Definitions

  • the invention relates to a method according to the preamble of claim 1 and an apparatus for performing the method.
  • Known methods of this type often show in practice a deterioration in the surface quality of the bore in the area in which a reversal of the direction of the stroke movement of the honing tool occurs. If one considers the preferred application of the invention, namely the production of cylinder bores, for example in engine cylinder blocks, the lifting movement is reversed when the honing tool is positioned both in the region of the end on the cylinder head side and in the region of the end of the cylinder block on the crankshaft side.
  • this solution requires that the honing tool can be inserted into the cylinder bore from the crankshaft side, but this is not possible with a large number of engine blocks because of the crankshaft bearing webs.
  • the known solution is not applicable in most cases.
  • the invention has for its object to provide a method of the type mentioned and an apparatus for performing the method by which the described disadvantage, namely influencing the surface quality of a bore by reversing the movement of a honing tool, is avoided.
  • the honing tool 5 executes an opposite stroke movement between the reversal points UT and OT (FIG. 1), which limit the size of the stroke.
  • the honing stones 9 (FIG. 2) of the honing tool are pressed against the wall 10 of the cylinder bore of a cylinder to be honed or the like with a certain force (pressing force).
  • the speed of the stroke movement is essentially constant between the reversals of the stroke, as the longer, straight sections of line 1 in the path-time diagram show.
  • the cutting force interruption of the honing stones according to the invention is achieved during the reversal of the stroke by a brief reset of the delivery system or the delivery device triggered by the stroke control.
  • the entire infeed system is prestressed against the infeed direction, as a result of which a particularly rapid interruption of the cutting force is achieved, as is also the case with the approximately rectangular shape of the Force characteristic curve 2 (FIG. 1) can be seen over time.
  • a honing device is shown schematically in FIG.
  • the cylinder bore 3 of an engine cylinder block 4 is machined by a honing tool 5 which is rotatably driven in a known manner and which executes a lifting movement H in the direction of the bore axis.
  • the Hontechnikzeu g 5 is articulated for this purpose via a connecting rod 6 with a honing spindle 7, which is part of a known honing machine, not shown, and can be moved up and down by a hydraulic lifting drive, namely a piston-cylinder arrangement 8.
  • the honing spindle 7 is also driven in a known manner by a rotary drive (not shown) about its longitudinal axis.
  • the honing tool 5 carries honing stones 9 which can be advanced radially outwards by a hydraulically actuated delivery device and can be pressed against the bore wall 10 of a cylinder bore 3.
  • the hydraulic actuation of the advancing device consists of a piston-cylinder assembly 11 whose piston rod 12 a through the honing spindle 7, the terminal Stan and g e 6 through the honing tool 5 leading multi-part feed rod 13 to the upper side of the feeding cone presses 14 of the honing tool.
  • the force of a strong spring 15 presses on the underside of the feed cone in the opposite direction and causes the feed system to be mechanically preloaded.
  • the hydraulic cylinder 11 is fed via lines 16, 17 from a hydraulic control unit 18 which is connected to a pressure medium source 19.
  • a 3-way valve 21 interposed, via which the upper cylinder chamber 20 can be connected directly to a return line 22 to the pressure medium container 28.
  • the 3-way valve 21 is connected via a control line 24 to an electrical stroke control device 25, which is mechanically connected to the stroke movement of the honing spindle 7, e.g. B. via a chain drive 26, coupled encoder 27 controls the stroke reversal.
  • the stroke control device 25 also outputs a control signal 24 to the directional control valve 21 for each stroke reversal.
  • the directional control valve 21 switches from the switching position 21a, in which the upper cylinder chamber 20 of the piston-cylinder arrangement 11 is fed by the hydraulic control unit 18 via the line 16 for the purpose of hydraulically actuating the delivery device, to the switching position 21b and remains in this position, as long as the control signal 24 is present.
  • the directional control valve 21 switches back to the switching position 21a and the line 20 is immediately refilled via the line 16 until the preset pressure is reached and the honing stones 9 press and cut against the bore wall 10 again with the appropriate force .
  • the start, duration and sequence of the control signal 24 is controlled in advance according to the invention by known electrical means of reversing the stroke so that, taking into account the existing mechanical and hydraulic delay times, the actual cutting force interruption of the honing stones 9 coincides with the beginning of the duration and sequence of the reversal of the stroke, as from the diagram (Fig. 1) is clearly visible.
  • the control system is preferably designed so that the beginning of the reduction in cutting force (point C of line 2 in FIG. 1) takes place in good time so that when the stroke reversal begins (point A or B of line 1 in FIG. 1) the preset is already set reduced cutting force F O is fully reached and is maintained until the end of the stroke reversal (point A 'or B').
  • the method according to the invention of at least reducing, preferably interrupting, the cutting force of the honing stones during the stroke reversal can be used for a workpiece during the entire honing period.
  • the method is preferably only used during the finishing machining. It can also be quite sufficient and advantageous to use the method during at least one, preferably several, reversals of stroke before the finished dimension is reached.
  • the method according to the invention is not limited to the hydraulic actuation of the delivery device described, but can be used in a suitable form for all known actuations for the delivery of the honing stones.
  • the cutting force reduction according to the invention can be achieved during the reversal of the stroke by a brief reversal of the direction of rotation triggered by the stroke control.
