Transient milling temperature testing device capable of following cutter-cutting contact abrasion

Abstract

The invention provides a transient milling temperature testing device capable of following cutter-cutting contact abrasion. The transient milling temperature testing device comprises a milling cutter blade, a T-shaped milling cutter handle connected with the milling cutter blade in a matched mode, a temperature collecting and transmitting terminal embedded in the T-shaped milling cutter handle, and a thin film thermocouple temperature sensor capable of following abrasion and embedded in the front cutter face of the milling cutter blade. The thin film thermocouple temperature sensor capable of following abrasion is embedded in the front cutter face of the milling cutter blade, so that a hot contact of the sensor can follow abrasion and the sensor can be detached and replaced, and the problem that the temperature of a contact area between the front cutter face of a cutter and cuttings cannot be measured by a traditional measuring method is solved; and the temperature collecting and transmitting terminal is embedded in the cutter handle, so that a temperature signal can be wirelessly transmitted to a personal computer (PC) end in real time in the milling process to display the real-time temperature in a changing curve form, and a new method and a new technical approach are provided for transient temperature measurement in high-speed milling and precision machining.

Description

technical field [0001] The invention relates to the field of transient milling temperature detection technology and sensor technology, in particular to a milling temperature testing device based on a thin-film thermocouple temperature sensor. Background technique [0002] With the improvement of the automation and intelligence level of the processing system, especially in high-speed, precision and ultra-precision machining, the milling temperature and distribution are one of the key factors affecting tool life and processing quality. Among them, the accurate measurement of temperature and distribution in milling area has always been a hot spot and difficult problem in the research of milling mechanism. Milling temperature is one of the most important parameters in the high-speed milling process. During the cutting process, due to the combined effects of cutting force, cutting heat, cutting-in and cutting-out impact, etc., the contact surface between the tool and the workpiec...

AI Technical Summary

Problems solved by technology

[0003] Since the workpiece is fixed, the tool is rotated, and the blade is cutting intermittently during the milling process, the non-contact temperature measurement method cannot obtain the accurate temperature of the contact area between the rake face of the blade and the chip during processing, and the traditional contact temperature measurement method is easy. Sensor damage due to unavoidable friction
