Abstract

The invention relates to an active vibration reduction boring rod based on an electromagnetic damper, and belongs to the field of machining. The active vibration reduction boring rod based on the electromagnetic damper solves that problem that an existing active vibration reduction boring rod based on a damper is prone to failure, complex in structure and large in manufacturing difficulty. The active vibration reduction boring rod based on the electromagnetic damper comprises a rod body, the electromagnetic damper, a three-axis acceleration sensor and a control system, wherein a tool bit is arranged at the front end of the rod body, and the tool bit is used for clamping a blade; the electromagnetic damper is arranged inside the rod body. When the vibration reduction boring rod is used forboring, the three-axis acceleration sensor is used for measuring acceleration data of the rod body and sending the acceleration data to the control system, and the control system is used for adjustingthe damping coefficient of the electromagnetic damper until the acceleration data that the control system receives reaches the minimum. The active vibration reduction boring rod based on the electromagnetic damper is suitable for fine boring.

Description

technical field [0001] The invention relates to an active damping boring bar, which belongs to the field of mechanical processing. Background technique [0002] The working principle of the existing damper-based active damping boring bar is: when the boring bar is working, the vibration sensor detects the vibration signal of the boring bar in real time and sends the vibration signal to the controller, and the controller receives the vibration signal Finally, adjust the damping coefficient of the damper to control the amplitude of the boring bar within the normal range. [0003] The dampers used in the existing damper-based active damping boring bars are mainly divided into squeeze oil film dampers, electrorheological fluid dampers and magnetorheological fluid dampers. These active damping boring bars mainly have the following problems : [0004] For the active damping boring bar based on the squeeze film damper: when the actual unbalance of the rotor of the squeeze film da...
