Predmetom vynálezu je zariadenie na nastavenie polohy plynule prestavitelných če1’ustí sklučovadla najma pre NC stroje. U doteraz známých sktučovadiel sa poloha plynule prestavitelných čelustí nastavuje samostatné, připadne súčasne a to ručně, pri použití róznych nóniusov, připadne zvláštnymi k tomu účelu vytvořenými prestavovaco-odmeriavacími zariadeniami. Tento úkon je v prvom případe časové náročný a v značnej miere závisí od zručnosti a pozornosti zoraďovača. V případe použitia zvláštnych prestavovaco-odmeriavacích zariadení, sa značné zvyšujú náklady na upínací systém na jednej straně a na straně druhej, sa samotný NC stroj doplňuje obyčajne o další prestavovaco-odmeriavací systém, čím sa komplikuje i riadenie činnosti NC stroja. Jeden prestavovaco-odmeriavací systém u NC stroja sa využívá už na změnu polohy nástroja. Po (nastavení polohy čelustí sa potom obyčajne uskutočňuje další, súčasný pohyb čelustí za účelom upínania súčiastky.
Uvedené nevýhody sú zmiernené zariadením na nastavenie polohy plynule prestavitelných čelustí sklučovadla, ktorého podstata spočívá v tom, že polohovacie zariadenie je vybavené polohovacím telesom s dorazovou plochou usporiadanou proti dorazovej ploché upínacej čeluste sklučovadla.
Zariadením na nastavenie polohy čeluste sklučovadla sa jednak vylúči nepřesnost nastavenia čelustí ovplyvnená človekom, jednak skráti čas nastavenia čelustí, vylúči sa. samostatný nastavovaco-odmeriavací systém na prestavenie čelustí, nakolko je žiadúce sledovat len okamih dorazu čeluste.
Zariadenie podlá vynálezu umožní velmi jednoduché nastavenie čelustí u moderných strojov a pri necentrickom upínaní nastavenia požadovanej excentricity pre dalšie súčasné prestavovanie alebo silové upínanie.
Na pripojenom výkrese je znázorněný příklad zariadenia na nastavenie polohy čelustí sklučovadla v bočnom pohlade podlá vynálezu.
Zariadenie pozostáva z polohovacieho zariadenia 300, realizovaného napr. ako suport sústružníckeho stroja 100, připadne ako rameno robota, s držiakom 320 polohovacieho telesa 310. Pri nastavovaní polohy upínacej čeluste 210 dorazová plocha 312 polohovacieho telesa 310 sa polohovacím zariadením 300, pomocou jeho prestavovacieho mechanizmu, například skrutky suportu, nastaví v smere šípky radiálneho směru „b“, na vzdialenosť R od osi sklučovadla O a v smere šípky axiálneho směru „a" k čelu polohovaného sklučovadla, ktorého upínacie čeluste 210 sa nachádzajú v referenčnej polohe danej například ich vonkajšou krajnou polohou v radiálnom vedení telesa sklučovadla 200. Vzdialenosť R je daná súčtom polomerov upínaného, například obrobku a časti například polovice silového zdvihu upínacej čeluste 210 sklučovadla, čo umožňuje na jednej straně vloženie obrobku medzi upínacie čeluste 210 a na straně druhej aj jeho silové upnutie bez vyčerpania celého silového zdvihu upínacej čeluste 210. Dorazová plocha 312 polohovacieho telesa 310 je v nastavenej polohe usporiadané oproti dorazovej ploché 213 upínacej čeluste 210. Sklučovaďo 200 je známého prevedenia, například so základnými čelusťami 220 a upínacími čelusťami 210, medzi ktorými je známým sposobom uložená pohybová skrutka 221. Jej otáčaním například pohonnou jednotkou 400, ktorou móže byť i pohon samotného vřetena stroja, (zasunutím jej ovládacieho klúča 321 do ovládacieho zahíbenia 224 pohybovej skrutky 221} sa radiálně presúva upínacia čelusť 210 k polohovaciemu telesu 310 polohovacieho zariadenia 300 až do polohy, kým dorazová plocha 213 upínacej čeluste 210 nedorazí o dorazovú plochu 312 polohovacieho telesa 310 polohovacieho zariadenia 300. V tejto polohe sa prestavenie upínacej čeluste 210 zablokuje například vypnutím pohonnej jednotky 400 prepojenej s niektorým zo známých elektrických snímačov registrujúceho například preklznutie trecej spojky pohonnej Jednotky 400. V případe, ked pohonná jednotka 400 bude například rotačný hydromotor, jej vypnutie sa móže uskutočniť i elektrickým tlakovým spínačom známého prevedenia po dosiahnutí blokovacieho tlaku v ovládacom obvode po dorazeni upínacej čeluste 210 o polohovacie teleso 310.
