Definitions

  • the invention relates to a device, comprising a cutter holder, which interchangeably accommodates at least one cutting edge, for turning machined ball cages for constant velocity joints with spherical ring-shaped inner and outer bearing surfaces.
  • constant velocity joints are known in particular in connection with motor vehicles. Steered wheels are driven in front wheel drive vehicles. For this reason, front or, if necessary, rear wheel axle shafts must have joints that allow both the compression and rebound of the wheels and their steering angle. Therefore, constant velocity joints are used to enable the wheels to be driven as uniformly as possible.
  • constant velocity fixed joints designed as cup joints are used here, while in the case of joints on rear axle shafts, constant velocity sliding joints designed as cup joints are used which, in addition to bending the joint, enable axial displacement.
  • the ball cages provided with spherical inner and outer bearing surfaces and ball pockets for receiving the torque-transmitting balls are first produced in a variety of rolling, forging, punching and turning operations on various machines as blanks. Starting from these blanks, the Finishing of the ball cages then in turn in a multitude of work steps on different machines, with grinding processes for machining the bearing surfaces and for machining the contact surfaces being used in particular as machining processes. It is also known from the prior art to use the turning machining method instead of the grinding method as a machining method. Here it is known to use CNC-controlled lathes, the cutting edge holder of which is arranged to be continuously movable in the translatory direction.
  • the invention is therefore based on the object of providing a device for turning ball cages intended for constant velocity joints, which allows simple, inexpensive and fully automated production while observing the narrowest tolerances.
  • the solution of this task is characterized according to the invention characterized 'in that the blade holder onto a machining plane lying in a pivot point is movable relative rotationally within the working plane.
  • the device according to the invention includes a cutter holder that has at least one cutting edge that can be exchanged and that can be rotated within the processing plane.
  • a cutter holder that has at least one cutting edge that can be exchanged and that can be rotated within the processing plane.
  • this creates the possibility of forming both the inner and the outer spherical bearing surfaces while always maintaining the same pressure angle of the cutting edge to the workpiece to be machined. It is hereby achieved that regardless of the position of the cutters held by the cutter holder, the surface is always processed in the same way. This ensures compliance with tolerances within very narrow limits.
  • the axis of rotation of the ball cage lies in the working plane. This ensures that a movement carried out by the cutting holder leads to a precisely specifiable surface treatment. The precise reproducibility of a high Geometry accuracy and a high surface quality bearing surface is thus ensured.
  • the translational movement of the cutter holder is possible in two directions that are linearly independent of one another. Additional reclamping of the ball cage to be machined is avoided in this way, since the cutter holder can approach every point of the ball cage to be machined. Furthermore, it is proposed according to the invention that a circular movement of the cutting edge holder can be carried out around a pivot point within the working plane. In this way it is ensured that, in addition to the accessibility of each surface point of the ball cage to be machined, the machining edge can be placed on the workpiece at a constant angle. The formation of spherical bearing surfaces, both the inner and the outer, is thus carried out according to the invention while adhering to narrow tolerances and avoiding wear-related uneven wear.
  • the cutting edge holder can be moved linearly to form the front-side contact surface and the cylindrical receiving surface, all machining operations being able to be carried out with one and the same device. This avoids unnecessarily frequent reclamping of the ball cage. It is shown overall that the turning can be carried out on the same lathe, it being only necessary to machine the different surfaces in a first step to form the inner bearing surface as well as the receiving surface and the contact surface and to produce the outer bearing surface in a second step.
  • the turning process can be carried out on the same machine on the one hand and the cutter holder can also be moved both translationally and rotatably within the processing plane, it is possible to use the device according to the invention fully automatically, quickly and inexpensively while maintaining the tightest tolerances to form individual ring areas.
  • the blade holder In addition to the rotational and translational movability of the cutting edge holder within the working plane, it advantageously also has an additional possibility of movement. This consists in 'that the blade holder is movable along the feed axis in a small area. This enables the ball radius to be precisely defined, for example if the cutting edges have changed due to wear. A continuous movement of the cutter holder is also possible, so that geometries deviating from the circular geometry can also be generated in partial areas.

As a result, an optimally designed surface can be produced in compliance with the tightest tolerances. In addition, inaccuracies that occur as a result of wear of the cutting edges can be compensated for by simply readjusting the cutting tool.
  • cutter holders 9 and 10 shown by way of example in the figures with the cutters 11 to 14 or 17 and 18 arranged on the cutter holder head, it is of course also possible to use differently designed cutter holders. It is only essential that the cutter holder is not only translational but also rotatable with respect to a pivot point that lies in a plane defined by the axis of rotation of the ball cage 1 to be machined, so that any point on the workpiece always has the same angular geometry of the cutting edge Workpiece can be approached. This creates the possibility of also manufacturing individual ring areas while maintaining extremely tight tolerances.
  • the rotational mobility as well as the translational mobility relates to a relative movement between the cutting edges and the workpiece, and can therefore also be realized by moving the workpiece relative to the tool or by combined movements of the two. LIST OF REFERENCES
