Definitions

  • the invention relates to a grinding machine with a substructure, corresponding grinding units and a driven workpiece spindle unit for optionally simultaneous internal, external and / or surface grinding of workpieces.
  • ground workpieces in particular of rotationally symmetrical workpieces such as gears or the like, are subject to ever increasing demands.
  • the desire for improved parallelism, perpendicularity, concentricity and coaxiality of ground bores, spigots and flat surfaces with each other comes first.
  • DE-U-1 695 503 shows that, without reclamping the workpiece, it can be ground internally and externally at the same time, in that two grinding heads, which can be set independently of one another and relative to the workpiece headstock, are constructed on separate slides.
  • the inner grinding body can be inserted into the centrally clamped workpiece from one side in order to then polish the pre-ground surface from the opposite side by means of the stationary disc.
  • the aim of the present invention namely to reduce the machining time of both internally and externally round workpieces and possibly to be ground flat with maximum grinding accuracy, is not achieved by any of the grinding machines described above.
  • a key feature is the center bearing, which is designed as a hydrodynamic or hydrostatic sliding support bearing. Such a center bearing is not yet known and had to be developed with considerable effort.
  • US-A-2 142 020 specifies a center bearing, but the construction disclosed there with a normal chuck and conventional bearing surfaces does not allow the required grinding accuracy. While even a ball bearing in the best case achieves a concentricity of 5 my, concentricity values of 1 my measured at the centering collar of the central bearing are achieved with the hydrodynamic / hydrostatic slide support bearing according to the invention. These values can be maintained even after a long period of operation, while the bearings known up to now soon deteriorate due to wear.
  • the workpiece is not reclamped even then.
  • the use of the center bearing allows a variety of variations. Depending on the workpiece, a wide range of different units can be arranged on both sides of the common substructure.
  • the workpiece spindle unit 3 which allows the workpiece to be clamped in the center, so that internal grinding units 4, 4 'and external grinding units 5, 5' can simultaneously machine the workpiece 6 on both sides.
  • the directions of rotation of the workpiece spindle and the grinding wheels are expediently chosen so that they are in opposite directions.
  • 5 schematically indicates how the parts in contact with one another move towards one another. While the workpiece 6 rotates clockwise, the inner grinding body 7 rotating in the counterclockwise direction engages on the right side and the outer grinding body 8 rotating in the clockwise direction engages on the left side. In this way, the greatest relative speed to each other is achieved.
  • FIG. 4 shows the structure of the center bearing 3, which is designed as a hydrodynamic slide support bearing and is driven by the motor 9 via V-belts 10 in the center of the bearing.
  • a concentricity ⁇ 1 my, measured on the centering collar of the center bearing, and a long service life can be achieved.
  • a double membrane chuck can be used as the clamping device, which grips the workpiece on the outside diameter.
  • the example shown in FIG. 3 relates to the simultaneous drilling and external grinding of a gear block 11 and corresponds in principle to the diagram according to FIG. 1.
  • the concentricity of the toothing to the ground bores or pegs is an essential prerequisite for a quiet running, which is mainly in Automotive transmissions matter.
  • the grinding machine according to the invention fulfills the desire for an optimal concentricity.
  • the gear block 11 is tensioned on both sides with roller cages which contain rollers provided with a bore and wound on wires, which in turn are fastened in a brass ring.
  • a simultaneous drilling, external and face grinding is shown as an example in FIG. 6.
  • the modular principle is used for this in the grinding machine according to the invention.
  • the machine bed is a torsionally rigid welded construction, while the upper and lower carriages of the individual structural units 4, 5, 4 ', 5' consist of cast iron. All units have hardened guideway strips and slide roller bearings.
  • the workpiece spindle bearing 3 can also be moved on the machine bed relative to the grinding units 4, 5, so that a two- or multi-station machine is created.
  • the workpiece does not have to be reclamped so that optimum manufacturing accuracy is still achieved.
