Abstract

The chisel has retaining units (16,18) divided between two pressing edges (20,21) adjusted transverse to a longitudinal axis of a clamping sleeve and pressed such that the edges extend over a part of a circumference of the sleeve and are at a distance from each other. The distance corresponds to the width of a peripheral groove in a shank. The units form a co-axial concave central section (22) that is turned to a convex groove base.

Description

Die Erfindung betrifft einen Rundschaftmeißel mit Meißelhalter, bei dem der Schaft des Rundschaftmeißels mittels einer geschlitzten Spannhülse in der Bohrung des Meißelhalters gehalten ist, wobei die Spannhülse an der Bohrungswandung der Bohrung verspannt ist und der Schaft des Rundschaftmeißels drehbar in der Spannhülse gehalten ist, wobei die Spannhülse mit nach innen eingestanzten und/oder eingedrückten Halteelementen versehen ist, die über den Umfang der Spannhülse verteilt sind und in eine in den Schaft des Rundschaftmeißels eingebrachte Umfangsnut eingreifen, so dass die Spannhülse in axialer Richtung unverschiebbar auf dem Schaft des Rundschaftmeißels festgehalten ist.The invention relates to a round shank bit with chisel holder, wherein the shank of the round shank chisel is held in the bore of the chisel holder by means of a slotted clamping sleeve, wherein the clamping sleeve is clamped to the bore wall of the bore and the shaft of the round shank chisel is rotatably held in the clamping sleeve, wherein the Clamping sleeve is provided with inwardly stamped and / or depressed holding elements, which are distributed over the circumference of the clamping sleeve and engage in an inserted into the shank of the round shank chisel circumferential groove so that the clamping sleeve is held immovably in the axial direction on the shank of the round shank chisel.

Bei einem derartigen Rundschaftmeißel mit Meißelhalter ist die axiale Stellung der Spannhülse auf dem Schaft des Rundschaftmeißels wichtig, damit die Stirnseiten der Spannhülse freiliegen und die Spannhülse ein möglichst kleines Axialspiel besitzt. Zudem muss der Schaft des Rundschaftmeißels in der Spannhülse durch die Haltetechnik so zentriert sein, dass der Schaft frei drehbar in der, in der Bohrung des Meißelhalters verspannten Spannhülse geführt ist.In such a round shank chisel with chisel holder, the axial position of the clamping sleeve on the shank of the round shank chisel is important so that the front sides of the clamping sleeve exposed and the clamping sleeve has the smallest possible axial play. In addition, the shaft of the round shank chisel in the clamping sleeve must be centered by the holding technique so that the shaft is freely rotatably guided in the, clamped in the bore of the chisel holder clamping sleeve.

Ein Rundschaftmeißel mit Meißelhalter der eingangs erwähnten Art ist aus der EP 0 264 015 A1 , der US 4,850,649 und der DE 37 12 427 A1 bekannt. Bei diesen Rundschaftmeißeln mit Meißelhalter sind die Halteelemente punkt- oder stegartig nach innen eingedrückt, so dass sie in der Umfangsnut des Schaftes ein mehr oder weniger großes Axialspiel aufweisen, das sich bei verspannter Spannhülse in der Bohrung des Meißelhalters auch auf den Rundschaftmeißel auswirkt: Zudem bieten die Halteelemente in der Umfangsnut des Schaftes des Rundschaftmeißels keine ausreichenden Führungsflächen für eine eindeutige Zentrierung des Schaftes, wodurch dessen Drehbewegung in der Spannhülse beeinträchtigt ist.A round shank chisel with chisel holder of the type mentioned is from the EP 0 264 015 A1 , of the US 4,850,649 and the DE 37 12 427 A1 known. In these round shank chisels with chisel holder the holding elements point or web-like are pressed inwards, so that they have a more or less large axial play in the circumferential groove of the shank, which also affects the round shank chisel in the bore of the chisel holder in the clamped clamping sleeve the holding elements in the circumferential groove of the shank of the round shank chisel no sufficient guide surfaces for a clear centering of the shank, whereby its rotational movement is impaired in the clamping sleeve.

