Abstract

A tool which has spacer sleeves displaceable on a center punch and hollow shafts are adjacent to one another is intended for rapidly and precisely finding the center of holes and the longitudinal center of slots and channels, so that center marks and linear scribes can be made. The spacer sleeves and the hollow shafts have different diameters, and the hollow shafts are inserted one into the other in telescopic form. When a hollow shaft is fittingly inserted into hole (5) or slot (5) the center of the former or the longitudinal center of the latter can reliably be found by the center punch for making center marks or linear scribes in the slots. The tool can also be used for producing center marks on shafts and pins.

Description

Das Anbringen von punkt- oder linienartigen Markierungen in die Oberfläche eines Werkstückes aus Metall, Holz oder Kunststoff wird mittels eines Körnerstiftes aus Hartmetall vorgenommen, Markierung und Körnungen in Löcher oder auf Wellen sowie linienartige Ritzungen für Anreisszwecke in schlitzartigen Vertiefungen lassen sich mit Genauigkeit nur mit grossem Zeitaufwand ausführen und erfordern handwerkliches Geschick, denn es ist schwer rasch und genau das Zentrum von Löchern oder die Längsmitte von Schlitzen und Nuten zu ermitteln, weshalb Fehler häufig sind. Eine abgebrochene Schraube in einem Werkstück herauszunehmen ist ebenfalls umständlich. Die im Werkstück steckende, abgebrochene Schraube ist herauszubohren und es gelingt meistens nur ausnahmsweise das Zentrum für das Ansetzen eines Bohrwerkzeuges zur Vornahme der Ausbohrung genau zu ermitteln. Bei Ungenauigkeit wird das Schraubengewinde im Werkstück beim Herausbohren-der abgebrochenen Schraube beschädigt, die allfällig reparierte Schraubverbindung wird verunsichert und die neue Schraube-passt nicht. Als Ausweg bleibt jeweils nur das Schneiden eines neuen Gewindes im Werkstück und die Verwendung einer passenden Schraube übrig. Ebenfalls schnelles Zentrieren z.B. an einer Schraube erspart das umständliche Einspannen in der Drehmaschine.The punctiform or line-like markings in the surface of a workpiece made of metal, wood or plastic are made using a centering pin made of hard metal, marking and grainings in holes or on shafts as well as line-like scratches for scribing purposes in slot-like depressions can only be done with great accuracy It takes time and requires manual skill, because it is difficult to quickly and precisely determine the center of holes or the longitudinal center of slots and grooves, which is why errors are common. Removing a broken screw in a workpiece is also cumbersome. The broken screw in the workpiece has to be drilled out and it is usually only possible to determine the center for attaching a drilling tool to carry out the drilling. In the event of inaccuracy, the screw thread in the workpiece is damaged when drilling out the broken screw, the possibly repaired screw connection is unsettled and the new screw does not fit. The only way out is to cut a new thread in the workpiece and use a suitable screw. Also quick centering e.g. One screw saves laborious clamping in the lathe.

Gegenstand der Erfindung ist ein Werkzeug zum Körnen und Anreissen von Werkstücken. Derselben.liegt die Aufgabe zugrunde das Zentrum von beliebig gestalteten zylindrischen, konischen sowie abgestuften Löchern oder die Längsmitte in Schlitzen wie auch auf Wellen sicher und rasch zu finden, um in einer Werkstückoberfläche punkt- oder linienartige Markierungen anzubringen. Durch schnelles und leichtes Zentrieren an einer Schraube, einem Zapfen oder einer Welle lässt sich ferner das umständliche Einspannen in einem Drehaggregat ersparen.The invention relates to a tool for graining and marking workpieces. The same is based on the task of finding the center of any cylindrical, conical and stepped holes or the longitudinal center in slots as well as on shafts safely and quickly in order to make point or line-like markings on a workpiece surface. Through quick and easy Centering on a screw, a pin or a shaft can also save the laborious clamping in a turning unit.

