoring it to a circular shape.

[0047] The pressing plate 18 is another form of pressing component, used to press and straighten the rim of the hub 23. The pressing plate 18 is typically made of high-strength materials, such as aluminum alloy or high-strength steel, to ensure it can withstand significant pressure without deformation during straightening. During straightening, the pressing plate 18, driven by the first hydraulic rod 4, moves closer to the rim of the hub 23, pressing down on the deformed areas of the rim. As the hub 23 rotates, the pressing plate 18 continuously slides and rolls over the deformed areas of the rim, gradually restoring it to a circular shape.

[0048] Specifically, the lower shaping component also includes an L-shaped fixing plate 11, the upper end of which is fixedly installed to the output shaft end of the second hydraulic rod 10. The lifting assembly includes a square tube 12, a second rotating shaft 13, a second handle 14, and a lifting member. The square tube 12 is sleeved on the end of the L-shaped fixing plate 11 away from the second hydraulic rod 10, and both the square tube 12 and the L-shaped fixing plate 11 have limit holes. The second handle 14 is fixedly connected to one end of the second rotating shaft 13. The second rotating shaft 13 passes through the limit holes on the square tube 12 and the L-shaped fixing plate 11, and is inserted into both the square tube 12 and the L-shaped fixing plate 11. The lifting member is fixedly installed on the upper surface of the square tube 12.

[0049] The L-shaped fixing plate 11 is used to fix and support the lifting assembly, ensuring its stability and accuracy during operation. As the second hydraulic rod 10 moves up and down, the L-shaped fixing plate 11 drives the entire lifting assembly to move up and down. During the correction process, the second hydraulic rod 10 drives the L-shaped fixing plate 11 to move up and down, which in turn drives the square tube 12 and the lifting component to move up and down as a whole. The square tube 12 is fitted onto the L-shaped fixing plate through its inner hole, and a stable connection is formed between the square tube and the L-shaped fixing plate through the insertion of the second rotating shaft. By inserting and removing the second handle 14, the operator can adjust the position of the second rotating shaft 13, thereby fixing or loosening the lifting assembly, and simultaneously adjusting the lateral position of the entire lifting assembly. This design allows the position of the lifting assembly to be flexibly adjusted according to the size and deformation of the hub 23.

[0050] Driven by the second hydraulic rod 10, the lifting component moves closer to the rim of the hub 23 and lifts the deformed parts of the rim. As the hub rotates, the lifting component continuously rolls over the deformed parts of the rim, gradually restoring them to a circular shape.

[0051] More specifically, the lifting component adopts one of the lifting wheel 15 and the lifting plate 17. The upper surface of the lifting plate 17 is arc-shaped, and the arc curvature of the upper surface of the lifting plate 17 is consistent with the arc curvature of the inner wall of the rim. This design can ensure that the lifting plate 17 has a tighter contact with the rim and reduce damage to the rim during the straightening process.

[0052] The lifting wheel 15 is a type of lifting component used to lift and straighten the rim of the hub 23. The lifting wheel 15 is typically made of wear-resistant materials, such as hard alloy or high-strength steel, to ensure it can withstand significant pressure without deformation during straightening. The outer surface of the lifting wheel 15 is usually precision-machined to ensure a smooth and flat contact surface with the rim, reducing damage to the rim during straightening. During straightening, driven by the second hydraulic rod 10, the lifting wheel 15 moves closer to the rim of the hub 23, lifting the deformed parts of the rim. As the hub 23 rotates, the lifting wheel 15 continuously rolls and presses the deformed parts of the rim, gradually restoring it to a circular shape.

[0053] The lifting plate 17 is another type of lifting component, used to lift and straighten the rim of the wheel hub 23. During the straightening process, driven by the second hydraulic rod 10, the lifting plate 17 moves closer to the rim of the wheel hub 23 and lifts the deformed parts of the rim. As the wheel hub 23 rotates, the lifting plate 17 continuously slides and rolls the deformed parts of the rim, gradually restoring it to a circular state.

[0054] Specifically, the hydraulic system includes an oil tank, a hydraulic pump 22, a main oil supply pipe, and a hydraulic control console 16. The hydraulic pump 22 is fixedly mounted on the side column of the portal frame 3. The oil inlet of the hydraulic pump 22 is connected to the oil tank. The inlet of the main oil supply pipe is fixedly mounted and connected to the oil outlet of the hydraulic pump 22. The outlet of the main oil supply pipe is fixedly mounted and connected to the hydraulic control console 16. The hydraulic control console 16 is connected to the cylinders of the first hydraulic rod 4 and the second hydraulic rod 10 through two branch oil supply pipes. Simultaneously, the cylinders of the first hydraulic rod 4 and the second hydraulic rod 10 are connected to the oil tank. The hydraulic control console 16 consists of multiple directional control valves, each used to control the connection, disconnection, or switching of the oil flow direction.

