Description

Handgerät zum Wiederherstellen axial gestauchter Außengewinde an langgestreckten Bauteilen, insbesondere Achskörpern Gegenstand der Erfindung ist ein einfaches Reparatur-Handgerät zum Wiederherstellen axial gestauchter Außengewinde, z. B. an schweren Laufachsen von Fahrzeugen, insbesondere Straßenbahnen.Hand tool for restoring axially compressed external threads on elongated ones Components, in particular axle bodies The invention relates to a simple hand-held repair device to restore axially compressed external threads, e.g. B. on heavy running axles of vehicles, especially trams.

Die Wiederherstellung axial gestauchter Außengewinde mit den bekannten Gewindeschneidvorrichtungen ist nicht möglich. Es sind eine ganze Reihe verschiedenartiger Gewindeschneidkupplungen bekannt, die aber alle nur zum Nachschneiden von seitlich beschädigtem Außengewinde geeignet sind, jedoch nicht zum Wiederherstellen axial gestauchter Außengewinde.The restoration of axially compressed external threads with the known ones Thread cutting devices are not possible. There are quite a few of them Thread cutting couplings known, but all only for re-cutting from the side damaged external thread are suitable, but not for axial restoration compressed external thread.

Es ist zwar unter anderem ein Gerät mit tangential angeordneten, gezähnten Schneidwerkzeugen bekannt, das Führungsrollen aufweist, die aber beim Arbeiten sich drehen sollen und bei axial gestauchtem Gewinde keine ausreichende Zwangsführung ergeben.It is, among other things, a device with tangentially arranged, toothed Known cutting tools, which has guide rollers, but which when working should rotate and if the thread is axially upset, there is insufficient positive guidance result.

Bei verletztem Gewinde bleiben die Gewinderinge erhalten und es wird nur nachgeschnitten. Bei axial gestauchtem Gewinde stimmt der Abstand der Gewinderinge in der Stauchzone nicht mehr und es muß ein neues Gewinde über die Stauchzone hinweg eingeschnitten werden. Das neue Gewinde hat zwar dann nicht die alte Tiefe, aber es ist schraubbar. In der Betriebslage sitzt eine Mutter, z. B. eine Achsmutter, nie am äußersten Ende des Achskörpers. Aber gerade am Ende befindet sich die Stauchzone. Die nicht vorhandene volle Tiefe des Gewindes ist deshalb unschädlich.If the thread is damaged, the threaded rings are retained and it will just recut. If the thread is axially compressed, the spacing between the threaded rings is correct no longer in the compression zone and a new thread has to be made across the compression zone be cut. The new thread will not have the old depth, but it is screwable. In the operating position there is a mother, e.g. B. an axle nut, never at the extreme end of the axle beam. But right at the end is the compression zone. The non-existent full depth of the thread is therefore harmless.

Diesen Übelstand beseitigt bei einem Handgerät zum Wiederherstellen axial gestauchter Außengewinde mit nach Art einer Gewindeschneidkluppe angeordneten, zueinander verstellbaren drei Widerlagern, von denen zwei, an einem Gerätebügel unnachgiebig festgelegte, in die Gewindegänge eingreifende Glieder als Führungsglieder dienen und das dritte radial nachstellbare Glied aus einem tangential wirkenden, in axialer Richtung mehrere Zähne nebeneinander aufweisenden Schneidwerkzeug besteht.This problem eliminates with a handheld device for recovery axially compressed external thread with arranged in the manner of a thread cutting stock, three mutually adjustable abutments, two of which are on a device bracket relentlessly fixed, engaging links in the threads as guide links serve and the third radially adjustable member consists of a tangentially acting, there is a cutting tool having a plurality of teeth next to one another in the axial direction.

Erfindungsgemäß bestehen die Führungsglieder aus an sich bekannten, rollenförmigen oder segmentförmigen Körpern, die während des Schneidvorganges unverdrehbar am Gerätebügel befestigt sind.According to the invention, the guide members consist of known, roll-shaped or segment-shaped bodies that cannot be rotated during the cutting process are attached to the device bracket.

