Description

Oppfinnelsen angår en fresemaskin for fresing av spor og andre fordypninger, ifølge kravinnledningen. The invention relates to a milling machine for milling grooves and other depressions, according to the preamble.

For innarbeiding av spor og andre fordypninger i boringer er rømming vanlig benyttet. Rømmejern er imidlertid meget kostbare og krever meget vedlikehold og de kan i tillegg kun benyttes for en bestemt sporbredde. De har videre tekniske mangler ved sportaking da de ikke skjærer fri i sideretningen, nemlig nettopp der hvor det kreves en meget god overflatebeskaffenhet ved kilesporet. Denne ugunstige skjæring kan føre til brudd av rømmejernet ved høyfaste materialer. Reaming is commonly used for the incorporation of grooves and other depressions in boreholes. However, reamers are very expensive and require a lot of maintenance, and they can also only be used for a specific track width. They also have technical deficiencies when slotting as they do not cut freely in the lateral direction, precisely where a very good surface quality is required at the keyway. This unfavorable cutting can lead to breakage of the reamer in the case of high-strength materials.

Fra US 3 106 869 er en kopifresemaskin kjent hvormed spor kan freses i arbeidsstykkers indre. En vesentlig ulempe med denne maskin er at verktøyets drift foregår utenfra, slik at det kreves en stender for opplagring av drivanordningen, hvormed størrelsen av de arbeidsstykker som kan bearbeides, begrenses sterkt. From US 3 106 869 a copy milling machine is known with which grooves can be milled in the interior of workpieces. A significant disadvantage of this machine is that the tool's operation takes place from the outside, so that a stand is required for storage of the drive device, with which the size of the workpieces that can be processed is severely limited.

Det er videre kjent å fremstille spor i boringer ved innstikking. Innstikksmaskiner må imidlertid være bygget meget robuste mens nettopp dette ikke er mulig for verktøy-holderen på grunn av de begrensede plassforhold i boringen. Av denne grunn kan arbeidsstykker bare opptil en bestemt størrelse bearbeides med en verktøyholder, mens store arbeidsstykker i hvilke store og dype spor skal innarbeides, krever en tilsvarende større maskin. Ved lange spor som skal stikkes kan det imidlertid ikke unngås at verktøyet, det vil si stikkjernet, må rage langt ut, noe som fører til et avvik og dermed til en dårlig overflatebeskaffenhet. I tillegg stikker stikkjernet heller ikke fri sideveis og klemmer derfor. Videre er det en ulempe ved stikking av spor i boringer at arbeidet ikke kan gjennomføres kontinuerlig, slik at det oppstår dødtider ved returbevegelser. It is also known to produce grooves in bores by insertion. Insertion machines, however, must be built very robustly, while precisely this is not possible for the tool holder due to the limited space conditions in the borehole. For this reason, workpieces up to a certain size can only be machined with a tool holder, while large workpieces in which large and deep grooves are to be incorporated, require a correspondingly larger machine. In the case of long grooves to be pierced, however, it cannot be avoided that the tool, i.e. the piercing core, must protrude far, which leads to a deviation and thus to a poor surface quality. In addition, the plug core also does not protrude freely laterally and therefore pinches. Furthermore, it is a disadvantage when cutting grooves in boreholes that the work cannot be carried out continuously, so that dead times occur during return movements.

Oppfinnelsen tar sikte på å løse den oppgave å utforme en fresemaskin av den innledningsvis nevnte type slik at spor kan fremstilles kontinuerlig i boringer, især også i blindhull og med høy overflatebeskaffenhet, også ved høy-faste materialer, idet ulempene med kjente fremgangsmåter unngås. The invention aims to solve the task of designing a milling machine of the type mentioned at the outset so that grooves can be produced continuously in boreholes, especially also in blind holes and with high surface quality, also with high-strength materials, as the disadvantages of known methods are avoided.

Denne oppgave løses med fresemaskinen ifølge oppfinnelsen, med de i kravene anførte trekk. This task is solved with the milling machine according to the invention, with the features listed in the requirements.

