Description

Technical Field

[0001] This utility model relates to the field of wheel hub inspection technology, and in particular to a wheel hub inner support fixing device and wheel hub inspection equipment. Background Technology

[0002] With the rapid development of the automotive industry towards intelligence and customization, wheel hubs, as core components bearing the dynamic performance of vehicles, are facing increasingly stringent manufacturing precision and defect detection standards. Even minor flaws on wheel hubs, such as cracks and porosity, can lead to catastrophic failures under complex operating conditions, placing extremely high demands on non-destructive testing of wheel hubs. Traditional manual visual inspection or single-angle scanning techniques are no longer sufficient to meet these high-precision inspection requirements. While machine vision imaging technology can reveal defects in wheel hubs, its inspection efficiency and coverage largely depend on the wheel hub's attitude adjustment capabilities, presenting a new challenge to the design of wheel hub positioning structures.

[0003] Traditional wheel positioning devices typically use grippers to hold wheel hubs, which suffer from poor compatibility and difficulty in stably gripping different models and sizes of wheel hubs. Furthermore, the positioning and clamping process can easily cause secondary damage such as scratches and bumps to the wheel hub surface, affecting its appearance and quality. For example, on automotive wheel hub production lines, traditional positioning devices may require frequent replacement or adjustment to adapt to different types of wheel hubs, increasing operational complexity and reducing production efficiency. In addition, for wheel hubs with specially treated surfaces or complex curved surfaces, the rigid contact method of traditional positioning devices may lead to uneven localized stress, posing a risk of secondary damage to the wheel hub.

[0008] The second abutting support portion is configured to move away from the first abutting support portion along a second direction, so that both the first and second abutting support portions are adapted to abut against the ring wall, and / or the second abutting support portion is configured to move closer to the first abutting support portion along a second direction, so that both the first and second abutting support portions are adapted to be spaced from the wheel hub, the second direction being perpendicular to the first direction.

[0009] In some embodiments, the hub inner support fixing device includes a drive assembly and a transmission assembly. The first abutment support and the second abutment support are both connected to the drive assembly through the transmission assembly. The drive assembly is configured to drive the second abutment support away from or towards the first abutment support in a second direction.

[0010] In some embodiments, the transmission assembly includes a first connector and a second connector, a first abutting support portion is connected to one end of the first connector along a second direction, and a second abutting support portion is connected to one end of the second connector away from the first abutting support portion along the second direction.

[0011] The drive assembly includes a rotating member, a first connecting member and a second connecting member respectively connecting opposite sides of the rotating member. The rotating member rotates circumferentially about a first direction so that the first abutting support and the second abutting support move closer to or further away from each other.

[0012] In some embodiments, a first abutting support portion is rotatably connected to a first connector, a second abutting support portion is rotatably connected to a second connector, both the first connector and the second connector are rotatably connected to a rotating member, the extension directions of the first connector and the second connector are parallel, along a direction perpendicular to the extension direction of the first connector, the rotating member is sandwiched between the first connector and the second connector, and the hub inner support fixing device includes a limiting member, the limiting member being used to restrict the movement of the first connector and the second connector along a second direction.

[0013] In some embodiments, the limiting member includes a guide rail and a first slider and a second slider that are slidably connected to the guide rail, the first slider being connected to a first abutting support and the second slider being connected to a second abutting support.

[0014] In some embodiments, the drive assembly includes a drive cylinder connected to a rotating member, the drive cylinder being used to drive the first rotating member to rotate about a first direction.

[0015] In some embodiments, the drive assembly includes a pressure sensor connected to the drive cylinder, and the pressure sensor is used to determine the pressure of the drive cylinder.

[0016] In some embodiments, the surface of the first abutting support portion for abutting the wheel hub is configured as an arc surface, and the surface of the second abutting support portion for abutting the wheel hub is configured as an arc surface; and / or,

[0017] The first abutment support part is elastic, and the second abutment support part is elastic.

[0018] A second aspect of this utility model provides a wheel hub inspection device, including the wheel hub inner support fixing device as described above, and the wheel hub moving device further includes:

[0019] A rotating assembly is connected to a hub inner support fixing device to drive the hub inner support fixing device to rotate circumferentially about a first direction;

[0020] A lifting assembly is connected to a rotating assembly, and the lifting assembly can drive the rotating assembly and the hub inner support fixing device to move along a first direction;

[0021] The detection system is suitable for detecting wheel hubs fitted with inner support fixing devices.

