Problems solved by technology

Since the cutting area of ​​the drilling process is semi-closed, the radiation cannot directly reach it, so this method is not suitable for the cutting temperature measurement of the drilling process
[0004] At present, the measurement of drilling temperature is still mainly based on the collection of instantaneous cutting temperature, and it is still impossible to continuously monitor the change of drilling temperature

Embodiment Construction

[0016] The invention is a device for continuously changing cutting temperature monitoring in a drilling system. It is based on the principle of artificial thermocouple temperature measurement. By setting the experimental device on the spindle box of a machine tool at one time, it can realize the long-term operation of the entire test piece hole processing cycle. Time and continuous cutting temperature monitoring, specifically using the thermocouple fixing frame device and the drilling temperature measurement fixture, so that the thermocouple moves synchronously with the drill bit along the axial direction at all times, and realizes long-term and continuous cutting temperature collection.

[0017] Below in conjunction with embodiment and accompanying drawing, the present invention is described in detail, present embodiment is based on the premise of technical solution of the invention, has provided detailed implementation method and specific operation process, but protection scop...

Abstract

The invention discloses a cutting temperature monitoring device for drilling and cutting. The device comprises a thermocouple fixing bracket assembly, and a drilling and cutting temperature measuring clamp, wherein the thermocouple fixing bracket assembly is absorbed onto a main shaft box; the drilling and cutting temperature measuring clamp is mounted on a workbench and provides sufficient space for a thermocouple to axially move. According to the method, the experimental arrangement of one-time clamping testing part is performed to achieve continuous monitoring of the cutting temperature in the whole drilling process of the testing part.

Description

technical field [0001] The invention relates to a novel method for measuring the drilling temperature in the drilling temperature measurement test. 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, drilling technology has been widely valued. However, as a semi-closed machining method, drilling itself has relatively harsh cutting conditions, and the drilling heat is concentrated in the cutting area where the drilling tool interacts with the workpiece, which can easily cause severe deformation of the material. Drilling...
