Abstract

Predmetom riešenia je montovaná klieština pozostávajúca z upínacích čelusti a vodiaceho krúžku. Jej podstata spočívá v tom, že upínacie čeXuste a vodiaci krúžok sú spojené rozoberatelne s plochými ramenami v jeden tuhý celok. Výhodou klieštiny je lahká vyměnitelnost čelusti po opotřebovaní a odolnost proti únavě.The subject of the solution is a mounted collet consisting of clamping jaws and a guide ring. Its essence lies in the fact that the clamping jaws and the guide ring are connected in a detachable manner with flat arms into one rigid unit. The advantage of the collet is easy replacement of the jaw after wear and fatigue resistance.

Description

Vynález sa týká klieštiny na upínanie rotačných, šesthranných a štvorhranných súčiastok, napr. ložiskových krúžkov, matic a pod. pri sústružení, brúsení a frézovaní.BACKGROUND OF THE INVENTION The invention relates to a collet for clamping rotary, hexagonal and square components, e.g. bearing rings, nuts and the like. for turning, grinding and milling.

Doteraz známe klieštiny na upínanie rotačných, šesthranných a štvorhranných súčiastok sa používali celistvé, vyrobené z jedného kusá materiálu. Tieto klieštiny vzhladom na svoju konštrukciu sú velmi náročné na výrobu a na spotřebu materiálu legovanéj ocele. Ďalšou nevýhodou póvodnych klieštin je náchylnost na vylomenie ramena z dóvodu klembového prierezu ramena, čo spósobuje nízku životnost klieštiny predčasnej únavy materiálu. Nízká životnost spósobuje zvýšenie nákladov na dalšiu výrobu klieštin pre plynulú prevádzku.So far known collets for clamping rotary, hexagonal and square parts have been used solid, made of one piece of material. Due to their construction, these collets are very demanding on production and on the consumption of alloy steel material. Another disadvantage of the pliers is the susceptibility to break off the arm from the back of the boom cross section, which causes a low lifetime of the premature fatigue pliers. The low lifetime results in an increase in the cost of further clamp production for continuous operation.

Uvedené nedostatky odstraňuje montovaná klieština podlá vynálezu, ktorej podstata spočívá v tom, že upínacie čeluste a vodiaci krúžok sú spojené rozoberatelne s plochými ramenami v jeden tuhý celok. Výhoda montovanej klieštiny podlá vynálezu spočívá v tom, že upínacie čeluste a pružné ramená sú po opotřebovaní vyměnitelné. Ďalej pružné ramená majú obdlžnikový prierez, ktorý je viaonásobne odolnější proti únavě a lomu, čim životnost klieštiny sa značné zvýši. Ďalšou výhodou je úspora materiálu cca 90 % a tým aj úměrná úspora pracnosti a zvýšenia produktivity práce pri výrobě klieštin. Příklad riešenia montovanej klieštiny podlá vynálezu je vyobrazený na připojených výkresoch. Obr. 1 znázorňuje nárys montovanej klieštiny pre upínanie obrobkov za povrch, šest, alebo štyri čeluste 2 a jeden vodiaci krúžok 2 sú spojené pevným spojom, ale rozoberatelne so šiestimi, alebo štyrmi plochými pružnými ramenami 2 v jeden celok. Obr. 2 znázorňuje pódorys klieštiny a obr. 3 znázorňuje rez klieštinou.The above-mentioned drawbacks are eliminated by the assembled pliers according to the invention, the principle of which is that the clamping jaws and the guide ring are connected detachably to the flat arms in one rigid assembly. The advantage of the assembled collet according to the invention is that the clamping jaws and the spring arms are replaceable after wear. Furthermore, the flexible arms have a rectangular cross-section that is more resistant to fatigue and fracture, the lifetime of the pliers being greatly increased. Another advantage is the material saving of about 90% and thus the proportionate saving of labor and increase of labor productivity in the production of pliers. An example of an embodiment of the assembled collet according to the invention is shown in the accompanying drawings. FIG. 1 shows a front view of the assembled workpiece clamp for the workpiece surface, six, or four jaws 2, and one guide ring 2 is joined together by a rigid joint but disassembled to six or four flat flexible arms 2 in one piece. FIG. Fig. 2 shows the podium of the collet and Fig. 3 shows the cross-section of the collet.

Montovaná klieština pracuje takto: upínacie čeluste 2 sa pri posúvaní v kuželovej dutině upinača sťahujú, alebo sa rozťahujú pomocou plochých pružných ramien 3, pričom vodiaci krúžok 2 zabezpečuje súosost a posuv klieštiny.The pre-assembled pliers operate as follows: the clamping jaws 2, when moved in the conical cavity of the clamp, extend or extend by means of flat spring arms 3, wherein the guide ring 2 ensures the coil alignment and movement.
