[0002] In the automotive manufacturing and related industries, wheel hubs are crucial components. The dimensional and shape accuracy of the wheel hub's inner bore directly affects the assembly precision and performance of the wheel hub with other parts, thus impacting vehicle safety, stability, and comfort. For example, the spacing between the inner bore plates is one of the key dimensions in the wheel hub unit's clearance design; only precise measurement can ensure that the clearance value of the wheel hub unit is within the theoretical design range.

[0003] Currently, there are many shortcomings in the industry's inspection of wheel hub inner bores. Traditional inspection methods often involve operators using tools such as vernier calipers and micrometers. However, due to the limitations of the wheel hub's inner bore size and structure, using these traditional tools is extremely inconvenient, and the measurement accuracy is difficult to meet requirements. Furthermore, interference between the measuring tool and the inner bore can easily occur during the measurement process, leading to time-consuming and laborious measurements, and potentially introducing human error, resulting in inaccurate measurement results.

[0004] With the continuous development of the automotive industry, the production scale of wheel hubs is expanding, placing higher demands on the accuracy, efficiency, and automation of wheel hub inner hole inspection.

Detailed Implementation

[0026] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0027] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] This embodiment provides a wheel hub inner hole inspection machine, which enables rapid inspection of the inner hole of the wheel hub. During this process, no manual operation is required, and no traditional measuring tools are needed, which effectively improves the inspection efficiency of the inner hole of the wheel hub. Furthermore, the wheel hub inner hole inspection machine achieves automated processing, reduces human operation errors, and improves the inspection accuracy of the inner hole of the wheel hub.

[0029] Combination Figures 1 to 4 As shown, the wheel hub inner hole inspection machine of this embodiment includes a frame 10 and a measuring unit 20. The measuring unit 20 is disposed on the frame 10 and inspects the inner hole of the wheel hub.

[0030] In this embodiment, the measuring unit 20 includes a first platform 21, a second platform 22, a third platform 23, a three-jaw cylinder 24, and a displacement sensor 25. The first platform 21, the second platform 22, and the third platform 23 are arranged in sequence from far to near relative to the surface of the frame 10. A wheel hub is mounted on the first platform 21. The three-jaw cylinder 24 is mounted on the second platform 22. A measuring block 30 is provided on the top of the three-jaw cylinder 24. The measuring block 30 is located inside the inner hole of the wheel hub. The displacement sensor 25 is mounted on the third platform 23 to determine the displacement distance of the measuring block 30. When it is necessary to detect the inner hole of the wheel hub, the wheel hub is placed on the first platform 21, and the three-jaw cylinder 24 drives the measuring block 30 to move within the inner hole of the wheel hub. The displacement distance of the measuring block 30 is determined by the displacement sensor 25, thereby realizing the detection of the inner hole of the wheel hub.

[0031] Specifically, in this embodiment, the first platform 21 is provided with a through hole 211, and the measuring block 30 is positioned corresponding to the through hole 211 so that the measuring block 30 protrudes from the surface of the first platform 21. The through hole 211 is composed of three receiving cavities 40, which form a trident-shaped hole structure. There are three measuring blocks 30, which correspond one-to-one with the three receiving cavities 40. In this embodiment, three measuring blocks 30 are used to tighten the inner hole of the wheel hub, which is beneficial for detecting the inner hole of the wheel hub and improving the detection accuracy.

[0032] like Figure 3 As shown, in this embodiment, the first platform 21 and the second platform 22, as well as the second platform 22 and the third platform 23, are connected by fixed posts 50. Under the action of the fixed posts 50, the first platform 21, the second platform 22, and the third platform 23 are fixedly connected. The first platform 21, the second platform 22, the third platform 23, the three-jaw cylinder 24, and the displacement sensor 25 are coaxially arranged to improve the detection effect of the wheel hub inner hole.

[0033] Combination Figure 1 and Figure 2 As shown, in this embodiment, the frame 10 is provided with an oil receiving tray 60, which is located below the first platform 21. The frame 10 is provided with an air blowing head 70, which corresponds to the position of the measuring block 30. The frame 10 is provided with a through-beam photoelectric sensor 80, which corresponds to the position of the first platform 21 to determine the presence of the wheel hub. Before placing the wheel hub, the air blowing head 70 is used to blow air onto the measuring block 30 to clean the impurities and debris on the measuring block 30 for subsequent testing operations. The presence of the through-beam photoelectric sensor 80 allows it to detect the presence of the wheel hub after it is placed on the first platform 21, facilitating subsequent operations. The presence of the oil receiving tray 60 allows for the collection of cutting fluid flowing out of the wheel hub, preventing the cutting fluid from dripping directly.

[0034] In this embodiment, the wheel hub inner hole inspection machine also includes a protective cover 90, which is located between the first platform 21 and the third platform 23. The protective cover 90 protects the three-jaw cylinder 24 and improves the inspection accuracy.

[0035] In actual use, the wheel hub inner hole inspection machine of this embodiment uses an external robotic arm to place the wheel hub on the first platform 21. The piston rod of the rear three-jaw cylinder 24 drives the measuring block 30, causing the measuring block 30 to be tightened in the inner hole of the wheel hub. The displacement sensor 25 monitors the movement distance of the piston rod, and the piston rod drives the measuring block 30. Therefore, based on the movement distance of the piston rod, the displacement distance of the measuring block 30 can be calculated, and then the diameter of the center hole of the wheel hub can be calculated. After the measurement is completed, the data is uploaded to the PLC, and the wheel hub is judged to be qualified according to the preset dimensions and tolerances.

Rather, the foregoing description of the configurations will provide those skilled in the art with an enabling description for implementing the described techniques.
