Description
,7aoooo9-a _endast verktygshâllaren med verktyget behöver bytas ut vid sönder- 4körning. " f Ändamålet uppnås med den anordning, som framgår av efterföljan- de patentkravs kännetecknande del. I Uppfinningen kommer nu att beskrivas med ett utföringsexempel under hänvisning till medföljande ritning, i vilken fig 1 visar en sprängvy av anordningen, och fig 2 visar ett delsnitt av anordningen i hopmonterat läge. , 7aoooo9-a _only the tool holder with the tool needs to be replaced during disassembly. The object is achieved with the device, which appears from the characterizing part of the following claims. The invention will now be described with an exemplary embodiment with reference to the accompanying drawing, in which Fig. 1 shows an exploded view of the device, and Fig. 2 shows a partial section of the device in assembled position.
Fig 1 visar ett aggregat 1, 2 för skärande bearbetning. En ändfräsdorn 2 är med sitt bakre, koniska parti avsett att sättas i en maskin. Denna dorn följer med maskinen vid leveransen och enligt uppfinningen är dornen således ett organ, på vilket en verktygs- hållare 1 med ett systemverktyg av något slag kan infästas. Pâ rit- ningen är verktygshållaren ett arborrhuvud.Fig. 1 shows an assembly 1, 2 for cutting machining. An end mill mandrel 2 with its rear, conical portion is intended to be inserted into a machine. This mandrel accompanies the machine on delivery and according to the invention the mandrel is thus a member to which a tool holder 1 with a system tool of some kind can be attached. In the drawing, the tool holder is a drill bit.
För infästning av arborrhuvudet på ändfräsdornen förfar man enligt följande: En hållarskruv 9 med ett huvud 8 skruvas in i en gängad borrning 7 i en på dornens 2 cylindriska parti 4 koncentriskt anordnad tapp 6, varvid hållarskruvens huvud har huvudsakligen samma största diameter som tappen. Verktygshållaren l, som har en axiell borrning 10 är genom skjutpassning anbringbar på tappen 6 till anligg- ning mot det cylindriska partiets 4 ändyta 16 på dornen 2, varvid ett spår ll på verktygshållaren ingriper med en kil 5 på dornen, vilket fasthåller verktygshållaren i vridriktningen på dornen. I utföringsexemplet finns två diametralt motsatta kilar 5 och tvâ mot- svarande spårfill. När verktygshållaren är förd till anliggning mot ändytan 16 befinner sig i gängade kanaler 17 i hållaren anordnade låsskruvar 12 radiellt utanför och axiellt mittför en konisk yta 2 13 av hållarskruvens 9 huvud 8. I detta exempel finns tre stycken lâsskruvar,p1acerade med l20° mellanrum runt verktygshâllaren. Vid inskruvning av låsskruvarna 12 ingriper ett koniskt ändparti 14 av dessa med den koniska ytan 13 pâ huvudet 8. Detta arrangemang fasthâller verktygshâllaren 1 i akiell riktning på dornen 2. 2 Således har man med anordningen enligt uppfinningen åstadkommit en verktygshållare, som är fixerbar på ändfästdornen men som kan utbytas vid sönderkörning av verktyget.To fasten the drill bit head to the end mill mandrel, proceed as follows: A retaining screw 9 with a head 8 is screwed into a threaded bore 7 in a pin 6 concentrically arranged on the cylindrical portion 4 of the mandrel 2, the holder screw head having substantially the same largest diameter as the pin. The tool holder 1, which has an axial bore 10, is slidably fitted on the pin 6 to abut against the end surface 16 of the cylindrical portion 4 on the mandrel 2, a groove 11 on the tool holder engaging a wedge 5 on the mandrel, which holds the tool holder in the direction of rotation on the mandrel. In the exemplary embodiment, there are two diametrically opposite wedges 5 and two corresponding grooves fi ll. When the tool holder is brought into abutment against the end surface 16, locking screws 12 arranged radially outside and axially opposite a conical surface 21 of the holder screw 9 are arranged in threaded channels 17 in the holder. In this example there are three locking screws, spaced 120 ° apart around the tool holder. When screwing in the locking screws 12, a conical end portion 14 thereof engages with the conical surface 13 on the head 8. This arrangement holds the tool holder 1 in the axial direction on the mandrel 2. Thus, with the device according to the invention a tool holder is provided which is fixable on the end mounting mandrel but which can be replaced when the tool breaks.
