    • Heretofore, dimples or recesses that were distributed over the periphery of a cylindrical wall of a counterbore in a component had to be formed or inserted one after the other, which required complicated positioning work. According to the invention, in order to simultaneously form all of the dimples with a simple positioning device, a deflection body is provided through which at least two milling spindles pass in a planet-like disposition relative to a central control rod. The deflection body is connected to a centering piece facing the counterbore and to an intermediate piece facing away from the counterbore. The intermediate piece in turn forms a type of cylinder/piston connection with a gear housing. Each milling spindle is connected to an output shaft of a gear housing by a flexible shaft that is axially movably guided in between. A relative movement takes place between the housing and the intermediate piece in the course of a predeterminable stroke after the centering piece contacts the base surface of the counterbore. The control rod also performs the relative movement by simultaneously moving the milling spindles radially outwardly in the vicinity of the deflection body.
    • 迄今为止,分布在部件中的沉孔的圆筒壁的周边上的凹坑或凹部必须一个接一个地形成或插入,这需要复杂的定位工作。 根据本发明,为了通过简单的定位装置同时形成所有的凹坑,提供了一个偏转体,通过该偏转体,至少两个铣削主轴相对于中央控制杆以类似行星的方式通过。 偏转体连接到面向沉孔的中心件和面向远离沉孔的中间件。 中间件又与齿轮箱形成一种气缸/活塞连接件。 每个铣削主轴通过柔性轴连接到齿轮壳体的输出轴,该轴可移动地在其间引导。 在定心件接触沉孔的底面之后,在预定行程的过程中,在壳体和中间件之间发生相对运动。 控制杆还通过在偏转体附近径向向外移动铣削主轴来执行相对运动。
