[0002] As an important component of automobiles, the quality of wheel hubs directly affects the driving safety of vehicles. Therefore, during the manufacturing process of wheel hubs, strict requirements are imposed on the inspection items and inspection frequency of dimensions. Among them, the runout inspection of the bead seat of the wheel hub is an important inspection item. If the runout of the bead seat of the wheel hub is out of tolerance, the vehicle will easily experience abnormal shaking during driving, affecting the driving experience of the entire vehicle and even threatening driving safety.

[0003] At present, for the monitoring of the runout of the bead seat of the hub, a special runout meter is required for detection during routine inspections. The wheel hub needs to be manually moved to the runout meter for detection, which is cumbersome and has low detection efficiency. With the continuous improvement of production efficiency and the sharp increase in output, relying on a special runout meter to detect the runout of the bead seat of the hub can no longer meet the monitoring requirements of a higher detection frequency. The low inspection frequency makes it difficult to timely discover the quality defects of excessive hub runout, and it is impossible to effectively curb the continuous production of defective products. It is easy to produce batches of waste products, which is not conducive to product quality control.

[0004] Based on this, it is an urgent problem to develop a lightweight hub inspection platform that is easy to operate to realize the quick detection of hub runout, so as to improve the detection efficiency and monitoring frequency, timely discover quality defects, and curb the production of defective products.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Thanks to the simple structure and lightweight design of the measuring platform, the measuring platform can be easily moved to a position convenient for detection during use, and the detection operation can be carried out after it is placed stably. During measurement, the wheel hub to be detected is placed on the turntable 3, and the wheel hub is manually moved so that the wheel hub rotates stably relative to the support column under the support of the turntable 3. The measuring head fixed on the column 4 is adjusted to align with the measurement position, and the measurement data of the measuring head is read to complete the wheel hub runout detection. This embodiment is easy to operate, has high detection efficiency, and reduces the labor intensity of operators.

[0022] As a preferred embodiment, a positioning mandrel 31 is provided on the turntable 3 corresponding to the center hole of the wheel hub, and the positioning mandrel 31 cooperates with the axis hole of the center hole of the wheel hub.
