ANORDNING FOR FINISHBEARBETNING AV ETT I SYNNERHET RINGFORMIGT ARBETSSTYCKE DEVICE FOR FINISHING A PARTICULAR CIRCUIT WORK
[0001]Uppfinningen avser en anordning for finishbearbetning av ett sarskilt ringformat arbetsstycke, med en barare for forbindning med en finishverktygshallare for hallande av ett finishverktyg, och med en drivanordning for alstring av en linjar oscillationsrorelse hos bararen. The invention relates to a device for finishing a special annular workpiece, with a bar for connection to a finishing tool holder for holding a finishing tool, and with a drive device for generating a linear oscillation movement of the bar.
[0002] Den avslutande bearbetningen av ett arbetsstycke är ett aven som "superfinish" eller "finbearbetningforfarande" betecknat f6rfarande f6r ytbearbetning av ett arbetsstycke. Vid dessa forfaranden trycks ett slipverkande finishverktyg, exempelvis en finishsten eller ett finishbearbetningsband, mot den arbetsstycksyta som skall bearbetas. Darvid roterar den arbetsstycksyta som skall bearbetas. Rotationen av den arbetsstycksyta som skall bearbetas overlagras med en oscillerande rorelse, vid vilken fin ishverktyget och den arbetsstycksyta sonn skall bearbetas forflyttas relativt varandra i till rotationsaxeln parallella eller lutande riktningar. The final machining of a workpiece is also referred to as a "superfinish" or "finishing process" method for finishing a workpiece. In these processes, an abrasive finishing tool, for example a finishing stone or a finishing machining strip, is pressed against the workpiece surface to be machined. This rotates the workpiece surface to be machined. The rotation of the workpiece surface to be machined is superimposed with an oscillating motion, in which the fine ice tool and the workpiece surface to be machined are moved relative to each other in directions parallel or inclined to the axis of rotation.
[0003] For bearbetning av i profil krokta arbetsstycksytor anvands sa kallade "linjarsvangare", vilka uppvisar en drivanordning, vilken tjanar till att forflytta ett nnedelst en finishverktygshallare till ett barare fast finishverktyg i en linjar, alltsa "ratlinjig", oscillationsrorelse. Sadana linjarsvangare är kanda exempelvis genom sokandens verktygsmaskin "Race 715". For the machining of profile-curved workpiece surfaces, so-called "linear curves" are used, which have a drive device which serves to move a lower part of a finishing tool holder to a bare fixed finishing tool in a linear, i.e. "straight-line", oscillating motion. Such line sweepers are known, for example, through the applicant's machine tool "Race 715".
[0004] Det har visat sig onskvart att kunna slutbearbeta saval mycket sma som aven mycket stora arbetsstycken med sannnna anordning. Dessutonn är det onskvart att kunna anvanda samma anordning for finishbearbetning av olika arbetsstycksgeometrier. Slutligen är det efterstravansvart med sa korta bearbetningstider som mojligt. It has been found unsatisfactory to be able to finish machining very small as well as very large workpieces with a true device. In addition, it is undesirable to be able to use the same device for finishing machining of different workpiece geometries. Finally, it is post-mortem with as short processing times as possible.
[0005]Utifran detta ar ett andannal med foreliggande uppfinning att astadkonnnna en anordning for finishbearbetning, vilken lampar sig for effektiv finishbearbetning av arbetsstycken med fran varandra starkt avvikande matt och/eller geometrier. Based on this, a second object of the present invention is to provide a device for finishing, which is suitable for efficient finishing of workpieces with strongly deviating mats and / or geometries.
[0006]Enligt uppfinningen loses detta med en oscillationsenhet, vilken uppvisar en finishverktygsupptagning for upptagning av ett finishverktyg och en tillsatsdrivanordning for alstring av en linjar oscillationsrorelse hos 1 finishverktygsupptagningen, och genom en forbindningsanordning fOr fOrbindning av oscillationsenheten med bararen. According to the invention, this is solved by an oscillation unit, which has a finishing tool receptacle for receiving a finishing tool and an auxiliary drive device for generating a linear oscillation movement of the finishing tool receptacle, and by a connecting device for connecting the bar oscillation unit.
