Definitions

  • the invention relates to a method for the conification of a cylindrical bore with a honing tool and a
  • a honing process is known with the help of the cylinder bore of an internal combustion engine receives a bottle shape.
  • a bottle shape while a form is referred to, in which the cylinder bore has two cylindrical portions which have a different diameter. The smaller diameter portion is provided in the area of the cylinder head, while the larger diameter portion is provided in the crankshaft area. Between these areas is a
  • the invention is based on the object to provide a honing process, which is the cost-effective and
  • the invention has for its object to provide a trained and equipped honing machine.
  • the method should allow a variety of user specified cylinder bore geometries accurately and
  • the geometries predefined by the user can be, for example, a truncated cone, a bottle shape or a generatrix of the "cylinder bore" of an internal combustion engine that can be predetermined by a polynomial of the nth order.
  • a honing tool is used, which has measuring devices which it
  • the honing stones have a length which is less than one third of the length of the bore to be machined. The smaller the honing stone length, the more
  • the short-wave can be the desired shape course, since with increasing strip length, the wavelengths of the desired shape, which are smaller than the honing stone length, are mechanically filtered out.
  • the measuring devices are usually arranged between the honing stones, so that where the material removal takes place and the bore diameter is detected.
  • the method according to the invention comprises the steps:
  • Perfect measurement means that during the honing process, the diameter of the hole is recorded continuously, as well as with high temporal and spatial resolution. As a result, the actual shape of the hole being processed is already available during honing in real time for controlling the honing process.
  • Manipulated variable of the control loop according to the invention is the stroke OP - UP of the honing tool.
  • the stroke of the honing tool is from a top turning point OP and a bottom
  • the inventive method comprises the steps according to claim 1. More specifically, these steps are explained in the
  • Reversal points OP n , UP n no longer being processed. In this way, it is ensured that only one or more regions of the bore are further processed, in which the actual diameter D ACT (y) is still smaller than the desired diameter DSO LL (y) desired there.
  • the reduction of the stroke can be done in several ways.
  • a control technology very easy relaisierbare
  • the stroke H n is always reduced by a predetermined amount DeltaH to one
  • the amount of DeltaH is usually chosen as a function of the total length of the hole to be honed. Also, the desired generatrix may affect the amount of DeltaH.
  • the hub H n + i is further reduced if n + i, UP n + i of the actual diameter D is at a further reversal point OP (n + i) of the last honed bore portion is equal to the nominal diameter D So ii UPn + i of the bore at this reversal point is OP n + i, UP n + i.
  • Interface then forms the new reversal point OP, UP of the honing tool.
  • the bore is generally machined over the entire length, so that the inventive method emanating from a cylindrical bore.
  • working bore can be used as a mathematical function, e.g. are given as n-th order polynomial as a function of the Y-axis (longitudinal axis of the bore).
  • n-th order polynomial as a function of the Y-axis (longitudinal axis of the bore).

  • Honing the invention bore the hole over the entire length L conical.
  • the generatrix of the conically honed bore is designated by 1 in FIG.
  • the same reference numerals for the same components apply to all figures
  • the largest diameter D Max is at the lower end of the bore.
  • the example with the number 5 is intended to make it clear that rotationally symmetrical bores can also be produced whose largest diameter lies neither at the top nor at the bottom end of the bore.
  • the largest diameter D MAX is in this embodiment between the upper and the lower end of the bore.
  • the production according to the invention is a non-cylindrical one
  • the generatrix of the bore is provided with the reference numeral 1.
  • the bore has at its upper end a cylindrical portion and at its lower end another cylindrical
  • the diameter in the region of the upper portion b is smaller than the diameter D So ii in the lower section c.
  • the starting point of the process according to the invention is a
  • Diameter D is , o is used.
  • the hole is honed over the entire length of the hole. The turning points of the
  • Honing tool or its honing stones are denoted by OPi and UPi (see Figure 2 a).
  • the method according to the invention provides for reducing the stroke of the honing tool so that the region b is no longer machined.
  • Permant spre also takes a permanent Hubverlagerung to smallest path changes, thereby creating a continuous, stepless shape curve.
  • the respective path change is limited only by the resolution of the travel sensor for the lifting movement, which, however, is much smaller than the local slope of the desired shape curve.
  • the subsequent smoothing which takes place over the entire length of the bore, the previously developed form is machined to the desired final roughness profile.
  • the "stages" shown in FIGS. 2c and 2d are greatly exaggerated
  • FIG. 3 illustrates a first variant of the reduction of the stroke according to the invention. This variant is referred to as the "default constant DeltaH for determining DeltaX".
  • the honing tool or the honing stones belonging to the honing tool 5 are once in the upper
  • the stroke of the honing stones corresponds to the distance OPl and UP when the bore is honed over its entire length.
  • An air measuring nozzle which belongs to the honing tool has been provided in Figures 3 and 4 with the reference numeral 7.
  • the amount DeltaH can be entered by the operator of the honing machine as a parameter in the control.
  • Turnaround point OP2 results from the fact that the previous upper reversal point OP1 is shifted by the amount DeltaH in the direction of the lower turnaround point UP.
  • the second setpoint diameter D So ii, 2 is equal to the nominal diameter of the bore at the reversal point OP2.
  • the amount of DeltaX is not constant, but depends on the slope of the generatrix in the upper turning point OPl and the new upper turning point OP2. Because the surface line of the bore in the machine control - for example, as a polynomial or as a table of values - is behind, can be at each reversal point OP, UP the associated nominal diameter in
  • the reduction of the stroke is more or less large, depending on how much the surface line in the area between the current upper reversal point OP n and the new upper reversal point OP n + 1 changes.
  • FIGS. 5 a to d and FIGS. 2 a to d have many similarities. The principle will be explained with reference to FIGS. 2 a to d; in the figures 5a to d of erfindungsgenzeße algorithm with the associated

  • the desired target shape is designated 36.
  • thin-walled portion 34 is radially expanded and the desired desired shape according to the line 36 is produced by the method according to the invention, then the bore springs back radially after the end of honing and there is an actual shape according to the line 38 in Figure 6b ,
  • Sollform 40 is.
  • the corrected nominal shape is the shape which the
  • Cylinder bore must accept during honing, so that they have the desired desired shape 36 after the end of the honing and without radial expansion.
  • the corrected desired shape is obtained by adding to the desired shape 36 (especially in the region of the thin-walled portion 34) the radial expansion.
  • the corrected nominal shape has the reference numeral 42 in FIG. 6c
  • the corrected nominal shape 42 compensates for these locally different radial deformations
  • the corrected nominal shape 42 can be determined empirically or by calculation. In the case of an empirical determination, it is possible to change iteratively to the corrected desired shape on the basis of the respectively achieved results, starting from the desired shape, by setting the desired shape in small numbers at a plurality of interpolation points
  • Steps are corrected until the actual shape (see 38 in Fig. 6c) in the relaxed state of the cylinder bore of the desired shape (see 36 in Fig. 6c) corresponds.
