Active vibration control device and system for electric spindle applicable to high-speed milling processing

Abstract

The invention relates to workpiece processing equipment, and in particular relates to an active vibration control device and system for an electric spindle applicable to high-speed milling processing. A milling device comprises a worktable, a clamp which is arranged on the worktable, a milling cutter of which the position is corresponding to that of the clamp, and spindle which is connected with the milling cutter, wherein the displacement and acceleration parameters of the worktable of a milling machine and the electric spindle of a machine tool are detected through a detector and emitted through a wireless emitter; the information can be received by a computer system in a wireless manner; the computer system is used for computing to obtain the dynamic property parameters of the machine tool, the rotating speed being best for a motor and a vibration node of the electric spindle and sending the information; the rotating speed of the motor can be adjusted to the suitable rotating speed; a hydraulic actuator is controlled by a hydraulic system to displace to the vibration node of the electric spindle, and a force is applied. Therefore, the cutter vibration can be controlled through the vibration control of the electric spindle, and as a result, the vibration of the milling device can be controlled; the high-speed cutting stability can be improved through the active vibration reducing structure, and thus the processing accuracy and safety can be improved.

Description

technical field [0001] The present invention relates to workpiece processing equipment, in particular to an electric spindle active vibration control device and system suitable for high-speed milling Background technique [0002] At present, in high-speed cutting, the stability of high-speed cutting processing system is very important to machining accuracy, workpiece surface quality and safety. Abnormal vibration and self-excited chatter in high-speed cutting will greatly reduce the service life of tools and machine tools. Deteriorating processing conditions, reducing the surface quality of the workpiece, and the cracking of the blade caused by chatter are like bullets out of the chamber, seriously affecting the safety of high-speed cutting. The active damping structure can improve the stability of high-speed cutting, which is conducive to improving machining accuracy and safety.
