Description

1 Slipverktygshallaranordning Den foreliggande uppfinningen avser en anordning vid roterbar skivformig hallare for slipverktyg innefattande slipsegment lasgOrbart fastsattbara i radiellt riktade avsmalnande spar i ifragavarande hallare. The present invention relates to a device for rotatable disc-shaped holders for grinding tools comprising grinding segments weldable in radially directed tapered grooves in the respective holders.

Det foreligger problem att sdkert kvarhalla slipsegment som fastgares i roterbara slipskivehallare av ovan angivet slag, speciellt nar maskinen är avstangd och transporteras mellan olika arbetsplatser. There is a problem with securely holding grinding segments which are fastened in rotatable grinding wheel holders of the type specified above, especially when the machine is switched off and transported between different workplaces.

Exempelvis kan slipsegmenten forskjutas oanskat i riktning in mot hallarens centrum om slipsegmenten utsattes for ovarsam hantering eller om de slar i nagot fast foremal pa marken, t.ex. en trottoarsten nar maskinen kares pa marken till/fran transportfordon. Vid sadana tillfallen kan kilverkan mellan slipsegmenten och de kilformade sparen i hallaren minska och i varsta fall helt forsvinna, varvid de slapper fran varandra och slipsegmentet lossnar och kan gá forlorat, vilket betyder att en hel sats nya slipsegment maste inforskaffas och ersatta saval det fOrlorade slipsegmentet som de ovriga kvarsittande slipsegmenten. Det är viktigt att slipsegmenten slites jamnt for att bl.a. undvika obalans pa skivan men dven for att undvika ojamn slipning av underlaget. De sagda slipsegmenten är anordnade att slitas ned vasentligen i niva med slipski- vans frontyta i vilka de radiella sparen är frdsta I. For example, the tie segments can be displaced undetected in the direction towards the center of the hall if the tie segments are subjected to careless handling or if they strike a solid object on the ground, e.g. a pavement stone when the machine is driven on the ground to / from transport vehicles. In such cases, the wedge action between the tie segments and the wedge-shaped grooves in the holder can decrease and in any case disappear completely, whereby they become detached and the tie segment becomes detached and can be lost, which means that a whole batch of new tie segments must be procured and replace the lost tie segment. as the other remaining tie segments. It is important that the tie segments wear evenly in order to e.g. avoid imbalance on the disc but also to avoid uneven sanding of the substrate. The said grinding segments are arranged to be worn down substantially at the level of the front surface of the grinding wheel in which the radial grooves are first I.

Genom JP 11-151675 är kant att fasthalla slipskivesegment med hjalp av ett omslutande band. Detta galler slipskivesegment som ãr inforda i radiella kilformiga spar utifran skivans omkrets. Through JP 11-151675, the edge is to hold the grinding wheel segment with the aid of an enclosing band. This applies to grinding wheel segments which are inserted in radial wedge-shaped grooves from the circumference of the wheel.

Enligt CH 523746 avses att med svangbar lashasp kvarhalla slipsegmenten i tillhorande kilformiga radiella spar. 2 Huvudandamalet med den foreliggande uppfinningen ãr darfor i forsta hand att bl.a. losa det ovan angivna problemet med oavsiktlig lossgaring av slipskivesegmenten fran slipskivan, och med enkla och val fun- gerande medel. According to CH 523746, it is intended to retain the tie segments in the associated wedge-shaped radial grooves with pivotable lash spindle. The main object of the present invention is therefore primarily that i.a. solve the above-mentioned problem with unintentional detachment of the grinding wheel segments from the grinding wheel, and with simple and selective means.

Ddrigenom ãr sagda magnet 6 som mottages i sagda urtagning 9 anordnad att forhindra tillbakaforing av ifragavarande slipseg- ment 3, som mottages i tillhorande radiella tillharande spar 5 med dess med laxstjdrtformat tvdrsnitt formade bottenparti 10, och kongruent till tillharande spar 5. A recess 9, which is the bellows in the rear inner Spirit 5A of the respective retaining groove 5, at the center of the groove, i.e. said said spar 5, is shaped to the 4 associated magnet 6 so as to be able to receive said magnet 6, weldable in designed recess 9, in holder 2. Thereby said magnet 6 received in said recess 9 is arranged to prevent return of the tie segment in question. ment 3, which is received in associated radial associated grooves 5 with its salmon tail-shaped cross-section formed bottom portion 10, and congruent to associated grooves 5.