Aus der US 4,327,947 ist ein Rundschaftmeißel bekannt, der in einer umlaufend in den Meißelschaft eingebrachten Nut eine Spannhülse komplett aufnimmt. Dabei kommen die längsseitigen Enden der Spannhülse mit den Nutseitenwänden in Eingriff.From the US 4,327,947 is a round shank chisel known, which accommodates a clamping sleeve in a circumferentially introduced into the chisel shaft groove completely. In this case, the longitudinal ends of the clamping sleeve come into engagement with the groove side walls.

Eine weitere Ausgestaltung eines Rundschaftmeißels ist in der EP 0 295 232 gezeigt. Hierbei weist die Spannhülse über ihren gesamten Umfang eine Nut auf, die in Richtung auf den Meißelschaft eingewalzt ist. Mit dem so ausgeformten Hütsenmaterial greift die Spannhülse in die umlaufende Nut im Meißelschaft ein. Die WO 03/004832 A1 zeigt schließlich eine Spannhülse, bei der lappenartige Halteelemente aus dem Hülsenmaterial freigestanzt und in Richtung auf den Meißelschaft hin abgebogen sind.Another embodiment of a round shank chisel is in the EP 0 295 232 shown. Here, the clamping sleeve over its entire circumference a groove which is rolled in the direction of the drill collar. With the thus formed Hütsenmaterial the clamping sleeve engages in the circumferential groove in the chisel shaft. The WO 03/004832 A1 Finally, shows a clamping sleeve in which lobe-like holding elements are punched out of the sleeve material and bent in the direction of the drill collar towards.

Es ist Aufgabe der Erfindung, bei einem Rundschaftmeißel mit Meißelhalter der eingangs erwähnten Art die Halteelemente der Spannhülse so zugestalten, dass sie das Axialspiel reduzieren, die Zentrierung des Schaftes in der Spannhülse so verbessern, dass sich der Schaft in der Spannhülse ohne Beeinträchtigung drehen kann.It is an object of the invention in a round shank chisel with bit holder of the type mentioned the retaining elements of the clamping sleeve so shaped that they reduce the axial play, the centering of the shaft in the clamping sleeve so improve that the shaft can rotate in the collet without interference.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die Halteelemente zwischen zwei quer zur Längsachse der Spannhülse gerichteten Stanzkanten abgeteilt und nach innen eingestanzt und/oder eingedrückt sind, dass sich die Stanzkanten über einen Teil des Umfanges der Spannhülse erstrecken und zueinander einen Abstand aufweisen, der der Breite der Umfangsnut im Schaft des Rundschaftmeißels entspricht, und dass die Halteelemente dem konvexen Nutgrund der der Umfangsnut zugekehrt einen koaxialen, konkaven Zentrierabschnitt bilden.This object is achieved according to the invention in that the holding elements divided between two transverse to the longitudinal axis of the clamping sleeve directed punching edges and stamped and / or indented inwardly, that the punching edges extend over a portion of the circumference of the clamping sleeve and to each other at a distance corresponding to the width of the circumferential groove in the shank of the round shank chisel, and that the holding elements facing the convex groove bottom of the circumferential groove form a coaxial, concave centering.

Die Anpassung der Breite der Halteelemente an die Breite der Umfangsnut im Schaft des Rundschaftmeißels bringt eine Reduzierung des Axialspiels zwischen Spannhülse und Schaft, während die dem konvexen Nutgrund der Umfangsnut mit zugekehrten koaxialen, konkaven Zentrierabschnitten der Halteelemente die Funktionen des Rundschaftmeißels im Meißelhalter optimiert.The adaptation of the width of the holding elements to the width of the circumferential groove in the shank of the round shank chisel brings a reduction of the axial clearance between the clamping sleeve and shank, while the convex groove bottom of the circumferential groove with facing coaxial, concave centering of the holding elements optimizes the functions of the round shank chisel in the bit holder.

