Description
455 536 g En vinkelmåtanordning med en komplett stator i hâstskoform år också känd. Vid denna fastsâttes anslutningsnavet med del- ningsskivan först på den externa drivaxeln. varefter statorn sätts mot monteringsytan och förskjuts 10 15 20 25 30 35 455 536 radiellt till rätt läge. Det rätta läget bestäms antingen genom en justering radiellt och tangentiellt tills rätt signalutseende från anordningen erhålls eller genom att monteringsytan i förväg försetts med en med axeln noga koncentrisk cylinderyta mot vilken styrytor i statorn anslutes (EP 0100828). I båda dessa fall krävs en in- justering av avståndet mellan delningsskivan och sta- torns avkänningsplatta, vilket kräver omsorg och lätt ger skador i rastren. Den öppna statorformen gör också att en kåpa till mätanordningen ej kan tätas av mot an- ordningen själv. 455 536 g An angle measuring device with a complete stator in the shape of a horseshoe is also known. In this case, the connection hub with the pitch plate was first attached to the external drive shaft. after which the stator is placed against the mounting surface and displaced radially to the correct position. The correct position is determined either by an adjustment radially and tangentially until the correct signal appearance from the device is obtained or by the mounting surface being provided in advance with a cylinder surface which is carefully concentric with the shaft to which guide surfaces in the stator are connected (EP 0100828). In both these cases, an adjustment of the distance between the dividing disc and the stator sensing plate is required, which requires care and easily damages the grids. The open stator shape also means that a cover for the measuring device cannot be sealed against the device itself.
De nämnda kända vinkelmätanordningarna lider också av nackdelen att delningsskivan ej kan ges en vinkelmäs- sig orientering före monteringen. Detta krävs ofta vid den praktiska användningen, där ett på delningsskivan befintligt referensmärke skall orienteras i förhållande till den externa drivaxelns vinkelläge. Vid denna juste- ring måste delningsnavet med delningsskivan lossas från axeln och under vridning på rätt avstånd från avkän- ningsplattan justeras till och låsas i rätt läge. Denna justering är svår och känslig ett utföra och kräver där- för utbildad personal.The mentioned known angle measuring devices also suffer from the disadvantage that the dividing disc cannot be given an angular orientation before mounting. This is often required in practical use, where a reference mark present on the dividing disc must be oriented in relation to the angular position of the external drive shaft. During this adjustment, the crossover hub with the crossover disc must be detached from the shaft and, while rotating at the correct distance from the sensing plate, adjusted to and locked in the correct position. This adjustment is difficult and sensitive to perform and therefore requires trained personnel.
De kända vinkelmätanordningarna av denna typ har dessutom nackdelen att levereras som flera separata enheter, som först vid monteringen fogas samman till en" komplett vinkelmätanordning. Nackdelen består främst i att delningsskivan är mycket känslig och bräcklig, i synnerhet som den ofta görs av glas och därför vid transport och montering måste skyddas och hanteras med stor försiktighet.The known angle measuring devices of this type also have the disadvantage of being delivered as several separate units, which are only joined together during assembly into a "complete angle measuring device. The disadvantage is mainly that the dividing plate is very sensitive and fragile, especially as it is often made of glass and therefore during transport and assembly must be protected and handled with great care.
Uppfinningen har som uppgift att eliminera tidigare nämnda nackdelar hos kända utföranden av i ingressen_1 nämnda vinkelmätanordningar. Uppgiften löses genom de i patentkraven nämnda kännetecknen, som möjliggör att vinkelmätanordningen efter att vid tillverkningen ha justerats in, på ett enkelt och tillförlitligt sätt, 455 536 10 15 -bibehåller denna justering tills den monterats på den enhet där den ska användas. Den justering som krävs ligger alltså helt hos tillverkaren, som givetvis har utbildad personal och lämpliga anordningar för detta.The object of the invention is to eliminate the previously mentioned disadvantages of known embodiments of angle measuring devices mentioned in the preamble. The object is solved by the features mentioned in the claims, which enable the angle measuring device, after being adjusted in manufacture, in a simple and reliable manner, to maintain this adjustment until it is mounted on the unit where it is to be used. The adjustment required is thus entirely with the manufacturer, who of course has trained personnel and suitable devices for this.