[0007]Finishbearbetningsanordningen enligt uppfinningen har fordelen, att anordningen vid vanlig anvandning av en finishverktygshallare kan anvandas for avslutande bearbetning av ett arbetsstycke. Vid denna bearbetning oscillerar bararen och darmed finishverktygshallaren och det vid finishverktygshallaren hallna finishverktyget till -160 av en medelst drivanordningen alstrad oscillationsrorelse. Pa detta satt kan genom lampligt val av matt hos bararen ett forsta storleks- och/eller mattspektrum hos arbetsstycken tackas. The finishing machining device according to the invention has the advantage that the device can be used for the final machining of a workpiece during normal use of a finishing tool holder. During this machining, the bar and thus the finishing tool holder and the finishing tool held at the finishing tool holder oscillate to -160 by an oscillation motion generated by the drive device. In this way, by appropriate choice of mat at the carrier, a first size and / or mat spectrum of workpieces can be thanked.
[0008]Det är nu aven mojligt att, i tillagg till eller sarskilt alternativt till anvand- ningen av en finishverktygshallare fOr att halla ett fin ishverktyg, fOrbinda bararen med en oscillationsenhet, vilken uppvisar en tillsatsdrivanordning for alstring av en linjar oscillationsrOrelse hos en finishverktygsupptagning for upptagning av ett fin ishverktyg. Oscillationsenheten uppvisar aven en egen drivenhet for alstring av en oscillationsrorelse, vilken forskjuter finishverktygsupptagningen hos oscillationsenheten och darmed aven det dartill eller dari upptagna finishverktyget i en oscillationsrorelse. Anvandningen av denna extra oscillationsenhet har fordelen, att den under drivningen av tillsatsdrivanordningen i svangning forskjutna massan är forhallandevis liten, da bararen, vilken med (huvud)drivanordningen är forskjutbar i en oscillationsrorelse, kan hallas stilla. It is now also possible, in addition to or especially alternatively to the use of a finishing tool holder to hold a fine ice tool, to connect the carrier to an oscillation unit, which has an auxiliary drive device for generating a linear oscillation device. picking up a fine ice tool. The oscillation unit also has its own drive unit for generating an oscillation movement, which displaces the finishing tool receiving of the oscillation unit and thus also the finishing tool received there or there in an oscillation movement. The use of this additional oscillation unit has the advantage that the mass displaced in oscillation during the operation of the auxiliary drive device is relatively small, since the carrier, which with the (main) drive device is displaceable in an oscillation movement, can be kept still.
[0009] Vid anvandning av oscillationsenheten kan alltsa ett andra matt- och/eller geometrispektrunn hos arbetsstycken tackas, varvid samtidigt en reducering av den oscillerande massan uppnas, varigenom ett arbetsstycke kan bearbetas med 6kad oscillationsfrekvens. When using the oscillation unit, a second mat and / or geometry spectrum of workpieces can thus be thanked, whereby at the same time a reduction of the oscillating mass is achieved, whereby a workpiece can be machined with 6c oscillation frequency.
[00010] De inom ramen for foreliggande ansokan valda uttrycken "finishverktygshallare" och "finishverktygsupptagning" avser i princip samma eller lika delar eller komponentgrupper. Den olika benamningen tjanar bara for battre forklaring av uppfinningen. 2 The terms "finishing tool holder" and "finishing tool pick-up" selected in the context of the present application refer in principle to the same or equal parts or component groups. The various names serve only for a better explanation of the invention. 2
[00011] For forbindning av oscillationsenheten med bararen är en forbindningsanordning anordnad. Det är tankbart att saval finishverktygshallaren for hallande av ett fin ishverktyg som aven oscillationsenheten och dess fin ishverktygsupptagning ar fasta till bararen. A connection device is provided for connecting the oscillation unit to the bar. It is conceivable that the finishing tool holder for holding a fine ice tool as well as the oscillation unit and its fine ice tool pick-up are fixed to the bar.