Nach einer einfachen Ausführung ist es vorgesehen, dass die Spannhülse drei Halteelemente aufweist, von denen ein Halteelement dem Schlitz der Spannhülse gegenüberliegt, und dass die beiden anderen Halteelemente gegenüber dem einen Halteelement am Umfang der Spannhülse jeweils um ca. 100° versetzt sind. Auf diese Weise wird die Anzahl der Halteelemente auf ein Minimum reduziert. Für die weitere Bemessung der Halteelemente ist vorgesehen, dass die Breite der Umfangsnut und damit die Breite der Halteelemente etwa 1/7 bis 1/6 der axialen Abmessung der Spannhülse gewählt ist und dass sich die konkaven Zentrierabschnitte der Halteelemente über einen Winkelbereich von etwa 30° bis 50° des Umfanges der Spannhülse erstrecken. Damit die Halteelemente keine scharfen Kanten bilden, die die Drehbewegung des Schaftes in der Spannhülse beeinträchtigen können, sieht eine weitere Ausgestaltung vor, dass die Enden der konkaven Zentrieransätze der Halteelemente über eine konvexe Rundung einen Übergangsabschnitt und eine konkave Rundung in die Innenwandung der Spannhülse übergehen, dass die den konkaven Zentrierabschnitten gegenüberliegenden konvexen Außenabschnitte der Spannhülse an den Enden über eine konkave Rundung in die Außenwandung der Spannhülse übergehen.According to a simple embodiment, it is provided that the clamping sleeve has three holding elements, of which a holding element facing the slot of the clamping sleeve, and that the other two holding elements are offset relative to the one holding element on the circumference of the clamping sleeve each by about 100 °. In this way, the number of holding elements is reduced to a minimum. For the further dimensioning of the holding elements is provided that the width of the circumferential groove and thus the width of the holding elements is selected about 1/7 to 1/6 of the axial dimension of the clamping sleeve and that the concave centering of the holding elements over an angular range of about 30 ° extend to 50 ° of the circumference of the clamping sleeve. So that the holding elements do not form sharp edges which may impair the rotational movement of the shank in the clamping sleeve, a further embodiment provides that the ends of the concave centering projections of the holding elements pass over a convex curve a transition section and a concave curve in the inner wall of the clamping sleeve, that the convex outer portions of the clamping sleeve opposite the concave centering sections merge at the ends via a concave curve into the outer wall of the clamping sleeve.

Nach einer Weiterbildung ist vorgesehen, dass die Halteelemente so weit nach innen eingestanzt und/oder eingedrückt sind, dass die konvexen Außenabschnitte, die den konkaven Zentrierabschnitten gegenüberliegen, zu der Innenwandung der Spannhülse beabstandet sind, und dass die Tiefe der Umfangsnut im Schaft des Rundschaftmeißels so bemessen ist, dass die konkaven Zentrierabschnitte der Halteelemente bei in der Bohrung des Meißelhalters verspannten Spannhülse an dem Nutgrund der Umfangsnut anliegen oder einen kleinen Abstand zu diesem einnehmen. Damit wird die Zentrierung des Schaftes des Rundschaftmeißels in der Spannhülse optimiert.According to a further development, it is provided that the holding elements are stamped and / or pressed inwards to such an extent that the convex outer sections facing the concave centering sections are spaced from the inner wall of the clamping sleeve, and the depth of the circumferential groove in the shank of the round shank chisel is so is dimensioned that abut the concave centering of the holding elements clamped in the bore of the chisel holder clamping sleeve on the groove bottom of the circumferential groove or occupy a small distance to this. This optimizes the centering of the shank of the round shank chisel in the clamping sleeve.

Der kritische Punkt der Spannhülse liegt auf der Seite der Meißelspitze zugekehrten Stirnseite der Spannhülse. Um Kollisionen mit dieser Stirnseite zu vermeiden, die zu einer Beeinträchtigung der Drehbewegungen des Rundschaftmeißels führen könnten, sieht eine Ausgestaltung vor, dass die der Meißelspitze zugekehrte Stirnseite der Spannhülse im Abstand zum konischen Einführabschnitt der Bohrung im Meißelhalter steht, der einen konischen Absatz des Meißelkopfes oder einen Zentrieransatz einer zwischen Meißelhalter und Meißelkopf angeordneten Verschleißscheibe aufnimmt.The critical point of the clamping sleeve lies on the side of the chisel tip facing the end of the clamping sleeve. To avoid collisions with this end face, which could lead to an impairment of the rotational movements of the round shank chisel, an embodiment provides that the chisel tip facing end face of the clamping sleeve is at a distance from the conical insertion section of the hole in the chisel holder, which has a conical shoulder of the chisel head or a centering approach a arranged between bit holder and chisel head wear plate receives.

