Abstract

The invention provides a curved-surface thin-wall part vibration control device based on permanent magnet driving. The device comprises an electromagnetic permanent magnet driving mechanism, a drivenmechanism, a movement conversing mechanism and a self-adaptive jacking mechanism; the electromagnetic permanent magnet driving mechanism is arranged on the base, and the electromagnetic permanent magnet driving mechanism is connected with the driven mechanism and provides a power source for the driven mechanism; the driven mechanism is connected with the movement conversing mechanism, the movementconversing mechanism converts the reciprocating movement of the driven mechanism into vertical movement; and the movement conversing mechanism is also arranged on the base, the movement conversing mechanism is connected with the self-adaptive jacking mechanism, and the self-adaptive jacking mechanism can move up and down under driving of the movement conversing mechanism. According to the curved-surface thin-wall part vibration control device, the movement output of a plurality of positions can be realized by one driving source, so that the driving sources are saved, and the overall structureof a system is more compact, and in addition, the power source is generated by utilizing an electromagnetic permanent magnet mode, so that compared with a linear motor and a voice coil motor with thesame size, the output rigidity of the electromagnetic permanent magnet driving mechanism is larger.

Description

technical field [0001] The present invention relates, in particular, to a vibration control device for curved thin-walled parts based on permanent magnet drive. Background technique [0002] During the processing of large thin-walled surface parts (such as skins of aircraft and rockets), due to the large size of the workpiece and the small stiffness in the thickness direction, the vibration generated by the tool is easy to excite the vibration of the thin-walled workpiece. In order to suppress the vibration, the present invention proposes an active vibration damping device based on permanent magnet drive. [0003] The invention patent with the publication number CN109590776A discloses a flexible clamp based on magnetorheological fluid, including a mounting base, a telescopic body fixedly connected to the mounting base, and a clamping body installed on the side of the telescopic ladder away from the mounting base; the clamping body It includes a base, two movable clamps, a m...
