Definitions

  • the invention relates to a method for finishing surfaces, a smoothing tool suited for the method and a workpiece.
  • Another problem consists in the fact that increased wear has been observed especially with bush-less forged connecting rods. Applicant stated that this increased wear has to be traced back to segregations in the cast blank. Such segregations (black cores) are decompositions of the melt during the casting operation. These areas have a higher hardness than the regular structure of the workpiece. If from such a casting blank a connecting rod is manufactured by forging, the segregations will occur especially in the central circumferential areas of the large and the small connecting rod eyes so that the bearing combination is subjected to wear in this area.
  • the object underlying the invention is to provide a method and a tool by which the surface quality of such surfaces is improved with simple efforts in terms of devices. Moreover, a workpiece having an improved surface quality and wear resistance is to be provided.
  • the method by the combination of features of a method for finishing surfaces, a smoothing tool as well as a workpiece.
  • the method according to the invention and the smoothing tool according to the invention can be used with particularly great success in finishing a connecting rod eye.
  • the shaft of the smoothing tool is preferably clamped in a radially feedable infeed head.
  • the infeed head is a diaphragm tilting head.
  • smoothing member preferably a natural diamond or a correspondingly hard material is formed.
  • a diamond ball or a diamond ball segment is formed.
  • the radius of a smoothing surface of the smoothing member in a preferred embodiment of the invention is within the range of from approx. 2 to 6 mm.
  • the smoothing tool is guided approximately along the same track of motion as that of the previously used machining tool.
  • the smoothing tool is preferably pressed against the surface at a predetermined surface pressure or a defined bias. This is achieved by the fact that the surface pressure of the smoothing tool or the biasing force of the smoothing tool to the surface is kept within a predetermined tolerance range.
  • substantially lower roughness depths than by conventional methods can be achieved.
  • the roughness depth obtained in preliminary tests was less than 1/1000 mm. It is confirmed by an appropriate process control of the pressing force that the diameter generation has taken place rotation-symmetrically for instance at a share of smoothing of 5 ⁇ m.
  • the desired constant pressing force can be obtained, for instance, due to the centrifugal force acting upon the smoothing member and is adjustable by the speed of the smoothing tool.
  • recesses are formed in the surface to be treated; they can be in the form of a circumferential groove, circumferentially spiral-shaped or a cross-shaped or else can be slots formed in sections.
  • the smoothing tool it is advantageous in some cases when the smoothing tool is disengaged in the area of said recesses in order to avoid stress concentrations and thus damage of the workpiece and/or the smoothing tool.
  • Such tool can be a multi-purpose tool having a small ball for introducing the trough and a large ball for smoothing the diameter.
  • the dimensional stability of the surface to be machined can be further improved, when the pre-machining tool is first adjusted to the theoretical adjusting dimension and subsequently the pre-machining, for instance fine boring, is performed by means of controlling or adjusting the tool cutting edge, until the center of any other value within the tolerance range is reached.
  • this value is picked up as zero dimension in the machine and is transferred to a measuring station—a so-called master—and is fixed.
  • zero measure can be picked up from the master and transferred to the tool in the machine. This transfer can be performed by the machine control or directly by adjustment in the tool cutting edge (infeed tool).
  • the smoothing tool is checked after smoothing whether the smoothing tool is in position. In this way it can be determined, for instance, whether the smoothing member is damaged or is still existing at all.
  • the bias mentioned in the beginning is adjusted so that also the deformation (flattening) of the smoothing tool during smoothing can be compensated.
  • the smoothing tool is a multi-purpose tool having at least one pre-machining cutting edge.
  • the pre-machining cutting edge is preferably arranged approximately diametrically with respect to the smoothing member so that optionally the smoothing tool or the pre-machining cutting edge can be engaged by a swivel movement.
  • the present application suggests for improving the wear behavior to form a circumferential groove especially in forged parts in the central portion of the circumferential walls of bearing bores/recesses—for instance the large and small connecting rod eyes.
  • Said circumferential groove is designed such that the segregations are partly abraded and thus are no longer located in the main supporting area of the bearing bore so that surprisingly the wear resistance can be substantially improved vis-à-vis conventional solutions.

