Definitions
- the invention relates to a roller burnishing tool having a base body extending along a longitudinal central axis, at least one roll holder arranged radially adjustable on the base body, on which a roller burnishing roller is mounted, and an adjusting device arranged in the base body, which interacts with the roller holder in the radial direction for an adjustment of the roll holder ,
- Such a burnishing tool is used for a roller burnishing of a workpiece surface in order to obtain a defined surface structure, surface finish or surface geometry.
- the roller burnishing tool is unrolled on the workpiece surface to be machined with a predetermined contact pressure, whereby the workpiece surface to be machined undergoes a plastic deformation.
- Such a tool is used, for example, for the further processing of the inner surface of a cylinder bore or a cylinder liner of an internal combustion engine in which a thread-like micro groove structure has already been introduced to produce by a plastic deformation of the webs formed between the microgrooves undercuts and thereby one for the application To provide a coating material suitable surface texture.
- Examples of such roller burnishing tools are given in DE 20 2009 014 180 U1, DE 10 2012 207 455 A1 or WO 2012/084612 A1.
- the present invention seeks to provide a more stable rolling tool, which allows a fine adjustment of a roll holder.
- the roll holder has a holder arm, which can be deflected in a pivotable manner by the adjusting device in the radial direction.
- An adjustment of the roller burnishing in the radial direction thus no longer takes place by a rectilinear radial displacement of the roll holder, but by a pivoting movement of the holder arm of the roll holder, which means a change in position held on the roll holder roller burnishing in the radial and axial directions.
- the pressure element acting between the adjusting device and the roller holder can be kept relatively small in its cross-sectional size.
- a pressure element radially movable recess in the base body may be formed substantially smaller in terms of their extension in a direction transverse to the direction of displacement of the pressure element as a the entire roll holder receiving Recess with the result that the body is less weakened by this going to the adjusting recess. Thanks to the smaller recess, it is possible to distribute a larger number of roller holders in the circumferential direction of the roller burnishing tool.
- the storage and mounting of the pivotable support arm on the base body substantially reduced to a realized for example by a pin or bolt pivot axis on which the holder arm is pivotally mounted.
- the contact surfaces between the holder arm and the main body for example, the side walls defining a receiving pocket, where friction can occur, can be kept smaller than in the prior art discussed above.
- the rolling roller may have a convexly outwardly curved or spherical rolling surface. If the axis of rotation of the roller burnishing cylinder tilts by a pivoting movement of the holder arm of the roller holder with respect to the rotational or longitudinal central axis of the roller burnishing tool, can be maintained by the crown of the rolling surface a substantially constant Anspress- pressure, even if the contact point of the roller burnishing on the workpiece surface to be machined - relative to the rotational or longitudinal central axis of the roller burnishing tool - may slightly shift axially.
- the roller cage can by a Rotation about the cage axis under the contact pressure of the machining Align the workpiece surface in such a way that results in a full investment of the roller burnishing roller on the workpiece surface to be machined.
- an adjusting device To adjust the radial position of the roller holder relative to the adjusting device or the base body may be provided between the roller holder and the adjusting device an adjusting device.
- an adjusting device can be integrated, for example, in the pivotable support arm of the roll holder.
- the above-mentioned pressure member may be disposed between a feeder-side control slope and the adjusting device.
- the roller burnishing tool has a multiplicity of roller holders distributed with a predetermined, preferably the same, angular pitch about the axis of rotation, which roller holders are preferably synchronously adjustable by the adjusting device. Furthermore, the roll holders, viewed in the axial direction, can be arranged at the same height, whereby the forces acting on the roller burnishing tool during a burnishing process are compensated.
- the threaded spindle can be actuated from the front side of the main body.
- the operation can be done manually or machine tool controlled.
- a rotationally movable at the front end of the body, but held axially fixed actuator can be provided which is rotationally fixed, but axially movable in engagement with the threaded spindle.
- the threaded sleeve displacing screw drive allows for axial displacement, the roller holder between a controlled position, in which the rolling roller held on the roll holder is at a minimum diameter, and an extended position, in which the rolling roller held on the roll roller is at a maximum diameter, to adjust.
- the screw drive therefore allows an accurate fine adjustment of the roller holder independent of an adjustment between the controlled position and the controlled position.
- Such an adjustment of the roll holder between a stowed position in which the rolling roller held on the roll holder is at a minimum diameter, and a staggered position in which the Rollierwalze held on the roll holder is at a maximum diameter can be realized for example by the fact that the screw is connected to a piston arranged in a pressure chamber in the main body.
