Description
Technisches UmfeldTechnical environment
Die Erfindung betrifft eine Vorrichtung zum Greifen, Halten und Freigeben von Stangenmaterial für die automatische Herstellung von Drehteilen mit einem Tragkörper, an dem mindestens zwei zwischen zwei Endpositionen zueinander bewegliche Greifelemente angeordnet sind.The invention relates to a device for gripping, holding and releasing rod material for the automatic production of turned parts with a support body, are arranged on the at least two mutually between two end positions movable gripping elements.
Stand der TechnikState of the art
Die eingangs beschriebene Vorrichtung wird üblicherweise auch als Stangengreifer bezeichnet und am Werkzeughalter einer Bearbeitungsmaschine vorzugsweise einer Drehmaschine angeordnet. Drehmaschinen sind oftmals so ausgestaltet, dass das für die Herstellung von Drehteilen notwendige Material als Stangenmaterial in der Z-Achse der Drehmaschine programmgesteuert aus einer Mittelbohrung des Backenfutters herausgezogen wird. Zum Zweck des Greifens und Haltens sind Vorrichtungen der gattungsgemäßen Art bekannt, bei der beispielsweise drei konzentrisch zueinander angeordnete Greifbacken oder Haken auf einem Tragkörper angeordnet sind, die in geeigneter Weise aufeinander zu bewegt werden können und auf diese Weise das Ende des Stangenmaterials greifen, halten und aus dem Backenfutter herausziehen können.The device described at the beginning is usually also referred to as a bar gripper and arranged on the tool holder of a processing machine, preferably a lathe. Lathes are often designed so that the necessary for the production of turned parts material is pulled out as a rod material in the Z-axis of the lathe programmatically from a central bore of the jaw chuck. For the purpose of gripping and holding devices of the generic type are known in which, for example, three concentrically arranged gripping jaws or hooks are arranged on a support body, which can be moved toward each other in a suitable manner and in this way grab the end of the rod material, hold and can pull out of the jaw food.
Nach Abschluss dieses Vorganges werden die Greifbacken auseinandergefahren und das Stangenmaterial freigegeben. Für die Herstellung der einzelnen Drehteile wird das Stangenmaterial anschließend in der Spannbacke der Drehmaschine gehalten.After completion of this process, the jaws are moved apart and released the rod material. For the production of the individual turned parts, the bar material is subsequently held in the clamping jaw of the lathe.
Nachteil der beschriebenen Konstruktion ist es, dass die Greifbacken in ihrer Position zueinander einzeln eingestellt werden müssen, um entsprechende unterschiedliche Durchmesser von zu bearbeitenden Stangenmaterial halten zu können. Dies ergibt sich aus der Tatsache, dass der Spannweg der einzelnen Greifbacken konstruktiv begrenzt sein muss, um Beschädigungen des äußeren Umfanges des Stangenmaterials durch zu hohe Spannkräfte zu vermeiden.Disadvantage of the construction described is that the gripping jaws must be set individually in their position to each other to hold corresponding different diameters of machined rod material can. This results from the fact that the clamping path of the individual gripping jaws must be structurally limited in order to avoid damage to the outer circumference of the rod material due to excessive clamping forces.
Darüber hinaus besteht bei diesen Vorrichtungen die Problematik, dass aus dem Stangenmaterial gearbeitete Werkstücke, welche ganz knapp am Backenfutter abgestochen werden, nur noch einen kleinen Stumpf des Stangenmaterials aus dem Backenfutter herausragen lassen. Übliche Stangengreifer sind oftmals nicht in der Lage, dieses nur wenig aus dem Backenfutter herausragende Stangenmaterial aus dem Backenfutter herauszuziehen.In addition, there is the problem with these devices that machined from the bar material workpieces that are tapped very close to the jaw lining, only a small stump of the bar material protrude from the jaw chuck. Common pole grippers are often unable to extract this rod material, which protrudes only slightly from the jaw chuck, out of the jaw chuck.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ausgehend von den aus dem Stand der Technik bekannten Entwicklungen deren Nachteile zu beseitigen und eine kompakte Vorrichtung zum Greifen, Halten und Freigeben von Stangenmaterial bereitzustellen, die Beschädigungen des Endbereiches des zu greifenden Stangenmaterials vermeidet und die mit einfachen Mitteln auf unterschiedliche Durchmesser von zu bearbeitendem Stangenmaterial einstellbar ist. Darüber hinaus soll auch wenig aus einem Backenfutter herausstehendes Stangenmaterial zuverlässig ergriffen und sicher gehalten werden können und der konstruktive Aufbau der Vorrichtung einfach und somit kostengünstig sein.The invention has for its object, on the basis of the developments known from the prior art to eliminate their disadvantages and to provide a compact device for gripping, holding and releasing of bar stock, which avoids damage to the end portion of the rod material to be gripped and the simple means different diameter of machined rod material is adjustable. In addition, little projecting out of a jaw feed bar material should be reliably taken and kept safe and the structural design of the device can be simple and therefore inexpensive.
