Description
1 1
[0001] Uppfinningen avser en anordning far finishbearbetning av ett sarskilt ringformat arbetsstycke, med en barare for forbindning med en finishverktygshallare for hallande av ett finishverktyg, och med en drivanordning far alstring av en linjar oscillationsrarelse 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 farfarande for 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 rarelse, vid vilken finishverktyget och den arbetsstycksyta som 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 method" process 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 on an oscillating surface, in which the finishing 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 krakta arbetsstycksytor anvands sá kallade "linjarsvangare", vilka uppvisar en drivanordning, vilken tjanar till att forflytta ett medelst en finishverktygshallare till ett barare fast finishverktyg i en linjar, alltsa "ratlinjig", oscillationsrorelse. &Mane linjarsvangare är kande exempelvis genom sakandens verktygsmaskin "Race 715". For machining profiled workpiece surfaces, so-called "line benders" are used, which have a drive device, which serves to move a means of a finishing tool holder by means of a finisher tool holder into a bare fixed finishing tool in a line, i.e. "steering line", oscillating motion. & Mane liners are known, for example, through the plaintiff's machine tool "Race 715".
[0004] Det har visat sig Onskvart att kunna slutbearbeta saval mycket sma som aven mycket stora arbetsstycken med samma anordning. Dessutom är det onskvart att kunna anvanda samma anordning far finishbearbetning av olika arbetsstycksgeometrier. Slutligen är det efterstravansvart med sá korta bearbetningstider som mojligt. Onskvart has been shown to be able to finish machining very small as well as very large workpieces with the same 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 är ett andarnal med fareliggande uppfinning att astadkomma en anordning for finishbearbetning, vilken lampar sig far effektiv finishbearbetning av arbetsstycken med fran varandra starkt avvikande matt och/eller geometrier. Based on this, it is an object of the present invention to provide a device for finishing, which lamps 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 fin ishverktygsupptagning far upptagning av ett finishverktyg och en tillsatsdrivanordning for alstring av en linjar oscillationsrarelse hos 2 finishverktygsupptagningen, och genom en farbindningsanordning fOr farbindning av oscillationsenheten med bararen. According to the invention, this is solved with an oscillation unit, which has a fine ice tool pick-up for picking up a finishing tool and an auxiliary drive device for generating a linear oscillation motion of 2 the finishing tool pick-up, and by a color binding device for color bonding the oscillation unit to the bar.
[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 foljd av en medelst drivanordningen alstrad oscillationsrarelse. Pa detta salt 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 as a result of an oscillation motion generated by the drive device. On this salt, 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 finishverktyg, farbinda bararen med en oscillationsenhet, vilken uppvisar en tillsatsdrivanordning fOr alstring av en hinjär oscillationsrorelse hos en finishverktygsupptagning for upptagning av ett finishverktyg. Oscillationsenheten uppvisar aven en egen drivenhet for alstring av en oscillationstrelse, vilken fOrskjuter finishverktygsupptagningen hos oscillationsenheten och darmed aven det dartill eller dari upptagna finishverktyget i en oscillationsrarelse. Anvandningen av denna extra oscillationsenhet har fordelen, att den under drivningen av tillsatsdrivanordningen i svangning farskjutna massan ar fOrhallandevis liten, da bararen, vilken med (huvud)drivanordningen ar farskjutbar i en oscillationsrorelse, kan Wallas stilla. It is now also possible, in addition to or especially alternatively to use the connection of a finishing tool holder for holding a finishing tool, connect the bar to an oscillation unit, which has an auxiliary drive device for generating a linear oscillation movement of a finishing tool pick-up for picking up a finishing tool. The oscillation unit also has its own drive unit for generating an oscillation beam, which displaces the finishing tool pick-up of the oscillation unit and thus also the finishing tool received there or there in an oscillation motion. 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 still Wallas.
[0009] Vid anvandning av oscillationsenheten kan alltsa ett andra matt- och/eller geometrispektrum hos arbetsstycken tackas, varvid samtidigt en reducering av den oscillerande massan uppnas, varigenom ett arbetsstycke kan bearbetas med Okad oscillationsfrekvens. When using the oscillation unit, a second mat and / or geometry spectrum of workpieces can thus be thanked, at the same time a reduction of the oscillating mass is achieved, whereby a workpiece can be machined with an increased oscillation frequency.
