- Fig. 1 is a soil cultivation roller for a soil cultivation machine constructed, for example, in the manner of a soil compactor, generally designated 10.
- the soil cultivation roller 10 comprises a roller shell 12 surrounding a roller axis of rotation A with an outer peripheral surface 14.
- a plurality of first change holder parts 16 of change holders generally designated 18 of roller tools generally designated 20 are fixed by welding.
- the first change holder parts 16 are in a plurality of in the direction of Roller axis of rotation A successive rings are arranged one after the other in the circumferential direction, the first change holder parts 16 arranged in rings immediately following one another in the axial direction being arranged offset from one another in the circumferential direction.
- the Fig. 2 shows the tillage roller 10 of the Fig. 1 with the complete roller tools 20.
- these include second change holder parts 22 and, through these, change tools 24 in the form of chisels held on the first change holder parts 16.
- roller tools 20 include roller tools 24 'in the form of padding feet carried on the change holders 18.
- the change holders 18 of the roller tools 20 are fixed directly to the roller shell 12 providing a carrier shell 26.
- a covering jacket constructed, for example, with a plurality of shell segments could be used as the carrier jacket 26, which, if necessary, can be arranged surrounding the roller jacket 12 of such a soil cultivation roller 10.
- the roller tool 20 includes the first change holder part 16, which is made, for example, from a cast or forged component. This has a plate-like attachment area 28 which is fixed to the outer peripheral surface 14 by welding and is adapted to the curved outer peripheral contour of the carrier jacket 16. You recognize in Fig.
- the attachment area 28 essentially in its entire circumferential area of a chamfer 30 is surrounded, so that the first change holder part 16 can be fixed to the carrier jacket 26 or to the outer peripheral surface 14 by a weld seam on the carrier jacket 26 or on the outer peripheral surface 14, which preferably runs completely around the attachment area 28 in the circumferential direction and engages in the chamfer 30.
- a stable, solid bond is thus created between the carrier jacket 26 and the first interchangeable holder part 16.
- the roller tool 20 or its change holder 18 also includes the in Fig. 10 shown second change holder part 22.
- a change holder part receiving recess 32 which is open to one side and in the direction away from the connection area 28, is formed, in which, in the assembled state, the second change holder part 22 is accommodated in such a way that it is flush with the first change holder part Transition between these two interchangeable holder parts 16, 22 is provided and in the transition between these two interchangeable holder parts 16, 22 there are essentially no steps which could lead to damage in particular to the second interchangeable holder part 22.
- breaking projections 38, 40 projecting radially outwards in the circumferential direction or with respect to the roller axis of rotation A are provided , which, particularly when interchangeable tools 24 designed as chisels are used, additionally contribute to the shredding of the soil to be broken.
- a change holder opening is formed in the change holder 18. This is elongated in the direction of an opening longitudinal axis Lo and is therefore open radially outwards with respect to the roller axis of rotation A when the change holder 18 is attached to a carrier jacket 26.
- the change holder opening 42 is delimited in the circumferential direction by the two change holder parts 16, 22.
- the first change holder part 16 delimits the change holder opening 42 in a first peripheral region U 1 .
- the second change holder part 22 delimits the change holder opening 42 in remaining second circumferential area U 1 , which, as the synopsis of Fig. 10 and 22 illustrate this, is significantly smaller than the first circumferential region U 2 .
- the change holder opening 42 formed largely in the first change holder part 16 or the part thereof formed in the first change holder part 16 is open transversely to the opening longitudinal axis Lo, in particular to the change holder part receiving recess 32.
- the change tool 24 or 24 ' is therefore inserted laterally, i.e. transversely with respect to the opening longitudinal axis Lo, into the part of the change holder opening 42 formed in the first change holder part 16 when assembling a roller tool 20.
- a changing tool holding formation is provided on the first changing holder part 16. This comprises a holding projection 46 which projects radially inwards with respect to the opening longitudinal axis Lo and extends, for example, over the first circumferential region U1 .
- a counter-holding formation 51 is formed in association with the changing tool holding formation 44 or the holding projection 46 with a holding recess 50 set back radially inwards with respect to a shaft longitudinal axis Ls.
- the holding recess 50 also has a structure that tapers radially inward with respect to the shaft longitudinal axis Ls, for example conically tapering.
