Description
Anordning til å fastholde en bormeisel som tjener til fremstilling av plugghull i betong, murverk o. 1., og sikre den mot dreining i en verktøyholder. Device for holding a drill bit used for making dowel holes in concrete, masonry etc., and securing it against turning in a tool holder.
Oppfinnelsen angår en anordning til å The invention relates to a device to
fastholde en bormeisel som tjener til fremstilling av plugghull i betong, murverk o. 1., maintain a drill bit that is used for making dowel holes in concrete, masonry etc. 1.,
i en verktøyholder og sikre den mot dreining i denne. Anordningen er særlig be-stemt for slike bormeisler som er utstanset in a tool holder and secure it against turning in this. The device is particularly intended for drill bits of this type that have been punched out
i rett vinkel fra en plate og deretter delvis at right angles from a plate and then partially
innrullet slik at der gjenstår et ribbelignende fremspring ved den bakre ende av rolled in so that a rib-like projection remains at the rear end of
meiselen. the chisel.
Ved kjente verktøy av denne art har In known tools of this kind have
bormeiselen vært holdt og sikret mot dreining i en verktøyholder som borskaftet the drill bit has been held and secured against turning in a tool holder like the drill shank
stikkes inn i, ved hj elp av særskilte organer inserted into, with the help of special organs
som er anordnet på verktøyholderen som f. which is arranged on the tool holder such as
eks. kiler eller koniske ringer, eller ved en e.g. wedges or conical rings, or by a
oppdeling av borskaftet i bajonettformig division of the drill shaft into bayonet-shaped
forbundne deler eller ved hjelp av låse-stifter innsatt på tvers gjennom borhol-deren. connected parts or by means of locking pins inserted transversely through the drill holder.
I motsetning til disse verktøy, som er In contrast to these tools, which are
kostbare og fremstilt av metall, blir der expensive and made of metal, stays there
ifølge oppfinnelsen foreslått en verktøyhol-der som har form av et vinkelformet plasthåndtak, hvis frie ben har boringer som according to the invention, a tool holder is proposed which has the shape of an angular plastic handle, whose free legs have bores that
tjener til å oppta bormeisler med forskjellige diametre og som er utformet med en serves to accommodate drill bits of different diameters and which are designed with a
sliss som et ribbelignende fremspring ved slit as a rib-like projection at
den bakre ende av bormeiselen er innrettet the rear end of the drill is aligned
til å gripe inn i for å hindre meiselen i å to engage in to prevent the chisel from
dreie seg i holderen. turn in the holder.
Por å sikre bormeiselen mot aksialfor-skyvnihg i boringen er vidden av den med To secure the drill bit against axial displacement in the borehole, the width of the bit is included
boringen forbundne sliss mindre enn godstykkelsen av det ribbelignende fremspring, the bore connected slots smaller than the thickness of the rib-like projection,
så der oppnås en fjærende fastklemming. so a resilient clamping is achieved.
En slik dreie- og holdesikring av bormeiselen har den fordel at det på en enkel måte sørges for at der kan anvendes bormeisler med forskjellige diametre, samtidig som et ben av verktøyet stadig tjener som håndtak. Festeanordningen har dessuten den fordel at den kan fremstilles billig ved at der anvendes plast. Such a turning and holding protection of the drill bit has the advantage that it is ensured in a simple way that drill bits with different diameters can be used, while one leg of the tool still serves as a handle. The fastening device also has the advantage that it can be produced cheaply by using plastic.
På tegningen er der vist et utførelses-eksempel på anordningen ifølge oppfinnelsen. The drawing shows an embodiment of the device according to the invention.
Fig. 1 er et lengdesnitt av anordningen, Fig. 1 is a longitudinal section of the device,
tatt langs linjen I—I på fig. 2. taken along the line I—I in fig. 2.
Fig. 2 er et perspektivriss av anordningen. Fig. 2 is a perspective view of the device.
Verktøyholderen består av et vinkelformet håndtak som danner to frie ben 1 og 2. Som materiale for dette håndtak anvendes en plast som tåler hammerslag uten å gå i stykker, f. eks. nylon. The tool holder consists of an angular handle that forms two free legs 1 and 2. The material used for this handle is a plastic that can withstand hammer blows without breaking, e.g. nylon.
Ved de frie ender av benene har håndtaket boringer 3 og 4 med forskjellige diametre, slik at der i disse boringer kan set-tes inn bormeisler med forskjellige diametre. Ved sin bakre ende er bormeiselen 5 forsynt med et ribbelignende fremspring At the free ends of the legs, the handle has bores 3 and 4 of different diameters, so that drill bits of different diameters can be inserted into these bores. At its rear end, the drill bit 5 is provided with a rib-like projection
6 til å sikre den mot dreining. 6 to secure it against rotation.
Slike bormeisler dannes som kjent ved at de utstanses i rett vinkel fra en plate, samtidig som skjæreeggen dannes, og idet der levnes et ribbelignende fremspring. As is known, such drill bits are formed by punching them out at a right angle from a plate, at the same time as the cutting edge is formed, leaving a rib-like projection.
Som det fremgår av tegningen, er bo-ringene 3 og 4 utformet med hver sin sliss 3a resp. 4a som er tilpasset det ribbelignende fremspring som tjener til dreiesik-ring. For samtidig å sikre bormeislene mot å trekkes ut fra håndtaket 1, 2 eller for-skyves aksialt i boringen 4, resp. 3, er slis-sen 4a, resp. 3a, utført med en noe mindre vidde enn godstykkelsen av det ribbelignende fremspring 6. Dermed oppnås en fjærende fastklemming av bormeiselen 5. As can be seen from the drawing, the bore rings 3 and 4 are each designed with a slot 3a or 4a which is adapted to the rib-like projection which serves as a rotation lock. In order at the same time to secure the drill bits against being pulled out from the handle 1, 2 or pushed axially in the bore 4, resp. 3, is the slot 4a, resp. 3a, made with a slightly smaller width than the thickness of the rib-like projection 6. Thus, a resilient clamping of the drill bit 5 is achieved.
Etterat bormeiselen 5 med sitt fremspring 6 er innsatt i boringen 4 i benet 2, kan det annet, frie ben 1, som ikke opptar noen bormeisel, tjene som håndtak for meislingen. For å gi boret 5 godt hold i verktøyholderen må boret bankes inn i håndtaket 1, 2. Til dette formål blir håndtaket lagt på et fast underlag, hvorpå boret slås inn i boringen 3 eller 4 i håndtaket 1, 2 med en hammer. Selvfølgelig kan den be-skrevne dreie- og holdesikring også anvendes for bor av massivt gods. After the drill bit 5 with its projection 6 has been inserted into the bore 4 in the leg 2, the other, free leg 1, which does not accommodate a drill bit, can serve as a handle for the chisel. To give the drill 5 a good hold in the tool holder, the drill must be tapped into the handle 1, 2. For this purpose, the handle is placed on a firm surface, after which the drill is driven into the bore 3 or 4 in the handle 1, 2 with a hammer. Of course, the described turning and holding device can also be used for drilling solid goods.
Alt etter lengden av de frie ben 1 og 2 vil det la seg gjøre å anordne ytterligere boringer for bormeisler med andre diametre. Depending on the length of the free legs 1 and 2, it will be possible to arrange additional holes for drill bits with other diameters.