[00010] De inom ramen for fareliggande ansakan valda uttrycken "finishverktygshallare" och "finishverktygsupptagning" avser i princip samma eller lika delar eller komponentgrupper. Den olika benamningen tjanar bara far battre farklaring av uppfinningen. 3 The terms "finishing tool holder" and "finishing tool pickup" selected in the context of the present application refer in principle to the same or equal parts or component groups. The different names only serve to give a better explanation of the invention. 3
[00011] Far farbindning av oscillationsenheten med bararen ar en forbindningsanordning anordnad. Det ar tankbart att saval finishverktygshallaren for hallande av ett finishverktyg som aven oscillationsenheten och dess finishverktygsupptagning är fasta till Waren. If the oscillation unit is connected to the carrier, a connecting device is provided. It is conceivable that the finishing tool holder for holding a finishing tool as well as the oscillation unit and its finishing tool receptacle are fixed to the Ware.
[00012] Foretradesvis ar det arida, att farbindningsanordningen innefattar ett farbindningsavsnitt pa bararsidan, vid vilket valbart, sarskilt under hansynstagande till storleken pa det arbetsstycke som skall bearbetas, finishverktygshallaren eller oscillationsenheten (med finishverktygsupptagningen) kan fastas. Detta majliggor en alternativ anvandning pa vanligt satt av en finishverktygshallare eller pa nytt satt oscillationsenheten med dess finishverktygsupptagning. It is preferred that the lashing device comprises a lashing section on the bar side, at which optionally, 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] SarskiIt fordelaktigt är det, att redan existerande verktygsmaskiner pa enkelt satt skulle kunna stallas om, namligen i det att den redan fareliggande finishverktygshallaren avlagsnas och oscillationsenheten fasts i stallet for finishverktygshallaren. It is particularly advantageous that existing machine tools could be easily rearranged, namely in that the already dangerous finishing tool holder is removed and the oscillation unit is fixed in place of the finishing tool holder.
[00014] Far att uppna en sá stor aktionsradie som majligt has anordningen fareslas, att en forsta svangningsriktning for svangning av bararen relativt ett bararstativ ar anordnad. Harigenom kan sarskilt lutningen hos en oscillationsaxel has Waren stallas in. In order to achieve such a large radius of action as the device has been dangerously arranged, a first direction of oscillation for oscillation of the carrier relative to a bar rack is arranged. As a result, in particular, the inclination of an oscillation axis has the goods can be set.
[00015] Vidare är det faredraget, da en positioneringsanordning ar anordnad for positionering av bararen utmed till varandra vinkelratt mot positioneringsaxeln, sa att aven laget far bararens oscillationsaxel ar installbar innanfOr positioneringsplanet. Furthermore, when a positioning device is arranged for positioning the carrier along each other perpendicular to the positioning axis, it is dangerous that the layer also causes the oscillation axis of the carrier to be installable within the positioning plane.
[00016] Det är dessutom faredraget, da bararen ar utbildad i form av en barararm, varigenom en rumslig frankoppling fran (huvud-)drivanordningen och farbindningsanordningen kan astadkommas. It is also dangerous, since the carrier is formed in the form of a carrier arm, whereby a spatial disconnection from the (main) drive device and the connection device can be achieved.
[00017] En ytterligare fardelaktig paverkan pa anordningens aktionsrum ges da en installningsanordning ar anordnad far installning av langden hos barararmen. Denna installbarhet kan exempelvis uppnas genom att delar av barararmen är rarliga relativt varandra eller att barararmen best& av ett flertal med varandra forbindningsbara barararmsavsnitt, varvid installningen av langden for barararmen sker genom val av antalet och/eller langden av barararmsavsnitten. An additional beneficial 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 each other. connectable 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 dá en extra svanganordning är anordnad for svangning av oscillationsenheten relativt Waren. PA detta satt kan aven lutningen hos oscillationsrorelsen hos finishverktygsupptagningen hos oscillationsenheten stabs 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 Ware. In this way, the inclination of the oscillation motion of the finishing tool pick-up of the oscillation unit can also be stabbed.
