Description

Gewindemesser mit meßuhr. In der Praxis werden zum Messen von Ge- I winden sogenannte Toleranzlehren benutzt. Diese haben jedoch den Nachteil, daß Mißverständnisse infolge der individuellen Verschiedenheit der mit dem Messen betrauten Personen sich einstellen können. Gemäß der Erfindung wird dieser Nachteil dadurch beseitigt, daß ein besonders ausgebildetes Gewindemeßinstrument mit einer Meßuhr verbunden wird, welches stets das absolute Maß des Gewindes anzeigt.Thread knife with dial gauge. In practice, to measure I used so-called tolerance gauges. However, these have the disadvantage that Misunderstandings as a result of the individual differences between those entrusted with the measurement People can adjust. According to the invention, this disadvantage is thereby eliminated eliminates the need for a specially designed thread measuring instrument with a dial gauge is connected, which always shows the absolute dimension of the thread.

Das Meßinstrument nach der Erfindung, das beispielsweise zum ':Messen von Bolzengewinden bestimmt ist, besteht aus einem Meßkörper, der zwei oder mehrere Meßbacken besitzt, welche durch aus Keilen, konischen Stiften oder ähnlichen Mitteln, die an Federn befestigt sind, voneinander entfernt und durch eine Bandfeder zusammengezogen werden.The measuring instrument according to the invention, for example for ': measuring is determined by bolt threads, consists of a measuring body, the two or more Has measuring jaws, which by means of wedges, conical pins or similar means, which are attached to springs, apart and pulled together by a ribbon spring will.

Ein derartiges --1"Ießinstrutnent hat außer dem bereits angeführten Vorteil den weiteren, daß das Einlegen und Entfernen der Gewindezapfen nicht durch Ein- oder Ausschrauben geschehen muß, sondern daß infolge der Spreizvorrichtung für das Messen die Zapfen lediglich eingelegt und herausgenommen werden können. ! Sinngemäß der Einrichtung nach der Er- j findung für das :liessen von Zapfengewinden I kann auch eine Einrichtung für das Messen von 'Muttergewinden ausgeführt werden, indem der hierzu dienende Meßzapfen z. B. quer oder kreuzweise der Länge nach durchschnitten wird und in die Teilfugen Sperrstücke i eingesetzt werden. ! Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung in einer Abbildung schematisch dargestellt.Such a -1 "Iessinstrutnent has besides the one already mentioned Another advantage is that the insertion and removal of the threaded pin does not occur Screwing in or unscrewing must be done, but that as a result of the spreader for measuring the pins can only be inserted and removed. ! Corresponding to the device according to the invention for: lessening pin threads I can also implement a device for measuring 'nut threads, by the measuring pin serving for this purpose z. B. cut across or crosswise lengthways and locking pieces i are used in the butt joints. ! On the drawing is an embodiment of the invention shown schematically in a figure.

Hiernach besteht das Instrument aus dem Träger a, welcher eine irgendwie geeignete Form erhalten kann. In diesem sind beispielsweise zwei Gewindebacken b und c eingesetzt. Hiervon ist der Backen b durch Schrauben d im Träger befestigt, während der Backen c im Träger verschiebbar angeordnet ist. Der Backen c ist von einer Bandfeder e umgeben, welche den Backen c gegen den Backen b drückt. In die Teilfuge der beiden Backen sind beispielsweise konische Stifte f eingesetzt, durch welche die Backen voneinander entfernt werden. Die Spreizstücke f sind an Blattfedern g befestigt. Mit den Gewindebacken b ist die Meßuhr 1a verbunden, welche jeweils das absolute Maß des zu messenden Gewindebolzens angibt. Zum Einlegen und Herausnehmen des Bolzens werden die beiden konischen Stifte f gegen die Gewindebacken gedrückt, wobei diese sich voneinander entfernen.According to this, the instrument consists of the support a, which can be given any suitable shape. In this, for example, two threaded jaws b and c are used. Of these, the jaw b is fastened in the carrier by screws d, while the jaw c is arranged to be displaceable in the carrier. The jaw c is surrounded by a band spring e which presses the jaw c against the jaw b. In the parting line of the two jaws, for example, conical pins f are used, by means of which the jaws are separated from one another. The expansion pieces f are attached to leaf springs g. The dial gauge 1a is connected to the threaded jaws b and indicates the absolute dimension of the threaded bolt to be measured. To insert and remove the bolt, the two conical pins f are pressed against the threaded jaws, whereby these move away from each other.
