Opfindelsen angår en honeværktøj af den i krav 1' s indledning angivne art. Et sådant honeværktøj er beskrevet i US-patentskrift nr. 3 384 915. Ved brug af dette kendte honeværktøj har det vist sig, at dets slibende kugler ikke forbliver sikkert fæstet til børsternes eller bærestavenes ender. De i nævnte US-patentskrift beskrevne bærestave kræver, at der under honeværktøjets fremstilling tilvejebringes et sammenhængende endeparti med øgede dimensioner, for at der kan påføres bærestavenes endepartier et bindemiddel for slibepartiklerne. En sådan fremstilling er kompliceret, og omkostningerne ved denne øges yderligere derved, at alle bærestaves endepartier skal opvarmes, for at disses yderdimensioner kan øges. Desuden er ved det kendte honeværktøj de slibende partikler monteret på bærestavenes øgede endepartier ved hjælp af et bindemiddel, f.eks. en epoxyharpiks. Erfaringen i praksis har imidlertid vist, at et bindemiddel, der er velegnet til at bære slibende partikler i sin masse, ikke er særlig velegnet til at fæste bindemidlet sikkert til bærestavenes øgede endepartier.The invention relates to a female tool of the kind specified in the preamble of claim 1. Such a female tool is disclosed in U.S. Patent No. 3,384,915. Using this known female tool, it has been found that its abrasive balls do not remain securely attached to the ends of the brushes or carriers. The supporting rods described in said US patent require that during the manufacture of the female tool, a continuous end portion of increased dimensions be provided in order to apply a binder for the abrasive particles to the end portions of the support rods. Such manufacturing is complicated and the cost of this is further increased by the fact that all the end portions of the support rod need to be heated in order to increase their outer dimensions. Furthermore, in the known honing tool, the abrasive particles are mounted on the increased end portions of the support rods by means of a binder, e.g. and an epoxy resin. Experience in practice, however, has shown that a binder suitable for carrying abrasive particles in its mass is not very suitable for securely attaching the binder to the increased end portions of the support rods.
Der har således været et behov for fremstilling af honeværktøj er, som ikke er behæftet med ulemperne ved det i US-patentskrift nr. 3 384 915 beskrevne honeværktøj.Thus, there has been a need for the manufacture of honing tools which do not suffer from the disadvantages of the honing tool described in U.S. Patent No. 3,384,915.
I US-patentskrift nr. 3 696 563 beskrives en anden type honeværktøj, hvis slibende partikler ved hjælp af et metallisk bindemiddel er fæstet til bærestavenes endepartier. Disse bærestave er enten metaltråde eller formstofstave. Man har her til fremstilling af honeværktøj et benyttet forskellige teknikker såsom flammesprøjtning og neddykning i smeltet metal. Den fra US-patentskrift nr.U.S. Patent No. 3,696,563 discloses another type of honing tool whose abrasive particles are attached to the end portions of the carrier by means of a metallic binder. These carrier rods are either metal wires or plastic rods. Here, various techniques such as flame spraying and immersion in molten metal have been used in the manufacture of honing tools. The U.S. Pat.
3 696 563 kendte teknik er således vidt forskellig fra den med foreliggende opfindelse nærmest beslægtede kendte teknik ifølge US-patentskrift nr. 3 384 915.3,696,563 prior art is thus far different from the prior art closely related to the present invention according to US Patent No. 3,384,915.

Den foreliggende opfindelse tager sigte på at afhjælpe de ovennævnte mangler og vanskeligheder, og dette opnås ved det i krav l's kendetegnende del angivne.The present invention aims to overcome the aforementioned shortcomings and difficulties, and this is achieved by the characterizing part of claim 1.
Erfaringen i praksis har vist, at slibekuglerne ved hone-værktøjet ifølge opfindelsen er sikkert, permanent fæstet til bærestavenes endepartier.Experience in practice has shown that the abrasive balls of the hone tool according to the invention are secure, permanently attached to the end portions of the support rods.
I det følgende forklares opfindelsen nærmere ved hjælp af tegningen, hvor fig. 1 er et snit efter linien 1-1 i fig. 2 i en udførelsesform for honeværketøjet ifølge opfindelsen, fig. 2 viser honeværktøjet, set i retning af dobbeltpilen 2-2 i fig. 1, fig. 3 viser honeværktøjet perspektivisk, fig. 4 viser endepartiet af en bærestav, set fra siden, fig. 5 er et snit i bærestavens endeparti med en belægning og klar til anbringelse af en slibekugle, fig. 5A er et snit svarende til fig. 5 og illustrerer et trin ved fremstillingen af det belagte endeparti i fig.In the following, the invention is explained in more detail with reference to the drawing, in which fig. 1 is a sectional view taken along line 1-1 of FIG. 2 in one embodiment of the female tool according to the invention; FIG. 2 shows the female tool, seen in the direction of the double arrow 2-2 in FIG. 1, FIG. 3 is a perspective view of the female tool; FIG. 4 is a side view of the end portion of a support rod; FIG. 5 is a sectional view of the end portion of the support rod with a coating and ready for application of a grinding ball; FIG. 5A is a section similar to FIG. 5, illustrating a step in the preparation of the coated end portion of FIG.