[0022] A third aspect of this utility model provides a wheel hub inspection method for use in the aforementioned wheel hub inspection equipment. The wheel hub inspection method includes:

[0023] The lifting assembly drives the inner support fixing device of the wheel hub to pass into the wheel hub;

[0024] Both the first and second abutting support parts abut against the inner wall of the wheel hub rim;

[0025] The rotating component drives the inner support fixing device of the wheel hub to rotate, thereby causing the wheel hub to rotate;

[0026] The detection system acquires information about the wheel hub.

[0027] According to the above embodiments, the beneficial effects of this utility model are:

[0028] The wheel hub inner support fixing device of this utility model includes a first abutting support portion and a second abutting support portion. Both the second abutting support portion and the first abutting support portion are adapted to extend into the wheel hub along a first direction, and the second abutting support portion is movably connected to the first abutting support portion. Specifically, the second abutting support portion is configured to move away from or towards the first abutting support portion along a second direction. Moving away from the first abutting support portion achieves the effect of the first and second abutting support portions abutting against the inner side of the wheel rim wall, thereby achieving wheel hub positioning. Moving closer to the first abutting support portion achieves the separation and interlocking of the first and second abutting support portions and the wheel hub, thereby releasing the restriction on the wheel hub. Furthermore, when wheel hub positioning is not required, the proximity of the second and first abutting support portions allows the wheel hub inner support fixing device to occupy less space, improving space utilization.

[0029] It is understood that the hub internal support fixing device of this application abuts against the hub from inside the hub, achieving a fixed connection with the hub in a spreading manner. Since the distance between the first abutment support and the second abutment support is adjustable, this application can adapt to hubs of different sizes and diameters, thus exhibiting better compatibility. Specifically, when it is necessary to adapt the component to a larger diameter rim, the second abutment support can move away from the first abutment support along a second direction perpendicular to the first direction; conversely, when facing a smaller diameter rim, the second abutment support moves closer to the first abutment support along the second direction.

[0030] Furthermore, compared to the existing technology that clamps the wheel hub for positioning, this application only abuts against the wheel hub from the inside, resulting in more balanced force distribution and better protection, effectively preventing damage to the wheel hub. Moreover, since the first and second abutting supports can be close to each other, the wheel hub inner support fixing device of this application can be brought together when not in operation or when needing to pass through small spaces, reducing the space occupied by the wheel hub inner support fixing device and improving space utilization.

[0031] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0051] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0052] 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.

[0053] The following is for reference. Figures 1 to 14 This describes the wheel hub inner support fixing device 100, wheel hub testing equipment, and wheel hub testing method according to embodiments of the present invention. (Refer to...) Figure 1 as well as Figures 2 to 6 The wheel hub inner support fixing device 100 of this utility model includes a first abutting support portion 110 and a second abutting support portion 120. Both the second abutting support portion 120 and the first abutting support portion 110 are adapted to extend into the wheel hub along a first direction, and the second abutting support portion 120 is movably connected to the first abutting support portion 110. For ease of understanding, this description uses the axial direction of the wheel hub to be tested when fixed to the wheel hub inner support fixing device 100 as the first direction. Specifically, the second abutting support portion 120 is configured to move away from or towards the first abutting support portion 110 along a second direction. The second abutting support portion 120 moving away from the first abutting support portion 110 achieves the effect of the first abutting support portion 110 and the second abutting support portion 120 abutting against the inner side of the rim ring wall, thereby achieving wheel hub positioning. The second abutting support portion 120 moving towards the first abutting support portion 110 achieves the separation and distancing of the first abutting support portion 110, the second abutting support portion 120, and the wheel hub, thereby releasing the restriction on the wheel hub. Furthermore, when there is no need to position the wheel hub, the second abutment support 120 and the first abutment support 110 are close to each other, which can reduce the space occupied by the wheel hub inner support fixing device 100 and improve space utilization.

[0054] Reference Figure 2 , Figure 5 and Figure 6The hub internal support fixing device 100 of this application abuts against the hub from inside the hub, achieving a fixed connection with the hub in a spreading manner. Since the distance between the first abutment support 110 and the second abutment support 120 is adjustable, this application can adapt to hubs of different sizes and diameters, thus exhibiting better compatibility. This application ensures that both abutment supports effectively abut against the rim wall by adjusting the distance between the two abutment supports, thereby firmly fixing the hub. Specifically, when it is necessary to adapt the component to a larger diameter rim, the second abutment support 120 can move away from the first abutment support 110 along a second direction perpendicular to the first direction; conversely, when facing a smaller diameter rim, the second abutment support 120 moves closer to the first abutment support 110 along the second direction.