[00019] Vid en ytterligare utforingsform av uppfinningen är sâ anordnat, att oscillationsrorelsen hos bararen är tillordnad en forsta oscillationsaxel, aft oscillationsrorelsen hos finishverktygsupptagningen hos oscillationsenheten är tillordnad en ytterligare oscillationsaxel och alt den ytterligare oscillationsaxeln toper i ett plan, vilket leper parallellt med den fOrsta oscillationsaxeln. Pa detta satt kan, i det fall sa onskas, aven tva fran varandra oberoende oscillationsrorelser Overlagras pa varandra, alltsh 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, since the oscillation movement of the finishing tool receptacle of the oscillation unit is associated with a further oscillation axis and all the additional oscillation axis is parallel to a plane which the oscillation axis. In this way, if desired, two independent oscillation movements can also be superimposed on each other, all while simultaneously using the carrier drive device and the oscillation unit's additional drive device ("overlay type").
[00020] Vidare är det fOredraget, dá en forbindningsanordning och/eller oscillationsenheten uppvisar en justeringsanordning for positionering och/eller kraftuttivande hos finishverktyget hos finishverktygshAllaren eller hos finishverktyget hos finishverktygsupptagningen i en till oscillationsrOrelsen hos finishverktyget vinkelrat riktning. Delta mojliggOr en enkel positionering av en aktiv yta hos ett finishverktyg anordnad pa finishverktygshAllaren 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 have an adjusting device for positioning and / or force application of the finishing tool of the finishing tool holder or of the finishing tool of the finishing tool socket at an angle to the oscillating movement of the finishing tool. Delta enables a simple positioning of an active surface of a finishing tool arranged on the finishing tool holder or on the finishing tool socket 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 uffOringsform av uppfinningen är en styranordning anordnad, medelst vilken linjara och/eller bagformade positionerings- och/eller oscillationsrOrelser hos ett finishverktyg är Overlagringsbara pa varandra. Härigenom kan — sarskilt genom interpolation — Onskade rorelser hos finishverktyget alstras. In a further embodiment of the invention, a control device is provided, by means of 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 by interpolation - the desired movements of the finishing tool can be generated.
[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 as shown in the drawings.

The drawings show: Fig. 1 is a side view of an embodiment of a finishing device comprising a bar; Fig. 2 is a side view corresponding to that of Fig. 1 with a connecting device mounted to the Waren; 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. 6 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. 6
[00027] Positioneringsanordningen 12 innefattar en andra slid 24, vilken styrs pa den forsta sliden 14 och är positionerbar utmed en andra positioneringsaxel medelst 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 by means of a second drive 26.
[00028] Den andra sliden 24 ar farbunden med en bararram 30, pa vilken en barare 32 i form av en barararm 34 är svangbart lagrad kring en farsta 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 farsta positioneringsaxeln 22, den andra positioneringsaxeln 28 och den forsta svangaxeln 38 Wiper faretradesvis vinkelratt mot varandra. The first positioning shaft 22, the second positioning shaft 28 and the first pivot shaft 38 rotate at right angles to each other.
[00030] Bararramen 30 fungerar Mien far upptagning av en drivanordning 40 far alstring av en linjar oscillationsrarelse hos bararen 32 utmed en farsta oscillationsaxel 42 motsvarande barararmens 34 utstrackningsriktning. The bar frame 30 functions to accommodate a drive device 40 for generating a linear oscillation motion of the bar 32 along a first oscillation axis 42 corresponding to the direction of extension of the bar arm 34.
[00031] Far alstring av denna oscillationsrorelse kan en rotationsrarelse alstras medelst exempelvis en drivmotor 44, vilken rotationsrarelse medelst en i sig kand och darfar inte narnnare farklarad excenter 46 omsatts till en linjar slagrarelse. To produce this oscillating motion, a rotational motion can be generated by means of, for example, a drive motor 44, which rotational motion by means of a per se known and need no further explained eccentric 46 is converted into a linear stroke 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, exempelvis 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 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 (jamfor Fig. 2 och 6). Farbindningsanordningen 54 uppvisar ett farbindningsavsnitt 56, vilket tjanar far forbindning med senare beskrivna delar pa bararen 34. Detta farbindningsavsnitt 56 pa bararsidan uppvisar exempelvis skruvupptagningar eller skruvar 58, mutterformade fastavsnitt 60 eller andra fastelennent, vilka tjanar for forbindning av farbindningsavsnittet 56 pa bararsidan med senare beskrivna delar. 7 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 dye bonding device 54 has a dye bonding section 56 which serves to connect to later described parts of the bar 34. This dye bonding section 56 on the bar side has, for example, screw receptacles or screws 58, nut-shaped fasteners 60 or other fasteners which serve to connect the dye bonding section 56 to the bar. parts. 7
[00034] Vid ett forsta anvandningssatt has fOrbindningsavsnittet 56 pa bararsidan fasts vid detta en finishverktygshallare 62 fOr hallande av ett finishverktyg 64. Vid finishverktyget 64 handlar det sarskilt om en finishsten. In a first use, the connecting section 56 on the bar side has a finishing tool holder 62 attached to it for holding a finishing tool 64. In the case of the finishing tool 64, it is in particular a finishing stone.