3 fig. 8 svarende til fig. 6 viser en tredje udførelsesform, fig. 9 svarende til fig. 6 viser en fjerde udførelsesform for et stavendeparti med slibekugle, fig. 10 skematisk og set fra siden, delvis i snit viser en udførelsesform for honeværktøjet ifølge opfindelsen inden dettes indføring i en boring, hvis diameter er mindre end honeværktøjets oprindelige ydre diameter, og fig. 11 svarer til fig. 10, men viser værktøjet efter dets tvangsmæssige indføring i boringen ved hjælp af et i fig. 11 vist apparat til rotering af værktøjet.3 FIG. 8 corresponding to FIG. 6 shows a third embodiment; FIG. 9 corresponding to FIG. 6 shows a fourth embodiment of a rod end with abrasive ball; FIG. 10 is a diagrammatic side view, partly in section, of an embodiment of the female tool according to the invention prior to its introduction into a bore whose diameter is smaller than the original outer diameter of the female tool; and FIG. 11 corresponds to FIG. 10, but shows the tool after its forced insertion into the bore by means of a device shown in FIG. 11 is shown for rotating the tool.
Tegningens figurer 1 til 3, 10 og 11 viser et roterende honeværktøj 20 med et til en bærer 24 fastgjort antal bærestave 22. Bæreren 24 er en snoet dobbelttråd 26, og et indre parti 28 af hver bærestav 22 eller et midterparti af en dobbeltstav er forankret i bæreren 24. Hver bærestav 22 har et ydre skaftformet parti 22S med en endeflade 22T, fig. 4, og er fremstillet af et elastisk termoplastisk materiale, f.eks. polyamid (nylon). Hver bærestav 22 strækker sig radialt ud fra den snoede tråd 26.Figures 1 to 3, 10 and 11 of the drawing show a rotating female tool 20 having a number of supporting rods 22. A carrier 24 is a twisted double strand 26 and an inner portion 28 of each supporting rod 22 or a central portion of a double rod is anchored. in the carrier 24. Each carrier 22 has an outer shaft-shaped portion 22S with an end surface 22T. 4, and is made of an elastic thermoplastic material, e.g. polyamide (nylon). Each support rod 22 extends radially from the twisted wire 26.
På hver bærestav 22's radialt ydre endeparti 22S er fastgjort en slibekugle 30. Da værktøjet ifølge opfindelsen primært er beregnet til drevet rotation til honing af en boring eller en cylindrisk fordybning, er alle slibekugler 30' s midtpunkter beliggende på en tænkt cirkulærcylindrisk flade. Kuglerne 30 kan let undvige radialt indadtil, når værktøjet indføres i en boring med noget mindre diameter end den omtalte tænkte cylinderflades, som anskueliggjort i fig. 11.On the radially outer end portion 22S of each support rod 22 is secured a grinding ball 30. Since the tool according to the invention is intended primarily for driven rotation for honing a bore or a cylindrical recess, all the centers of the grinding balls 30 are located on a contemplated circular cylindrical surface. The balls 30 can easily avoid radially inwardly when the tool is inserted into a bore of somewhat smaller diameter than the aforementioned imagined cylinder surface, as illustrated in FIG. 11th
Hver kugle 30 er fæstnet på sin bærestavs ydre endeparti 22S på en sådan måde, at størstedelen af bærestaven erEach ball 30 is attached to the outer end portion 22S of its support rod in such a way that the majority of the support rod is

4 fri for nogen ydre belægning. Hver kugle 30 består af et honemateriale 36 i form af slibepartikler og et bindemiddel 34 mellem disse. Til fastgørelse af slibekuglerne 30 på stavendepartierne 22S påføres der endepartierne først en limbelægning, som skal styrke forbindelsen mellem kuglen og bærestaven. Som lim anvendes en syntetisk tokomponent harpikslim 35, fig. 5, der hærdes. Dernæst dyppes stavendepartierne 22S med den hærdede lim 35 i et til at begynde med flydende limbindemiddel 34, som hensigtsmæssigt er anbragt i en flad beholder.4 free of any exterior coating. Each ball 30 consists of a female material 36 in the form of abrasive particles and a binder 34 therebetween. For attaching the abrasive balls 30 to the rod end portions 22S, the end portions are first applied to an adhesive coating which is intended to strengthen the connection between the ball and the support rod. As a glue is used a synthetic two-component resin adhesive 35, fig. 5 which is cured. Next, the stick portions 22S are dipped with the cured adhesive 35 in one, initially with liquid adhesive binder 34 which is conveniently placed in a flat container.
