Title
(EN) A MECHANISM FOR SEPARATING ROTARY AND LINEAR MOVEMENT OF A GUIDE SHAFT AND A DEVICE FOR MEASURING THE POSITION OF THE GUIDE SHAFT, COMPRISING SAID MECHANISM
(FR) MÉCANISME POUR SÉPARER UN MOUVEMENT ROTATIF ET LINÉAIRE D'UN ARBRE DE GUIDAGE ET DISPOSITIF POUR MESURER LA POSITION DE L'ARBRE DE GUIDAGE, COMPRENANT LEDIT MÉCANISME
Abstract
(EN) The body for separating the rotational and linear motion solves the problem of separating the rotational and linear motion of the guide shaft (3). According to the invention, the body includes a guide shaft (3), a static part (2) of the body and a rotary part (1) of the body. The movement of the guide shaft (3) relating to the static part (2) is enabled by the first supports (7). The transmission of the rotation of the guide shaft (3) is ensured with the rotation transmission attachment (12), which is attached to the guide shaft (3). With the help of second supports (13) inside the rotation transmission attachment (12) for transmitting rotation, and one or more guides (11), the rotation transmission attachment (12) transfers rotation to the rotary part (1) of the body, which is, via a connecting element (10) with one or more third supports (14), separated from the static part (2) of the body. The rotation of the guide shaft (3) is transmitted via the rotation transmission attachment (12) to the rotary part (1) of the body, using the guides (11) and the connecting element (10) to which the guides (11) are fixed. The device for simultaneously measuring rotary and linear movement of the guide shaft (3) includes said body and position encoders, which are mounted on the body. The body further includes an encoder readhead (9) for measuring rotation and an encoder readhead (8) for measuring linear movement, both mounted in the static part (2) of the body, an encoder scale (B) mounted in the rotary part (1) of the body for measuring rotation, and an encoder scale (D) integrated in the guide shaft (3) for measuring the linear movement.
(FR) Le corps pour séparer le mouvement rotatif et linéaire résout le problème de séparation du mouvement rotatif et linéaire de l'arbre de guidage (3). Selon l'invention, le corps comprend un arbre de guidage (3), une partie statique (2) du corps et une partie rotative (1) du corps. Le mouvement de l'arbre de guidage (3) relatif à la partie statique (2) est permis par les premiers supports (7). La transmission de la rotation de l'arbre de guidage (3) est assurée avec la fixation de transmission de rotation (12), qui est fixée à l'arbre de guidage (3). À l'aide de deuxièmes supports (13) à l'intérieur de la fixation de transmission de rotation (12) pour transmettre la rotation, et un ou plusieurs guides (11), la fixation de transmission de rotation (12) transfère la rotation à la partie rotative (1) du corps, qui est, par l'intermédiaire d'un élément de liaison (10) avec un ou plusieurs troisièmes supports (14), séparée de la partie statique (2) du corps. La rotation de l'arbre de guidage (3) est transmise par l'intermédiaire de la fixation de transmission de rotation (12) à la partie rotative (1) du corps, à l'aide des guides (11) et de l'élément de liaison (10) auquel les guides (11) sont fixés. Le dispositif de mesure simultanée du mouvement rotatif et linéaire de l'arbre de guidage (3) comprend ledit corps et des codeurs de position, qui sont montés sur le corps. Le corps comprend en outre une tête de lecture de codeur (9) pour mesurer la rotation et une tête de lecture de codeur (8) pour mesurer un mouvement linéaire, toutes deux montées dans la partie statique (2) du corps, une échelle de codeur (B) montée dans la partie rotative (1) du corps pour mesurer la rotation, et une échelle de codeur (D) intégrée dans l'arbre de guidage (3) pour mesurer le mouvement linéaire.
