Description
Vorschubsystem für Werkzeugmaschinen, insbesonders für Kleindrehbänke.Feed system for machine tools, especially for small lathes.
Beschreibung.Description.
Nach dem derzeitigen Stand der Technik wird der Längsvorschub bei Drehbänken bewirkt, 1. durch die Leitspindel unter Verwendung einer geteilten Mutter zum Schneiden von Gewinden, 2. durch die Zugspindel mit Fallschnecke und Zahnstange als Hauptelemente für den Zerspahnungsvorschub. Die Bedinung dieser beiden Systeme er= fordert, durch ihre Verschiedenheit bedingt, jeweils eine gesonderte Schaltung. Damit keine Doppelschaltung erfolgen kann, (welche zum Bruch führen könnte) baut man zur Sicherung wachselseitige Block= kierungen ein. Nach der Erfindung ist eine solche Fehlschaltung nicht möglich, da das einzige Element der Schlittenbewegung die Leitspindel in der Umdrehung, als auch im Stillstand ist.According to the current state of the art, the longitudinal feed is at Lathes effected 1. by the lead screw using a split nut for cutting threads, 2. through the pull spindle with drop screw and toothed rack as the main elements for the cutting feed. The condition of these two systems he = requires, due to their differences, a separate circuit in each case. So that no double switching can take place (which could lead to breakage) builds blockings on the wax side are used to secure them. According to the invention is one such incorrect switching is not possible, as the only element of the slide movement the lead screw is rotating as well as at a standstill.
Besondarx bei den Kleindrshbanken ist das Unterbringen ton Leit und Zugspindel it Zahnstangenantrieb selten und wird auf die kleinen Abmessungen im Getriebekasten des Schlittens zurückzuführen setn.Particularly in the case of the small banks is the accommodation of the Leit und Pull spindle with rack and pinion drive is rare and is based on the small dimensions in the Setn back the slide's gear box.
Dem Antragsteller ist es gelungen bei den kleinen Abmessungen einer Tischdrehbank (siene Foto) nicht nur Leit= und Zugspindelantrieb mit Eilrücklauf, sodern auch den durch Zugspindelantrieb bewirkten Planvorschub unterzubringen. Sollte es sich für das Patentamt als notwendig erweisen, die Überprüfung der Erfindung und deren prack= tischen Anwendung am fertigen Modell (Foto) vorzunehmen, sosteht dieses auf Anforderung jederzeit zur Verfügung. Durch Kraftstecker und eingebauten Motor immer Betriebsfertig.The applicant succeeded with the small dimensions of a Table lathe (see photo) not only guide and pull spindle drive with rapid return, but also to accommodate the face feed caused by the tension spindle drive. Should it may prove necessary for the patent office to review the invention and to make their practical application on the finished model (photo), see this is available on request at any time. By power connector and built-in Engine always ready for use.
Beschreibung der Zeichnung Durch ein Schaltgetriebe, in dem am Spindelstock angebrachten Räderkasten (a) kann der Vorschub wahlweise auf die Leitspindel (b) als auch auf die Zugspindel (c) übertragen werden. Die zugleich auch als Zahnrad ausgebildete Leitepindelmutter (d) ist in doppelter Lagerung im Räderkasten (e) des Supports untergebracht und wird über den Untersetzungstrieb (f) durch die Zugspindel zum rotieren gebracht und bewirkt den Zerspahnungsvorschub. Hierbei ist die Leitspindel durch die Bremsschraube (g) soweit zu bremsen, das ein mitlaufen der Spindel nicht erfolgen kann. Ist die Leitspindel, wie bei Kleindrehbänken üblich, mit Handverstellung (h) versehen, soist auch bei eingeschaltetem Vorschub eine Längsverstellung von Hand in jeder Richtung möglich. Wird nun die Leitspindel zum Ge= windeschneiden benutzt, so ist durch den Schalthebel (i) das Zug= spindelritzel (j) auszuschalten. Gleichzeitig bewirkt ein an der Schaltstange (k) angearbeitetes Zahnsegment (1) die Blockierung der Leitspindelmutter gegen Drehung. Den Eilrücklauf bewirkt der Schalthebel (m) wenn dieser beim Zerspahnugsvorschub die Leitspindel einschaltet. Description of the drawing By a gearbox in which on the headstock attached gear case (a), the feed can optionally be transferred to the lead screw (b) as well as to the tension spindle (c). At the same time as a gear trained lead screw nut (d) is in double bearings in the gear case (e) of the support and is via the reduction drive (f) through the tension spindle made to rotate and causes the cutting feed. Here is the lead screw brake with the brake screw (g) so that the spindle does not run can be done. Is the lead screw with manual adjustment, as is usual with small lathes (h), a longitudinal adjustment of Hand possible in any direction. Now the lead screw is used for thread cutting is used, the pull = spindle pinion (j) must be switched off using the switch lever (i). At the same time, a toothed segment (1) attached to the shift rod (k) the locking of the lead screw nut against rotation. The causes the rapid return Switching lever (m) when this switches on the lead screw during the cutting feed.