Inden bindemidlet 34's hærdning kan bærestavenes belagte ydre endepartier dyppes i fine slibepartikler 36 til dannelse af slibekuglerne 30, fig- 6, som dernæst hærdes på stedet, d.v.s. på hver sin bærestavs ydre endeparti 22S.Prior to the curing of the binder 34, the coated outer end portions of the support rods may be dipped into fine abrasive particles 36 to form the abrasive balls 30, FIG. 6, which are then cured on site, i.e. on the outer end portion 22S of each carrier rod.
Limen 35 tjener som mekanisk bro mellem selve stavendepartiet og slibekuglerne 30's bindemiddel 34, der kan være en epoxyharpiks, som lufthærder inden for 24 timer ved en temperatur på ca. 25°C.The adhesive 35 serves as a mechanical bridge between the rod portion itself and the binder 34 of the abrasive balls 30, which may be an epoxy resin which will cure within 24 hours at a temperature of approx. 25 ° C.
Bindemidlet 34 kan dog også inden for tilnærmelsesvis fire timer hærdes ved en temperatur på mellem 93 og 121°C.However, the binder 34 may also cure within approximately four hours at a temperature of between 93 and 121 ° C.
Slibepartiklerne 36 kan bestå af wolframcarbid, carborundum eller et andet til formålet velegnet, meget hård materiale.The abrasive particles 36 may consist of tungsten carbide, carborundum or other suitable very hard material.
Limen 35 er en tokomponent-resorcinol-formaldehydharpiks med en første komponent, der i flydende form og ved stuetemperatur kan påføres bærestavenes endepartier, og en hærdekomponent med et additiv til hærdning af limen på stedet, jfr, fig. 5A og 5B.The adhesive 35 is a two-component resorcinol-formaldehyde resin having a first component which can be applied in liquid form and at room temperature to the end portions of the support rods, and a hardening component with an additive for curing the adhesive on site, cf. 5A and 5B.
I fig. 5A er limens første komponent betegnet med 37’.In FIG. 5A is the first component of the adhesive designated 37 '.
Denne komponent er en delvis kondenseret resorcinol-formaldehyd-harpiks i en alkohol-vand-opløsning. EfterThis component is a partially condensed resorcinol-formaldehyde resin in an alcohol-water solution. After

5 denne første komponents påføring på bærestavenes endepartier tilsættes den anden komponent indbefattende en hærder i form af et pulver bestående af paraformaldehyd og et cellulose-fyldmateriale. Dette andet trin er anskue-liggjort i fig. 5B, hvor hærderen er betegnet med 37".In the application of this first component to the end portions of the support rods, the second component is added including a hardener in the form of a powder consisting of paraformaldehyde and a cellulose filler. This second step is illustrated in FIG. 5B, wherein the hardener is designated 37 ".
Efter tilsætningen af limens anden komponent 37" hærder tokomponent-resorcinol-formaldehydharpiks-limen 35 med en meget stærk vedhængning til såvel bærestavenes endeparti 22S som til det dernæst påførte og derefter hærdede epoxy-bindemateriale 34 i den ydre belægning 32, som danner slibekuglen 30. Tokomponentlimen 35's affinitet til bærestave i form af nylonbørster og til slibekuglerne 30* s bindemiddel 34 er tilstrækkelig stor til at forhindre afbrækning eller afskalning af væsentlige dele af slibekuglerne 30 selv under hårde arbejdsbetingelser som vist i fig. 11. Bindemidlet 34 slides efterhånden ned, idet det er blødere end det bearbejdede emne, så at slibepartiklerne 36 rager tilstrækkelig langt ud fra bindematerialet 34 til at være effektive i hele værktøjet 20’ s levetid. Hver slibekugle 30 er ved hjælp af limen 35 forbundet med bærestavenes endeparti 22s på en sådan måde, at bærestavenes elasticitet bevares uændret.After the addition of the second component 37 "of the adhesive, the two-component resorcinol-formaldehyde resin adhesive 35 cures with a very strong adhesion to both the end portion 22S of the support rods and to the then applied and then cured epoxy bonding material 34 in the outer coating 32 forming the abrasive ball 30. The affinity of two-component adhesive 35 for nylon bristles and for the abrasive balls 30 * s binder 34 is sufficiently large to prevent the breaking or peeling of substantial portions of the abrasive balls 30 even under harsh working conditions as shown in Fig. 11. The binder 34 gradually wears off as it is softer than the machined workpiece so that the abrasive particles 36 extend sufficiently far from the binder material 34 to be effective throughout the life of the tool 20. Each abrasive ball 30 is connected to the end portion 22s of the support rods in such a manner. that the elasticity of the support rods is kept unchanged.
