Description

Tuleja obrotowa 3, nakrecona jest bezposrednio na wrzeciono 2 automatu. W tuleji obrotowej 3, umieszczona jest tuleja prowadzaca 6, w której wykonany jest otwór pod katem odpowiadajacym katowi pochylenia otworu stozkowego. W tuleji prowadzacej 6, przesuwa sie wytaczadlo 4 z zamo¬ cowanym nozem. Wytaczadlo zabezpieczone jest przed przesunieciem wzdluz osi wrzeciennika sworzniem ustalajacym 5. Stala tuleja 9, oparta jest o korpus 1 systemu nozowego automatu i unie¬ ruchomiona mocujacym trzpieniem 8, osadzonym w otworze sworznia loza wahliwego. Nastawna tuleja 10, sluzy do dokladnej regulacji srednicy wytaczanego otworu. Nakretka 11 ustala pierscien prowadzacy 7.Urzadzenie wedlug wynalazku, moze byc rów¬ niez stosowane do wytaczania otworów na obra¬ biarkach nie posiadajacych posuwu poprzecznych do osi toczenia. PLRotary sleeve 3 is screwed directly onto the spindle 2 of the machine. In the rotary sleeve 3, a guide sleeve 6 is placed, in which a hole is made at an angle corresponding to the inclination angle of the taper hole. In the guide sleeve 6, the boring bar 4 is moved with the inserted knife. The boring bar is secured against shifting along the axis of the headstock by means of a fixing pin 5. A fixed bushing 9 rests on the body 1 of the automatic knife system and is immobilized by a fixing pin 8, embedded in the hole of the pin of the pendulum bed. The adjustable sleeve 10 is used for fine adjustment of the diameter of the bored hole. The nut 11 fixes the guide ring 7. The device according to the invention can also be used for boring holes in machine tools that do not have a feed transverse to the turning axis. PL