Lösung der AufgabeSolution of the task
Diese Aufgabe wird erfindungsgemäß für eine Vorrichtung zum Greifen, Halten und Freigeben von Stangenmaterial mit den gattungsbildenden Merkmalen des Anspruches 1 durch die im kennzeichnenden Teil des Anspruches offenbarte technische Lehre gelöst.This object is achieved for a device for gripping, holding and releasing rod material with the generic features of
Erfindungswesentlich ist dabei, dass an den Greifelementen jeweils parallel beabstandet mindestens zwei um jeweils eine Mittelachse drehbar gelagerte Rollenkörper dergestalt angeordnet sind, dass die Mittelachsen der Rollenkörper im wesentlichen parallel zur Längsachse des Stangenmaterials ausgerichtet sind.It is essential to the invention that at least two roller bodies rotatably mounted about a respective central axis are arranged on the gripping elements in such a way that the center axes of the roller bodies are aligned essentially parallel to the longitudinal axis of the bar material.
Durch die neuartige Gestaltung der Greifelemente sind diese in der Lage, seitlich an das freie Ende des Stangenmaterials heranzufahren, wobei die Greifelemente beim Kontakt mit dem Stangenmaterial aus ihrer zueinander festgelegten Endposition elastisch gegen eine Federvorrichtung sich auf einer gemeinsamen Laufbahn auseinander bewegen. Die drehbar gelagerten Rollenkörper rollen dabei auf der Außenfläche des Stangenmaterials ab, so dass Beschädigungen vermieden werden.Due to the novel design of the gripping elements they are able to move laterally to the free end of the bar material, wherein the gripping elements when in contact with the bar material from their mutually fixed end position elastically move against a spring device on a common career apart. The rotatably mounted roller body roll while on the outer surface of the rod material, so that damage can be avoided.
Ist der zur Vorrichtung gehörende Tragkörper mit den Greifelementen mittig zur Längsachse des Stangenmaterials gefahren, wobei die Rollenkörper das Ende des Stangenmaterials umgreifen, kann das Stangenmaterial durch eine in Z-Richtung der Drehmaschine vonstatten gehende Bewegung aus dem Backenfutter herausgezogen werden, bis eine Position für die Fertigung des nächsten Drehteiles erreicht ist.Is the belonging to the device support body with the gripping elements moved centrally to the longitudinal axis of the rod material, wherein the roller body embrace the end of the rod material, the rod material can be pulled out by a Z-direction of the lathe vonstatten going movement of the jaw chuck until a position for the Production of the next rotary part is reached.
Danach wird der Tragkörper mit den Greifelementen wieder seitlich aus dem Arbeitsbereich der Drehmaschine herausgefahren. Hierzu bewegen sich die Greifelemente etwas auseinander und fahren dann federbelastet nach Freigabe des Endes des Stangenmaterials wieder in ihre zueinander eingestellte Endposition. Die Federwirkung, die die Greifelemente in ihrer zueinander ausgerichteten Endposition hält, kann eingestellt werden, so dass immer eine geeignete Anpresskraft zum Herausziehen des Stangenmaterials gegeben ist, gleichzeitig jedoch bei empfindlichen Oberflächen nicht zu große Anpresskräfte der Rollenkörper vorhanden sind.Thereafter, the support body is moved out laterally with the gripping elements from the work area of the lathe. For this purpose, the gripping elements move slightly apart and then spring loaded after release of the end of Rod material back to their adjusted end position. The spring action, which holds the gripping elements in their aligned end position, can be adjusted, so that there is always a suitable contact force for pulling the rod material is given, but not too large pressing forces of the roller body are present at sensitive surfaces.