[00012] Foretradesvis är det anda, att fOrbindningsanordningen innefattar ett forbindningsavsnitt pa bararsidan, vid vilket valbart, sarskilt under hansynstagande till storleken pa det arbetsstycke som skall bearbetas, finishverktygshallaren eller oscillationsenheten (med finishverktygsupptagningen) kan fastas. Detta mojliggor en alternativ anvandning pa vanligt satt av en finishverktygshallare eller pa nytt satt oscillationsenheten med dess finishverktygsupptagning. Preferably, the spirit is that the connecting device comprises a connecting section on the bar side, to which selectively, especially taking into account the size of the workpiece to be machined, the finishing tool holder or the oscillation unit (with the finishing tool pickup) can be fixed. This allows an alternative use in the usual way of a finishing tool holder or re-set the oscillation unit with its finishing tool pickup.
[00013] Sarskilt fordelaktigt är det, att redan existerande verktygsmaskiner pa enkelt satt skulle kunna stallas om, namligen i det att den redan foreliggande finishverktygshallaren avlagsnas och oscillationsenheten fasts i stallet for fin ishverktygshal laren It is particularly advantageous that already existing machine tools could be easily restructured, namely in that the already existing finishing tool holder is removed and the oscillation unit is fixed in place of the fine ice tool holder.
[00014] For att uppna en sa stor aktionsradie som mOjligt hos anordningen foreslas, att en forsta svangningsriktning f6r svangning av bararen relativt ett bararstativ är anordnad. Harigenom kan sarskilt lutningen hos en oscillationsaxel hos bararen stallas in. In order to achieve as large a radius of action as possible with the device, it is proposed that a first direction of oscillation for pivoting the bar relative to a bar rack is provided. In this way, in particular, the inclination of an oscillation axis of the bar can be adjusted.
[00015] Vidare är det fOredraget, da en positioneringsanordning är anordnad fOr posit ionering av bararen utmed till varandra vinkelratt mot positioneringsaxeln, sa att aven laget fOr bararens oscillationsaxel är installbar innanfOr positioneringsplanet. Furthermore, since a positioning device is arranged for positioning the bar along each other perpendicular to the positioning axis, it is preferred that also the layer for the oscillation axis of the bar is installable within the positioning plane.
[00016] Det är dessutom fOredraget, da bararen är utbildad i form av en barararm, varigenom en rumslig frankoppling Than (huvud-)drivanordningen och fOrbindningsanordningen kan astadkommas. It is furthermore preferred, since the bar is formed in the form of a bar arm, whereby a spatial disconnection than (main) drive device and the connecting device can be provided.
[00017] En ytterligare fordelaktig paverkan pa anordningens aktionsrum ges da en installningsanordning ar anordnad fOr installning av langden has barararmen. Denna installbarhet kan exempelvis uppnas genom att delar av barararmen är rOrliga relativt varandra eller att barararmen bestar av ett flertal med varandra 3 fOrbindningsbara barararmsavsnitt, varvid installningen av langden for barararmen sker genom val av antalet och/eller langden av barararmsavsnitten. A further advantageous effect on the operating space of the device is given when an installation device is arranged for installation of the length of the bar arm. This installability can be achieved, for example, in that parts of the bar arm are movable relative to each other or that the bar arm consists of a plurality of interconnectable bar arm sections, the installation of the length of the bar arm taking place by selecting the number and / or the length of the bar arm sections.
[00018] Ett ytterligare okning av flexibiliteten av anordningens aktionsradie ges da en extra svanganordning är anordnad for svangning av oscillationsenheten relativt bararen. Pa detta satt kan aven lutningen hos oscillationsrOrelsen hos finishverktygsupptagningen hos oscillationsenheten stallas in. A further increase in the flexibility of the radius of action of the device is given when an additional pivoting device is arranged for pivoting the oscillation unit relative to the bar. In this way, the inclination of the oscillation motion of the finishing tool pick-up of the oscillation unit can also be set.
