摘要:
An articulated structure for a multi-axis robot includes a base having an arm hinged to the base about a first axis and a forearm hinged to the arm about a second axis parallel to the first axis, and wherein the forearm forms a deformable parallelogram structure which includes two connecting rods that are hinged to two plates about respective axes that are perpendicular to the first and second axes. The structure also includes a first electric actuator controlling pivoting of the arm about the first axis, a second electric actuator controlling pivoting of the forearm about the second axis, and a third electric actuator mounted directly on one of the base and the arm for controlling pivoting of one of the connecting rods relative to the plates about the axes that are perpendicular to the first and second axes.
摘要:
A robot structure that has a base, at least a first arm that moves with respect to the base both in translation and in rotation, a movement mechanism for moving the first arm with respect to the base, a member for accepting a tool, and a power supply assembly. The movement mechanism includes a hollow member which moves in translation with respect to one of either the base or the first arm, while being incapable of translational movement independently of the other of the base or the first arm, and the hollow member being movable in rotation with respect to one of either the base or the first arm, while at the same time being incapable of rotational movement independently of the other of the base or the first arm.
摘要:
The articulated structure for a multi-axis robot comprises a stationary base; an arm hinged to the base about a first axis; a forearm hinged to the arm about a second axis parallel to the first axis, the forearm forming a deformable parallelogram structure and comprising two connecting rods that are hinged to two plates about respective axes that are perpendicular to the first and second axes. This structure also comprises a first electric actuator controlling pivoting of the arm about the first axis; a second electric actuator controlling pivoting of the forearm about the second axis; and a third electric actuator controlling pivoting of one of the connecting rods relative to the plates about the axes that are perpendicular to the first and second axes. The third actuator is mounted on the base or on the arm.

This robot structure comprises a base structure (2), at least a first arm (40) that can move with respect to this base structure, both in terms of translation and in terms of rotation, movement means (12, 22, 32) for moving this first arm with respect to the base structure, an accepting member (70) for accepting a tool (72), and a power supply assembly (80).The movement means comprise a hollow movement member (32) which is able to move in terms of translation with respect to one of either the base structure or the first arm, and is incapable of translational movement independently of the other of either the base structure or the first arm, this hollow movement member being able to move in terms of rotation with respect to one of either the base structure or the first arm, while at the same time being incapable of rotational movement independently of the other of either the base structure or the first arm, whereas the power supply assembly (80) extends, from the base structure towards the first arm, through the hollow movement member (32).
摘要:
A process for assembling and an epicyclic reduction gear comprising a plurality of planets provided with outer toothings moveable rotatable about a shaft which are engaged with the toothings of, at least one adjacent gear ring. The shaft of the planets is mounted on a planet-holder so that it is adapted to move with respect to said planet-holder both radially and angularly in a plane perpendicular to the principal shaft of the reduction gear. The rotation shaft of each planet may be radially and angularly adjusted to a position where its outer toothing meshes with the toothing of the adjacent gear ring and may thereafter be secured in position.

The robot comprises: a controller (C), including power modules (22) for supplying the motors (10) of the arm (A) of the robot (R), a CPU unit (26), for calculation and processing and connection means (52, B), between the arm (A), the power modules (22) and the CPU unit (26). The connection means (52, B) comprise a single functional bus (B) which connects a control unit (30), associated with the CPU unit (26), firstly to the power modules (22) and, also, to the digital interfaces (14) with the sensors (12) of the arms (A). Said interfaces (14) are either integrated with the arm (A) or located in the immediate vicinity thereof.

摘要:
A speed reducer of the cycloidal type for robots and other industrial manipulators including a rotating ring which receives input at rapid speed is supported within a casing by a single end bearing which forms a pivot. The opposite end of the ring abuts against roller bearings associated with a pair of cams. Actuation fingers are oriented through housings created by openings in the cams and are connected to an output. The actuation fingers are arranged to be self-centered in the housings.
