Description
Rundschleifkopf zu Schleifmaschinen. Vorliegende Erfindung hat den Zweck, einen zur Schleifmaschine nach dem Patent 377o87 passenden Rundschleifkopf zu schaffen, um eine einfache, leichte und kleine, aber widerstandsfähige Maschine zum Ausschleifeil zylindrischer und konischer Ausnehmungell und speziell kleiner, kleinster, aber auch größerer Bohrungen zu erzielen, wobei die verschiedenen Arbeitsgänge leicht durch entsprechende Lehren und Kaliber während dieser Arbeitsgänge kontrolliert werden könliell.Round grinding head for grinding machines. The present invention has the Purpose, a cylindrical grinding head that fits the grinding machine according to patent 377o87 to create a simple, light and small but robust machine Cylindrical and conical recesses for the grinding file and especially smaller, to achieve the smallest, but also larger bores, with the various operations easily controlled by appropriate gauges and calibers during these operations become royal.
Zu diesem Zweck besteht der Rundschleifkopf aus einem dreh- und verstellbaren Schleiftisch und einer vertikalen Schleifspindel, die durch den Schleiftisch hindurchragt. Der die Lagerung des oberen Schleifspindelendes aufnehmende, in einem verstellbaren Arm gelagerte Teil ist als eine mit seitlicher Stangenverzahnung o. dgl. versehene rohr-Krmige Büchse ausgebildet sowie im Arm mittels Zahnradgetriebes vertikal verstellbar sowie den entsprechend verlängerten oberen Schleifspindelteil in Kugellagern leicht drehbar, aber achsial unverschiebbar aufnimmt, während der das Werkzeug unten aufnehniende und tragende Schleifspindelteil unverdrehbar, aber auf Feder und Nut verschiebbar in der Bohrung der die schleifspindelantreibenden Welle sitzt, zum Zweck, die Schleifspindel aclisial verschieben zu können.For this purpose, the cylindrical grinding head consists of a rotatable and adjustable one Grinding table and a vertical grinding spindle that protrudes through the grinding table. The one accommodating the bearing of the upper end of the grinding spindle, in an adjustable one The arm-mounted part is provided with a lateral bar toothing or the like tubular sleeve designed and vertically adjustable in the arm by means of a gear drive as well as the correspondingly lengthened upper grinding spindle part in ball bearings rotatable, but axially immovable, while the tool below takes up and bearing part of the grinding spindle cannot be rotated, but can be moved on a tongue and groove The grinding spindle is seated in the bore of the shaft that drives the grinding spindle aclisial to move.
Die Zeichnung stellt eine Ansicht des Schleifkopfes im Schnitt dar.The drawing shows a view of the grinding head in section.
Die vertikal angetriebene Schleifspindel S besitzt in ihrem oberen Ende eine zvlindrische Bohrung mit seitlichem Federkeil A, in welche der genutete untere Fortsatz des Dorlies D, der das Schleifmittel trägt, vertikal verschiebbar eingesetzt ist. Andererseits besitzt der Schleifdorn D einen Konus q., der genau in das untere Ende der vertikal beweglichen Gegenspindel B paßt und in dieser durch einen bajonettartigen Verschluß 5 eingespannt und festgehalten wird.The vertically driven grinding spindle S has in its upper End of a cylindrical bore with a lateral spring wedge A into which the grooved lower extension of the Dorlies D, which carries the abrasive, vertically displaceable is used. On the other hand, the grinding mandrel D has a cone q. Which exactly fits into the lower end of the vertically movable counter spindle B and in this through a bayonet-like closure 5 is clamped and held.
Die bewegliche Gegenspindel B ist in einem rohrartigen Gehäuse R derart gelagert, daß sie sehr leicht drehbar, aber achsial nicht verschiebbar ist. In der vorliegenden beispielweisen Ausführung ist die Gegenspindel in zwei Kugellagern K1 und KZ gelagert, und zwar so, daß der bewegliche Ring des Kugellagers KI einerseits auf der Spindel B durch einen Bund, anderseits durch das fix mit ihr verbundene Widerlager 6 festgehalten wird, während der festsitzende Ring des Kugellagers K1 durch den Lagerdeckel 7 geklemmt ist.The movable counter spindle B is in a tubular housing R such stored so that it can be rotated very easily, but not axially displaced. In the In the present exemplary embodiment, the counter spindle is in two ball bearings K1 and KZ stored in such a way that the movable ring of the ball bearing KI on the one hand on the spindle B by a collar, on the other hand by the one fixed to it Abutment 6 is held, while the tight ring of the ball bearing K1 is clamped by the bearing cover 7.
Das rohrartige Lagergehäuse R ist an einer Seite mit einer Zahnstange Z versehen, die in ein Zahnrad z eingreift, durch welches das Rohr R mit der Gegenspindel B entweder von Hand aus oder automatisch in Abhängigkeit von dein Schleiftisch T oder der Spindel S gehoben und gesenkt werden kann. Das Lagerrohr R wird von einem Arm M gehalten, an dein auch das Triebrad z gelagert ist. Der Arm 11 ist auf der vertikalen Führungssäule F auf und ab verschiebbar und wird durch ein Klemmorgan O zwecks rascher Zentrierung an dem prismatischen Längskeil p festgehalten.The tubular bearing housing R is on one side with a rack Z provided, which engages a gear z, through which the tube R with the counter spindle B either manually or automatically depending on your grinding table T or the spindle S can be raised and lowered. The storage tube R is from a Arm M held, on which the drive wheel z is also supported. The arm 11 is on the vertical guide column F slidable up and down and is by a clamping member O held on the prismatic longitudinal wedge p for the purpose of rapid centering.
