KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
(Westfalen).(Westphalia).
Vorliegende Erfindung bezieht sich auf eine Verbesserung an der durch das Patent No. 47480 geschützten Maschine zum Schneiden des Gewindes an Holzschrauben (Ringschrauben), und zwar besonders auf die Einspannvorrichtung dieser Maschine.The present invention relates to an improvement on that provided by the patent No. 47480 protected machine for cutting the thread on wood screws (eye bolts), especially on the jig of this machine.
Beim Gebrauch der Maschine hat sich nämlich ergeben, dafs die Welle A, zumal bei gröfseren Ringschrauben in dem Moment, in welchem die Spannbacken geöffnet werden, um die geschnittene Schraube herausfallen zu lassen, stillstehen mufs. Zu diesem Zwecke mufste die Construction der Einspannvorrichtung entsprechend geändert werden.When using the machine it has been found that the shaft A, especially in the case of larger eye bolts, must stand still at the moment in which the clamping jaws are opened in order to let the cut screw fall out. For this purpose the construction of the jig had to be changed accordingly.
Die Welle A trägt aufser dem am vorderen Ende angebrachten Centrirstück m und den zu beiden Seiten desselben drehbar befestigten Spannbacken nn eine lose, gleichzeitig als Lagerung für die Welle dienende Hülse a, auf welche die Riemscheibe b und das zum Antrieb der Welle dienende Zahnrad c aufgekeilt ist.On top of the centrir piece m attached to the front end and the clamping jaws nn, which are rotatably attached to both sides of the same, the shaft A carries a loose sleeve a, which also serves as a bearing for the shaft, onto which the pulley b and the gear wheel c used to drive the shaft are keyed is.
An der Hülse α ist seitlich ein Mitnehmerzapfen d und an der Spindel ein in der Längsrichtung verschiebbarer Schieber f befestigt. Zum Oeffnen und Schliefsen der Spannbacken dient gleichfalls eine Stange B, deren vorderes Ende entsprechend der Construction des Haupt-Patentes ausgeführt ist; dieselbe geht durch die hohle Welle A und ist in dem. Schieber f gelagert. Durch den von der Hülse umgebenen Theil der Welle geht eine zweite, concentrisch mit B angeordnete Stange g, welche fast bis an den" Schieber / reicht und von einer Stange q beeinflufst wird, sobald die an der Excenterscheibe C angebrachte Nase ρ gegen die Rolle r stöfst.A driving pin d is attached to the side of the sleeve α and a slide f which can be displaced in the longitudinal direction is attached to the spindle. A rod B, the front end of which is designed according to the construction of the main patent, is also used to open and close the clamping jaws; it goes through the hollow shaft A and is in that. Slide f stored. By the space surrounded by the sleeve part of the wave goes g a second, concentrically arranged with B rod which almost up / enough to the "slide and q of a rod beeinflufst, once the mounted on the eccentric disc C nose ρ against the roller r bump.
Die hierdurch erzielte Wirkung ist folgende:The effect achieved in this way is as follows:
Ist die Schraube geschnitten, so wird die Stange q durch die Nase ρ der Excenterscheibe E nach links gedreht, drückt hierbei die Stange g gegen den Schieber f und bewegt diesen gleichfalls nach links, wodurch der Mitnehmer d frei wird und die Welle A zum Stillstehen kommt.When the screw is cut, the rod q is turned to the left through the nose ρ of the eccentric disk E , pushing the rod g against the slide f and also moving it to the left, as a result of which the driver d is free and the shaft A comes to a standstill .
Bei weiterer Bewegung des Schiebers wird dann auch die Stange B nach links bewegt und die Spannbacken öffnen sich.With further movement of the slide, the rod B is then also moved to the left and the clamping jaws open.
Sobald die neue Schraube wieder eingespannt ist, wird die Stange B' durch die Feder 0 wieder nach rechts getrieben, der Schieber f tritt vor den Mitnehmerzapfen d, so dafs die Welle A wieder an der Drehung der Hülse b theilnimmt.As soon as the new screw is clamped again, the rod B ' is driven to the right again by the spring 0, the slide f steps in front of the driver pin d, so that the shaft A again participates in the rotation of the sleeve b .
