Abstract

Navrhnuté technické rleSenia aa týká brúeleceho péaaa brúeneho kotúča pre bezhroté brúeky upraveného pre zdokonalenie geometrického tvaru obrobku. Podatatou rieSenia Je vytvořením brúeleceho pásmaAbeznrotej brúaky aapon z dvoch ploch od aaba oddálených lnou plochou; pričom prvé brúeieee plooha zvlara ao amerom pohybu obrobku v brúslacej medzera uholoci a druhé brúalaoa plocha uhol^k* ktorý aa rovné alebo je menSÍ ako unol<*i. RieSenie je nožné využit v ložiekovom a automobilovou priemysle.The proposed technical solution concerns a grinding wheel for a centerless grinder adapted to improve the geometric shape of the workpiece. The solution is based on the creation of a grinding zone for a centerless grinder consisting of two surfaces separated by a surface; the first grinding surface is the size of the workpiece movement in the grinding gap, and the second grinding surface is the angle which is equal to or less than 100°. The solution can be used in the bearing and automotive industries.

Vynález ea týká tvaru brúeneho páama brúsneho kotúča pra bazhroté brúaky upraveného pra zdokonaleni· geometrického tvaru obrobku·The invention ea relates to the shape of a grinding wheel of a grinding wheel for a bash-shaped grinding machine adapted to improve the geometrical shape of the workpiece.

Pri pradbažnom bazhrotom brúsení ·· orovnáva brúany kotúč podía šablony, na ktorej sú vytvořené postupná tri páaaa· Sú rozlišená podía velkosti a zmyslu uhle, ktorý zvlarajú ao amarom pohybu obrobku v brúslacaj madzara. Prvé ja náběhové a zároveň brúalaca péeao, druhé páaao vylakrovacla a trati· páamo výběhové. Najdoležitejiim páamoa pra zmenšenie chyby kruhovltoetl obrobku je brúalaca pásmo. V toato dochádza k odobaranlu najvačŠleho objsau materiálu z obrobku, pričom počiatočné vatupná ohýba kruhovltoatl obrobku ja regenerovaná pri bezhrotom prlebežnom bráeenl v závislosti na velkosti odoberaného přídavku ne jedno otočanla obrobku okolo avojaj oal v brúalacaj madzara bazhrotaj brúsky a od gooaotrického naatavanla obrobku v brůeiacej madzara. Súčaaný tvar brúanaho pásma tvořeného jednou plochou; zvlerajúoou ao amorom pohybu obrobku v brůeiacej medzere namanný uhol<*; umožňuje zmanu ohyby kruhovltoetl obrobku lan v aúvlaloatl a geometrickým nastavením výšky obrobku nad apojnleou oal podávaolaho a brúaiacaho kotúča a uhla podparnoj lišty bazhrotaj brúaky.In the basement grinding, grinding wheels grind the grinding wheel according to the template on which the successive three strips are formed. They are distinguished according to the size and purpose of the angle they are wrinkling and the amar movement of the workpiece in the grinding madzara. The first is the start and at the same time brúalaca péeao, the second Páao vylakrovacla and the line · Páamo the runway. The most important pameo for reducing the error of the circle of the workpiece is the grinding zone. In this case, the largest volume of material from the workpiece is removed, wherein the initial bending of the circular workpiece is regenerated at the pointless through-gate, depending on the size of the addition being taken, not one rotating workpiece around the avai in the grinding machine. The combined shape of a grinded-up zone formed by one surface; the angle of rotation of the workpiece at an angle <*; it allows the bending of the workpiece ropes to be varied in aúvlaloatl and by geometrically adjusting the workpiece height above the aperture of the feed and grinding wheel and the angle of the sub-bar of the bazhrotaj grinder.

Túto nevýhodu odstraňuj· tvar brúeneho kotúča v brúalacom pásma; na ktorom aú vytvořené aspoň dva plochy zvierajúca so amorom pohybu obrobku v brúanaj madzara rožne uhlyo^ a«_k; pričom ja menši akodc^·This disadvantage is overcome by the shape of the grinding wheel in the grinding zone; where AU formed of at least two grasping surfaces of Amor movement of the workpiece at different angles brúanaj Madzari N, _'a; where I am a minor ^ ^ ·

Tým aa v priebehu bazhrotáho prlobažrtého brúaanla maní úbor materiálu na jedno otočenie obrobku v brůeiacej madzara.Thus, and during the bashrotá prúžažrú brúaanla maní assortment of material for one turn of the workpiece in a grinding madzar.

Výhodou tohto natvarovaného brúaiacaho páaaa brúanaho kotúča ja zvýšenia preenoeti geometrického tvaru brúsených obrobkov už na jeden přechod v stroji.The advantage of this shaped grinding wheel and grinding wheel is that it increases the pre-geometry of the geometrical shape of the grinded workpieces for a single machine transition.

Přiklad vynálezu ja znázorněný na výkraaa obr. 1, ktorý představuje schématický pohlbd na usporiadania bazhrotaj brúaky a tvarom brúanaho páama brúanaho kotúča.An example of the invention is shown in FIG. 1, which is a schematic view of a beetle bazhrotaj arrangement and a shape of a grinded arm of a grinded wheel.

Na brúenom kotúčl JL aú ako brúena páama vytvořené dve plochy 2 a 3, ktoré aů od aa ba oddálené plochou 7, Plocha 2 ja pod uhlom a plocha J) pod uhlomo^ menším alebo rovným uhlu ^vo vztahu k amaru pohybu obrobku 4 v brúalacaj madzara tvorenej podévacim kotúčom 5 a podpěrnou lištou 6.In bruen kotúčl JL AU as bruen Paam provided with two faces 2 and 3, the AU from aa even spaced area 7, area 2 I an angle of a surface J) at an angle ^ less than or equal to the angle ^relative to Amaru movement of the workpiece 4 in brúalacaj Madžarov formed by a feed disc 5 and a support bar 6.

Riešenia podía predmetu vynálezu zvyšuje geometrická přesnost obrobku a ja ho možné využit v ložiakovom a automobllovoa priemysle.The solutions according to the invention increase the geometrical accuracy of the workpiece and can be used in the bedding and automobile industry.