[0055] Furthermore, compared to the existing technology that clamps the wheel hub for positioning, this application only abuts against the wheel hub from the inside, resulting in more balanced force distribution on the wheel hub and better protection, effectively preventing damage to the wheel hub. Moreover, since the first abutting support 110 and the second abutting support 120 can be brought close together, the wheel hub inner support fixing device 100 can be moved closer together when not in operation or when needing to pass through small spaces, thereby reducing the space occupied by the wheel hub inner support fixing device 100 and improving space utilization.

[0056] It is understood that in some embodiments, the wheel hub inner support fixing device 100 includes multiple structures for supporting the wheel hub. For example, in addition to the first abutting support part 110 and the second abutting support part 120, there are also a third abutting support part, a fourth abutting support part, a fifth abutting support part, etc. Multiple abutting support parts with abutting effect are designed to apply the force for fixing the wheel hub more evenly, so that the force on the wheel hub is more balanced and the force on a certain point of the wheel hub is weaker, thus providing better protection for the wheel hub.

[0057] In this application, the second direction is any direction perpendicular to the first direction. The second abutting support 120 is opposite to the first abutting support 110 along the second direction, which is intended to reflect the opening action of the first abutting support 110 and the second abutting support 120, which abut against the inner side of the rim ring wall in an opening manner. Therefore, regarding the third abutting support, fourth abutting support, and fifth abutting support in the above embodiments, they all abut against the inner side of the rim ring wall in an opening manner, and the direction in which they are opposite to each other is not a single direction. It can be understood as an opening action that spreads outward from the hub axis. Furthermore, for example, when the hub inner support fixing device 100 includes the first abutting support 110, the second abutting support 120, and the third abutting support, in order to balance the force on the hub, the three abutting support parts are usually arranged around the rim at a uniformly spaced angle. At this time, when the three abut against the rim from the center position, the state of their opposites is not along a single direction. In summary, the second direction introduced in this application is merely for ease of description and should not be limited to the fact that when the hub inner support fixing device 100 is opened to position the hub, they can only move away from each other in a single direction.

[0058] It is understandable that the first abutting support part 110 and the second abutting support part 120 do not necessarily move in opposite directions when they abut against the wheel hub. The first abutting support part 110 and the second abutting support part 120 can apply the component forces of the forces acting on the wheel hub in opposite directions to ensure that the wheel hub is positioned.

[0059] In some embodiments, the first abutment support 110 and the second abutment support 120 integrate small spring mechanisms to achieve adaptive pressure adjustment when contacting the rim. Specifically, the spring mechanism is installed inside the contact surface of the abutment support and arranged along the direction of contact between the abutment support and the rim. When the abutment support opens to contact the rim, the spring mechanism can adjust the pressure in real time according to the rigidity of the rim and the contact area, ensuring that the contact force between the abutment support and the rim is both strong enough and does not damage the hub due to excessive pressure. The elastic coefficient of the spring mechanism can be optimized according to the material and size of the hub to adapt to hubs of different specifications. In addition, the dynamic adjustment capability of the spring mechanism allows the hub internal support fixing device 100 to automatically adapt and maintain the best fixing effect when facing rims of different diameters, further improving the compatibility and protection of the component. (Refer to...) Figure 2 , Figure 5 and Figure 6In some embodiments, the hub inner support fixing device 100 includes a drive assembly 130 and a transmission assembly 140. The first abutment support 110 and the second abutment support 120 are both connected to the drive assembly 130 via the transmission assembly 140. The drive assembly 130 is configured to drive the second abutment support 120 away from or towards the first abutment support 110 in a second direction. The drive assembly 130 can be configured as a motor, hydraulic cylinder, or other forms. In some embodiments, the drive assembly 130 can also be a rocker arm, which the user manually rotates to bring the first and second abutment parts closer together or further apart. The transmission component 140 serves as an intermediate structure connecting the first abutment support 110 and the second abutment support 120 to the drive component 130. It has a certain rigidity and can transmit the driving effect of the drive component 130 to the first abutment support 110 and the second abutment support 120. This modular connection method is beneficial to the design of the first abutment support 110 and the second abutment support 120, making the shape and connection method of the first abutment support 110 and the second abutment support 120 more flexible.

