Mecanum wheel outer circumference contour detection device and detection method

The invention belongs to the technical field of diameter dimension detection, and relates to a Mecanum wheel outer circumference contour detection device and detection method. The lifting hydraulic cylinder drives the Mecanum wheel to descend, the servo motor and the digital vernier caliper collect data, the servo motor drives the Mecanum wheel to rotate around the clockwise direction by more than 10 circles, and data collection is stopped. The lifting hydraulic cylinder drives the Mecanum wheel to ascend, and the swing hydraulic cylinder drives the Mecanum wheel to rotate by 90 degrees and then stops. According to the invention, the radius size of the Mecanum wheel can be detected under a rated load, the size in a use state is detected, and the method has more guiding significance for production and use; compared with the prior art, the detection method has the advantages that the detection data is more, the detection accuracy is higher, unqualified Mecanum wheels are prevented from entering the assembly pro
