Description
15 20 25 30 8205865-2 2 ger dock alltför hög friktion vid de sidkrafter som i praktiken kan upp- träda på benet. 15 20 25 30 8205865-2 2, however, gives too high friction at the lateral forces that can occur in practice on the leg.
Det är vidare känt att vid teleskoparmar för industrirobotar, där de två i varandra rörliga armdelarna har i huvudsak rektangulärt tvärsnitt, använda vinkelrätt mot varandra riktade styrrullar vid diagonalt belägna hörn i tvär- snittet. Rullarna är fast lagrade i den ena av armdelarna. Även denna konstruk- tion är relativt skrymmande. En anna olägenhet ur mekanisk synpunkt är att skillnaden i dimension mellan den inre och den yttre armdelen blir relativt stor. Ändamålet med föreliggande uppfinning är att åstadkomma ett för ovannämnda ändamål avsett konstruktionselement av teleskoptyp, som inte är behäftat med de ovannämnda olägenheterna. Detta uppnås enligt uppfinningen genom en kon- struktion som uppvisar de i kännetecknande delen av patentkrav 1 angivna särdragen. Vid en sådan konstruktion kan skillnaden i dimension mellan det inre och det yttre röret vara liten, varigenom, relativt sett, stabiliteten hos innerröret blir större än vid jämförbara tidigare kända konstruktioner.It is further known that in telescopic arms for industrial robots, where the two mutually movable arm parts have a substantially rectangular cross-section, use guide rollers directed perpendicular to each other at diagonally located corners in the cross-section. The rollers are fixedly mounted in one of the arm parts. This construction is also relatively bulky. Another disadvantage from a mechanical point of view is that the difference in dimension between the inner and the outer arm part becomes relatively large. The object of the present invention is to provide a construction element of telescopic type intended for the above-mentioned purpose, which does not suffer from the above-mentioned disadvantages. This is achieved according to the invention by a construction which has the features stated in the characterizing part of claim 1. In such a construction the difference in dimension between the inner and the outer tube can be small, whereby, relatively speaking, the stability of the inner tube becomes greater than in comparable previously known constructions.
Man får dessutom låg friktion och lågt yttryck, varigenom rören med fördel kan utgöras av strängsnrutade profiler av aluminium eller plast.You also get low friction and low surface pressure, whereby the pipes can advantageously consist of extruded profiles of aluminum or plastic.
Uppfinningen skall ftrklaras närmare under hänvisning till utföringsexempel som visas i bifogade ritning, i vilken fig 1 visar i sidovy ett pulpetbord ned teleskopben enligt uppfinningen, varvid bordcts ben visas i axialsnitt i minimiläget, fig 2 visar på samma sätt pulpetbordet med teleskopbenen i maximiläget, fig 3 visar ett tvärsnitt genom ett av benen efter linjen A-A iffig 2, rig M »isär den av cirkeln B i fig 3 inringade detaljen i större skala, fig 5 visar ett längssnitt genom teleskopbenet efter linjen C-C i fig 3, varvid benet befinner sig i minimiläget, ~ fig 6 visar *å samma sätt teleskopbenet i maximiläget, v fig 7 visar ett tvärsnitt genom ett teleskopben enligt en annan utföringsform av uppfinningen, och 10 15 20 25 30 8205865-2 fig 8 visar i planvy ett nålbandselement av det -lag som används vid upp- finningen.The invention will be explained in more detail with reference to exemplary embodiments shown in the accompanying drawing, in which Fig. 1 shows in side view a desk table down the telescopic legs according to the invention, the table legs being shown in axial section in the minimum position, Fig. 2 similarly shows the desk table with the telescopic legs in the maximum position. Fig. 3 shows a cross-section through one of the legs along the line AA in Fig. 2, apart from the detail circled by the circle B in Fig. 3 on a larger scale, Fig. 5 shows a longitudinal section through the telescopic bone along the line CC in Fig. 3, the bone being in Fig. 6 shows in the same way the telescopic leg in the maximum position, Fig. 7 shows a cross section through a telescopic leg according to another embodiment of the invention, and Fig. 8 shows in plan view a needle band element of the used in the invention.
Det i fig 1 och 2 visade pulpetbordet omfattar en överdel med bärram 2 och bordsskiva 3, en stativdel med två benenheter Ä anordnade vid var sin ände av bordet, samt en mellan benenheterna anordnad underdel 5. Varje benenhet har en fot 6 och ett ben 7, vars längd kan ändras, så att överdelen kan ställas in i olika höjdlägen. Fig 1 visar bordet med överdelen i det nedre ändläget, medan fig 2 visar bordet med överdelen i det övre ändläget.The pulpit table shown in Figs. 1 and 2 comprises an upper part with support frame 2 and table top 3, a frame part with two leg units Ä arranged at each end of the table, and a lower part 5 arranged between the leg units. Each leg unit has a foot 6 and a leg 7 , the length of which can be changed so that the upper part can be adjusted to different height positions. Fig. 1 shows the table with the upper part in the lower end position, while Fig. 2 shows the table with the upper part in the upper end position.
