Snabb chuck. Quick chuck.

Foreliggande uppf inning, :avser en snabbchuck med tapp- :eller rullkroppssparr for ingrepp i kam- eller skruvgangspar i den del, som skall fastas i chucken, vilken chuck har en upptagningshylsa med en mat mot drivspindeln koniskt avsmalnande oppning for den del, soul :skall fastas i chucken, till vilken hylsa sparrkroppen eller -kropparna Oro forlagda, vilka aro anordnade att lasas i sparrlage relativt namnda del av en ph hylsan skjutbar annan hylsa. Uppfinningen bestar I hrtvudsak ddruti att den pa upptagningshylsan skjutbara hylsan ar anordnad att skjutas i och ur sparrlage av en med hada ovannaninda hylsor koneentrisk ytterhylsa, vilken dr anordnad aft samverka med en eller flera i m•ellanhylsan lagrade sparrkroppar for mellanhylsans fOrskjutiiing resp. spanning i det lage, i vilket mellanhylsan laser sp5rrkropparna for den del, som skall fastas i chucken. lippfinningens andamal är bl. a. att Ora lasningen mera tillforlitlig och snabb an -vad som hittills varit mOjligt. Framfor alit mdjlig- gOren sjalvatsattning av verk- tyget i chucken under arbetet utan att lostagandet darfor pa nagot satt forsvaras. The present invention relates to a quick-release chuck with a pin or roller body lock for engaging a cam or threaded pair in the part to be fixed in the chuck, which chuck has a receiving sleeve with a conical tapered opening for the drive spindle for that part, soul: shall be fixed in the chuck, to which sleeve the ratchet body or bodies are placed, which are arranged to be loaded in ratchet position relative to said part of a ph sleeve slidable other sleeve. The invention essentially consists in that the sleeve slidable on the receiving sleeve is arranged to be slid into and out of the ratchet layer by a concentric outer sleeve with the above-mentioned sleeves, which is arranged to cooperate with one or more ratchet bodies stored in the intermediate sleeve for the ratchet bodies. tension in the bearing in which the intermediate sleeve laser the tracer bodies for the part to be fixed in the chuck. The spirit of lip-finding is, among other things. a. to make the lasing more reliable and fast than what has been possible so far. Above all, it is possible to self-place the tool in the chuck during the work without the unloading therefore being defended in any way.

En utforingsform av chucken visas a bifogacle ritning, liars fig. 1 visar ett axialsnitt genom chucken och fig. 2 visar infastningsanden pa. en sadan del, verktyg eller dylikt, soul skall fastas i chuck:en. An embodiment of the chuck is shown in the accompanying drawing, Fig. 1 shows an axial section through the chuck and Fig. 2 shows the fastening spirit pa. such a part, tool or the like, soul shall be fixed in the chuck.

Med 1 pa ritningen betecknas en chuckens kiirila bildande upptagningshylsa, med. 2 en pa derma skjutbar, annan hylsa, i del foljanmellanhylsa, med 3 en denna omgivande ytterhylsa, med 4 en m:edbringartunga, sonn avslutar en Iran karnhylsan ut- formadld, och med 8 betecknas Ovre delen av ett verktyg, som skall fastas i chucken. 1 in the drawing denotes a chuck's kiirila forming receiving sleeve, with. 2 a sliding sleeve, another sleeve, part of the follower intermediate sleeve, with 3 an outer sleeve surrounding it, with 4 a m: edbringartunga, sonn ends an Iran core sleeve designed, and with 8 the upper part of a tool, which is to be fixed in chucken.

Upptagningshylsa 1 liar en inat koniskt avsmalnande oppning for -delen 8. I oppningen i hylsans vagg aro lagrade kulor 7a, som aro anordnad-e att kunna foras i ingrepp med var sitt snett karnspar, t. ex. ett skruvgangspar 8a, i delen 8. I fig. 2 synes endast det ena av d:essa spar. I ingreppslaget inisas kulorna av en konisk yta 2b i mellanhylsan 2, nar den senare skjutes i riktning mot delen 8. Mellanhylsan Or namligen skjutbar pa hylsan 1. The receiving sleeve 1 has a slightly conically tapered opening for the part 8. Balls 7a are stored in the opening in the cradle of the sleeve, which are arranged to be able to be engaged in engagement with their respective oblique pairs of core, e.g. a threaded pair 8a, in part 8. In Fig. 2 only one of these grooves is seen. In the engaging layer, the balls are initiated by a conical surface 2b in the intermediate sleeve 2, when the latter is pushed in the direction of the part 8. The intermediate sleeve Or is namely slidable on the sleeve 1.

Genom att ytan 2b Or konisk, komma kulorna 7a att paverka mellanhylsan 2 i axiell riktning. For att hylsan 2 icke skall forflyttas av det sã uppkomna axiella trycket, finnas kulor (en 7b synes a ritningen), vilka av ytterhylsan 3 vid hist lage hallas intryckta i det svarvad:e sparet la i karnhylsan 1. By making the surface 2b conical, the balls 7a actuate the intermediate sleeve 2 in the axial direction. In order that the sleeve 2 should not be moved by the axial pressure thus obtained, there are balls (a 7b can be seen in the drawing), which of the outer sleeve 3 are historically pressed into the turned-in slot 1a in the core sleeve 1.

