Workpiece machining device, has rods forming parallelogram with head and Y carriage, and X carriages that are respectively mobile along directions parallel to Y axis on X carriages mobile that are along directions parallel to X axis

摘要

The device has two connecting rods forming a deformable articulated parallelogram with a machining head (10) and a Y carriage (33a) in a plane defined by X and Z directions. A third connecting rod (31b) is articulated on the head and another Y carriage (33b) such that an articulated assembly formed by the rod (31b), the head and the carriage (33b) is deformable in the plane defined by X and Z directions. The carriages (33a, 33b) are respectively mobile along two directions parallel to a Y axis on two X carriages (20a, 20b) that are mobile along directions parallel to an X axis.