- the holding projection 46 enters the holding recess 50. Due to the interaction of the tapering holding projection 46, which thus creates a wedge effect, with the holding recess 50, the changing tool 24 is closed in the direction of the opening longitudinal axis Lo or the shaft longitudinal axis Ls in the direction of the first changing holder part 16 or its connection area 28, i.e. when attached to a Soil cultivation roller 10 is biased radially inwards with respect to the roller axis of rotation A.
- the changing tool 24 comes with a counter-support area 54 formed on a body area 52 thereof into contact with a changing tool support area 56 formed on the change holder 18.
- the changing tool support area 56 comprises a ring-like changing tool support surface 58 that essentially completely surrounds the changing tool opening 42.
- a first supporting surface part 60 of the changing tool supporting surface is formed on the first changing tool holder part 16, and a second changing tool supporting surface part 62 is formed on the second changing tool holder part 22 .
- the first and second changing tool support surface parts 60, 62 are also dimensioned differently in the circumferential direction around the opening longitudinal axis Lo.
- the second change holder part 22 is fixed to the first change holder part 16 by two fastening elements 64, 66, designed for example as screw bolts.
- Each of these fastening elements 64, 66 comprises an externally threaded shaft 68 with a head 70.
- a fastening member passage opening 72, 74 is formed, through which the externally threaded shaft 68 of a respective fastening member 64, 66 can be passed.
- a fastening element positive engagement opening 76, 78 is formed in the second change holder part 22.
- the fastening member positive engagement openings 76, 78 can be designed as internally threaded openings into which the shafts 68 of the fastening members 64, 66 in the change holder part receiving recess 32 arranged second change holder part 22 can be screwed in in order to clamp the second change holder part 22 firmly against the first change holder part 16.
- extended head receiving areas 80, 82 are provided in the area of the fastening element access openings 72, 74, into which the heads 70 of the fastening elements 64, 66 can be completely immersed.
- the second change holder part 22 therefore essentially serves to press the change tool shank 48 laterally into the part of the change holder opening 42 formed in the first change holder part 16 and thereby press the holding projection 46 of the first change holder part 16 into the holding recess 50 of the change tool shank 48 and thus continue to do so, for example Chisel-shaped changing tool 24 with its counter-support area 54 to press against the changing tool support area 56.
- the counter-support region 54 is essentially provided by a ring-like surface 84 on the changing tool body 52 that surrounds the changing tool shaft 48 and is essentially orthogonal to the shaft longitudinal axis Ls.
- a changing tool 24 'designed as a padding foot is in the Fig. 13 to 15 shown in more detail.
- This also has a changing tool body 52 which provides the padding foot structure, from which the changing tool shaft 48 with the holding recess 50 formed therein extends.
- a surface 84 formed on the changing tool body 52 and essentially surrounding the changing tool shaft 48 with a ring-like structure and, for example, slightly protruding in the direction of the shaft longitudinal axis Ls provides the counter-support region 54 to be supported on the changing tool support surface 58.
- a rotation locking projection 86 is provided on a peripheral side of the changing tool body 52. In the assembled state, this engages over the second change holder part 22 and thus prevents the change tool 24 'from rotating about the shaft longitudinal axis Ls.
- the changing tool shaft 48 When attaching such a changing tool 24 ' designed as a padding foot to the changing holder 18, the changing tool shaft 48 is inserted laterally into the first changing holder part 16, as described above, so that the holding projection 46 and the holding recess 50 occur.
- the second interchangeable holder part 22 is positioned on the interchangeable tool 24' in such a way that the anti-rotation projection 86 already engages over the second interchangeable holder part 22.
- the two change holder parts 16, 22 holding the changing tool together can then be fixed to one another by the fastening members 64, 66.