Forsøg har vist, at bærestavenes bøjelighed er mindst dobbelt så stor som bøjeligheden af en bærestav, som er forsynet med en belægning af lim 35 i sin samlede længde.Tests have shown that the flexibility of the support rods is at least twice as much as the flexibility of a support rod provided with a coating of glue 35 in its total length.
Fig. 7 viser en ændret udførelsesform med i det væsentlige samme tokomponentlim 35a som ved den i det foregående beskrevne udførelsesform. Det slibekuglen 30a dannende overtræk har imidlertid flere lag 32a hvert indbefattende et bindemiddel 34a og slibepartikler 36a, som er bundet til mindst én mellemliggende flade 38. Der fås på denne måde en lamineret slibekugle 30a, som regel bestående af det samme bindemiddel og de samme slibepartikler som ved den først beskrevne udførelsesform. Kuglélagenes grænseflader muliggør fremstillingen af en lamineret slibekugleFIG. 7 shows a modified embodiment having substantially the same two-component adhesive 35a as in the embodiment described above. However, the abrasive ball 30a coating has several layers 32a each including a binder 34a and abrasive particles 36a which are bonded to at least one intermediate surface 38. In this way, a laminated abrasive ball 30a, usually consisting of the same binder and the same abrasive particles, is obtained. as in the first embodiment described. The ball joint interfaces enable the manufacture of a laminated abrasive ball

6 med større diameter end ved den først beskrevne udførelsesform.6 with a larger diameter than in the first described embodiment.
fig. 8 viser en udførelsesform, hvor overtrækket 32b på slibekuglen 30b afviger fra det i fig. 6 viste derved, at bindemidlet 34b og slibepartiklerne 36b er blandet, inden de påføres tokomponent-limen 35b. Overtrækket 32b kan tilvejebringes ved, at bindemidlet 34b og partiklerne 36b blandes i en beholder, umiddelbart inden de påføres bærestavenes med limen 35b forsynede endeparti 22b.FIG. 8 shows an embodiment in which the coating 32b of the grinding ball 30b differs from that of FIG. 6 thereby showed that the binder 34b and the abrasive particles 36b are mixed before being applied to the two-component adhesive 35b. The coating 32b can be provided by mixing the binder 34b and the particles 36b into a container immediately before applying the end portion 22b of the carrier rods provided with the adhesive 35b.
Fig. 9 viser en yderligere udførelsesform, der hovedsageligt adskiller sig fra de hidtil beskrevne ved, at selve slibekuglen 30c omslutter en udvidet, kugleformet del 22E af bærestavens endeparti 22c. På denne måde tilvejebringes der en større overflade for limen 35c, og der kræves kun en tilsvarende reduceret mængde bindemiddel 34c til dannelse af en slibekugle 30c af samme størrelse som slibekuglen i fig. 6.FIG. 9 shows a further embodiment which differs substantially from those previously described in that the abrasive ball 30c itself encloses an expanded, spherical portion 22E of the end portion 22c of the support rod. In this way, a larger surface is provided for the glue 35c and only a correspondingly reduced amount of binder 34c is required to form a grinding ball 30c of the same size as the grinding ball of FIG. 6th
Fig. 10 og 11 anskueliggør det roterende honeværktøjets selvcentrerende og selvdimensionerende virkning. Et emne 40, der skal bearbejdes, er vist i tværsnit og har en boring med en cylindrisk væg 42, som skal hones. Honeværk-tøjet 20's ydre diameter er større end boringens, så at det roterende honeværktøj 20 kun kan tvinges ind i boringen ved udnyttelsen af bærestavenes elasticitet.FIG. 10 and 11 illustrate the self-centering and self-dimensioning effect of the rotary female tool. A workpiece 40 to be machined is shown in cross-section and has a bore with a cylindrical wall 42 to be honed. The outer diameter of the female tool 20 is larger than that of the bore, so that the rotary female tool 20 can only be forced into the bore by utilizing the elasticity of the carrier rods.