[0060] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments, the transmission assembly 140 includes a first connector 141 and a second connector 142. A first abutting support portion 110 is connected to one end of the first connector 141 along a second direction, and a second abutting support portion 120 is connected to one end of the second connector 142 opposite to the first abutting support portion 110 along the second direction. The first abutting support portion 110 and the second abutting support portion 120 face opposite sides. When the drive assembly 130 drives the first abutting support portion 110 and the second abutting support portion 120 to move away from each other, they can achieve the effect of abutting against the inner side of the rim ring wall.

[0061] Reference Figure 2 , Figure 5 and Figure 6In some embodiments, the drive assembly 130 includes a rotating member 131, with a first connecting member 141 and a second connecting member 142 respectively connected to opposite sides of the rotating member 131. The rotating member 131 rotates circumferentially about a first direction, causing the first abutting support portion 110 and the second abutting support portion 120 to move closer to or further away from each other. For example, the rotating member 131 can be an approximately rhomboid rotating block, which is relatively flat, with the first connecting member 141 and the second connecting member 142 rotatably connected to opposite corners of the rhomboid rotating block that are farther apart. In this embodiment, the way the first abutting support portion 110 and the second abutting support portion 120 move further away from each other can be understood as a form of rubbing them apart, with the two connected by the rotating member 131. Specifically, the outline of the intermediate connector is circular, and the first connector 141 and the second connector 142 are connected to opposite sides of the intermediate connector in the radial direction. When the circular outline rolls, the first connector 141 and the second connector 142 will move in opposite directions, thereby driving the first abutting support 110 and the second abutting support 120 to abut against the inner side of the rim ring wall.

[0062] Regarding the movement of the first connecting member 141 and the second connecting member 142 in opposite directions under the drive of the rotating member 131, specifically, in some embodiments, the rotating member 131 can be a gear, and the first connecting member 141 and the second connecting member 142 are equipped with racks that mesh with the gear. The gear rotates to drive the rack to move in a straight line. Since the first connecting member 141 and the second connecting member 142 are located on opposite sides of the gear in the radial direction, the first connecting member 141 and the second connecting member 142 move in opposite directions.

[0063] It is understandable that, in some embodiments, the design of the first connector 141 and the second connector 142 can be improved to further enhance the flexibility and reliability of the system. For example, the first connector 141 and the second connector 142 can be replaced with telescopic connectors. Such telescopic connectors consist of multiple adjustable-length segments, whose total length can be adjusted as needed to more precisely control the position of the abutment support. Furthermore, sensors can be integrated inside the connectors to monitor their position changes in real time and provide feedback to the control system for timely parameter adjustments. Telescopic connectors can adapt to a wider variety of wheel hub sizes and shapes, enhancing the versatility and applicability of the equipment.

[0064] Reference Figure 2 , Figure 5 and Figure 6In some embodiments, the first abutting support 110 is rotatably connected to the first connecting member 141, and the second abutting support 120 is rotatably connected to the second connecting member 142. Both the first connecting member 141 and the second connecting member 142 are rotatably connected to the rotating member 131. The extending directions of the first connecting member 141 and the second connecting member 142 are parallel. Along a direction perpendicular to the extending direction of the first connecting member 141, the rotating member 131 is sandwiched between the first connecting member 141 and the second connecting member 142. The hub inner support fixing device 100 includes a limiting member 150, which restricts the movement of the first connecting member 141 and the second connecting member 142 along a second direction. It is understood that without a limiting design, when the rotating member 131 rotates circumferentially, the first connecting member 141 and the second connecting member 142 will also adjust their direction with the axial rotation of the rotating member 131. That is, the first abutting support 110 and the second abutting support 120 will rotate circumferentially along the rotation of the rotating member 131, and will not be able to abut against the wheel rim. The first abutting support 110, the first connecting member 141, the second abutting support 120, the second connecting member 142, and the rotating member 131 are all rotatably connected, allowing for a high degree of freedom. When the rotating member 131 rotates, it is only necessary to restrict the first connecting member 141, the second connecting member 142, or the first abutting support 110 and the second abutting support 120 to move around the circumference of the rotating member 131. This allows the first abutting support 110 and the second abutting support 120 to slide relative to the limiting member 150 during the rotation of the rotating member 131, and to move closer to or together with each other in opposite directions.

