Mechanical-magnetorheological composite flexible fixture for thin-walled parts

Abstract

A kind of mechanical-magnetorheological composite flexible fixture of thin-walled parts, comprising: a plurality of mechanical clamping modules for rigidly clamping workpiece and ensuring the positioning of workpiece;A plurality of magnetorheological flexible clamping modules for providing damping support to workpiece, each comprising an adaptive head, a magnetorheological fluid damping part and a jacking part connected in turn from top to bottom, respectively for adaptive contact and support the bottom surface of workpiece, provide damping support force, and drive the adaptive head and magnetorheological fluid damping part to rise and fall;Control unit. Wherein, the magnetorheological flexible clamping module makes the fixture realize flexible clamping, and the plurality of magnetorheological flexible clamping modules can ensure that workpiece is supported enough, the adaptive head minimizes the influence of clamping on the surface of workpiece. The control unit can control the magnetorheological flexible clamping module to actively loosen the support of workpiece, release the machining deformation of workpiece, so that the machining deformation of the workpiece is well controlled, thereby improving the machining quality of workpiece.