  • such diaphragm tilting head 22 has a fork 24 adjustable in axial direction including a fork groove 26 extending obliquely with respect to the longitudinal axis into which a pinion 28 of a tool head 30 immerses.
  • Said tool head 30 is operatively connected to a diaphragm 32 such that, when the fork groove 26 is displaced, the tool head 30 is tilted and thus the smoothing tool 4 is deflected—as represented in FIG. 6 —in radial direction and performs a radial infeed or reset motion.
  • the tool head 30 is arranged, according to FIG. 7 , centrally between two webs 34 , 36 forming a swivel axis.
  • the smoothing surface 14 of the smoothing member 8 can be brought into a predetermined position relative to the surface to be machined. It is preferred in the method according to the invention when the smoothing surface 14 is pre-stressed by 10 ⁇ m vis-à-vis the surface to be machined. That is to say, the smoothing surface 14 is pre-stressed in radial direction by 10 ⁇ m into the workpiece vis-à-vis the surface to be machined and thus defines the smoothing plane.
  • the portion receiving the smoothing member 8 can be elastic. In the embodiment shown in FIG. 8 this is done by a parallel link 38 which is cut clear out of the tool shaft 6 by eroding, for instance. This shall be illustrated hereinafter by way of FIG. 9 showing an enlarged representation of the smoothing tool 4 from FIG. 8 .

  • Said elastomer member 54 is supported at the left-hand leg 43 of the parallel link 38 by a first end portion via a mounting element 56 and at the second leg 42 of the parallel link 38 by its second end portion.
  • the elastomer body 54 serves as a damping element and for trimming the stiffness of the smoothing tool 4 .
  • an oil damper is used instead of the elastomer member 54 .
  • the pre-machining and the smoothing are carried out for instance at two stations.
  • the pre-machining is preferably performed by fine-boring by a fine-hole drill head preferably adjustable in radial direction.
  • Said fine-hole drill head is initially preset according to the theoretical setting at an appropriate measuring device, for instance a tool presetting device.
  • the fine-boring is carried out, wherein the machining is performed by means of machine control or adjustment of the tool cutting edge, until the middle of the tolerance range or another predetermined value within the tolerance range is obtained.
  • This actual dimension is then picked up in the machine as zero dimension and said zero dimension is transferred to a measuring device, a so-called master, and is fixed.
  • said zero dimension can be directly picked up by the master and transferred in the machine by means of machine tool control or adjustment of the cutting edge (radial tool) to the fine-boring tool.
  • This course of action ensures that fine-boring is performed with maximum precision and reproducibility so that a component geometry which meets even maximum requirements and has a predetermined minimum roughness depth (less than 1 ⁇ m) is brought about by the subsequent smoothing.
  • the smoothing member 8 preferably the diamond ball is inserted in a radially adjustable infeed tool head.
  • the control is designed so that the pressing force or the surface pressure of the smoothing member 8 applied to the surface to be machined can be controlled during machining so that it remains within a predetermined tolerance range and thus constantly a particular bias (approx. 10 ⁇ m) is effective.
  • This bias is adapted to compensate also for small undesired ovals from fine-boring.
  • the radially adjustable infeed head permits to machine also surfaces having recesses—for instance for forming lubricating slots etc. It is preferred to disengage the smoothing member in the area of said lubricating slots by adjusting the infeed head so that after passing said recess the smoothing member is not exposed to impact stress, because it is engaged again only after having passed said recess.
  • a measuring device After performing the smoothing operation it is checked by a measuring device whether the smoothing member 8 is still in position and whether there is possibly wear which can then be appropriately compensated.
  • a respective measurement of wear is also carried out during pre-machining (fine-boring), wherein the tool is measured after each machining of a workpiece and possibly existing wear is stored and compensated by a station-oriented wear compensation (offset correction).
  • offset correction can be made using a sliding mean value, wherein for instance during a tool change a measuring unit rejection free of primary processing times is performed with up-to-date reading and possible offset correction.
