Title
(DE) MEISSELANORDNUNG FÜR EINEN RUNDSCHAFTMEISSEL
(EN) CHISEL ARRANGEMENT FOR A ROUND SHANK CHISEL
(FR) SYSTEME DE BURINAGE POUR TREPAN A QUEUE CYLINDRIQUE
Abstract
(DE)
Die Meißelanordnung für einen Rundschaftmeißel (4) sieht eine Meißelbüchse (3) mit einem einen konischen Teilbereich (8) aufweisenden Außenmantel vor. Die Meißelbüchse (3) weist weiters einen die Aufnahmebohrung (2) des Meißelhalters (1) übergreifenden Anschlag (6) auf. Weiters ist die Meißelbüchse (3) über ein Gewinde (9) mit einem großen axialen Spiel in die Aufnahmebohrung (2) des Meißelhalters (1) einschraubbar. Schließlich ist zur Abstützung radialer Kräfte ein zylindrischer Endabschnitt (10) an der Meißelbüchse (3) vorgesehen.
(EN)
The invention relates to a chisel arrangement for a round shank chisel (4), which arrangement provides for a chisel bushing (3) with an outer casing having a conical zone (8). The chisel bushing (3) also has a stop (6) engaging over the location bore (2) of the chisel holder (1). The chisel bushing (3) can also be screwed into the location bore (2) of the chisel holder (1) by way of a thread (9) with a large degree of axial play. A cylindrical end section (10) is provided on the chisel bushing (3) to counteract radial forces.
(FR)
L'invention concerne un système de burinage pour trépan à queue cylindrique (4), où il est prévu un manchon de trépan (3) avec une enveloppe extérieure présentant une zone partielle (8) conique. Le manchon du trépan (3) comporte en outre une butée (6) qui empiète sur la cavité (2) prévue pour recevoir le porte-trépan (1). Le manchon du trépan (3) peut être vissé dans la cavité (2) prévue pour recevoir le porte-trépan (1) par l'intermédiaire d'un filetage, avec un jeu axial important. Pour finir, il est prévu une section terminale (10) cylindrique au niveau du manchon du trépan (3) pour supporter les efforts radiaux.
