(DE) EINWELLIGE ELEKTRISCHE SCHRAUBENANZUGSMASCHINE MIT GIERBEWEGUNG
(EN) SINGLE-SHAFT YAW ELECTRIC BOLT-TIGHTENING MACHINE
(FR) MACHINE DE SERRAGE DE BOULONS ÉLECTRIQUE À MOUVEMENT DE LACET À ARBRE UNIQUE
Abstract
(EN)
A single-shaft yaw electric bolt-tightening machine, comprising a base (1), a bracket (2), an electric tightening shaft assembly (14), a sleeve (15), a reaction force supporting board (16), a dedicated sleeve (17), a reaction force sleeve (18), a servomotor (19), a torque sensor (20), an angle sensor (21) and a connecting shaft (22). The bracket (2) is fixed on the base (1) and is provided with a rotary servomotor (3) and an encoder (4). The rotary servomotor (3) is connected with an output shaft (5) which is provided with a small pulley (6). The small pulley (6) is fitted with a big pulley (8) by a toothed belt (7). The big pulley (8) is connected with a rotating shaft (9). A guide rod (12) is connected with a rotating arm (10) by a shaft sleeve (11) and is fixed on a cover-plate bracket (13) in which the electric tightening shaft assembly (14) is fixed.

(FR)
L'invention porte sur une machine de serrage de boulons électrique à mouvement de lacet à arbre unique qui comprend une base (1), un support (2), un ensemble arbre de serrage électrique (14), une douille (15), un panneau support de force de réaction (16), une douille spéciale (17), une douille de force de réaction (18), un servomoteur (19), un capteur de couple (20), un capteur d'angle (21) et un arbre de liaison (22). Le support (2) est fixé à la base (1) et il est équipé d'un servomoteur rotatif (3) et d'un encodeur (4). Le servomoteur rotatif (3) est relié à un arbre de sortie (5) équipé d'une petite poulie de courroie (6). La petite poulie de courroie (6) est accouplée à une grande poulie de courroie (8) par une courroie du type cranté (7). La grande poulie de courroie (8) est reliée à un arbre rotatif (9). Une colonne de guidage (12) est reliée à un bras rotatif (10) par une douille d'arbre (11) et elle est fixée sur un support de plaque de recouvrement (13). L'ensemble arbre de serrage électrique (14) est fixé dans le support de plaque de recouvrement (13).
