    • For automatically drilling boreholes within halving joints and frame portions of lattice windows, ejecting glue into said boreholes and inserting dowels, units are proposed, which consist of three dowel inserting devices and three associated glue injecting devices each being operable individually and simultaneously, and which are arranged according to the borehole pattern within the face of a halving joint. For disposing the dowels in magazines and for inserting said dowels into the boreholes in a controlled manner changeable magazines are proposed the bottom of which is arranged above a dowel receiving head and the dowel discharge location is associated to the receiving locations of the dowel receiving head; in this position dowels are transferred into the recesses of the dowel receiving head and are arranged in the discharge position from which they are inserted by means of dowel ejectors into aligned boreholes of a workpiece.
    • 为了自动钻孔在格栅窗的半关节和框架部分内的钻孔,将胶水喷射到所述钻孔中并插入榫钉,提出了单元,其包括三个定位销插入装置和三个相关联的胶注射装置,每个单独和同时操作, 根据在半关节的面内的钻孔图案布置。 为了将榫钉放置在杂志中并以可控的方式将所述榫钉插入钻孔中,提出了可变的杂志,其底部布置在榫钉接收头的上方,并且榫销排放位置与榫钉接收头的接收位置相关联; 在该位置,销钉被转移到定位销接收头的凹部中并且被布置在排出位置,通过定位销弹出器将它们从该位置插入到工件的对准的钻孔中。

    • The dowel hole drilling machine comprises a workpiece support. One part of the workpiece support and a crosspiece carrying the drilling unit are mounted to be pivotally movable in unison about an axis. That workpiece support comprises eccentrically mounted supports, which are adapted to be aligned and flush with the workpiece support and to protrude beyond a workpiece support, which extends at right angles to the workpiece support and is spaced the same distance from the pivotal axis as the workpiece support. The workpiece support serves to support the workpiece during a horizontal drilling operation. When the drilling unit is in a vertical position, the stops are flush with the workpiece support and serve as stops for the drilling of the first row of dowel holes. This results in an exact coordination of the drill and the workpiece support, which constitutes a stop for and defines the location of the reference edge during the horizontal and vertical drilling operations. That coordination will not be changed by the pivotal movement of the drilling unit.
    • 定位钻孔机包括工件支撑。 工件支撑件的一部分和承载钻孔单元的横档安装成围绕轴线一致地枢转运动。 该工件支撑件包括偏心安装的支撑件,其适于与工件支撑件对准和齐平并且突出超过工件支撑件,该工件支撑件与工件支撑件成直角地延伸,并且与工件的枢转轴线间隔相同的距离 支持。 工件支撑件用于在水平钻井操作期间支撑工件。 当钻井单元处于垂直位置时,止动件与工件支撑件齐平,并用作钻头的第一排定位销孔。 这导致钻头和工件支撑件的精确协调,其构成了在水平和垂直钻井操作期间参考边缘的停止并限定了参考边缘的位置。 钻井单位的关键运动不会改变这种协调。
