DEVICE FOR GRINDING TEMPERATURE ONLINE DETECTION AND PHASE CHANGE HEAT TRANSFER NANOFLUID GRINDING

摘要

A device for grinding temperature online detection and phase change heat transfer nanofluid grinding comprises a housing (11), a grinding device, a power device, a transmission device, a control module, a temperature measuring module and a speed and torque measuring module. The grinding device is mounted at the front end of the housing (11), and the power device, the transmission device, the control module, the temperature measuring module and the speed and torque measuring module are mounted inside the housing (11). The grinding device is connected with the power device by means of the transmission device, the temperature measuring module is connected with the grinding device and the control module respectively, the speed and torque measuring module is arranged on one side of the transmission device, and the speed and torque measuring module and the power device are both connected with the control module. A phase change heat transfer nanofluid grinding head is used in the grinding device; heat produced during the grinding is dissipated by means of continuous evaporation, condensation and reflux of the nanofluid; the temperature gets lowered to reduce secondary injury to the patient. A fluorescent fiber temperature sensor is used in the temperature measuring module, and a reflected photoelectric sensor is used in the speed and torque measuring module; consequently, the removal of pathological bone and the service life of the grinding head are controlled conveniently and accurately in a closed-loop manner.
