Description

Zwischenflansch für eine WerkzeugmaschineIntermediate flange for a machine tool
Stand der TechnikState of the art
Die Erfindung geht aus von einem Zwischenflansch für eine Werkzeugmaschine zur Lagerung von Maschinenteilen nach dem Oberbegriff des Anspruchs 1.The invention relates to an intermediate flange for a machine tool for the storage of machine parts according to the preamble of claim 1.
Allgemein sind als Zwischenflansch ausgebildete Bauteile für eine Werkzeugmaschine, insbesondere für Bohr- und/oder Meißelhämmer in Pistolenbauweise bekannt, die zur Lagerung der Schlagwerkteile und/oder der Motorachse dienen. Der Zwischenflansch ist dabei vorzugsweise aus einem wärmeleitenden Material, beispielsweise aus einer Aluminiumlegierung, aus Magnesium usw., hergestellt und bietet mechanische Festigkeit bei relativ hoher Arbeitstemperatur. Gleichzeitig wird durch diese Konstruktion Wärme aus dem Getriebereich abgeleitet und durch die Kühlluft des Motors abgeführt. Die hierfür erforderliche Konstruktion ist relativ komplex. Außerdem wird die herkömmliche Konstruktion in Druckgusstechnik hergestellt, wobei eine konstante Wandstärke anzustreben ist. Die Wandstärke der herkömmlichen Konstruktion wird dabei durch den am höchsten belasteten Bereich definiert, so dass ein unnötiger Materialeinsatz erfolgt. Die nachteilige Folge davon ist eine relativ aufwändige und schwere Konstruktion.In general, designed as an intermediate flange components for a machine tool, especially for drilling and / or chisel hammers in pistol design known, which serve for the storage of percussion parts and / or the motor axis. The intermediate flange is preferably made of a thermally conductive material, such as an aluminum alloy, magnesium, etc., and provides mechanical strength at relatively high operating temperature. At the same time, this design dissipates heat from the transmission area and dissipates it through the cooling air of the engine. The required construction is relatively complex. In addition, the conventional construction is made in die-casting technique, with a constant wall thickness is desirable. The wall thickness of the conventional construction is defined by the highest loaded area, so that an unnecessary use of material takes place. The adverse consequence of this is a relatively complex and heavy construction.
Vorteile der ErfindungAdvantages of the invention
Es wird vorgeschlagen, dass der erfindungsgemäßeIt is proposed that the inventive
Zwischenflansch eine Außenwand mit einer gitterförmigen Stützkonstruktion aufweist. Vorteilhafterweise ist ein geringer Materialeinsatz erforderlich. Gleichzeitig ist eine Gewichtsreduzierung des Zwischenflansches möglich. Die Stützkonstruktion kann dabei durch massive, sich kreuzende Stege gebildet sein. Daraus ergibt sich eine hohe Torsions- und Biegesteifigkeit. Es kann eine belastbare Konstruktion mit hoher Leistungsfähigkeit bei gleichzeitiger Reduzierung des Gewichts zur Verfügung gestellt werden, die außerdem eine gute Wärmeleitfähigkeit aufweist.Intermediate flange has an outer wall with a grid-shaped support structure. Advantageously, a smaller one Material required. At the same time a weight reduction of the intermediate flange is possible. The support structure can be formed by massive, intersecting webs. This results in a high torsional and bending stiffness. It can be a heavy-duty construction with high performance while reducing the weight are provided, which also has a good thermal conductivity.
In einer besonders vorteilhaften Ausführungsform weist der erfindungsgemäße Zwischenflansch eine Außenwand mit einer wabenartigen und/oder rautenförmigen Struktur auf, wodurch vorteilhafterweise der Materialeinsatz reduziert werden kann. Je nach Anwendungsfall und Erzeugungstyp kann die wabenartige und/oder rautenförmige Struktur unregelmäßig ausgebildet sein. Diese Konstruktion ist insbesondere für eine y gusstechnische Herstellung geeignet, wobei die Stege als Gusskanäle dienen können. Je nach den gestellten Anforderungen kann durch die Höhe der Stege gezielt die Steifigkeit des Bauteils beeinflusst werden.In a particularly advantageous embodiment, the intermediate flange according to the invention has an outer wall with a honeycomb-like and / or diamond-shaped structure, whereby advantageously the use of material can be reduced. Depending on the application and generation type, the honeycomb-like and / or diamond-shaped structure may be irregular. This construction is particularly suitable for a y-cast production, the webs can be used as sprues. Depending on the requirements, the height of the webs can specifically influence the rigidity of the component.
Um ein prozesssicheres Gießen des erfindungsgemäßen Zwischenflansches zu ermöglichen, kann ein zwischen den Stegen der Konstruktion liegender Bereich materialgefüllt sein. Dies ist zwar nicht aus Festigkeitsgründen erforderlich, vereinfacht jedoch die Herstellung der Bauteile. Vorzugsweise ist der materialgefüllte Bereich dünnwandiger als die Stege ausgebildet, um eine weitere Gewichtsreduzierung zu ermöglichen. Insgesamt wird durch die erfindungsgemäße Konstruktion eine hohe Festigkeit bei geringem Materialeinsatz und somit geringem Eigengewicht erzielt. Alternativ können zwischen den Stegen auch Hohlräume ausgebildet sein.In order to enable a process-reliable casting of the intermediate flange according to the invention, a region lying between the webs of the construction can be material-filled. Although this is not required for reasons of strength, but simplifies the manufacture of the components. Preferably, the material-filled region is formed thinner wall than the webs to allow further weight reduction. Overall, the inventive construction high strength at low Material use and thus achieved low weight. Alternatively, cavities can also be formed between the webs.
