Abstract

CE MANDRIN EST DU TYPE COMPRENANT UN CORPS CONSTITUE PAR DEUX PARTIES CYLINDRIQUES COAXIALES ET DE SECTIONS DIFFERENTES DONT LA PARTIE DE PLUS GRANDE SECTION COMPORTE DES MOYENS DE FIXATION SUR UNE MACHINE, ET A L'EXTREMITE DE PLUS PETITE SECTION DUQUEL DEBOUCHENT DES ALESAGES CYLINDRIQUES INCLINES PAR RAPPORT A L'AXE DU CORPS ET CONVERGEANT DU COTE DE PLUS PETITE SECTION, CHAQUE ALESAGE SERVANT AU LOGEMENT ET AU GUIDAGE D'UN MORS DE SERRAGE DE L'OUTIL, LA PARTIE DE PLUS GRANDE SECTION DU CORPS ETANT ENTOUREE D'UNE CHEMISE SUSCEPTIBLE DE PIVOTER AUTOUR DU CORPS, SUR LA FACE INTERNE DE LAQUELLE EST BLOQUE EN ROTATION UN ECROU QUI, LOGE DANS UN EVIDEMENT PERIPHERIQUE DU CORPS, COOPERE AVEC DES PARTIES FILETEES QUE COMPORTE CHAQUE MORS. SELON L'INVENTION, LE TARAUDAGE DE L'ECROU ET LES PARTIES FILETEES QUE COMPORTE CHAQUE MORS SONT DANS UN SENS TEL QUE LE SERRAGE DES MORS SE PRODUISE POUR UN SENS DE ROTATION DE L'ECROU CORRESPONDANT AU SENS DE ROTATION DE L'ARBRE MOTEUR. APPLICATION AUX PERCEUSES A PERCUSSION.THIS CHUCK IS OF THE TYPE INCLUDING A BODY CONSTITUTED BY TWO COAXIAL CYLINDRICAL PARTS AND DIFFERENT SECTIONS OF WHICH THE PART WITH A LARGER SECTION CONTAINS MEANS OF FIXING ON A MACHINE, AND AT THE END OF A SMALLER SECTION OF WHICH THE CYLINDRICAL BORES EXIT THROUGH THE LARGER SECTION. RELATION TO THE AXIS OF THE BODY AND CONVERGING FROM THE SIZE OF THE SMALLEST SECTION, EACH BORE SERVING FOR THE HOUSING AND GUIDING OF A TOOL TIGHTENING JAW, THE LARGER SECTION OF THE BODY BEING SURROUNDED BY A SUSCEPTIBLE SHIRT TO PIVOT AROUND THE BODY, ON THE INTERNAL FACE OF WHICH IS BLOCKED IN ROTATION A NUT WHICH, LOCATED IN A PERIPHERAL RECESS OF THE BODY, COOPERATES WITH THE THREADED PARTS CONTAINED BY EACH JAW. ACCORDING TO THE INVENTION, THE THREADING OF THE NUT AND THE THREADED PARTS IN EACH JAW ARE IN A DIRECTION SUCH THAT THE TIGHTENING OF THE JAWS OCCURS FOR A DIRECTION OF ROTATION OF THE NUT CORRESPONDING TO THE DIRECTION OF ROTATION OF THE MOTOR SHAFT .
