Abstract
Description
Die Erfindung beschreibt eine Vorrichtung zum gleichzeitigen Entgraten und/oder Oberflächenbearbeiten der Ober- und Unterseite von Werkstücken.The invention describes a device for simultaneous deburring and / or surface machining of the top and bottom of workpieces.
Bei jedem spanabhebenden Bearbeitungsprozess entsteht durch die plastische Materialumformung an den Werkstückkanten ein Grat, der in der Regel unerwünscht ist, da die Funktion des Produktes beeinträchtigt werden kann. Die Gratentstehung ist durch konstruktionstechnische Maßnahmen minimier- aber nur selten ganz vermeidbar. Entgraten ist eine Oberflächenbearbeitungsart, welche die im vorhergehenden Bearbeitungsprozess entstandenen Grate entfernt.With every machining process, plastic deformation on the edges of the workpiece creates a burr that is generally undesirable because the function of the product can be impaired. The formation of burrs is minimized by constructional measures, but rarely completely avoidable. Deburring is a surface treatment method that removes the burrs created in the previous machining process.
Die zu entgratenden Werkstücke haben überwiegend planparallele ebene Flächen und weisen an diesen Flächen den Grat auf, der durch den Bearbeitungsprozess der Vorrichtung effizient entfernt und die betroffenen Kanten verrundet werden.The workpieces to be deburred have predominantly plane-parallel planar surfaces and have at these surfaces the ridge, which is efficiently removed by the machining process of the device and the affected edges are rounded.
Für ebene Flächen würde in diesem Fall gewöhnlich das Planbürsten zum Einsatz kommen. Bestehende Planbürstverfahren in der industriellen Fertigung erfolgen im Durchlaufverfahren. Die zu bürstenden Teile werden magnetisch oder mechanisch auf ein Band oder einen Drehtisch fixiert und durchlaufen den Bürstprozess. Dabei werden die Teile zunächst von einer Seite bearbeitet. Anschließend werden sie entweder manuell oder mit einer Automatik gewendet, so dass die andere Seite bearbeitet werden kann.For flat surfaces in this case usually the plan brushing would be used. Existing plan brushing processes in industrial production are carried out in a continuous process. The parts to be brushed are magnetically or mechanically fixed on a belt or turntable and go through the brushing process. The parts are first processed from one side. Then they are turned either manually or with an automatic, so that the other side can be edited.
Nachteile dieses einseitigen Bürstverfahrens sind ein hoher und teurer Maschinen- und Personalaufwand, lange Maschinenlaufzeiten sowie die Fehlermöglichkeit einseitig gebürsteter Teile.Disadvantages of this one-sided brushing method are a high and expensive machine and personnel costs, long machine running times and the possibility of failure of one-sided brushed parts.
Ziel der Erfindung ist die Reduzierung der Durchlaufzeiten des Bürstentgratens, indem gleichzeitig die Ober- und Unterseite der Werkstücke bearbeitet werden. Das Verfahren des parallelen und beidseitigen Entgratens von Werkstücken funktioniert analog dem Planschleifen mit Planetenantrieb.The aim of the invention is to reduce the throughput times of the Bürstentgratens by the same time the top and bottom of the workpieces are processed. The process of parallel and two-sided deburring of workpieces works analogously to surface grinding with planetary drive.
Die Erfindung beschreibt eine Vorrichtung zum gleichzeitigen Entgraten und/oder Oberflächenbearbeiten der Ober- und Unterseite von Werkstücken, wobei die Werkstücke zwischen zwei horizontal übereinander gelagerten Bürstscheiben in außenverzahnten Werkstückhalter positioniert werden. Zunächst werden die Werkstücke manuell in den Eingriffen der Werkstückhalter auf der unteren Bürstscheibe fixiert, so dass sie lose in den Eingriffen haltbar sind. Anschließend wird die obere Bürstscheibe auf einen verstellbaren Festanschlag oder über ein Messsystem auf die Werkstücke heruntergefahren, so dass sich die Vorrichtung schließt. Die Werkstückhalter, die zwischen einem inneren und einem äußeren Stiftkranz platziert sind, werden durch einen Planetenantrieb im Bereich des inneren Stiftkranzes in Relativbewegung zu den ebenfalls rotierenden Bürsten versetzt, wodurch sie sich drehen. Hierbei werden im Rotationsverfahren, bei dem beide Bürstscheiben gleichzeitig im Eingriff sind, alle sich in den Werkstückhaltern befindenden Werkstücke zwischen den beiden Bürstscheiben sowohl auf der Ober- als auch der Unterseite des Werkstückes entgratet und/oder oberflächenberarbeitet. Während sich die Werkstücke in den Eingriffen der Werkstückhalter befinden, rotieren diese bei Bewegung der Werkstückhalter durch den Planetenantrieb mit.The invention relates to a device for simultaneous deburring and / or surface machining of the top and bottom of workpieces, wherein the workpieces are positioned between two horizontal superimposed brush discs in externally toothed workpiece holder. First, the workpieces are manually fixed in the interventions of the workpiece holder on the lower brush disk, so that they loose in the Interventions are durable. Subsequently, the upper brush disk is shut down to an adjustable fixed stop or a measuring system on the workpieces, so that the device closes. The workpiece holders, which are placed between an inner and an outer pin collar, are offset by a planetary drive in the region of the inner pin ring in relative movement to the likewise rotating brushes, whereby they rotate. In the process of rotation, in which both brushing disks are simultaneously in engagement, all workpieces located in the workpiece holders are deburred and / or surface-finished between the two brushing disks on both the upper and the lower side of the workpiece. While the workpieces are in the interventions of the workpiece holder, they rotate with the movement of the workpiece holder by the planetary drive with.