[0065] Regarding the rotational connections between the first abutting support 110 and the first connecting member 141, the second abutting support 120 and the second connecting member 142, the first connecting member 141 and the rotating member 131, and the second connecting member 142 and the rotating member 131, in some embodiments, their rotational connections are achieved through pin-hole fitting. The length direction of the pin is parallel to a first direction. The first abutting support 110 can rotate relative to the first connecting member 141 about the first direction, the second abutting support 120 can rotate relative to the second connecting member 142 about the first direction, the first connecting member 141 can rotate about the first direction relative to the rotating member 131, and the second connecting member 142 can rotate about the first direction relative to the rotating member 131. Through the action of the limiting member 150, when the rotating member 131 rotates, the first connecting member 141 and the second connecting member 142 slide in opposite directions due to the obstruction of the limiting member 150, so that the first abutting support 110 and the second abutting support 120 abut against the inner surface of the rim ring wall.

[0066] Reference Figure 2 , Figure 5 and Figure 6In some embodiments, the hub inner support fixing device 100 includes a limiting member 150, which includes a guide rail 151 and a first slider 160 and a second slider 170 respectively slidably connected to the guide rail 151. A first abutting support 110 is connected to the first slider 160 via a first connector 141, while a second abutting support 120 is connected to the second slider 170 via a second connector 142. This structural design allows the first abutting support 110 and the second abutting support 120 to move along the direction of the guide rail 151, thereby achieving actions that bring them closer together or further apart. The guide rail 151 provides a stable linear motion path, ensuring the accuracy and stability of the first abutting support 110 and the second abutting support 120 when adjusting their spacing.

[0067] The design of guide rail 151 reduces sliding friction. By using a low-friction coefficient material to manufacture both the rail and the slider, the friction between them is reduced, improving sliding efficiency. When drive assembly 130 drives rotating component 131 to rotate, first connector 141 and second connector 142 respectively drive first slider 160 and second slider 170 to move along guide rail 151, achieving precise position adjustment of first abutment support 110 and second abutment support 120. This not only ensures adaptability to rims of different sizes but also ensures stable clamping of the wheel hub during high-precision testing.

[0068] Understandably, in some embodiments, the guide rail 151 can employ magnetic levitation technology instead of the traditional mechanical contact design. For example, electromagnets are embedded inside the guide rail 151 and the slider, and the magnetic field strength is adjusted by controlling the current intensity, thereby suspending the slider at a certain distance above the track, reducing the wear and resistance caused by traditional sliding. In this way, even under high-frequency operation, a long service life and high-precision position adjustment capability can be maintained.

[0069] Understandably, in some embodiments, to further enhance the stability and reliability of the limiting member 150, multiple sensors, such as position sensors or speed sensors, can be installed on the guide rail 151. These sensors monitor the position and movement speed of the slider in real time and feed the data back to the control system. Once an anomaly is detected, the system can immediately take corrective measures to ensure that the first abutment support 110 and the second abutment support 120 are always in the correct relative position, thereby improving the safety and accuracy of the entire hub positioning process.

[0070] Reference Figure 2 , Figure 5 and Figure 6In some embodiments, the drive assembly 130 includes a drive cylinder connected to the rotating member 131. The drive cylinder uses pressure generated by compressed air to push a piston rod, thereby driving the rotating member 131 to rotate about a first direction. The pressure of the drive cylinder is adjustable, meaning that the opening between the first abutment support 110 and the second abutment support 120 can be adjusted as needed to accommodate different wheel hub sizes. The drive cylinder utilizes the incompressibility of liquids and the characteristics of hydraulic transmission to convert the input force over a small area into an output force over a large area, effectively overcoming friction and other resistance between mechanical structures. Furthermore, the response speed of the drive cylinder is faster than that of a motor, improving work efficiency.

[0071] In some embodiments, the drive cylinder is equipped with a pressure sensor to monitor internal pressure changes in real time. When a pressure value exceeding a set range is detected, the system automatically adjusts the cylinder's operating state to prevent equipment damage or hub deformation caused by excessive pressure. This feature is crucial for ensuring long-term stable operation of the equipment and also enhances operational safety.

[0072] It is understood that in some embodiments, in addition to pressure sensors, temperature and humidity sensors can be added to monitor changes in the environment surrounding the drive cylinder. Environmental factors can affect the cylinder's performance and can easily impact wheel hubs in the same indoor environment as the wheel hub inner support fixing device 100 of this application. For example, high temperatures may cause seal aging, and excessive humidity may cause corrosion of internal components. By integrating these additional sensors, early warnings can be provided and corresponding protective measures can be taken, extending the equipment's service life while improving the system's reliability and safety.

