Claims (10)

Patent claims: 1. Method for the automatic movement and alignment of the Bohrtisohes intended for small and medium series parts Vertical drilling machines, in which the Bohrtisoh as a cross-Sohwimmisoh, under which a Sohablonenaufnähme- and scanning device is located, is formed and in which the centering of the Bohrtisohes means one running coaxially to the tool spindle, perpendicular movable bolt takes place, characterized in that the template (12) when the drilling table is stationary (4) is scanned line by line that after finding the conical centering hole coming into the embossing (34) Blown air gets between the sliding parts (6) / 3es of the cross slide (3) and the Bohrtisohes (4), whereupon it is pulled into the remote position by the shortest possible route becomes that at the moment of reaching the working position the supply of blown air is briefly interrupted under relay control, then the precise alignment of the drilling tool (4) is made, and that then the sliding parts (6) of the cross slide (3) and the Bohrtisohes (4), at least be sucked together tightly during the work operation. 2. Apparatus for performing the method naoh claim 1, characterized in that the template (12) on a, the underside of the Bohrtisohes (4) forming plate (11) rests and from below line by line with a on a carriage (23) resiliently arranged feeler and centering pins (39), around which further identification pins (41) are resiliently arranged can be, it can be felt that a conical tip of the feeler and centering pin (39) and one of the identification pins (41) each in a centering hole (34) or Kennzeiohnungslooh (35), the sliding parts (6) Vera German Patent Office without Jedi «2 - Guarantee her <jr.s £ 'n'e A *> f: AriIt of documents which i ^ r Io: oi: ifcci.aiiisdien
