Definitions

  • the invention relates to a simultaneous grinding machine for grinding centric surfaces of revolution of a shaft, for example bearings or pins of camshafts or crankshafts.
  • the grinding wheel set is provided opposite on the other side of the crankshaft, a single grinding wheel for grinding a support member seat.
  • a support member seat is ground.
  • the single grinding wheel is moved back and support elements are brought into abutment. Subsequently, the bearings are finished with the grinding wheel set.
  • the surfaces of revolution to be ground are divided into two sets of wheels and arranged on opposite sides of the shaft, so that the normal force components of the grinding forces acting on the shaft cancel each other out.
  • a support element can be provided, which is delivered to the workpiece during grinding together with the grinding wheel sets and receives the cutting forces acting on the workpiece in the tangential direction. It must be prewetted for the support element no seats for.
  • the simultaneous grinding machine after Fig. 1 has a workpiece spindle 1 and a tailstock 2 for centrally clamping and driving shafts 3.
  • two grinding spindle 6, 6 ' Provided. These are on Horizontalschlilten 5, 5 'and vertical slide 4, 4' on the machine frame 7 on guides 8 movable.
  • the grinding headstocks 6, 6 ' are delivered in the direction of the X-axis in the opposite direction to the shaft 3, so that the radially acting on the shaft 3 normal force components of the grinding forces cancel each other.
  • the drive of the vertical slide 4, 4 'in the Z direction via ball screws and motors 9.
  • t is also the workpiece spindle 1 via a motor 9' slidably mounted on the machine frame.
  • the first grinding wheel 1 is shown as a shaft 3, a crankshaft. This is processed simultaneously with two grinding wheel sets 10, 10 '.
  • the two grinding wheel sets 10, 10 ' are each composed of a plurality of individual grinding wheels 13. In this way, all centric rotation surfaces 12 to be ground can be finished in a single processing step. Concretely, these are in the crankshaft 7 shown here center bearing, the pin 15 and the Flanschmantel products 16.
  • the widths of the individual grinding wheels 13 and their distances from each other are adapted to the distances and dimensions of the rotation surfaces 12 on the crankshaft.
  • FIG. 2 concerns an arrangement according to claim 3. There are approximately in the middle of the shaft 3 on a rotating surface 12, two individual grinding wheels 13, 13 'simultaneously engaged.
  • the Fig. 3 shows an arrangement according to claim 4, wherein two rotational surfaces 12, two individual grinding wheels 13, 13 'are simultaneously engaged.
  • FIGS. 4 and 5 is the machining of camshafts shown.
  • FIG. 4 corresponds to the feature of claim 5, wherein on all surfaces of rotation 12 of the shaft 3, two individual grinding wheels 13, 13 'are simultaneously engaged.
  • FIG. 5 an arrangement according to claim 6.
  • Fig. 6 the arrangement of a support member 17 is shown. During grinding, this is delivered simultaneously with the individual grinding wheels 13, 13 ', whereby the cutting forces acting on the workpiece in the tangential direction are compensated. While the individual grinding wheels 13, 13 'are delivered in the opposite direction in the X direction, the support element 17 is delivered in the Y direction.
