Vynález rieši zariadenie na ustavovanie aupínanie mikrovrtákov.The present invention provides a device for aligning micro drills.

Pomocou doposial' známých a vel'mi roz-šířených zariadení na upínanie mikrovrtá-kov do vřtacieho vřetena sa upínanie vyko-nává dvomi vidlicovými klúčmi, čo je po-měrně nepraktické a to z dovodu, že pra-covník je nútený jednou rukou klúčom fixo-vat pracovně vřeteno a druhou rukou s dru-hým kfúčom stahovat upínaciu maticu. Vr-ták sa přitom predom musí spravidla výš-kové ustavit, napr. na pevný podložný do-raz. Ďalšie známe přípravky sú zameranéhlavně na uthčenie manipulácie při upínaní,resp. vyberaní vrtáka z pracovného vřete-na. Jeden kíúč sa spravidla nahradzuje špe-ciáinou poistkou na fixovanie vřetena, na-příklad kolíkom, západkou a pod., čím sajedna ruka pracovníka uvolňuje. V tomtopríprade na stiahnutie upínacej matice sta-čí len jeden vidlicový kl'úč. Tak isto ako upredchádzajúceho sposobu ustavovania savrták výškové ustavuje spravidla na pevnýpodložný doraz. Nevýhodou je to, že nie jemožné správné výškovo ustavit vrták, takako je to nutné u NC strojov. Popísané za-riadenia sa v strojárskej praxi používajú vCSSR i v zahraničí, napr. pri upínaní růz-ných nástrojov do obrábacích strojov priručnom, elektrickom, pneumatickom nářadía pod. Ich nedostatky sú v sťaženej mani-pulácii pri upínaní vrtáka pomocou ďalšie-ho náradia.By means of the so far known and widely distributed micro-drilling devices for the drilling spindle, the clamping is carried out by two fork-type keys, which is relatively impractical in that the workman is forced by a single-handed key fixo -the working spindle and the other hand with the second spanner pull the clamping nut. At the same time, the turret must generally be leveled, for example, on a solid foundation. Other known formulations are mainly directed to the tightening of the clamping or tampering. removing the drill bit from the working spindle. Typically, one key is replaced by a special spindle lock, such as a pin, latch, and the like, thereby releasing the operator's hand. In this case, only one fork wrench is sufficient to pull the clamping nut. As well as the previous method of alignment, the height-adjustable tumbler is usually set to a rigid stop. The disadvantage is that it is not possible to set the drill bit correctly, as is necessary for NC machines. The described devices are used in mechanical engineering in the USSR and abroad, eg when clamping various tools into machine tools, electric, pneumatic tools. Their drawbacks are in the complicated handling of the drill bit by means of additional tools.

Vyššie uvedené nedostatky súčasného sta-vu techniky sú odstránené zariadením na u-stavovanie a upínanie mikrovrtákov podl'avynálezu, ktorého podstatou je to, že v tu-hom telese je v hornej stredovej časti vy-tvořená priebežná drážka, pod ktorou je vkruhovom otvore nalisované nekovové puz-dro s osadením, pričom v strednej časti tě-lesa je vytvořený priebežný otvor drážkovi-tého tvaru, do ktorého v spodnej častivyúsťuje stavacia skrutka v hornej časti u-pravená do tvaru zrezaného kužeía, stava-cia skrutka je v spodnej časti telesa poiste-ná maticou, pričom teleso je po stranách vstrednej časti opatřené dvomi ramenami.The aforementioned drawbacks of the current state of the art are eliminated by the micro-drilling and clamping device of the invention, the principle of which is that a continuous groove is formed at the top of the body at the bottom of the body, below which a circular opening is pressed a non-metallic housing with a continuous slot-shaped opening formed in the central part of the body, into which the adjusting screw in the upper part of the cut-out cone forms at the bottom, the setting screw being at the bottom of the body with a nut, the body having two arms on the sides of the central part.