Es ist die Aufgabe der vorliegenden Erfindung, ein Walzenwerkzeug für eine Bodenbearbeitungswalze einer Bodenbearbeitungsmaschine vorzusehen, bei welchem ein Wechselwerkzeug zuverlässig an einem Wechselhalter festgelegt werden kann und auch nach längerer Betriebsdauer einfach von dem Wechselhalter gelöst werden kann.It is the object of the present invention to provide a roller tool for a soil cultivation roller of a soil cultivation machine, in which a changing tool can be reliably fixed to a changing holder and can be easily detached from the changing holder even after a long period of operation.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Walzenwerkzeug für eine Bodenbearbeitungswalze einer Bodenbearbeitungsmaschine, umfassend einen an einer Außenumfangsseite eines Trägermantels festzulegenden Wechselhalter, wobei der Wechselhalter einen Anbindungsbereich zur festen Anbindung an eine Außenumfangsfläche des Trägermantels und eine in Richtung einer Öffnungslängsachse langgestreckte Wechselhalteröffnung zur Aufnahme eines Wechselwerkzeugschafts eines an dem Wechselhalter lösbar festzulegenden Wechselwerkzeugs umfasst.According to the invention, this object is achieved by a roller tool for a soil cultivation roller of a soil cultivation machine, comprising a change holder to be fixed to an outer circumferential side of a carrier casing, the change holder having a connection area for firmly connecting to an outer circumferential surface of the carrier casing and a change holder opening which is elongated in the direction of an opening longitudinal axis for receiving a changing tool shaft includes a changing tool to be releasably attached to the change holder.
Der Wechselhalter umfasst:
- ein erstes Wechselhalterteil, wobei an dem ersten Wechselhalterteil der Anbindungsbereich vollständig vorgesehen ist,
- ein an dem ersten Wechselhalterteil lösbar anzubringendes zweites Wechselhalterteil, wobei das zweite Wechselhalterteil zusammen mit dem ersten Wechselhalterteil die Wechselhalteröffnung in Umfangsrichtung um die Öffnungslängsachse begrenzt.
- a first interchangeable holder part, the connection area being completely provided on the first interchangeable holder part,
- a second change holder part to be detachably attached to the first change holder part, the second change holder part together with the first change holder part delimiting the change holder opening in the circumferential direction around the opening longitudinal axis.
Bei dem erfindungsgemäß aufgebauten Walzenwerkzeug übernehmen die beiden Wechselhalterteile zusammen die Funktion der stabilen und zuverlässigen Arretierung eines jeweiligen Walzenwerkzeugs an dem Wechselhalter, während nur eines der beiden baulich zueinander unterschiedlich ausgeführten Wechselhalterteile dazu dient, den Wechselhalter fest an einen Trägermantel anzubinden. Dies ermöglicht eine stabile und gegen die im Arbeitsbetrieb auftretenden massiven Einwirkungen resistente Festlegung des Wechselhalters am einem Trägermantel, während ein an einem derartigen Wechselhalter gehaltenes Wechselwerkzeug in einfacher Weise dadurch von diesem gelöst werden kann, dass das nicht an dem Trägermantel angebundene Wechselhalterteil entfernt wird und dadurch das Wechselwerkzeug freigegeben wird.In the roller tool constructed according to the invention, the two change holder parts together take on the function of stable and reliable locking of a respective roller tool on the change holder, while only one of the two change holder parts, which are structurally different from one another, serves to firmly connect the change holder to a carrier jacket. This enables a stable fixation of the change holder on a carrier jacket that is resistant to the massive impacts that occur during work, while a change tool held on such a change holder can be easily detached from it by not being attached to it The changing holder part connected to the carrier jacket is removed and the changing tool is thereby released.
Für eine stabile Halterung eines Wechselwerkzeugs wird vorgeschlagen, dass das erste Wechselhalterteil die Wechselhalteröffnung in Umfangsrichtung um die Öffnungslängsachse in einem ersten Umfangsbereich begrenzt, dass das zweite Wechselhalterteil die Wechselhalteröffnung in Umfangsrichtung um die Öffnungslängsachse in einem zweiten Umfangsbereich begrenzt, und dass der erste Umfangsbereich größer ist als der zweite Umfangsbereich.For a stable holding of a changing tool, it is proposed that the first changing holder part limits the changing holder opening in the circumferential direction around the longitudinal axis of the opening in a first circumferential region, that the second changing holder part limits the changing holder opening in the circumferential direction around the longitudinal axis of the opening in a second peripheral region, and that the first peripheral region is larger as the second scope area.
Um im Arbeitsbetrieb ein Loslösen eines Wechselwerkzeugs von einem Wechselhalter zu verhindern, kann an dem Wechselhalter eine Wechselwerkzeug-Halteformation vorgesehen sein, wobei für einen einfach zu realisierenden Aufbau die Wechselwerkzeug-Halteformation vorzugsweise nur an dem ersten Wechselhalterteil vorgesehen ist.In order to prevent a changing tool from becoming detached from a changing holder during operation, a changing tool holding formation can be provided on the changing tool holder, with the changing tool holding formation preferably only being provided on the first changing holder part for an easy-to-implement structure.
