Abstract

The invention discloses a detecting device and detecting method for measuring the outer diameter and the inner diameter of the wheel of a motor train. The device mainly comprises a wheel vertical detection platform, a horizontal detection platform, a fine reference support device, a coarse reference support device, a transportation platform, a rotary driving device. Four laser displacement sensors, including laser displacement sensors A and B installed on a crescent board tail end IV and laser displacement sensors C and D installed on the wheel vertical detection platform III, horizontally move a [delta]L and a [delta]X in the radial direction of the wheel of the motor train respectively. The scanning measured values in each length unit of the four laser displacement sensors are stored in an acquisition card. Then the maximum value of the measured data of each laser displacement sensor is selected to be compared with standard data to calculate the outer diameter and the inner diameter of the wheel. Then, the above operation is performed after a wheel rotary driving device is rotated by a certain angle. After measurement is performed three times, average values are acquired to be used as the measured values of the outer diameter and the inner diameter of the wheel.

Description

technical field [0001] The invention relates to a measurement and detection device and detection method for the outer diameter and inner diameter of a motor vehicle wheel, is an online detection system, and belongs to the field of machine vision Background technique [0002] With the development of my country's railway industry, the speed of high-speed trains continues to increase. Although it brings convenience to people's travel, it also brings great challenges to the safe operation of railways. As a key component in the moving process of the train, the wheel is in direct contact with the track, which directly determines the safety and quality of the vehicle. Wheels are used for the running and steering of vehicles on the track, and the key dimensions of the outer diameter of the wheels are directly related to the safety of the train. The rapid development of railway speed and the high-density operation of vehicles have accelerated the wear of wheels. Therefore, higher r...
