Abstract
Účelom vynálezu je vyvodenie potrebnej prítlačnej sily pre upnutie obrobku a vytvorenie elektricky vodivého spoja medzi obrobkom a upínacím zariadením. Uvedeného účelu sa dosahuje vynálezom, ktorého podstatou je, že upínacie zariadenie je tvořené tlačným pružným členom medzi pracovným nástrojem a hrncovitým obrobkom.The purpose of the invention is to generate the necessary pressing force for clamping the workpiece and to create an electrically conductive connection between the workpiece and the clamping device. The stated purpose is achieved by the invention, the essence of which is that the clamping device is formed by a pressing elastic member between the working tool and the pot-shaped workpiece.
Description
Vynález sa týká riešenia upínacieho zariadenia najma hrncovitých obrobkov na elektrochemických obrábacích strojoch, například pri odhrotovaní.The invention relates to a solution of a clamping device, in particular of pot-shaped workpieces, on electrochemical machine tools, for example during deburring.
Přívod elektrického prúdu na elektrochemicky obrábané obrobky je v súčasnosti riešený tak, že sa kontaktně plochy obrobku a elektricky kladné nabité plochy příslušenstva obrábacieho zariadenia k sebe pritláčajú prostredníctvom páky, podložky a skrutky, ktorá vyvodzuje potrebnú silu. Tento spósob upínania vyhovuje vtedy, ak strojný čas obrábania rje podstatné dlhší, ako čas upínania a ak na kontaktnú plochu obrobku je možné pri obrábaní oprieť koniec prítlačnej páky. Pri odhrotovávaní hrncovitých obrobkov, například s čelným ozubením nie je splněná ani jedna z uvedených požiadaviek.The power supply to the electrochemically machined workpieces is currently designed so that the contact surfaces of the workpiece and the electrically positive charged surfaces of the machine tool accessories are pressed together by means of a lever, a washer and a bolt which applies the necessary force. This clamping method is suitable if the machining time r is substantially longer than the clamping time and if the end of the pressure lever can be supported on the workpiece contact surface during machining. Neither of the above requirements is met when deburring pot-shaped workpieces, for example with spur gearing.
Vyššie uvedený problém upínania najma hrncovitých obrobkov na elektrochemických obrábacích strojoch rieši upínacie zariadenie elektrochemicky obrábaných najma hrncovitých obrobkov podl'a vynálezu, ktorého podstatou je, že je tvořené tlačným pružným členom, uloženým medzi pracovným nástrojom a hrncovitým obrobkom.The aforementioned problem of clamping particularly pot-shaped workpieces on electrochemical machine tools is solved by a clamping device of electrochemically machined particularly pot-shaped workpieces according to the invention, which is constituted by a compression spring member disposed between the working tool and the pot-shaped workpiece.
Upínacím zariadením podlá vynálezu sa docieli elektrochemicky obrábať, hlavně odhrotovávať hrncovité obrobky. Vynález umožňuje znížiť čas upínania, čo má význam najma v prípadoch, u ktorých je krátký čas obrábania.The clamping device according to the invention achieves electrochemical machining, in particular deburring of pot-shaped workpieces. The invention makes it possible to reduce the clamping time, which is particularly important in cases where the machining time is short.
Na pripojenom výkrese je znázorněné příkladné riešenie upínacieho zariadenia elektrochemicky obrábaných hrncovitých obrobkov, kde je nakreslené v řeze.The attached drawing shows an exemplary solution of a clamping device of electrochemically machined pot-shaped workpieces where it is drawn in cross-section.
Upínacie zariadenie pozostáva z tlačného pružného člena 5, tvořeného tlačnou pružinou, ktorá je uložená jedným koncoim vo vyústění 4 pracovného nástroja 1 a druhým koncom na podložke 11 uloženej na elektroizolačnej vložke 10 ustavenej strediacim kolíkom 9 na dne hrncovitého obrobku ífi. Vonkajším povrchom je hrncovitý obrobok 6 uložený na upínacej doske 7 elektrochemického obrábacieho zariadenia (na obr. nezakreslenom) v elektroizolačnom ustavovacom krúžku 8. Na dolnej ploché pracovného nástroja 1 je vytvořená činná časť 2. Na vyústenie 4 pracovného nástroja 1 je připojený prívodný kanál 3 elektrolytu. Pracovný nástroj 1 je připojený na záporný pól zdroja elektrického prúdu a na hrncovitý obrobok 6 je připojený kladný pól zdroja elektrického prúdu (na obr. nezakreslené).The clamping device consists of a compression spring member 5 formed by a compression spring which is supported by one end in the opening 4 of the working tool 1 and the other end on a support 11 mounted on the insulating insert 10 set by a centering pin 9 on the bottom of the pot. The outer surface is a pot-shaped workpiece 6 mounted on a clamping plate 7 of an electrochemical machine tool (not shown in the drawing) in an electrical insulating locating ring 8. A working part 2 is formed on the lower flat working tool 1. The electrolyte supply channel 3 is connected to the outlet 4 of the working tool 1. . The working tool 1 is connected to the negative pole of the power supply and to the pot-shaped workpiece 6 is connected to the positive pole of the power supply (not shown in the figure).
Po spustení elektrochemického obrábacieho zariadenia sa začne prisúvať pracovný nástroj 1 k hrncovitému obrobku 6, čím sa zároveň stláča tlačná pružina 5, ktorou sa vyvodzuje dostatočná přítlačná sila jednak na upnutie hrncovitého obrobku 6 na upínacej doske 7 a jednak sa zabezpečuje potřebný přítlačný tlak pre přívod prúdu.After starting the electrochemical machine, the working tool 1 begins to be pushed towards the pot-shaped workpiece 6, thereby simultaneously compressing the compression spring 5, which exerts a sufficient contact force to clamp the pot-shaped workpiece 6 on the clamping plate 7 and to provide the necessary downstream pressure. .
