Optical measuring device for locomotive wheel set

Abstract

The invention discloses an optical measurement device for a locomotive wheelset, and belongs to the mechanical measurement field. Up to now, detection and diagnosis of a vehicle wheelset in China still stays at the manual measurement stage, and wheel rotation and wheelset parameter recording during the detection process are also completed manually. As manual measurement is not only tedious, but also has high labor intensity (measuring one group of wheelset by two people needs 20 minutes) and the measuring tools (a clamp, a ruler and the like) are old-fashioned, the manual measurement error cannot be eliminated. The optical measurement device for a locomotive wheelset includes a pedestal, a hydraulic lifting mechanism, backing rollers, a Y-axis slide rail, a Z-axis slide rail, a rotation test base, a white light confocal displacement sensor, an industrial control computer for data processing and analysis, and corresponding data analysis processing software. The optical measurement device for a locomotive wheelset can measure each geometric sense parameter of the locomotive wheelset through the white light confocal displacement sensor so as to realize the high-precision and intelligent detection item of the locomotive wheelset, perform data analysis and processing, and provide a detection report.

Description

technical field [0001] The invention relates to the field of mechanical measurement, in particular to an optical measurement system for a locomotive wheel set, which is a white light confocal non-contact intelligent automatic measurement system. Background technique [0002] The equipment imported from abroad is not only expensive, but also adopts traditional vision, displacement measurement or laser scanning distance measurement methods, which cannot meet the measurement accuracy requirements of the wheel set shafting; at the same time, the adaptability to the site environment is poor, and it is very sensitive to vibration and temperature fluctuations. , many parameters simply cannot meet the existing wheel set detection accuracy requirements. There are differences between the foreign railway system and our country's railway system, and the materials, specifications and dimensions of the wheelset are also different. Therefore, it is not yet ripe to use imported equipment to...

[0002] The equipment imported from abroad is not only expensive, but also adopts traditional vision, displacement measurement or laser scanning distance measurement methods, which cannot meet the measurement accuracy requirements of the wheel set shafting; at the same time, the adaptability to the site environment is poor, and it is very sensitive to vibration and temperature fluctuations. , many parameters simply cannot meet the existing wheel set detection accuracy requirements

There are differences between the foreign railway system and our country's railway system, and the materials, specifications and dimensions of the wheel sets are also different. Therefore, it is not yet ripe to use imported equipment to test our country's wheel sets.
