Driving device for displacing a platform in a plane

摘要

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.
