Title:
MAGNETORHEOLOGICAL FINISHING MACHINING SYSTEM BASED ON MECHANICAL ARM
Document Type and Number:
WIPO Patent Application WO/2021/164298
Kind Code:
A1
Abstract:
A magnetorheological finishing machining system based on a mechanical arm, comprising a mechanical arm having multiple joints connected in series and a magnetorheological liquid circulation system distributed on the mechanical arm. The magnetorheological liquid circulation system comprises: a recovery pump (9) provided on a first joint (14), a liquid storage tank (5) and a supply pump (6) provided on a second joint (3), a magnetic field generation device (17) provided on a tail-end joint (15), a finishing wheel (13), a nozzle (12), a damper (10), and a recovery device (19), and further comprises a first supply pipe (4) connecting the liquid storage tank (5) and the supply pump (6), a second supply pipe (7) connecting the supply pump (6) and the damper (10), a third supply pipe (11) connecting the damper (10) and the nozzle (12), a first recovery pipe (16) connecting the recovery device (19) and the recovery pump (9), and a second recovery pipe (8) connecting the recovery pump (9) and the liquid storage tank (5). The magnetorheological liquid circulation system is split into sub-components, and the sub-components of the magnetorheological liquid circulation system are arranged on the mechanical arm in a distributed layout manner by combining the characteristics of the mechanical arm and the magnetorheological liquid circulation system; under the driving of the mechanical arm, the magnetorheological liquid circulation system implements six-degree-of-freedom movement, and has characteristics such as good movement performance, large speed and acceleration, flexible movement, and small floor area.