Djupet pa sagda urtagning 9 är sa valt och hojden pa magneten 6 är anpassad sá att ifragavarande i uttagningen 9 mottagen magnet 6 strdcker sig till en niva som overstiger slipsegmentets 3 bottenparti, samt att sagda urtagning 9 är tvdrstalld fasthallningssparet 5 i tillhorande del av hallaren 2. The depth of said recess 9 is so chosen and the height of the magnet 6 is adjusted so that the magnet 6 received in the recess 9 extends to a level which exceeds the bottom portion of the tie segment 3, and that said recess 9 is the transverse retaining pair 5 in the associated part of the holder 2 .

Enligt utforandet av uppfinningen, som visas i Fig 1-5, är placeringen av magneterna 7-8 anordnade i parvisa urtagningar 11, 12, som helt eller delvis är dolda av i mellanbelAget radiellt riktat fasthallande spar 5 fdstat slipsegment 3. Sagda urtagningar 11, 12, som dr anordnade att mottaga var sin magnet 7, 8, är forman- passade till sagda magneter 7, 8 och resp urtagning 11, 12 uppvisar ett djup som vasentligen Overensstdmmer med tillhorande magnets 7, 8 tjocklek. Urtagningarna 11, 12 är belagna vid hallarens 2 periferi med en urtagning 11, 12 beldgen pa var sin sida am sparet 5. Magneterna 7, 8 och ddrtill horande kongruent-/a urtagning 9/urtagningar 11,12 uppvisar ldmpligen fyrkantform och foretrddesvis dá rektanguldr form. According to the embodiment of the invention, shown in Figs. 1-5, the placement of the magnets 7-8 is arranged in paired recesses 11, 12, which are wholly or partly hidden by radially directed retaining grooves 5 in the former tie segment 3. 12, which are arranged to receive their respective magnets 7, 8, are shaped to said magnets 7, 8 and the respective recesses 11, 12 have a depth which essentially corresponds to the thickness of the associated magnet 7, 8. The recesses 11, 12 are located at the periphery of the holder 2 with a recess 11, 12 on each side of the spare 5. The magnets 7, 8 and the associated congruent recess 9 / recesses 11, 12 have a generally square shape and preferably rectangular gold. form.

Ett eller flera halrum 13 r beldget/belAgna vid kanten av sagda urtagning 9; 11, 12 far grepp- samverkan mellan en i urtagningen 9; 11, 12 mottagen magnet 6-8 och kanten pa sagda urtagning, exempelvis med en kniv, skruvmejsel eller annat verktyg. One or more cavities 13 are beldget / belAgna at the edge of said recess 9; 11, 12 have a gripping interaction between one in the recess 9; 11, 12 received magnet 6-8 and the edge of said recess, for example with a knife, screwdriver or other tool.

S Borttagning av slipsegment enligt utforandet av forsta exemplet sker genom att man med t.ex. en kniv petar loss magneten 6 och sá att slipsegmentet 3 kan forskjutas i tillhorande spar 5 och darefter kan lyftas loss fran sparet 5, for eventuellt byte etc. S Removal of tie segments according to the design of the first example takes place by using e.g. a knife pokes the magnet 6 loose and so that the tie segment 3 can be displaced in the associated groove 5 and then can be lifted loose from the groove 5, for possible replacement etc.

Enligt det andra exemplet behover magneterna 11, 12 ej tagas bort fran hallaren 2 utan man greppar i stallet hart i slipsegmenten 3 och later forskjuta dem radiellt i riktning in mot hallarens centrum 2B sá att greppet frail magneterna 11, 12 slapper och slipsegmenten 3 darefter lossnar fran hallaren. According to the second example, the magnets 11, 12 do not have to be removed from the holder 2, but the handle is gripped hard in the tie segments 3 and allowed to slide radially towards the center 2B of the holder so that the grip frail the magnets 11, 12 relaxes and the tie segments 3 then come loose. from the hall.

I omvand ordning satter man fast slipsegmenten 3 pa hallaren 2. In reverse order, fasten the tie segments 3 to the holder 2.

Naturligtvis bestar bade hallaren 2 och 15 slipsegmenten 3, Atminstone dess fastgorande delar, som samverkar med magneterna 6; 7, 8, av metall eller annat material som magneter faster pa. Of course, both the holder 2 and 15 consist of the tie segments 3, At least its fastening parts, which cooperate with the magnets 6; 7, 8, of metal or other material to which magnets adhere.
