Abstract

Vynález sa týká upínacieho sktučovadla umožňujúceho výměnu četustí z čela skl'učovadla rovnoběžně s osou sktučovadla pomocou nove) úpravy, zabudováním vytláčacieho zariadenia do telesa sklučovadla, ktorého akčný člen je v zábere s vyměnitelnými prvkami, pozostávajúcich z čelustí a nosiča čelustí.The invention relates to a chuck enabling the exchange of jaws from the chuck face parallel to the chuck axis by means of a novel arrangement, incorporating an extrusion device into the chuck body, the actuator of which is in engagement with replaceable elements consisting of jaws and a jaw carrier.

Description

Predmetom vynálezu je upínacie sklučovadlo s výměnou čelustí z čela sklučovadla pozostávajúce zo základného telesa s radiálnymi vybraniami v čele sktučovadla, z čelustí umiestnených na nosiči čelustí, kde sa rieši výměna čelustí.The object of the invention is a chuck with a jaw change from a jaw face consisting of a base body with radial recesses at the jaw face, of jaws located on the jaw carrier, where jaw change is solved.

Obdobné doteraz známe riešenia sktučovadiel so súčasnou výměnou čelustí využívajú nosič, ktorý sa po ukončení výměny odpája, nestává sa súčasťou sktučovadla, alebo používajú nosič s čelusťami, kde po výměně čelustí nosič čelustí sa stává súčasťou čelustí. K výměně čelustí je potřebný zvláštně upravený manipulátor pre vyberanie nosiča čelustí zo sklučovadla, najma z toho důvodu, že dochádza k zaklíneniu čelustí v telese sklučovadla.Similar prior art solutions of jaws with simultaneous jaw change utilize a carrier which is disconnected upon completion of the jaw change, does not become part of the jaws, or use a jaw carrier where jaw carrier becomes part of jaws after jaw change. A special manipulator is required to replace the jaws to remove the jaw carrier from the chuck, in particular because the jaws are wedged in the chuck body.

Uvedené nedostatky sú zmiernené riešením upínacieho sklučovadla podlá vynálezu, ktorého podstata spočívá v tom, že v základnom teleše je zabudované aspoň jedno vytláčacie zariadenie, ktorého akčný člen spoluzaberá s aspoň jedným vyměnitelným prvkom. Zdvih akčného člena vytláčacieho zariadenia v základnom teleše je nastavitelný.These drawbacks are alleviated by the solution of the chuck according to the invention, which is characterized in that at least one extrusion device is incorporated in the base body, the actuator of which cooperates with at least one exchangeable element. The stroke of the actuator actuator in the base body is adjustable.

Upínacím sklučovadlom podlá vynálezu sa zjednodušuje výměna čelustí z čela sklučovadla, výměnu može previesť jednoduchý manipulátor alebo robot pre výměnu obrobkov.The clamping chuck according to the invention simplifies the replacement of the jaws from the chuck face, the replacement can be carried out by a simple manipulator or a robot for changing workpieces.

Na pripójenom výkrese je znázorněný příklad prevedenia upínacieho sklučovadla podlá vynálezu. Na obr. 1 je znázorněné sklučovadlo v čelnom pohlade, na obr. 2 je znázorněné v čiastočnom osovom řeze sklučovadlo a příklad prevedenia vytláčacieho zariadenia podlá vynálezu.The accompanying drawing shows an example of an embodiment of a chuck according to the invention. In FIG. 1 is a front view of the chuck; FIG. 2 shows a partial axial section of a chuck and an example of an embodiment of an extruder according to the invention.

Upínacie sklučovadlo pozostáva z týchto hlavných častí: teleso sklučovadla 10, vyměnitelné prvky 20, ktoré pozostávajú z če-The chuck consists of the following main parts: chuck body 10, replaceable members 20, which consist of a chuck.

Claims

OBJECT

Clamping chuck with a change jaw of a face consisting of a base body, a jaw actuating body, a radial guide of the jaws adjustable in the base body, of replaceable elements comprising at least jaws and a jaw carrier, characterized in that the base body (10) at least one of the jaws 22 and the jaw carrier 21 and of the extruder 30 are incorporated. The operation of the jaws 22 is converted by a known kinematic chain method. The body of the chuck 10 and the claw 22 are adapted to replace the jaws 22 from the face, as shown, for example, in MS. Patent AO No. 218 722. The movable guiding of the jaws is converted by a known method, such as that shown in MS. The extruder 30 is disposed in the body of the chuck 10. The extruder 30 comprises the following components: actuator 31, adjusting screw 32, regulating screw 33, spring 34. Position of replaceable elements 20 in the chuck body 10 in the axial direction is determined by the stop 11 located in the body of the chuck 10. The actuator 31 of the extruder 30 is engaged with the carrier by the jaw 21. After the movable guide has been moved to the replacement position 20, the actuator pushes the carrier axially out of the chuck body 10 and allows the jaws 22 to be exchanged with the jaw carrier 21 via a simple workpiece manipulator. The adjusting screw 32 adjusts the axial stroke of the actuator 31 of the extruder 30. The adjusting screw 32 allows the axial force of the actuator 31 to be adjusted by the spring 34 so that the value of the axial force is in accordance with the axial force exerted by the replaceable element manipulator. The clamping chuck of the present invention allows reliable replacement of the jaws in an automatic cycle without operator intervention even when jaws jam in the chuck body. A simple manipulator can convert the jaws. A pressing device (30) is provided, the actuator (31) of which engages at least one replaceable element (20).

Clamping chuck according to claim 1, characterized in that the axial stroke (a) of the actuator (31) of the extruder (30) in the base body (10) is adjustable. 2 sheets of drawings 237137