Oppfinnelsen er vist på tegningen hvor figur 1 viser skjematisk et sideriss av en fresemaskin med et horisontalt arbeidsbord og et nedenfra, gjennom arbeidsbordet, ragende fresehode, og figur 2 viser et grunnriss av fresemaskinen på figur 1. The invention is shown in the drawing, where figure 1 schematically shows a side view of a milling machine with a horizontal work table and a milling head projecting from below, through the work table, and figure 2 shows a ground plan of the milling machine in figure 1.

Figur 1 viser et fresehode 1 som i sin frie ende 2 har anordnet et freseverktøy 3 med en dreieakse 4 som forløper i rett vinkel til fresehodets 1 lengdeakse 5. Figure 1 shows a milling head 1 which, at its free end 2, has arranged a milling tool 3 with a pivot axis 4 which runs at right angles to the longitudinal axis 5 of the milling head 1.

Dersom spor i boringer skal fremstilles i større omfang i en produksjonsbedrift, kan en dertil egnet spesialmaskin med fordel benyttes. Denne fresemaskin tjener til bearbeidning av indre kilespor i en boring i et arbeidsstykke. Her kan ikke bare rette enkle og flerkilespor, men også skrå- og spiralkilespor bearbeides. Vesentlig er at bearbeidningen foregår med et av de beskrevne fresehoder 1. Freseverktøyet 3 er eksempelvis en dobbelsidig skjærende, spiralfortannet tappfreser som kan være fremstilt av høylegert hurtigstål med beste skjærgeometri og som allikevel er et billig verktøy som lett kan vedlikeholdes. If grooves in boreholes are to be produced on a larger scale in a production company, a suitable special machine can be advantageously used. This milling machine is used for processing internal keyways in a bore in a workpiece. Here, not only straight single and multiple keyways can be machined, but also inclined and spiral keyways. It is essential that the processing takes place with one of the described milling heads 1. The milling tool 3 is, for example, a double-sided cutting, spiral-toothed end mill which can be made of high-alloy high-speed steel with the best cutting geometry and which is nevertheless an inexpensive tool that can be easily maintained.

En maskinbenk 85 på et underlag 86, eksempelvis et fundament eller verkstedgulv, bærer fire søyler 87 som på sine øvre ender bærer et arbeidsbord 88 på hvilket arbeidsstykket som skal bearbeides, legges og festes. Arbeidsbordet 88 har hensiktsmessig en deleinnretning 89, idet en åpning 90 er anordnet i arbeidsbordets 88 og deleinnretningens 89 sentrum, gjennom hvilken det stavformede fresehode 1 rager opp i arbeids-stykkets boring. A machine bench 85 on a base 86, for example a foundation or workshop floor, carries four columns 87 which at their upper ends carry a work table 88 on which the workpiece is to be machined, placed and fixed. The work table 88 suitably has a dividing device 89, an opening 90 being arranged in the center of the work table 88 and the dividing device 89, through which the rod-shaped milling head 1 protrudes into the bore of the workpiece.

Søylene 87 tjener ikke bare til opplagring av arbeidsbordet 88, men også til føring av en plattform 92 som ved hjelp av to synkront drevne gjengespindler 93, kan beveges opp og ned. Hertil tjener en motor 94, eksempelvis en elektromotor eller en hydraulisk motor, med en reduksjonsveksel 95, eksempelvis en trinnløs veksel. Reduksjonsvekselens 93 drivaksel 97 rager inn i maskinbenken 85 og er forbundet med en i denne opplagret fordelingsveksel 96, se figur 8, som omfatter en veksel 58 med koniske tannhjul, hvis ene aksel er reduksjonsvekselens 95 drivaksel 97 og hvis andre aksel 99, som ligger i rett vinkel til den første, i begge ender har en snekkeskrue 100 som via et snekkehjul 101, driver de to gjengespindler 93. The columns 87 serve not only to store the work table 88, but also to guide a platform 92 which, with the help of two synchronously driven threaded spindles 93, can be moved up and down. A motor 94, for example an electric motor or a hydraulic motor, with a reduction gear 95, for example a stepless gear, serves this purpose. The drive shaft 97 of the reduction gear 93 projects into the machine bench 85 and is connected to a distribution gear 96 stored in this, see figure 8, which comprises a gear 58 with conical gears, one shaft of which is the drive shaft 97 of the reduction gear 95 and the other shaft 99, which is located in right angle to the first, at both ends has a worm screw 100 which, via a worm wheel 101, drives the two threaded spindles 93.