Nar hylsan 3 med handen 15res uppitt, kunna kulorna 7h ga in i 'ett spar 3a, varigenom de icke lasa ihop ringen 2 med upptagningshylsan 1. Mir ytterringen 3 Ewes vidare uppat, kommer kanten 3b vid ,ett spar 3e att traffa kulor (a ritningen synes en 7c), varigenom hylsan 2 foljer med i rorelsen uppat, tills den sLoppar mot en i hylsans 1 ytteryht siltande lasring 6a. I detta lage av hylsorna knnna kulorna 7a gO ut i en ursvarvning 2a i mellanhylsan, varigenom det insatta verktyget frigores. When the sleeve 3 with the hand 15 is raised, the balls 7h can enter a groove 3a, whereby they do not weld the ring 2 with the receiving sleeve 1. Mir the outer ring 3 Ewes further up, the edge 3b at, a groove 3e will hit balls (a the drawing shows a 7c), whereby the sleeve 2 follows in the upward movement, until it slopes towards a lasing ring 6a siding in the outer surface of the sleeve 1. In this layer of the sleeves, the balls 7a g0 extend into a recess 2a in the intermediate sleeve, whereby the inserted tool is released.

Nar verktyget skall insattas i chuck-en, hmles hylsan 3 i sitt ovre lage, verktyget halles upp i hylsans 2 kona 'och hylsan 3 fore:s Harvid traffar kanten 3d kulan 7b, varvid hylsan 2 fOljer med i rorelsen. Kilian 7a tryckes darvid in i sparet 8n pa verktyget 8 och nar kulan 7b kommer mitt for spar la, tryckes kulan in i detta spar, ringen 2 slutar da sin r5relse nedat. Hylsan 3 fortsatter rorelsen nedat, tills kanten 3e traffar kulan 7c, varvid rOrelsen stoppas. I delta lage Miler ytan 31 in kulan 7b i sparet la, varigenom hylsan 2 lir last vid hylsan 1. I hylsan 3 Or en bromsring 5 inlagd i eft spar for att forehygga att hylsan, nar chucken anvand:es i horisontalt lage, av vibrationer skall omstalla sig sjalv. I medbringartungan 4 Or ett hal 4a. For att forebygga att chucken oavsiktligt lossnar exempelvis i en borrmaskins:pindel sOLtes ett stilt genom kiljagarhalet i borrspindein in I hal 4a. For fastsattande av chile-ken t. ex. 1 frasmaskin:er hortskruvas medbringartungan 4, varefter chucken kan dragas fast i frasspindeln med dragstang. Hylsan 3 kan fasthallas under det att chucken rote- — — rar, yarefter man genom att fora hylsan uppat, kan vaxla yerktyg titan all behOva stanna maskinen. When the tool is to be inserted into the chuck, the sleeve 3 is held in its upper layer, the tool is held up in the cone 2 of the sleeve and the sleeve 3 is lined: Then the edge hits the ball 7b, whereby the sleeve 2 follows the movement. The wedge 7a is then pressed into the groove 8n on the tool 8 and when the ball 7b comes in the middle of the groove 1a, the ball is pressed into this groove, the ring 2 then ends its movement downwards. The sleeve 3 continues the movement downwards, until the edge 3e hits the ball 7c, whereby the movement is stopped. In the delta Miler surface 31 into the ball 7b in the recess 1a, whereby the sleeve 2 carries a load at the sleeve 1. In the sleeve 3 Or a brake ring 5 inserted in the recess to prevent the sleeve, when the chuck is used in horizontal bearing, from vibrations shall reorganize itself. In the carrier tongue 4 Or a slide 4a. To prevent the chuck from unintentionally coming loose, for example in a drill: spindle, a shaft is inserted through the wedge hopper tail in the drill spindle into hole 4a. For fixing the chile ken e.g. In a milling machine, the carrier tongue 4 is screwed short, after which the chuck can be tightened in the milling spindle with a drawbar. The sleeve 3 can be held in place while the chuck rotates, after which the sleeve titanium can be swapped by feeding the sleeve upwards, all of which need to stop the machine.

Chucken kan 1 och for sitt fastande i maskinen utforas pit olika &Ott t. cx. forses med en hylsa, varmed den kan fastas omkring en spindel. The chuck can 1 and for its fasting in the machine be performed pit different & Ott t. Cx. provided with a sleeve with which it can be fastened around a spindle.

I stallet for kulor kunna rullar eller tap-par anvandas. Kamsnaret 8a kan anordnas med hoger eller vansterstigning, alternativt Oxen sä, att verktyget pressas upp i upptagningshylsans kona i bada rotationsriktningarna. Instead of balls, rollers or loss pairs can be used. The cam string 8a can be arranged with a right or left ridge, alternatively the ox so that the tool is pressed up into the cone of the receiving sleeve in both directions of rotation.
