Description

Zum Spannen unregelmäßiger Formstücke sind bereits Spannbacken bekannt, bei deinen in einem, durch einen Klemmmdeckel abgeschlossenen Gehäuse ein Paket achsparalleler, ■. 5 lose aneinanderliegender Spannstifte angeordnet -sind. Diese Spannstifte geben feeinen unbedingt sicheren Halt.Clamping jaws are already known for clamping irregular shaped pieces a package of axially parallel, ■. 5 loosely adjacent dowel pins are arranged. These dowel pins give fine absolutely secure hold.

Bei der neuen Spannbacke sind daher die Innenseiten des die Spannstifte aufnehmenden,.With the new clamping jaw, therefore, the insides of the clamping pins receiving.

rund oder rechteckig ausgearbeiteten Gehäuses mit Gewinderiefen versehen, die zum Festhalten der Spannstifte dienen. Die Spannstifte tragen Außengewinde. Ihr Spannende ist abgerundet: und · ihr · anderes Ende mitround or rectangular case provided with thread grooves that are used to hold the dowel pins in place. The dowel pins have external threads. Your exciting is rounded: and · her · other end with

ig einem Vierkantloch für einen Stellschlüssel versehen. Es werden so viel Spannstifte in das Spannbackengehäuse eingesetzt, daß das Gehäuse voll ausgefüllt wird. Die außenliegenden Spannstifte greifen mit ihrem Gewinde inig a square hole for an adjusting key. There are so many dowel pins inserted into the jaw housing that the housing is filled out in full. The outlying ones Dowel pins engage with their thread

ao die Gewinderiefen des Spannbackengehäuses, wodurch eine starre und unnachgiebige Verbindung zwischen dem Spambackengehäuse· und den Spannstiften hergestellt wird. Eine Seite des Spannbackengehäuses ist als. Deckel oder Klemmstück ausgebildet und an der Innenfläche gleichfalls mit Gewinderiefen versehen. Das Klemmstück kann durch in den Seitenwänden des Gehäuses gelagerte Schrauben nach Belieben .angezogen oder gelöst werden. Die neue Spannbacke ist für Drehbankfutter, Planscheiben und auch Schraubstöcke verwendbar und in der Zeichnung in drei Schnitten dargestellt.ao the thread grooves of the jaw housing, creating a rigid and unyielding connection between the spam jaw housing and the dowel pins is made. One side of the jaw housing is as. lid or clamping piece and also provided with thread grooves on the inner surface. The clamping piece can be mounted by in the side walls of the housing Screws can be tightened or loosened as required. The new jaw is Can be used for lathe chucks, face plates and also vices and shown in the drawing shown in three sections.

Das zentrische Spannen eines Formstückes geschieht wie folgt:The centric clamping of a fitting is done as follows:

Alle achsparallel liegenden Spannstifte der zwei gegeneinanderstehenäen Spannbacken werden auf die gleiche. Höhe geschraubt, damit die Spannstifte zwei gegenüberliegende Flächen bilden. Nun wird das Formstück zwischen die zwei Spannflächen gesetzt und leicht angezogen. Hierauf beginnt, das zentrische Ausrichten des Formstückes. Dazu nimmt man nur so viel Spannstifte, wie unbedingt nötig sind, denn schon mit wenigen Spannstiften ist ein leichtes und schnelles Ausrichten möglich. Hat man die gewünschte Stellung des Formstückes erreicht, dann werden auch die restlichen Spannstifte leicht, nur auf Fühlung, an den Körper des Form- 5« Stückes herangeschraubt. Nunmehr werden die Klemmstücke mittels der Gehäuseschrauben festgezogen, und alle Spannstifte sind dadurch fest miteinander verbunden. Ein Nachgeben ist in dieser Stellung der Spannstifte nicht mehr möglich. Es kann nun die Bearbeitung des eingespannten Formstückes beginnen. All axially parallel clamping pins of the two opposing clamping jaws be on the same. Screwed in height so that the dowel pins are two opposite one another Form surfaces. Now the fitting is placed between the two clamping surfaces and slightly tightened. Then the centric alignment of the fitting begins. In addition you only use as many dowel pins as are absolutely necessary, because with just a few Quick and easy alignment is possible with clamping pins. You have the one you want Position of the shaped piece reached, then the remaining dowel pins are easy, only by touch, to the body of the form- 5 " Screwed on. Now the clamping pieces are fastened by means of the housing screws tightened, and all the dowel pins are firmly connected to each other. A yield is no longer possible in this position of the dowel pins. You can now start editing of the clamped fitting.
