KOMBINIERTES BOHR-GEWINDE-SENK-WERKZEUGCOMBINED DRILLING, THREAD AND COUNTERSINGING TOOL
Es 1st bekannt, daß Gewindelöcher unter anderem wie folgt hergestellt werden:It is known that threaded holes are made, among other things, as follows:
1) Bohren des Kernloches mittels Spiralbohrer Im ersten Arbeltsgang· Ansenken Im zweiten Arbeltsgang» Gewindeschneiden Im dritten Arbeitsgang. Alle Arbeitsgänge werden voneinander getrennt durchgeführt.1) Drilling the core hole with a twist drill in the first working gear · Countersinking in the second working gear » Thread cutting in the third step. All operations are carried out separately from one another.
2) Bohren des Kernloches und Ansenken mittels kombiniertem Bohr-Senk-Werkzeug mit gleichem Arbeitsvorschub im ersten Arbeitsgang. Gewindeschneiden im zweiten Arbeitsgang.2) Drilling the core hole and countersinking using a combined drilling and countersinking tool with the same working feed rate in the first step. Thread cutting in the second step.
3) Bohren und Gewindeschneiden mit kombiniertem Spiralgewindebohrer in einem Arbeitsgang - ohne Ansenken.3) Drilling and tapping with a combined spiral tap in one operation - without Countersinking.
Es sind bereits Senker bekannt, die auf Spiral- oder Gewindebohrer aufgesetzt werden, wobei die Schenkel des Senkers in den Spannuten geführt werden (Gratex). Dieser Senker baut im Rechtslauf die Kraft auf und fast bei Linkslauf des Gewindebohrers an. Diese Einrichtungen sind jedoch für kombinierte Spiralgewinde-Werkzeuge infolge des bei diesen Werkzeugen erforderlichen Drallwinkels nicht verwendbar.There are already known countersinks that are based on spiral or Taps are placed, the legs of the countersink being guided in the flutes (Gratex). This countersink builds up the force in clockwise rotation and almost with counterclockwise rotation of the tap. These bodies however, are for combined spiral thread tools due to the necessity of these tools Helix angle cannot be used.
Das vorliegende Werkzeug ist dadurch gekennzeichnet, daß Gawindelöcher mit Ansenkung in Einern Arbeitsgang hergestellt werden.The present tool is characterized in that Gawindelöhren with countersink in one operation getting produced.
ι,ι,
Es besteht aus einem kombinierten Spiralgewindebohrer (1), auf dessen gemeinsamen Schaft eine Hülse (2) und ein darin federndes Senkwerkzeug aufgesetzt uinU. Die Hülse wird mit den beiden Schrauben (4) gegen radiale Verdrehung und axiale Verschiebung abgesichert. Der Senkorteil (3) wird durch die Schrauben (5) gegen radiale Verdrehung gesichert und ist so ausgebildet, daß er infolge zweier Längsnuten axial federnd gegen eine Spiralfeder (6) verschiebbar ist.It consists of a combined spiral tap (1), a sleeve (2) and a resilient countersinking tool, uinU, are placed on its common shaft. The sleeve is secured against radial rotation and axial displacement with the two screws (4). The sinker part (3) is secured against radial rotation by the screws (5) and is designed so that it is axially resiliently displaceable against a spiral spring (6) due to two longitudinal grooves.
Die Funktion besteht darin, daß der Senker in gleicher Schnittrichtung mit dem Gewindewerkzeug schneidet und der Steigung des Gewindebohrers entsprechend bis zu der zur Ansenkung erforderlichen Schnittkraft zusammenfedert. Die Vorspannung der Federkraft läßt sich durch die fest auf dem Schaft befindliche Außenhülse axial verändern.The function is that the countersink cuts in the same cutting direction with the threading tool and according to the pitch of the tap up to the cutting force required for countersinking. The preload of the spring force can be axially through the outer sleeve located firmly on the shaft change.
