Abstract

Inventia se refera la un portcutit cu reglaj fin si retragere rapida a sculei, care realizeaza fixarea si pozitionarea cutitului de strunjit, în cazul strunjirii de finisare a suprafetelor interioare sau exterioare ale unor piese. Portcutitul, conform inventiei, este prevazut cu un suport superior care se poate deplasa pe suportul inferior, fiind actionat hidraulic, pe un ghidaj în forma de V, în care este apasat permanent de doua pachete de arcuri disc, care elimina jocurile din ghidaj, permitînd realizarea unor deplasari precise. Reglarea fortei de apasare a arcurilor se realizeaza cu doua bucse filetate, astfel, pentru reglajul micrometric nu se strînge sau slabeste fixarea suportului superior de cel inferior.The invention relates to a finely tuned tool holder and quick tool retraction which performs the fixing and positioning of the turning knife in the case of finishing of the inner or outer surfaces of parts. The tool holder according to the invention is provided with a top support which can move on the lower support and is hydraulically operated on a V-shaped guide in which it is permanently pressed by two disc spring bundles, which eliminates gaming from the guide, making precise movements. The adjustment of the spring force is achieved with two threaded bushings, so the micrometric adjustment does not collapse or weakens the fixing of the upper bracket to the lower one.
