Definitions

  • the invention relates to a device for grinding and / or finishing a workpiece received on and / or in at least one workpiece holder, wherein the workpiece and the workpiece holder can be set into an oscillating motion with a drive device and form an oscillating unit or form part of an oscillating unit.

  • the counteracting to the oscillating movement of the oscillating unit counterbalancing unit causes the resulting by the oscillating movement of the workpiece and the workpiece holder inertial forces can be compensated by opposite inertial forces are generated to these inertial forces.
  • components adjacent to the oscillating unit and the compensation unit such as a machine bed of the device, are decoupled from vibrations.
  • This in turn has the advantage that the environment of the device is vibration-free. It can be achieved at a oscillation of +/- 1.0 mm very high oscillation frequencies in the range of 1500 min -1 .
  • the oscillating unit oscillates along a first axis and the compensation unit in a second axis parallel to the first axis.
  • the parallelism of the axes ensures that the inertial forces generated by the oscillating movements of the oscillating unit and the compensation unit can be compensated.
  • the axles need not be physically trained; the axes are defined by the movement of the respective center of gravity of the oscillating unit and the compensation unit.
  • first and the second axis are coaxial with each other. This has the effect that the moments of inertia resulting from the oscillating movements of the oscillating unit and the compensation unit can also compensate each other. As a result, the device according to the invention and its surroundings are completely vibration-free.
  • a complete compensation of inertial forces and moments can be achieved in particular if the mass of the oscillating unit is equal to the mass of the compensation unit and if the oscillation stroke of the oscillating unit is equal to the oscillation stroke of the compensation unit.
  • the Oszillationshub corresponds to the oscillation amplitude and is for example a few millimeters. It is also possible to generate a complete compensation of the inertial forces, if the mass of the oscillating unit to the mass of the compensation unit is different. In this case, the oscillation strokes can be adjusted accordingly. For example, the mass of the oscillating unit is half the mass of the compensation unit, wherein the oscillation stroke of the oscillating unit corresponds to twice the oscillation stroke of the compensation unit.
  • the device according to the invention may comprise a headstock and / or a headstock support, a tailstock and / or a tailstock support and / or a workpiece rotation drive, wherein said components may be part of the oscillating unit. So it is not necessary to reduce the mass of the oscillating unit to a minimum, but also the said components can oscillate together with the workpiece and the at least one workpiece holder.
  • the corresponding compensation of the oscillating movement of the thus formed oscillating unit can be effected by a compensation unit whose stroke and / or mass is adjusted accordingly.
  • the headstock and the tailstock are arranged on a common carrier, the Part of the oscillating unit is. This is particularly advantageous for small workpieces.
  • the term "workpiece holder” is understood to mean a component which is suitable for at least defining the position and / or spatial position of a workpiece to be machined.

  • the compensating body advantageously has fastening possibilities for further mass bodies.
  • the mass of the compensation unit can be adjusted particularly easily by attaching the compensation body, parts thereof or additional massed parts to or on the carrier.
  • the compensating body and / or the headstock and / or the tailstock are linearly guided.
  • the components mentioned can thus oscillate freely in the longitudinal direction of the linear guide, it being ensured that the components can not build up any vibrations, which are oriented transversely to the longitudinal axis of the guide.

  • linear guide or the linear guides are provided on or in a carrier carriage, which is preferably mounted displaceably relative to a machine bed of the device.
  • the drive device which sets the oscillating unit in an oscillating motion also drives the compensation unit. This has the advantage that it is possible to dispense with an additional drive, as a result of which the device has fewer components as a whole.

  • crank members are provided for driving the oscillating unit and for driving the compensation unit, whereby it is possible, for example, to spatially decouple the oscillating unit and the compensation unit from each other.
  • crank links can be coupled to one another via traction means, friction and / or gears.
  • both the drive for the oscillating unit and for the compensation unit can be created with a drive and spaced apart crank members.
  • the drive device and / or the auxiliary drive can also have a linear drive, in particular a pneumatically and / or hydraulically actuated cylinder or a linear motor. With such drives, therefore, not a rotary motion is converted into a linear, oscillating motion, but the oscillating motion is generated directly by the linear drive. It is understood that for the drive device and auxiliary drive not the same drive forms must be selected.
  • the drive device may be designed as a rotary drive and the auxiliary drive as a linear drive or the auxiliary drive as a rotary drive and the drive device as a linear drive.
