Title:
METHOD FOR DETERMINING REAL-TIME THERMAL DEFORMATION ATTITUDE OF SPINDLE
Document Type and Number:
WIPO Patent Application WO/2020/155230
Kind Code:
A1
Abstract:
Disclosed is a method for determining a real-time thermal deformation attitude of a spindle, the method comprising: firstly, respectively applying temperature sensors (1, 3) and displacement sensors (5, 6) to testing the temperatures of upper and lower surfaces of a spindle box (2) and a radial thermal error of a spindle during the operation of the spindle; secondly, calculating, according to the radial thermal error of the spindle, the amounts of thermal variation of the upper and lower surfaces of the spindle box, and establishing a model between the amounts of thermal variation and the temperatures of the upper and lower surfaces of the spindle box; and finally, determining a real-time thermal deformation attitude of the spindle according to the temperatures, collected in real time, of the upper and lower surfaces of the spindle box. The method can achieve real-time monitoring of the thermal deformation attitude of the spindle during a machining process.
