Definitions

  • the present invention relates to a honing tool for honing the inner surface of an opening in a workpiece according to the preamble of claim 1 and a method for honing the inner surface of an opening in a workpiece with such a honing tool.
  • the respective honing tool is inserted into the opening to be machined.
  • the honing tool can be moved into the stationary opening or the workpiece with the opening can be moved relative to the stationary honing tool in such a way that the honing tool retracts. Then it is used for honing typical movement of a rotation with superimposed up and down movement of the honing tool in the opening.
  • the workpiece or the honing tool or both can be moved so that the corresponding relative movement is present between the workpiece and the honing tool. See e.g. GB-A-562 659 .
  • honing openings in particular bores
  • these openings have generally been machined in previous work steps, a set size of the openings often not being achieved with sufficient reliability and accuracy by the previous work steps.
  • a control measurement prior to the honing is usually carried out.
  • Two honing operations are often required during honing.
  • the first honing operation can aim to correct the diameter and shape accuracy and the second honing operation smoothes the surface.
  • Honing machines usually have a separate honing station for each of these honing steps, each with its own honing tool. It is often desired or necessary to check the result of the respective honing operation at an additional re-measuring station. Carrying out these, possibly quite numerous, work steps requires complex honing machines and extensive workpiece transport within the honing machine.
  • the object of the present invention is to provide a honing tool which enables a honing machine to be operated as efficiently as possible.
  • a further object of the present invention is to provide a method with which an opening can be processed as efficiently as possible and with a short processing time.
  • the honing tool according to the invention is designed with a tool body which extends in an axial direction and which has a honing section which comprises a group of honing stones, wherein the honing tool comprises a workpiece control element for checking the size and / or position of the opening, which is located on the tool body, is arranged movably in the axial direction relative to the tool body.
  • the present workpiece control element is therefore not used to monitor the honing process but to check whether the workpiece to be machined is positioned correctly or correctly in a previous work step has been edited. This check can be carried out by means of the workpiece control element in the course of the running-in process, so that a separate preliminary check can be omitted.
  • the workpiece control element is thus designed and arranged to control the retraction process of the honing tool. By means of the workpiece control element, it is therefore possible to check during the retraction process whether it can be carried out as intended. In other words, in contrast to measuring strips, for example, which enable the honing process itself to be checked, the workpiece control element of the honing tool according to the invention has nothing to do with the actual honing process.
  • the workpiece control element enables a prior check of the alignment or the size of the bore of the workpiece to be integrated into the running-in process of the honing tool.
  • a check as to whether the workpiece or its bore has a sufficient width and / or is correctly positioned in order to be able to retract the honing tool was carried out in a separate step by means of separate measuring devices.
  • the honing tool according to the invention is in particular a honing tool for machining an opening in a gearwheel.
  • the workpiece control element can in particular serve to ensure that the opening in the workpiece has a sufficient opening width, for example that a nominal dimension was achieved in previous processing steps. This can also or additionally Serve workpiece control element to exclude a positioning or alignment error of the opening of the workpiece.
  • the honing tool can be damaged when conventional honing tools are retracted. For this reason, the opening width is usually checked for a nominal size at a preceding work station. Due to the movable mounting of the workpiece control element, the honing tool can be retracted into the opening, and if the opening width of the opening falls below the intended dimension, the workpiece control element contacts the inner surfaces of the opening, whereupon the retraction process can be aborted.
  • the movable arrangement of the workpiece control element in relation to the tool body ensures that neither the honing tool nor the workpiece are damaged.
  • the present honing tool now offers the possibility of using the workpiece control element to check for sufficient width and correct alignment of the opening when retracting, without there being any risk of damage to the bore or the honing stones Inclination of the opening can be damaged by "knocking" on the wall of the bore.

  • a relative movement between the honing tool and the workpiece is also meant in the honing process, it being possible for the honing tool and / or the workpiece to be moved.
  • the honing process includes a superposition of translational and rotational relative movement between the workpiece and the honing tool.
  • the workpiece control element is coupled to a detection device, the detection device being designed to detect a movement of the workpiece control element relative to the tool body.
  • the detection device is coupled to a control device in such a way that the control device interrupts the movement of the honing tool into the opening when the detection device detects a movement of the workpiece control element relative to the tool body.
  • the workpiece control element is also biased into an initial position and so on Tool body arranged that the workpiece control element is moved from the starting position when the workpiece control element comes into contact with the workpiece, in particular when the honing tool is retracted into the opening of the workpiece. If the workpiece control element is moved from the starting position, this can be detected and the process of moving the honing tool into the workpiece can be aborted. This reliably prevents damage to the workpiece or the honing tool.
  • the workpiece control element is resiliently arranged on the tool body. As a result, the workpiece control element is always clamped in an intended position and offers a certain resistance to movement.
  • the resilient mounting can be implemented using mechanical springs, preferably metallic springs. Mechanical springs can, for example, be designed as spiral or leaf springs. It is also conceivable that the workpiece control element is resiliently mounted via an elastic polymer material. Pneumatic or hydraulic suspension of the workpiece control element is also conceivable. A magnetic or electromagnetic suspension of the workpiece control element is also conceivable.
  • the workpiece control element has a contact section for contacting the workpiece, which expands from a workpiece-side end of the tool body along the axial direction in a radial direction.