Um über einen größeren Umfangsbereich eine stabile Haltewechselwirkung zwischen einem Wechselhalter und einem Wechselwerkzeug bereitzustellen, kann die Wechselwerkzeug-Halteformation im Wesentlichen in dem ersten Umfangsbereich sich um die Öffnungslängsachse erstreckend ausgebildet sein.In order to provide a stable holding interaction between a change holder and a change tool over a larger circumferential area, the change tool holding formation can be designed to extend around the longitudinal axis of the opening essentially in the first circumferential area.
Das erfindungsgemäße Walzenwerkzeug kann ferner ein Wechselwerkzeug mit einem in der Wechselhalteröffnung aufzunehmenden Wechselwerkzeugschaft umfassen, wobei an dem Wechselwerkzeugschaft eine Gegen-Halteformation zum Eingriff mit der Wechselwerkzeug-Halteformation vorgesehen ist.The roller tool according to the invention can further comprise a changing tool with a changing tool shaft to be received in the changing tool holder opening, a counter-holding formation being provided on the changing tool shank for engagement with the changing tool holding formation.
Ein stabiler Formschluss zwischen einem Wechselhalter und einem daran gehaltenen Wechselwerkzeug kann beispielsweise dadurch erreicht werden, dass die Wechselwerkzeug-Halteformation einen bezüglich der Öffnungslängsachse nach radial innen hervorstehenden Haltevorsprung umfasst, und dass die Gegen-Halteformation eine bezüglich einer Schaftlängsachse des Wechselwerkzeugs nach radial innen zurückgesetzte Halteaussparung umfasst.A stable positive connection between a change holder and a change tool held thereon can be achieved, for example, in that the change tool holding formation comprises a holding projection which protrudes radially inwards with respect to the opening longitudinal axis, and in that the counter-holding formation has a holding recess set back radially inwards with respect to a shaft longitudinal axis of the change tool includes.
Um das nicht an einen Trägermantel angebundene zweite Wechselhalterteil gegen äußere Einwirkungen zu schützen, kann an dem ersten Wechselhalterteil eine Wechselhalterteil-Aufnahmeaussparung zur Aufnahme des zweiten Wechselhalterteils ausgebildet sein.In order to protect the second change holder part, which is not connected to a carrier jacket, against external influences, a change holder part receiving recess for receiving the second change holder part can be formed on the first change holder part.
Eine stabile Verbindung der beiden Wechselhalterteile miteinander kann beispielsweise dadurch erreicht werden, dass das zweite Wechselhalterteil durch eine Mehrzahl von Befestigungsorganen an dem ersten Wechselhalterteil festzulegen ist.A stable connection of the two interchangeable holder parts to one another can be achieved, for example, in that the second interchangeable holder part is to be fixed to the first interchangeable holder part by a plurality of fastening elements.
Hierzu kann in wenigstens einem Wechselhalterteil von erstem Wechselhalterteil und zweitem Wechselhalterteil in Zuordnung zu wenigstens einem Befestigungsorgan eine Befestigungsorgan-Durchgriffsöffnung vorgesehen sein, und in dem anderen Wechselhalterteil von erstem Wechselhalterteil und zweitem Wechselhalterteil kann in Zuordnung jeder Befestigungsorgan-Durchgriffsöffnung des einen Wechselhalterteils eine Befestigungsorgan-Formschlusseingriffsöffnung vorgesehen sein.For this purpose, a fastening member access opening can be provided in at least one change holder part of the first change holder part and the second change holder part in association with at least one fastening element, and in the other change holder part of the first change holder part and the second change holder part, a fastening element positive engagement opening can be provided in association with each fastening element access opening of the one change holder part be provided.
Eine hohe Stabilität des Verbundes kann dadurch gewährleistet werden, dass in dem einen Wechselhalterteil, vorzugsweise dem ersten Wechselhalterteil, beidseits der Wechselhalteröffnung jeweils wenigstens eine Befestigungsorgan-Durchgriffsöffnung vorgesehen ist.A high level of stability of the composite can be ensured by providing at least one fastening member access opening in one change holder part, preferably the first change holder part, on both sides of the change holder opening.
