CLASS 47 a: INT. CLASS F 06 b PATENT TIME FROM 14 APRIL 1959 PROVIDED 6 JULY 1961 PUBLISHED 12 SEPTEMBER 1961 Ans. 3559/1959 on 14/4 1959Harti11 a drawing 0 V THORBORG, STOCKHOLM Device for freezing nuts Nfir there are devices for loading nuts aro these as a rule, as they are parts of the nut, ie. where it is a question of so-called id nuts, placed either to the crown of the nut or to the base of the nut. This is also the case where the freewheel nut, such as spring washers, scissor sticks, etc., applies. The type of nutmeg is mainly determined, with the exception of Iran's economic considerations, by the requirements on the form of leasing, which are at hand. But other factors must also be taken into account, such as the readiness of the weld against the base of the nut as well as against passages entering the weld, the risk of intrusion of foreign particles or substances into the weld mechanism, the heat and cold resistance of the weld, etc. In the present invention - a device for nut welding with a modification for sable welding as sealing of screw connections - the consideration has been given to the cooling process as to all the other factors mentioned above of importance for the versatile use of a welding nut.
Uppfinningen kommer nu att beskrivas med hansvisning till bifogade ritning, i vilken fig. 1 visar muttern underifran, fig. 2 ett vertikalsnitt genom bull, mutter och lasorgan och fig. 3 tva olika typer av lasorgan. The invention will now be described with reference to the accompanying drawing, in which Fig. 1 shows the nut from below, Fig. 2 a vertical section through bull, nut and welding means and Fig. 3 two different types of welding means.
Anordningen enligt uppfinningen bestar av tva skilda, vid lasningstillfallet sanamanforda och samverkande delar: En• mutter 1 med dess has utfort med mutterns centrum koncentriskt och mot bultgangan oppet spar 2 avsett for mutterns lasorgan 3 samt ett ringformat lasorgan bestaende av skruvfjfider 3a eller av elastiskt organiskt material 3b sasom exempelvis kautschuk eller nylon avsett att intvingas i sparet vid mutterns dragning mot ett underlag. Lasorganet, som foretradesvis har helt rund tvarsektion, dr utfort att utan glapprum kunna tradas ph den bult 4, ph vii-ken muttern skall dragas, och med en yttre omkrets storre On muttersparets, dock icke stone an att lasorganet vid mutterns dragning mot underlaget tvingas in i sparet. Vad mutt em betraffar kan den utfOras med si pass vidgad bas, att dess:anliggningsyta penseras for dari upptagen sparoppning. Vid mutter framstalld genom varm- eller kallslagning betyder detta ingen materialfi5rlust och ej heller flagon teknisk svarighet. Muttern kan vidare utforas med ett smalt bratte 5 in dyer sparet 2 for att lasorganet 3 skall folja med muttern 1, nar denna drages av bulten 4, och for att ytterligare forhindra att mutter och lasorgan skiljas it vid starka vibrationer eller andra pafrestningar. Framstalles muttern genom t. ex. kallslagning, kan brattet litt astadkommas genom rundstukning av sparkanten. For att forhindra att mutter avsedd for bruk i samverkan med lb.sorgan av typ 3b vid uppskruvningsrorelse glider i forhfillande till detta, utfores lampligen spa.- ret 2 med tvargaende rannor, eggar e. d. som faste for lasorganet 3. The device according to the invention consists of two different, in the case of welding the same and cooperating parts: A nut 1 with its has been made with the center of the nut concentric and towards the bolt passage open groove 2 intended for the nut's welding means 3 and an annular welding means consisting of screw springs 3a or of elastic organic material 3b such as rubber or nylon intended to be forced into the groove when the nut is pulled against a surface. The welding member, which preferably has a completely round cross-section, is designed so that it can be threaded without a clearance at the bolt 4, at which the nut is to be drawn, and with an outer circumference larger than the nut pair, but not without the welding member being forced to pull the nut towards the ground. into the savings. As far as mutt is concerned, it can be carried out with such a widened base, that its contact surface is compensated for the savings opening occupied therein. In the case of a nut made by hot or cold beating, this does not mean a loss of material, nor does it mean technical liability. The nut can further be formed with a narrow steep 5 in the groove 2 for the welding member 3 to follow with the nut 1 when it is pulled by the bolt 4, and to further prevent the nut and welding member from separating in the event of strong vibrations or other stresses. The nut is produced by e.g. cold beating, the steepness can be achieved a bit by rounding the cutting edge. In order to prevent the nut intended for use in conjunction with type 3b lb. members during screw-up movement from slipping in anticipation of this, the groove 2 is suitably made with transverse grooves, edges, etc. as fasteners for the welding member 3.