[0073] In some embodiments, the drive assembly 130 is a pressure sensor. A drive cylinder is connected to the rotating member 131 and is used to drive the first rotating member 131 to rotate about a first direction. The pressure sensor can be connected to the drive cylinder, or it can be directly or indirectly connected to any of the components that interact with the hub, such as the first abutment support 110, the second abutment support 120, the first connector 141, the second connector 142, or the rotating member 131. The pressure sensor is used to monitor pressure changes in the drive cylinder. Specifically, for example, when the pressure sensor is connected to the drive cylinder, the pressure sensor monitors the internal pressure of the cylinder in real time and adjusts the cylinder input pressure through a feedback mechanism to ensure that the first abutment support 110 and the second abutment support 120 can move smoothly and accurately. For example, when it is necessary to increase the distance between the first abutment support 110 and the second abutment support 120, the drive cylinder increases the pressure, causing the rotating member 131 to rotate clockwise; conversely, it rotates counterclockwise to decrease the distance between them. This design not only ensures operational accuracy but also improves the safety and reliability of the equipment.

[0074] It is understood that in some embodiments, electronic pressure sensors can be used in addition to traditional mechanical pressure sensors. Electronic pressure sensors offer higher accuracy and faster response times, providing quicker feedback on pressure changes within the cylinder. This allows the entire system to react in a shorter time, improving its dynamic performance, and is particularly suitable for high-frequency operation.

[0075] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments, the surfaces of both the first abutment support 110 and the second abutment support 120 are configured as arc surfaces to better conform to the inner wall shape of the rim. The arc design increases the contact area, reduces local stress concentration, and helps protect the rim from damage. Furthermore, the first abutment support 110 and the second abutment support 120 may also possess elastic properties, allowing them to adapt to rims of different sizes and shapes during clamping, providing a more flexible and reliable positioning effect.

[0076] The selection of elastic materials is crucial. They must ensure sufficient rigidity to maintain structural stability while also possessing a degree of flexibility to adapt to different contact surfaces. Common choices include highly elastic materials such as rubber, silicone, PU leather, and PA materials. These materials not only have good compressive strength but also excellent wear resistance and corrosion resistance. The design principle of elastic structures lies in utilizing the material's inherent elasticity and restoring force to effectively clamp rims of different sizes, avoiding damage caused by hard contact.

[0077] It is understood that in some embodiments, the arc surfaces of the first abutment support 110 and the second abutment support 120 can be composed of multiple small arc surfaces with adjustable angles. Each small arc surface can be independently adjusted to adapt to different rim shapes. For example, some specially designed rims may have irregular inner wall contours. By adjusting the angles of each small arc surface, the first abutment support 110 and the second abutment support 120 can be perfectly fitted to the inner wall of the rim, ensuring the accuracy and stability of positioning. Furthermore, the first abutment support 110 consists of a main body and multiple rotatable small blocks with arc surfaces. When the first abutment support 110 applies pressure to the inner side of the rim ring wall, the small blocks with arc surfaces rotate relative to the main body of the first abutment support 110 to better fit the shape of the inner wall of the rim, thereby providing better protection for the rim. The design of the second abutment support 120 is similar and will not be described in detail here.

[0078] Understandably, in some embodiments, the elastic portions of the first abutment support 110 and the second abutment support 120 can be made of composite materials, i.e., a layer of elastic material is coated onto a metal matrix. The metal matrix provides the necessary support strength, while the elastic material is responsible for cushioning and adapting to rims of different shapes. This composite structure combines the advantages of both, maintaining sufficient rigidity to withstand large clamping forces while possessing good flexibility to adapt to complex working conditions. Furthermore, the application of composite materials improves the overall durability of the components and reduces maintenance costs.

[0079] It is understood that in some embodiments, the first abutment support 110 and the second abutment support 120 may be made of elastic material themselves, or they may be connected separately to an elastic structure, such as a spring, to achieve elasticity.

[0080] Reference Figures 1 to 13 The second aspect of this utility model provides a wheel hub inspection device. (Refer to...) Figure 1 In some embodiments, the wheel hub inspection equipment includes a wheel hub inner support fixing device 100, a rotating assembly 200, a lifting assembly 300, and an inspection system. (See also...) Figures 2 to 6 The wheel hub inner support fixing device 100 includes a first abutting support portion 110 and a second abutting support portion 120, which are connected to the drive assembly 130 via a transmission assembly 140. The wheel hub inner support fixing device 100 is adapted to extend into the inside of the wheel hub, and achieves a stable clamping of the wheel hub by adjusting the positions of the first abutting support portion 110 and the second abutting support portion 120.