De fördelar som speciellt uppnås med uppfinningen är att vinkelmätanordningen trots att den ej har egen lagring, kan levereras som en enhet utan krav på in- justering hos användaren och dessutom utan krav på sär- skilda centreringsanordningar och dylikt på monteringsf ytan.The advantages which are especially achieved with the invention are that the angle measuring device, although it does not have its own storage, can be delivered as a unit without requirements for adjustment by the user and also without requirements for special centering devices and the like on the mounting surface.
Fördelaktiga vidareutvecklingar och utföringsformer av uppfinningen framgår av underkraven.Advantageous further developments and embodiments of the invention appear from the subclaims.
I anslutning till bifogade ritningar beskrivs ett utföringsexempel av en vinkelmätanordning och en för- bindningsdel utfört som en optisk givare monterad på en motor. 10 15 455 536 Figurerna visar ett utföringsexempel av en vinkel- mätanordning enligt patentkraven i olika situationer.In connection with the accompanying drawings, an exemplary embodiment of an angle measuring device and a connecting part designed as an optical sensor mounted on a motor is described. 455 536 The figures show an embodiment of an angle measuring device according to the claims in different situations.
Figur 1 a och 1 b visar en vinkelmätanordning monte- rad på en motor och med förbindningsdelen lossad, dvs utseendet vid användning. Figur 1 a är ett snitt A-A från figur 1 b. Figur 1 b är ett delsnitt B-B från figur 1 a.Figures 1 a and 1 b show an angle measuring device mounted on a motor and with the connecting part loosened, ie the appearance in use. Figure 1 a is a section A-A from figure 1 b. Figure 1 b is a partial section B-B from figure 1 a.
Figur 2 a och 2 b visar två vyer av en vinkelmät- anordning monterad på en justeranordning med förbind- ningsdelens placering indikerad. Figur 2 b är ett del- snitt C-C från figur 2 a.Figures 2 a and 2 b show two views of an angle measuring device mounted on an adjusting device with the location of the connecting part indicated. Figure 2 b is a partial section C-C from figure 2 a.
Figur 3 a och 3 b visar två vyer av vinkelmätanord- ningen i den injusterade form den överförs mellan juster- anordningen och t ex motor, dvs med stator och anslut- ningsnav sammanbundna av den lösbara förbindningsdelen.Figures 3 a and 3 b show two views of the angle measuring device in the adjusted shape, it is transferred between the adjusting device and, for example, motor, ie with stator and connection hub connected by the detachable connecting part.
Figur 3 b är ett delsnitt D-D från figur 3 a. 455 536 10 15 20 25 30 35 Figur 1 visar en vinkelmätanordning 1 bestående av en delningsskiva 2 på ett anslutningsnav 3 monterat på motorns 4 axel 5 med en stoppskruv 6 och en stator 7 monterad på motorns 4 monteringsyta 8 med skruvar 9.Figure 3 b is a partial section DD from figure 3 a. 455 536 10 15 20 25 30 35 Figure 1 shows an angle measuring device 1 consisting of a dividing disc 2 on a connecting hub 3 mounted on the shaft 5 of the motor 4 with a stop screw 6 and a stator 7 mounted on the mounting surface 8 of the motor 4 with screws 9.
