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

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