- the piston can be elastically, preferably resiliently, supported relative to the main body.
- the screw can have a screwed with the threaded sleeve threaded spindle.
- This threaded spindle can be connected, for example, with the above-mentioned piston, but this is not mandatory.
- the threaded spindle can be formed from a differential threaded spindle.
- the screw drive may further comprise a bushing arranged between the threaded sleeve and the piston, which is connected, for example with the aforementioned piston zug- / d jerk-tight, and the differential threaded spindle with a first threaded portion with the threaded sleeve and with a second threaded portion with be bolted to the bearing bush.
- a compression spring can be arranged between the threaded sleeve and the screw, whereby a high diameter accuracy can be achieved.

- Fig. 2 is a longitudinal sectional view of the roller burnishing tool
- Fig. 3 is an enlarged scale in section of the longitudinal sectional view of
- Fig. 1 shows in a perspective side view of a roller burnishing tool 10, which is used for example for further processing of the inner surface of a cylinder bore or a cylinder liner of an internal combustion engine, in which a thread-like extending microgroove structure is introduced, by a plastic deformation of the formed between the microgrooves Footbridges To create intersections and thereby create a suitable surface structure for the application of a coating material.
- the roller burnishing tool 10 has a main body 12 extending along a rotational or longitudinal central axis 11, which in the embodiment shown has a modular construction of a front part 12a and a rear part 12b. As shown in Fig. 1, the front part 12a and the rear part 12b are bolted together. At its rear end (on the right in FIG. 1), the roller burnishing tool 10 has a coupling shaft 13 to be connected, for example, to a machine tool spindle, which in the embodiment shown is formed from a HSK (hollow shaft cone) shaft. Alternatively, however, for example, a so-called SK (steep taper) shaft or the like may be provided.
- the roller burnishing tool 10 can be used standing or rotationally driven.
- roller holders 4 are arranged in an equidistant angular pitch in the base body 2.
- the roll holders are arranged in particular in the axial direction at the same height.
- Each roll holder 14 carries a roller burnishing roller 15 and is adjustable radially inwardly or outwardly via a central actuating device 16 to be seen in FIG. 2 in synchronism with the respective other roller holders 14.
- each roll holder 14 is individually positionally adjustable via an associated adjusting device 17 in the radial direction relative to the central adjusting device 16 or to the rotational or longitudinal central axis 1 1 of the base body 12.
- roller holders 14 are all distinguished by the same construction and the same mode of operation, so that the construction and the mode of operation of the roller holders 14 will be described in more detail below using the roller holder 4 shown in FIG. 2 as an example.
- the holder body 18 is made of a prismatic or block-shaped block, which is received in a in the direction of the rotary or longitudinal central axis 1 1 of the body 12 extending prismatic or cuboid, front and outer peripheral side receiving pocket 25 in the base body 12 , which is formed at a radial distance to the rotational or longitudinal central axis 1 1.
- the receiving pocket 25 is substantially symmetrical in cross-section (see Fig. 1).
- the roll holder 14 constructed in the manner of a bending clamp holder has the holder body 18a fixedly attached to the base body 12 via the two clamping screws and the holder arm 18b which is pivotally movable in the radial direction and which is connected to the holder body via a material joint 18d formed by a recess 18c 18a is connected.
- the material joint 18d permits elastic bending or deflection of the holder arm 18b in the radial direction about a fictitious pivot axis 18e sketched in FIG.
- the roller burnishing roller 15 is rotatably mounted in a roll cage 15a fastened to the holder arm 18b about a roller axis 15b.
- the roller cage 15a is snugly received in the pivotally movable holder arm 18b in an outer peripheral side open recess 18f and fixed to the holder arm 18b via fixing screws 15c.
- the roll axis 15b is parallel to the rotational or longitudinal center axis 1 1 of the burnishing tool 10.
- FIG. 2 shows that the holder body 18 is supported on the control surface 31 of the central actuating device 16 via the adjusting strip 17a of the adjusting device 17 integrated in the holder arm 8b and the pressure pin 26 arranged radially displaceable in the base body 12.
- the central actuating device 16 has, as shown in Fig. 2, a threaded body 28 arranged in the base body 12 and a threaded sleeve 28 axially displacing screw 29.
- the threaded sleeve 28 forms a radial adjustment of the roller holder 14 effecting actuating means. It is rotationally fixed in a central bore 29a in the base body 12, but axially displaceable and acts via a wedge gear with the roller holders 14 together.
