Description
15' 20 25 30 35 a ;1v1o7o7-6 2 tfinningen blir också kontaktytan mindre mellan den sneda änd- ,kanten och den plana yta, som skall slipas; Genom förfarandet enligt uppfinningen kan en speciell plan- slipanordning med en andra slipskiva med drivmotor och extra inställnings- och styranordningar undvaras. Skärpningen av den enda förhandenvarande slipskivan kan företas under växling av arbetsstycke. I i I U d _ Ûppfinníngen beskrivs i det följande med en utföringsform under hänvisning till bifogade ritning, på vilken fig. l visar ett arbetsstycke och en skâlformig skiva i skärpningsläge och fig. 2 visar samma delar som fig. l, men 1 slipläge. 15 '20 25 30 35 a; 1v1o7o7-6 2 the invention also reduces the contact area between the inclined end, the edge and the flat surface to be ground; By the method according to the invention, a special planar grinding device with a second grinding wheel with drive motor and additional adjusting and control devices can be dispensed with. The sharpening of the only available grinding wheel can be performed while changing the workpiece. The invention is described in the following with an embodiment with reference to the accompanying drawing, in which Fig. 1 shows a workpiece and a shell-shaped disc in sharpening position and Fig. 2 shows the same parts as Fig. 1, but 1 grinding position.
I fig. 1 avser hänvisningssiffran 10 ett kugghjul, som är linspänt i en chuck 2 i en slipmaskin för invändig slipning.In Fig. 1, the reference numeral 10 denotes a gear which is lens-tensioned in a chuck 2 in a grinding machine for internal grinding.
Ett_centriskt hål 3 skall slipas till diametern D. En skålformig slipskiva l3 med konisk ytteryta med lutningsvinkeln d är roter- , bart lagrad i ett sliphuvud 14. Sliphuvudet är kring en mot rit- pningsplanet vinkelrät axel instållbart lagrat på det icke visa- de slipbordet, Vid den tjockare änden av slipskivan övergår dess ytteryta via en sned änkant 12 i en ändyta 18. 7 7 Slipskivans rotationsaxel och tillika-sliphuvudets längd- axel är anordnade lutande med halva konvinkeln u mot hålets längd- axel. Detta resulterar i; att en mantellinje 8 på den koniska slipskivan löper parallellt med hâlets axel och på avståndet D/2 från denna. Mantellinjen 8 är beröringslinjen mellan slip- 'skivans ytteryta och hâlets yta. Ytterytan 15 skärps genom en fast diamant 16, genom att sliphuvudet 14 med slipskivan flera gånger förs förbi diamantspetsenf Diamantspetsen står på.av- ståndet D/2 från hâlets axel och rdr sig relativt och längs man- teliinjen ja. _ i i i Vid arbetsstycket 10 slipas hålet 3 och den plana ytan ll av samma sneda yta l2 på den skålformiga slipskivan 13. I fig. l visas den skålformiga slipskivan och sliphuvudet 14 i skårpnings- läget. Den sneda ytan 12 och ändytan 18 skärps gemensamt genom_ en profilerad skärpningsrulle 19. Denna är drivbart lagrad på I en tvärslid 20 för rotation kring sin längdaxel¿ Skärpnings- rullen visas i arbetsläget med streckade linjer. Diamanten 16 10 15 20 25 7710707-6 kan vara fäst vid en icke visad svängarm.A_centric hole 3 is to be ground to a diameter D. A cup-shaped grinding wheel 13 with a conical outer surface with the angle of inclination d is rotatably mounted in a grinding head 14. The grinding head is adjustably mounted on the grinding table (not shown) about an axis perpendicular to the drawing plane. At the thicker end of the grinding wheel, its outer surface merges via an oblique end edge 12 into an end surface 18. The axis of rotation of the grinding wheel and also the longitudinal axis of the grinding head are arranged inclined with half the cone angle u to the longitudinal axis of the hole. This results in; that a jacket line 8 on the conical grinding wheel runs parallel to the axis of the hollow and at the distance D / 2 therefrom. The jacket line 8 is the line of contact between the outer surface of the grinding wheel and the surface of the hole. The outer surface 15 is sharpened by a solid diamond 16, by passing the grinding head 14 with the grinding wheel several times past the diamond tip. The diamond tip is at a distance D / 2 from the axis of the hole and moves relatively and along the jacket line. At the workpiece 10, the hole 3 and the flat surface 11 are ground by the same oblique surface 12 on the cup-shaped grinding wheel 13. In Fig. 1, the cup-shaped grinding wheel and the grinding head 14 are shown in the sharpening position. The inclined surface 12 and the end surface 18 are jointly sharpened by a profiled sharpening roller 19. This is drivably mounted on a transverse slide 20 for rotation about its longitudinal axis. The sharpening roller is shown in the working position with dashed lines. The diamond 16 10 15 20 25 7710707-6 may be attached to a pivot arm (not shown).
