Turning temperature measurement system based on microstructure optical fiber sensing

Abstract

The invention discloses a turning temperature measurement system based on microstructure optical fiber sensing, and belongs to the technical field of temperature measurement. Fixing and adjustment ofa microstructure optical fiber probe in a tool micropore are achieved through the cooperation of a tool, a tool bar, an optical fiber clamp and a conduction optical fiber, the microstructure optical fiber probe and the conduction optical fiber collect heat radiation spontaneously generated by the tool at a high temperature and conduct the heat radiation to an optical and photoelectric conversion unit, the optical and photoelectric conversion unit splits and filters an optical signal and performs photoelectric conversion to generate a voltage signal, and a data acquisition unit acquires the voltage signal and converts the voltage signal into a temperature signal. Therefore, the temperature measurement system realizes in-situ online measurement of a cutting temperature of the turning tool under the condition that a machine tool system is not modified on a large scale, and is convenient to apply, stable in structure and high in practicability. Meanwhile, the microstructure optical fiber probe can enhance collection of thermal radiation optical signals, thereby enhancing the signal-to-noise ratio of the temperature measurement system, and improving the temperature measurement accuracy.
