Description

Vynález sa týká zhotovenia pracovného nástroj a pre elektrochemické odhrotovanie otvorov, najma v ťažko přístupných miestach.The invention relates to the construction of a working tool and for electrochemical deburring of holes, in particular in hard-to-reach places.

Elektrochemické odhrotovanie otvorov v miestach, ktoré sú ťažko přístupné sa uskutečňuje v uzatvorených priestoroch, komorách, alebo v prípravkoch elektrochemických zariadení zvlášť prispósobených k tomuto účelu. Preto velkost odhrotovávanej súčiastky je limitovaná veikosťou komory, alebo přípravku. Súčiastky, ktorých odhrotovávané otvory sú skloněné pod róznymi uhlami, alebo súčiastky rozměrově velké nie je možné na týchto známých elektrochemických zariadeniach odhrotovávať. U rozměrově zvlášť velkých súčiastok sa na odhrotovávanie otvorov používá ručná odhrotovávacia jednotka, ktorá sa počas obrábania drží v ruke. Je známe aj upínanie. pracovných odhrotovávacích nástrojov na obrobku mechanické, pneumatické alebo hydraulické. Nevýhodou týchto pracovných nástrojov je, že u ručných obsluha móže pracovat len s jedným pracovným nástrojom. Mechanické, pneumatické, alebo hydraulické upínanie pracovných nástrojov na obrobku je riešené poměrně zložitými a výrobně nákladnými prvkami.Electrochemical deburring of openings in places that are difficult to access takes place in confined spaces, chambers, or in preparations of electrochemical equipment specially adapted for this purpose. Therefore, the size of the deburring component is limited by the size of the chamber or fixture. Components whose deburring holes are inclined at different angles or components large in size cannot be deburred on these known electrochemical devices. For particularly large components, a manual deburring unit is used to deburr the holes, which is held in the hand during machining. Clamping is also known. work deburring tools on a workpiece mechanical, pneumatic or hydraulic. The disadvantage of these work tools is that only one work tool can be used by manual operators. Mechanical, pneumatic or hydraulic clamping of work tools on the workpiece is solved by relatively complicated and costly elements.

Vyššie uvedené nevýhody odstraňuje a technický problém rieši pracovný nástroj pre elektrochemické odhrotovanie otvorov, najma v ťažko přístupných miestach podl’a vynálezu, ktorého podstatou je, že na povrchu telesa nad činnou plochou pracovného nástroja na elektroizolačnej vložke je prestavitelne uložený elektromagnet. Podstatou vynálezu je aj to, že elektromagnet je připojený na zdroj pracovného prúdu. Do podstaty vynálezu patří i to, že elektromagnet je připojený na samostatný zdroj prúdu.The above-mentioned disadvantages are overcome and the technical problem is solved by a working tool for electrochemical deburring of holes, especially in hard-to-reach places according to the invention, whose essence is that the electromagnet is adjustable on the body surface above the working surface of the working tool. It is also an object of the invention that the electromagnet is connected to a working current source. It is a further object of the invention that the electromagnet is connected to a separate power source.

Pracovným nástrojom podlá vynálezu sa docieli toho, že pracovný nástroj je možné upnúť priamo na ktorékolvek miesto obrobku, čím nie je potřebné vyrábat strojnú část elektrochemického obrábacieho zariadenia, to je trému s pohybovými a upínacími časťami. Odstráni sa aj pracné polohovanie obrobku voči pracovnému nástrojů upnutému v hlavě stroja. Použitím samostatného zdroja prúdu pre upínanie pracovného nástroj a je možné súčasne pracovat s viacerými pracovnými nástrojmi, čo podstatné znižuje prácnosť hlavně u obrobkov s viacerými obrábanými miestami.The working tool according to the invention achieves that the working tool can be clamped directly to any part of the workpiece, so that it is not necessary to manufacture the machine part of the electrochemical machine tool, i.e. the stage with the movement and clamping parts. The laborious positioning of the workpiece in relation to the work tool clamped in the machine head is also eliminated. By using a separate power source for clamping the work tool and it is possible to work with several work tools at the same time, which significantly reduces workload, especially for workpieces with multiple machining points.

Pracovný nástroj pozostáva z telesa 1 (obr. 1), ktorý má na dolnom konci vytvorenú činnú plochu 2. V pozdížnej osi telesa 1 je vytvořený prívodný kanál 10 elektrolytu, ktorý vyúsťuje v blízkosti činnej plochy 2. Na telese 1 nad činnou plochou 2 je vsuvne uložená elektroizolačná vložka 3, pričom medzi činnou plochou 2 a elektroizolačnou vložkou 3 je uložená stavacia podložka 11. Na elektroizolačnej vložke 3 je skrutkami 12 pevne uchytené jádro 7 elektromagnetu 6. V medzikruží jadra 7 je uložená cievka 8, na ktorej vonkajšom čele je uložená v medzikruží jadra 7 elektroizolačná podložka 9. Nad elektroizolačnou vložkou 3 sú na telese 1 naskrutkované dve matice 13, medzi ktorými je pevne uchytená svorka 14 elektrického prúdu. Maticami 13 je zároveň pevne uchytená elektroizolačná vložka 3 na stavacej podložke 11 telesa 1. Na horný koniec telesa 1 je připojená prívodná hadica 15 elektrolytu. Na svorku 14 telesa 1 pracovného nástroja je připojený záporný pól a na obrobok kladný pól zdroja 4 pracovného prúdu. Elektromagnet 6 pracovného nástroja (obr. 2) móže byť připojený na samostatný zdroj 5 prúdu, alebo móže byť připojený na zdroj 4 pracovného prúdu (obr. 3).The working tool consists of a body 1 (FIG. 1) having a working surface 2 formed at the lower end thereof. In the longitudinal axis of the body 1 an electrolyte supply channel 10 is formed, which opens near the working surface 2. a plug washer 11 is mounted between the active surface 2 and the plug 3, and a core 7 of the electromagnet 6 is fixed by screws 12 in the plug 3. In the annulus of the core 7, the electrical insulating washer 9. Above the electrical insulating insert 3, two nuts 13 are screwed on the body 1, between which the electrical current terminal 14 is fixed. At the same time, the insulating insert 3 is fixedly fixed by the nuts 13 on the adjusting washer 11 of the body 1. The electrolyte supply hose 15 is connected to the upper end of the body 1. A negative pole is connected to the terminal 14 of the tool body 1 and to the workpiece the positive pole of the power source 4 is connected.
