Confirmation of the wheel rim hole machining dimensions is also done manually by calculation and input. This method carries risks such as measurement errors, transmission failures, calculation errors, and data entry errors. Furthermore, it requires specialized personnel for operation, which presents both quality risks and wastes labor costs. Utility Model Content

[0027] like Figure 1 and Figure 2As shown, in this embodiment, the wheel measuring device includes a base frame 10, a clamping structure 20, and a measuring structure 30. The base frame 10 supports the wheel 1. The clamping structure 20 is disposed on the base frame 10 and includes a driving member 21, a transmission assembly 22, a first clamping member 23, and a second clamping member 24. The first clamping member 23 and the second clamping member 24 are disposed opposite to each other and can move closer or further apart. When the first clamping member 23 and the second clamping member 24 move closer together, they can clamp the wheel 1. The transmission assembly 22 is connected to both the first clamping member 23 and the second clamping member 24. The driving member 21 drives the transmission assembly 22 to drive the first clamping member 23 and the second clamping member 24 to move closer or further apart. The measuring structure 30 includes a lifting structure 31 and a measuring element 32 disposed on the lifting structure 31. The lifting structure 31 has a raised position and a retracted position. When the lifting structure 31 is in the raised position, the measuring element 32 enters the axle hole of the wheel 1. When the lifting structure 31 is in the retracted position, the measuring element 32 is located below the wheel 1.

[0028] Using the technical solution of this embodiment, the base frame 10 can support the wheel 1. A clamping structure 20 is disposed on the base frame 10. The clamping structure 20 includes a driving member 21, a transmission assembly 22, a first clamping member 23, and a second clamping member 24. The transmission assembly 22 is connected to the first clamping member 23 and the second clamping member 24. The driving member 21 can drive the transmission assembly 22 to move the first clamping member 23 and the second clamping member 24 closer together or further apart. The measuring structure 30 includes a lifting structure 31 and a measuring member 32. The lifting structure 31 has a raised position and a retracted position. When the lifting structure 31 is in the raised position, the measuring member 32 can enter the axle hole of the wheel 1. With the above configuration, wheel 1 is placed on base frame 10. Drive component 21 drives transmission assembly 22, which in turn drives first clamping component 23 and second clamping component 24 to move relative to each other, thereby enabling first clamping component 23 and second clamping component 24 to clamp wheel 1. At this time, lifting structure 31 moves from retracted position to raised position, allowing measuring component 32 to enter the axle hole of wheel 1. After entering the axle hole, measuring component 32 can measure the axle hole, thus improving measurement accuracy. Therefore, the technical solution of this embodiment effectively solves the problem of measurement errors in wheel measuring devices in related technologies.

[0029] Specifically, by precisely controlling the coordinated action of the clamping structure 20 and the measuring structure 30, this wheel measuring device can effectively improve the measurement efficiency and accuracy of the wheel axle hole. This wheel measuring device can significantly reduce the errors and time of manual measurement, and can quickly and accurately obtain relevant data of the wheel axle hole, thereby improving the inspection efficiency and production quality of the production line.

[0030] like Figure 1 and Figure 2As shown, in this embodiment, the measuring structure 30 further includes a rotating component 33, which is disposed between the lifting structure 31 and the measuring component 32. The rotating component 33 enables the measuring component 32 to rotate, thereby allowing the measuring component 32 to perform 360° measurements.

[0031] Specifically, the addition of the rotating component 33 enables the measuring component 32 to scan the wheel axle hole from all directions, further improving the comprehensiveness and accuracy of the measurement. The 360-degree rotation of the rotating component allows for the acquisition of omnidirectional data of the wheel axle hole, which is particularly important for detecting parameters such as the depth, shape, and size of the axle hole.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the measuring component 32 is a laser scanner. The aforementioned laser scanner is capable of scanning. Laser scanners are characterized by non-contact operation, high precision, and high speed, enabling them to quickly and accurately acquire three-dimensional data of wheel axle holes, making them suitable for applications requiring high-precision measurements. The use of a laser scanner not only avoids potential damage to the wheel caused by traditional contact measurements but also allows for the acquisition of high-precision three-dimensional data at millisecond-level speeds.

[0033] like Figures 2 to 5 As shown, in this embodiment, the transmission assembly 22 includes a rotating member 221, a first connecting rod 222, and a second connecting rod 223. The first end of the first connecting rod 222 is hinged to the rotating member 221, the second end of the first connecting rod 222 is hinged to the first clamping member 23, the first end of the second connecting rod 223 is hinged to the rotating member 221, and the second end of the second connecting rod 223 is hinged to the second clamping member 24. The driving member 21 drives the rotating member 221. When the rotating member 221 rotates, it can pull the first connecting rod 222 and the second connecting rod 223 to move, thereby pulling the first clamping member 23 and the second clamping member 24, thus clamping the wheel 1. This transmission assembly 22 design ensures the synchronous and stable movement of the first clamping member 23 and the second clamping member 24, making it suitable for wheel 1 positioning and measurement on automated production lines. Furthermore, this design ensures stable clamping of the wheel 1 during the measurement process, avoiding measurement errors caused by wheel 1 movement, and improving production efficiency and product quality.

