It plays a vital role in the maintenance and overhaul of railway vehicles. With the rapid development of railway transportation, the measurement accuracy requirements for the axle box wear plate position are getting higher and higher. Therefore, it is particularly important to develop an efficient and accurate special measuring tool for the axle box wear plate position. In China, with the continuous growth of the domestic economy and the acceleration of urbanization, the railway and rail transit industries have developed rapidly. This has led to a growing demand for accurate measurement of key components such as axle box wear plates. And with the rapid development of high-speed railways, heavy-load railways, and urban rail transit, higher requirements are placed on the accuracy of the axle box wear plate and the accuracy of the installation position. Therefore, more accurate and efficient special measuring tools are needed to meet these needs.