Einen zusätzlich verbesserten Effekt auf die Zentrierung des Schaftes des Rundschaftmeißels in der Spannhülse wird nach einer Weiterbildung dadurch erreicht, dass die Halteelemente in der Mittelquerebene der Spannhülse angeordnet oder symmetrisch zu dieser angeordnet sind, und dass die Spannhülse in zwei um 180° um ihre Längsachse verdrehten axialen Stellungen auf dem Schaft des Rundschaftmeißels aufbringbar und wahlweise in einer der beiden identischen Stellungen darauf festgelegt ist. Dabei wird gleichzeitig der Einbau, das heißt das Aufbringen der Spannhülse auf den Schaft des Rundschaftmeißels in die Bohrung des Meißelhalters erleichtert. Im Übrigen wird damit auch die Zentrierung der der Spannhülse verbessert. Werden zwei oder mehrere, symmetrisch zur Mittelquerebene angeordnete Reihen von Halteelementen verwendet, dann ergibt sich zusätzlich eine besonders stabile Abstützung des Meißelschaftes.An additional improved effect on the centering of the shank of the round shank chisel in the clamping sleeve is achieved according to a development characterized in that the holding elements are arranged in the median transverse plane of the clamping sleeve or arranged symmetrically to this, and that the clamping sleeve rotated in two by 180 ° about its longitudinal axis axial positions on the shank of the round shank chisel applied and optionally set in one of the two identical positions it. At the same time the installation, that is, the application of the clamping sleeve on the shank of the round shank chisel is facilitated in the bore of the chisel holder. Incidentally, this also improves the centering of the clamping sleeve. If two or more, arranged symmetrically to the median transverse plane rows of holding elements used, then in addition results in a particularly stable support of the drill collar.

Das Einsetzen des Rundschaftmeißels in die Bohrung des Meißelhalters wird dadurch begründet, dass die Außenkanten an den beiden Stirnseiten der Spannhülse abgeschrägt sind, wobei die abgeschrägten Außenkanten der Stirnseiten der Spannhülse im Winkel von ca. 30° zur Außenwandung der Spannhülse stehen.The insertion of the round shank chisel in the bore of the chisel holder is justified by the fact that the outer edges are chamfered at the two end faces of the clamping sleeve, wherein the bevelled outer edges of the end faces of the clamping sleeve are at an angle of approximately 30 ° to the outer wall of the clamping sleeve.

Die Erfindung wird anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:

Wie die Fig. 1 bis 3 zeigen, trägt die Spannhülse 10 einen zu der Längsachse 19 parallelen Schlitz 11 und über den Umfang verteilt drei Halteelemente 16, 17, 18. Das Halteelement 16 liegt gegenüber dem Schlitz 11. Die beiden anderen Halteelemente 17 und 18 sind um jeweils etwas a = 100° gegenüber dem Halteelement 16 am Umfang der Spannhülse 10 versetzt. Die Halteelemente 16, 17, 18 sind jeweils durch zwei parallele Stanzkanten 20 und 21 abgeteilt, die quer zur Längsachse 19 gerichtet sind und sich über einen Winkelblech von etwa 30° bis 50° des Umfanges der Spannhülse 10 erstrecken.
Wie insbesondere der Querschnitt nach Fig. 3 zeigt, sind die Halteelemente 16, 17 und 18 nach innen eingestanzt und/oder eingedrückt und bilden einen zum konvexen Nutgrund der Umfangsnut 39 koaxialen, konkaven Zentrierabschnitt 22.As the Fig. 1 to 3 show, the clamping sleeve 10 carries a parallel to the longitudinal axis 19 slot 11 and distributed over the circumference three holding elements 16, 17, 18. The holding element 16 is located opposite the slot 11. The other two holding elements 17 and 18 are each a little something = 100 ° offset relative to the holding element 16 on the circumference of the clamping sleeve 10. The holding elements 16, 17, 18 are each separated by two parallel punching edges 20 and 21, which are directed transversely to the longitudinal axis 19 and extend over an angle plate of about 30 ° to 50 ° of the circumference of the clamping sleeve 10.
As in particular the cross section Fig. 3 shows, the holding elements 16, 17 and 18 are punched and / or pressed inwards and form a convex groove bottom of the circumferential groove 39 coaxial, concave centering 22nd

