Definitions

  • the invention relates to a machine according to the preamble of claim 1, preferably a honing machine or a drill.
  • FIG. 1 shows FIG. 1 in a spatial representation such a machined bore surface with a local formation or extension 11 and a local constriction 22.
  • This shape is the desired shape that is to be generated by the machining and then under load in the operating state to a exactly cylindrical bore deformed.
  • Such contingent contours deviating from the cylindrical shape are defined as inverted deviations from a cylindrical ideal shape, and z. As determined by finite element calculations or experimentally.
  • a method for producing such deviating from the cylindrical shape bore surfaces is for example from EP 1 321 229 A1 and the DE 4 007 121 A known.
  • JP 2000-291487A a honing tool with piezoelectric feed elements between the tool body and the honing stones (see. Fig. 6 and 7 , Reference numeral 22, as well as the sections [35 and 36] of the description).
  • FIG. 2 Referenced This shows a cross section through such a machined bore surface with a formation 11, which is defined by a change in shape ds within an angle dphi.
  • cylinder distortions with Fourier coefficients up to the 8th order must be able to be produced.
  • the speed of the tool should be as high as possible.
  • This requires a delivery dynamics, which can bring about the desired radial adjustment of the cutting means (eg a honing stone or a drill bit) correspondingly fast.
  • the radial delivery speeds are to be defined, which result from the required cutting agent-related cutting speed.
  • the object underlying the invention is therefore to provide a machine for producing non-cylindrical bore surfaces, which is simpler in construction and thus less expensive than the known machines and has an improved delivery dynamics.
  • the device for fine delivery in this case preferably the linear drive, is therefore not, as in the prior art, separately installed for each tool in the tool unit, but is only once to be provided on the machine side, in the tool receiving unit to be arranged there, connected to the various tool units can be, which must contain the actual processing tools and the deflection means for the delivery, but no longer the - relatively expensive - means for fine delivery.
  • None of the above publications shows a tool which is integrated by a machine-side tool holder, which forms an independent assembly of the machine, with the dynamic and integrated into the highly dynamic preferably linearly operating fine-duty drives, which temporarily the Zustellierien preferably several cutting means over several axially parallel Can cause Zustollstangen independently.
  • the tools described in the prior publications work with dynamic fine feeds within the tool with the smallest possible distance to the cutting means. They therefore only a small height and thus only a small delivery path is available. This makes it possible at such a location only to install means for fine delivery of small size and therefore with a relatively small delivery path.
  • one or more axially parallel acting linear drives for independent delivery of processing tools or cutting means (honing stones or drill bits) may be provided.
  • the linear drives, z. B. are designed as piezoelectric linear actuators are activated by an electric drive and generate an axial movement of a plunger with a certain force and speed on the Feed rod for the radial delivery of the cutting means of the machining tools acts.
  • the time to expand and retrieve a cutting medium is approx 10 ms.
  • the invention thus provides to constructively separate the tool unit and the tool holder with the linear drive and to associate the linear drive for the dynamic feed (fine feed) of the tool holder unit and thus of the machine or of an assembly that is independent of the interchangeable tool unit.
  • the tool unit is interchangeably arranged.
  • the tool unit only contains exclusively components for deflecting the machine-generated lifting movements in the feed movements for the processing tools and possibly the independent delivery movements for the guide rails, and the processing tools and possibly the guide rails themselves.
  • the feed rods are coaxial to the plunger or rams of the linear drives of the tool holder unit.
  • the plungers exert an axis-parallel force to the center on the aligned arranged Zustellstangen.
  • the feed force is transmitted to the radially displaceable processing tools.
  • the end faces are designed so that no normal-acting Shear forces are transferable.
  • wedge surfaces are worked, which deflect the axial movement in a radial feed movement.
  • tool receiving unit and tool unit can be produced inverted functional forms. Due to the dynamic fine feed of the machining tools, the desired desired shape can be achieved at high cutting speeds and small deformation segments with a large radial deformation with a high accuracy of a few micrometers.
  • the application of the cutting means with a coarse feed improves the dynamic delivery behavior, since the fine feed should work only in the area of local shape changes. Since the tool holder unit is structurally separated from the tool unit by the fine feed integrated in it, it is only necessary to arrange simple mechanically operated tools without their own feed drives in the tool unit. The tool unit can be exchanged for different machining tasks.