Die Erfahrung hat gezeigt, daß nur ortsfeste nicht drehbare Führungsglieder bei der Arbeit den erforderlichen axial gerichteten Vorschub des Gerätes gewährleisten. Es muß dabei stets vom gesunden Gewinde ausgegangen werden in Richtung zum Ende des das gestauchte Gewinde aufweisenden Körpers hin.Experience has shown that only stationary non-rotatable guide members Ensure the necessary axially directed advance of the device during work. It must always be started from the healthy thread in the direction of the end of the body having the upset thread.

In der Zeichnung ist in Ansicht und teilweisem Schnitt ein Ausführungsbeispiel eines Handgerätes gemäß der Erfindung dargestellt.The drawing shows an exemplary embodiment in view and in partial section a hand-held device according to the invention.

Das gezeichnete Gerät besteht aus einem die beiden rollenförmigen aber während des Schneidvorgangs undrehbar festgelegten Führungsglieder 1 und 2 aufweisenden, das kreisrunde Werkstück 3 umfassenden Gerätebügel 4, der an einem geradlinig geführten Geräteteil s anschließt, welcher mit einer die axial verstellbare Schraubspindel6 enthaltenden, einen Handgriff bildenden Rändelmutter 7 verbunden ist. Die Mittellinie der Schraubspindel 6 deckt sich mit der Symmetrielinie x-x des Gerätes und verläuft durch den Mittelpunkt 8 des Werkstücks 3. Die rollenförmigen Führungsglieder 1 und 2 sind mit ihren Haltebolzen 9 und 10 mittels Klemmsitz an dem Bügel 4 undrehbar festgelegt. Sie sind hinsichtlich ihres Abstandes zur Symmetrieachse x-x lageveränderlich angeordnet, indem die Bolzen 9 und 10 in vorgesehene weitere Bohrlöcher 11, 11' oder 12, 12' eingesetzt werden können. Das in der Richtung des Pfeiles 13 mehrere Zähne hintereinander aufweisende Schneidglied 14 ist auch in axialer Richtung mit mehreren Schneidzähnen versehen, die der jeweiligen Zähnung der Führungsrollen 1 und 2 entsprechen. Der Kopf der Spindel 6, der mittels der Rändelmutter 7 bewegt wird, ist mittels eines Stützgliedes 15 gegenüber dem geradlinig verlaufenden Geräteteil s abgestützt und bewegt sich bei Betätigung der Spindel in einer Schlittenführung 16. Die Spindel ist auswechselbar in der Halterung 17 des Gerätebügels gelagert. Um ein Herausziehen der Spindel zu ermöglichen, ist auch der Kopf der Schraubspindel mit dem Stützglied 15 auswechselbar angeordnet, so daß ein Herausziehen der Spindel nach Lösen der Rändelmutter 18 möglich ist.The device shown consists of a device bracket 4 comprising the circular workpiece 3, which has the two roller-shaped guide members 1 and 2 fixed in a non-rotatable manner during the cutting process, and which connects to a device part s that is guided in a straight line and which forms a handle with a handle containing the axially adjustable screw spindle 6 Knurled nut 7 is connected. The center line of the screw spindle 6 coincides with the symmetry line xx of the device and runs through the center 8 of the workpiece 3. The roller-shaped guide members 1 and 2 are fixed with their retaining bolts 9 and 10 by means of a press fit on the bracket 4 so that they cannot rotate. With regard to their distance from the axis of symmetry xx, they are arranged to be variable in position, in that the bolts 9 and 10 can be inserted into further drilled holes 11, 11 ' or 12, 12' provided. The cutting member 14, which has several teeth one behind the other in the direction of the arrow 13, is also provided in the axial direction with several cutting teeth which correspond to the respective teeth of the guide rollers 1 and 2. The head of the spindle 6, which is moved by means of the knurled nut 7, is supported by a support member 15 against the rectilinear device part s and moves in a slide guide 16 when the spindle is actuated. The spindle is replaceably mounted in the holder 17 of the device bracket. In order to enable the spindle to be pulled out, the head of the screw spindle with the support member 15 is also arranged to be exchangeable, so that the spindle can be pulled out after loosening the knurled nut 18.