Drivanordningen för höjdjusteringen av bordsskivan omfattar en elmotor som driver en drivaxel 8 på vilken ett band 9 rullas upp. Bandet är förankrat på teleskopbenets rörliga del och går över brytrullar 10 och 11 till drivaxeln 8.The drive device for the height adjustment of the table top comprises an electric motor which drives a drive shaft 8 on which a belt 9 is wound. The belt is anchored to the movable part of the telescopic leg and passes over break rollers 10 and 11 to the drive shaft 8.
Pulpetbordets ben 7, vars utförande visas mera i detalj i fig 3-6, består av två rörformiga delar, nämligen ett yttre rör 12 och ett inre rör 13, vilka båda har huvudsakligen rektangulärt tvärsnitt. Det inre röret 13 har en i längdriktningen styrd teleskopisk rörelse i det yttre röret 12. I det visade utföringsexemplet är rören utförda av aluminium i form av strängsprutade profiler. Även andra material, t ex plast, är dock fullt tänkbara i detta nammanhang.The legs 7 of the pulpit table, the design of which is shown in more detail in Figs. 3-6, consist of two tubular parts, namely an outer tube 12 and an inner tube 13, both of which have a substantially rectangular cross-section. The inner tube 13 has a longitudinally controlled telescopic movement in the outer tube 12. In the embodiment shown, the tubes are made of aluminum in the form of extruded profiles. However, other materials, such as plastic, are also fully conceivable in this name context.
Som framgår av fig 3 är ytterröret 12 försett med längsgående styrlister i form av två inåtriktade mittemot varandra belägna åsar 1H med huvudsakligen triangulärt tvärsnitt. Åsarna passar in i längsgående huvudsakligen V-formade spår 15 1 det inre röret 13x_Mellan åsarna och spårens väggar är linjära rull- lager i form av s k nålband 16 anordnade. Nålbanden 16 löper på slitbanor 17 av t ex stål eller mässing. Om rören 12, 13 är utförda av material som i sig har tillräcklig slitstyrka, är speciella slitbanor inte nödvändiga.As can be seen from Fig. 3, the outer tube 12 is provided with longitudinal guide strips in the form of two inwardly directed ridges 1H with a substantially triangular cross-section. The ridges fit into longitudinally substantially V-shaped grooves 15 in the inner tube 13x. Between the ridges and the walls of the grooves, linear roller bearings in the form of so-called needle bands 16 are arranged. The needle straps 16 run on treads 17 of, for example, steel or brass. If the pipes 12, 13 are made of material which in itself has sufficient wear resistance, special treads are not necessary.
Det inre röret 13 har en längsgående slits 18 med ett tvärsnitt som från ett mittparti kilformigt utvidgar sig såväl mot rörets inre som mot dess periferi.The inner tube 13 has a longitudinal slot 18 with a cross-section which from a central portion wedges extends both towards the interior of the tube and towards its periphery.
I de kilformiga partierna är två spränglister 19, 20 anordnade, vars tvärsnitt kan vara t ex runt eller kilformigt. Spränglisterna är i det närmaste lika långa som det inre röret och är förbundna med varandra medelst skruvar 21 på ungefär var tionde cm. Genom åtdragning av skruvarna drages spränglisterna 19, 20 mot varandra, varigenom det inre röret expanderar och rullagren ansättes.In the wedge-shaped portions two explosive strips 19, 20 are arranged, the cross-section of which can be, for example, round or wedge-shaped. The blasting strips are almost as long as the inner pipe and are connected to each other by means of screws 21 of approximately every tenth cm. By tightening the screws, the blasting strips 19, 20 are pulled towards each other, whereby the inner tube expands and the roller bearings are applied.
Härigenom uppnås en glappfri styrning av teleskoprörelsen med praktiskt taget försumbar friktion. Genom denna anordning kompenseras även måttavvikelser hos 10 15 20 25 30 35 8205865-2 , rören och man får en lagring med stor bäryta, varigenom relativt stora tvär- krafter kan avlastas.This achieves a flawless control of the telescopic movement with practically negligible friction. This device also compensates for dimensional deviations of the pipes and provides a bearing with a large bearing surface, whereby relatively large transverse forces can be relieved.
