Abstract
Navrhnuté technické riešenie sa týká podpernej lišty pre bezhroté brúsky, upravenej pre zdokonalenie geometrického tvaru obrobku. Podstatou riešenia ej vytvorenie plochy na podpernej lište zo súboru spojité sa meniacich dotyčníc k obrábanej ploché obrobku. Riešenie je možné využit pri výrobě ložísk.The proposed technical solution concerns a support bar for centerless grinders, modified to improve the geometric shape of the workpiece. The essence of the solution is to create a surface on the support bar from a set of continuously changing tangents to the machined flat workpiece. The solution can be used in the production of bearings.
Description
Vynález sa týká podpernej lišty pre bezhroté brusky, upravenej pre zdokonalenie geometrického tvaru obrobku.BACKGROUND OF THE INVENTION The present invention relates to a support bar for a centerless grinding machine adapted to improve the geometrical shape of a workpiece.
Pri priebežnom bezhrotom brúsení dochádza vplyvom vynútených alebo samobudených kmitov k úchylkám geometrického tvaru rotačných súčiastok. Ďalšou příčinou nepřesnosti ipri bezhrotom priebežnom brúsení je geometrické usporiadanie dotyčníc obrobku v bodoch dotykov brúsny kotúč obrobok, podávači kotúč obrobok, pdperná lišta obrobok.In the case of continuous centerless grinding, deviations of the geometric shape of the rotating parts occur due to forced or self-excited oscillations. Another cause of inaccuracy in the case of pointless continuous grinding is the geometrical arrangement of the workpiece tangents at the contact points of the grinding wheel workpiece, the workpiece feed wheel, the workpiece feeder bar.
Aby nedochádzalo k vzniku mnohohranu a zlepšila sa kruhovitost obrobku, před brúsením sa nastavuje bezhrotá brúska, pričom sa mění výška obrobku voči osiam brúsneho a podávacieho kotúča, alebo sa mění uhol opernej plochy podpernej lišty.In order to avoid the formation of a polygon and to improve the circularity of the workpiece, a centerless grinder is adjusted before grinding, changing the height of the workpiece relative to the axes of the grinding wheel and the grinding wheel, or changing the angle of the support surface.
Tento problém je riešený v čs. patentovom spise č. 188 726, kde je použitá podpěrná lišta, na ktorej sú aspoň dve opěrné plochy. Pri priebežnom bezhrotom brúsení sa obrobok opiera o plochu nabrúsenú pod uhlom λ. A po přestavení brúsky sa brúsi na ploché A‘. Nevýhodou je niekolkonásobné prebrúsovanie obrobku s přestavováním výšky obrobku. Táto úprava však ešte nevylučuje vznik mnohohranov.This problem is solved in MS. No. 188,726, wherein a support rail is used on which there are at least two support surfaces. In the case of continuous centerless grinding, the workpiece is supported on a surface sharpened at an angle λ. And after adjusting the grinder, it is ground to a flat A ‘. The disadvantage is the multiple grinding of the workpiece with the height adjustment of the workpiece. However, this does not preclude the emergence of polygons.
Uvedené nevýhody odstraňuje podpěrná lišta podta vynálezu, ktorej podstatou je, že na nej vytvořená plocha zo súboru spojité sa meniacich dotyčníc k povrchu brúsneho obrobku.The above-mentioned disadvantages are overcome by the support strip according to the invention, which is based on the fact that the surface formed thereon from the set of continuously changing tangents to the surface of the abrasive workpiece.
Výhodou podpernej lišty podlá vynálezu je zvýšenie přesnosti geometrického tvaru brúsených rotačných súčiastok už na jeden přechod v stroji.An advantage of the support rail according to the invention is to increase the accuracy of the geometrical shape of the ground rotary parts for a single transition in the machine.
Příklad vynálezu je znázorněný na výkrese, kde obr. 1 představuje schématický čiastočný bočný pohtad na podpernú lištu a obrobok a zároveň usporiadanie bezhrotej brúsky s podpěrnou lištou.An example of the invention is shown in the drawing, in which Fig. 1 is a schematic partial side view of the support bar and workpiece, and at the same time an arrangement of a centerless grinder with a support bar.
Medzi brúsnym kotúčom 1 a podávacím kotúčom 2 je podpěrná lišta 3, na ktorej je vytvořená tvarová plocha podl'a brúseného priemeru obrobku 4. Na podpernej lište 3 je plocha spojité sa meniacich dotyčníc ti až tx k brúsenej ploché obrobku.Between grinding wheel 1 and the feed disc 2, the supporting rail 3 on which is formed a shaped surface according to a ground diameter of the workpiece 4. At the support surface sheet 3 are continuous to those tangents varying x to t stock ground surface of the workpiece.
Riešenie podlá predmetu vynálezu zvyšuje geometrickú přesnost obrobku a jeho možné využiť pri výrobě ložísk.The solution according to the invention increases the geometrical accuracy of the workpiece and can be used in the production of bearings.
