Implementation method of intelligent electric spindle control

Abstract

The invention discloses an intelligent electric spindle control implementation method and belongs to the technical field of intelligent equipment. The intelligent electric spindle control implementation method comprises one of or combination of more than two of the following control implementation methods: 1, an intelligent pre-tightening force adjusting device is arranged through matching with an electric spindle to adjust a pre-tightening force in real time; 2, temperature sensors are arranged in a front bearing position, an outer sleeve and a driving rotor, and the coolant flow is intelligently adjusted according to temperature signals acquired by the temperature sensors; 3, a dynamic torque detection system is arranged through matching with the electric spindle to monitor a dynamic torque in the working process of the electric spindle in real time; 4, the spindle end runout volume of the electric spindle is detected through a driving end runout detection system of the electric spindle. The intelligent electric spindle control implementation method achieves intelligent operation of the electric spindle by detecting and controlling operation parameters of the intelligent electric spindle, improves the operation precision of the electric spindle, prolongs the service life of the electric spindle and provides reliable theoretical parameters for a part machining process.

Description

technical field [0001] The invention relates to an implementation method of intelligent electric spindle control, and belongs to the technical field of intelligent equipment. Background technique [0002] The design and manufacture of domestic electric spindles mostly refer to the design of foreign electric spindles, which largely restricts the technological innovation and industrial development of electric spindles in my country. Most of the existing domestic electric spindles are driven by built-in asynchronous motors through frequency conversion. The common disadvantages are: First, the existing domestic electric spindles do not have running state parameter detection sensors and control methods, and have no running state parameter signal output and intelligent adjustment functions. ; Second, the operating state parameters of existing electric spindles in China cannot be dynamically detected and analyzed, and a better correspondence between workpieces, processes, and opera...

Most of the existing domestic electric spindles are driven by built-in asynchronous motors through frequency conversion. The common disadvantages are: First, the existing domestic electric spindles do not have running state parameter detection sensors and control methods, and have no running state parameter signal output and intelligent adjustment functions. ; Second, the operating state parameters of existing electric spindles in China cannot be dynamically detected and analyzed, and a better correspondence between workpieces, processes, and operating parameters cannot be established. The method of intelligent control, the bearing pretightening force of the existing electric spindle is constant, and there is no method for dynamically adjusting its running speed, load bearing and spindle rigidity