Statorn 7 innehåller en avkänningsenhet bestående av en belysningsenhet 10, en avkänningsplatta 11, fotoele- ment 12 och pulsformningselektronik 13 som på känt sätt avkänner delningsskivans 2 vinkeldelning. Fotoelemen- ten 12 och pulsformningselektroniken 13 är monterade på plattan 14 som i sin tur är fäst på statorns 7 under- del via skruvar och distanser.The stator 7 contains a sensing unit consisting of a lighting unit 10, a sensing plate 11, photoelements 12 and pulse shaping electronics 13 which sense the angular pitch of the dividing disc 2 in a known manner. The photo elements 12 and the pulse shaping electronics 13 are mounted on the plate 14 which in turn is attached to the lower part of the stator 7 via screws and spacers.
Ursparningen 15 i statorn 7 lämnar utrymme för uppsttkande delar från monteringsytan 8 respektive mon- teringsplanet 18 såsom centreringsflänsar. För skydd mot t ex damm täcks vinkelmätanordningen 1 av en ej visad kåpa som tätar mot en 0-ring i spåret 16.The recess 15 in the stator 7 leaves space for projecting parts from the mounting surface 8 and the mounting plane 18, respectively, such as centering flanges. For protection against eg dust, the angle measuring device 1 is covered by a cover (not shown) which seals against an O-ring in the groove 16.
Vid tillverkning av vinkelmätanordningen 1 place- ras statorn 7 på en justeranordnings 17monteringsplan 18 och justeras med justerelement 19 genom förskjutning längs monteringsplanet 18 till rätt läge radiellt och tangentiellt relativt delningsskivans 2 och anslutnings- navets 3 gemensamma centrumlinje som i sin tur samman- faller med justeranordningens 17 axel 20 centrum på vilken anslutningsnavet 3 monteras. Delningsskivan 2 på sitt anslutningsnav 3 justeras sedan till rätt av- stånd från avkänningsplattan 11 (axiell justering).In the manufacture of the angle measuring device 1, the stator 7 is placed on the mounting plane 18 of an adjusting device 17 and adjusted with adjusting element 19 by displacement along the mounting plane 18 to the correct position radially and tangentially relative to the common centerline 2 and connecting hub 3 which in turn coincide with the adjusting device. 17 shaft 20 center on which the connecting hub 3 is mounted. The dividing disc 2 on its connecting hub 3 is then adjusted to the correct distance from the sensing plate 11 (axial adjustment).
När detta gjorts och vinkelmätanordnigen 1 slut- justerats förbinds statorn 7 med anslutningsnavet 3 via förbindningsdelen 21 i sitt injusterade läge med skru- varna 22 till statorn och skruven 23 till anslutnings- navet 3. Skruvarna 22 och 23 fästs därvid i gängade hål i stator 7 respektive anslutningsnav 3. Förbind- ningsdelen 21 är utformad med en V eller U-formad del: för anslutning mot anslutningsnavet 3 cylindriska del och en plan yta för anliggning mot statorns 7 underdel och har så stora hål (eller slitsar) för skruvarna 22 10 15 20 25 30 35 2455 sas loch 23 att viss förskjutning av förbindningsdelen 21 relativt skruvarna 22 mot statorn 7 och relativt skruven 23 mot anslutningsnavet 3 medges. Genom denna frigång i hålen möjliggörs den tidigare nämnda fixe- ringen i det vid justeringen bestämda läget. Fri- gången i hålen för skruvarna 22 mot statorn 7 medger också viss vinkelmässig justering av delningsskivan 2.When this has been done and the angle measuring device 1 has been finally adjusted, the stator 7 is connected to the connecting hub 3 via the connecting part 21 in its adjusted position with the screws 22 to the stator and the screw 23 to the connecting hub 3. The screws 22 and 23 are fixed in threaded holes in stator 7 respective connecting hub 3. The connecting part 21 is formed with a V or U-shaped part: for connection to the connecting hub 3 cylindrical part and a flat surface for abutment against the lower part of the stator 7 and has such large holes (or slots) for the screws 22 10 15 2455 2455 loops 23 are said to allow some displacement of the connecting part 21 relative to the screws 22 towards the stator 7 and relative to the screw 23 towards the connecting hub 3. Due to this clearance in the holes, the previously mentioned fixation in the position determined during the adjustment is made possible. The clearance in the holes for the screws 22 against the stator 7 also allows some angular adjustment of the dividing disc 2.
