Abstract

The invention discloses a temperature measuring device and method for graphene drilling machining. The device comprises a base and a workbench mounted on the base; the workbench is provided with a drilling assembly and a temperature measuring assembly; the drilling assembly comprises a machining main shaft, a main shaft fixing frame, a drill bit, an adjusting table and a clamping device mounted on the adjusting table; the temperature measuring assembly comprises an annular mounting frame, heat radiation receiving instruments, a converter and a signal processor; the annular mounting frame is fixedly mounted on the machining main shaft; a plurality of telescopic rods are arranged at the bottom of the annular mounting frame in the circumferential direction at intervals. Temperature values of multiple points of the drill bit or a workpiece are measured at different angles and different distances through the multiple heat radiation receiving instruments at the same time, and then the temperature conditions in a drilling area are obtained after the temperature values of the multiple points are processed, so that measurement of the three-dimensional temperature field in the drilling area is accurately completed.

Description

technical field [0001] The invention relates to the field of temperature measurement, in particular to a temperature measurement device and method for graphene drilling. Background technique [0002] Graphene is a new material with a single-layer two-dimensional honeycomb lattice structure that is stripped from graphite materials and composed of carbon atoms. Graphene has relatively good toughness and strength, and graphene is gradually used in various industries. In the processing and production of graphene, it is often necessary to drill holes in graphene. In the process of drilling graphene composite materials, due to the contact between the drill bit and the workpiece and chips, the friction work is generated through the action of friction, and the shear work generated by chips Most of it is converted into cutting heat energy, which makes the cutting temperature rise. The cutting temperature not only affects the performance of the workpiece and the drill bit, the wear ...
