DEVICE FOR THE SPACE TRANSLATION MOVEMENT OF AN ELEMENT INTO SPACE, PARTICULARLY FOR A MECHANICAL ROBOT.

摘要

P The device comprises at least two actuators (12a, 12b, 12c) of the linear cylinder type responsible for varying the linear distance on the cylinder axis between a fixed point relative to the base (1) and a fixed point relative to the mobile working element (2a, 2b, 2c) of the cylinders, the element (2a, 2b, 2c) being able to experience combined movements of translation / rotation along the axis of the fixed cylinder relative to the base (1), the mobile working parts (2a, 2b, 2c) being rigidly fixed (without articulation) on bars 6a, 6b, 6c) of the junction elements (3a, 3b, 3c) of the hinged planes parallelograms type, the mobile platform (8) being mounted in articulation of rotation (78a, 78b, 78c) on a bar (7a, 7b, 7c) which remains parallel to that 6a, 6b, 6c) rigidly fixed to the mobile working part ( 2a, 2b, 2c), the assembly being constructed respecting the parallelism of the axis of the jacks (12a, 12b, 12c) and of the axis of rotation between the bar ( 7a, 7b, 7c) and the platform (8). /P