- the threaded sleeve 28 has, as shown in FIG. 2, on its outer circumference, a number of support strips 30 corresponding to the number of roller holders 14.
- Each support strip 30 is assigned to one of the roller holders 14 and on the outside has the control surface 31 inclined relative to the rotational or longitudinal central axis 11 against which the pressure pin 26 cooperating with the roller holder 14 abuts.
- Each pressure pin 26 is arranged radially displaceably in a radially extending bore 27 in the base body 12.
- the control slope 31 forms with the end face of the pressure pin 26 an already mentioned Wedge gear, which converts an axial movement of the threaded sleeve 28 in a radial movement of the pressure pin 26.
- the rotationally fixed arrangement of the threaded sleeve 28 in the central bore 29a in the base body 12 is achieved by engaging in an axial longitudinal slot 33 on the outer circumference of the threaded sleeve 28 locking pin 34 which is releasably held in a radial stepped bore 35 in the base body 12. As shown in FIG.
- the engagement of the locking pin 34 in the longitudinal slot 33 of the threaded sleeve 28 is secured by a locking screw 36.
- the locking pin 34 has an enlarged diameter head 37 which abuts radially inwardly against a step 38 of the stepped bore 35.
- the screw 29 has, as shown in Fig. 2, substantially a threaded spindle 39 and an axial distance to the threaded sleeve 28 in the central bore 29 a arranged in the base body 12 bearing bush 40 on.
- the threaded spindle 39 is formed from a differential threaded spindle, which is screwed via a first threaded portion 39 a with an internally threaded bore of the threaded sleeve 28 and a second threaded portion 39 b with an internally threaded bore of the bearing bush 40.
- the bushing 40 is analogous to the threaded sleeve 28 in the central bore 29a in the base body 12 rotatably, but arranged axially displaceable.
- the rotationally fixed arrangement of the bearing bush 40 is achieved by a rotationally fixed connection with a piston extension 41 of a piston 42 described later, which is rotatably in a piston bore 43 in the base body 2, but arranged axially displaceable.
- a compression spring 44 is arranged, on the one hand a thread play between the external thread of the first threaded portion 39a of the threaded spindle 39 and the internal thread of the threaded sleeve 28 and on the other hand, a thread clearance between the external thread of the second threaded portion 39b of the threaded spindle 39 and the internal thread of the bearing bush 40 to reduce.
- the piston 42 is rotatably in a piston bore 43 in the base body 12, but arranged axially displaceable. It can be seen in Fig. 2 that the piston bore 43 is connected via a connecting bore 46 with the central bore 29 a.
- the step-like piston 42 has a piston extension 41, which penetrates the connecting bore 46 and in the region of the central bore 29 a rotationally and zug- / d juckfest with the bearing bush 40 is connected.
- the non-rotatable arrangement of the piston 42 in the piston bore 43 is achieved by a locking pin 47, which in an axial
- Longitudinal slot 48 engages on the outer circumference of the piston 42 and is releasably held in a radial stepped bore 49 in the base body 12.
- the engagement of the locking pin 47 in the longitudinal slot 48 of the piston 42 is secured by a locking screw 50.
- the locking pin 47 has an enlarged diameter head 51 which abuts radially inwardly against a step 52 of the stepped bore 49.
- a formed between the connecting bore 46 and the piston bore 43 step 56 forms an axial stop for the piston 42.
- the piston 42 is fluidly driven in the embodiment shown against the spring force of the compression spring 53 in Fig. 2 to the left.
- the piston 42 is received sealed in the piston bore 43.
- Via a pressure channel 61 formed in the main body 12 a fluid pressure is fed into a pressure chamber 62 of the piston bore 43 delimited by the piston 42, whereby the piston 42 is displaced to the left against the spring force of the pressure spring 53 in FIG.
- a displacement of the piston 42 causes a rectified displacement of the bearing bush 40 and thus of the screw 29 and the threaded sleeve 28th
- the adjusting device 16 at the front end of the body 12 rotatably, but axially held actuator 57 which is rotatably, but axially movable with the threaded spindle 39 into engagement.
- the actuating element 57 has a quadrangular cross section 58, which engages in a form-fitting manner in a cross-sectionally quadrangular engagement opening 59 of the threaded spindle 39.
- the actuation element As can be seen in FIG. 1, has a graduated ring 60, which makes possible a verifiable rotation of the actuation element 57 and thus of the threaded spindle 39.