  • FIG. 10 illustrates an embodiment of a smoothing tool 4 in the form of a multi-purpose tool 58 having a pre-machining cutting edge 60 which is practically responsible for fine-boring, wherein in a subsequent step the smoothing member 8 can be engaged with its ball segment by swiveling the tool 4 .
  • FIG. 11 showing a side view of the multi-purpose tool 58 from FIG. 10 , it has turned out to be especially advantageous when the pre-machining cutting edge 60 is disposed approximately diametrically with respect to the smoothing member 8 so that optionally the smoothing member 8 or the pre-machining cutting edge 60 can be engaged by a swivel motion.
  • FIGS. 12 and 13 show the multi-purpose tool 58 engaged with the pre-machining cutting edge 60 and engaged with the smoothing member 8 , respectively.
  • FIG. 12 a radially feedable infeed head is shown into which the multi-purpose tool 58 can be inserted.

According to FIG. 14 , the smoothing member 8 starts penetrating the surface of the component from a biasing force of approx. 40 N. At a biasing force of approx. 75 N for instance a penetration depth of 50 ⁇ m is reached.
  • an excellent surface quality allowing for a roughness RZ of 0.8 can be obtained by the smoothing method according to the invention—such roughness depths practically cannot be attained by fine-boring.
  • FIG. 16 shows a concrete measurement of the roughness depth by way of a curve 64 , wherein the roughness after fine-boring is shown on the right and amounts to approx. 2.5 to 4 ⁇ m.
  • a roughness depth shown on the left of less than 1 ⁇ m, for instance of 0.7 ⁇ m, can be obtained.
  • the connecting rod eyes 2 manufactured in this way (cf. FIG. 1 ) have an excellent quality and have proven themselves in tool-life tests so that the use of conventional bearing bushes is no longer required. It has turned out that the roundness vis-à-vis fine-bored contours can be further improved by the smoothing method according to the invention. Almost any contours, for instance round recesses, elliptic recesses (ellipsis approx. 10 ⁇ m) or contours which are trumpet-shaped in longitudinal direction can be formed by the tool according to the invention.
  • the method and the smoothing tool 4 are not restricted to the use in connecting rod eyes 2 but can also be used for other surfaces having a high surface quality.
  • the method according to the invention and the smoothing tool 4 can also be employed in machining cylinder bores, wherein the prescribed lubrication slots (spiral-shaped, diamond pattern . . . ) can be formed in the circumferential walls.
  • the method according to the invention and the smoothing tool 4 can be used as an alternative of honing which requires considerable efforts in terms of machine tools and control.
  • the invention is especially suited also for use with workpieces in which segregations occur in the area of the circumferential walls of the bearing recesses.
  • a circumferential groove is introduced into said center portion of the circumferential walls.
  • Said groove can have a width of one or more millimeters, for instance about 3 mm, in the case of a connecting rod, the depth merely amounting to a fraction of the width. So the wear behavior of the workpiece can be improved already with grooves having a depth of between 1 ⁇ m and 5 ⁇ m. I.e.
  • the width of the groove and the depth of the groove are designed, according to the invention, at a ratio of more than 100:1, preferably more than 1000:1.
  • the groove can be formed by precision-turning or else according to the method as set forth by the invention by smoothing. In the latter case, the groove can be initially pre-machined by precision-turning and then be finished by smoothing. On principle, it is also possible to form the groove by smoothing only.
  • the method according to the invention can also be used for oval bearing recesses (connecting rod eyes) or for a cross-section deviating from the circular shape, because practically any shape of recess can be tracked by the infeed head.
  • the principal advantage of a circumferential groove machined by smoothing resides in the fact that a clean oil passage is formed in which a continuous oil film is formed without cut-off so that the wear behavior of the workpiece or the bush-less connecting rod is further improved. Due to the small depth of the groove, it is also referred to as micro-groove.
  • the invention relates to a method and a smoothing tool for finishing surfaces as well as a workpiece that is machined by smoothing.
  • the surface that is to be machined is smoothed by a shaping process with the aid of a convex smoothing tool.
