Sklučovadlo so súčasnou výměnou čelustiChuck with simultaneous jaw change

Vynález sa týká silovo ovládaného sklučovadla so súčasnou výměnou upínacích čelusti u ktorého sa rieši spoločný nosič čelusti.The invention relates to a force-operated chuck with simultaneous change of clamping jaws in which a common jaw carrier is provided.

Obdobné, doteraz známe riešenie sklučovadiel so súčasnou výměnou čelusti využivajú nosič, ktorý sa po ukončeni výměny čelusti odpája, nestává sa súčasťou sklučovadla, čo má za náaledok komplikované riešenie spojenia nosiča s čelusťami a potřebu zvláštneho manipulátora uskutočňujúcaho výměnu čelustí.A similar prior art solution of the jaws with simultaneous jaw change utilizes a carrier which is disconnected upon completion of the jaw change, which does not become part of the chuck, resulting in a complicated solution for connecting the jaw to the jaws and requiring a special jaw change manipulator.

Uvedené nevýhody sú zmiernané sklučovadlom so súčasnou výmanou čelusti, ktorého podstata spočívá v tom, že nosič čelusti sa po ukončení výměny čelusti stává súčasťou sklučovadla. Nosič čelusti sa ku sklučovadlu pripája prostredníctvom nesených čelusti, pričom samotný nosič a pružné tesnenie vložené medzi nosič a teleso sklučovadla zabezpečuje utesnenia vnútorného priestoru sklučovadla. Polohovanie čelustí na nosiči je zabezpečené polohovacím zariadením. Pre možnost automatickej výměny čelustí do Sklučovadla je nosič opatřený uchytóvačom pre chápadlo manipulátora alebo robota. Vhodná poloha nosiča čelustí a sklučovadla pre výměnu je daná dorazmi na telesa sklučovadla. Nosič čelusti slúži zároveň k pripevneniu exiálnych dorazov pre polohovanie upínaných obrobkov.These drawbacks are alleviated by a chuck with simultaneous jaw release, which is based on the fact that the jaw carrier becomes part of the chuck upon completion of the jaw change. The jaw carrier is attached to the chuck by means of supported jaws, wherein the carrier itself and the resilient seal inserted between the carrier and the chuck body provide a seal for the inner space of the chuck. The positioning of the jaws on the carrier is provided by a positioning device. For the possibility of automatic exchange of jaws into the chuck, the carrier is provided with a gripper for the gripper of the manipulator or robot. The suitable position of the jaw carrier and the chuck for replacement is given by the stops on the chuck body. At the same time, the jaw carrier serves to fasten the external stops for positioning the workpieces to be clamped.

Na připojených výkresoch je znázorněný příklad prevedenia vynálezu. Na obr. i je čelný pohled na nosič a polohovanim čeluate a umieatnenie axiélnych dorazov.An exemplary embodiment of the invention is shown in the accompanying drawings. In FIG. 1 is a front view of the carrier and positioning the face and location of the axial stops.

Na obr. 2 je nosič čelueti v raze ao schematicky znázorněným chápačom manipulátora, na obr. 3 je pohlad zhora na nosič a skZučovadlo před výměnou, na obr. 4 usporiadanie eklučovadle a nosiča po ukončeni výměny čaZuati a na obr. 5 js čelný pohlad na skZučovadlo bez nosiča.In FIG. 2 shows the carrier of the jaw in the punch and the handle of the manipulator shown schematically; FIG. 3 is a top view of the carrier and chuck prior to replacement; FIG. 4 shows the arrangement of the flocculant and the carrier upon completion of the replacement of the carpet and FIG. 5 is a front view of the chuck without carrier.

SkZučovadlo so súčasnou výměnou čelueti pozostáva z týchto hlavných čaeti: telesa nosiče 10, čelusti 20, telesa sklučovadla 30, uchytávača 40 a chápača manipulá tóra 50.The chuck with simultaneous jaw change consists of the following main members: carrier bodies 10, jaws 20, chuck bodies 30, gripper 40, and torah manipulator 50.

Na telese nosiča 10 sú známým spdsobom radiálně vedená čeluste 20 polohovaná odpruženými telieekami 21 čelueti 20, ktoré eú v zábere s vybraniami 13 telesa nosiča 10 tak, aby aa čeluete 20 dostali do záběru eo silovým mechanizmem 33 v telese sklučovadla 30. K teleeu nosiča 10 je připevněný uchytávač 40, ktorého poloha na telese nosiča 10 je fixovaná polohovacím telieskom 41. Uchytávač 40 má prispdeobená plochy 42 pre chápeč manipulátora 50, Podlá uplnacieho priemeru obrobku ea na teleso nosiča 10 alebo na uchytávač 40 naeadia axiálně dorazy 14. Pri výměna čelusti 20 do telesa sklučovadla 30 uchopí chápač manipulátora 50 uchytávač 40 a vsuňte čeluete 20 do teleea sklučovadla 30 tak, aby aa dostali do záběru ao silovým mechsniz mom 33. Táto polohe telesa nosiča 10 a telesa sklučovadla 30, kedy je možná čeluete v telese sklučovadla 30 známým spdsobom uzamknúť, je daná dorazmi 31.On the carrier body 10, the jaws 20 are positioned in a known manner by means of spring bodies 21 of the jaw 20, which engage the recesses 13 of the carrier body 10 so as to engage the ao jaws 20 with the force mechanism 33 in the chuck body. a gripper 40 is fixed, whose position on the carrier body 10 is fixed by a positioning body 41. The gripper 40 has adapted surfaces 42 for the gripper of the manipulator 50, depending on the workpiece fill diameter ea on the body 10 or on the gripper 40. into the chuck body 30, the gripper 40 grasps the gripper 40 and slide the jaws 20 into the chuck body 30 so as to engage and with a force mechanism 33. This position of the carrier body 10 and the chuck body 30 may face the chuck body 30 lock is given by stops 31.

K dokonalému utesneniu silového mechanizmu 33 ako i uzamykacieho mechanizmu 34 sú na telesa noaiča 10 vytvořené šikmé plochy 12 na stieranie nečistfit čelusti 20 pri ich eilovom pohybe. Ďalej je medzi teleeo noeiča 10 8 teleso sklučovadla 30 vložené teenenie 3,2. Teleeo nosiče 10 tvoři takto pomocou čelusti 20 kompaktný celok s telesom sklučovadla 30 a odnímá sa spolu s čeluaťaml 20 po obrobeni výrobnej dávky chápačom manipulátora 50.In order to perfectly seal the force mechanism 33 as well as the locking mechanism 34, sloping surfaces 12 are provided on the body of the wearer 10 for wiping off the jaws 20 as they move. Furthermore, a teenage 3.2 is inserted between the body of the carrier 10 8 and the chuck body 30. The carrier body 10 thus forms a compact unit with the chuck body 30 by means of the jaw 20 and is removed together with the jaws 20 after the production batch has been machined by the handle of the manipulator 50.

SkZučovadlo so súčaanou výměnou čelueti je vhodná pre jednotlivo naseděná sústružnlcke obrábacie centrá alebo pre eúetružnicke NC etroje naeadená do pružných výrobných systámov. Oeho zavadania umožňuje v spolupráci e manlpulátormi a s robotmi vylúčeníe obsluhy s technologického pracoviaka.SkClocker with coolant jaw change is suitable for single-mounted turning machining centers or for NC NC tools fitted into flexible manufacturing systems. The implementation of the problem in collaboration with e-manipulators and robots excludes the operator from the technologist.
