Abstract

The invention discloses a temperature measuring device and method for graphene drilling, including a base and a workbench installed on the base, the workbench is provided with a drilling assembly and a temperature measuring assembly, the drill The cutting assembly includes a processing spindle, a spindle fixing frame, a drill bit, an adjusting table, and a clamping device installed on the adjusting table. The temperature measurement assembly includes a ring mounting frame, a heat radiation receiver, a converter, and a signal processor. The ring The installation frame is fixedly installed on the processing spindle, and the bottom of the ring-shaped installation frame is provided with several telescopic rods at intervals along the circumferential direction, and multiple thermal radiation receivers are used to measure the number of drill bits or workpieces at different angles and different distances at the same time. The temperature value of each point, and then by processing the temperature value of multiple points, the temperature inside the drilling area can be obtained, so as to accurately complete the measurement of the three-dimensional temperature field inside the drilling area.

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 ...
