Title:
PARALLEL LINK MECHANISM AND LINK OPERATION DEVICE
Document Type and Number:
Japanese Patent JP2021008926
Kind Code:
A
Abstract:
To provide a parallel link mechanism and a link operation device in which a tip member is movable on a spherical surface having a constant radius from a fixed rotation center, a rotation radius of the tip member can be controlled independently from rotary movement, and a service life can be improved by suppressing vibration.SOLUTION: In a parallel link mechanism 10, three or more link mechanisms 11A-11C are configured to connect a base end member 1 and a tip member 8. In the three or more link mechanisms 11A-11C, first center axes 15a, 15b, 15c of first revolute pair portions R1 and second center axes 16a, 16b, 16c of second revolute pair portions R2 are intersected with each other on a spherical surface link center point 30. Fifth center axes of fifth revolute pair portions R5 in each of the three or more link mechanisms 11A-11C are overlapped, and intersected with the spherical surface link center point 30. The fifth revolute pair portions R5 of the three or more link mechanisms 11A-11C are independently disposed on positions different from each other.SELECTED DRAWING: Figure 1