Die Halteelemente 16, 17 und 18 werden in ihrer Breite durch den Abstand der Stanzkanten 20 und 21 bestimmt und auf die Breite der Umfangsnut 39 im Schaft 31 des Rundschaftmeißels 30 abgestimmt.The holding elements 16, 17 and 18 are determined in their width by the distance of the punching edges 20 and 21 and matched to the width of the circumferential groove 39 in the shaft 31 of the round shank bit 30.

Die konkaven Zentrierungsabschnitte 22 der Halteelemente 16, 17 und 18 gehen an ihren Enden über eine konvexe Rundung 26, einen Übergangsabschnitt und eine konkave Rundung 25 in die Innenwandung der Spannhülse 10 über, während die, den konkaven Zentrierabschnitten 22 gegenüberliegenden konvexen Außenabschnitte der Halteelemente 16, 17 und 18 an ihren Enden über eine konkave Rundung 24, einen Übergangsabschnitt und eine konvexe Rundung 23 in die Außenwandung der Spannhülse 10 übergehen. Damit werden an den eingestanzten und/oder eingedrückten Halteelementen 16, 17 und 18 scharfe Kanten vermieden, die das freie Verdrehen des Schaftes 31 in der Spannhülse 10 und das satte Verspannen der Spannhülse 10 in der Bohrung 41 des Meißelhalters 40 beeinträchtigen können.The concave centering sections 22 of the holding elements 16, 17 and 18 pass at their ends via a convex curve 26, a transition section and a concave curve 25 in the inner wall of the clamping sleeve 10, while the concave centering sections 22 opposite convex outer portions of the holding elements 16, 17 and 18 at their ends over a concave curve 24, a transition section and a convex curve 23 in the outer wall of the clamping sleeve 10 pass. This sharp edges are avoided on the stamped and / or depressed holding elements 16, 17 and 18, which can affect the free rotation of the shaft 31 in the clamping sleeve 10 and the full clamping of the clamping sleeve 10 in the bore 41 of the bit holder 40.

Wie aus Fig. 3 weiter abzuleiten ist, sind die Halteelemente 16, 17, und 18 soweit nach innen eingestanzt und/oder eingedrückt, dass ihre konkaven Zentrierabschnitte 22 bei vorgespannter Spannhülse 10 in der Bohrung 41 des Meißelhalters 40 an dem konvexen Nutgrund der Umfangsnut 39 des Schaftes 31 anliegen oder zu diesem in geringem Abstand stehen, was wiederum der freien Verdrehbarkeit des Schaftes 31 in der Spannhülse 10 zugute kommt. Die Tiefe der Umfangsnut 39 im Schaft 31 des Rundschaftmeißels 30 ist dabei weiterhin so bemessen, dass die konvexen Außenabschnitte der Halteelemente 16, 17 und 18 noch einen kleinen Abstand zur Innenwandung der Spannhülse 10 einnehmen, wie ebenfalls der Fig. 3 zu entnehmen ist. Die Breite der Halteelemente 16, 17 und 18 beträgt etwa 1/7 bis 1/6 der Länge der Spannhülse 10, wie die Fig. 2 zeigt.
Dabei können die Halteelemente 16, 17 und 18, wie bei den bekannten Rundschaftmeißeln mit Meißelhalter im Endbereich von Spannhülse 10 und Schaft 31 angeordnet sein, der der Meißelspitze abgekehrt und mit der Umfangsnut 39 versehen ist.How out Fig. 3 is derived further, the holding elements 16, 17, and 18 are stamped and / or pressed inward so far that their concave centering 22 abut with biased clamping sleeve 10 in the bore 41 of the bit holder 40 on the convex groove bottom of the circumferential groove 39 of the shaft 31 or stand to this at a small distance, which in turn benefits the free rotatability of the shaft 31 in the clamping sleeve 10. The depth of the circumferential groove 39 in the shaft 31 of the round shank bit 30 is further dimensioned so that the convex outer portions of the holding elements 16, 17 and 18 occupy a small distance from the inner wall of the clamping sleeve 10, as well as the Fig. 3 can be seen. The width of the holding elements 16, 17 and 18 is about 1/7 to 1/6 of the length of the clamping sleeve 10, as the Fig. 2 shows.
In this case, the holding elements 16, 17 and 18, as in the known round shank chisels with bit holder in the end of clamping sleeve 10 and shaft 31 may be arranged, which faces away from the chisel tip and provided with the circumferential groove 39.