[00019] Vid en ytterligare utforingsform av uppfinningen är sa anordnat, att oscillationsrorelsen hos bararen är tillordnad en forsta oscillationsaxel, att oscillationsrorelsen hos finishverktygsupptagningen hos oscillationsenheten är tillordnad en ytterligare oscillationsaxel och att den ytterligare oscillationsaxeln lOper i ett plan, vilket lOper parallellt med den fOrsta oscillationsaxeln. Pa detta satt kan, i det fall sa onskas, aven tva fran varandra oberoende oscillationsrorelser overlagras pa varandra, alltsa under samtidig anvandning av bararens drivanordning och oscillationsenhetens tillsatsdrivanordning ("overlagringsslag"). In a further embodiment of the invention, it is arranged that the oscillation movement of the bar is associated with a first oscillation axis, that the oscillation movement of the finishing tool receptacle of the oscillation unit is associated with a further oscillation axis and that the further oscillation axis operates parallel to a plane the oscillation axis. In this way, if desired, two mutually independent oscillation movements can also be superimposed on each other, i.e. during simultaneous use of the carrier drive device and the oscillation unit's additional drive device ("overlay type").
[00020] Vidare är det fOredraget, da en forbindningsanordning och/eller oscillationsenheten uppvisar en justeringsanordning for positionering och/eller kraftutOvande hos fin ishverktyget hos fin ishverktygshallaren eller has finishverktyget hos finishverktygsupptagningen i en till oscillationsrorelsen hos finishverktyget vinkelrat riktning. Detta mojliggor en enkel positionering av en aktiv yta has ett fin ishverktyg anordnad pa fin ishverktygshallaren eller pa finishverktygsupptagningen relativt en arbetsstycksyta som skall bearbetas och/eller alstringen av en presskraft, med vilken den aktiva ytan hos finishverktyget trycks mot den arbetsstycksyta som skall bearbetas. Furthermore, it is preferred that a connecting device and / or the oscillation unit has an adjusting device for positioning and / or force application of the fine ice tool at the fine ice tool holder or has the finishing tool of the finishing tool pickup at an angle to the oscillating movement of the finishing tool. This enables a simple positioning of an active surface having a fine ice tool arranged on the fine ice tool holder or on the finishing tool receiving relative to a workpiece surface to be machined and / or the generation of a pressing force with which the active surface of the finishing tool is pressed against the workpiece surface to be machined.
[00021] Vid en ytterligare utf6ringsform av uppfinningen är en styranordning anordnad, nnedelst vilken linjara och/eller bagformade positionerings- och/eller oscillationsrorelser hos ett finishverktyg är overlagringsbara pa varandra. Flarigenom kan — sarskilt genom interpolation — onskade rorelser has fin ishverktyget alstras. 4 In a further embodiment of the invention, a control device is provided, below which linear and / or rear-shaped positioning and / or oscillation movements of a finishing tool can be superimposed on each other. In this way, especially through interpolation, the desired movements can be generated by the fine ice tool. 4
[00022] Uppfinningen avser dessutom ett system for finishbearbetning av sarskilt ringformade arbetsstycken, vilket innefattar en ovan beskriven anordning och en finishverktygshallare. Ett sadant system kan vid anvandning av drivanordningen hos bararen drivas gemensamt med finishverktygshallaren och drivas under anvandning av oscillationsenheten vid anvandning av tillsatsdrivanordningen. The invention further relates to a system for finishing machining particularly annular workpieces, which comprises a device described above and a finishing tool holder. Such a system can, when using the drive device of the bar, be operated jointly with the finishing tool holder and operated during use of the oscillation unit when using the auxiliary drive device.
[00023] Ytterligare kannetecken och fordelar hos uppfinningen framgar av den efterfOljande beskrivningen och de sasom ritningar visade fOredragna utforingsexemplen. Further features and advantages of the invention will become apparent from the following description and the preferred embodiments shown as shown in the drawings.
