Machine tool spindle temperature measurement device and measurement method thereof

Abstract

The invention discloses a machine tool spindle temperature measurement device and a measurement method thereof. The device comprises a temperature measurement device, a mounting device and a receiving device, wherein the temperature measurement device includes a temperature acquisition module, a signal processing module, a wireless communication module, a storage module and a power supply module;the receiving device includes a signal processing module, a wireless communication module and a serial communication module; and the mounting device includes a measuring rod and a locking module. Thetemperature acquisition module is used for acquiring temperature signals and transmitting the temperature signals to the signal processing module; the signal processing module is used for processing the data signals and then transmitting the processed signals to the receiving device through the wireless communication module in a wireless manner; and the receiving device is used for directly displaying the monitoring data or transmitting the received monitoring data to a computer for display and storage through a serial port. The temperature measurement device is fixed on the mounting device, and the mounting module can be fixed and fastened on the measured spindle through the simple operation, and can be detached conveniently and mounted on spindles with different specifications, thereby achieving tool-free operation.

Description

technical field [0001] The invention mainly relates to the field of temperature monitoring of machine tool spindles, in particular to an on-line machine tool spindle temperature measuring method and device. Background technique [0002] The development of modern machinery industry has put forward higher and higher requirements for the machining accuracy of machine tools. The main factor affecting the machining accuracy of high-speed machine tools is thermal error, which accounts for about 40% to 70% of the total error of the machine tool. The thermal deformation error of the main shaft part is an important factor causing the thermal deformation error of the machine tool. The deformation of the spindle will seriously reduce the machining accuracy of the machine tool and cause a high defective rate, so the measurement of the spindle temperature is very important. [0003] Some spindle temperature measurement methods widely used at present are difficult to directly measure th...

AI Technical Summary

Problems solved by technology

The deformation of the spindle will seriously reduce the machining accuracy of the machine tool, resulting in a high defective rate, so the measurement of the spindle temperature is very important

[0003] Some spindle temperature measurement methods widely used at present are difficult to directly measure the spindle core temperature of the machine tool spindle in the running state

Some use infrared non-contact measurement, it is difficult to measure the temperature distribution along the axis of the main shaft
