Abstract
The device for displacing a platform includes two carriages driven, simultaneously or separately, on guiding rails oriented along an axis X. The two carriages carry a platform mounting slides engaged with slideways on the carriages. At least one of the slides of the platform carriage and at least one of the slideways of the carriage is oriented at an angle other than 90° relative to an axis X. The displacement along any direction of a plane comprised of the axes X and Z of a tool holder spindle or work piece spindle mounted on the platform can be obtained only by the relative or simultaneous moving of the two carriages on the guiding rails.
Claims22
Device for displacing a platform (4) in any direction of a plane comprised of two orthogonal axes (X, Z), comprising:
- a first carriage (2;
- 3′, 6′) which can be driven along the first (X) of the two orthogonal axes,
- a second carriage (3;
- 6) which can be driven along the same first of the two orthogonal axes,
- said two carriages being disposed in a same plane and being guided by the same means (11),
- the platform including a first sliding means (21/40;
- 31′/41′;
- 60′, 61′/43′) relative to the first carriage and a second sliding means (31/41;
- 60, 61/43) relative to the second carriage,
- at least one of the sliding means being oriented along a third axis at an angle (α, α′) other than 90° relative to the first of the orthogonal axes, the third axis being in the same plane as the two orthogonal axes.
