Abstract

The invention concerns a support for the grinding of tools by means of a grindstone, whereby the tool can be fixed relative to the rotary axis of the gridstone by means of fixed-tension devices which can be moved and rotated in a plane which basically coincides with the plane of the stone. <IMAGE>

Description

15 -20 25 30 7809980-1 bärande bygeln, erhålles samtidigt med den fasta uppspänningen av verktyget en stor rörelsefrihet av detta vid slipningen. 15 -20 25 30 7809980-1 bearing bracket, a large freedom of movement is obtained at the same time as the fixed clamping of the tool during grinding.

Denna rörelsefrihet är möjlig utan att därför stödet behöver bli oproportionerligt stort. 1 Uppfinningen kommer närmare att beskrivas i form av ett exem- Kpel under hänvisning till ritningen, vari fig 1 visar stödet sett- från sidan, fig 2 visar en del av stödet och fig 3 visar stödet sett från änden. - 1 betecknar en första U-formad del,.vars liv 2 är avsett att l [kunna fästas vid slipstenens fundament, Delens 1 skänklar 3 upp- lbär en vid skänklarna fastsatt axel 4, vilken vid monteringen är šavsedd att ligga parallellt med slípstenens vridaxel. En-andra' 1U-formad del 5 är anordnad att medelst hål i sina skänklar 6 ' kunna vridas och förskjutas på axeln 4. Som framgår av fig 1 är šaxeln 4 förlängd utanför ena skänkeln hos den första delen 1 och fär ena skänkeln 6 hos den andra delen förlagd mellan de två ïskänklarna 3.This freedom of movement is possible without therefore the support needs to be disproportionately large. The invention will be described in more detail in the form of an example with reference to the drawing, in which Fig. 1 shows the support seen from the side, Fig. 2 shows a part of the support and Fig. 3 shows the support seen from the end. 1 denotes a first U-shaped part, the web 2 of which is intended to be attached to the foundation of the grindstone. . A second '1U-shaped part 5 is arranged so that by means of holes in its legs 6' it can be rotated and displaced on the shaft 4. As can be seen from Fig. 1, the shaft 4 is extended outside one leg of the first part 1 and has one leg 6 of the second part located between the two ïskänklaren 3.

Livet 7 hos delen 5 uppvisar en första stödyta och uppbär medelst två gängade skruvar 8 en på dessa förskjutbar press: platta 9, vilken medelst skruvtryckfjädrar 10 strävar att fjär- ma sig från den första stödytan. Medelst muttrar, lämpligen lstjärnvred 11, kan pressplattan 9 tryckas mot den första stöd- ytan. Pressplattan 9 uppvisar likaså en stödyta, vänd mot den första stödytan. Som närmare framgår av fig 2, som visar delen 5 uppifrån, är denna stödytan utformad med ett försänkt parti 12, varvid de parallellt med slipstenens vridaxel förlöpande kan- terna hos stödytan bildar förhöjningar 13. Pressplattan 9 är på samma sätt försedd med ett motsvarande försänkt parti 14, bildan- de förhöjda kanter mitt emot kanterna 13.The web 7 of the part 5 has a first support surface and supports by means of two threaded screws 8 a press displaceable thereon: plate 9, which by means of helical compression springs 10 strives to move away from the first support surface. By means of nuts, suitably star knob 11, the press plate 9 can be pressed against the first support surface. The press plate 9 also has a support surface, facing the first support surface. As can be seen in more detail from Fig. 2, which shows the part 5 from above, this support surface is formed with a recessed portion 12, the edges of the support surface extending parallel to the axis of rotation of the grindstone forming elevations 13. The press plate 9 is similarly provided with a corresponding recessed portion 14, forming raised edges opposite the edges 13.

En styrklack 15 är anordnad på var sin sida av resp kant eller förhöjning 13 vid ena änden av delen 5 men innanför skru- varna 8. Styrklackarna ligger på en linje vinkelrätt mot axeln 4 och på sådant avstånd från varandra, att pressplattan 9 kan röra sig mellan dem. '7809980-1 Verktyget, som skall slipas, skjuts in på plats mellan stöd- ytorna och skruvas med hjälp av vreden 11 pressplattan 9 fast mot verktyget och delen S. Genom att bringa verktgyet till an- liggning mot styrklackarna 15 erhålles en exakt inriktning av verktyget i förhållande till slipstenen. Genom att delen 5 är vrídbar kan nu verktyget tryckas mot slipstenen och samtidigt föras fram och åter utefter dennas periferí, därmed bidragande till en jämn slipning av verktyget liksom samtidigt en jämn av- nötning av stenen. ____.........___-.._..-_A guide lug 15 is arranged on each side of the respective edge or ridge 13 at one end of the part 5 but inside the screws 8. The guide lugs lie on a line perpendicular to the shaft 4 and at such a distance from each other that the press plate 9 can move between them. The tool to be ground is pushed into place between the support surfaces and screwed by means of the knobs 11 to the press plate 9 fixed to the tool and the part S. By bringing the tool into abutment against the guide lugs 15, an exact alignment of the tool in relation to the grindstone. Because the part 5 is rotatable, the tool can now be pressed against the grindstone and at the same time be moved back and forth along its periphery, thereby contributing to an even grinding of the tool as well as at the same time an even wear of the stone. ____.........___-.._..-_

Claims

'7809980-1 in Patent Claims

Aid for grinding tools by means of a grindstone and consisting of a first U-shaped part (1) whose web (2) is intended to be able to be attached to the foundation of the grindstone, wherein the legs (3) of the first part (1) support a shaft (4) on which likewise with its legs (6) a second U-shaped part (5) is pivotally mounted, whose web (7) facing away from the first part has a first support surface and carries a press plate which can be pressed against the first support surface. (9) having a second support surface, characterized> in that the facing first and second support surfaces are formed by the edges (13) parallel to the pivot axis (4) of the life of the second part (5), elevated relative to the between the edges lying part of the waist, resp. of the edges of the press plate (9) also parallel to the pivot axis (U) are raised relative to the part of the press plate lying between the edges, the shaft (4) being arranged to extend beyond one of the legs of the first part (1). and that the second part (5) is mounted on the shaft (H) with one leg between the legs of the first part and with the other leg on the part of the shaft (4) which extends beyond the legs of the first part (1).

Support according to claim 1, characterized in that the first support surface is provided with two guide lugs (15) arranged at each edge of the support surface and in a line substantially perpendicular to the axis (4) and at such a distance from each other that the press plate ( 9) _ can move towards the first support surface and between the guide lugs (15).

Support according to Claim 1 or 2, characterized in that the press plate (9) can be pressed against the first support surface by means of two nuts (11) threaded on screws (8) and in that a helical compression spring (10) is arranged around resp. screw between the support surfaces.