- roller burnishing 15 are exactly on a predetermined nominal diameter of the roller burnishing tool 10. Only then is it possible to achieve for all roller burnishing rollers an equally high contact pressure, which is necessary for uniform printing processing of the surface to be processed. In order to meet this requirement, the roller burnishing rollers must be able to be adjusted 15 ⁇ m precisely to a specified nominal diameter. This is necessary, for example, when the roller tool 10 is recombined, or when wear necessitates readjustment of individual roller burnishing rollers 15.
- each roller holder 14 relative to the base body 12, in particular the arranged in the base body 12 central adjusting device 16, in the radial direction adjustable.
- Each Craigram 14 is associated with an individually operable adjusting device 17, via which the holder arm 14 and thus the roller mounted on the holder roller 15 relative to the base body 12, in particular the rotational or longitudinal central axis 1 1, are radially adjustable.
- the integrated in the pivotable support arm 18b of the roller holder 14 adjusting device 17 has the aforementioned Justierology 17a and two bevel screws 17e, 17f.
- the adjustment strip 17a which is essentially quadrangular in cross-section, is accommodated in a form-fitting manner with a tight clearance fit in a guide recess 18g formed in the holder arm 18b.
- the position of the adjusting bar 17a in the longitudinal direction of the holder arm 18b is determined by the two conical screws 7e, 17f, 17g in the adjustment bar 17a each press against an associated conical surface of two in the direction of displacement of the adjusting bar 17a spaced cones 17g.
- the two conical screws 17e, 17f can therefore be actuated from outside the roller burnishing tool 10 by means of a suitable tool wrench.
- inclined surface 17b is incorporated in the adjustment bar 17a obliquely applied to their direction of displacement and the rotational or longitudinal central axis 11 of the roller burnishing tool 10 inclined surface 17b is incorporated.
- Integrating the adjusting device 17 into the holder body 18 results in a compactly constructed roll holder 14, which can handle the integrated adjusting device 17 and the roller burnishing roller 15 as an exchangeable component and can be attached to the base body 12 of the roller burnishing tool 10.
- the sketched axle point rotatably mounted, which is aligned transversely to the rotational or longitudinal central axis 1 1 of the roller burnishing tool 10 and on a rotary or longitudinal central axis 11 of the roller burnishing tool 10 containing longitudinal section plane (see, for example, the plane of FIG. 2 or 3) of the roller burnishing tool 10 is vertical.
- the roller cage can align itself with the roller burnishing roller 15 under the contact pressure of the workpiece surface to be machined upon pivoting of the holder arm 18b.
- the adjusting device 17 is integrated in the roller holder 18. That does not have to be that way.
- the adjusting device 17 may instead be integrated into the main body 12. It is only crucial that the adjusting device is arranged functionally between the roll holder 8 and the base body 12.
- each roll holder 14 is formed in the manner of an elastically deformable bending beam and clamped in an associated receiving pocket on the main body of the roller burnishing tool 10 by screwing.
- each roll holder can also be designed in the manner of a two-armed pivot holder, which is arranged rocker-like in a receiving pocket on the base body.
- each pressure pin 26 is arranged radially displaceably in a radially extending bore 27 in the base body 12.
- each pressure pin 26 may be arranged to be radially displaceable in a guide bush, not shown in the figures, arranged in the base body 12.
- roller burnishing tool 10 is used for cylinder bore machining.
- the invention is not limited to this application.
- a plurality of roller holders 14 on the main body 12 of the roller burnishing tool 10 in the axial direction at the same height and at predetermined angular intervals about the rotational or longitudinal central axis 1 first of the main body 12 is arranged.
- the arrangement of the roller holder 14 at the same height in the axial direction is not mandatory.
- the roll holder 14 can also be axially offset, for example offset helically, arranged.
- the roller burnishing tool 10 may have a plurality of roller holders 14 or just one roller holder 14.
- the pressurization of the piston 42 is fluidic, in particular pneumatic or hydraulic.
- the pressurization of the piston 42 may be initiated by an electric motor or electromagnetically.
- the roller burnishing tool 10 can therefore have a hydraulically, pneumatically, electromotively or electromagnetically operating actuator which drives the piston 42.
- control surfaces 31 provided on the threaded sleeve 28 may be directly or indirectly, e.g. be arranged on the threaded sleeve 28 bars 30 may be provided. Furthermore, instead of individual control surfaces 31, the threaded sleeve 28 may have a rotationally symmetrical cone surface on which the roller holder or rollers 4 is or are supported indirectly or directly.
