Description
Verfahren zum Polieren von sieh drehenden Werkstücken. Gegenstand der Erfindung bildet ein Ver fahren zum Polieren von sich drehenden Werk stücken.
Die Zeichnung stellt ein Ausführungs beispiel einer Vorrichtung zur Durchführung des Verfahrens dar, und zwar zeigt Fig. 1 eine Seitenansicht mit Arbeitsstück, Fig. 2 eine Hinteransicht und Fig. 3 eine Draufsicht des Beispiels. Die Vorrichtung weist eine horizontal, in zwei Ringschmierlagern gela gerte Welle .F' auf, welche quer zur zu polierenden Walze G liegt und durch einen Riemen mit der aufgekeilten Riemenscheibe 9. in Drehbewegung versetzt wird. Auf der Vor derseite ist die topfförmige Polierscheibe B befestigt. Die Welle F mit der Polierscheibe ist nicht nur um ihre eigene Achse, sondern auch in der Längsrichtung beweglich.
Hinten ist ein Flansch C mit einer Feder H und zwei Schrauben angebracht, um den Druck aufzunehmen, der durch Andrücken der Polier scheibe B an die Walze G sich ergibt. Da durch, dass die Welle F in ihrer Längsrich tung federnd ist, passt sich die Polierscheibe B jeder Form an, ob die sich drehende Walze nun zylindrisch, hohl oder bombiert geschlif fen sei. Um bei dem steten Druck der Feder nach vorn. zu verhüten, dass sich die Feder mit der Welle dreht und sich in das hintere Lager hinein arbeitet, sind drei gehärtete Scheiben 0 über die Welle zwischen Lager und Feder gesetzt.
Die eine Scheibe ist am Lager befestigt und nicht drehbar, die mittlere Scheibe ist auf der Welle F fest aufgezogen, die äusserste Scheibe ist lose und wird ledig lich von der Feder an die andern Scheiben angedrückt. Bei Druck von vorn schiebt sich nun die Welle entgegen der Federwirkung nach hinten. Die beiden äussern Scheiben heben sich ,zwangsläufig auch vom Lager weg, weil die mittlere Scheibe auf der Welle fest aufgezogen ist. Die rotierende Bewegung der Welle wirkt sich nicht auf die Feder aus, die Reibung erfolgt zwischen den beiden äussern Scheiben. Unten am Support sind Schraubenlöcher B gebohrt, deren Abmessun gen sich jeweils der Maschine anpassen müs sen, wo die Vorrichtung montiert wird. Es ist jedoch wichtig, dass die untere Randmitte der Polierscheibe genau auf die Spitzenhöhe der Maschine zu liegen kommt.
Von Vorteil ist es, wenn die Welle F nicht genau recht winklig zum polierenden Stück, sondern zirka ein Grad schräg gestellt wird, dadurch arbeitet die Polierscheibe viel besser. Die Vorrich tung benötigt wie beim Schleifen auch Kühl wasser. Die Drehachse des Werkzeuges B steht also quer zur Drehase des Werk stückes G.
Process for polishing rotating workpieces. The invention forms a Ver drive for polishing rotating work pieces.
The drawing shows an embodiment example of a device for carrying out the method, namely FIG. 1 shows a side view with the work piece, FIG. 2 shows a rear view and FIG. 3 shows a top view of the example. The device has a horizontal shaft .F 'mounted in two ring lubrication bearings, which lies transversely to the roller G to be polished and is set in rotary motion by a belt with the wedged pulley 9. On the front side, the cup-shaped polishing wheel B is attached. The shaft F with the polishing wheel is movable not only about its own axis but also in the longitudinal direction.
At the rear, a flange C with a spring H and two screws is attached to absorb the pressure that results from pressing the polishing disk B against the roller G. Because the shaft F is resilient in its longitudinal direction, the polishing wheel B adapts to any shape, whether the rotating roller is cylindrical, hollow or cambered. To with the constant pressure of the spring forward. To prevent the spring from rotating with the shaft and working into the rear bearing, three hardened washers 0 are placed over the shaft between the bearing and the spring.
One disc is attached to the bearing and cannot rotate, the middle disc is tightly mounted on the shaft F, the outermost disc is loose and is only pressed against the other discs by the spring. When pressure is applied from the front, the shaft pushes backwards against the spring action. The two outer disks lift, inevitably away from the bearing, because the middle disk is firmly attached to the shaft. The rotating movement of the shaft does not affect the spring, the friction takes place between the two outer discs. Screw holes B are drilled at the bottom of the support, the dimensions of which must be adapted to the machine where the device is to be mounted. However, it is important that the center of the lower edge of the polishing pad is exactly at the height of the point on the machine.
It is advantageous if the shaft F is not exactly at right angles to the piece to be polished, but rather at an angle of about one degree, so that the polishing wheel works much better. As with grinding, the device also requires cooling water. The axis of rotation of the tool B is thus transverse to the rotary nose of the workpiece G.
