Flexible polishing head based on magnetorheological elastomer

Abstract

The invention relates to a flexible polishing head based on a magnetorheological elastomer. The flexible polishing head consists of a connecting shaft, a support, a first conducting wire, a second framework, a second electromagnetic coil, a second magnetic isolation sleeve, a supporting cover, the magnetorheological elastomer, abrasive particles, a pressure sensor, a first magnetic isolation sleeve, a first electromagnetic coil, a first framework, a cover plate, a magnet guide core, a sleeve, a second conducting wire and a controller. The connecting shaft is arranged at the top end of the support; the sleeve is arranged at the bottom of the connecting shaft; the second framework is arranged in the outer ring at the bottom end of the support, and the cover plate is arranged at the upper part of the second framework; the first framework is arranged in the inner ring at the bottom of the support, and the magnet guide core is arranged at the upper part of the support; the supporting coveris in threaded connection with the support; the magnetorheological elastomer is arranged between the bottom of the support and the supporting cover; the abrasive particles are embedded in the magnetorheological elastomer; the controller is arranged inside the sleeve, and the first conducting wire and the second conducting wire connected with the output end of the controller are respectively connected to the first electromagnetic coil and the second electromagnetic coil; the first electromagnetic coil and the second electromagnetic coil are respectively arranged in the first framework and the second framework, and the outer sides of the first electromagnetic coil and the second electromagnetic coil are respectively wrapped by the first magnetic isolation sleeve and the second magnetic isolation sleeve; and the pressure sensor is disposed within the magnetorheological elastomer.

Description

Technical field [0001] The invention relates to a polishing tool, in particular to a flexible polishing head based on a magnetorheological elastomer. Background technique [0002] Polishing can be seen everywhere in the machinery industry. The polishing methods generally include manual polishing, mechanical polishing, vibration polishing, drum polishing and electrochemical polishing. Most of the polishing methods use rigid polishing heads. It is difficult to polish complex curved surfaces. The product does not work well. The polishing process of other methods is complicated and requires high technical requirements for the operators, and also produces waste gas and waste water, environmental pollution and other adverse effects. Therefore, the present invention uses the magnetic field to control the stiffness characteristics of the magnetorheological elastomer, and designs a flexible polishing head based on the magnetorheological elastomer. Summary of the invention [0003] The pu...