Vid anvandningen av derma lfisanordning fores f8rst lasorganet 3 ett stycke ned Over bulten 4 och garna ned till underlaget, varefter muttern 1 drages pa bulten. Vid de sista skruvrorelserna Over underlaget tvingas lasorganet in i sparet. Nar det galler ett lasorgan av skruvfjader 3a, tippas fjaderns slingor av dessa skruvrorelser och komma sedan att verka som sparrhakar vid mutterns ansats till lossnande. LAsorganet av elastiskt organiskt material 3b tvingas med en del av sin massa in i bultens gangor att Or under starkt tryck verka som ett effektivt hinder mot mutterns lossnande samtidigt som det liven trycker mot underlaget och utovar friktion darstades. Detta lasorgan nig& dessutom en tatningsdetalj I lasforbandet, ett forhallande av betydelse I manga sammanhang. En ytterligare fOrdel Or att det icke ph nagot satt kan skada bultens ganger. Dar det ir underlagset lasorganet av skruvfjader Or i fraga om varme- och koldbestandighet, i fraga om bevarandet av full effekti-vitet vid mangfaldiigt upprepade paoch avskruvningar av muttern och i fraga om svarighetsgraden vid mutterns avskruvning, som, dar lasorgan av skruvfjader 3a kommit till anvandning, kan goras med blotta handen efter det att slingornas Overknackning agt rum. Lasorganerav .elastiskt organiskt mate- 2- kan utforas med ett vertikalt brott dess omkrets eller- med ett appet segment for att Ora det mojligt att anvanda lasorganet i fraga pa bultar med nagot varierande tjoelxlek samt far att underlatta dess inglidning mutterns spar 2 och i o. m. detta, ddr lasorganet dr av obetydlig plasticitet; avlagsna rislord& dess sonderbrytande eller annan.funk, tionsstOrande skaleverkan. When using this locking device, the laser means 3 is first moved a distance down over the bolt 4 and the yarns down to the base, after which the nut 1 is pulled on the bolt. At the last screw movements Above the ground, the laser means is forced into the groove. When a welding means of coil spring 3a is gridded, the loops of the spring are tipped by these screw movements and then come to act as ratchets at the nut's approach to loosening. The load member of elastic organic material 3b is forced with a part of its mass into the passages of the bolt that Or under strong pressure acts as an effective obstacle to the loosening of the nut at the same time as it presses against the ground and exerts friction. This welding device also has a sealing detail in the welding joint, a behavior of importance in many contexts. A further advantage Or that it is not ph anything set can damage the bolt times. In the case of the coil spring locking means Or in the case of heat and cold resistance, in the matter of maintaining full efficiency in the case of multiple repeated unscrewings of the nut and in the case of the degree of responsiveness of the screw unscrewing of the nut, which use, can be done with the bare hand after the loops' overtaking has taken place. Welding means of .elastic organic material- 2- can be made with a vertical break its circumference or- with an appet segment to make it possible to use the welding means in question of bolts with slightly varying thickness and to facilitate its sliding of the nut groove 2 and in about this, ddr lasorganet dr of insignificant plasticity; avlagsna rislord & dess sonderbrytande eller annan.funk, tionsstOrande skaleverkan.
