Abstract
Účelom vynálezu je přesné zalisovávanie najma_loží3k do otvorov súčiastok. Uvedeného účelu sa dosiahne nástrojům na zalisovávanie najma ložísk do otvorov súčiastok, ktorého podstatou je, že na trne je prostredníctvom pružných členov uložený dutý lisovací třň. Dutý lisovací trn má vytvorenú guíovú plochu v mieste dotyku s opiemou plochou nástroje.The purpose of the invention is the precise pressing of bearings into holes in components. The stated purpose is achieved by tools for pressing bearings into holes in components, the essence of which is that a hollow pressing mandrel is mounted on the mandrel by means of elastic members. The hollow pressing mandrel has a spherical surface formed at the point of contact with the supporting surface of the tool.
Description
Vynález sa týká nástroje na zalisovávanie najma ložíek do otvorov súčiastok.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for crimping particularly bearings into component openings.
Doteraz známe zariadenia majú pevné rovnoběžné lisovacie nástroje alebo odpružené celé lisovacie zariadenia, V iných prípadoch je pružné uložená súčiastka, do ktorej aa zalisováva ložisko alebo iná súčiastka. Nevýhodou týchto zariadení je, že uloženie lisovacieho nástroja j'e veími zložité, cena zariadenia a náklady na údržbu 3ú vysoké.The prior art devices have fixed parallel pressing tools or sprung whole pressing devices. In other cases, a resilient component is received in which aa is pressed into a bearing or other component. The disadvantage of these devices is that the placement of the pressing tool is very complicated, the cost of the device and the maintenance costs are high.
Uvedené nevýhody zmierňuje nástroj na zalisovávanie najma ložísk do otvorov súčiastok, ktorého podstatou je, že na trne je prostredníctvom pružných členov uložený dutý lisovací trn. Dutý lisovací trn má vytvorenú guíovú plochu v mieste dotyku s opiernou plochou nástroja.These disadvantages are alleviated by a tool for crimping especially bearings into component openings, which is based on the fact that a hollow press mandrel is mounted on the mandrel by means of resilient members. The hollow press mandrel has a spherical surface formed at the point of contact with the tool support surface.
Nástrojom na zalisovávanie najma ložísk do otvorov súčiastok sa docieli to,ože nástroj zachytává výchylky kolomosti a rovnobežnosti voči otvoru súčiastky do ktorého sa ložisko zalisováva. Výhodou je i to, že nástroj zvyšuje kvalitu zalisovávanie při mechanizovanéj a automatickéj montáži. Ďalšou výhodou je to, Že výroba nástroja je jednoduchá a lačná.The tool for pressing in particular the bearings into the holes of the parts achieves that the tool catches the deviations of perpendicularity and parallelism with the hole of the part into which the bearing is pressed. The advantage is also that the tool improves the quality of the pressing in mechanized and automatic assembly. Another advantage is that the production of the tool is simple and fast.
Nástroj na zalisovávanie najma ložísk do otvorov súčiastok je příkladné zobrazený na pripojenom výkrese, kde je nakreslený nástroj v podTžnom řeze s ložiskom a poisíovacím krúžkom připraveným na zalisovávanie a súčiastka, do otvoru ktorej sa zalisovanie vykoná.A tool for crimping particularly bearings into component holes is shown in the accompanying drawing, where the tool is shown in cross section with a bearing and a compression ring ready for crimping and the part into which the crimping hole is made.
Nástroj na zalisovávanie najma ložísk do otvorov súčiastok pozostáva z lisovacieho zariadenia 1, v ktorom je horizontálně uložený trn 2 s vytvořenou opiernou plochou 11.- Trň 2 je opatřený pružnými členmi 3, na ktorých je uložený dutý lisovací trň 4. Dutý lisovací třň 4 má vytvořená guíovú plochu 5 v mieste dotyku s opiernou plochou 11 nástroja. Druhý koniec dutého lisovacieho trna 4 je poistený voči posunutiu a stlahnutiu z trna 2 krúžkom 10.The tool for pressing in particular bearings into the holes of the parts consists of a pressing device 1 in which a mandrel 2 with a support surface 11 is formed horizontally. The mandrel 2 is provided with resilient members 3 on which the hollow pressing mandrel 4 is mounted. a spherical surface 5 at the point of contact with the tool support surface 11. The other end of the hollow press mandrel 4 is secured against displacement and compression from the mandrel 2 by the ring 10.
Na dutý lisovací trň 4 sa nasunie poistný krúžok 6 a ložisko 7. Súčiastka, do otvoru ktorej sa poistný krúžok 6 a ložisko 7 nalisováva, sa upne do upínacieho zariadenia /na obr. nezakreslené/. Po vykonaní přípravných práč sa dá povel k spusteniu lisovacieho zariadenia 1. Nástroj na zalisovávanie sa přiblíží k súčiastke 8 a pomocou zrazenej hrany 9 súčiastky 8 sa ložisko 7 navedie do správnéj polohy. Při dalšom přibližovaní nástroja na zlisovávanie sa ložisko 7 zalisováva do súčiastky a případné osové výchylky dutého lisovacieho trna 4 voči osi ložiska ]_ sa vyrovnávajú pomocov pružných členov 3. a guťovej plochy 5 dutého lisovacieho třňa 4. Po dosiahnutí predom nastavenej híbky zalisovania ložiska 2 a poisťovacieho krúžku 6 sa lisovacie zariadenie vráti do východiskovej polohy a je připravené k cíalšej operácii.The retaining ring 6 and the bearing 7 are pushed onto the hollow press mandrel 4. The part into which the retaining ring 6 and the bearing 7 is pressed is clamped into the clamping device (FIG. not shown /. After the pre-washing operations have been carried out, the pressing device 1 is started. The pressing tool approaches the component 8 and the bearing 7 is guided to the correct position by the chamfered edge 9 of the component 8. The instrument Bringing the zlisovávanie the bearing 7 zalisováva the components and the possible axial displacement of the hollow mandrel of the press to the axis of the bearing 4] _ are compensated by means of spring members 3 and 5 of the hollow Gut surface of the pressing mandrel 4. After reaching the pre-set cutting depth of pressing said two bearings and The locking device 6 returns the pressing device to the initial position and is ready for a further operation.
