Den kendte teknikThe prior art
For at opnå et godt svejseresultat er der flere faktorer, der skal tages hen-20 syn til. Ikke alene skal man vælge den rigtige svejseteknik, den rigtige strømstyrke, tråd og gasmængde, men svejsestillingen spiller også en væsentlig rolle for resultatet og ikke mindst for arbejdsmiljøet for svejseren.In order to obtain a good welding result, there are several factors to consider. Not only do you have to choose the right welding technique, the right current, wire and gas quantity, but the welding position also plays a significant role for the result and not least for the working environment for the welders.
Svejseopgaver byder ofte på det problem, at svejsesømmene skal lægges 25 på flader, der kan være orienteret forskelligt i rummet. Ved vanskelige svejsepositioner vil svejseren derfor ønske at kunne dreje svanehalsen I forhold til håndgrebet for derved at få en bedre arbejdsstilling og ergonomi og dermed en aflastning af håndled, albueled og skulderled.Welding tasks often present the problem that the welding seams must be laid 25 on surfaces that may be oriented differently in space. Therefore, in difficult welding positions, the welder wants to be able to turn the swan neck in relation to the handle in order to obtain a better working position and ergonomics and thus a relief of the wrist, elbow joint and shoulder joint.
30 Det har i mange år været muligt at købe svejsebrændere, hvor der er indskudt et drejeligt led på svanehalsen uden for håndgrebet. Det drejelige led 9 DK 176936 B1 2 er udført af to koblingsparter med en kompliceret udformning, der skal sikre, at kanalerne for gas og vand forbliver intakte ved drejning af svanehalsen. Der er indført tætninger for både gas og vand indvendigt i drejeled-det.30 For many years it has been possible to buy welding torches where a swivel joint is inserted on the swan neck outside the handle. The swivel joint 9 is made of two coupling parts with a complicated design to ensure that the gas and water channels remain intact when the swan neck is turned. Seals for both gas and water have been introduced inside the swivel joint.

Denne svejsebrænder har en række ulemper. Det er forholdsvis tungt i sammenligning med en svejsebrænder uden drejeligt led. Tætningerne er udført med et sæt O-ringe hvilket betyder, at tætningerne skal kontrolleres hyppigt for slid, idet en utæthed vil afstedkomme en svejsning, der er fejl-10 behæftet. Denne type svejsebrænder er dyr, hvorfor den kun har været brugt i begrænset omfang. Imidlertid viser brugerundersøgelser, at behovet er til stede, og at funktionen er efterspurgt.This welding torch has a number of drawbacks. It is relatively heavy in comparison to a non-rotatable welding torch. The seals are made with a set of O-rings, which means that the seals must be checked frequently for wear, as a leak will cause a weld that is defective. This type of welding torch is expensive, so it has been used only to a limited extent. However, user surveys show that the need is present and that the feature is in demand.
Dokumentet EPQ917923 A2 angår en svejsebrænder, som omfatter et 15 håndgreb dannet af to skalparter, hvori der er anbragt et tilslutningselement for tråd, gas, køleluft eller kølevand, og hvortil yderligere en svanehals, der er udstyret med et dysearrangement, er tilkoblet samt en styrestrømskontakt.Document EPQ917923 A2 relates to a welding torch which comprises a handle formed by two shell parts in which a connecting element for wire, gas, cooling air or cooling water is provided, to which a further swan neck equipped with a nozzle arrangement is connected as well as a control current contact. .
20 Svanehalsen kan drejes op til 360 grader i forhold til det øvrige håndtag.20 The swan neck can be rotated up to 360 degrees relative to the other handle.
Derfor er den forreste holder udstyret med fordelingshuller til gas og kølevand, og mellem denne holder og svanehalsen er der indskudt en gummipakning som tætningselement. Denne konstruktion er derfor behæftet med problemer med slid og utætheder.Therefore, the front holder is equipped with distribution holes for gas and cooling water, and between this holder and the swan neck a rubber gasket is inserted as a sealing element. This construction is therefore subject to wear and leakage problems.

