Definitions

  • the invention relates to a method for finishing of waves, esp. of crankshafts and camshafts, with a workpiece surface one around its Rotary axis rotating workpiece with the help of a continuously driven endless sanding belt is processed and where the sanding belt tensioned with a tensioning device and at its rear in the area of Work piece surface of an endless, in this area parallel to the sanding belt strained support band is supported.
  • a method with the features described above is from the document US 5,951,377.
  • the known method takes place between the grinding belt and the workpiece to be machined one in a cutting plane perpendicular to the axis of rotation punctiform contact.
  • the sanding belt is in the area of the workpiece surface to be machined between two pulleys led, which also stretch the support band.
  • the invention is based on the object, a method for finishing of shafts, esp. Of crankshafts and camshafts specify that a uniform and specifically tunable to the workpiece surface to be machined Finish machining possible.
  • the object is achieved in that the abrasive belt and the support band partially loop around the workpiece so that the abrasive belt flat against the circumference of the workpiece, and that the support band means a separate second clamping device is tensioned.
  • the inventive Procedure is the abrasive belt area with uniform surface pressure on the workpiece surface to be machined, wherein the contact pressure of the sanding belt by the separate tensioning device of the support band is specifically adjustable.
  • the sanding belt drive allows a targeted Matching the cutting speed to the surface to be processed. Esp. are high cutting speeds even with small workpiece diameters which for ensuring good finisher results are required, adjustable. As a result, the inventive allows Process a finish machining of workpiece surfaces, the high Meet the requirements for surface quality.
  • the support band is preferably made of a high tensile material Young's modulus, for example a metal.
  • Young's modulus for example a metal.
  • the support belt can be tensioned machine-resistant.
  • the support belt is also continuous and driven off with the same direction of movement as the grinding belt. hereby can reduce the mechanical stress on the sanding belt be used so that also abrasive belts with low tensile strength can be.
  • the speed of the support belt corresponds the speed of the sanding belt.
  • the abrasive belt can with a wrap angle of more than 90 ° flat on the machined peripheral surface of the workpiece. This allows a very uniform machining of the workpiece.
  • the invention also provides a device for carrying out the Method according to claim 8. Preferred embodiments of this device are described in claims 9 to 12.
  • Fig. 1 shows a device for finishing a shaft.
  • the Device comprises a tool carrier 1, an endless sanding belt 2 for Finish machining of a rotationally driven about its axis of rotation A.
  • Workpiece 3 a sanding belt drive 4, which the sanding belt 2 during a workpiece machining continuously drives, and a clamping device 5 for the sanding belt 2.
  • the tool carrier 1 has a machining head 6 with two mutually spaced band deflections 7, the one Limit working area L of the machining head 6.
  • the band deflections 7 are formed as pulleys.
  • the sanding belt 2 is guided over the pulleys 7 and runs in the work area L to the machining peripheral surface of the workpiece 3 over.
  • Supporting belt 8 is provided, which in the working area L of the machining head 6 is stretched parallel to the sanding belt 2 and in the work area L the Rear side of the sanding belt 2 is supported.
  • the machining head 6 surrounds the processing peripheral surface of the workpiece 3 so that the back of The support belt 8 acted upon abrasive belt 2, the workpiece 3 partially wraps around and along a peripheral portion of the processed Workpiece surface rests flat.
  • the support band 8 is by means of a separate second clamping device 9 stretched. This second tensioning device 9 allows a targeted adjustment of the exerted by the abrasive belt 2 on the workpiece 3 Surface force.
  • the mechanical stress on the abrasive belt 2 is caused by the support belt. 8 significantly reduced, so no special requirements for tensile strength of the abrasive belt 2 must be made.
  • the sanding belt drive allows a targeted adjustment of the cutting speed on the working surface. The for the achievement of good finisher results required high cutting speeds are thus even at small Workpiece diameters possible.
  • the support band 8 is in the embodiment made of metal, but may alternatively be made of an elastic material consist. The support belt 8 is together with the sanding belt 2 over the Work area L limiting pulleys 7 out and is in Embodiment of FIG.
  • the two clamping devices 5, 9, the Both bands 2.8 and the sanding belt drive 4 are common on the Workpiece carrier 1 is arranged.
  • the tensioning devices 5.9 have adjusting devices 10 for changing the tape lengths in the working area L. Of the Wrap angle ⁇ between the grinding belt 2 and the machined Workpiece surface is more than 90 ° in the embodiment. This is a very uniform workpiece machining possible.
  • the tool carrier 1 is mounted on a feed carriage 11.
  • Fig. 2 shows a further embodiment of the invention Contraption.
  • the tool holder 1 follows here the orbital motion of its axis of rotation A rotating workpiece 3, which in Fig. 2 as Crankshaft is formed.
  • Bearing shafts 12, 12 'are provided, whose shape corresponds to the workpiece 3.
  • the tool carrier 1 is on peripheral surfaces 13, 13 'of Bearing shafts 12, 12 'mounted, the surface to be machined of the workpiece 3 correspond.
  • a separate support belt drive 14 is provided, which continuously drives the support belt 8.
  • the rectified ones Belt speeds of sanding belt 2 and support belt 8 are also in this Embodiment identical.
  • the tool carrier is the first pivotally mounted about a rotation axis C, which is parallel to the rotation axis A. of the workpiece 3 is aligned and in one between the machining head 6 and the grinding belt drive 4 lying tool carrier area arranged is. Trained as a swivel arm tool carrier 1 can by an oscillating pivoting movement of the rotating workpiece surfaces of the Crankshaft 3 follow, with the contact area between abrasive belt 2 and workpiece 3 within the work area L during the orbital motion moves accordingly. Due to the simple construction and Operation, this embodiment allows a particularly cost-effective Finish machining of crankshafts and camshafts.
  • the distance of the sanding belt drive 4 of the axis of rotation C of the tool carrier 1 is set so that a substantial mass balance of the about the rotation axis C given vibrating masses. Furthermore, one is along the tool carrier 1 slidably arranged mass 15 is provided before the Beginning of processing at a specific position of the tool carrier. 1 lockable, so that the desired contact force between abrasive belt 2 and workpiece surface is ensured during processing. Also in this Embodiment, the support band 8 is also continuously with the same Direction of movement and speed as the sanding belt 2 of the Sanding belt drive 4 driven.