Um die Zentrierung des Schaftes 31 in der Spannhülse 10 und dessen freie Verdrehbarkeit zu verbessern, können die Halteelemente 16, 17 und 18 auch im Bereich der Mittelquerebene 38 der Spannhülse 10 angeordnet sein und in die in diesem Bereich des Schaftes 31 eingebrachte Umfangsnut 39 eingreifen. Die Spannhülse 10 kann dann in zwei Stellungen auf den Schaft 31 aufgebracht und in eine von zwei identischen Stellungen darauf festgelegt werden. Dies erleichtert den Einbau der Spannhülse 10, da sie vorher nicht in eine ganz bestimmte Stellung zum Schaft 31 gebracht werden muss. Zudem wird die Zentrierung des Schaftes 31 und die freie Verdrehbarkeit desselben verbessert, da sich die Spannhülse 10 in ihrer Längsrichtung weniger verkanten kann.In order to improve the centering of the shaft 31 in the clamping sleeve 10 and its free rotatability, the holding elements 16, 17 and 18 may also be arranged in the region of the median transverse plane 38 of the clamping sleeve 10 and in the in this Area of the shaft 31 inserted circumferential groove 39 engage. The clamping sleeve 10 can then be applied in two positions on the shaft 31 and fixed in one of two identical positions thereon. This facilitates the installation of the clamping sleeve 10, since it does not have to be brought into a specific position to the shaft 31 before. In addition, the centering of the shaft 31 and the free rotatability of the same is improved because the clamping sleeve 10 can tilt less in their longitudinal direction.

Wie Fig. 3 zeigt, sind die Umfangsnut 39 im Schaft 31 und die Halteelemente 16, 17 und 18 so aufeinander abgestimmt, dass auch die der Meißelspitze 37 zugekehrte Stirnseite 12 nicht in den konischen Einführungsabschnitt 42 der Bohrung 41 im Meißelhalter 40 ragt und frei liegt. In den konischen Einführungsabschnitt 42 ragt der Meißelkopf 36 mit einen konischen Absatz 32 des Bundes 33, an den sich die Abzugskehle 34 und der Abzugsbund 35 des Meißelkopfes 36 anschließt. In den Meißelkopf 36 ist die Meißelspitze 37 aus Hartmetall eingesetzt.As Fig. 3 shows, the circumferential groove 39 in the shaft 31 and the holding elements 16, 17 and 18 are coordinated so that even the chisel tip 37 facing end face 12 does not project into the conical insertion portion 42 of the bore 41 in the bit holder 40 and is exposed. In the conical insertion portion 42 of the chisel head 36 projects with a conical shoulder 32 of the collar 33, to which the withdrawal throat 34 and the discharge collar 35 of the chisel head 36 connects. In the chisel head 36, the chisel tip 37 is inserted from hard metal.

Zwischen dem Meißelkopf 36 und dem Meißelhalter 40 kann auch eine Verschleißscheibe angeordnet sein, die mit einem Zentrieransatz in den konischen Einführungsabschnitt 42 der Bohrung 41 im Meißelhalter 40 ragt und so nicht mit der zugekehrten Stirnseite 12 der Spannhülse 10 in Kontakt kommt.Between the chisel head 36 and the chisel holder 40 may also be arranged a wear plate, which protrudes with a spigot in the conical insertion portion 42 of the bore 41 in the chisel holder 40 and so does not come into contact with the facing end face 12 of the clamping sleeve 10.
