Abstract

The device is used for turning balls (e.g., for playing skittles) made of wood or plastics, and for returning existing balls. It uses a conventional lathe and has two steel holders (13, 14) which can be adjusted on a guide bar with a threaded spindle. This enables a ball to be made in one operation without the need for re-chucking. USE/ADVANTAGE - The wooden ball turning device can be operated even by unskilled staff, and produces accurate work.

Description

Die Erfindung betrifft eine Vorrichtung zum Drehen und Nachdrehen von Kugeln auf einer Holzdrehbank.The invention relates to a device for turning and re-turning of bullets on a wooden lathe.

In der Regel werden Kugeln (Kegelkugeln) oder dergleichen mit der Hand nachgedreht, wobei dies sehr zeitaufwendig ist, da die Kugeln mindestens 10-15 mal umgespannt werden müssen bis eine bestimmte Genauigkeit erreicht wird und diese Arbeit nur von einem qualifi­ zierten Fachmann ausgeführt werden kann oder mit Hilfe einer Schab­ lone gefertigt wird (kopiert). Dazu brauchen sie für jeden Durchmes­ ser eine Schablone, die dann auf das genauste eingerichtet werden muß und sehr zeitaufwendig ist.Usually balls (cone balls) or the like with the Hand turned, although this is very time consuming as the balls must be changed at least 10-15 times until a certain one Accuracy is achieved and this work only by a qualifi graced specialist can be performed or with the help of a scraper lone is manufactured (copied). For this they need for every diameter This is a template that can then be set up precisely must and is very time consuming.

Aufgabe der Erfindung ist es daher, eine Vorrichtung anzuschaffen, die auch von ungelerntem Personal bedienbar ist und dabei präzis arbeitet. The object of the invention is therefore to provide a device which can also be operated by unskilled personnel and is precise is working.  

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß 2 Stahl­ halter gegenüber stehen, die sich auf einer Führungsschiene mit einer Gewindespindel gleichmäßig verstellen lassen. Die Führungs­ schiene sitzt wiederum auf einem Schneckengetriebe mit Grundplatte, die auf der Drehbank befestigt wird, so daß die 2 Stähle in kreisför­ miger Richtung angetrieben werden.According to the invention, this object is achieved in that 2 steel stand opposite, which are on a guide rail of a threaded spindle evenly adjusted. The leadership rail in turn sits on a worm gear with base plate, which is attached to the lathe, so that the 2 steels in circular miger direction are driven.

Somit wird erreicht, daß jeder Stahl nur 1/4 der Kugel bearbeitet und sich durch die Drehung des Werkstückes eine Hälfte ergibt.This means that each steel only processes 1/4 of the ball and one half results from the rotation of the workpiece.

Der 2. Stahl hat die gleiche Funktion. Durch die Feineinstellung (Pos. 8) läßt sich dieser Stahl noch genau justieren, ein präzises Abdrehen der 2. Hälfte erfolgt. Bei Zustellung (Drehung) der Spindel (Pos. 9) kann der Durchmesser von 50 mm bis ca. 240 mm stufenlos reguliert werden.The 2nd steel has the same function. The fine adjustment (item 8 ) allows this steel to be precisely adjusted, and the 2nd half is turned off precisely. The diameter (50 mm to approx. 240 mm) can be infinitely adjusted when the spindle is fed (rotation) (item 9 ).

Eine Kugel kann somit in einem Arbeitsgang gefertigt werden. Ein Umspannen entfällt, da durch die beiden Stähle ganz bis zur Mittel­ achse gefahren werden kann (Pos. 22). Hinterer Stahl bis Vierzack­ spitze und vorderer Stahl bis Körnerspitze. Oder wie Pos. 21 anzeigt mit den 2 Schalen, die auf Vierzack und Körnerspitze gesteckt werden und dann die beiden restlichen Zapfen wegdreht.A ball can thus be manufactured in one operation. There is no need for reclamping because the two steels can travel all the way to the central axis (item 22 ). Rear steel to four-pointed and front steel to center point. Or as pos. 21 indicates with the 2 bowls, which are put on the four-prong and the center punch and then turn the two remaining pins away.
