Patent ID: 7886629

Claim:
A manipulator device for moving a tool in a plane of movement along at least two Cartesian axes X and Y, which device is adapted to be used independently or to be installed on a traveling structure of a machine tool, said device including a platform provided with a support for the tool and adapted to travel according to the said axes, a frame, actuators for controlling the movements of the platform, and a support for the platform; the frame being equipped with at least a first and a second main slideway respectively directed according to said axes X and Y, and said device including a first sliding structure and a second sliding structure which are substantially symmetrical to each other and are adapted to travel in the manner of a slide along said first main slideway and along said second main slideway, respectively; each sliding structure being equipped in its turn with a respective auxiliary slideway orthogonal to its traveling direction and the platform being slideably coupled with and supported by the auxiliary slideways of each sliding structure; and each of said actuators including a body fastened to the frame and a driving member mechanically connected to the respective sliding structure; wherein the platform is located in a position between said first sliding structure and said second sliding structure, and it is supported by said auxiliary slideways of the said first and second sliding structures, respectively, on two sides thereof which are orthogonal to each other in order that each sliding structure extends only on a respective side of the platform.
