Specific embodiment
Combined with specific embodiments below, the content of the utility model is described in further detail:
In order to reach the purpose of this utility model, the utility model cycle wheel system for detecting roundness is shown in Fig. 1
Structural schematic diagram.The cycle wheel system for detecting roundness is by shaft 1, rack 3, data acquisition module 4 and information processing
Several parts such as terminal 6 are constituted, and central shaft rod 1 passes through the central axes of cycle wheel 2, and is fixedly connected with cycle wheel 2；It should
Shaft 1 is fixedly installed in rack 3, and can rotate relatively freely.Shaft 1 need to have preferable intensity and rigidity, to bicycle
Before wheel 2 is formally detected, it must ensure correctness, the consistency and stability of 1 relative position of shaft.In cycle wheel 2
Surface is equipped with the data acquisition module 4 for measuring its circularity.Above-mentioned data acquisition module 4 is connected with the information processing terminal 6.Data
Acquisition module 4 includes range sensor.Range sensor is clamped by the mechanical arm being separately provided, and is avoided as much as certainly