Formålet med opfindelsenThe object of the invention
Det er formålet med opfindelsen at afhjælpe disse mange ulemper, og dette 30 opnås ved, at håndgrebet og tilslutningselementet hver er udstyret med en tandkrans eller segmenter af en tandkrans udformet til at gå i indgreb med » DK 176936 B1 3 hinanden, og at indgrebet låses med en på håndgrebet anbragt låsemekanisme.SUMMARY OF THE INVENTION The object of the invention is to overcome these many disadvantages, and this is achieved by the fact that the handle and the connecting element are each equipped with a tooth ring or segments of a tooth ring designed to engage each other and that the engagement is locked. with a hand-held locking mechanism.
Ved at indføre en tandkrans som anført opnår man på fordelagtig vis at 5 kunne foretage en indstilling af positionen mellem håndgreb og svanehals ved blot at udløse låsemekanismen. Endvidere opnår man at kunne tilbyde denne funktion ved få og enkle tilpasninger af allerede eksisterende komponenter, og man undgår problemer med utætte pakninger. Herved holdes kostprisen på et niveau, som er sammenligneligt med en standard svejse-10 brænder. Funktionen medfører heller ikke nogen væsentlig forøgelse af vægt eller størrelse i forhold til kendte brændere.By introducing a dental wreath as stated, it is advantageously achieved that 5 can adjust the position between the handle and the swan neck by simply releasing the locking mechanism. Furthermore, it is possible to offer this function through few and simple adaptations of pre-existing components and avoids problems with leaky gaskets. This keeps the cost level at a level comparable to that of a standard welding torch. The function also does not result in any significant increase in weight or size over known burners.

Fig-1 viser et billede af svejsebrænderen 1 set i perspektiv. Svejsebrænderen er vist med et håndgreb 2, som er dannet af en øvre skalpart 3 og en nedre skalpart 4. Fra forkanten af håndgrebet udgår svanehalsen 6, der 30 afsluttes med et dysearrangement 7. Håndgrebets bagkant er udstyret med et drejeligt led 8, som leder en svejseslange (ikke vist) ind i håndgrebet. På a 6 DK 176936 B1 forkanten af håndgrebet er der monteret en låsemekanisme 11, hvoraf kun omløberen 10 kan ses på figuren. Under håndgrebet er der anbragt en styrestrømskontakt 9.Fig. 1 is a perspective view of the welding torch 1. The welding torch is shown by a handle 2 formed by an upper shell portion 3 and a lower shell portion 4. From the leading edge of the handle, the swan neck 6 is terminated, which is terminated by a nozzle arrangement 7. The rear edge of the handle is provided with a swivel joint 8 which guides a welding hose (not shown) into the handle. On a 6 DK 176936 B1 front edge of the handle is mounted a locking mechanism 11, of which only the bypass 10 can be seen in the figure. During the handle a control current contact 9 is arranged.
5 Svejsebrændere af den viste type kan indrettes til vandkøling eller luftkøling.5 Welding burners of the type shown can be arranged for water cooling or air cooling.
Det indre af håndgrebet 2 er vist på fig. 2 og fig. 3. Her ses hvorledes tilslutningselementet 5 er lejret, og at det er fast forbundet med svanehalsen 10 6. Svejseslangen (ikke vist) føres ind i håndgrebet via det drejelige led 8, som er anbragt bag på håndgrebet, til tilslutningselementet 5 via et antal koblinger udformet til tråd, gas, køleluft eller kølevand.The interior of the handle 2 is shown in FIG. 2 and FIG. 3. Here it is seen how the connection element 5 is mounted and that it is firmly connected to the swan neck 10 6. The welding hose (not shown) is inserted into the handle via the swivel joint 8 located at the rear of the handle to the connection element 5 via a number of couplings. designed for wire, gas, cooling air or cooling water.