Es kann vorgesehen sein, dass zwischen dem materialgefüllten Bereich und den Stegen Hohlräume ausgebildet sind. Dadurch bildet die Außenwand des erfindungsgemäßen Zwischenflansches eine möglichst große Oberfläche, wodurch günstigerweise mehr Wärme aus dem Getriebebereich aufgenommen werden kann als bei einer glatten Oberfläche der Außenwand. Dadurch wird eine optimale Kühlwirkung erzielt.It can be provided that cavities are formed between the material-filled region and the webs. As a result, the outer wall of the intermediate flange according to the invention forms as large a surface as possible, whereby advantageously more heat can be absorbed from the transmission area than with a smooth surface of the outer wall. As a result, an optimal cooling effect is achieved.
Femer können mit dem erfindungsgemäßen Zwischenflansch vorteilhafterweise unterschiedliche Lagerstellen in einem Bauteil vereinheitlicht werden. Es kann vorgesehen sein, dass die Stützkonstruktion zwischen wenigstens zwei sich gegenüberliegenden Stirnseiten angeordnet ist, die eine Lagerstelle für einen Anker eines elektrischen Antriebsmotors und/oder ein Antriebslager und/oder eine Lagerstelle für Rasthülsen aufweisen können. Dabei können die Lagerstelle für den Anker und eine Zentrierung zum Motorgehäuse in einem Stirnflächenbereich angeordnet sein und koaxial zueinander liegen. Sie sind dabei sozusagen in einer „Ebene" angeordnet, in der auch eine Dichtung zum Abdichten des Getriebes angeordnet sein kann, die das notwendige Schmiermittel enthält.Furthermore, advantageously different bearing points in a component can be standardized with the intermediate flange according to the invention. It can be provided that the support structure is arranged between at least two opposite end faces, which may have a bearing point for an armature of an electric drive motor and / or a drive bearing and / or a bearing point for snap-on sleeves. In this case, the bearing point for the armature and a centering to the motor housing may be arranged in an end face region and are coaxial with each other. They are arranged so to speak in a "plane" in which a seal for sealing the transmission can be arranged, which contains the necessary lubricant.
Auf der getriebeseitigen, der einen Stirnseite gegenüberliegenden zweiten Stirnseite des Zwischenflansches kann die Lagerung einer Rasthülse und/oder die Lagerstelle für ein Antriebslager angeordnet sein. Die Rasthülse erfordert vorzugsweise eine stabile Lagerung und Anbindung, um die Kräfte, die beim Arbeiten mit der Werkzeugmaschine entstehen, aufnehmen bzw. dämpfen zu können. Diese Kräfte sind z.B. der Anpressdruck des Anwenders, die Abstützkräfte aus dem Schlagwerk, das Drehmoment und die Hebelkräfte, welche durch das Werkzeug in die Maschine eingeleitet werden. Durch die waben- und/oder rautenförmige Struktur des erfindungsgemäßen Zwischenflansches kann eine Bauteilsteifigkeit erzielt werden, die diesen Anforderungen gerecht wird.On the transmission side, the opposite end face of a second end face of the intermediate flange, the storage of a latching sleeve and / or the bearing point can be arranged for a drive bearing. The locking sleeve preferably requires stable storage and connection to absorb or dampen the forces that arise when working with the machine tool. These forces are, for example, the contact pressure of the user, the support forces from the impact mechanism, the torque and the lever forces, which are introduced by the tool into the machine. By the honeycomb and / or diamond-shaped structure of the intermediate flange according to the invention, a component stiffness can be achieved, which meets these requirements.
In einer besonders bevorzugten Ausführungsform kann die Lagerung der Rasthülse rohrförmig ausgebildet und die Lagerstelle für das Antriebslager auf einer dritten, seitlich versetzten Stirnseite angeordnet sein. Diese Ausführungsform ist aus Bauraumgründen insbesondere für Werkzeugmaschinen in Pistolenbauweise geeignet, wobei das Antriebslager als Taumellager für ein Schlagwerk ausgebildet sein kann. Es kann jedoch auch vorgesehen sein, eine für das Taumellager erforderliche Zwischenwelle im erfindungsgemäßen Zwischenflansch zu lagern. Für die Aufnahme der einwirkenden Radialbelastung kann insbesondere ein Kugellager vorgesehen sein. Diese Lagerung kann auch als Lagersitz ausgebildet sein und gleichzeitig die Aufnahme der ersten Getriebestufe (Ankerdrehzahl/Schlagzahl) bilden. Diese Lagerstelle kann vorteilhafterweise die entstehenden Übertragungsmomente bzw. Kräfte sowie die rückwirkenden Kräfte aus dem Schlagwerk aufnehmen.In a particularly preferred embodiment, the mounting of the detent sleeve can be tubular and the bearing point for the drive bearing can be arranged on a third, laterally offset end face. This embodiment is suitable for space reasons, especially for machine tools in pistol design, wherein the drive bearing can be designed as a swash bearing for a striking mechanism. However, it can also be provided to store a required for the swash bearing intermediate shaft in the intermediate flange according to the invention. For receiving the acting radial load, in particular a ball bearing can be provided. This bearing can also be designed as a bearing seat and at the same time form the receptacle of the first gear stage (armature speed / stroke rate). This bearing can advantageously absorb the resulting transmission moments or forces and the retroactive forces from the percussion.
