Abstract

The invention discloses a combined intelligent self-powered vibration-damping boring bar, which comprises a boring bar, a first piezoelectric ceramic sheet, a second piezoelectric ceramic sheet, an electrorheological fluid, a large mass block, a positioning gear ring, a small mass block, The third piezoelectric ceramic sheet, the sealing gear ring, the controller, the end cover, a small mass block is arranged inside the third piezoelectric ceramic sheet, and the electrorheological fluid is arranged on the first piezoelectric ceramic sheet and the second piezoelectric ceramic sheet Between, the large mass block is set inside the second piezoelectric ceramic sheet, the controller is fixed on the tail of the boring bar by the end cover, and the inner and outer surfaces of the third piezoelectric ceramic sheet are connected with the controller to form a detection circuit , the outer surface of the first piezoelectric ceramic sheet and the inner surface of the second piezoelectric ceramic sheet are connected with the controller to form a self-powered control loop, the controller calculates the vibration state of the boring bar according to the detection loop, and applies the electrorheological The electric field on the liquid is controlled to change the damping and stiffness of the electrorheological fluid, so that the shock absorber works in the best vibration reduction state.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a combined intelligent self-powered vibration-damping boring bar, which belongs to the technical field of metal cutting. Background technique [0002] In machining, hole machining is usually performed by boring tools. In deep hole machining, the boring bar needs to have a large length-to-diameter ratio. At this time, the boring bar has low rigidity, and cutting chatter is prone to occur, so that the roughness of the machined surface cannot meet the requirements. In order to reduce and suppress the vibration of the boring bar, it is often used Vibration-damped boring bars with vibration absorbers for machining. [0003] Existing vibration-damping boring bars mainly include passive and active types. Among them, passive vibration absorbers cannot automatically adjust stiffness and damping according to working conditions, and are poorly targeted; active vibration absorbers often require external po...
