Definitions

  • the invention has for its object to provide a simply constructed honing tool with which on the whole upper surface of a hole wall, a uniform plateau structure can be generated.
  • a plurality of honing rings are preferably arranged next to one another in the axial direction of the tool body, the honing rings being at the same distance from one another, for example.
  • Each honing ring is self-tightening and slotted, so that it lies against the wall of the workpiece bore with a uniform surface pressure. It favors a good adaptation to the shape of the cylinder wall.
  • the honing tool 1 (FIGS. 1, 3) has a tool body 2 which is essentially symmetrical to the longitudinal axis 3 of the tool and which is provided at one end with an axial pin extension 4 of smaller diameter with lateral pin projections 5.
  • the pin extension 4 is inserted with the pin projections 5 in a bayonet-like manner into a correspondingly designed drive rod 6, which is indicated by dash-dotted lines.
  • the drive rod 6 is driven by a honing drive, not shown.
  • a cylinder wall 8 of a workpiece bore 7, which can be designed, for example, as a blind bore, is machined.
  • the cylindrical tool body 2 has in its circumference coaxial to the tool longitudinal axis 3 annular grooves 9, in which annular working elements 10, namely honing rings, are held.
  • the honing rings 10 are fitted into the ring grooves with axially narrow running play.
  • six ring grooves 9 are provided with honing rings 10, which are arranged in succession on the tool body 2 at a distance in the axial direction.
  • the distance between the last honing ring 10 and the lower free end 11 of the tool body 2 is kept very small, so that the machining of the cylinder wall 8 can take place up to the undercut at the bottom of the bore.
  • the distances between adjacent honing rings 10 can be the same and are preferably greater than the distance between the lower honing ring 10 and the free end 11.
  • Each honing ring 10 is self-tightening and slotted; a honing ring has the shape of an open ring spring with a rectangular cross-section.
  • the honing rings 10 have a e.g. abrasive coating 12 made of bonded diamond grain. It may be advantageous to provide one or more honing rings 10 with bristles 27 partially or entirely instead of with an abrasive coating 12, as shown in FIGS. 2a and 2b. In order to achieve an increased coolant flow to the machining surface, a coolant bore 28 in the honing ring 10 is advantageous.
  • the honing rings are present after the honing tool 1 has been inserted into the workpiece bore 7 certain and evenly acting surface pressure on the cylinder wall 8 (Fig. 1).
  • the system is achieved by the elasticity and shape of the honing rings 10, which are held on the tool body 2 like piston rings and run in the bore 7.
  • each honing ring 10 forms a joint 13, which is provided with a recess.
  • a pin 14 engages in the recess in the groove base of the ring groove 9 of the tool body 2 carrying this honing ring 10, as a result of which each honing ring 10 is held on the tool body 2 in a rotationally secured manner.
  • the rotation lock of each honing ring 10 is circumferentially offset from the rotation locks of the other honing rings.
  • the honing tool 1 is preferably provided with an internal coolant supply for flushing and cooling the work surfaces.
  • a recess is formed, which forms a circumferential ring channel 15.
  • a radial bore 16 leads from each ring channel 15 to a common blind bore 18.
  • This runs axially from the upper end face 17 of the tool body 2 and has at its open end on the end face 17 a nipple 19 which is connected to a hose line 20.
  • This hose line 20 is connected in a known manner, for example via a ring distributor, to a coolant pressure source 29, not shown, which supplies the bores 16 and 18 and the ring channel 15 with coolant or pressure medium via a hydraulic control device 30 (FIG. 3).
  • the hydraulic control device 30 is controlled by an electronic control 31, preferably an NC control unit. Via the integrated NC control unit 31 and the control unit 30 sets the hydraulic pressure in the annular chambers 15, as a result of which the contact pressure of the honing rings 10 can be regulated.
  • the coolant passes through the hose line 20, the blind hole 18 and the bores 16 into the annular channel 15 in order to flow out from there through the fitting gap between the honing ring 10 and the annular groove 9 onto the surface to be machined.
  • the abrasion is washed away from the processing surface.
  • the coolant simultaneously exerts a hydraulic pressure against the inner ring surface 21 of each honing ring 10, as a result of which each honing ring 10 is pressed against the cylinder wall 9 of the workpiece bore 7.
  • a targeted infeed of the honing rings 10 can be carried out in a simple manner via the coolant supply to the honing tool 1.
  • the surface pressure with which the honing rings 10 work can be predetermined or specifically changed during processing. If such a hydraulically acting infeed of the honing rings is provided, honing rings 10 without self-tensioning can also be used.
  • a honing cylinder 22 is expediently assigned to the honing tool 1, which cylinder is provided directly above the inlet mouth of the workpiece bore 7.
  • the catch cylinder 22 has a bore 23 aligned with the workpiece bore 7 and consisting of a cylindrical section 24, at its end 26 facing away from the workpiece, that is to say towards the top, is a conically widening section 25.
  • the section 24 has approximately the nominal size of the workpiece bore 7, while the conical section has a largest diameter which is larger than the outer diameter of the relaxed honing rings 10.
  • the honing tool 1 is lowered from an upper end position in the direction of the workpiece bore 7, the tool body first entering the catch cylinder 22.
  • the honing rings 10 are compressed radially elastically via the conical section 25 of the bore 23 to approximately the desired dimension of the workpiece bore 7 and are thus preloaded.
  • the honing tool 1 is aligned and guided to the workpiece axis 3. In such a precisely guided manner, the honing tool 1 moves into the pre-machined workpiece bore 7, the diameter of which is equal to or a few thousandths of a millimeter smaller than that of the cylindrical section 24 of the catching cylinder 22.
  • the honing tool moves completely out of the workpiece bore 7, but preferably only to a position in which the lower tool edge has just left the workpiece bore.
  • the length of the cylindrical section 24 of the bore 23 of the catch cylinder 22 can be chosen so that in this tool position (shown in dash-dotted lines in the drawing) all honing rings 10 lie within the section 24. In this way, the honing rings remain pre-tensioned even when changing workpieces and rapid return to a next workpiece is guaranteed.
