Description

Przedmiotem wynalazku jest samocentrujacy uchwyt tokarski sluzacy do recznego mocowania przedmiotów na obrabiarce.W znanych rozwiazaniach tego typu uchwytów pierscien napedowy szczek mocujacych jest ustalo¬ ny w korpusie uchwytu za pomoca pokryw jak to jest uwidocznione w opisach patentowych RFN nr 930910 i nr 1159239, lub czopów napedowych stozkowych kólek zebatych, które przytrzymuja go bezposrednio swoja czescia trzpieniowa albo za posrednictwem tulejek nasadzonych na czopy, czy tez jako czesc dystansowa sluzy pierscien wspól- srodkowy z pierscieniem napedowym wedlug roz¬ wiazan opisanych w opisie patentowym polskim nr 1807.Celem wynalazku jest opracowanie takiej kon¬ strukcji uchwytu, która umozliwialaby bardzo do¬ kladne ustalenie pierscienia napedowego, niemozli¬ we w dotychczas znanych rozwiazaniach, jedno¬ czesnie w sposób ekonomiczny zabezpieczajac po¬ krywa mechanizmy napedowe szczek uchwytu.Cel ten osiagnieto opracowujac samocentrujacy uchwyt tokarski, w którym pierscien napedowy jest ustalony poosiowo plytkami oporowymi, które jed¬ nym koncem znajduja sie w jego wytoczeniu, zas pozostala czescia umieszczone w poglebionych miej¬ scowo prowadnicach szczek, zas pokrywa i plytki oporowe sa polaczone srubami umieszczonymi w korpusie uchwytu. 10 15 25 30 Przedmiot wynalazku jest przedstawiony w przy¬ kladzie wykonania na rysunku, na którym fig. 1 przedstawia uchwyt w przekroju, zas fig. 2 — widok uchwytu z czola po wyjeciu szczek mocujacych.Uchwyt posiada korpus 1 w którego poglebionych miejscowo prowadnicach 2 szczek mocujacych 3 sa umieszczone plytki oporowe, 4 które jednym koncem znajduja sie w wytoczeniu 5 pierscienia napedowego 6.Plytki oporowe 4 sa polaczone z pokrywa 7 sru¬ bami 8 umieszczonymi w otworach korpusu 1 uchwytu. Z pierscieniem napedowym 6 sa zazebio¬ ne stozkowe kólka zebate 9 powodujace przy recz¬ nym ich pokrecandu przesuw szczek mocujacych 3.Opracowana konstrukcja umozliwia bardzo do¬ kladne ustalenie odleglosci przy zazebianiu pier¬ scienia napedowego 6 ze szczekami mocujacymi 3 przy jednoczesnym najkorzystniejszym zazebianiu ze stozkowymi kólkami zebatymi 9. Wynalazek eli¬ minuje dotychczasowe wady szczególnie w precy¬ zyjnych uchwytach saimocentrujacych, gdzie nie¬ wielka nawet róznica przy wspólpracy szczek mo¬ cujacych 3, pierscienia napedowego 6 i stozkowych kólek zebatych 9 wplywa w istotny sposób na uzy¬ skiwane dokladnosci ich pracy. Jednoczesnie roz¬ wiazanie umozliwia stosowanie lekkich i gladkich pokryw 7, które dotychczas byly klopotliwe w wy¬ konaniu, poniewaz aby przytrzymywac pierscien napedowy 6 musialy posiadac wybrania na stozko¬ we kólka zebate 9. 133 216133 216 Zastrzezenie patentowe Samocentrujacy uchwyt tokarski, którego szczeki mocujace poruszane sa za pomoca pierscienia na¬ pedowego posiadajacego z jednej strony nacieta spirale, zas zd rugiej uzebienie sprzegniete ze stoz¬ kowymi kólkami zebatymi, znamienny tym, ze pierscien napedowy (6) jest ustalony poosiowo plyt¬ kami oporowymi (4), które jednym koncem znaj¬ duja sie w jego wytoczeniu (5), zas pozostala cze¬ scia sa umieszczone w poglebionych miejscowo pro¬ wadnicach (2) szczek mocujacych (3) oraz ze po¬ krywa (7) i plytki oporowe (4) sa ze soba polaczo¬ ne srubami (8) umieszczonymi w otworach korpu¬ su (1) uchwytu.Fig.;.Fig. 2. 9_ 5 3 6/1 7 8 2 PZGraf. Koszalin. A-2013 lOfr A-4 Cena 100 zl PLThe subject of the invention is a self-centering lathe chuck for manual clamping of workpieces on a machine tool. Known solutions of this type of chuck, the drive ring of the clamping jaws is fixed in the chuck body by means of covers, as it is shown in German patents No. 930910 and No. 1159239, or on pins. drive conical toothed wheels, which hold it directly with its spindle part, either by means of sleeves placed on the pivots, or as a spacer part, the center ring with the drive ring serves as a solution according to the solutions described in Polish patent description No. 1807. a chuck structure that would allow a very precise positioning of the drive ring, impossible in the previously known solutions, while at the same time protecting economically and covering the drive mechanisms of the chuck jaws. This goal was achieved by developing a self-centering lathe chuck in which the The hinge is axially fixed with stop plates, which at one end are in its groove, and the remaining parts are placed in locally deepened jaw guides, while the cover and stop plates are connected by screws placed in the handle body. The subject of the invention is presented in an exemplary embodiment in the drawing, in which Fig. 1 shows the handle in cross section, and Fig. 2 - a view of the handle from the front after removing the fastening jaws. The handle has a body 1 in which guides 2 are deepened locally The clamping jaws 3 are fitted with stop plates 4 which at one end are in the recess 5 of the drive ring 6. The stop plates 4 are connected to the cover 7 by screws 8 placed in the openings of the body 1 of the handle. The drive ring 6 has toothed conical toothed wheels 9, causing the clamping jaws 3 to move with their manual turning. with toothed wheels 9. The invention eliminates the disadvantages to date, especially in precision self-centering chucks, where even a small difference in the cooperation of the fixing jaws 3, the drive ring 6 and the conical gear wheels 9 significantly affects the accuracy of their work. At the same time, the solution makes it possible to use light and smooth covers 7, which so far have been difficult to manufacture, because in order to hold the drive ring 6, they had to have recesses for taper toothed wheels 9. 133 216 133 216 Claim. Self-centering lathe chuck with clamping jaws They are moved by a drive ring with grooved spirals on one side, and by a tooth on the other side coupled with conical toothed wheels, characterized by the fact that the drive ring (6) is axially fixed with stop plates (4), which at one end are located in its groove (5), and the rest of the parts are placed in locally deepened guides (2) of the clamping jaws (3) and that the cover (7) and the stop plates (4) are connected to each other By means of screws (8) placed in the holes of the body (1) of the handle.
