Pa ritningen visas endast den som exempel valda verktygshallarea, som Or tankt anvand pit en svarv. Den Minanda ballare uppbarande supporten visas icke, da den Or i och fOr sig hand.. The drawing only shows the tool hall area selected as an example, which Or tankt used a lathe. The Minanda ballare bearing support is not shown, as it is in and of itself.

Det I fig. 1, 2 och 8 visade blocket 1, med ratvinkligt tvarsnitt, av verktygshallaren har, for fastsiittning pa svervsupporten, ett hal 2, genom vilket supportens klamskruv Ran iradas. Vidare bar hallareblocket 1 en osymnietriskt anordnad, konisk, langsgaende borrning 3 for upptagande av den som en morsekona utformade tappen eller axein 5 for .ett revolverhuvud 4 (fig. 5). Axeltappen 5 liar en insvarvning 6, i vilken forreglingsanordningens forreglingsgaffel 8 ingriper. Namnda gaffel sitter vridbar pit den vinkelratt mot borrningert 3 i blocket 1 insatta forreglingsbultens 10 inre aide. Narmare bestamt Or del gaffeln 3 hallande stiftet P exeentriskt inpressat i hultens 10 ande, sasom framgar av fig. 0. Millen 10 har pa omkretsen ett i huvudsak Z-formigt styrspar 11 med delarna in, n och o (_fig. 7 och 8), i vilket ett i blocket 1 sittande stye-stilt 12 ingriper (fig. ii. Vidare har bulten 10 en insvarvning 13, van i ingriper en bladfjader 14, sum medelst skruven 18 Or fast .pa sidan av blocket 1. For manayrering av farreglingsanordningen instickes eti handtag I ett tviirgitende hal. 15 i bulten 10. The block 1, with a right-angled cross-section, shown in Figs. 1, 2 and 8, of the tool holder has, for attachment to the swivel support, a hole 2, through which the support clamping screw Ran is inserted. Furthermore, the holder block 1 carried an asymmetrically arranged, conical, longitudinal bore 3 for receiving the pin-shaped pin or axle 5 for a turret 4 (Fig. 5). The shaft pin 5 has a turning 6, in which the interlocking fork 8 of the interlocking device engages. Said fork sits rotatably pit it perpendicular to bore 3 in the block 1 inserted the inner aide of the locking bolt 10. More specifically, the part P holding the pin P is eccentrically pressed into the spirit of the hollow 10, as shown in Fig. 0. The mill 10 has on the circumference a substantially Z-shaped guide pair 11 with the parts in, n and o (Figs. 7 and 8). , in which a stye-still 12 sitting in the block 1 engages (fig. ii. Furthermore, the bolt 10 has a turning 13, used in engaging a leaf spring 14, which is fixed by means of the screw 18 Or fixed on the side of the block 1. For maneuvering the fairing control device insert a handle into a double-ended hall 15 in the bolt 10.

Det i fig. 5 visa-de revolverhuvudet 4 Or for-sett med fyra vid andytan appna slitsar a, b, c och d, i vilka verktyg pit vanligt satt kunna insattas och fastklammas medelst skruvar. Pit hidlarens framre andyta Oro anbragta fyra, pit inbordes lika avstand sittande stilt 16, som ingripa i fyra motsvarande hiti i revolverhuvudet for att forhindra en icke anskad vridning av detsamma och som vid vridning av revolverhuvudet for omstallande av verktygen fixera detsamma i ett alltid bestamt lage. I hallaren kunna givetvis revolverhuvud.en av olika slag och olika verktyg insattas. SO kin t. ex. far ursvarvningsarbeten i stallet for re- — — volverhuvudet insattas (let i fig. 10 visade syarystalet, vars skaft for delta andamal likaledes är utformat som en i borrningen 3 passande morsekona 5 med insvarvning (3. Verktygshallaren kan efter behag inspannas tangs med, tvars emot eller snett i forhallande till svarvbadden. Inspiinningen i langdriktningen lampar sig val for invandig bearbetning av arbetsstycken, medan inspanning i tvarriktningen är gynnsammare for utviindig bearbetning av langre arbetsstycken. I senare fallet vandes verktygshallaren och uppspiinnes sasom fraingar av fig. 3. The turret 4 Or shown in Fig. 5 is provided with four slots a, b, c and d open at the front surface, into which tools the pit can normally be inserted and clamped by means of screws. The front end face of the pit heater is arranged four, the pit is embedded equally spaced still 16, which engage in four corresponding hiti in the turret to prevent an undamaged rotation of the same and which when rotating the turret for rearranging the tools fix the same in an always fixed position. . In the hall, of course, revolver heads of different kinds and different tools can be inserted. SO can e.g. The turning tool in the stable for the re- - - volver head is inserted (the figure shown in Fig. 10 shows, the shaft for delta andamal is also designed as a morse cone 5 fitting in the bore 3 with turning in). The indentation in the longitudinal direction is suitable for internal machining of workpieces, while indentation in the transverse direction is more favorable for external machining of longer workpieces.