[00024] Pa ritningarna visar: Fig. 1 en sidovy av en utforingsform av en anordning for finishbearbetning, vilken innefattar en barare; Fig. 2 en sidovy motsvarande den i Fig.1 med en till bararen monterad forbindningsanordning; Fig. 3 en sidovy motsvarande den i Fig. 2 med en finishverktygshallare forbunden med f6rbindningsanordningen; Fig. 4 en sidovy motsvarande den i Fig. 2 med en oscillationsenhet forbunden med f6rbindningsanordningen; Fig. 5 en perspektivvy av oscillationsenheten; och Fig. 6 en perspektivvy av f6rbindningsanordningen. In the drawings: Fig. 1 shows a side view of an embodiment of a finishing device, which comprises a bar; Fig. 2 is a side view corresponding to that of Fig. 1 with a connecting device mounted to the bar; Fig. 3 is a side view corresponding to that of Fig. 2 with a finishing tool holder connected to the connecting device; Fig. 4 is a side view corresponding to that of Fig. 2 with an oscillation unit connected to the connecting device; Fig. 5 is a perspective view of the oscillation unit; and Fig. 6 is a perspective view of the connecting device.
[00025] En utforingsform av en anordning for finishbearbetning visas i Fig. 1 till 4 och betecknas dar i sin helhet med hanvisningsbeteckningen 10. An embodiment of a finishing device is shown in Figs. 1 to 4 and is designated there in its entirety by the male reference numeral 10.
[00026] Anordningen 10 innefattar en positioneringsanordning 12 med en forsta slid 14, vilken styrs pa en forsta slidstyrning 16 och 18 och är positionerbar utmed en forsta positioneringsaxel 22 medelst en fOrsta positioneringsdrivning 20. The device 10 comprises a positioning device 12 with a first slide 14, which is guided on a first slide guide 16 and 18 and is positionable along a first positioning shaft 22 by means of a first positioning drive 20.
[00027] Positioneringsanordningen 12 innefattar en andra slid 24, vilken styrs pa den forsta sliden 14 och är positionerbar utmed en andra positioneringsaxel nnedelst en andra drivning 26. The positioning device 12 comprises a second slide 24, which is guided on the first slide 14 and is positionable along a second positioning shaft below a second drive 26.
[00028] Den andra sliden 24 är forbunden med en bararram 30, pa vilken en barare 32 i form av en barararm 34 är svangbart lagrad kring en fOrsta svangaxel 38 medelst en forsta svanganordning 36. The second slide 24 is connected to a bar frame 30, on which a bar 32 in the form of a bar arm 34 is pivotally mounted around a first pivot shaft 38 by means of a first pivot device 36.
[00029] Den fOrsta positioneringsaxeln 22, den andra positioneringsaxeln 28 och den forsta svangaxeln 38 loper foretradesvis vinkelratt mot varandra. The first positioning shaft 22, the second positioning shaft 28 and the first pivot shaft 38 preferably run perpendicular to each other.
[00030] Bararrannen 30 fungerar aven for upptagning av en drivanordning 40 for alstring av en linjar oscillationsrorelse hos bararen 32 utmed en forsta oscillationsaxel 42 motsvarande barararmens 34 utstrackningsriktning. The bar rim 30 also functions to receive a drive device 40 for generating a linear oscillation movement of the bar 32 along a first oscillation axis 42 corresponding to the direction of extension of the bar arm 34.
[00031] For alstring av denna oscillationsrorelse kan en rotationsrorelse alstras nnedelst exennpelvis en drivnnotor 44, vilken rotationsrorelse nnedelst en i sig kand och darfor inte narmare forklarad excenter 46 omsatts till en linjar slagrorelse. To generate this oscillating motion, a rotational motion can be generated, for example, a drive notch 44, which rotational motion below a per se known and therefore not further explained eccentric 46 is converted into a linear beating motion.
[00032] Barararmen 34 uppvisar en fran drivanordningen 40 vand fri ande 48. Avstandet mellan den fria anden 48 och svangaxeln 38, matt i en riktning parallell med den andra positioneringsaxeln 28, är foretradesvis installbart, exennpelvis genom val av antalet och/eller langden av olika bararavsnitt 50 hos barararmen 34. The bar arm 34 has a free spirit 48 from the drive device 40. The distance between the free spirit 48 and the pivot shaft 38, matt in a direction parallel to the second positioning shaft 28, is preferably installable, for example by selecting the number and / or the length of different bar sections 50 of the bar arm 34.