Zariadenie na ustavovanie a upínanie mi-krovrtákov podfa vynálezu představuje no-vý progresívny upínací prípravok, ktorý jezvlášť výhodné využitelný v sériovej a hro-madnej výrobě, napr. pri vrtaní otvorov doplošných spojov, kde je spravidla viac dosákpod sebou. Zariadenie umožňuje vždy správ-né nastavit požadovanú dížku vysunutejčasti mikrovrtáka voči mikroklieštine, resp.kiieštine vřtacieho vřetena, ktorú je možnédobré vizuálně kontrolovat. Zariadenie u- možňuje používať mikrovrtáky s použitímmikroklieštiny, ale aj mikrovrtáky s jednot-nou stopkou, ktorá má priemer totožný smikroklieštinou. Nakolko mikrovrták je u-ložený v telese přípravku, je zabezpečená ijeho ochrana voči ulomeniu pri neopatrnejmanipulácii. Konštrukcia zariadenia umož-ňuje i viacúčelné využitie. Příkladné vyhotovenie zariadenia na u-stavovanie a upínanie mikrovrtákov je zná-zorněné na priloženom výkrese na obr. 1,kde je celkový pohlad spředu.The drill locating and clamping device of the present invention is a new progressive fixture which is particularly advantageous in mass production and mass production, for example, for drilling holes in flat joints where there are generally more subsoils. The device always makes it possible to correctly set the desired length of the micro-drill part to the micro-sheath or spindle spindle that can be visually inspected. The device makes it possible to use micro-drills with microcrystals, but also micro-drills with a uniform shank, which has a diameter identical to smikroklie. As the micro-drill is embedded in the body of the preparation, it is also provided with protection against breakage during unintentional manipulation. The design of the device also allows for versatile use. An exemplary embodiment of a micro drill mounting and clamping device is shown in the accompanying drawing in FIG. 1, where the overall view is front.

Zariadenie na ustavovanie a upínaniemikrovrtákov pozostáva z tuhého telesa 1,ktoré je po stranách v strednej časti opat-řené dvomi ramenami 7. V telese 1 v hor-nej stredovej časti je vytvořená pozdížnapriebežná drážka 2, v střede ktorej je vy-tvořený kruhový otvor. V kruhovom otvoreje nalisované nekovové puzdro 3 s osade-ním. V strednej časti telesa 1 pod kruhovýmotvorom je vytvořený priebežný otvor 4drážkovitého tvaru, do ktorého v spodnejčasti vyúsťuje stavacia skrutka 5, ktorá jev hornej časti upravená do tvaru zrezané-ho kužela. Zospodu telesa 1 je stavaciaskrutka 5 poistená maticou B. Pri používanízariadenia podlá vynálezu sa postupuje tak,že do nalisovaného nekovového puzdra 3 sosadením sa zasunie mikroklieština 9 až nadorazovú plochu. Cez mikroklieštinu 9 sazasunie mikrovrták 8 až na spodnú dorazo-vú stavaciu skrutku 5, ktorá sa predom na-staví na požadovanú výšku podlá konkrét-nej požiadavky. V případe použitia mikro-vrtáka 8 s jednotnou stopkou 0 3,175 mmsa nepoužívá mikroklieština 9 a mikrovrták8 sa nasadí priámo do nalisovaného neko-vového puzdra 3 a dotlačí sa na dorazovústavaciu skrutku 5. Následné sa zariadenienasunie mikroklieštinou 9, resp. stopkoumikrovrtáka 8, ktorý má unifikovaný prie-mer stopky ako vonkajší priemer mikro-klieštiny 9, do otvoru klieštiny 11 vřtaciehovřetena. Po predchádzajúcom zafixovaníklieštiny 11 vřtacieho vřetena sa zariade-nie postupné zasúva do otvoru klieštiny 11vřtacieho vřetena a priebežná drážka 2 sazasúva na plošky upínacej matice 10 vřete-na. Po nasunutí na doraz sa celým zariade-ním otáča pomocou dvoch ramien 7 pokialnenastane utiahnutie mikrovrtáka 8. Potomsa zariadenie smerom nadol vysunie z klieš-tiny 11 vřtacieho vřetena a tým je mikro-vrták 8 upnutý.The locating and clamping device consists of a rigid body 1 which is provided on its sides in the middle with two arms 7. In the body 1 in the upper middle part there is formed a longitudinal groove 2 in the center of which a circular opening is formed. A non-metallic housing 3 with a shoulder 3 is pressed in a circular opening. In the central part of the body 1, below the annular body, a through-hole 4 is formed in the groove, into which an adjusting screw 5, which is arranged in the upper part in the shape of a truncated cone, opens in the lower part. At the bottom of the body 1, the adjusting screw 5 is secured by a nut B. In the use of the device according to the invention, the microclimate 9 is inserted into the crimped non-metallic casing 3 by inserting it up to the stop surface. Through the micro-shell 9, the micro-drill 8 moves up to the lower stop screw 5, which is pre-set to the desired height according to the particular requirement. In the case of using a micro drill bit 8 with a uniform shank of 0 3.175 mmsa, the microcrystal 9 is not used and the micro drill 8 is inserted directly into the pressed non-metallic sleeve 3 and pressed against the stop screw 5. a drill bit 8 having a unified shank diameter as the outer diameter of the micro-collet 9, into the collet hole 11 of the spindle. After the previously fixed spindle spindle nut 11 has been inserted, it is inserted sequentially into the hole of the spindle tongs 11 and the continuous groove 2 squeezes onto the spindle nut surfaces 10 of the spindle. After sliding into the stop, the micro-drill 8 is rotated with two arms 7 through the entire arm 7. The device is then moved downwards from the spindle tine 11 and the micro-drill 8 is clamped.
