Description
Predmetom vynálezu je vyvrtávacia hlava radiálně nastavitelná s nožmi opatřenými vyměnitelnými režnými doštičkami zo spekaného karbidu, najma pre vyvrtávanie dier. Pre vyvrtávanie dier od priemeru 120 mm a viac sa používajú rózne typy pevných i nastavitelných vyvrtávacích hláv.The object of the invention is a boring head radially adjustable with knives provided with replaceable sintered carbide cutting inserts, in particular for boring holes. Various types of fixed and adjustable boring heads are used for boring holes with a diameter of 120 mm and more.
Nevýhodou u pevných vyvrtávacích hláv je nutnost’ výroby hlavy pre každý vyvrtávací rozměr.The disadvantage of fixed boring heads is the necessity of producing heads for each boring dimension.
V poslednej době sú pevné hlavy vytláčané radiálně nastavitelnými hlavami. Výhodou vyvrtávacej hlavy podlá vynálezu oproti pevným hlavám je v možnosti radiálneho nastavenia nožov pre určitý vyvrtávací rozsah.Recently, fixed heads have been extruded by radially adjustable heads. The advantage of the boring head according to the invention over fixed heads is the possibility of radial adjustment of the blades for a certain boring range.
Konštrukcia dvojnožovej vyvrtávacej hlavy podlá obr. 1, 2 a 3 sa skládá z frézovacieho tfňa 10, telesa 20 hlavy, telesa noža 40, upínacieho klina 90, upínacích skrutiek 30 a 100.The construction of the two-bore boring head according to FIG. 1, 2 and 3 consists of a milling cutter 10, a head body 20, a knife body 40, a clamping wedge 90, clamping screws 30 and 100.
U vyvrtávacej hlavy podlá obr. 2 sa na frézovací třň 10 upevňuje teleso 20 hlavy, pomocou upínacích skrutiek 30. V telese 20 hlavy podra obr. 3, sú vytvořené navzájom opačné rombické drážky 21, v ktorých sú uložené nožové držiaky 40, ktoré sú na spodněj časti 41 skosené. V nožových držiakoch 40. podra obr. 2 sú vytvořené drážky 42, pre uloženie režných doštičiek 50 zo spekaného karbidu, ktoré sú uchytené pomocou upínacej skrutky 60 a úpinky 70. Na boku nožového držiaka 40 je priečna drážka 43, do ktorej zapadá hlava mikrometrickej skrutky 80 s ovládacím zahíbením 81, pre kluč na radiálně nastavenie. Hlava mikrometrickej skrutky 80 prechádza otvorom 22 v telese hlavy. Driek mikrometrickej skrutky 80 je zaskrutkovaný do telesa 20 hlavy. Po nastavení na požadovaný priemer obrábania sa nožový držiak 40 podlá obr. 1 upne pomocu upínacieho klina 90, ktorý je na vrchnej časti skosený 91 a uchytený pomocou upínacích skrutiek 100. V drážkách 11 frézovacieho třňa 10 podlá obr. 3 a drážkách 23 vyvrtávacej hlavy sú uložené unášacie kamene 110, ktoré sú upevněné pomocou upínacej skrutky 120 na frézovací třň 10 za účelom prenášania krútiaceho momentu.In the boring head of FIG. 2, the head body 20 is fastened to the milling mandrel 10 by means of clamping screws 30. In the head body 20 of FIG. 3, opposite rhombic grooves 21 are formed, in which knife holders 40 are arranged, which are chamfered on the lower part 41. In the knife holders 40 of FIG. 2, grooves 42 are formed to receive the sintered carbide cutting inserts 50 which are fastened by a clamping screw 60 and a clamp 70. On the side of the knife holder 40 is a transverse groove 43 in which the head of the micrometer screw 80 with the control bore 81 fits for radial adjustment. The head of the micrometer screw 80 extends through an opening 22 in the head body. The shaft of the micrometer screw 80 is screwed into the head body 20. After adjusting to the desired machining diameter, the knife holder 40 of FIG. 1 is clamped by means of a clamping wedge 90, which is chamfered at the top 91 and clamped by clamping screws 100. In the grooves 11 of the milling mandrel 10 according to FIG. 3 and drilling head grooves 23 are provided with driving stones 110, which are fixed by means of a clamping screw 120 to the milling mandrel 10 in order to transmit the torque.
Konštrukcia radiálně nastavitefnej vyvrtávacej hlavy podlá vynálezu umožňuje vymieňať telesá nožov za účelom změny reznej geometrie nástroj a podlá druhu obrábaného materiálu. Jednou radiálně nastavitelnou vyvrtávacou hlavou sa nahradí v určitom priemerovom rozsahu niekolko pevných vyvrtávacích hláv, čím sa ušetria náklady na výrobu, materiál, prácnosť a sú menšie nároky na skladovací priestor.The design of the radially adjustable boring head according to the invention makes it possible to exchange the knife bodies in order to change the cutting geometry of the tool and according to the type of material to be machined. One radially adjustable boring head replaces several fixed boring heads over a certain diameter range, saving on production costs, material, labor and less storage space.
