Description
15 20 25 30 35 459 562 2 friktion, tyngden av bärplattan med tillhörande utrustning och den av motorn och rotationsdrivanordningen åstadkomma rotationshastigheten kan man med enkla medel (jämför kraven 7 - 9 avseende lämpliga material för glidlagringsns glid- element) uppnå, att bärplattan kan vridinställas till exakt önskat läge. Glidfriktionen möjliggör nämligen en mycket kort och kontrollerbar bromsstëcka. Den ändlösa drivremmen ger vidare en glappfri och eáakt rörelseöverföring mellan drivmotorn och bärplattan. '-U Lämpliga ytterligare särdrag hos vridinställningsanordningen enligt uppfinningen anges i underkraven och kommer att fram- gå av nedanstående detaljbeskrivning av en föredragen ut- föringsform, varvid hänvisas till bifogade ritning. Friction, the weight of the support plate with associated equipment and the rotational speed achieved by the motor and the rotary drive device can be achieved by simple means (compare claims 7-9 regarding suitable materials for the sliding bearing sliding elements) that the support plate can be rotatable to the exact desired position. The sliding friction enables a very short and controllable brake pad. The endless drive belt further provides a play-free and smooth transmission of motion between the drive motor and the support plate. Suitable further features of the rotary adjustment device according to the invention are stated in the subclaims and will appear from the following detailed description of a preferred embodiment, reference being made to the accompanying drawing.
Fig. 1 visar schematiskt i centralt tvärsnitt ieärlagda delar ingående i en vridinställningsanordning enligt uppfinningen; Fig. 2 visar i planvy ett i vridinställningsanordningen enligt fig. 1 ingående ringelement med kransformigt "“ fördelade gl idelement; Fig. 3 visar vridinställningsanordningen uppifrån, sedd enligt pilarna III - III i fig. 4, med tillhörande rotationsdrivanordning; Fig. 4 visar ett centralt snitt genom vridinställnings- anordningen enligt fig. 3.Fig. 1 shows diagrammatically in central cross section disassembled parts included in a rotary adjustment device according to the invention; Fig. 2 shows in plan view an annular element included in the rotary adjustment device according to Fig. 1 with ring-shaped sliding elements; Fig. 3 shows the rotary adjustment device from above, seen according to arrows III - III in Fig. 4, with associated rotary drive device; central section through the rotary adjustment device according to Fig. 3.
Den pà ritningen visade vridningsinställningsanordningen (se fig. 4) är placerad på ett fast fundament 1, t.ex. ett golv, pà vilket ett stödelement i form av en cirkulär stödplatta 2 är monterad pà i golvet fastskruvade stödklotsar_3 med hjälp av ställskruvar 4, så att stödplattan 2 hàlles fixerad i önskat, lämpligen horisontellt läge. 10 15 20 25 30 35 ° a 459 562 Stödplattan 2 har ett centralt, cirkulärt hål 5 (fig. 1) och en på ovansidan, koncentriskt på något avstånd från hål- kanten 5a fastsvetsad hållarhylsa 6, som inrymmer en glid- lagringaanordning 7 för en övre, roterbar bärplatta 8. Denna roterbara bärplatta 6 är likaledes cirkulär och försedd med ett centralt hål 9, som avgränsas av en nedåtskjutande flänshylea 10. Bärplattan 8 antages ingå i en rotorbar apparat eller maskin, t.ex. en rundmatare, en material- hanteringsanordning eller induetrirobot, för vilken det.är väsentligt att exakt och repeterbar vridínställning kan åstadkommas.The rotation adjustment device shown in the drawing (see Fig. 4) is placed on a solid foundation 1, e.g. a floor, on which a support element in the form of a circular support plate 2 is mounted on support blocks 3 screwed into the floor by means of adjusting screws 4, so that the support plate 2 is kept fixed in the desired, suitably horizontal position. 35 15 a 25 30 35 ° a 459 562 The support plate 2 has a central, circular hole 5 (Fig. 1) and a holding sleeve 6 welded concentrically at some distance from the hole edge 5a, which houses a sliding bearing device 7 for an upper, rotatable support plate 8. This rotatable support plate 6 is likewise circular and provided with a central hole 9, which is delimited by a downwardly projecting flange shelf 10. The support plate 8 is assumed to be part of a rotatable apparatus or machine, e.g. a round feeder, a material handling device or an induity robot, for which it is essential that precise and repeatable turning adjustment can be achieved.