Därigenom medges att vinkelmätanordningen 1 vid till- verkningen kan finjusteras in till ett förutbestämt vinkelläge relativt det vinkelläge där en referens- puls indikeras i vinkelmätanordningen 1. Grovjuste- ringen åstadkoms genom att referenspulsen på delnings- skivan 2 placeras i lämpligt läge gentemot det gängade hålet i anslutningsnavet 3 för skruven 23.This allows the angle measuring device 1 to be fine-tuned during manufacture to a predetermined angular position relative to the angular position where a reference pulse is indicated in the angle measuring device 1. The coarse adjustment is achieved by placing the reference pulse on the dividing disc 2 in a suitable position opposite the threaded hole in the connecting hub 3 for the screw 23.
För att medge större justermöjligheter och minska dess tillverkningskrav kan förbindningsdelen givetvis också vara flerdelad.In order to allow greater adjustment possibilities and reduce its manufacturing requirements, the connecting part can of course also be multi-part.
Efter slutjusteringen enligt ovan kan vinkelmät- anordningen 1 med sin förbindningsdel 21 fixerad lossas från justeringsanordningen 17 och som en enhet med väl skyddad delningsskiva 2 i justerad form överföras till t ex en motor. Hela justerförloppet görs alltså hos tillverkaren som kan leverera en helt färdigjusterad vinkeimatanoraning 1 med hjälp av den iasbara förbind- ningsdelen 21.After the final adjustment as above, the angle measuring device 1 with its connecting part 21 can be fixedly detached from the adjusting device 17 and as a unit with well-protected dividing disc 2 in adjusted form transferred to, for example, a motor. The entire adjustment process is thus carried out by the manufacturer, who can deliver a completely pre-adjusted angle gear unit 1 with the aid of the detachable connecting part 21.
Hos användaren skjuts vinkelmätanordningen 1 som en enhet sammanbunden av förbindningsdelen 21 över motorns 4 axel 5, statorn 7 förbinds med skruvarna 9 med motorn 4 och anslutningsnavet 3 förbinds med stoppskruven 6 med axeln 5, allt styrt av passningen mellan motorns 4 axel 5 och anslutningsnavets 3 hål. Därefter lossas skruvarna 22 och 23 och förbindningsdelen 21 tas bort.At the user, the angle measuring device 1 is pushed as a unit connected by the connecting part 21 over the shaft 5 of the motor 4, the stator 7 is connected to the screws 9 with the motor 4 and the connecting hub 3 is connected to the stop screw 6 with the shaft 5, all controlled by the fit between the motor 4 shaft 5 and the connecting hub 3 hole. Then the screws 22 and 23 are loosened and the connecting part 21 is removed.
Vinkelmätanordningen 1 är därefter klar att användas utan att någon justering behövt ske vid monteringen till motorn 4. All justering är gjord hos tillverkaren där lämpliga medel för detta och utbildad personal finns. 455 556 Vid eventueiit demontering av vinkeimätanordningen 1 kan justeringen bibehåïias genom att i omvänd ordning mot vid monteringen åter montera förbindningsdeien Zl innan vinkeimätanordningen 1 iossas från motorns 4 axel 5 5 och monteringsytan 8.The angle measuring device 1 is then ready for use without any adjustment having to take place during mounting to the motor 4. All adjustment is made at the manufacturer where suitable means for this and trained personnel are available. 455 556 In the event of disassembly of the angle measuring device 1, the adjustment can be maintained by reassembling the connecting part Z1 in reverse order during assembly before the angle measuring device 1 is detached from the shaft 4 of the motor 4 and the mounting surface 8.
