Abstract

Tiahlo pohonu podávača je výkyvné uchy. tené pomocou čapu prestavitelného v drážke páky posúvajúcej pohyblivá klieštinu, pričom páka sa natáča okolo pevného čapu a pevná klieština slúži ako pevný doraz.The feeder drive rod is a pivoting handle. by means of a pin adjustable in the groove a lever moving the movable pliers, wherein the lever rotates around a fixed pin a solid pliers serve as a fixed stop.

Description

Predmetom vynálezu je klieštinový podávač s konšíantnou krajnou polohou pri rázných zdvihoch.The subject of the invention is a collet feeder with a constant end position at sharp strokes.

Sú známe klleštinové podávače, kde přesnost podávania je zaručená pevným dorazom. Pohyblivá klieština má kcnštantnú nulová polohu, odkial vykonává pohyb v horizontálnej rovině v kladnem a zápornom smere o velkosti polovice zvoleného kroku. Pre zaručenie přesnosti podávania medzi pevná a pohyblivá klieštinu zaradeuý prestavitel'ný doraz, ktorý pri každej zmene kroku podávania je nutné přestavit. Nevýhodou takého· zariadenia je to, že aby nedošlo k nepresnostiam podávania, je nutné doraz dimenzovat s ohladom na dynamické rázy, čo má za následok jeho mohutnost. Ďalšou nevýhodou klieštinového podávačů s konstantnou nulovou polohou je to, že prí malých krokoch podávania polotovar vykoná uieko ko krokov od pohyblivej klieštiny bez toho. aby ho pridržiavala pevná klieština. č;·· si vynucuje inštalovanie přídavného zariadenia na uchopenie polotovaru.Collet feeders are known where feed accuracy is guaranteed by a fixed stop. The movable collet has a constant zero position from where it moves in a horizontal plane in a positive and negative direction, half the size of the selected step. In order to guarantee the accuracy of the feed between the fixed and movable tongs, an adjustable stop is provided, which must be adjusted each time the feed step is changed. The disadvantage of such a device is that in order to avoid inaccuracies of feeding, the stop must be dimensioned with respect to dynamic shocks, which results in its robustness. A further disadvantage of constant zero position collet feeders is that in small feed steps the blank performs several steps away from the movable collet without it. to hold it tight. ··· forces the installation of an additional gripping device.

Tieto nevýhody do značnej miery zmierňuje zariadenie podl'a vynálezu, ktorého podstata spočívá v tom, že klieštinový podávač má konstantní! krajnú polohu. To je dosiahnuté tým, že tiahlo pohonu podávača je výPREDMETThese disadvantages are greatly mitigated by the device according to the invention, which is based on the fact that the collet feeder is constant. extreme position. This is achieved by the fact that the feeder drive rod is an object

Klieštinový podávač s konštantnou krajnou polohou při roznych zdvihoch obsahujúci pevná a pohyblivá klieštinu vyznačený tým, že tiahlo (1) jeho pohonu je výkyvné kyvné uchytené pomocou čapu prestaviteíného v drážke páky posúvajúcej pohyblivá klieštinu, pričom páka sa natáča okolo pevného čapu a pevná klieština slúži ako pevný doraz.Constant-limit collet feeder for various strokes comprising a fixed and movable collet, characterized in that the rod (1) of its drive is pivotally pivotally mounted by means of a pin adjustable in the lever groove of the movable collet, the lever pivoting like a fixed pin and fixed stop.

Příklad vyhotovenia zariadenia podía přihlášky vynálezu je na pripojenom obr. 1. Zariadenie sa skládá z páky 4 otáčajúcej sa ( kolo pevného čapu 5. Jedným koncom páka 4 zabezpečuje posuv pohyblivej klieštiny k pevnej klieštine 7, pričom jej náhon je zabezpečený tiahlom pohonu 1 výkyvné uchyteným pomocou čapu 2 přestavítelného v drážke 3, zariadenie pracuje následovně:An example of an embodiment of the device according to the invention is shown in FIG. 1. The device consists of a lever 4 rotating (fixed pin 5 wheel). One end of the lever 4 moves the movable collet to the fixed collet 7, its drive is secured by a traction drive 1 swiveled by a pin 2 adjustable in the groove 3. :

Klieštinový podávač má konštantnú krajná polohu pri roznych zdvihoch a mění sa nulová poloha, to znamená, že pohyblivá klieština S doráža v prednej krajnej polohe na pevnú klieštinu 7. Pri přestavení velkosti kroku klieštinového podávača sa uvolní čap 2 spájajúci tiahlo 1 pohonu s pákou 4.The collet feeder has a constant limit position on different strokes and the zero position is changed, i.e. the movable collet S arrives at a fixed collet 7 in the forward extreme position. Upon adjusting the size of the collet feeder step, the pin 2 connecting the drive rod 1 to the lever 4 is released.

V pálce 4, ktorá sa natáča okolo pevného čapu S pričom posúva pohyblivá klieštinu 6 je drážka 3 umožňujúca prestavenie čapu 2.In the bat 4, which pivots around the fixed pin S while moving the movable collet 6, there is a groove 3 for adjusting the pin 2.

V drážke 3 páky 4 sa čap 2 přestaví tak, aby krajná poloha pohyblivej klieštiny 6 bola na doraze o pevnú klieštinu 7.In the groove 3 of the lever 4, the pin 2 is adjusted so that the extreme position of the movable collet 6 is at the stop by a fixed collet 7.