Um eine definierte Positionierung eines Wechselwerkzeugs bezüglich eines Wechselhalters zu unterstützen, kann an dem Wechselhalter ein von dem Anbringungsbereich abgewandt liegender Wechselwerkzeug-Abstützbereich vorgesehen sein.In order to support a defined positioning of a changing tool with respect to a changing holder, a changing tool support area facing away from the attachment area can be provided on the changing holder.
Hierzu kann der Wechselwerkzeug-Abstützbereich eine die Wechselhalteröffnung vorzugsweise im Wesentlichen vollständig umgebende Wechselwerkzeug-Abstützfläche umfassen, wobei an dem ersten Wechselhalterteil ein erster Wechselwerkzeug-Abstützflächenteil vorgesehen ist und an dem zweiten Wechselhalterteil ein zweiter Wechselwerkzeug-Abstützflächenteil vorgesehen ist.For this purpose, the changing tool support area can comprise a changing tool support surface which preferably essentially completely surrounds the changing tool holder opening, a first changing tool supporting surface part being provided on the first changing tool holder part and a second changing tool supporting surface part being provided on the second changing tool holder part.
Um im Arbeitsbetrieb zu einem starken Verschleiß führende Relativbewegungen zwischen einem Wechselwerkzeug und einem Wechselhalterteil zu vermeiden, wird vorgeschlagen, dass bei mit der Gegen-Halteformation in Eingriff stehender Wechselwerkzeug-Halteformation das Wechselwerkzeug in Anlage an dem Wechselwerkzeug-Abstützbereich vorgespannt ist.In order to avoid relative movements between a changing tool and a changing holder part that lead to severe wear during operation, it is proposed that when the changing tool holding formation is in engagement with the counter-holding formation, the changing tool is biased into contact with the changing tool support area.
Die Erfindung betrifft ferner eine Bodenbearbeitungswalze, umfassend eine Mehrzahl von erfindungsgemäß aufgebauten Walzenwerkzeugen, wobei die ersten Wechselhalterteile der Walzenwerkzeuge an einen Trägermantel durch Verschweißen, vorzugsweise jeweils eine den Anbindungsbereich eines jeweiligen ersten Wechselhalterteils im Wesentlichen unterbrechungsfrei umgebende Schweißnaht, fest angebunden sind.The invention further relates to a soil cultivation roller, comprising a plurality of roller tools constructed according to the invention, wherein the first interchangeable holder parts of the roller tools are firmly connected to a carrier shell by welding, preferably in each case a weld seam which surrounds the connection area of a respective first interchangeable holder part in a substantially uninterrupted manner.
Der Trägermantel kann beispielsweise ein Walzenmantel der Bodenbearbeitungswalze sein. Bei einer alternativen Ausgestaltung kann der Trägermantel ein den Walzenmantel der Bodenbearbeitungswalze umgebend anzuordnender Umkleidungsmantel sein, welcher zur Durchführung eines entsprechenden Bodenbearbeitungsvorgangs einen mit im Wesentlichen unstrukturierter Außenumfangsfläche ausgebildeten Walzenmantel einer Bodenbearbeitungswalze umgebend angeordnet wird.The carrier casing can be, for example, a roller casing of the soil cultivation roller. In an alternative embodiment, the carrier jacket can be a cladding jacket to be arranged surrounding the roller jacket of the soil cultivation roller, which is arranged surrounding a roller jacket of a soil cultivation roller which is designed with a substantially unstructured outer peripheral surface in order to carry out a corresponding soil cultivation process.
Die Erfindung betrifft ferner eine Bodenbearbeitungsmaschine mit wenigstens einer erfindungsgemäß aufgebauten Bodenbearbeitungswalze.The invention further relates to a soil cultivation machine with at least one soil cultivation roller constructed according to the invention.
Die Erfindung betrifft ferner ein Verfahren zur Anbringung eines Wechselwerkzeugs an einem Wechselhalter eines erfindungsgemäß aufgebauten Walzenwerkzeugs, vorzugsweise an einer erfindungsgemäß aufgebauten Bodenbearbeitungswalze oder einer erfindungsgemäß aufgebauten Bodenbearbeitungsmaschine, umfassend die Maßnahmen:
- a) bei von dem ersten Wechselhalterteil entferntem zweiten Wechselhalterteil, Einsetzen eines Wechselwerkzeugschafts des Wechselwerkzeugs in einen in dem ersten Wechselhalterteil ausgebildeten Teil der Wechselhalteröffnung,
- b) bei oder nach der Maßnahme a), Anbringen des zweiten Wechselhalterteils am ersten Wechselhalterteil.
