Abstract

The invention discloses an integrated monitoring ring device of a machine tool spindle, comprising an angular contact bearing of a support principal axis. The angular contact bearing is provided with an inner ring spacer bush and an outer ring spacer bush, wherein the radial direction of the outer ring spacer bush is provided with three eddy current displacement sensors near the inner ring spacer bush along the peripheral direction; the axial direction is provided with one eddy current displacement sensor; the outer edge of the outer ring spacer bush is provided with an acceleration transducer and a temperature sensor; the inner ring spacer bush of the angular contact bearing rotates along with the principal axis in the operation process of the principal axis of the machine tool; four eddy current displacement sensors respectively monitor the axial and radial vibration displacement of the principal axis; the acceleration transducer monitors the vibration acceleration of the angular contact bearing; the temperature sensor monitors the temperature of the angular contact bearing; and finally, comprehensive analysis is carried out to judge the operation state of the principal axis and realize real-time on-lime monitoring of the operation state of the principal axis.

Description

technical field [0001] The invention belongs to the technical field of machine tool spindle monitoring, and in particular relates to a machine tool spindle integrated monitoring ring device for monitoring vibration radial displacement, axial displacement, bearing vibration acceleration, bearing temperature and spindle rotation accuracy. Background technique [0002] Due to high speed, high precision, high efficiency and high flexibility, high-precision machine tools are more and more widely used in the field of mechanical processing, which adds a strong impetus to the modern manufacturing industry and is an important basic equipment of the national economy. High-precision machine tools have a high degree of automation, are expensive, and have complex structures. Once they are stopped due to failure or component failure, huge economic losses will be caused. The spindle system is the most critical part of the machine tool. It directly participates in the cutting process of the...
