Title

Hexapod-Lagerungseinrichtung

Other Title
Hexapod bearing device for machine tools - has one of support attachment points on one side of frame bearing with remaining support attachment points mounted on opposite second side, relative to axis of support passing through frame bearing.
Abstract
The bearing device has a support (3) movable relative to a frame bearing (2) and connected to same by six length-adjustable stays (4) each attached to the frame bearing and support at attachment points. At least one of the support attachment points (T1) is mounted on a first side of the frame bearing in relation to an axis (A) of the support passing through the frame bearing, whilst the remaining support attachment points are mounted on the opposite second side of the frame bearing. Three stays can be mounted on the first side and three on the second side. The frame attachment points (G1) can be mounted in a common plane. The frame bearing can be a ring-shaped frame part enclosing a work chamber (6) containing the support. ADVANTAGE - Improves rigidity of bearing through spaced positioning of attachment points whilst not impeding mobility of support
