So that drilling machines with at least two drilling spindles with coupling pieces for drills can be reset to changed patterns of drill holes, an adapter is provided which consists of a housing with two input shafts (15, 16) parallel to one another, the spacing of which corresponds to the spacing of the two drilling spindles and the shape of which corresponds to the shanks of the drills to be fastened in the drilling spindles. Drilling spindles (17, 18) or groups of drilling spindles (17, 26) connected to one another by gearing and having coupling pieces for drills are arranged on the opposite side of the housing, of which each or each group is in drive connection with one of the two input shafts (15, 16). <IMAGE> |
