Abstract
The device serves for moving a movable platform (2) in respect to a base (1). The connection between platform and base is established by six legs (4a-4f), which are connected to the platform in articulated manner. At the base side, they rest in articulated manner on sliding carriages (6a-6f). The sliding carriages can be displaced along parallel guiding tracks (7a-7c), by means of which position and orientation of the platform can be adjusted. Two sliding carriages are running independently of each other on each guiding track, allowing a movement with a total of six degrees of freedom. Since two sliding carriages share one guiding track, the design is simplified and some drive components can be dispensed with.
Claims19
A moving device for a machine tool or a robot comprising
- a base,
- a mobile part, which is mobile in respect to said base,
- a plurality of substantially parallel tracks that are immobile in respect to said base,
- at least four carriages longitudinally displaceable independently of each other along said tracks, wherein at least two of said carriages are arranged on the same track,
- a plurality of drives, each of said drives being attributed to one of said carriages, and
- at least six legs connecting said base and said mobile part wherein said legs are connected in articulated manner to said mobile part and rest on their base side, in articulated manner on said carriages, wherein each of said carriages is carrying at least one of said legs,
- wherein said carriages are operatable for displacing and tilting said mobile part.
