Abstract

La présente invention concerne un broyeur de tige d'électrode. Plus spécifiquement, la présente invention concerne un broyeur de tige d'électrode ayant une pince multiple, le broyeur de tige d'électrode comprenant : une pince comprenant un élément de guidage, dont un côté est ouvert de telle sorte qu'une extrémité d'une tige d'électrode soit insérée à l'intérieur de celui-ci, et un élément de maintien contenu dans l'élément de guidage, l'élément de maintien comprenant au moins trois blocs de maintien et un ressort de maintien pour relier des blocs de maintien adjacents l'un à l'autre, les blocs de maintien étant disposés de manière à entourer une extrémité de la tige d'électrode de telle sorte que la tige d'électrode soit serrée et fixée par une force externe ; une unité d'entraînement comprenant un moteur, un cylindre broyeur relié à un arbre d'entraînement du moteur de manière à tourner et un boîtier entourant l'extrémité arrière de l'arbre d'entraînement et du moteur ; et une tête couplée au côté avant du boîtier de manière à contenir le cylindre broyeur, de multiples trous de polissage étant formés sur la surface extérieure de la tête de telle sorte que la pince puisse être montée sur celle-ci. Les trous de polissage sont formés de telle sorte que leur direction d'extension croise la surface avant du cylindre broyeur. Par conséquent, des tiges d'électrode ayant divers diamètres peuvent être insérées dans un trou, et des formes d'extrémité des tiges d'électrode peuvent être formées à des angles souhaités.