En ildrift 102 er på figur 2 forbundet med reduksjons-vekselen 95 som kan overlagres med et tilleggsturtall slik at tilkjøring av fresehodet 1 til bearbeidningsstedet kan foregå med forhøyet hastighet. Gjengespindelens 93 drift kan imidlertid også gjennomføres på en annen måte, eksempelvis med en felles kjededrift eller ved hjelp av stegmotorer. Erstatning av gjengespindelen 53 med en svalehaleføring er likeledes mulig. Vesentlig er imidlertid at plattformen 92 kan utføre en egnet bevegelse som fremdriftsbevegelse for fresehodet 1 og freseverk-tøyet 3. An oil drive 102 is connected in Figure 2 to the reduction gear 95 which can be superimposed with an additional speed so that the milling head 1 can be driven to the processing site at increased speed. However, the threaded spindle 93 can also be operated in another way, for example with a common chain drive or with the help of stepper motors. Replacement of the threaded spindle 53 with a dovetail guide is also possible. It is essential, however, that the platform 92 can perform a suitable movement as a forward movement for the milling head 1 and the milling tool 3.

På plattformen 92 er et kryssbord 105 festet, som har med to håndhjul 103, 104 bevegbare fremdriftsenheter 106, 107 som tillater en bevegelse i horisontalplanet i rett vinkel til hverandre. Håndhjulene 103, 104 kan også være motordrevne, eksempelvis elektriske eller hydrauliske reguleringsanordninger. On the platform 92, a cross table 105 is attached, which has two handwheels 103, 104 movable propulsion units 106, 107 which allow a movement in the horizontal plane at right angles to each other. The handwheels 103, 104 can also be motor-driven, for example electric or hydraulic control devices.

På fremdriftsenheten 107 er fresehodet 1 festet ved hjelp av en festeflens 108, idet det dertil angrensende hus 10 er slik utformet at driften kan være anordnet i huset 10. Driften, se figur 1, er en på fremdrif tsenheten 107 festet motor 111, eksempelvis en elektrisk eller hydraulisk motor som via en vinkelveksel 109 og en drivaksel 110 er forbundet med husets 10 ytterligere drivdeler og fresehodets 1 drivdeler. On the propulsion unit 107, the milling head 1 is attached by means of a mounting flange 108, the adjacent housing 10 being designed in such a way that the drive can be arranged in the housing 10. The drive, see Figure 1, is a motor 111 attached to the propulsion unit 107, for example a electric or hydraulic motor which via an angle gear 109 and a drive shaft 110 is connected to the further drive parts of the housing 10 and the drive parts of the milling head 1.

De beskrevne fresehoder er hensiktsmessige verktøy for den på figurene beskrevne maskin hvormed, på grunn av det frie rom og arbeidsbordet 80, ikke bare små, men også meget store arbeidsstykker kan bearbeides. Fresehodene kan imidlertid også, slik det er beskrevet ovenfor, benyttes på mange andre måter, eksempelvis for innbygging i en fresemaskin, enten ved direkte forbindelse med en fresespindel eller via et hus. Vesentlig er imidlertid at fresehodets 1 stavformede hullegeme 6 utnyttes optimalt for anordning av en effektfull drivanordning. The milling heads described are appropriate tools for the machine described in the figures with which, due to the free space and the work table 80, not only small but also very large workpieces can be machined. However, the milling heads can also, as described above, be used in many other ways, for example for installation in a milling machine, either by direct connection with a milling spindle or via a housing. It is essential, however, that the rod-shaped hollow body 6 of the milling head 1 is optimally utilized for the arrangement of an effective drive device.