[0034] like Figures 2 to 5 As shown, in this embodiment, the base frame 10 includes a first frame 11 and a second frame 12. The second frame 12 is located below the first frame 11. The first frame 11 supports the wheel 1. The clamping structure 20 is disposed on the second frame 12, and the first clamping member 23 and the second clamping member 24 extend above the first frame 11. The first frame 11 can support the wheel 1, thereby making the position of the wheel 1 more stable, while the second frame 12 can fix the clamping structure 20.

[0035] Specifically, this layered design not only ensures stable support for wheel 1, but also makes the layout of clamping structure 20 and measuring structure 30 more reasonable and the operation more convenient.

[0036] like Figures 2 to 5 As shown, in this embodiment, the rotating component 221 includes a rotating shaft 2211, a first connecting arm 2212, a second connecting arm 2213, and a third connecting arm 2214. All three connecting arms are connected to the rotating shaft 2211. The first and second connecting arms 2212 and 2213 are positioned opposite each other, and the third connecting arm 2214 is located below the second connecting arm 2213. The driving component 21 is hinged to the third connecting arm 2214. The first connecting arm 2212 is hinged to the first connecting rod 222, and the second connecting arm 2213 is hinged to the second connecting rod 223. This design of the rotating component 221 enables efficient and precise control of the first clamping component 23 and the second clamping component 24 by the driving component 21, reducing measurement errors caused by inaccurate positioning and improving the accuracy and reliability of the detection.

[0037] like Figures 2 to 5 As shown, in this embodiment, the first clamping member 23 includes a first moving member 231 and a plurality of first clamping posts 232. The plurality of first clamping posts 232 are spaced apart and all connected to the first moving member 231. The first connecting rod 222 is connected to the first moving member 231. The second clamping member 24 includes a second moving member 241 and a plurality of second clamping posts 242. The plurality of second clamping posts 242 are spaced apart and all connected to the second moving member 241. The second connecting rod 223 is connected to the second moving member 241. The design of the plurality of first clamping posts 232 and the plurality of second clamping posts 242 can evenly distribute the clamping force and prevent the wheel 1 from deforming during the clamping process. In actual operation, this uniform clamping force distribution can prevent wheel deformation caused by excessive local pressure, protecting the structure and performance of the wheel.

[0038] like Figures 2 to 5 As shown, in this embodiment, the wheel measuring device further includes a first guide member 41 and a second guide member 42. The first guide member 41 is disposed between the second frame 12 and the first clamping member 23, and the second guide member 42 is disposed between the second frame 12 and the second clamping member 24. The addition of the first guide member 41 and the second guide member 42 can ensure the straightness and stability of the first clamping member 23 and the second clamping member 24 during movement, and avoid measurement errors.

[0039] like Figures 2 to 5As shown, in this embodiment, the first frame 11 is provided with multiple rolling columns 111, which are spaced apart and whose axes are parallel. These multiple rolling columns 111 collectively support the wheel 1. This support method not only reduces friction when the wheel 1 is placed, protecting the wheel surface from damage, but also improves the positioning accuracy of the wheel 1. Specifically, the design of multiple rolling columns 111 provides a stable support surface, reduces friction between the wheel 1 and the first frame 11 when placed, protects the smoothness of the wheel surface, avoids damage, and simultaneously improves the positioning accuracy of the wheel.

[0040] like Figures 2 to 5 As shown, in this embodiment, the wheel measuring device further includes a pusher 50, which is movably mounted on the first frame 11. The pusher 50 facilitates the positioning and unloading of the wheel 1, improving operational convenience. In actual operation, the pusher 50 can accurately push the wheel 1 to the measurement position. After the measurement is completed, the wheel can be safely unloaded, saving operation time and improving operational safety.

[0041] The wheel measuring device in this embodiment supports the wheel via a base frame 10 and uses a clamping structure 20 to precisely fix the position of the wheel 1. Combined with the lifting and rotation of the measuring structure 30, it enables automated and high-precision measurement of the wheel 1's axle hole. Using a laser scanner as the measuring element 32 allows for rapid acquisition of three-dimensional data of the wheel axle hole, improving measurement efficiency and accuracy. Simultaneously, the first guide 41 and the second guide 42 ensure stable movement of the first clamping element 23 and the second clamping element 24, further enhancing measurement stability. The design of multiple rolling columns 111 not only supports the wheel 1 but also reduces friction during wheel placement, protecting the wheel 1 surface from damage. The pusher 50 facilitates wheel positioning and unloading, improving operational convenience. The overall design is compact, easy to operate, and suitable for measuring various wheel specifications, significantly improving the efficiency and accuracy of wheel inspection. Furthermore, the device has good scalability and upgradeability, allowing for adjustments to the type and parameters of the measuring element according to different measurement needs, such as replacing it with an ultrasonic scanner or optical measuring instrument, to adapt to a wider range of application scenarios.

[0043] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
