Abstract

Mandrina cu vîrf de centrare si bacuri flotante actionata mecanic, conform inventiei, se utilizeaza pentru fixarea si antrenarea semifabricatelor între vîrfuri la prelucrarea prin aschiere. Se poate monta pe toate strungurile ce sunt dotate cu papusa mobila sau în cazul utilizarii ca universal autocentrant, pe orice varianta constructiva de strung. Este formata dintr-un corp în care este actionat un ansamblu culisant compus dintr-un disc de ghidare si o bucsa de actionare, un disc flotant radial, prevazut cu trei furci frontale cu cîte doua brate înclinate, bacuri de conducere antrenate cu bolturi aplatizate. Pentru centrarea semifabricatelor si mentinerea lor între vîrfuri, foloseste o flansa în interiorul careia ghideaza vîrful de centrare. în scopul transformarii în universal cu bacuri autocentrante, fara trecere, foloseste niste suruburi de ghidare, piulite crenelate, pentru blocarea discului de ghidare, bucsa de actionare si disc flotant, iar pentru transformarea în universal autocentrant cu trecere, foloseste o bucsa de protectie. Ungerea întregului sistem este realizata cu ungatoare cu bila.The mandrel with centering tip and mechanically operated floating blades according to the invention is used for fastening and driving the semifinished products between the peaks at the cutting process. It can be mounted on all the lathes that are equipped with the mobile doll or when used as a universal self-centering, on any constructive lathe variant. It consists of a body in which a sliding assembly consists of a guide disk and a drive blade, a radial floating disk, provided with three front forks with two inclined arms, driving jaws with flattened bolts. To center the semi-fabrics and keep them between peaks, use a flange inside which guides the tip of the centering. For the purpose of transforming it into a self-centerless, non-passage, it uses guide nuts, crimped nuts to lock the guide disc, drive bush and floating disc, and uses a protective sleeve to transform it into a universal self-centering passage. The whole system is lubricated with ball mills.
