Vynález sa týká oboru manipulácie súčiastok s otvorom. Vynález rieSi uchopovanie a prenááenie súčiastok s otvorom. Podstatou vynálezu je, že je tvořený nosnou týčou pevne uchytenou na telese uchopovača. Na nosnej tyči je posuvné a odpružené uložené ovládaeie púzdro, ktoré je posuvné uložené v telese uohopovača v obmedzenej dížke. Dolný koniec nosnej tyče je výkyvné opatřený upínacím zasahujúcim cez otvor ovlédacieho puzdra nad jeho povrch. Horný koniec ovlédacieho puzdra je opatřený obvodovou drážkou, oproti ktorej je v telese uchopovača výkyvné uložená poistná páka, na ktorej činné rameno dosadá přítlačná pružina. Vynález najlepšie charakterizuje abr.č. 1The invention relates to the field of handling parts with a hole. The invention solves the gripping and transferring of parts with a hole. The essence of the invention is that it is formed by a support rod firmly attached to the gripper body. On the support rod is a sliding and spring-loaded control sleeve, which is slidably mounted in the gripper body in a limited length.

Vynález sa tyká zhotovenia uchopovača na prenášanie, alebo zakladenie súčiastok sotvorom. / Při montáži výrobkov vzniká potřeba, tvarové a hmotnostně odlišné aúčiastky, pré-mie stňovat z miesta odoberanla do miesta zakladenia. Sú známe zariadenia, kde uchopenlesúčiaetky je odvodené od vačkových mechanizmov připadne excentrov, které zabezpečuji! po-žadovaná echému pohybov. Sú známé jedno a viacúčelové uchopovacie zaradenla,které vyhovu-jú roznym požiadavkam rovnakého, alebo podobného druhu uchopovanéj sáčiastky.The invention relates to the construction of a gripper for carrying or inserting parts with an opening. (When assembling the products, there is a need for molded and different weight parts, and it is rather necessary to place it from the place where it is removed to the place of loading). Devices are known, where the gripper is derived from cam mechanisms to the eccentric that I provide! required echo movements. Single and multipurpose gripping devices are known which meet the same requirements of the same or similar kind of gripped part.

Spoločnou nevýhodou uvedených zariadenl je leh velká rozmarnost, Čo je sposobené tým,že každý druh pohybu má samostatný zdroj pohonu, ktorý sa musí podlá Specifických podmie-nok riadit. Nevýhodou je aj náročnéjáia údržba týchto zariadenl.A common disadvantage of said devices is the great whimsicalness which is caused by the fact that each kind of movement has a separate drive source which has to be controlled according to the specific conditions. The disadvantage is also the demanding maintenance of these devices.

Vyššie uvedené hevýhody zmiernuje uchopovač súčiastok s otvorom podlá vynálezu, kto-rého podstatou je, že je tvořený nosnou týčou pevne úchytenou na teleee uchopovača. Na nosnej tyči je posuvné a odpružené uložené ovládacie puzdro, které je posuvné uložené v tele-ee uchopovača v obmedzenej dlžke prostrednictvom dorazového kolíka. Dolný koniec nosnejtyče je výkyvné opatřený upínacím palcom zasahujúcim cez otvor ovládacieho puzdra nad je-ho povrch. Horný koniec ovládacieho puzdra je opatřený obvodovou drážkou, oproti ktorejje v teleee uchopovača výkyvné uložená poistná páka, na ktorú dosadá přítlačná pružina.The aforementioned disadvantages are alleviated by the gripper of the opening parts of the invention, which is essentially formed by a support rod fixedly attached to the gripper body. On the support rod there is a sliding and spring-mounted control housing which is slidably mounted in the gripper body in a limited length by means of a stop pin. The lower end of the support rod is pivotably provided with a clamping thumb extending over the opening of the control housing over its surface. The upper end of the actuating sleeve is provided with a circumferential groove, opposite to which a locking lever is pivotably mounted on the gripper body, on which the pressing spring abuts.