Glidlagringsanordningen 7 omfattar för detta ändamål ett i stödplattans 2 hållarhylsa 6 ovridbart fastsatt ringelement 11 med invändiga, snett uppåt resp. snett nedåt vända kon- ytor 11a,11b, varvid ett flertal cylindriska glidelement 12a är insatta med presepassning i motsvarande, uppborrade bottenhàl i den övre konytan 11a (jämför fig. 2). Dessa kransformigt fördelade glidelement 12a anligger mot den övre bärplattans 8 flänshylsa 10, vars undre del är avfasad till en motsvarande konyta 10a (fig. 1).For this purpose, the sliding storage device 7 comprises a ring element 11 with internal, obliquely upwards and obliquely upwards, respectively, fixed in the support plate 2 of the support plate 2. obliquely downwardly facing cone surfaces 11a, 11b, a plurality of cylindrical sliding elements 12a being inserted with pre-fitting in the corresponding, drilled bottom hole in the upper cone surface 11a (compare Fig. 2). These ring-shaped sliding elements 12a abut against the flange sleeve 10 of the upper support plate 8, the lower part of which is chamfered to a corresponding cone surface 10a (Fig. 1).
Bärplattan B hållas i stabilt läge enligt fig. 4 medelst en radiellt invändigt anordnad, vertikalt orienterad hylekropp 13, som sträcker sig genom stödplattans 2 och bärplattans 8 centrala hål 5 resp. 9 och vars övre del är fastgängad i bärplattana 8 flänshylsa 10, medan dess undre del har ett radiellt vidgat parti 13a med en utvändig, snett uppåt vänd konyta 13b. Pâ denna konyta 13b är kransformigt fördelade, cylindriska glídelement 12b insatta i borrade bottenhål på samma sätt som glidelementen 12a på konytan lla, så att de båda paren av motstàende konytor 1Ua,11a resp. 11b,13b hållas fixerade mot varandra under förmedling av de båda glidelementuppsättningarna 12a,12b. 10 15 20 25 30 459 562 4 Glidelementen 12a och 12b består lämpligen av ett termo- plastmaterial, som är relativt styvt och har lag friktion gentemot de motstaende konytorna.The support plate B is held in a stable position according to Fig. 4 by means of a radially internally arranged, vertically oriented howling body 13, which extends through the central holes 5 and 5 of the support plate 2 and the support plate 8, respectively. 9 and the upper part of which is threaded into the support plates 8 flange sleeve 10, while its lower part has a radially widened portion 13a with an external, obliquely upwardly facing cone surface 13b. On this cone surface 13b, cylindrically distributed cylindrical sliding elements 12b are inserted in drilled bottom holes in the same way as the sliding elements 12a on the cone surface 11a, so that the two pairs of opposite cone surfaces 1Ua, 11a and 11b, 13b are held fixed to each other while mediating the two slider element sets 12a, 12b. The sliding elements 12a and 12b suitably consist of a thermoplastic material which is relatively rigid and has low friction with respect to the opposite surfaces.
Ett lämpligt material är polyamid, företrädesvis med tillsats av ett smörjmedel, så- som en oljemolekylblandning.A suitable material is polyamide, preferably with the addition of a lubricant, such as an oil molecule mixture.
,Rotationsdrivningen'av bärplattan B relativt stödplattan 2 åstadkommas medelst en servostyrd elmotor 14, som är juster- bart fästad pà birplattans 8 ovansida och medelst'en utgåen- de vinkeltransmíssion 15 och ett kuggdrev 16 står i drivin- grepp med stödplsttane 2 hállarhylsa 6 medelst en ändlös drivslinga i form av en kuggrem 17, vilken är lagd och hálles spänd runt såväl kuggdrevet 16 som en utvändig kugg- krane 18 på hàllarhylsan 6.The rotational drive of the support plate B relative to the support plate 2 is effected by means of a servo-controlled electric motor 14, which is adjustably attached to the upper side of the bearing plate 8 and by means of the outgoing angular transmission 15 and a gear 16 engaged with the support plate an endless drive loop in the form of a toothed belt 17, which is laid and kept tight around both the gear 16 and an external toothed crane 18 on the holding sleeve 6.
Den beskrivna vridinställningsanordningen kan modifieras på màngahanda sätt inom ramen för efterföljande patentkraven.The described rotary adjusting device can be modified in many ways within the scope of the appended claims.