Besondere Ausgestaltungen des Gegenstandes der Erfindung ergeben sich zusätzlich aus den auf den Hauptanspruch bezogenen Merkmalen der Unteransprüche.Particular embodiments of the subject matter of the invention will become apparent from the features of the dependent claims related to the main claim.
Es hat sich insbesondere als vorteilhaft erwiesen, wenn die Greifelemente jeweils in einer gemeinsamen Führungsnut im Tragkörper verschieblich sind. Die gemeinsame Führungsnut ist zum einen kostengünstig in den Tragkörper einbringbar und gewährleistet darüber hinaus eine definierte Beweglichkeit der Greifelemente zueinander. Zur Befestigung der Greifelemente in der Führungsnut kann in dieser zu jedem Greifelement korrespondierend ein Nutstein angeordnet sein.It has proven to be particularly advantageous if the gripping elements are each displaceable in a common guide groove in the support body. The common guide is cost-effectively introduced into the support body and also ensures a defined mobility of the gripping elements to each other. To fix the gripping elements in the guide groove, a sliding block can be arranged correspondingly to each gripper element in this.
Um je nach Stangenmaterial ausreichende Haltekräfte durch die Anpressung der Rollenkörper an der Umfangsfläche des Stangenmaterials zu gewährleisten, kann es darüber hinaus zweckmäßig sein, wenn die Rollenkörper an ihrer Umfangsfläche eine Strukturierung aufweisen. Diese Strukturierung kann aus einer Mehrzahl von in Richtung der Mittellängsachse der Rollenkörper nebeneinander angeordneten konzentrischen Rillen bestehen. Zur leichteren Austauschbarkeit der Rollenkörper können diese darüber hinaus an den Greifelementen mittels einer Verschraubung festgelegt sein, durch die auch die Drehbarkeit der Rollenkörper gewährleistet ist.In order to ensure, depending on the rod material sufficient holding forces by the contact pressure of the roller body on the peripheral surface of the rod material, it may also be useful if the roller body have structuring on its peripheral surface. This structuring can consist of a plurality of concentric grooves arranged next to one another in the direction of the central longitudinal axis of the roller bodies. For ease of interchangeability of the reel body, these can also be fixed to the gripping elements by means of a screw through which the rotation of the roller body is ensured.
Eine andere Art der Strukturierung kann in einer Diamantstaubbeschichtung der Umfangsfläche der Rollenkörper bestehen.Another type of structuring may consist in a diamond dust coating of the peripheral surface of the roller body.
Es hat sich darüber hinaus als zweckmäßig erwiesen, am Tragkörper für jedes Greifelement eine Messskala zur Einstellung des Abstandes der Greifelemente zueinander anzuordnen. Diese Messskala weist ausgehend von einem mittigen Nullpunkt in zwei beabstandet zueinander angeordneten Bereichen jeweils Skalenwerte auf, an denen der Benutzer der Vorrichtung die Stellung der Greifelemente ablesen kann. Auf diese Weise lassen sich innerhalb einer extrem kurzen Zeitspanne unterschiedliche Abstände der Greifelemente zueinander exakt einstellen. In der Praxis hat sich gezeigt, dass diese Einstellung in weniger als einer Minute vorgenommen werden kann.It has also proved to be useful to arrange a measuring scale for adjusting the distance of the gripping elements to each other on the support body for each gripping element. Starting from a central zero point in two spaced-apart regions, this measuring scale has in each case scale values at which the user of the device can read the position of the gripping elements. In this way, different distances of the gripping elements to each other can be set exactly within an extremely short period of time. In practice it has been found that this adjustment can be made in less than a minute.
Zweckmäßig kann darüber hinaus sein, Tragkörper, Greifelemente und Rollenkörper aus Aluminium herzustellen. Durch diese Maßnahme ist die erfindungsgemäße Vorrichtung besonders leicht, wodurch die Gewichtsbelastung am Revolver der Drehmaschine herabgesetzt wird.In addition, it can be expedient to produce support bodies, gripping elements and roller bodies made of aluminum. By this measure, the device according to the invention is particularly easy, whereby the weight load on the revolver of the lathe is reduced.
