Vynález sa týká nástroje na leStenie otvorov s priamymi alebo skrutkovicovýmidrážkami po obvode, připadne iných tvarových otvorov.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for grouting holes with straight or helical grooves around the periphery, or other shape holes.
Doteraz sa leátenie otvorov s priamymi alebo skrutkovicovými drážkami po obvo-de prevádzalo elektrochemicky alebo mechanicky pomocou tvarového odliatku z olovaza použitia brúsnej pasty. Tiež známy mechanický spťjsob leStenia takýchto otvorovje kartáčováním pomocou ocelového kartáča, alebo takzvaným rámečkováním, kde sa leš-tia vždy len dve drážky nachádzajúce sa na priemere oproti sebe. Uvedené známe spo-soby leStenia otvorov s priamymi alebo skrutkovicovými drážkami po obvode sú pracnéa málo účinné, pričom elektrochemický sposob leStenia a mechanický pomocou tvaro-vého odliatku z olova sú zdraviu škodlivé.Until now, polishing holes with straight or helical grooves has been done electrochemically or mechanically using a molded lead casting using an abrasive paste. Also known is a mechanical brushing method of such openings by brushing with a steel brush, or by so-called framing, where only two grooves are located on the diameter opposite each other. Said known ways of fixing holes with straight or helical grooves around the circumference are laboriously inefficient, with the electrochemical method of mechanical and mechanical molding of lead being harmful to health.
Uvedené nedostatky odstraňuje nástroj na leštenie otvorov s priamymi aleboskrutkovicovými drážkami po obvode, pozostávajúci v tom, že tvarové nástrojovételeso je z elastického materiálu s obsahom brusivá a je svojim středovým otvoromnasunuté na upínacom trne s vonkajším závitom, na ktorom sú naskrutkované upínaciematice, medzi ktorými je upnuté toto nástrojové teleso. Koniec upínacieho trna jeotočné spojený s posuvnou týčou leštiaceho zariadenia. Výhodou nástroje na leštenie otvorov s priamymi alebo skrutkovicovými drážka-mi po obvode podlá vynálezu je jeho jednoduchá konštrukcia a výroba, vysoká účin-nost leStenia a značné velké životnost’. Tento nástroj rovnoměrně lešti ako otvor,tak aj všetky plochy drážok vrátane přechodových rádiusov naraz.The above-mentioned drawbacks are eliminated by a hole polishing tool with straight or helical grooves around the circumference, wherein the mold tool body is made of an abrasive-containing elastic material and is centered on the clamping mandrel with an external thread on which the clamping device is clamped between which it is clamped this tool body. The end of the clamping mandrel is rotatably coupled to the sliding bar of the polishing device. The advantage of the tool for polishing openings with straight or helical grooves around the periphery of the invention is its simple construction and manufacture, high efficiency of casting and considerable long service life. This tool evenly polishes both the hole and all groove surfaces, including transitional radii.
Na pripojenom výkrese je znázorněný příklad prevedenia nástroje na leštenieotvorov s priamymi alebo skrutkovicovými drážkami po obvode, ktorý je nakreslenýv náryse v řeze. Nástroj na leštenie 'podlá vynálezu pozostáva z tvarového nástrojového telesa1 zhotoveného Z elastického materiálu s obsahom brusivá. Sú to materiály z oblas-ti najma polymérnych plastických hmot například na báze polyolefínov, polyamidov,polyakrilátov, polyepoxidov s výhodou na báze polyuretánov, ktoré sa vyznačujú vy-sokou oderuvzdornosťou, variabilitou fyzikálno-mechanických vlastností a životnos-ťou. Typickým príkladom hmoty z tejto oblasti je mierne napěněný polyuretánovýelastomer bunečnej štruktúry v objemovej hmotnosti 500 až 1100 kg/m^, tvrdosti 50až 150 Sh (A) obsahujúci 40 až 120 % hmotových brusivá v pomere na polymernú hmotu.Toto tvarové nástrojové teleso 1_ sa vyrobí například odliatím do formy, pričom mo-že byť vyrobené s miernym presahom například vonkajšieho priemeru a rozmerov drá-žok. Tvarové nástrojové teleso 1 je v střede opatřené středovým otvorom 11, ktorýmje nasunuté na upínacom trne 7. opatřeným vonkajším závitom 21, na ktorom sú naskrut-kované upínacie matice 5., ktoré cez podložku 6 upínajú nástrojové teleso 1_ na upí-nacom trne £. Nástrojové teleso 1^ má na svojom valcovom povrchu vytvořené skrutko-vicové drážky 12 podlá tvaru leštenej súčiastky. Upínací trn £ je otočné uložený vpúzdre 2 prostredníctvom dvoch guličkových dráh _4, ktoré zároveň zabezpečujú totopúzdro .3 voči upínaciemu trnu proti axiálnemu posuvu. Púzdro _3 je zaskrutkovanév posuvnej tyči 7 leštiaceho zariadenia. Upínací trn £ je opatřený upínacími ploš-kami 22 pře doíahovanie alebo uvolňovanie upínacích matic 5,.The accompanying drawing shows an example of a straight or helical groove polishing tool having a circumferential outline drawn in cross-section. The polishing tool according to the invention consists of a shaped tool body 1 made of an elastic material containing abrasive material. They are materials of, in particular, polymeric plastics, for example based on polyolefins, polyamides, polyacrylates, polyepoxides preferably based on polyurethanes, characterized by high abrasion resistance, variability in physico-mechanical properties and durability. A typical example of a mass from this region is the slightly foamed polyurethane elastomer of the cell structure at a density of 500 to 1100 kg / m 2, a hardness of 50 to 150 Sh (A) containing 40 to 120% by weight of abrasive in proportion to the polymer mass. for example by casting into a mold, which may be produced with a slight overlap, for example, of the outer diameter and the dimensions of the grooves. The shaped tool body 1 is centrally provided with a central opening 11, which is mounted on a clamping mandrel 7 provided with an external thread 21, on which clamping nuts 5 are screwed, which clamp the tool body 7 on the clamping mandrel 6 via a washer 6. The tool body 1 has helical grooves 12 formed on its cylindrical surface 12 in the form of a polished component. The clamping mandrel is rotatably supported in the housing 2 by means of two ball tracks 4 which at the same time provide the sleeve 3 with respect to the clamping mandrel against axial displacement. The housing 3 is screwed in the sliding bar 7 of the polishing device. The clamping mandrel is provided with clamping surfaces 22 for tightening or releasing the clamping nuts 5,.
Tvarové nástrojové teleso _1 sa vsunie do otvoru so skrutkovicovými drážkami poobvode, pričom při vykonávaní priamočiareho vratného pohybu prostredníctvom posuv-nej tyče 7 kopíruje všetky skrutkovicové drážky v otvore, čím je zároveň natáčenév puzdre 2· Po opotřebení nástroje stačí pritiahnuť upínacie matice čím sa zvač-Sí priemer nástroje v rámci svojej pružnosti. Pri leštení nie je potřebné pridávaťThe shaped tool body 1 is inserted into the hole with helical grooves in the periphery, while in the rectilinear reciprocating movement by means of the sliding bar 7, it copies all the helical grooves in the opening, thereby also turning it in the housing 2. The diameter of the tool within its flexibility. It is not necessary to add when polishing
