Abstract

Aiming at the technical problems of high-efficiency, high-quality finishing and flexible control of complex curved surfaces, a magnetic field-assisted finishing device and method for complex curved surfaces based on a parallel mechanism were invented. The device includes a three-bar parallel mechanism, a connecting plate, a column, a workpiece clamping device, a magnetic field generating device, a rotating platform, a three-axis precision displacement platform and a base. The magnetic field generating device includes a baffle plate, a magnetic pole, a T-bolt, a round groove disc and a T-nut. One end of the rotating platform is fixed on the three-axis precision displacement platform, and the other end is fixedly connected to the magnetic field generator. The parts to be processed are fixedly connected to the end rotating platform of the three-bar parallel mechanism through the workpiece clamping device. The multi-degree-of-freedom flexible adjustment is realized through the three-bar parallel mechanism, and the automatic finishing processing of parts with different surface shapes can be completed with the motion control of the rotary platform and the three-axis precision displacement platform. The invention can break through the limitation of the traditional method on complex curved surface finishing, so as to realize efficient flexible automatic finishing.

Description

technical field [0001] The invention relates to the magnetic field-assisted finishing processing technology of complex curved surfaces, and in particular provides a magnetic-field-assisted finishing processing device based on a parallel mechanism and a finishing processing method thereof. Background technique [0002] Finishing is the ultimate link of machining, the main purpose is to improve the surface quality of parts. Finishing mainly includes manual grinding and polishing with fixed abrasives or free abrasives, mechanical traditional finishing, non-traditional finishing and composite non-traditional finishing. Manual grinding and polishing can realize smoothing of planes, rotary bodies, and free-form surfaces. However, this method is labor-intensive, and is affected by the technical level and technical proficiency of workers, resulting in unstable quality and low efficiency. In order to further improve the polishing method and obtain higher processing precision and sur...