Snitbilledet på fig. 3 viser låsemekanismen 11 med omløberen 10, lejet 22 15 og hulrummet 12. I hulrummet anbringes en fjeder eller en gummiring, f.eks. en O-ring (ikke vist) til optagelse af eventuelle produktionstolerancer mellem delene i låsemekanismen. Fjederen eller gummiringen sikrer, at der altid vil være et tryk til stede mellem omløberen 10 og tilslutningselementet 5, som vil presse tilslutningselementet 5 bagud inde i håndgrebet.The sectional view of FIG. 3 shows the locking mechanism 11 with the wrap 10, the bearing 22 15 and the cavity 12. A spring or a rubber ring, e.g. an O-ring (not shown) for recording any production tolerances between the parts of the locking mechanism.

Fig. 4 viser et perspektivbillede af tilslutningselementet 5. Her ser man, hvorledes elementet et udformet som et cylindrisk legeme, der kan rotere inde i håndgrebet. Desuden ser man, at det i den ene ende er udstyret med en tandkrans 13, 15, der udstrækker sig rundt om det cylindriske legeme i 25 hele omkredsens udstrækning. Tandkransen kan dog også være opdelt i et antal segmenter 15 med et vilkårligt tandantal.FIG. 4 shows a perspective view of the connecting element 5. Here it is seen how the element one is designed as a cylindrical body which can rotate inside the handle. Furthermore, it is seen that at one end it is provided with a dental ring 13, 15 extending around the cylindrical body for the entire circumference of the circumference. However, the dental crown may also be divided into a number of segments 15 with any number of teeth.
Tandkransen 13 eller segmentet 15 er på fordelagtig vis udført med en deling D (se fig. 4a), som svarer til syv tænder på et halvfems graders cir-30 keludsnit. Herved opnår man at få et tilstrækkeligt antal indstillingspositioner til at opfylde alle praktiske indstillingsønsker.The tooth ring 13 or segment 15 is advantageously formed with a pitch D (see Fig. 4a) corresponding to seven teeth on a ninety degree circle section. This provides you with a sufficient number of setting positions to meet all practical setting requirements.
DK 176936 B1 9 7 Tændernes længde fra top til bund er valgt således, at længden mindst er på tre millimeter, men en anden længde vil kunne vælges.DK 176936 B1 9 7 The length of the teeth from top to bottom is chosen so that the length is at least three millimeters, but another length can be chosen.
5 Fig. 5 viser i perspektiv opbygningen af den forreste del af håndgrebet 2.FIG. 5 shows in perspective the structure of the front part of the handle 2.
Den nedre skalpart 4 er her vist med en halvpart af en tandkrans 14, eller et segment af en tandkrans 16. Den øvre skalpart 3 er ligeledes udstyret med en halvpart af en tandkrans 14, eller et segment af en tandkrans 16. Tænderne er udført med en deling D, som svarer til syv tænder på et halvfems 10 graders cirkeludsnit. Herved opnår man at få et tilstrækkeligt antal indstillingspositioner til at opfylde alle praktiske indstillingsønsker.The lower shell portion 4 is shown here with a half of a dental crown 14, or a segment of a dental crown 16. The upper shell portion 3 is also provided with a half of a dental crown 14, or a segment of a dental crown 16. The teeth are made with a partition D which corresponds to seven teeth on a ninety 10 degree circle section. This provides you with a sufficient number of setting positions to meet all practical setting requirements.
Tændernes længde fra top til bund er valgt således, at længden mindst er på tre millimeter, men en anden længde vil kunne vælges.The length of the teeth from top to bottom is chosen such that the length is at least three millimeters, but another length can be chosen.
15 Tænderne på begge tandkranse 13, 14 er udformet med ens tandprofiler, så at de passer nøjagtigt ind i hinanden. Imidlertid vil de også kunne udføres med en profil, hvor tandflankerne ikke har præcis samme hældning, så at tænderne sammenkiles lige før en tandtop og en tandbund berører hin-20 anden, når tandkransene trykkes sammen. Herved opnår man at få en fast kobling uden slør.15 The teeth of both dental crowns 13, 14 are formed with similar tooth profiles so that they fit exactly together. However, they will also be possible with a profile where the tooth flanks do not have exactly the same inclination, so that the teeth are peeled just before a tooth tip and a tooth bottom touch each other when the dental crowns are pressed together. This results in a fixed coupling without a veil.