Uchopovačom súčiastok s otvorom sa docieli uchopovat aúčiastky rožnej velkosti, hmot-nosti a tvarovéj členitosti, pretože na uchopenle stačí keá sú v tažisku alebo v blízkostiťažiska opatřené otvorom prisposobeným hmotnosti aúčiastky. Zariadením je možné uchopovat a přenášet výrobky z umělých hmot a výrobky nemagnetické. Výhodou uchopovača je aj jehojednoduchost a apolahlivSet jeho prevádzky.With the gripper of the opening parts, it is possible to grip and grip parts of size, weight and shape rupture, since the grip is sufficient to be provided with a weight and component aperture in the center of gravity or in the center of gravity. It is possible to grip and transfer plastic products and non-magnetic products with the device. The advantage of the gripper is its simplicity and its operation.

Na připojených výkresoch je znázorněné příkladné prevedenie uchopovača, kde na obr.lje nakreslený uchopovač v poždlžnom řeze před uchopením súčiaetky, na obr. 2 je nakresle-ný uchopovač v pozdlnom řeze s uchopenou súčiastkou a na obr.3 je nakreslený rez rovinouA - A z obr. 1.In the accompanying drawings, an exemplary embodiment of a gripper is shown, wherein in FIG. 1 a gripper is drawn in a longitudinal section prior to gripping a part, in FIG. 2 a gripper is drawn in a longitudinal section with a gripped part and in FIG. Fig. 1.

V telese 1 uchopovača je pevne uložený dorazový kolík 10 zasahu-júci do vodiacej drážky 18 vytvorenej v ovládacom puzdre 2. Horný koniec ovládacieho puzd-ra 2, je opatřený obvodovou drážkou 6. Oproti obvodovej drážke 6 je v drážke telesa 1 ucho-povača výkyvné uložená na čapě 12 poistná páka 4, na ktorej činné rameno dosadá přítlačnápružina 2 pevne uchytená skrutkou 13. na telese 1 uchopovača. V telese 1 je pevne prostřednictvom válcového kolika 11 uložená nosná tyž 2» pričom v ovládacom puzdre 2 je nosná tyči uložená vsuvne. Na dolnom konci nosnej tyče 2 je vo vidlici 14 výkyvné uložený na valco-vom čapě 15 upínací palec 8, ktorý zasahuje cez otvor 9, ovládacieho puzdra 2 nad jeho po-vrch. Dolný koniec ovládacieho puzdra 2 je opatřený zátkou 17 prostrednictvom kolika 16.Medzi zátkou 17 a čelom nasnej tyče 2 j® uložená tlačná pružina 2· Horný koniec nosnej ty-če 2 j® opatřený upínacpu vidlicou 20.A component gripper with an opening consisting of a body 1 in which a control sleeve 2 is slidably mounted. A stop pin 10 engaging a guide groove 18 formed in the actuating sleeve 2 is fixedly mounted in the gripper body 1. The upper end of the control sleeve -a 2 is provided with a circumferential groove 6. In contrast to the circumferential groove 6, a locking lever 4 is pivotally mounted on the pivot 12 in the groove of the gripper body 1, on which the actuating arm engages the pressure spring 2 fixedly by the screw 13. on the gripper body 1. A support rod 2 is fixedly supported by the cylindrical pin 11 in the body 1, and the support rod 2 is slidably inserted in the control housing 2. At the lower end of the support rod 2, in the fork 14, a clamping thumb 8 is mounted on the cylindrical pin 15, which extends over the opening 9 of the control sleeve 2 above its top. The lower end of the control sleeve 2 is provided with a plug 17 through the pin 16. A compression spring 2 is provided between the plug 17 and the nose of the nasal rod 2, the upper end of the support rod 2 is provided with a fork clamp 20.
