Description
Es sind Vorrichtungen zur Halterung stangenförmiger Werkstoffe bekannt, bestehend aus einem um seine Längsachse drehbaren, seitlich des um eine feste Achse umlaufenden Schnedwerkzeuges angeordneten Rundkörper mit diametral zu beiden Seiten der parallel zur Drehachse des Schneidwerkzeuges verlaufenden Längsachse liegenden Aufnahmebohrungen für die Werkstücke, in welchen die Werkstücke gegen die der Längsachse des Rundkörpers zugekehrte Wandung- anpreßbar sind.There are known devices for holding rod-shaped materials, consisting of a rotatable around its longitudinal axis, laterally around a fixed axis rotating cutting tool arranged round body with diametrically on both sides the longitudinal axis running parallel to the axis of rotation of the cutting tool Mounting holes for the workpieces, in which the workpieces against the longitudinal axis the wall facing the round body can be pressed against.
Bei diesen bekannten Einrichtungen ist.-eine Vielzahl von Aufnahmebohrungen vorhanden, die auf einem Teilkreis verhältnismäßig großen Durchmessers angeordnet sind.These known devices have a large number of mounting bores present, which are arranged on a pitch circle of relatively large diameter are.
Die Erfindung betrifft eine Vorrichtung zur Halterung stangenförmiger Werkstücke für Kreissäge- und Trennschleifmaschinen, bei denen das Werkstück zur Erzielung einer keilförmigen Spanform um den Anschnittpunkt drehbar sein muß. Für diesen besonderen Zweck wird die bekannte Vorrichtung zur Halterung stangenförmiger Werkstücke erfindungsgemäß in der Weise ausgebildet, daß zwei Aufnahmebohrungen vorhanden sind, die möglichst nahe an die Längsachse des Rundkörpers herangerückt sind, wobei die Längsachse des Rundkörpers zweckmäßig in bekannter Weise quer zur Drehachse des Werkzeuges verschiebbar eingerichtet ist.The invention relates to a device for holding rod-shaped Workpieces for circular saws and cut-off machines where the workpiece is used Achieving a wedge-shaped chip shape must be rotatable around the cutting point. For For this particular purpose, the known device for holding is rod-shaped Workpieces according to the invention designed in such a way that two receiving bores are present that moved as close as possible to the longitudinal axis of the round body are, the longitudinal axis of the round body expediently in a known manner transversely to The axis of rotation of the tool is set up to be displaceable.
Es sei -bemerkt, däß bei einer Ausbildung der Vorrichtung mit einer -Vielzahl von Aufnahmebohrungen auf einem Teilkreis großen Durchmessers die Erzielung einer keilförmigen Spanform nicht möglich ist. Erst durch die erfindungsgemäße Ausbildung der Vorrichtung ist diese keilförmige. Spanform gewährleistet.It should be noted that when the device is designed with a -Multiple of mounting holes on a pitch circle of large diameter the achievement a wedge-shaped chip form is not possible. Only through the training according to the invention the device is wedge-shaped. Chip shape guaranteed.
Zur Erläuterung der Erfindung ist in der Zeichnung ein Ausführungsbeispiel im Schnitt schematisch dargestellt. g ist ein Kreissägeblatt, welches in Richtung des Pfeiles f umläuft. Der Werkstückhalter ist ein um seine Längsachse drehbarer Rundkörper a, welcher seitlich des Sägeblattes gelagert ist. Die Längsachse d, welche parallel zur Drehachse des Sägeblattes g angeordnet ist, ist quer zur Drehachse d des Rundkörpers a verschieblich, so däß der Werkstückhalter dem Durchmesser des verwendeten Kreissägeblattes g - entsprechend eingestellt werden kann, und zwar möglichst so, daß die Längsachse d den Umfang des Kreissägeblattes trifft. Der Rundkörper a wird in Richtung des Pfeiles e gedreht, wenn das Werkstück lt ibearbeitet werden soll. Der Rundkörper a hat zweiAufnahmebohrungen f, die möglichst nahe an die Längsachse herangerückt sind. In diese Aufnahmebohrungen werden die stangenförmigen Werkstücke eingeschoben und durch Spannschrauben, die durch die Pfeile c angedeutet sind, gegen die nach der Längsachse hin liegenden Wandungsteile der Bohrungen b angedrückt. Die Spannschrauben c sind symmetrisch zu dem durch die Bohrungsmittelpunkte bestimmten Durchmesser des Rundkörpers a zu diesem Durchmesser geneigt angeordnet.To explain the invention, an exemplary embodiment is shown schematically in section in the drawing. g is a circular saw blade that rotates in the direction of arrow f. The workpiece holder is a round body a which can be rotated about its longitudinal axis and is mounted to the side of the saw blade. The longitudinal axis d, which is arranged parallel to the axis of rotation of the saw blade g, is displaceable transversely to the axis of rotation d of the round body a, so that the workpiece holder can be adjusted according to the diameter of the circular saw blade g used, preferably so that the longitudinal axis d denotes Circumference of the circular saw blade meets. The round body a is rotated in the direction of arrow e when the workpiece is to be machined. The round body a has two mounting holes f, which are moved as close as possible to the longitudinal axis. The rod-shaped workpieces are pushed into these receiving bores and are pressed against the wall parts of the bores b, which are located towards the longitudinal axis, by clamping screws, which are indicated by the arrows c. The tensioning screws c are arranged symmetrically to the diameter of the round body a determined by the center of the hole and inclined to this diameter.