[00033] Vid den fria anden 48 av barararmen 34 finns en fastyta 52, vilken tjanar for att fasta en forbindningsanordning 54 (jannfor Fig. 2 och 6). Forbindningsanordningen 54 uppvisar ett forbindningsavsnitt 56, vilket tjanar for forbindning med senare beskrivna delar pa bararen 34. Detta forbindningsavsnitt 56 pa bararsidan uppvisar exempelvis skruvupptagningar eller skruvar 58, mutterformade fastavsnitt 60 eller andra fastelement, vilka tjanar for forbindning av forbindningsavsnittet 56 pa bararsidan med senare beskrivna delar. 6 At the free spirit 48 of the bar arm 34 there is a fixed surface 52, which serves to fasten a connecting device 54 (cf. Figs. 2 and 6). The connecting device 54 has a connecting section 56, which serves for connection to later described parts of the bar 34. This connecting section 56 on the bar side has, for example, screw receptacles or screws 58, nut-shaped fixed sections 60 or other fastening elements, which serve to connect the connecting section 56 on the bar side. parts. 6
[00034] Vid ett forsta anvandningssatt hos forbindningsavsnittet 56 pa bararsidan fasts vid detta en finishverktygshallare 62 f6r hallande av ett fin ishverktyg 64. Vid fin ishverktyget 64 handlar det sarskilt om en fin ishsten. In a first use of the connecting section 56 on the bar side, a finishing tool holder 62 is attached to it for holding a fine ice tool 64. The fine ice tool 64 is in particular a fine ice stone.
[00035] Da drivanordningen 40 är aktiv och bararen 32 forflyttar sig oscillerande fram och tillbaka utmed den forsta oscillationsaxeln 42, fOrflyttar sig aven finishverktyget 64 i motsvarande riktningar (visas pa ritningen med en dubbelpil), sá att aven arbetsytan 66 hos finishverktyget 64 ror sig pa motsvarande satt fram och tillbaka. Med arbetsytan 66 kan da en arbetsstycksyta 68 hos ett arbetsstycke 70 slutbearbetas. Arbetsstycket 70 är vanligtvis rotationssymnnetriskt och drivs a sin sida roterande kring en axel motsvarande arbetsstyckets centrumaxel. Vid arbetsstycksytan 68 handlar det exempelvis om innerytan pa en lagerring. As the drive device 40 is active and the carrier 32 moves oscillatingly back and forth along the first oscillation axis 42, the finishing tool 64 also moves in corresponding directions (shown in the drawing with a double arrow), so that also the working surface 66 of the finishing tool 64 moves on the corresponding sat back and forth. With the work surface 66, a workpiece surface 68 of a workpiece 70 can then be finished. The workpiece 70 is usually rotationally symmetrical and is driven in turn rotating about an axis corresponding to the center axis of the workpiece. The workpiece surface 68 is, for example, the inner surface of a bearing ring.
[00036] I Fig. 3 visas ett f6rsta svangningslage f6r bararen 32 med heldragna linjer, i vilket en arbetsstycksyta 68, vilken lOper parallellt med arbetsstyckets 70 rotationsaxel, kan slutbearbetas. Fig. 3 shows a first pivot stroke for the carrier 32 with solid lines, in which a workpiece surface 68, which runs parallel to the axis of rotation of the workpiece 70, can be finished.
[00037] Ett andra svangningslage fOr bararen 32 visas i Fig. 3 med streck-punktlinjer. Detta svangningslage mojliggor finishbearbetningen av en arbetsstycksyta 72 hos ett arbetsstycke 74, vid vilket den arbetsstycksyta 72 som skall bearbetas lutar relativt arbetsstyckets 74 centrala rotationsaxel. A second pivot stroke for the bar 32 is shown in Fig. 3 with dash-dotted lines.
