Abstract

Zariadenie je zvlášť vhodné pre elektrochemický popis valivých ložísk. Podstatou je popisovacia hlava, umožňujúca rýchlu výměnu popisovacej šablony pri zmene typorozmeru, v ktorej je popisovacia šablona s elektrolytem a příslušným podtlakem. V popisovacej hlavě je vložená zhora popisovacia šablona, ktorá je utěsněná po obvode přítlačným kotúčom pritláčaným středovou maticou vo veku popisovacej hlavy. Veko vzduchotěsně uzaviera popisovaciu hlavu pomocou dvoch bočných matic. V popisovacej hlavě je vytvořený podtlak, zamedzujúci samovolné vytekanie elektrolytu cez popisovacie znaky, pomocou podtlakovej hadice. Elektrolyt je privádzaný cez napúšťaciu hadicu a odvádzaný cez vypúšťaciu hadicu. Hadice sú spojené s držiakmi, v ktorých sú vložené rúrky, klbovo spojené s popisovacou hlavou. Popisovacia hlava je výkyvná v dvoch rovinách, pomocou příslušných držiakov, čo umožňuje přesné dosadanie popisovacej hlavy na popisované ložisko.The device is particularly suitable for electrochemical marking of rolling bearings. The essence is a marking head, enabling quick change of the marking template when changing the type size, in which the marking template with electrolyte and the corresponding vacuum is located. A marking template is inserted from above in the marking head, which is sealed around the circumference by a pressure disc pressed by a central nut in the marking head lid. The lid closes the marking head airtightly by means of two side nuts. A vacuum is created in the marking head, preventing the electrolyte from spontaneously flowing out through the marking marks, by means of a vacuum hose. The electrolyte is supplied through the inlet hose and discharged through the outlet hose. The hoses are connected to holders in which pipes are inserted, articulated with the marking head. The marking head can be pivoted in two planes using appropriate holders, which allows for precise positioning of the marking head on the bearing being marked.

Vynález sa týká zariadenia ina elektro-chemický popis kruhových súčiastok i va-livých ložísk.BACKGROUND OF THE INVENTION The present invention relates to an apparatus and to an electro-chemical description of circular components and rolling bearings.

Doterajšia technológia popisu kruhovýchsúčiastok i valivých ložísk sa prevádza ná-sledovně. Základný popis sa prevádza nahydraulických lisoch pomocou ocelovýchrazníc a dodatkový popis sa prevádza potechnické] kontrole ručně dopisováním po-mocou kyseliny.The prior art technology for the description of circular components and rolling bearings is as follows. The basic description is carried out on hydraulic presses by means of steel dies and the additional description is carried out by a technical inspection by manually corresponding to the acidity.

Pri popisovaní na hydraulických lisochdochádza k deformáciám, čo nemá dobrývplyv na kvalitu hotových ložísk. Tiež dal-ší rozvoj v oblasti zahraničiného obchodu slvyžaduje změnit sposob značenia valivýchložísk z mechanické!» na elektrochemickéoznačovanie. Pri popisovaní valivých lo-žísk majú mnohé typorozmery až 50 apli-kácií prevedenia. Výměna popisovacieho za-riadenia musí byt z toho důvodu velmi rých-la.When describing on hydraulic presses, deformations occur, which does not affect the quality of finished bearings. Further development in the field of foreign trade also requires changing the way of marking the roller bearings from mechanical to electrochemical marking. Upon application of rolling bearings, many types of dimensions have up to 50 applications. Therefore, the exchange of the inscription device must be very fast.