Efter skärpning av slipskivans ytor 15, 12 och 18 förs slip- skivan av sliphuvudet 14 först i den vågräta pilens riktning (fig. l) åt vänster och hålet 3 slipas genom den sneda ytan 12.After sharpening the surfaces 15, 12 and 18 of the grinding wheel, the grinding wheel is first moved by the grinding head 14 in the direction of the horizontal arrow (Fig. 1) to the left and the hole 3 is ground through the oblique surface 12.
Denna avverkar vid en enda genomgång av slipskivan genom arbets- stycket hela slipmånen s. Därefter återförs slipskivan axiellt åt höger och tvärmatningen i riktning av den i fig. 2 visade _ pilen inkopplas. Fig. 2 visar slipskivan matad ungefär halvvägs.In a single pass of the grinding wheel through the workpiece, it cuts the entire grinding moon s. Then the grinding wheel is returned axially to the right and the transverse feed in the direction of the arrow shown in Fig. 2 is switched on. Fig. 2 shows the grinding wheel fed approximately halfway.
Härvid slipas arbetsstyckets plana yta ll av samma sneda yta 12, som slipade hålet. Efter slipningen av den plana ytan 11 dras bordet med sliphuvudet 14 mot pilriktningen tillbaka till ställ- ningen för hålslipning, förs axiellt till det i fig; 1 visade utgångsläget samt skärps av profilskärpningsrullen 19. Den där- vid i axiell riktning tillryggalagda vägen är skärpningsmåttet kortare än det alltid lika avståndet a mellan skärpningsrullen 19 och den färdigslipade plana ytan ll.In this case, the flat surface ll of the workpiece is ground by the same oblique surface 12 which ground the hole. After grinding the flat surface 11, the table with the grinding head 14 is pulled back to the position of hole grinding in the direction of the arrow, is moved axially to that in fig. 1 and is sharpened by the profile sharpening roller 19. The path then traveled in the axial direction is the sharpening dimension shorter than the always equal distance a between the sharpening roller 19 and the finished ground surface 11.
Det beskrivna arbetsförloppet kan valfritt även ske i omvänd ordning, dvs först slipas den plana ytan och därefter hålet.The described work process can optionally also take place in reverse order, ie first the flat surface is sanded and then the hole.
Under skärpningen växlas arbetsstycket 10. Därefter förs bordet med sliphuvudet 14 och slipskivan med snabbmatning till läge framför hålet 3, vilket därefter med matningshastighet sli- pas av den sneda kanten 12. Ytterytan 15 tar icke del i slip- ningen. Den justeras därför bara en gång, nämligen vid insättan- de av en ny slipskiva, av diamanten 16, vars spets ligger på den gemensamma beröringslinjen 8 mellan det färdigslipade hålet (D) och slipskivans ytteryta 15.During sharpening, the workpiece 10 is shifted. The table with the grinding head 14 and the grinding wheel are then moved with rapid feed to a position in front of the hole 3, which is then ground by the oblique edge 12 at feed speed. The outer surface 15 does not take part in grinding. It is therefore adjusted only once, namely when inserting a new grinding wheel, of the diamond 16, the tip of which lies on the common line of contact 8 between the finished ground hole (D) and the outer surface 15 of the grinding wheel.
