Definitions

  • a method for finish machining peripheral surfaces on wave-shaped workpieces is known from the document US 5,951,377.
  • the known method there is a point contact between the grinding belt and the workpiece during workpiece machining in a cutting plane perpendicular to the shaft axis.
  • US-B-6 220 946 discloses a method with the features described above.
  • the surface of the abrading belt assembly is made by tensioning the abrasive belt by means of a tensioner. Due to the tensile stress exerted on the sanding belt, the pressing force is used for finish machining is available, given. In order to apply a high cutting force, the use of a pressure shoe is proposed, which is applied to the outside of the sanding belt.
  • the flexibility of this prior art method is limited due to the fixed geometry of the An für tenus.
  • the invention has for its object to provide a method for finish machining of peripheral surfaces of wavy workpieces, with a high surface quality can be achieved and at the same time allows flexible workpiece machining.
  • the object is achieved by a method having the features of claim 1, in which the grinding belt is supported in the region of the workpiece surface by an endless, parallel to the sanding belt support belt, wherein the sanding belt and the support belt are rectified and moved at the same speed.
  • the looping of the workpiece ensures a large contact surface with a uniform surface pressure between the grinding belt and the workpiece.
  • a high surface quality can be achieved.
  • the support band By the support band, the tensile stress of the abrasive belt is significantly reduced and the abrasive belt is very uniform with a defined pressure force on the workpiece surface to be machined.
  • the support band may be made of metal or else of an elastomeric material.
  • the grinding belt is guided on a tool carrier via a clamping device and two deflections which limit a working area, and the workpiece is brought to the workpiece processing by a feed movement of the tool carrier and / or the workpiece clamping with a free-loaded abrasive belt section between the deflections in contact.
  • the wrap angle can be changed by changing the feed path of the workpiece carrier or workpiece clamping and an adapted thereto change the length of the grinding belt section.
  • the sanding belt is guided with a belt loop through an arranged in the circulation path of the sanding belt tape storage and controlled the length of the sanding belt section in the work area by means of the tape storage. This allows a change in the wrap angle during workpiece machining within a wide range.
  • the wrap angle can also be changed by a relative adjustment of the deflections to each other.
  • the wrap angle can be changed in an angle range between a few angular degrees and 270 °, wherein for many applications preferably a wrap angle of more than 180 ° is set.
  • the support belt is guided over a separate clamping device and driven continuously as well as the grinding belt.
  • both bands move rectified at the same speed, so that there is virtually no relative movement between the two bands in the contact area of the grinding belt and the support belt.
  • Fig. 1a shows a device for finish machining of peripheral surfaces of wavy workpieces.
  • the apparatus comprises a tool carrier 1, an endless grinding belt 2 for processing a workpiece 3 rotating about its axis of rotation A, a grinding belt drive 4 arranged on the tool carrier 1, which continuously drives the grinding belt 2 during workpiece machining, and a clamping device 5 for the grinding belt 2.
  • the tool carrier 1 has a machining head 6 with two mutually spaced band deflections 7, which limit a working area L of the machining head 6.
  • the band deflections 7 are formed as deflection rollers.
  • the grinding belt 2 is guided over the deflection rollers 7 and passes in the working area L past the peripheral surface of the workpiece 3 to be machined.
  • the machining head 6 engages around the peripheral surface of the workpiece 3 to be machined in a fork shape such that the grinding belt 2, which is freely tensioned in the working region L, partially wraps around the workpiece 3 and rests flat against the workpiece in a region predetermined by the wrap angle ⁇ .
  • the workpiece 3 shown in Fig. 1a is formed as a stepped shaft, the peripheral surfaces are processed successively with a different wrap angle ⁇ , ⁇ '.
  • a comparative consideration of Fig. 1a and 1b it can be seen that initially the smaller peripheral surface of the stepped shaft 3 is processed at a small wrap angle ⁇ , while then processing the large peripheral surface the stepped shaft 3 with a large wrap angle ⁇ 'takes place.
  • the grinding belt 2 is guided on the tool carrier 1 via the tensioning device 5 as well as on the two deflection rollers 7, which delimit the working area L.
  • the workpiece 3 is brought to workpiece machining by a feed movement of the tool carrier 1 with a free-loaded abrasive belt section 8 between the two guide rollers 7 in contact.
  • a different wrap angle ⁇ or ⁇ ' is present during the two processing steps according to FIGS. 1a and 1b, which is flexibly adapted to the processing of the respective workpiece surfaces.
  • the wrap angle ⁇ or ⁇ ' is changed by changes in the feed path of the workpiece carrier 1 and an adapted thereto length of the grinding belt section 8.
  • the abrasive belt 2 is guided here by a belt loop 9 through a belt store 10 arranged in the circulation path of the sanding belt.
  • the length of the abrasive belt section 8 in the work area L is controlled by means of the belt store 10 (see Figures 1a and 1b).
  • the grinding belt 2 is supported in the region of the workpiece surface by an endless supporting belt 11, which is tensioned parallel to the grinding belt 2.
  • the support band 11 is preferably made of metal. It is guided over a separate clamping device 12 and driven continuously as well as the grinding belt 2.
  • the bands 2, 11 move rectified at the same speed, so that there is virtually no relative movement between the two bands 2, 11 in the area of the contact surface between the support belt 11 and the sanding belt 2. As a result, an optimal discharge of the abrasive belt 2 is achieved.
  • FIGS. 1a to 2b show that a flexible workpiece machining is made possible by the change of the wrap angle.
  • the machining head 6 has for this purpose pivotable fork arms 16 on which the deflection rollers 7 are arranged. With this device, wrap angles of more than 180 ° can also be set, as can be seen directly from FIG. 2b. In the device shown in FIGS. 2a and 2b, the tensioning device 5 of the sanding belt 2 simultaneously assumes the function of a belt store.