[0055] The oil tank stores hydraulic oil, providing sufficient fluid to the hydraulic system and ensuring its normal operation. The hydraulic control console 16 is the control center of the hydraulic system, used to control the flow direction, pressure, and volume of the hydraulic fluid, achieving precise control of the hydraulic rods. The hydraulic pump 22 pressurizes the hydraulic oil in the tank and delivers it to the hydraulic control console 16, providing power to the first hydraulic rod 4 and the second hydraulic rod 10. The first hydraulic rod 4 and the second hydraulic rod 10 are the actuators of the hydraulic system, used to drive the lifting and lowering movement of the pressing and jacking components, enabling the straightening operation of the wheel hub.

[0056] During the straightening process, hydraulic pump 22 draws hydraulic oil from the oil tank, pressurizes it, and delivers it to hydraulic control console 16 through the main oil pipeline. Under manual or electronic operation, hydraulic control console 16 controls the flow of hydraulic fluid via a directional control valve, distributing the oil to the cylinders of the first hydraulic rod 4 and the second hydraulic rod 10. Under the pressure of the hydraulic fluid, the first hydraulic rod 4 and the second hydraulic rod 10 drive the pressing and lifting components to move up and down, pressing and lifting the wheel rim for straightening. Through the control of hydraulic control console 16, the hydraulic rods can flexibly adjust the positions of the pressing and lifting components according to the deformation of the wheel rim, ensuring that the straightening force is evenly distributed on the deformed parts of the rim, improving the consistency and reliability of the straightening effect.

[0057] Specifically, the wheel hub deformation straightening machine also includes a control board, which is connected to the drive components and the hydraulic system. Multiple casters 2 are fixedly installed below the base 1. The control board uses a programmable logic controller (PLC) or a microcontroller, and contains logic control programs and timing control programs to automate the control of the drive components and the hydraulic system, and to adjust parameters during the automate control process. The control board is electrically connected to the first motor 24 and the hydraulic pump 22. When the directional control valve in the hydraulic control console 16 is a solenoid valve, the control board can also be electrically connected to the solenoid valve to control the connection, disconnection, or switching of the oil flow direction via electrical control. The control principle and control parameters of the control board will not be elaborated further.

[0058] The control board is the core component of the automated control system of the wheel hub deformation straightening machine, used to centrally control the drive components and hydraulic system. The control board contains logic control programs and timing control programs, which automatically control the actions of the drive components and hydraulic system according to preset straightening processes and operating procedures. The casters 2 enhance the mobility of the straightening machine, facilitating its movement within the maintenance area.

[0059] During the correction process, the operator inputs correction parameters and operating commands through the control panel. The control panel automatically controls the operation of the first motor 24 and the hydraulic pump 22 according to preset logic and timing control programs. The first motor 24 starts, stops, or adjusts its speed according to the control panel's commands, driving the transmission shaft 26 to rotate, which in turn rotates the hub 23. The hydraulic pump 22 starts, stops, or adjusts its output pressure and flow according to the control panel's commands, delivering hydraulic oil to the hydraulic control console 16. The hydraulic control console 16, according to the control panel's commands, controls the flow of hydraulic fluid through a directional control valve, achieving the lifting and lowering action of the hydraulic rod, driving the pressing and lifting components to perform the correction operation.

[0060] During use, in the correction process, the drive component drives the hub 23 to rotate, and the entire rim rotates in the circumferential direction. The first hydraulic rod 4 and the second hydraulic rod 10 adjust the height positions of the pressing component and the lifting component respectively according to the deformation of the hub 23.

[0061] The pressing assembly and the lifting assembly respectively press the deformed parts from the outside and inside of the rim. The pressing assembly applies pressure to the outer wall of the rim through the pressing wheel 9 or the pressing plate 18, while the lifting assembly applies a lifting force to the inner wall of the rim through the lifting wheel 15 or the lifting plate 17.

[0062] Through precise control of the hydraulic system, the pressing and lifting components can adjust the correction force and position in real time according to the degree of deformation of the wheel hub 23, ensuring the consistency and stability of the correction effect.

[0063] As the hub 23 rotates, the deformed parts of the rim are continuously rolled by the pressing and lifting components, gradually returning to a circular state, thus completing the correction operation.