[0081] Reference Figure 13 The rotating assembly 200 is connected to the inner hub support fixing device 100 and is used to drive the inner hub support fixing device 100 to rotate around a first direction. The rotating assembly 200 typically consists of a motor, a reducer, and a rotating platform 210. The rotating platform 210 supports the inner hub support fixing device 100, the motor provides power, and the reducer adjusts the speed to adapt to different working requirements. When a full-range inspection of the wheel hub is required, the rotating assembly 200 can drive the inner hub support fixing device 100 and the wheel hub it holds to rotate 360 ​​degrees.

[0082] Of course, in some embodiments, to facilitate the rotation of the wheel hub, the wheel hub detection device also includes rollers. When the rotating assembly 200 drives the wheel hub inner support fixing device 100 to rotate, if the first abutment support part 110 and the second abutment support part 120 position the wheel hub, the wheel hub will also rotate accordingly. In this case, the rollers are added so that the wheel hub rolls on the rollers when it rotates, thereby facilitating the rotation of the wheel hub.

[0083] Reference Figure 1 and Figures 7 to 12The lifting assembly 300 is connected below the rotating assembly 200 and is used to drive the entire device to move in a first direction. The lifting assembly 300 typically employs a hydraulic or electric push rod design, which can precisely control the distance of ascent and descent, ensuring that the hub inner support fixing device 100 accurately penetrates into the hub. Furthermore, the lifting assembly 300 can adjust the height of the hub as needed during the inspection process, facilitating the operation of the inspection system. For example, the lifting assembly 300 includes a lifting inner cylinder 310, a lifting outer cylinder 320, and a lifting platform 330. The lifting outer cylinder 320 is connected to the lifting inner cylinder 310 via a gear and rack mechanism. The end of the lifting outer cylinder 320 is connected to the lifting platform 330, which supports the rotating assembly 200 and the hub inner support fixing device 100. The lifting outer cylinder 320 slides relative to the lifting inner cylinder 310 to drive the hub inner support fixing device 100 to extend into the hub in the first direction.

[0084] Of course, in some embodiments, in order to facilitate the movement of the lifting assembly 300, the wheel hub detection device also includes a moving assembly, which is used to drive the lifting assembly 300, the rotating assembly 200, and the wheel hub inner support fixing device 100 to a specific position, such as below the wheel hub axis. Then the lifting assembly 300 drives the wheel hub inner support fixing device 100 to move upward so that the first abutting support part 110 and the second abutting support part 120 extend into the inner side of the rim ring wall.

[0085] The inspection system is positioned above or around the wheel hub to acquire various information about the hub, including dimensional measurements and surface defect detection. The system utilizes laser scanners, cameras, or other sensor technologies to collect and analyze data in real time, thereby assessing the quality of the wheel hub. In some embodiments, the inspection system can also integrate machine vision technology, using high-resolution cameras and image processing software to perform detailed inspections of the wheel hub surface. For example, by taking photographs of the wheel hub from various angles and using algorithms to identify any minute cracks or deformations, this non-contact inspection method not only improves efficiency but also reduces human error. Vision systems are already well-established in the prior art and will not be elaborated upon here. This application, through the rotating component 200 and the wheel hub inner support fixing device 100, allows the wheel hub to rotate one or more times around a first direction, facilitating a more comprehensive inspection of the wheel hub by the inspection system.

[0086] Understandably, in some embodiments, 3D scanning technology can be introduced into the inspection system to further improve inspection accuracy. A 3D scanner can quickly generate a 3D model of the wheel hub, and by analyzing this data, it is possible to more accurately determine whether the wheel hub has manufacturing deviations or damage. This method is particularly suitable for wheel hubs with complex shapes, such as lightweight alloy wheels used in high-performance sports cars.

[0087] A third aspect of this utility model provides a wheel hub inspection method, referring to... Figure 14 In some embodiments, the wheel hub detection method includes the following steps:

[0088] S101: The lifting assembly 300 drives the inner support fixing device 100 of the wheel hub to pass into the wheel hub;

[0089] S103: Both the first abutting support part 110 and the second abutting support part 120 abut against the inner wall of the wheel hub rim;

[0090] S105: The rotating component 200 drives the inner support fixing device 100 of the wheel hub to rotate, so as to make the wheel hub rotate;

[0091] S107: The detection system acquires information about the wheel hub.