1 bezeichnet einen aus Hartmetall bestehenden Körnerstift, welcher einerends mit einer Spitze 2 und anderseits mit einem Schlagkopf 3 versehen ist. Für Normalgebrauch ist eine Länge des Körnerstiftes von ca. 7 cm und eine Dicke von ca. 2-3 mm geeignet. Auf dem Körnerstift 1 ist eine aus mehreren Stücken bestehende Gruppe teleskopartig ineinandergreifenden, verschiebbaren Hohlschäften 4 gelagert. Es können je nach Verwendungsart aber weniger oder mehr als sieben Hohlschäfte gebraucht werden. An den oberen Enden der Hohlschäfte 4 befindet sich je eine Distanzbuchse 5. Die Distanzbuchsen haben zueinander verschiedene Weiten und Durchmesser. Die Hohlschäfte 4 und die Distanzbuchsen 5 bestehen aus je einem Stück, sie können aber auch Einzelteile sein, die durch Verschweissung miteinander verbunden, oder aus einem Stück geformt sind. Die Weiten der Hohlschäfte 4 vergrössern sich von unten nach oben um je ca. 1 mm, diejenigen der Distanzbuchsen 5 dagegen von oben nach unten um ca. 1 mm.1 denotes a grain pin made of hard metal, which is provided on one end with a tip 2 and on the other hand with a striking head 3. For normal use, a length of the center pin of approx. 7 cm and a thickness of approx. 2-3 mm are suitable. On the grain pin 1 is a group consisting of several pieces telescopically interlocking, displaceable hollow shafts 4 is mounted. Depending on the type of use, fewer or more than seven hollow shafts can be used. There is a spacer bushing 5 at each of the upper ends of the hollow shafts 4. The spacer bushings have different widths and diameters from one another. The hollow shafts 4 and the spacers 5 each consist of one piece, but they can also be individual parts which are connected to one another by welding or are formed from one piece. The widths of the hollow shafts 4 increase from bottom to top by approx. 1 mm each, those of the spacer bushes 5, on the other hand, increase from top to bottom by approx. 1 mm.

Nach Fig. 5 und 6 sind an den Umfangsseiten der Distanzbuchsen 5 Arretierschrauben 6 angebracht, deren Köpfe abstehen. Bei Anzug der Arretierschrauben 6 lassen sich die Distanzbuchsen 5 mit den Hohlschäften 4 am Körnerstift 1 festlegen. Nach fig. 6 ist als Zugmittel ein Gummiband 7 über einen Teil der Arretierschrauben 6 gelegt und bezweckt die Distanzbuchsen 5 aneinander zu ziehen und die Hohlschäfte 4 auseinander zu halten, wenn die Arretierschrauben 6 nicht angezogen sind. Das selbständige Wegfallen vom Körnerstift 1 bei den Körnungsarbeiten kann dadurch verhindert und das Werkzeug in..Bereitschaftstellung gehalten werden. In Fig. 6 greift der vierte Hohlschaft 4 passend in das Loch 9, während die restlichen grösseren Hohlschäfte dem Werkstück 8 aufliegen. In Fig. 5 ist das Loch 9 sehr klein, in Fig. 6: dagegen mehrfach grösser. Im untersten Hohlschaft liegen die anderen teleskopartig ineinander geschobenen Hohlschäfte. Der Körnerstift 1 bzw. die Spitze 2 befindet sich genau im Zentrum des Loches 9. Die Distanzbuchse 5 liegen dabei aufeinander. In Fig. 5a umgreift ein Hohlschäft 4 eine Welle 8' und die Spitze des Körnerstiftes 1 liegt der Stirnseite derselben an, wo die Körnung vorgenoznmen wird. Dasselbe ist der Fall wenn sich anstelle der Welle 8' ein Zapfen befindet. Zwei dem Werkstück 8 aufliegende Hohlschäfte 4 dienen dabei als rechtwinklige, stützende Auflage, welche das Verkanten des Werkzeuges erschweren.5 and 6 5 locking screws 6 are attached to the peripheral sides of the spacers, the heads of which protrude. When the locking screws 6 are tightened, the spacers 5 with the hollow shafts 4 on the center pin 1 establish. According to fig. 6, a rubber band 7 is placed over a part of the locking screws 6 as a traction means and is intended to pull the spacer bushes 5 together and to keep the hollow shafts 4 apart when the locking screws 6 are not tightened. This prevents the grain pin 1 from falling away independently during the grain work and the tool can be kept in the ready position. In Fig. 6 the fourth hollow shaft 4 fits into the hole 9, while the remaining larger hollow shafts rest on the workpiece 8. In Fig. 5 the hole 9 is very small, in Fig. 6: on the other hand several times larger. The other hollow shafts are telescoped into the lowest hollow shaft. The center pin 1 or the tip 2 is located exactly in the center of the hole 9. The spacer bush 5 lie on top of each other. In Fig. 5a, a hollow shaft 4 encompasses a shaft 8 'and the tip of the grain pin 1 lies against the end face of the same, where the grain is made. The same is the case if there is a pin instead of the shaft 8 '. Two hollow shanks 4 resting on the workpiece 8 serve as a right-angled, supporting support, which make it difficult to tilt the tool.

Das Werkstück 8 känn auf einem weiteren in Fig. 8, 9 und 11 gezeichneten Werkstück 10 liegen und durch Schläge auf den Körnerstift wer den auf dessen Oberfläche Körnungen erzeugt, welche kegelige Vertiefungen sind.The workpiece 8 may lie on another in Fig. 8, 9 and 11 drawn workpiece 10 and by striking the grain pen who produces the grain on its surface, which are conical depressions.

