Intelligent electric spindle

Abstract

The invention discloses an intelligent electric spindle, and belongs to the field of electromechanical technology. The intelligent electric spindle comprises a sleeve. A front bearing pedestal and a rear bearing pedestal are installed at the front end and the rear end of the sleeve respectively. A pressure sensor is arranged on the combination face of the end face of the front bearing pedestal and a front bearing. A pressure servo actuator is fixedly connected with the rear bearing pedestal. A pressure sensor is arranged in front of the pressure servo actuator, and a pressure sensor is arranged behind the pressure servo actuator. An oil inlet and outlet and oil pressure detector valve is connected with a hydraulic station. A vibration sensor and a temperature sensor are arranged inside the front bearing pedestal. A temperature sensor is arranged in the sleeve and a driving rotor. A third temperature sensor is arranged inside the sleeve and the driving rotor. A torsion dynamic detection system is arranged on the electric spindle. According to the intelligent electric spindle, front bearing pretightening force and rear bearing pretightening force of supports inside the intelligent electric spindle are adjusted through the pressure servo actuator, part machining technological parameterization and device intelligentization are achieved, and therefore the production efficiency can be improved, and more stable part machining quality is obtained.

Description

technical field [0001] The invention relates to an electric spindle, in particular to an intelligent electric spindle, which belongs to the field of electromechanical technology. 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 operating state parameter detection sensors, and there is no operating state parameter signal output; The operating state parameters of the spindle cannot be dynamically detected and analyzed; third, the existing domestic electric spindle cannot intelligently control its operating parameters; fourth, the bearing preload of the existing do...