- a) with the second change holder part removed from the first change holder part, inserting a change tool shaft of the change tool into a part of the change holder opening formed in the first change holder part,
- b) during or after measure a), attaching the second interchangeable holder part to the first interchangeable holder part.
Bei der Maßnahme a) kann der Wechselwerkzeugschaft durch Bewegen quer zur Öffnungslängsachse der Wechselhalteröffnung in den in dem ersten Wechselhalterteil ausgebildeten Teil der Wechselhalteröffnung eingesetzt werden.In measure a), the changing tool shaft can be inserted into the part of the changing holder opening formed in the first changing holder part by moving transversely to the longitudinal axis of the opening of the changing holder opening.
Anders als bei aus dem Stand der Technik bekannten Walzenwerkzeugen, wird erfindungsgemäß ein Wechselwerkzeug nicht durch Bewegen in Richtung einer Schaftlängsachse in eine zugehörige Wechselhalteröffnung eingesetzt, sondern durch Bewegen quer, beispielsweise im Wesentlichen orthogonal zur Schaftlängsachse, wobei gegebenenfalls gleichzeitig auch ein in Richtung der Schaftlängsachse wirkender Formschluss zwischen dem Wechselhalterteil und dem Wechselwerkzeug erzeugt werden kann.Unlike roller tools known from the prior art, according to the invention a changing tool is not inserted into an associated change holder opening by moving in the direction of a shaft longitudinal axis, but rather by moving transversely, for example essentially orthogonally to the shaft longitudinal axis, whereby at the same time, if necessary, also acting in the direction of the shaft longitudinal axis Positive connection can be created between the change holder part and the change tool.

Ein erster Abstützflächenteil 60 der Wechselwerkzeug-Abstützfläche ist dabei am ersten Wechselhalterteil 16 ausgebildet, und ein zweiter Wechselwerkzeug-Abstützflächenteil 62 ist am zweiten Wechselhalterteil 22 ausgebildet. Entsprechend der unterschiedlichen Erstreckungslängen der ersten und zweiten Umfangsbereiche U1, U2 um die Öffnungslängsachse LO sind auch die ersten und zweiten Wechselwerkzeug-Abstützflächenteile 60, 62 in Umfangsrichtung um die Öffnungslängsachse Lo unterschiedlich dimensioniert.The changing
Die Festlegung des zweiten Wechselhalterteils 22 am ersten Wechselhalterteil 16 erfolgt durch zwei beispielsweise als Schraubbolzen ausgebildete Befestigungsorgane 64, 66. Jedes diese Befestigungsorgane 64, 66 umfasst einen Außengewindeschaft 68 mit einem Kopf 70. In Zuordnung zu jedem Befestigungsorgan 64, 66 ist im ersten Wechselhalterteil 18 eine Befestigungsorgan-Durchgriffsöffnung 72, 74 ausgebildet, durch welche der Außengewindeschaft 68 eines jeweiligen Befestigungsorgans 64, 66 hindurchgeführt werden kann. Ferner ist in Zuordnung zu jedem Befestigungsorgan 64, 66 bzw. jeder Befestigungsorgan-Durchgriffsöffnung 72, 74 im ersten Wechselhalterteil 16 eine Befestigungsorgan-Formschlusseingriffsöffnung 76, 78 im zweiten Wechselhalterteil 22 ausgebildet. Die Befestigungsorgan-Formschlusseingriffsöffnungen 76, 78 können als Innengewindeöffnungen ausgebildet sein, in welche die Schäfte 68 der Befestigungsorgane 64, 66 bei in der Wechselhalterteil-Aufnahmeaussparung 32 angeordnetem zweitem Wechselhalterteil 22 eingeschraubt werden können, um auf diese Art und Weise das zweite Wechselhalterteil 22 fest gegen das erste Wechselhalterteil 16 zu verspannen.The second
Um die Befestigungsorgane 64, 66 vollständig im Wechselhalter 18 aufnehmen zu können, sind im Bereich der Befestigungsorgan-Durchgriffsöffnungen 72, 74 erweiterte Kopfaufnahmebereiche 80, 82 vorgesehen, in welche die Köpfe 70 der Befestigungsorgane 64, 66 vollständig eintauchen können.In order to be able to accommodate the