  • cooling lubricant has only direct contact with the tool, but not the tool receiving unit in which the means for fine delivery are arranged.
  • the linear drives are thus protected against the harmful influence of aggressive liquids.
  • the first embodiment according to the Figures 3 . 4a and 4b shows as part of a honing machine a tool receiving unit 1 for fine delivery. It has axially parallel direct-acting linear drives 1-06, which can be arranged all around (see also FIG. 5a ), of which in FIG. 3 only one is shown.
  • the tool unit 2 is interchangeably arranged on the tool-holder unit 1, the tool unit, ie the honing tool 2-05 provided with the cutting-medium covering 2-06, as well as the actual machining tool shown radially opposite to support the honing stone or the honing stone serving guide rail 2-04 or guide rails, and the associated Zustollstangen 1-03 (for the honing stone) and 2-02 (for the guide bar).
  • the tool unit 2 rests with its end face 2-09 on the end face 1-02 of the tool receiving unit. Both are interconnected by suitable means 1-16, for example screws.
  • the tool receiving unit 2 is simple. It can be easily and simply replaced without the tool holder unit 1, in which the axially parallel linear direct-acting means for fine delivery, namely the linear drive 1-06, are arranged to replace. When using a - expensive - piezoelectric linear delivery, this means a significant cost reduction.
  • the tool receiving unit 1 and the tool unit 2 abut each other with the end faces 1-02 and 2-09 and are easily detachable from each other.
  • the means 1-16 for this purpose are familiar in the art and therefore only hinted at.
  • the tool receiving unit 1 is located in the housing 1-01, which is connected at its upper end to the machine spindle 5. On the machine side, as is customary in honing, rotational movement, stroke movement and feed movement are forwarded to the tool receiving unit 1.
  • the delivery takes place in two modes via the infeed bar 1-09 for the guide bar 2-04 and the infeed tube 1-10 for the coarse feed of the honing stone 2-05.
  • the feed rod 1-09 is guided in the feed tube 1-10.
  • the feed tube 1-10 is connected to the carrier 1-13. Both, the delivery rod 1-09 and the infeed tube 1-10 are independent from each other. Both are for delivery axially - independently - by the control of honing or fine boring machine on which the machine spindle 5 is arranged, moved down.
  • the lower end of the feed bar 1-10 is connected to the upper flange 1-14 of the carrier 1-13.
  • linear drive 1-06 is arranged between the two flanges 1-14 of the carrier 1-13 serving for fine delivery of the honing stone 2-05 in the axial direction. It is moved from the bottom of the upper of the two flanges 1-14 down and actuated as an actuator the plunger 1-05.
  • the linear drive 1-06 is supplied by the electrical lines 1-07 with drive power and control signals. The supply of energy and control signals takes place via slip rings 1-08.
  • Non-contact inductive telemetric transmission systems can also be used.
  • the linear direct drive 1-06 operates e.g. piezoelectric with a stroke of up to 250 ⁇ m. These piezoelectric actuators are designed with a high level of centrifugal force. Also electromagnetic drives according to the principle of the plunger coil or the magnetostriction, electro-rheological or magneto-rheological actuators are possible.
  • the fine delivery means are formed by at least one linear actuator 1-06 (as shown).
  • linear actuator 1-06 as shown.
  • FIG. 5a to order the axis of the system between the flanges 1-14 further linear drives, so that each honing stone can be assigned a separate linear drive.
  • the housing 1-01 has a sealing air hole 1-11 through which a (otherwise generated) low pressure in the housing held and thus the penetration of liquid is prevented by leaks existing outside.
  • the linear drive 1-06 is, as already mentioned, provided at its lower end with a plunger 1-05 as an actuator whose linear motion is transmitted to the Zustollstange 1-03. In this way, the fine feed effected by the linear drive 1-06 is superimposed on the coarse feed predetermined by the feed bar 1-10 on the machine side.
  • the installation of linear direct drives 1-06 is free of lateral forces.
