Abstract

See full text

A five-degree-of-freedom parallel mechanism and a series-parallel multi-degree-of-freedom equipment having the parallel mechanism are disclosed, and can machine complex components and parts as well as large structural parts and implement multi-degree-of-freedom numerical control machining, such as offsite maintenance of large equipment. The parallel mechanism includes: a rack; a movable platform; a first chain connected with the rack by at least two revolute pairs with axes intersecting with each other perpendicularly, and connected with the movable platform by at least two revolute pairs with axes intersecting with one another perpendicularly; a second chain having the same structure as the first chain; and a third chain including a main branch chain and two auxiliary branch chains, wherein the first chain, the second chain, and the third chain are separately connected between the rack and the movable platform.