Nålbanden 16, som är av i marknaden förekommande slag, är uppbyggda av ett antal element av det i fig 8 visade utförandet. Elementet omfattar en i huvud- sak rektangulär plasthållare 22 som uppbär två rader av stålrullar 23, som t ex kan ha en diameter av 2,5 mm och en längd av 10 mm. Hâllaren är utförd med laxspår, som gör det möjligt att förbinda ett godtyckligt antal enheter i rad med varandra. Av fig 5 och 6 framgår att man i det visade utförings- exemplet har sju enheter i varje nålband. Mellan rullraderna har hållaren 22 en elastisk mellandel 2U, vilken kan bockas så att rullraderna kan fås att inta vilken som helst önskad vinkel i förhållande till varandra. I det visade utföringsexemplet är denna vinkel 900 (fig U). Nålbanden hålls i läge i längd- led genom det lagertryok som åstadkommes vid åtdragning av skruvarna 21.The needle straps 16, which are of a type present on the market, are built up of a number of elements of the embodiment shown in Fig. 8. The element comprises a substantially rectangular plastic holder 22 which supports two rows of steel rollers 23, which may, for example, have a diameter of 2.5 mm and a length of 10 mm. The holder is made with salmon grooves, which make it possible to connect any number of units in a row to each other. Figures 5 and 6 show that in the embodiment shown there are seven units in each needle band. Between the roller rows, the holder 22 has an elastic intermediate part 2U, which can be bent so that the roller rows can be made to take any desired angle in relation to each other. In the embodiment shown, this angle is 900 (Fig. U). The needle straps are held in position longitudinally by the bearing pressure created when tightening the screws 21.
Som framgår av fig 5 och 6 är nålbandens rörelse i längdled hälften så stor som rörelsen hos det inre röret 13.As can be seen from Figures 5 and 6, the longitudinal movement of the needle straps is half as large as the movement of the inner tube 13.
Innerröret 13 behöver inte nödvändigtvis vara utförd med öppen profil, utan kan även utföras med sluten profil, så som fig 7 visar ett exempel på. I detta utföringsexempel har vidare slitbanorna 17 slopats, men i övrigt skiljer sig utförandet principiellt inte från det ovan beskrivna.The inner tube 13 does not necessarily have to be made with an open profile, but can also be made with a closed profile, as Fig. 7 shows an example of. In this exemplary embodiment, the treads 17 have further been abolished, but otherwise the embodiment does not differ in principle from that described above.
Ur mekanisk synpunkt är det lämpligt att lagringarna och expansionselementet inte är placerade vid rörprofilernas mitt utan förskjutna så långt som möjligt mot ytterrörets ena smalsida. Därigenom erhålles minsta möjliga utsvällning av ytterprofilen vid åtdragning av expansionselementet.From a mechanical point of view, it is suitable that the bearings and the expansion element are not located at the center of the pipe profiles but are displaced as far as possible towards one narrow side of the outer pipe. As a result, the smallest possible swelling of the outer profile is obtained when tightening the expansion element.
Uppfinningen är inte begränsad till de visade utföringsexemplen, utan flera modifikationer är tänkbara inom ramen för patentkraven. Således kan man, i stället för som visat, anordna innerröret fast och ytterröretnförskjutbart.The invention is not limited to the exemplary embodiments shown, but several modifications are conceivable within the scope of the claims. Thus, instead of as shown, the inner tube can be arranged fixedly and the outer tube displaceable.
Vidare kan i princip styrlisterna 1Ä vara anordnade på innerröret och styr- spåren 15 på ytterröret.De två lagerbanorna på samma sida om expansionsele- mentet behöver dessutom inte vara sammankopplade, och vinkeln mellan dem behöver inte vara 900.Furthermore, in principle the guide strips 1Ä can be arranged on the inner tube and the guide grooves 15 on the outer tube. In addition, the two bearing tracks on the same side of the expansion element need not be interconnected, and the angle between them need not be 900.
Användningsområdet för uppfinningen är inte begränsat till teleskopben för pulpetbord, utan i princip samma konstruktion kan användas exempelvis vid teleskoparmar för industrirobotar, teleskoputliggare för kranar etc. För robotarmar är konstruktionen speciellt fördelaktig genom att lagren tillåter snabba accelerationer p g a rullarnas låga tröghetsmoment.The field of application of the invention is not limited to telescopic legs for desk tables, but in principle the same construction can be used for example with telescopic arms for industrial robots, telescopic outriggers for cranes, etc. For robot arms the construction is particularly advantageous in that the bearings allow fast accelerations due to the rollers' low inertia.
