 <Desc/Clms Page number 2> 

 eine   Messvorrichtung   19 tragenden   Schiene 20   dient. Mit Hilfe einer am Gehäuse 18 befestigten Mikrometerschraube 21 kann der Fühler 9 durch Heben und Senken des Armes.   14,   der auf die Stange 15 wirkt, radial verstellt werden. Der Arm. 34 ist mit dem Gehäuse 18 verbunden. Dieses wird durch die Mikrometerschraube 21 an einer (nicht dargestellten) Führung dadurch in lotrechter Richtung verschoben, dass der Kopf der Schraube 21 sich gegen eine fest mit dem Maschinengestell verbundene Anschlagleiste 21 a legt. Die Verstellung der Stange 15 kann aber auch auf andere Weise bewirkt werden.

   Die   Messvorrichtung   19 wird bei Benutzung der Zentriervorrichtung in der aus Fig. 1 ersieht- 
 EMI2.1 
   Werkstückes   entfernt. Zum Zentrieren wird das Bohrungsmitte gegenüber dem Spindelmittel so lange verschoben, bis ein allseitig gleichmässiges Aufleuchten oder Dunkelbleiben der Lampen 17 beim Umlauf des Fühlers 9 auf dem ganzen Umfang erreicht ist. 



   PATENT-ANSPRÜCHE :
1. Zentriervorriehtung für Bohrmaschinen, insbesondere solche für Feinbearbeitung, dadurch gekennzeichnet, dass die Bohrspindel   (1)   am unteren Ende mit einem in radialer Richtung fest einstellbaren Fühler   (9)   versehen ist, der mit mehreren im Kreise angeordneten Glühlampen   (17)   über eine in der Bohrspindelmitte angeordnete Stange   (15)   und eine Verteilerkontaktwalze (16 a) elektrisch leitend verbunden ist, so dass beim Umlauf des Fühlers   (9)   die Glühlampen entsprechend der Exzentrizität der Bohrung aufleuchten.

    Centering device for drilling machines, in particular those for fine machining.
 EMI1.1
 

 <Desc / Clms Page number 2>

 a measuring device 19 carrying rail 20 is used. With the aid of a micrometer screw 21 attached to the housing 18, the feeler 9 can be moved by raising and lowering the arm. 14, which acts on the rod 15, can be adjusted radially. The arm. 34 is connected to the housing 18. This is displaced in the vertical direction by the micrometer screw 21 on a guide (not shown) in that the head of the screw 21 rests against a stop bar 21 a firmly connected to the machine frame. The adjustment of the rod 15 can also be effected in other ways.

   The measuring device 19 is seen when using the centering device in the FIG.
 EMI2.1
   Workpiece removed. For centering, the center of the hole is displaced relative to the spindle means until the lamps 17 light up uniformly on all sides or remain dark over the entire circumference as the sensor 9 rotates.



   PATENT CLAIMS:
1. Centering device for drilling machines, especially those for fine machining, characterized in that the drilling spindle (1) is provided at the lower end with a radially adjustable sensor (9), which is equipped with several incandescent lamps (17) arranged in a circle via an in the rod (15) arranged in the middle of the drilling spindle and a distributor contact roller (16 a) is connected in an electrically conductive manner, so that when the sensor (9) rotates, the light bulbs light up according to the eccentricity of the bore.

Claims (1)

2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die in der Bohrspindelmitte angeordnete Spange in der Richtung ihrer Achse verschiebbar und mit dem Fühler (9) zum Zwecke seiner radialen Einstellung durch als Keile wirkende Teile einen Hebel usw. verbunden ist. EMI2.2 2. Device according to claim 1, characterized in that the clasp arranged in the center of the drilling spindle is displaceable in the direction of its axis and connected to the sensor (9) for the purpose of its radial adjustment by parts acting as wedges, a lever, etc. EMI2.2