Fardelarna med anordningen med ett mutterlas i tva delar enligt denna uppf inning framfor lasmuttrar forsedda med ett med mutt em fast sammanhorande- lasorgan verkande i mutterns has dro att lasorganet i det senare fallet maste konstrueras aft verka mot mutterns underlag, dd det i annat fall skulle inkrakta p mutterns bultoppning och hindra mutterns paforande pa bulten. Lasning mot underlaget maste av skill sasom lasformagans myeket begransade raekvidd i bultens axial-led„ risken fOr skador pa underlaget etc. anses mindre andamalsenlig an lasning mot bultens gangor. Vid lasning med lasmuttrar med lasorgan infallda och fasthallna i spar i mutterns kron sker lasningen oftast med hjalp av lasorgan av vulkanfiber eller nylon, viIkas inre periferi nar in Over mutterns gangor och som yid mutterns padragning med nagot av sin massa tranger in i bultens gangor. Det friktionstryck, som darvid uppstar, dr dock betydligt svagare an det friktionstryek, som astadkommes av ett lasorgan av likartat material enligt liar foreliggande uppfinning, ddr lasorganets massa under betydligt hdgre tryek tvingas in i bultens gangor. En annan vasentlig fordel med det tvadelade mutterlaset enligt uppfinningen framfOr lasmuttern med fast lasorgan ar att ieke hela mutterlaset behover vrakas, darfor att lasorganet blivit odugligt, ntan att derma detalj utan vidare kan utbytas mot en ny. En yttedigare fardel med mutteraset enligt uppfinningen framfor lasmuttrarna med lasorganet infant i mutterns kron ar de plane saval topp- som bottenytor, som den forstnamnda konstruktionen uppvisar till skillnad frail de senare, has vilkn mutterkronet utforts med en krage for fasthallande av lasorganet. En plan toppyta hos muttern kan namligen i vissa fall vam . lampligast eller 4. o. m. oundgangligen nodvandig for- Ott muttern skall kunna anvandas. En ur ekono-: misk synpunkt vasentlig fordel med den mutter, som ingar I uppfinningen, framThr de fiesta am ej alla andra lasmuttrar Or slutligen att den kan framstallas genom kallslagning utan maskinella svarigheter. The parts of the device with the nut with a nut weld in two parts according to this invention in front of weld nuts provided with a mat-fixed weld member acting in the nut has drawn that the weld member in the latter case must be designed to act against the nut base, otherwise it would actuate the nut bolt bolt and prevent the nut from mounting on the bolt. Loading against the ground must be separated as the very limited range of the welding form in the axial joint of the bolt „the risk of damage to the ground etc. is considered less appropriate than loading against the passages of the bolt. When welding with welding nuts with welding means recessed and held in grooves in the crown of the nut, the welding usually takes place with the help of welding means made of volcanic fiber or nylon, the inner periphery is wound in over the nut passages and as the nut padding with some of its mass penetrates the bolt passages. The frictional pressure which thereby arises is, however, considerably weaker than the frictional pressure which is produced by a welding member of a similar material according to the present invention, in which the mass of the welding member under considerably higher pressure is forced into the passages of the bolt. Another essential advantage of the two-part nut weld according to the invention over the weld nut with fixed welding means is that the entire nut weld does not need to be discarded, because the welding means has become incapable, without this detail being easily exchanged for a new one. A more advanced part of the nut shaft according to the invention in front of the lock nuts with the locking member embedded in the crown of the nut is the flat both top and bottom surfaces, which the former construction has, unlike the latter, which has the nut crown made with a collar for holding the locking member. A flat top surface of the nut can in some cases vam. most suitable or 4. o. m. inevitably necessary for- Ott the nut must be able to be used. An economically significant advantage of the nut provided in the invention is that not all other welding nuts, finally, can be produced by cold beating without mechanical similarities.
