    • A drilling head (1) with an axial oscillation generator, includes a mounting (2) for coupling the head to a motor for rotating the mounting about an axis, the mounting (2) having a longitudinal axis (5) coinciding with the axis of rotation of the motor, a tool holder (3), an elastically deformable element (6) for retaining the tool holder (3) in the mounting (2) and an element (7) for guiding the tool holder (3) in the mounting (2) along the longitudinal axis (5) of the mounting, wherein the mounting of the drilling head includes a controlled generator (8) of reciprocating movements in the direction of the aforementioned axis (5) positioned between the mounting (2) and the tool holder, the tool holder and the generator being connected by a longitudinal coupling member (9) suitable for damping the impacts withstood by the tool holder while enabling the transmission of the reciprocating movements.
    • 具有轴向振荡发生器的钻头(1)包括用于将所述头部耦合到马达以将所述安装件围绕轴线旋转的安装件(2),所述安装件(2)具有纵向轴线(5),所述纵向轴线(5)与 电动机的旋转,工具架(3),用于将工具夹具(3)保持在安装件(2)中的可弹性变形的元件(6)和用于将工具架(3)引导到安装件 (2),其中所述钻头的安装包括在位于所述安装件(2)和所述安装件(2)之间的前述轴线(5)的方向上的往复运动的受控发电机(8) 工具架,工具架和发电机通过纵向联接构件(9)连接,该纵向联接构件适合于阻止由工具架承受的冲击,同时能够传递往复运动。