Tandkransen 14 eller tandkranssegmentet 16 er udformet, så tænderne er rettet fremad mod håndgrebets forreste kant (21). Tandkransen 13 og tand-25 kranssegmentet 15 på koblingselementet 5 er udformet, så tænderne er rettet bagud og bort fra svanehalsen 6. Herved opnår man at kunne trække koblingselementet og håndgrebet ud af indgreb med hinanden og rotere koblingselementet en eller flere positioner.The gear ring 14 or the gear ring segment 16 is formed so that the teeth are directed forwardly towards the leading edge (21) of the handle. The toothed ring 13 and the toothed ring segment 15 on the coupling element 5 are formed so that the teeth are directed backwards and away from the swan neck 6. This allows the coupling element and the handle to be pulled out of engagement with one another and rotate the coupling element one or more positions.
30 For at kunne fjerne indgrebet er det nødvendigt først at udløse låsemekanismen 11.30 In order to remove the engagement it is necessary to first release the locking mechanism 11.

DK 176936 B1 8 Låsemekanismen er opbygget af en på håndgrebets skalparter 3,4 udadvendende friktionslås 19. Friktionslåsen forløber delvis på tværs og delvis på skrå af håndgrebets centerlinie. Friktionslåsen er på den tværstil-5 lede del udstyret med mindst en ribbe 20, som låser omløberen fast i arbejdsstillingen. Den skråtstillede del afsluttes med en knast 23, der forhindrer, at omløberen falder af. Begge skalparter 3,4 er udstyret med en udadvendende friktionslås 19.DK 176936 B1 8 The locking mechanism is made up of a friction lock 19, which extends outwardly on the handle parts 3.4. The friction lock extends partly transversely and partly obliquely of the center line of the handle. The friction lock is provided on the transverse part with at least one rib 20, which locks the encoder in the working position. The inclined portion is terminated with a cam 23 which prevents the bypass from falling off. Both shell parts 3,4 are equipped with an outward friction lock 19.
10 Endvidere omfatter låsemekanismen som vist på fig. 6 en omløber 10, der er udstyret med indadvendende låseknaster 18, der er udformet, så at de kan gå i indgreb med friktionslåsen 19 på håndgrebet.Further, the locking mechanism as shown in FIG. 6 shows an encoder 10 equipped with inwardly locking lugs 18 which are designed to engage the friction lock 19 on the handle.
Omløberen 10 er udformet i et fleksibelt materiale, så at en rotation af 15 omløberen muliggøres ved, at omløberen deformeres en smule, når knasterne 18 føres forbi ribberne 20 i friktionslåsen 19.The bypass 10 is formed of a flexible material so that a rotation of the 15 bypass is made possible by slightly deforming the bypass as the lugs 18 pass the ribs 20 in the friction lock 19.
Når omløberen 10 roteres, åbnes låsemekanismen 11, og friktionslåsens skrå forløb medfører, at omløberen forskydes aksialt ved en mindre rotation 20 således, at der bliver plads til at trække tandkransene ud af indgreb med hinanden. Forskydningen antager i en fordelagtig udformning mindst værdien tre millimeter ved en rotation på mindst 15 grader, men andre værdier som f.eks. fem millimeter ved sytten graders rotation kan vælges.As the encoder 10 is rotated, the locking mechanism 11 is opened and the inclined course of the friction lock causes the encoder to be displaced axially by a smaller rotation 20 so as to leave space for pulling out the dental crowns out of engagement with one another. In an advantageous configuration, the displacement assumes at least the value of three millimeters at a rotation of at least 15 degrees, but other values such as five millimeters at seventeen degree rotation can be selected.