Zariadenie je s výhodou použitelné například pri karuselovom upínaní, připadne v automatizovaných technologických pracoviskách, i s priemyselným robotom.
The solution relates to a device for adjusting the position of continuously adjustable chucks.
The essence of the device is that the machine positioning device is provided with a positioning body with a stop surface arranged opposite the stop flat clamping jaw of the chuck.
The jaw positioning device eliminates the need for a separate displacement metering device to increase the accuracy of the setting and, at the same time, the metering devices provided by the machine can be used to adjust the jets.

The object of the invention is a device for adjusting the position of continuously adjustable chucks for NC machines. In the so-called liquefiers known so far, the position of the continuously adjustable jaws is set separately, at the same time by hand, with the use of various nannies, or by special displacement gauges created for this purpose. This action is time consuming in the first instance and greatly depends on the skill and attention of the shifter. In the case of the use of special displacement gauges, the cost of the clamping system is considerably increased on the one hand, and the NC machine itself is usually supplemented by another displacement-metering system, thereby complicating the control of the NC machine. One adjusting / measuring system for the NC machine is already used to change the tool position. After (the positioning of the jaws is then usually carried out a further, simultaneous movement of the jaws to clamp the component.
These disadvantages are alleviated by the positioning device of the continuously adjustable chuck jaws, which is characterized in that the positioning device is provided with a positioning body with a stop surface arranged opposite the stop flat clamping jaw of the chuck.
On the one hand, the device for adjusting the position of the chuck jaw eliminates the inaccuracy of the adjustment of the jaws affected by the man, and on the other hand shortens the setting time of the jaws, eliminates it. a separate adjusting-metering system for adjusting the jaws as it is desirable to monitor only the moment of the jaw stop.
The device according to the invention allows very simple adjustment of the jaws in modern machines and in the non-centric clamping of the desired eccentricity setting for further simultaneous adjustment or force clamping.
BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawing, an example of an apparatus for adjusting the jaw position of a chuck in a side view of the invention is shown.
The device consists of a positioning device 300, implemented, for example, as a support of a turning machine 100, or as a robot arm, with a holder 320 of the positioning body 310. When adjusting the position of the clamping jaw 210, the stop surface 312 of the positioning body 310 with the positioning device 300, by its adjusting mechanism, for example, the slide bolts, adjust in the direction of the arrow in the radial direction "b", the distance R from the axis of the chuck O and in the direction of the arrow the axial direction "a" to the face of the positioning chuck, whose clamping jaws 210 are in a reference position given, for example, by their outermost position in the radial guide of the chuck body 200. The distance R is given by the sum of the clamping radii, for example of the workpiece and the part, for example, of the chuck clamping jaw 210, which allows the insertion of the workpiece between the clamping jaws 210 and its clamping force on the other hand The end face 312 of the positioning body 310 is disposed in a set position relative to the stop flat 213 of the clamping jaw 210. The chuck 200 is a known embodiment, for example with base jaws 220 and clamping jaws 210, among which is known method a moving screw 221. It is rotated, for example, by the drive unit 400, which can also drive the machine spindle itself (by inserting its actuating key 321 into the actuating nip 224 of the movement screw 221}, the clamping jaw 210 moves radially to the positioning body 310 of the positioning device 300 up to the stop surface 213 of the clamping jaw 210 does not reach the stop surface 312 of the positioning body 310 of the positioning device 300. In this position, the adjustment of the clamping jaw 210 is locked, for example, by switching off the drive unit 400 connected to any of the known electric If the drive unit 400 is, for example, a rotary hydraulic motor, its shutdown can also be effected by an electric pressure switch of a known design after reaching the locking pressure in the actuating circuit after the clamping jaw 210 has reached the positioning body 310 .
The device is useful for example in carousel clamping, in automated technological workplaces, as well as industrial robots.
