Description

Die Erfindung betrifft eine Prägepoliervorrichtung für zylindrische Bohrungen mit in radialer Richtung in einem Gehäuse frei beweglich geführten Kugeln, die auf einem im Innern des Gehäuses axial verstellbaren Konus laufen.The invention relates to a burnishing device for cylindrical Bores with balls guided freely movable in the radial direction in a housing, which run on an axially adjustable cone inside the housing.

Durch Konus-Verschiebung wird der Arbeitsdurchmesser der Vorrichtung eingestellt, und zwar etwas größer als die Weite der zu bearbeitenden Bohrung. Die. durch dieses Übermaß erzwungene Aufweitung ist keine bleibende. Infolge der Elastizität der Werkstoffe verengt sich die Bohrung wieder nach Hindurchtritt der Kugeln. Beim Rücklauf der Vorrichtung oder des Werkstückes wird daher eine Lockerung des Einspannschaftes kaum zu vermeiden sein. Erfindungsgemäß wird daher ein in axialer Richtung federnd angeordnetes Unterteil vorgesehen, das die Kugeln gegen die radiale Führungsfläche des Gehäuses drückt. Durch diese Maßnahme wird erreicht, daß beim Zurückziehen des Gerätes die Kugeln selbsttätig ausweichen können, so daß auch der Rücklauf des Gerätes keinerlei Lockerungen des Einspannschaftes zufolge hat. Außerdem sind Kugeln und Laufbahnen von außen her leicht zu übersehen und bequem zu reinigen. Ohne Werkzeug können die Kugeln ausgewechselt wenden. Der große Raum ermöglicht die Unterbringung einer Vielzahl von Kugeln dicht' an dicht liegend.The working diameter of the device is determined by shifting the cone set, slightly larger than the width of the hole to be machined. The. The expansion forced by this excess is not permanent. As a result of elasticity of the materials, the bore narrows again after the balls have passed through. At the Return of the device or the workpiece is therefore a loosening of the clamping shank can hardly be avoided. According to the invention is therefore resilient in the axial direction arranged lower part is provided, which the balls against the radial guide surface the housing presses. This measure ensures that when you withdraw the Device can evade the balls automatically, so that the return of the device does not result in any loosening of the clamping shaft. Also, bullets are and Running tracks can easily be overlooked from the outside and are easy to clean. Without tools can turn the balls changed. The large space allows the accommodation a multitude of balls lying close together.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. In dem mit Einspannschaft 1 versehenen Gehäuse 2 ist mittels Schraube 3 die Achse 4 befestigt. Sie trägt auf ihrem Federteller 10 die Druckfeder 13 und den auf der genannten Achse beweglichen angehängten Unterteil 9; die Kugeln 8 sind eingeklemmt zwischen Gehäuse?" dem Unterteil 9 und der Kegelmantelfläche des zur Achse passend durchbohrten Dornes 7, dessen Gewindeschaft 12 durch Stellmutter 6 und Gegenmutter 5 in bestimmter Höhenlage gehalten wird. In bekannter Weise sind in der Gehäusewandung Durchbrüche vorhanden, um die Stellmutter und Gegenmutter betätigen zu können. Der Verstellbereich ergibt sich aus dem freien Gewindeteil II. Schnitt A-B ist durch die Kugelmitten des Kugelkranzes gelegt. Für den Gebrauch der Vorrichtung ist der Konus 7 starr gelagert, wohingegen Teil 9 beweglich angeordnet ist und unter Federdruck stehend die Kugeln gegen die radiale Führungsfläche des Gehäuses 2 drückt.An exemplary embodiment is shown in the drawing. In the with The housing 2 provided with the clamping shaft 1 is fastened to the axis 4 by means of a screw 3. It carries the compression spring 13 on its spring plate 10 and the one on said axis movable attached lower part 9; the balls 8 are wedged between the housing? " the lower part 9 and the conical surface of the mandrel drilled through to match the axis 7, the threaded shaft 12 of which by adjusting nut 6 and counter nut 5 at a certain height is held. In a known way, there are openings in the housing wall, to be able to operate the adjusting nut and lock nut. The adjustment range results from the free thread part II. Section A-B is through the ball centers of the ball ring placed. For the use of the device, the cone 7 is rigidly mounted, whereas Part 9 is movably arranged and standing under spring pressure, the balls against the radial guide surface of the housing 2 presses.
