| 摘要 |
The invention relates to a machining device comprising a machining head (10) capable of displacement along at least three translation axes X, Y, Z for machining an immobile part fixed above the machining head (10), said machining head being maintained in a constant orientation by at least three articulated connecting rods (31a, 32a, 31b, 32b). Two connecting rods (31a, 32a) define together with the machining head and with a first Y carriage (33a), on which they are articulated, an deformable articulated parallelogram in the XZ plane. Another connecting rod (31b) is articulated on the machining head (10) and on a second Y carriage (33b). The first Y carriage (33a) is capable of displacement along Y on a first X carriage (20a) capable of displacement along X, and the second Y carriage (33b) is capable of displacement along Y on a second X carriage (20b) capable of displacement along X. The relative movement along X of the X carriages results in a displacement in the Z direction. Several devices can be positioned in a plurality of tunnels (40), said tunnels being arranged so as to share several means (107, 108, 109). |
