Programmable intelligent electric spindle

Abstract

The invention discloses a programmable intelligent electric spindle. The programmable intelligent electric spindle comprises a front bearing pedestal, a rear bearing pedestal, a spindle body, a motor rotor, a motor stator, a cooling water jacket, an actuation bearing, an annular pressing block, a tool handle, a controller, a cooling liquid input pipeline, a cooling liquid outlet pipeline and a shell of a hollow structure. An annular cavity is formed between the motor stator and the shell, and the cooling water jacket is arranged in the cavity; a plurality of first piezoelectric actuators are evenly arranged between the annular pressing block and the front bearing pedestal in a divided manner in the circumferential direction, and a plurality of grooves are arranged on the inner side of the rear bearing pedestal in the circumferential direction; second piezoelectric actuators are embedded in the grooves; an electromagnetic valve is arranged on the cooling liquid input pipeline; and the output end of the controller is connected with the control end of the electromagnetic valve, and the control ends of the first piezoelectric actuators and the control ends of the second piezoelectric actuators are connected. Vibration and shaft end deformation of the spindle body can be reduced, temperature rising of the spindle body is regulated and controlled, the structure is simple, and the requirements of parts for machining quality diversity can be met.

Description

technical field [0001] The invention relates to an electric spindle, in particular to a programmable intelligent electric spindle. Background technique [0002] Spindle temperature, vibration, rotation accuracy, etc. are the key parameters to measure the performance of the spindle, which have an important impact on the processing quality of the parts. The current intelligent electric spindles mostly use real-time monitoring of these parameters, and optimize these parameters through active regulation, so as to realize online real-time control of parts processing quality, but this method has extremely high real-time requirements for the electric spindle performance control system. In addition, at present, most of the performance control of intelligent electric spindle is a single performance regulation. The design and research of compound regulation have not been reported. Contents of the invention [0003] The purpose of the present invention is to overcome the above-ment...