  • the play and lateral force-free power transmissions 1-04 are only symbolically represents as a ball and can be designed as joints as a flat or curved sliding surfaces or otherwise. You must transmit train and pressure without play and also have rotational degrees of freedom, so that the Zustellstange 1-03, which rests with its wedge-shaped feed surface 1-031 at its lower end to the also wedge-shaped infeed 1-031 the honing stone 2-05, in full-surface Plant can align to this. So you have u. U. can tilt slightly on the power transmission 1-04 from the plunger 1-05. They can only do this if the power transmission 1-04 does not transmit any lateral forces. Similarly, a compensation of a small axial offset between plunger 1-05 and Zustellstange 1-03 is possible.
  • a linear drive which is formed by a piezoelectric element, can move the feed bar down with great force. To reset the linear drive 1-06 only a smaller force available. The provision is therefore supported by the return spring 2-07 or even completely applied. You can also provide two linear actuators, one of which serves for delivery, the other to the provision.
  • the feed rod 2-02 provided with two cone-shaped infeed surfaces, on which the feed rod 1-09 acts from above.
  • the conical feed surfaces 2-021 and 2-022 cooperate with wedge-shaped feed surfaces on the support bar 2-03, where immediately thereafter a guide rail 2-04 is arranged radially, so that in this way the axial movement of the feed rod 1-09 is converted (deflected) into a radial movement of the guide rail (s).
  • a plurality of, for example four guide rails 2-04 can be arranged, between which four Zustollstangen 1-03 can be arranged along the circumference.
  • the linear drive 1-06 (or the liner drives) in the tool receiving unit 1 is located in a straight extension coaxial with the axis of the feed rod 1-03 (or infeed bars).
  • the wedge-shaped feed surface 1-031 At the end of the feed rod 1-03 is the wedge-shaped feed surface 1-031.
  • the honing stone 2-05 is located with the also wedge-shaped feed surface 2-051.
  • a Schneidkarbelag 2-06 is attached.
  • an axial fine delivery is thus effected on the honing stone 2-05 in addition to the rough delivery effected via the infeed tube 1-10.
  • Both feed movements are superimposed on the Zustollstange 1-03 effective and are implemented in the tool unit 2 in a radial feed movement of the Schneidkarbelages 2-06 to the bore surface 4-01 of a workpiece 4 or deflected (see the arrow).
  • the return spring 2-07 supports the play and lateral force-free power transmission 1-04 in the infeed between Linear drive 1-06 and infeed bar 1-03 at a relief (recovery) of the infeed line.
  • the feed rod 1-03 may also be made of a material of lower density, so that the movement of the linear drive can be transferred even more safely without delay due to a low mass inertia.
  • the return spring 2-07 is to be interpreted so that when relieving the honing stone with the spring force an upward acceleration is achieved, which is at least as large as the upward acceleration of the plunger 2-05, so that an axial positive engagement between the feed rod and plunger is ensured.
  • the feed rod 2-02 is designed so that it forms an angle with the inclined surface 1-31 of the feed rod 1-03, which lies outside the range of a self-locking.
  • the feed rod 1-09 is moved axially downwards on the machine side. It strikes the infeed bar 2-02, by which the guide rails 2-04 are applied against the bore surface 4-01.
  • the infeed tube 1-10 moves the carrier 1-13 of the fine feed means 1-12 axially downwards over the infeed bars 1-03 and thus presses the cutting medium covering 2-06 of the honing stones 2-05 against the bore surface 4-01 of the Workpiece 4.
  • the linear drive 1-06 is driven along the circumference of the bore, ie as a function of the angle dphi and in dependence on the vertical position of the bore.
  • Each honing stone in each position is associated with a change in shape to be achieved at this point.
  • a honing stone can also be mounted on a support strip with several wedge surfaces, as shown by the example of the guide rail 2-04 and their arrangement on the support bar 2-03.
  • Integrated dimensional, layer and shape measuring devices determine the quality either in process or post process in a separate measuring stroke (see also the force sensor 130 in FIG. 7 and 9 ).
  • FIG. 4a shows the operation of the linear drive 1-06 at a delivery force F within a molding 11.
  • the delivery force F has, as in the diagram in FIG. 4a shown above, always, that is independent of the delivery path s, a constant value. For each overrun within this deformation segment, therefore, the currently present formation 11 'is extended by a likewise constant amount ds.
  • FIG. 4b Another mode of operation of the linear drive 1-06 is in FIG. 4b shown.
  • a corresponding application of power is controlled in such a way that the delivery force F decreases with increasing delivery travel s (see the diagram), so that a relatively large formation 11 'is produced at the beginning of the processing at each overpass.
