Title:
PARALLEL LINK MECHANISM AND LINK OPERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/196164
Kind Code:
A1
Abstract:
This parallel link mechanism is provided with a base-end link hub (1), three link mechanisms (11), a rotating body (2a), and a distal-end link hub (3). The rotating body (2a) is connected to one of the three link mechanisms (11). The rotating body (2a) is rotatably coupled to the base-end link hub (1). In the link mechanism (11), first center axes (15a – 15c) of first rotation joint parts (25a – 25c) and second center axes (16a – 16c) of second rotation joint parts intersect at a spherical link center point (30). The axis of rotation 12 of the rotating body (2a) intersects the spherical link center point (30).
