Abstract

Die Erfindung betrifft ein Gerät zum Einschleifen von Gewinde oder anderen Hinterschneidungen in vorgebohr­ tes Stein- oder dergleichen Material. An einem Stativ (1) ist in einer Gewindebuchse (2) eine Gewindespindel (3) schraubbar angeordnet. An dem einen Ende der Gewinde­ spindel (3) ist eine Dreheinrichtung, vorzugsweise eine Handkurbel (4), vorgesehen, während an ihrem anderen Ende achsparallel ein Triebwerk (5) angeordnet ist. Das Triebwerk (5) ist mit der Gewindespindel (3) achsparallel seitlich versetzbar und in jeder beliebigen Versetzungs­ position feststellbar verbunden. Die Triebachse des Trieb­ werkes (5) ist mit einer Werkzeugaufnahme für die aus­ wechselbare Halterung eines rotierenden Werkzeuges, bei­ spielsweise einer Schleifscheibe (7) ausgerüstet. Das un­ tere Ende des Werkzeugschaftes ist nach innen zur Schleif­ scheibe (7) hin abgesetzt, wobei dieser abgesetzte Ab­ schnitt ein gegen die Drehrichtung steigendes Gewinde aufweist, während in der Schleifscheibe (7) eine Gewin­ dehülse mit einem auf das Gewinde des Werkzeugschaftes passenden Innengewinde angeordnet ist. The invention relates to a device for grinding in Threads or other undercuts in pre-drilled stone or similar material. On a tripod (1) a threaded spindle (3) in a threaded bushing (2) arranged screwable. The thread at one end Spindle (3) is a rotating device, preferably one Hand crank (4) provided while on her other An engine (5) is arranged axially parallel to the end. The Engine (5) is axially parallel with the threaded spindle (3) laterally displaceable and in any displacement position locked connected. The drive axis of the shoot werkes (5) is out with a tool holder changeable holder of a rotating tool, at for example equipped with a grinding wheel (7). The un The end of the tool shank is inward for grinding disc (7) down, this offset Ab cut a thread rising against the direction of rotation has, while in the grinding wheel (7) a gain with one on the thread of the tool shank matching internal thread is arranged.

Die Schleifscheibe (7) weist einen unteren Gewinde­ schleifrand mit dem Profil des gewünschten Gewindes und einen oberen Korrektursockel auf, wobei der Durchmesser des Korrektursockels um die Tiefe der Gewindegänge klei­ ner ist, als der Durchmesser des Gewindeschleifrandes. The grinding wheel (7) has a lower thread grinding edge with the profile of the desired thread and an upper correction base, the diameter of the correction base around the depth of the threads ner than the diameter of the thread grinding edge.
