Description
Die Erfindung betrifft die Vorrichtung zum Herstellen genauer auszubuchsender Bohrungen in einstellbarem, genauem Abstand voneinander auf Maschinen mit in waagerechter Richtung verstellbarer Bohrspindel nach Patent 543 726. Das Neue besteht in einer zweckmäßigen Verwendung dieser Vorrichtung zum genauen Ausbohren von Buchsen, die in die zuerst gebolirten Löcher eingepreßt werden. Es wird nach der zusätzlichen Erfindung so vorgegangen, daß in die nach einem Endmaß eingestellten, ausgebohrten und aufgeriebenen Löcher ohne Umspannen des Werkstückes Buchsen eingepreßt werden und anschließend deren Innendurchmesser ohne Veränderung der Bohrungsmittenabstände maßhaltig aufgerieben wird. Es kann so für größte Genauigkeit der fertig ausgebuchsten Bohrungen Gewähr geleistet werden.The invention relates to the device for making holes to be bulged more precisely at an adjustable, precise distance from one another on machines with a horizontally adjustable drilling spindle according to the patent 543 726. The novelty consists in an expedient use of this device for the precise drilling of bushings, which in the holes that are first torched are pressed in. It is made according to the additional invention proceeded in such a way that in the adjusted, drilled and reamed according to a final dimension Holes can be pressed in without reclamping the workpiece and bushings then their inner diameter without changing the hole center distances is rubbed true to size. It can be booked out so for the greatest accuracy of the finished Drilling guarantee.
so An Hand der Zeichnung ist nachstehend die Erfindung erläutert. Es zeigt:The invention is explained below with reference to the drawing. It shows:
Fig. ι einen senkrechten Schnitt durch die beispielsweise verwendete Vorrichtung und Fig. 2 eine Draufsicht dazu.Fig. Ι a vertical section through the device used for example and Fig. 2 is a plan view of this.
«5 Auf den Lagerböcken 2, 3 sind Revolverscheiben 4, 4' drehbar und einstellbar gelagert, die mit ausgebuchsten Löchern verschiedenen Durchmessers zur Führung des Werkzeuges 22 zum Ausbohren bzw. Ausreiben der Löeher 16,17 des Werkstückes 15 versehen sind. Bei dieser Arbeit wird ein Zapfen 22' des Werkzeuges in Führungsbuchsen 23, 24 der Lagerböcke 2, 3 besonders geführt.«5 Turret disks 4, 4 'are rotatably and adjustably mounted on the bearing blocks 2, 3, those with bulged holes of different diameters for guiding the tool 22 for boring out or reaming out the holes 16, 17 of the workpiece 15 are provided. In this work, a pin 22 'of the tool in guide bushes 23, 24 of the Bearing blocks 2, 3 specially guided.
Nachdem die Löcher 16, 17 des Arbeitsstückes 15 ausgerieben sind, werden, ohne das Werkstück auszuspannen, in. die Löcher Buchsen 29 eingepreßt. Das Eintreiben der Buchsen geschieht mit einem Stempel, der durch eine der im Durchmesser größeren Bohrungen der Revolverscheiben oder durch eine Aussparung in derselben eingeführt wird. Anschließend werden die Bohrungen der eingepreßten Buchsen 29, ebenfalls ohne das Werkstück auszuspannen, durch ein passendes, in einer Bohrbuchse der Revolverscheiben und mit einem Zapfen 30' in den Führungsbuchsen 23 bzw. 24 geführtes Werkzeug 30 ohne Veränderung der Bohrungsmittenabstände maßhaltig aufgerieben. Der Abstand der Bohrungsmittenabstände kann statt durch auf die Tischplatte gelegte Endmaße auch durch ein Kugelendmaß 31 eingestellt werden, wodurch die Genauigkeit noch erhöht wird.After the holes 16, 17 of the work piece 15 are rubbed out, without unclamping the workpiece, sockets in the holes 29 pressed in. The bushings are driven in with a punch that passes through one of the larger diameter holes of the turret discs or through a Recess is introduced in the same. Then the holes are pressed in Bushings 29, also without unclamping the workpiece, by a suitable, in a drill bushing of the turret disks and with a pin 30 'in the guide bushings 23 or 24 guided tool 30 true to size without changing the hole center distances worn out. The distance between the center distances of the holes can also be through instead of through the gauge blocks placed on the table top a ball gauge 31 can be set, whereby the accuracy is increased.
