Cutting temperature monitoring device for high-speed drilling process

Abstract

The invention discloses a cutting temperature monitoring device for high-speed drilling process. The cutting temperature monitoring device comprises a temperature module housing assembly and a temperature monitoring system. The temperature module housing assembly is arranged on a handle of a cutting tool, and the temperature monitoring system is arranged in the temperature module housing assembly. The temperature monitoring device is capable of continuously monitoring the cutting temperature in the life cycle of the cutting tool for a long time through a one-time experimental setting of the cutting tool. The temperature monitoring device is sound in balancing performance without requiring for the material of workpieces, and is applicable to measuring and recording of the long-time and continuously variable cutting temperature of metal and nonmetallic materials in the high-speed drilling process.

Description

Technical field [0001] The invention relates to a cutting temperature monitoring device, in particular to a cutting temperature monitoring device used for high-speed drilling processing, and belongs to the technical field of mechanical engineering. Background technique [0002] Drilling is the most basic cutting method in the traditional machining process. It is used to create holes on the workpiece. The drilling process accounts for about 40-50% of the total machining. In recent years, with the trend of material-structure integration of mechanical structural parts, the proportion of assembly and connection hole making technology has increased rapidly. In order to ensure the quality of holes and improve processing efficiency, high-speed drilling technology has been widely valued. However, drilling itself as a semi-closed machining method, the cutting conditions are relatively harsh, the drilling force and drilling heat are relatively concentrated in the cutting area where the dri...

Problems solved by technology

However, both methods involve making a small hole with a diameter of less than 0.5mm on the workpiece and embedding the thermocouple, and there are strict requirements on the position where the thermocouple is buried, so the experimental setup is more complicated, and one experimental setup can only be completed The measurement of a cutting instantaneous temperature value, but the monitoring record of the long-term and continuously changing cutting temperature that has a direct impact on tool life and hole processing quality cannot be obtained

In addition, for some workpiece materials (such as resin-based reinforced composite materials) that cannot use electric sparks to make small holes, semi-manual thermocouple temperature measurement is also difficult in practice
