Bei der bisherigen Arbeitsmethode und mit den bisher bekannten Hilfsvorrichtungen bedarf es großer Aufmerksamkeit, wenn man beim Schneiden von Gewinden auf Leit-Spindeldrehbänken ein richtiges Einschalten des Mutterschlosses bewerkstelligen will. Ein jedes Gewinde hat auf der Leitspindel einen periodisch wiederkehrenden Gang, in welchen das Einschalten erfolgen muß. Wird nun inIn the previous working method and with the previously known auxiliary devices Pay close attention when cutting threads on master spindle lathes wants to manage a correct switching on of the mother lock. Each thread has one on the lead screw periodically recurring gear in which switching on must take place. Is now in
ίο die zwischenliegenden Gänge eingeschaltet, so verschiebt sich, der Gewindestahl mehr oder weniger gegen seine frühere Stellung und schneidet nicht da, wo er eigentlich soll. Die Folge davon ist, daß Arbeitsstück und Werkzeug, wenn nicht ganz unbrauchbar, so doch zum mindesten fehlerhaft werden.ίο the intermediate gears switched on, so shifts, the thread steel more or less against its previous position and doesn't cut where it's supposed to. The consequence of this is that work piece and tool, if not completely unusable, then at least become faulty.
Diesem Ubelstand hilft die vorliegende Vorrichtung ab, indem sie ein falsches Einschalten unmöglich macht. Sie besteht aus dem in dieLeitspindel eingreifenden Schneckenrad, welches an der Nabe eine Vertiefung zur Auf nähme eines drehbaren Ringes in . hat, der durch eine auf der Nabe des Schraubenrades drehbare Ringmutter q festgeschraubt werden kann. Eine auf der Schraubenradachse festgeschraubte Scheibe bewirkt, daß das Schraubenrad auf der Achse durch Reibung in seiner Lage gehalten wird. Auf dem Ringe in sind auswechselbare Ringstücke ρ so festgeschraubt, daß sie de.m zu schneidenden Gewinde entsprechende Lücken y bilden. Der Riegel t hat Führung in dem Lager ν und wird durch die Spiralfeder u fortwährend gegen die Gleitschiene χ gehalten. Am Fuße des Riegels t befindet sich eine schräge Fläche wx, welche der ent- ■ sprechenden schrägen Fläche w1 der Gleitschiene χ gegenübersteht. Die Gleitschiene χ ist an der Leitspindelmutter oder, nach der Zeichnung, am Einschalthebel so angebracht, daß sie dieselben Bewegungen wie dieser macht. Der Ring m wird während des ersten Schnittes auf dem Riegel t eingerichtet und durch die Mutter festgehalten. Wenn nun nach dem ersten Schnitt die Leitspindelmutter ausgeschaltet wird, so dreht sich das Schraubenrad und der Ring m; wird nun ein erneuertes Einschalten gewünscht, so drückt man auf den Einschalthebel. Die schrägen Flächen wx und w^ bewirken, daß der Riegel t, sobald eine Lücke y gegenüber ist, sich in diese schiebt. Dadurch läßt sich der Einschalthebel vollends herunterdrücken, und das Mutterschloß ist richtig eingeschaltet.The present device remedies this problem by making it impossible to switch on incorrectly. It consists of the worm wheel engaging in the lead screw, which has a recess on the hub to accommodate a rotatable ring . which can be screwed tight by a ring nut q which can be rotated on the hub of the helical gear. A washer screwed tightly to the helical gear axle ensures that the helical gear is held in place on the axle by friction. Interchangeable ring pieces ρ are screwed onto the ring in so that they form gaps y corresponding to the thread to be cut. The bolt t has guidance in the bearing ν and is held continuously against the slide rail χ by the spiral spring u . At the foot of the bolt t there is an inclined surface w x which is opposite the corresponding inclined surface w 1 of the slide rail χ. The slide rail χ is attached to the lead screw nut or, as shown in the drawing, to the engaging lever so that it makes the same movements as it. The ring m is set up on the latch t during the first cut and held in place by the nut. If the lead screw nut is switched off after the first cut, the helical wheel and the ring m rotate; If you want to switch it on again, press the switch-on lever. The inclined surfaces w x and w ^ cause the bolt t, as soon as a gap y is opposite, to slide into it. This means that the switch-on lever can be fully pressed down and the nut lock is correctly switched on.
Es wird durch diese Vorrichtung bezweckt, ein anderes als beabsichtigtes Einschalten unmöglich zu machen. Dies wird dadurch erreicht, daß der Riegel t an den Ringstücken so lange. Widerstand findet, bis eine Lückey und mithin der richtige Zeitpunkt zum Ein-The purpose of this device is to make switching on other than the intended one impossible. This is achieved by keeping the bolt t on the ring pieces for so long. Resistance is found until a gap y and therefore the right time to enter
schalten gekommen ist, so daß jetzt erst ein Drehen des Einschalthebels χ und somit ein Einrücken der Leitspindelmutter erfolgen kann.switch has come, so that only now the switch-on lever χ can be turned and the lead screw nut can be engaged.