Mit dem Werkzeug lassen sich in Schiltzen oder Rinnen ebenfalls genau in der Längsmitte derselben liegende An reisslinien ziehen resp ritzen. Der untere Teil des Werkzeuges mit dem Körnerstift 1 mit einem passenden Hohlschaft ist einfach in den Schlitz 9', die Rinne 9" der Welle 81 oder des Zapfens einzuführen., wobei die Spitze 2 selbsttätig, genau die durch strichpunktierte Linien dargestellte längsmittige Stellung einnimmt. Durch Hin- und Herziehen des Werkzeuges entstehen im Schlitz oder in der Rinne jeweis längsmittige Anreisslinien 18. Die sich kreuzenden Stellen der Anreisslinien in den Schlitzen oder Rinnen, wie aus Fig. 10 ersichtlich, zeigen die Kreuzpunkte genau an. In Fig. 10 sind noch vier verschieden grosse Löcher 9 vorhanden, deren Zentren sich mit dem Werkzeug rasch und genau, zwecks Vornahme von Körnungen, ermitteln lassen.With the tool, marking lines can also be drawn or scratched in sections or channels exactly in the longitudinal center of the same. The lower part of the tool with the center pin 1 with a matching hollow shaft is easy to insert into the slot 9 ', the groove 9 "of the shaft 8 1 or the pin. The tip 2 automatically, exactly that shown by dash-dotted lines posed longitudinal center position. By pulling the tool back and forth, longitudinal scribe lines 18 are created in the slot or in the groove. The intersecting points of the scribe lines in the slots or grooves, as can be seen in FIG. 10, show the cross points exactly. In Fig. 10 there are still four holes 9 of different sizes, the centers of which can be determined quickly and precisely with the tool for the purpose of carrying out granulations.

Um eine Gruppe von in gleichen Abständen zueinander liegenden Vertiefungen auf dem Werkstück 8 zu schaffen, dient der in Fig. 11 offenbarte Distanzeinstelller 12. Am Distanzeinsteller sind zwei Querträger 14 beweglich befestigt, die sich mittels den Klemmschrauben 17 fixieren lassen, um so die Distanz des Körnerstiftes 1 genau einstellen und sichern zu können. Steckt man den Fühlerdorn 16 in eine, vorangehend durch den Körnerstift erzeugte Kerbe, so nimmt der Körnerstift 1 eine zu dieser distanzierte Stellung ein. Bei Wiederholung dieses Vorganges, wobei der Fühlerdorn jeweils in die neu erzeugte Kerbe eingeführt wird, lässt sich mittels eines konventionellen Rohrwerkzeuges leicht eine Gruppe von gleichmässige Abstände zueinander aufweisende Vertiefungen 11 herstellen (Fig. 11a).In order to create a group of equally spaced depressions on the workpiece 8, the distance adjuster 12 shown in FIG. 11 is used. Two cross members 14 are movably attached to the distance adjuster, which can be fixed by means of the clamping screws 17, so as to adjust the distance of the To be able to set and secure center pin 1 precisely. If the probe pin 16 is inserted into a notch previously produced by the center pin, the center pin 1 assumes a position distant from this. When this process is repeated, with the sensor mandrel being inserted into the newly created notch, a group of uniformly spaced-apart depressions 11 can easily be produced using a conventional pipe tool (FIG. 11a).

Das beschriebene Werkzeug ist für Handwerker wie Mechaniker, Schlosser, Werkzeugmacher, Schreiner und Bastler besonders geeignet, welche Arbeiten ausführen, bei denen die Zentren von Löchern oder die Längsmitten von Schlitzen und Rinnen, Wellen und Zapfen, als auch die Kreuzpunkte von sich kreuzenden Schlitzen oder Rinnen zu bestimmen sind. Das Herausbohren abgebrochener Schrauben, ohne Beschädigungsgefahr des Gewindes im Werkstück, wird zufolge der Möglichkeit, an der Abbruchstelle der Schraube eine zentrisch genaue Körnung anzubringen, welche als Orientierungshilfe bei der Ansetzung des zur Anwendung kommenden Bohrwerkzeuges wirkt.The tool described is particularly suitable for craftsmen such as mechanics, locksmiths, toolmakers, carpenters and hobbyists who carry out work in which the centers of holes or the longitudinal center of slots and channels, shafts and pins, as well as the cross points of intersecting slots or Channels are to be determined. Drilling out broken screws without risking damage to the thread in the workpiece becomes possible due to the possibility of attaching a centrically accurate grain to the point where the screw breaks off, which acts as an orientation aid when attaching the drilling tool to be used.