[00035] DA drivanordningen 40 är aktiv och bararen 32 fOrflyttar sig oscillerande fram och tillbaka utmed den fOrsta oscillationsaxeln 42, fOrilyttar sig aven finishverktyget 64 i motsvarande riktningar (visas pa ritningen med en dubbelpil), sa att aven arbetsytan 66 has 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 rotationssymmetriskt och drivs a sin sida roterande kring en axel motsvarande arbetsstyckets centrumaxel. Vid arbetsstycksytan 68 handlar det exempelvis om innerytan pa en lagerring. When the drive device 40 is active and the carrier 32 moves oscillating back and forth along the first oscillation axis 42, the finishing tool 64 also moves in the corresponding directions (shown in the drawing with a double arrow), so that also the working surface 66 has the finishing tool 64 moving 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 fOrsta svangningslage fOr Waren 32 med heldragna linjer, i vilket en arbetsstycksyta 68, vilken toper parallellt med arbetsstyckets 70 rotationsaxel, kan slutbearbetas. Fig. 3 shows a first pivot layer for the article 32 with solid lines, in which a workpiece surface 68, which peaks 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 has 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. This pivoting stroke enables the finishing of a workpiece surface 72 to have a workpiece 74, at which the workpiece surface 72 to be machined is inclined relative to the central axis of rotation of the workpiece 74.
[00038] Vid ett ytterligare anvandningssatt for fOrbindningsavsnittet 56 pa bararsidan är i stallet for finishverktygshallaren 62 med finishverktyget 64 (jamfor Fig. 3) en i sin helhet med hanvisningsbeteckningen 76 betecknad oscillationsenhet fast vid bararen 32 (jamfOr Fig. 4). In a further mode of use for the connecting section 56 on the bar side, instead of the finishing tool holder 62 with the finishing tool 64 (cf. Fig. 3), an oscillation unit designated in its entirety by the reference numeral 76 is fixed to the bar 32 (cf. Fig. 4).
[00039] Oscillationsenheten 76 uppvisar en tillsatsdrivanordning 78, vilket tjanar till att fOrskjuta en finishverktygsupptagning 82 och ett till finishverktygsupptagningen 82 Wallet eller dar upptaget finishverktyg 84 (foretradesvis en finishsten) i oscillerande rOrelse. Denna oscillationsrOrelse är tillordnad en ytterligare oscillationsaxel 86. Denna ytterligare oscillationsaxel 86 lOper, i ett i Fig. 4 med heldragna linjer visat lage hos oscillationsenheten 76, parallellt med den forsta oscillationsaxeln 42 8 The oscillation unit 76 has an auxiliary drive device 78, which serves to displace a finishing tool receptacle 82 and a finishing tool 84 (preferably a finish stone) accommodated to the finishing tool receptacle 82 (preferably a finishing stone). This oscillation motion is associated with an additional oscillation axis 86. This additional oscillation axis 86 operates, in a position shown in Fig. 4 in solid lines by the oscillation unit 76, parallel to the first oscillation axis 42. 8
[00040] Medelst oscillationsenheten 76 kan till rotationsaxeln hos ett arbetsstycke 88 parallella arbetsstycksytor 68 eller lutande arbetsstycksytor 72 (ej visat i Fig. 4, jamfOr Fig. 3) eller aven vinkelratt Iiipande arbetsstycksytor 92 slutbearbetas. FOr detta är det fordelaktigt, da oscillationsenheten 76 och/eller forbindningsenheten 54 innefattar en ytterligare svangningsanordning 94 (jamfOr Fig. 2 och 6), medelst vilken forbindningsanordningen 56 är svangbar gemensamt med oscillationsenheten 76 eller enbart oscillationsenheten 76 kring en ytterligare svangaxel 96.