  • the radial Feed path ds As the number of passes over the area of the molding increases, the radial Feed path ds and therefore also the radial material removal ds smaller.
  • the embodiment according to FIG. 5 is different from that FIG. 3 by an improved guidance of the tool receiving unit 1 in the housing 1-01. This is ensured by the fact that the linear drive 1-06 is applied directly to the upper flange 1-14 of the support 1-13 and thereby, that the power transmission from the plunger 1-05 of the linear drive 1-06 on the Zustollstange 1-03 via a friction - and wear-resistant carbide plate 1-17 takes place.
  • the stroke of the coarse adjustment by means of the Zustellrohres 1-10 is denoted by 1-15.
  • the stroke of the fine adjustment is determined by the linear drive 1-06.
  • the two flanges 1-14 of the carrier 1-13 are formed relatively thick and with their outer dimensions so matched to the cylindrical inner surface 1-18 of the housing 1-01 that the carrier 1-13 in the housing 1-01 in its up and off movement is performed safely and without play. This makes the guided surface more stable.
  • the inner surface 1-18 is processed accordingly as tribologically stressed guide surface.
  • the flanges are 1-14 housed in the housing 1-03 against rotation.
  • they have grooves 1-19, in which as a rotation each feather key 1-20 (or a pin) protrudes radially, so that although a longitudinal movement of the flanges 1-14, but not a rotational movement is possible.
  • This arrangement thus represents an anti-rotation device for the carrier 1-13 in the housing 1-01.
  • FIG. 5a can be seen in the embodiment according to FIG. 5 . 5a-5c along the circumference (circle line K) four linear actuators 1-06 provided. These are, as well as for the linear drive 1-06 in FIG. 5 shown at the bottom of the upper flange 1-14 of the support 1-13.
  • the at the bottom 1-0 ram 1-05 are designed to be as short as possible so that any bending moments that might affect the linear actuator are minimized.
  • the tungsten carbide plate 1-17 ensures high wear resistance even with permanent pulse operation.
  • the end face of the feed rod 1-03 is designed as a dome, so that only one point contact takes place ( See also the comments in the description of the embodiment according to FIG. 7 ).
  • the linear actuators 1-06 can be force-controlled via a force measuring sensor, regulated by a strain gauge or operated in unregulated operation (the feed travel is proportional to the applied voltage).
  • the Zustellstange which was provided in the embodiments described above with the reference numeral 1-03, now formed by two Zustellstangen sections 1-30 and 1-31, which are formed separately from each other and via a compression spring 1-32 are in operative connection with each other ,
  • the linear drive 1-06 is active as a power transmission and not directly as an actuating means.
  • the delivery tube 1-10 is as in FIG. 5 educated. It moves down and pushes the linear actuators 1-06 down over the underside of the upper flange 1-14 and thus acts on the extension rod section 1-30 on the compression spring 1-32 on the infeed bar sections 1-31.
  • Characterized the honing stones 2-05 are pressed against the cylindrical inner surface of a bore of the force of the compression spring 1-32, as is particularly appropriate when smoothing a pre-machined mold.
  • the embodiment according to FIG. 7 provides appropriate measures to counter forces that arise when activating the linear drive 1-06 by pressing the honing stones 2-05 to the inner surface to be machined 4-01 a hole in the workpiece 4 and approximately in the embodiment according to FIG. 5 tends to push the infeed tube 1-10 upwards. This is done by a locking device.
  • the locking device is formed by the fact that the delivery of the honing stones 2-05 no longer by a directly from the machine operated Zustellrohr (like the infeed tube 1-10 after FIG. 3 . 5 and 6 ), but by a feed motor 111, which is arranged on a fixed housing 112 in the machine.

  • the feed nut 116 is internally provided with a trapezoidal thread 118, which is in engagement with the trapezoidal thread 119 on the outside of a spindle nut 120.

  • the feed tube 128 now acts - with the interposition of a force measuring sensor 130 - on the upper flange 1-14 of the carrier 113.
  • the flanges 1-14 are secured in the housing 1-03 by groove-key connections 131 against rotation.
  • the force measuring sensor 130 is used for readjusting the coarse adjustment, which is required with progressive removal by the fine feed.
