Definitions

  • the invention relates to a method for finish machining of peripheral surfaces of wave-shaped workpieces, wherein the workpiece to be machined is rotationally driven in a clamping around the clamped shaft axis, and wherein the rotating about the shaft axis workpiece by means of an endless, continuously driven abrasive belt is machined circumferentially.
  • the invention is based on the object, a method for finishing From peripheral surfaces of wavy workpieces specify with the one high surface quality is achievable and at the same time a flexible workpiece machining allows.
  • the object is achieved in that the abrasive belt the to be machined peripheral surface of the workpiece during machining partially wraps around and in one by the wrap angle given area rests flat on the workpiece and that the Loop angle changed during machining of the workpiece becomes.
  • the looping of the workpiece ensures a large contact surface with a uniform surface pressure between the sanding belt and the workpiece.
  • a high surface quality can be achieved.
  • the editing of shafts with axial depressions as for example be found in gear shafts, splines or serrations, be performed with different wrap angles.
  • the same peripheral surface of the workpiece is successively different Strapping angles of the sanding belt processed. So can for example, the surface of the cylindrical enveloping circle of a toothed shaft first be processed with a small wrap angle. In one second step is then a rounding of the edges at the edges of the Recesses by machining the workpiece surface with a large Wrap angle. Overall, by the variation of the wrap angle during workpiece machining a high flexibility of Achieved workpiece machining.
  • the abrasive belt on a tool carrier over a Clamping device as well as over two deflections, which has a working area limit, guided and the workpiece is for workpiece machining through a feed movement of the tool carrier and / or the workpiece clamping with a freely stretched sanding belt section between the Deflections brought into contact.
  • the wrap angle can hereby by changing the feed path of workpiece carrier or workpiece clamping and an adapted change in the length of the abrasive belt section to be changed.
  • the abrasive belt with a belt loop through a arranged in the circulation path of the sanding belt Band store guided and the length of the sanding belt section in Workspace controlled by tape storage. This allows one Change of the wrap angle during workpiece machining within a large area.
  • the wrap angle can also be through a relative adjustment of the deflections to each other can be changed.
  • the wrap angle can be in an angular range between a few Angular degrees and 270 ° can be changed, taking many applications preferably a wrap angle of more than 180 ° is set.
  • the invention teaches that the sanding belt in the area the workpiece surface of an endless, parallel to the grinding belt tensioned Supporting band is supported.
  • the Supporting band may be made of metal or else of an elastomeric material consist.
  • the support band via a separate clamping device guided and driven continuously as well as the grinding belt.
  • a separate or a common drive of sanding belt and Support band possible.
  • both bands move rectified at the same speed, so that in the contact area of abrasive belt and Support band virtually no relative movement between the two bands is present.
  • Fig. 1a shows a device for finish machining peripheral surfaces on undulating workpieces.
  • the device has a tool carrier 1, an endless sanding belt 2 for processing a about its axis of rotation A. rotating workpiece 3, an arranged on the tool carrier 1 sanding belt drive 4, which the abrasive belt 2 during a workpiece machining continuously drives, and a tensioning device 5 for the sanding belt 2 on.
  • the tool carrier 1 has a machining head 6 with two to each other spaced Bandumlenkept 7, a working area L of the Limit machining head 6.
  • the band deflections 7 are as pulleys educated.
  • the abrasive belt 2 is guided over the pulleys 7 and runs in the working area L on the peripheral surface of the workpiece to be machined 3 over.
  • the machining head 6 encompasses the work to be processed Circumferential surface of the workpiece 3 bifurcated so that in the work area L free-tensioning abrasive belt 2, the workpiece 3 partially wraps around and in a given by the wrap angle ⁇ area on the surface Workpiece abuts.
  • the workpiece 3 shown in Fig. 1a is a stepped shaft formed whose peripheral surfaces successively with a different Wrap angle ⁇ , ⁇ 'are processed.
  • a different wrap angle ⁇ or ⁇ ' which is flexible on the machining of the respective workpiece surfaces is agreed.
  • the wrap angle ⁇ or ⁇ ' is changed the Zustellweges of the workpiece carrier 1 and an adapted thereto Length of the grinding belt section 8 changed.
  • the abrasive belt 2 is hereby with a belt loop 9 by a in the circulation path of the sanding belt arranged band memory 10 out.
  • the length of the sanding belt section 8 in the working area L is controlled by means of the strip memory 10 (see FIG. 1a and 1b).
  • the sanding belt 2 in the area of the workpiece surface of an endless, parallel to the sanding belt 2 tensioned support belt 11 supported.
  • the support band 11 is preferably made Metal. It is guided over a separate clamping device 12 and as well the grinding belt 2 driven continuously.
  • the bands 2, 11 are moving rectified at the same speed, so that in the area of the contact surface between support belt 11 and sanding belt 2 practically no relative movement between the two bands 2, 11 is present. This will be a optimal relief of the sanding belt 2 achieved.
  • Figs. 2a and 2b show a surface processing of a toothed shaft 3 with in Axial direction A extending recesses 13.
  • a processing of the surface of the cylindrical enveloping circle 14 of the toothed shaft 3 at a small Wrap angle ⁇ is then carried out in a second processing step a Finish machining with large wrap angle ⁇ '(see Fig. 2b).
  • the Fig. 1a to 2b show that a change in the wrap angle flexible workpiece machining is possible.
  • the device is the wrapping angle ⁇ , ⁇ 'by a Relative adjustment of the pulleys 7 changed each other.
  • the machining head 6 has for this purpose pivotable fork arms 16, on which the pulleys 7 are arranged. With this device can also be Adjust wrapping angle of more than 180 °, as shown in FIG. 2b directly can be seen. In the device shown in Figs. 2a and 2b assumes the tensioning device 5 of the abrasive belt 2 at the same time the function a tape storage.