[0092] Specifically, firstly, the lifting assembly 300 drives the inner hub support fixing device 100 to move upward until it penetrates into the inside of the wheel hub. At this time, the first abutting support part 110 and the second abutting support part 120 are in a retracted state to facilitate smooth entry into the inner space of the wheel hub.

[0093] Next, the drive assembly 130 is activated, causing the first abutment support 110 and the second abutment support 120 to unfold along the second direction until both are tightly fitted against the inner wall of the rim. Because the first abutment support 110 and the second abutment support 120 are elastic and have an arc-shaped surface, they can effectively adapt to rims of different diameters and profiles, ensuring a good clamping effect.

[0094] Subsequently, the rotating component 200 begins operation, driving the inner support fixing device 100 and the clamped wheel hub to rotate around the first direction. The rotation speed can be adjusted according to specific testing requirements. In this way, the testing system can comprehensively acquire information about the wheel hub from multiple angles.

[0095] Finally, the inspection system is activated, using various sensors (such as laser rangefinders and cameras) to conduct a detailed inspection of the wheel hub. For example, it can scan the wheel hub surface to detect scratches, dents, or other defects; it can also assess its manufacturing precision by measuring changes in the inner and outer diameters of the wheel hub. All collected data is transmitted to a central processing unit for comprehensive analysis, ultimately generating a detailed inspection report.

[0096] Understandably, in some embodiments, the detection system may also be equipped with an automatic fault diagnosis module. This module, based on a comparison of pre-set standard parameters and actual test results, can automatically identify potential problems with the wheel hub and propose corresponding repair suggestions. For example, if a stress concentration point is detected in a certain area of ​​the wheel hub, it will suggest strengthening the structural strength of that area to prevent future breakage risks.

[0097] Understandably, in some embodiments, to meet the high-efficiency testing requirements of large-scale production environments, wheel hub testing equipment can be configured with a multi-station system. Multiple stations are equipped with independent wheel hub internal support fixing devices 100, rotating components 200, lifting components 300, and testing systems, enabling multiple wheel hubs to be tested simultaneously. This not only significantly improves work efficiency but also reduces the time cost required for testing a single wheel hub. Furthermore, the stations can be interconnected via a network to achieve data sharing and unified management.

[0098] Reference Figures 1 to 14 Furthermore, in some embodiments, the wheel hub detection method of this application is as follows:

[0099] After the wheel hub is in position, it is conveyed to the top of the rotating assembly 200 of the wheel hub detection equipment. The servo motor of the lifting assembly 300 drives the lifting helical gear to rotate counterclockwise, thereby causing the inner cylinder of the lifting assembly 300 to rise. The rise of the inner cylinder of the lifting assembly 300 causes the rotating assembly 200 and the wheel hub inner support fixing device 100 to rise. After the wheel hub inner support fixing device 100 rises to a preset height, the cylinder of the drive assembly 130 drives the rotating block and the rotating block connecting plate to rotate counterclockwise, thereby driving the connecting parts of the transmission assembly 140 to move to both sides with the slider until the first abutting support part 110 and the second abutting support part 120 of the wheel hub inner support fixing device 100 abut against the inner wall of the wheel hub, and the cylinder stops running. At this time, the first abutting support part 110 and the second abutting support part 120 firmly abut against the inner wall of the wheel hub, realizing the positioning of the wheel hub.

[0100] Subsequently, the servo motor of the rotating assembly 200 drives the rotating platform 210 and the connecting plate of the rotating platform 210 to rotate, thereby causing the inner support fixing device 100 of the hub and the hub to rotate together. After the hub rotates to a preset number of revolutions, the servo motor stops driving and resets to the initial zero angle. At this time, the cylinder of the drive assembly 130 drives the rotating block and the rotating block connecting plate to rotate clockwise, thereby driving the connecting part of the transmission assembly 140 to move inward with the slider, returning to the initial state, and the cylinder stops running. Finally, the servo motor of the lifting assembly 300 drives the lifting helical gear to rotate clockwise, causing the inner cylinder of the lifting assembly 300 to descend, so that the rotating assembly 200 and the inner support fixing device 100 of the hub descend to the initial position.

[0101] In summary, this application can be adapted to various wheel sizes, provides good protection for the wheel, and has high work efficiency and comprehensive testing capabilities.
