Description

Vynález 3a týká zariadenia na vytvorenie rádiueov u obrobkov. Vynález je vhodný najma pra ložiskovú výrobu k výrobě vodiacich liSt pre bombíny ložiskových súčiastok.The invention 3a relates to a device for creating radii in workpieces. The invention is particularly suited for bearing production for the production of guide rails for bearing components.

Velký rádius dlhých obrobkov sa doposiaT bežne vytvářel iba na tenkých lištách po ich mechanickom rovinnom opracovaní ohýbáním. Ohýbáním líšt ee nedosiahla požadovaná přesnost velkých rádiusov. Uvedený spoeob výroby neumožňoval i vytváranie veřkých rádiusov na hrubších obrobkoch e opětovná opracovanie obrobku po jeho opotřebovaní. Známa je i výroba krátkých obrobkov a velkými rádiuemi pomocou univarzálnaj koplrovacej šablony, například podřa AO 227 724,' ktorá však nia Je vhodná pre výrobu dlhých obrobkov 3 velkými rádiuemi," lebo po celej dížke univerzálnej koplrovacej šablony pri vačšaj vzdialenosti upevňovacích hrotov aa daformačnou skrutkou v strada šablony nedosiahne požadovaná přesnost velkých rádiueov po celej dížka šablony. Taktiež je i známa velmi nákladná vytváranie velkých rádiueov pomocou čislicovo rledených brúsok.To date, the large radius of long workpieces has been produced only on thin strips after their mechanical planar bending. Bending the ee rails did not achieve the required accuracy of large radii. The above production also did not allow for the creation of large radii on thicker workpieces and the machining of the workpiece after its wear. It is also known to produce short workpieces and large radios using an univariate copying template, for example, according to AO 227 724, which is not suitable for the production of long workpieces with 3 large radios, "or along the entire length of the universal copying template at all spacing of the mounting tips and the information screw The strada template does not achieve the required accuracy of large radios across the entire template, as well as the costly creation of large radios using numerically polished sanders.

Horeuvedené riedoetetky odstráňuje zariadenie na vytvorenie rádiueov u obrobkov podlá vynálezu zložená z frémy e pozdížnym sup ort om,' priečným euportom 8 úchytkami, kopirovacaj šablony a brúsneho kotúča. Podstata riešenia je v tom; že na pozdížnom suporte je upevněná naklápacie podložka β umiestneným telesom priečneho suportu, v ktorom je upevněná posuvná část priečneho suportu; ktorej jeden koniec je opatřený tlačnou pružinou doeadajúcou na teleso priečného suportu a jej druhý koniec Je opatřený kopírovacím palcom spojeným 8 kopirovacou šablonou umiestnenou v držiaku, ktorý je otočné uložený pomocou čapu ne ramene frémy.The aforementioned apparatus removes the radio-forming apparatus of the workpieces according to the invention, consisting of a front and rear transverse support 8, a copying template and a grinding wheel. The essence of the solution is that; that a tilting pad β placed on the cross slide is placed on the cross slide in which the sliding part of the cross slide is fixed; one end of which is provided with a compression spring abutting the body of the transverse support and the other end thereof is provided with a copying thumb connected by a copying template disposed in a holder which is rotatably supported by a pin not of the fremen arm.

Zariadenie na vytvorenie velkých rádiueov dlhých obrobkov podlb vynálezu umožňuje bežnú sóriovú e malonákladnú výrobu veltoi přesných velkých rádiueov po celej dížke obrobku nielen na tenkých lištách, ale i na hrubých obrobkoch. Zariadenie umožňuje i brúsenie tvarových šablon velkých rádiueov dlhých obrobkov e rozličným priečným tvarom i z materiálu; ktorý nemožno opracovat ohýbáním.The device for generating large long-workpiece radios according to the invention allows for the conventional sulfur-free production of high-precision large radios across the entire workpiece not only on thin strips, but also on coarse workpieces. The device also allows grinding of shaped templates of large long workpiece radios with various transverse shapes and materials; which cannot be bent.

Na pripojenom výkrese je znázorněná zariadenie podlb vynálezu; kde na obrázku č. 1 je schematicky znázorněný princip zariadenia a na obrázku č. 2 je znázorněný přiklad provedenia univerzálnej koplrovacej šablony pre zariadenie podlb vynálezu.In the accompanying drawing, a device according to the invention is shown; wherein the principle of the device is schematically shown in Figure 1 and the example of an embodiment of a universal copier template for the device according to the invention is shown in Figure 2.

Zariadenie na vytvorenie rádiueov u obrobkov ee skládá z neklápecej podložky 5, ktorej požadovaný uhol naetavanla obrobku JL bude vytvářený otáčením podložky 5 okolo oei a jej poloha bude zafixovaná například pomocou skrutiek.The device for forming radii of workpieces ee consists of a non-sticking pad 5, the desired angle of which has been set by the workpiece 11 by rotation of the pad 5 about oe and its position being fixed, for example, by screws.

Ne naklápecej podložka 5 upevnenej na pozdížnom suporte 6 elektromagneticky alebo pomocou skrutiek; Je umiestnená teleso 3 priečneho suportu například 8 guřkovým vedením. Na posuvnej časti 2 priečneho suportu ja uchytený obrobok JL úchytkami 4. Oaden koniec posuvnej češti 2 priečneho suportu je opatřený tlačnou pružinou 11 doeadajúcou na těleso 2 priečneho suportu a Jej druýý koniec Je opatřený kopírovacím palcom 7, spojený β kopirovacou šablonou 8, umiestnenou v držiaku 9; ktorý ja otočná uložený pomocou čapu 10 na ramene 14 frémy 12.Not a tilting pad 5 fixed to the side slide 6 by electromagnetic or screws; A cross slide body 3 is placed, for example, by 8 ball guides. A workpiece 11 is attached to the sliding part 2 of the cross slide by the clips 4. The end of the slide 2 of the cross slide is provided with a compression spring 11 adjoining the cross body 2 and its other end is provided with a copy finger 7 connected by a β copying template 8 placed in the holder. 9; which is rotatably supported by a pin 10 on the arm 14 of the frame 12.

Obrobok JL aa upevni úchytkami 4 na posuvnú část 2 priečneho suportu. Naklápacou podložkou 5 sa nastaví požadovaný brúeený uhol obrobku JL voči tvarovanému brúsnemu kotúču 13. Tlačnou pružinou 11 sa dotlačí posuvnou častou 2 priečneho auportu kopírovací palec 7 na kopirovaciu šablonu 8, Pohybom pozdížnaho suportu 6 kopírovací palec 7 kopíruje tvar koplrovacej šablony 2 a súčasne sa brúsi povrch obrobku 1 za posuvu brúsneho kotúča 13.The work piece 11a and a fasten the tabs 4 to the sliding part 2 of the cross slide. The desired grinding angle of the workpiece 11 is adjusted by the tilt pad 5 to the shaped grinding wheel 13. The pressing spring 11 presses the copying finger 7 onto the copying template 8 by means of the sliding part 2 of the transverse auport. By moving the rear slide 6 the copying thumb 7 copies the shape of the copying template 2 and simultaneously grinds the surface of the workpiece 1 under the movement of the grinding wheel 13.