Auf der unteren Bürstscheibe liegt zwischen innerem und äußerem Stiftkranz eine Mindestanzahl von drei Werkstückhaltern auf. Die Anzahl der Werkstückhalter ist von der Größe der Stiftkränze und der Entfernung des inneren und äußeren Stiftkranzes zueinander abhängig. Je nach Durchmesser der Stiftkränze lässt sich eine höhere Anzahl an Werkstückhaltern zwischen die beiden Kränze einfügen.There is a minimum number of three workpiece holders on the lower brush disk between the inner and outer pin rings. The number of workpiece holders depends on the size of the pin rings and the distance of the inner and outer pin ring each other. Depending on the diameter of the pin rings, a higher number of workpiece holders can be inserted between the two rings.
Die Eingriffe in den Werkstückhaltern für die Fixierung der Werkstücke können individuell gestaltet werden. Der Durchmesser des Eingriffs ist vom Durchmesser des zu bearbeitenden Werkstückes, die Tiefe des Eingriffes ist von der Höhe des Werkstückes abhängig.The interventions in the workpiece holders for the fixation of the workpieces can be designed individually. The diameter of the engagement is the diameter of the workpiece to be machined, the depth of the engagement depends on the height of the workpiece.
Jede der beiden Bürstscheiben besteht aus einer Trägerscheibe aus Metall sowie einer darunter bzw. darüber montierten Bürstenaufnahme aus Pertinax, Kunststoff oder Aluminium, die vollflächig mit Bürsten bestückt wird.Each of the two brush discs consists of a metal carrier disc and a Pertinax, plastic or aluminum brush holder mounted underneath or above, which is equipped with brushes over its entire surface.
Die obere und untere Bürstscheibe sowie der Planetenantrieb können sowohl in Drehrichtung als auch in Drehgeschwindigkeit jeweils variieren. Sie lassen sich entweder im Uhrzeigersinn oder gegen den Uhrzeigersinn drehen. Die Drehgeschwindigkeit kann bei allen frei festgelegt und zur Optimierung des Entgratens angepasst werden.The upper and lower brush disk and the planetary drive can vary both in the direction of rotation and in rotational speed. They can be rotated either clockwise or counterclockwise. The rotation speed can be freely set for all and adapted to optimize the deburring.
Hierbei ist es zum Beispiel möglich die obere und untere Bürstscheibe bei jeweils verschiedenen Drehgeschwindigkeiten in unterschiedliche Richtungen laufen und wiederum den Planetenantrieb die Werkstückhalter bei einer dritten Geschwindigkeit antreiben zu lassen.In this case, it is possible, for example, for the upper and lower brush disks to run in different directions at different rotational speeds and, in turn, for the planetary drive to drive the workpiece holders at a third speed.
Die Eindringtiefe der Bürsten, also die Wegstrecke, die die obere Bürste vertikal in Richtung Werkstück gesenkt wird, so dass die Bürsten die Oberseite des Werkstücks berühren, ist durch das Absenken der oberen Bürstscheibe auf einen verstellbaren Festanschlag oder durch ein Messsystem einstellbar und kann hierdurch der jeweiligen Höhe des Werkstückes angepasst werden.The depth of penetration of the brushes, so the distance that the upper brush is lowered vertically towards the workpiece so that the brushes touch the top of the workpiece, is by lowering the upper brush disc on an adjustable fixed stop or by a Adjustable measuring system and can thereby be adapted to the respective height of the workpiece.
Die Bearbeitung der Werkstücke in der Vorrichtung wird gesteuert über die Einstellparameter Eindringtiefe der Bürsten auf die Ober- und Unterseite der Werkstücke, die Laufzeit der Bearbeitung und die Drehzahl der Rotation der Bürsten. Die Kombination der Einstellparameter erfolgt nach der individuellen Auslegung und Einstellung der Werkstücke und ermöglicht ein gezieltes Entgraten und Kantenverrunden der zu bearbeitenden Werkstücke.The processing of the workpieces in the device is controlled by the adjustment parameters penetration depth of the brushes on the top and bottom of the workpieces, the duration of processing and the speed of rotation of the brushes. The combination of the setting parameters is based on the individual design and setting of the workpieces and enables targeted deburring and edge rounding of the workpieces to be machined.
Die
Die Erfindung unterscheidet sich von der soeben genannten
Die Erfindung beschreibt jedoch eine Vorrichtung, bei der die Werkstücke in die Werkstückhalter auf die untere Bürstscheibe aufgelegt werden, sich die Vorrichtung anschließend schließt, indem die obere Bürstscheibe herunterfährt und dann die Werkstücke durch die Rotation sowohl der unteren als auch der oberen Bürstscheibe als auch den Werkstückhaltern auf Ober- und Unterseite entgratet und/oder oberflächenbearbeitet werden. Nach dem Bearbeitungsprozess fährt die obere Bürstscheibe nach oben und die fertig entgrateten und/oder oberflächenbearbeiteten Werkstücke können der Vorrichtung entnommen werden.However, the invention describes a device in which the workpieces are placed in the workpiece holder on the lower brushing disk, the device then closes by the upper Bürstscheibe herunterfährt and then the workpieces by the rotation of both the lower and the upper brush disk and the Workpiece holders on top and bottom are deburred and / or surface-treated. After the machining process, the upper brush disk moves upwards and the finished deburred and / or surface machined workpieces can be removed from the device.
