Definitions

  • the invention relates to a combined peeling and burnishing tool for machining cylindrical inner walls, in particular Bore walls, according to the preamble of claim 1.
  • Such tools are used in particular for fine machining Hydraulic cylinders and cylinder tubes used.
  • the elongated ones Tools include a peeling head, usually two Peeling knives and an axially behind the peeling head arranged Rolling head, with the entire tool in the process Bore is rotated.
  • a tool is for example in German Offenlegungsschrift OS 264292.
  • Such tools is common that individual parts such as the guide rails on the peeling head, the rolling cone at the burnishing head or even the rolling rollers themselves a high Wear subject. In this respect, it is to maintain the required high workpiece surface quality necessary, in periodically exchange the wear parts or set again to specified standard values.
  • the object of the invention is the set-up time Such peel and burnishing tools to reduce and a to provide a higher level of user-friendliness.
  • the tool is characterized by the fact that between peeling head and finish roll head a quick release device is arranged, that from an open to a closed operating position can be brought, wherein the peeling head in the open operating position, in particular in one piece and in the axial direction of Tool is removable. This ensures that by a few Handles access to wearing parts provided or The entire peeling head can be exchanged without much effort can.
  • the invention is based on the idea of a conventional peel and Burnishing tool for machining cylindrical inner walls, in which the burnishing tool behind the peeling head is arranged, resulting in an elongated tool, that can be broken down only with a lot of time to to get wearing parts of the entire tool, thereby modify that with simple means to be solved clutch in the form of a quick release device between the peeling tool and the burnishing tool is provided.

  • a particularly comfortable Design is characterized by the fact that the peeling head attached to the adapter device together with the coupling is so that the three parts after releasing the quick release device as a unit of the peel and invention Smoothing tool can be removed.
  • the adapter device is a radially movable Having closure means and on the take-up shaft a Groove with radial depth includes, with which the closure means for releasable axial fixation of the adapter device the recording wave interacts.
  • This groove can essentially be designed extending perpendicular to the axis, for example over a predetermined peripheral area of the take-up shaft. Of the Reason of the groove can be straight or curved be, so that in the latter a groove with predetermined radial Depth results.
  • Closure means adapted to the specific shape of the groove, to the necessary axial fixation of the adapter device effect the recording wave.
  • the adapter device also moments of this on the clutch and thus can be transferred to the peeling head is provided that the adapter device further with the take-up shaft for transmitting a torque in operative connection stands.
  • This design can for example by providing a longitudinally extending to the axis of the take-up shaft key be realized, which in corresponding grooves on the take-up shaft and engages the adapter to transmit a torque.
  • This design also has the advantage that with it the adapter device after releasing the quick release device by simply pulling it off axially from the take-up shaft can be separated.
  • the adapter device has a radial Has bore in which a closure pin movable is guided, which is directed obliquely to the receiving shaft axis Contact surface having a groove wall of the take-up shaft cooperates to form a positive connection.
  • This design allows that by the radial displacement of the locking bolt whose oblique bearing surface associated with the trained groove wall of the take-up shaft come to rest, thereby a predetermined axial fixation of the adapter relative to the take-up shaft, and an automatic axial adjustment the two parts can be achieved to each other.