Den beskrivna verktygshallarens vertningssatt Or foljande: Verktygshallaren inspannes i supporten pa en svarv, varvid supportens kliimskruv Fires genom halet 2 i blocket 1. Forreglingsanordningen Or medelst armen bragt till frilage, varvid fjadern 14 liar splints genom forskjutningen utat av bulten 10, och revolverhuvudets 4 morsekona 5 inskjutes framifran i borrningen 3. Styrstiftet 12 ingriper i detta liige i bultens 10 spArdel m och sparrar bulten, sa att denna icke kan skjutas inat av fjadern 14. Nu \Tides bulten 10 medurs medelst armen 7 (fig. 1), varigenom stiftet 12 fores ur spardelen in till delen n, varvid bladfjadern 14 driver bulten 10 in i blockets 1 borrning, tills stiftet 12 kommit in i spardelen a. Harigenom skjutes gaffeln 8 in ursvarvningen 6 pa axeln S och drager, am bulten 10 yrides ytterligare medurs, densamma helt in i borrningen 3 och forreglar den, varvid stiften 16 fasihalla den mot vridning ur dess ratta lage. The tool holder is described in the support on a lathe, the support clamping screw being passed through the hole 2 in block 1. The interlocking device is brought into neutral by means of the arm, the spring 14 being splintered by the offset of the bolt 10, and the turret head. 5, the guide pin 12 engages in this liige in the ratchet m of the bolt 10 and locks the bolt so that it cannot be pushed inwards by the spring 14. Now the bolt 10 is moved clockwise by means of the arm 7 (Fig. 1), whereby the pin 12 is inserted from the spare part into the part n, the leaf spring 14 pushing the bolt 10 into the bore of the block 1, until the pin 12 enters the saving part a. the same completely into the bore 3 and locks it, the pins 16 holding it against rotation out of its steering wheel bearing.

Om nu ett annat verktyg i revolverhuvudet 4 shall bringas till arbetslage I stallet for det installda verktyget, fores armen 7 moturs (fig. 1), sa att gaffeln 8 driver ut axeln 5 ett stycke ur borrningen 3 och harigenom lossar revolverhuvudet. Armen 7 i:yiinges harvid sa 'nyeket, att huvudets 4 hal komma ur samverkan med hallarens stiltAxeln 5 sitter nu lost i borrningen 3 oeh liar tillrOekligt spelrum, for att revalverhuvndet 4 stall kunna vridas till Onstat lage. Daref ter svanges armen 7 liter tillbaka, varigenom axeln 5 ater fiirreglas I borrningen 3 i sitt nya lage. If now another tool in the turret 4 is to be brought into working position Instead of the installed tool, the arm 7 is moved counterclockwise (Fig. 1), so that the fork 8 drives the shaft 5 some distance out of the bore 3 and thereby loosens the turret. The arm 7 i: yiinges harvid sa 'nyeket, that the head 4 hal come out of cooperation with the hallar's stiltAxeln 5 is now lost in the bore 3 oeh liar sufficient clearance, so that the revalverhuvndet 4 stall can be turned to Onstat lage. Then the arm is swung 7 liters back, whereby the shaft 5 is again locked in the bore 3 in its new bearing.

Om revolverhuvudet 4 skall ersattas med ett annat, sO svanges armen 7 Ater moturs (fig. 1), tills man kan draga ut bulten 10 sa langt, att gaffeln 8 belt kommer utanfor insvarvningen 6. Yid ytterligare -Vridning .av bulten trader stiftet 12 in i spardelen in och arreterar bulten 10. Nu kan revolverhuvudet 4 dragas ut och ett annat dylikt sattas in och ater forreglas, varvid manovreringen Or densamma som ovan beskrivits. I stallet for ett revolverhuvud kan Oven ett enkelt verktyg, t. ex. del i fig. 10 visade svarystalet 17, insfittas p0 samma satt. If the turret 4 is to be replaced with another, the arm 7 is pivoted counterclockwise (Fig. 1), until the bolt 10 can be pulled out so far that the fork 8 belt comes out of the turn-in 6. Yid further -Turnation of the bolt trades the pin 12 into the spare part and locks the bolt 10. Now the turret 4 can be pulled out and another such can be inserted and locked again, the maneuvering Or being the same as described above. Instead of a turret, Oven can use a simple tool, e.g. part in Fig. 10 the response number 17, is fitted in the same way.

I motsats till lianda stalhallare med icke atbytbart revolverhuvud ,och verktygshallare liar uppfinningsforemillet den fordelen, att ett utbyte av verktyget eller revolverhuvudet Or mojligt, utan att hallaren vane gang maste spannas loss och installningen 1 svarven foretagas I nytt. In contrast to steel holders with non-replaceable turrets, and tool holders, the inventive form has the advantage that an exchange of the tool or turret is possible, without the holder having to be loosened as usual and the installation in the lathe being carried out again.
