Description

Die Erfindung bezieht sich auf ein Verfahren~ zum Messen von auf einer Werkzeugmaschine hergestellten Schnittflächen, insbesondere von durch Gewinderolimaschinen hergestellten Gewindefianken od. dgl. Bei diesen letzteren Maschinen beispielsweise erfolgt bekanntllich die Herstellung des Gewindes so, daß der ohne Spanabnahme mit Ge winde zu versehende Gegenstand, etwa ein Bolzen, zwischen zwei einander gegenüberstehenfden, das Arbeitsgewinde tragenden Rollscheiben eingeführt wird, von denen die eine feststehend angeordnet ist, während die andere nach Maßgabe der fortschreitenden Eingriffstiefe des Werkstückes an die erstere Scheibe angenähert wird. The invention relates to a method for measuring A machine tool produced cut surfaces, in particular by thread rolling machines Manufactured threaded joints or the like. In these latter machines, for example As is known, the production of the thread is carried out in such a way that it can be removed without cutting Thread the object to be provided, such as a bolt, between two opposing Rolling disks bearing the working thread are introduced, one of which is stationary is arranged, while the other according to the progressive depth of engagement of the workpiece is approached to the former disc.

Bisher war es nun üblic'h, heim Rollen je nach der gewünschten Genauigkeit die Gewindeflanken etwa jedes fünften Werkstückes mit dem Flankenmikrometer nachzumessen. Diese Messung bedeutet eine Unterbrechung der Arbeit, die je nach der Geschicklichkeit des messenden Arbeiters der Herstellungszeit von drei bis sechs und mehr Gewinden entspricht. Überdies ist das Ergebnis der Messung weitgehend von der Geschicklichkeft und Verläßlichkeit des Betreffenden bei der Handhabung des Mikrometers abhängig. Dabei haben natürlich Gewindefehler zwischen zwei Messungen die Unbrauchbarkeit der betreffenden Werkstücke zur Folge. Kurz, bei der bisherigen Prüfungs,weise muß neben großen Zeitverlusten mit viel Ausschluß gerechnet werden. So far it has been customary to roll home depending on the desired accuracy Measure the thread flanks of about every fifth workpiece with the flank micrometer. This measurement means an interruption of work, depending on the skill manufacturing time measuring worker from three to six and more threads is equivalent to. Moreover, the result of the measurement is largely on the skill level and reliability of the person concerned in handling the micrometer. Thread errors between two measurements are of course useless of the workpieces concerned. In short, in the previous exam, wise must In addition to large losses of time, a lot of exclusion can be expected.

Dieser Mangel wird gemäß der Erfindung behoben, daß man die bearibeiteten Flächen insbesondere automatisch dem fortschreitenden Arbeitsvorgang stetig folgend abtastet und den Meßwert in irgendeiner an sich bekannten Weise anzeigt. An der Maschine wird z. B. eine Meßuhr vorgesehen, deren Meßstange während des Arbeitsvorganges an dem Vorschub des beweglichen Werkzeuges teilnimmt und deren Bewegung an der Meßuhr abgelesen werden kann. Durch entsprechende Einstellung der für diesen Zweck an der Maschine ubhcherweise vorgesehenen Ein- und Ausschaltvorrichtungen kann die Ausschaltung des Rollscheibenvorschubes erfolgen, wenn der Zeiger auf der Meßuhr in den Bereich zwischen zwei die Toleranz anzeigende Marken gelangt. This deficiency is remedied according to the invention that one the processed Surfaces in particular automatically continuously following the progressing work process scans and displays the measured value in any manner known per se. At the Machine is z. B. a dial gauge is provided, the measuring rod during the operation participates in the advance of the movable tool and its movement on the dial gauge can be read. By setting the for this purpose at the The machine can switch off the switch-off devices provided in the form of increments of the roll disc feed when the pointer on the dial indicator is in the range gets between two marks indicating the tolerance.

Die Zeichnung veranschaulicht eine gemäß der Erfindung ausgestattete Gewinderollmaschine Auf dem Maschinenbett I sind in irgendeiner bekannten Weise die angetriebenen Gewinderollscheiben 2, 3 angeordnet. Die Rollscheibe 2 ist feststehend angebracht, während die Rollscheibe 3 mittels eines Trägers 4 und eines Schlittens 5 quer zur Achse des zu bearbeitenden Werkstückes, etwa eines Bolzens 6 (in Richtung der Pfeile x, y), verschiedlich ist. Beim Einrollen des Gewindes wird die bewegliche Rolischeibe 3 in der Zeichnung nach links bewegt. Am Träger 4 ist ein Anschlagswinkel 7 vorgesehen, in dessen Nähe eine an sich bekannte Meßuhr8 derart feststehend angeordnet ist, daß die Meßstangeg, deren Axialbewegung auf den Zeiger IO der Uhr übertragen wird, durch Federdruck od. dgl. während des Arbeitsvorganges in Anlage an dem Anschlag7 gehalten werden kann. In der Zeichnung ist in vollen Linien der Anschlag 7, die Meßstange g und der Zeiger IO am Ende des Rcllvorganges dargestellt, während die Ausgangslage der genannten Teile einpunktiert ist. The drawing illustrates one equipped according to the invention Thread rolling machine on the machine bed I are in some known way the driven thread rolling disks 2, 3 arranged. The rolling disk 2 is stationary attached, while the rolling disk 3 by means of a carrier 4 and a carriage 5 transversely to the axis of the workpiece to be machined, for example a bolt 6 (in the direction the arrows x, y), is different. When the thread is rolled in, the movable Roller disk 3 moved to the left in the drawing. On the carrier 4 is a stop bracket 7 is provided, in the vicinity of which a dial gauge 8 known per se is arranged in such a fixed manner is that the Meßstangeg, whose axial movement is transferred to the pointer IO of the clock is, by spring pressure or the like. During the work process in contact with the stop7 can be held. In the drawing, the stop 7 is in full lines, the Measuring rod g and the pointer IO shown at the end of the Rcllvorganges, while the Starting position of the parts mentioned is punctuated.

Nach jedemArbeitshuh wird die Meßuhr in irgendeiner geeigneten Weise, z. B. in Abhängigkeit von der beweglichen Rolllscheibe, in die Ausgangsstellung zurückgestellt.After each work shoe, the dial indicator is adjusted in any suitable way, z. B. depending on the movable roller disc, in the starting position deferred.
