Abstract

Predmetom riešenia je upínacie zariadenie umožňujúce upnutie najmá váčších súčiastok s otvormi so závitom pre potřebu technologickej manipulácie (otáčanie, piosúvaniej pri ich opravách, napr. v stavebném strojárenstve pri opravách dozerov. Upínac súčiastok s otvormi so závitom je vyznačený tým, že pozostáva z objímky upevnenej skrutkami k upínacej doske a zo skrutky, na ktorú je naskrutkovaná matica, pod ktorou je pružina, pričom objímka je uzavretá vekom s nalisovaným puzdrom a poistnou maticou.The subject of the solution is a clamping device enabling clamping of at least larger components with threaded holes for the purpose of technological manipulation (rotation, sliding during their repairs, e.g. in construction machinery during repairs of dozers. The clamping device for components with threaded holes is characterized in that it consists of a sleeve fixed with screws to the clamping plate and a screw onto which a nut is screwed, under which there is a spring, while the sleeve is closed with a lid with a pressed-on sleeve and a lock nut.

Description

Predmetom, vynálezu je upínacie zariadenie umožňujúce upnutie, najmä väčších súčiastok s otvormi so závitom pre potrebu technologickej manipulácie (otáčanie, posúvanie] pri ich opravách, napr. v stavebnom strojárenstve pri opravách dozérov.It is an object of the invention to provide a clamping device for clamping, in particular of larger threaded openings, for the need for technological manipulation (turning, shifting) in their repair, e.g. in construction machinery for repairing dozers.

Doteraz sa na uvedený účel používa upínanie pomocou skrutiek, čo je nevýhodné z hľadiska ich trvanlivosti, univerzálnosti.Up to now, screw clamping is used, which is disadvantageous in terms of durability, versatility.

Podstatou vynálezu je, že pozostáva z objímky upevnenej skrutkami k upínacej doske a zo skrutky, na ktorú je zaskrutkovaná matica, pod ktorou je pružina, pričom objímka je uzavretá vekom s nalisovaným puzdrom a poistnou maticou.SUMMARY OF THE INVENTION It is an object of the present invention to provide a sleeve fastened with screws to a clamping plate and a screw to which a nut is screwed, under which a spring is provided, the sleeve being closed by a cover with a press-fit sleeve and a lock nut.

Vyšší účinok vynálezu spočíva vo zvýšení trvanlivosti a univerzálnosti uipínacieho mechanizmu. • Účinok je schematicky znázornený v priečnom reze na pripojenom obrázku.The higher effect of the invention is to increase the durability and versatility of the clamping mechanism. The effect is schematically shown in cross-section on the attached figure.

Upínač pozostáva z objímky 1, ktorá-je u-ipevnená skrutkami 12 k upínacej doske 10 a zo skrutky 2, na ktorú je naskrutkovaná matica 8, pod ktorou je pružina 9, objímka 1 je uzavretá vekom 6 s nalisovaným puzdrom 4 a poistnou maticou 7.The clamp consists of a sleeve 1 which is fixed by screws 12 to a clamping plate 10 and a screw 2 to which a nut 8 is screwed under which a spring 9 is provided, the sleeve 1 being closed by a lid 6 with a pressed sleeve 4 and a lock nut 7 .

Funkcia upínača je nasledovná:The fixture function is as follows:

Po nasadení kľúča alebo mechanického skrutkovača na horný štvorhran skrutky 2 po jej čiastočnom zatlačení vo smere osi, sa činný koniec skrutky 2 opatrený kužeľom, pre lepší nábeh do príslušného závitu otvoru v súčiastke 11 zachytí v závitovej dutine súčiastky 11, ku ktorej sa upínač pripevňuje. Puzdro 4 slúži ako vedenie pre skrutku 2 a po jej dotiahnutí sa matica 8 oprie o puzdro 5 potrebné na zastredenie objímky 1 a tým i celého upínača.After the key or the mechanical screwdriver has been mounted on the upper square of the screw 2 after it has been partially pushed in the axis direction, the active end of the screw 2 provided with a cone, for better penetration into the respective thread of the hole in the component 11, is caught in the threaded cavity of the component 11 to which the fixture is attached. The sleeve 4 serves as a guide for the screw 2 and, after tightening it, the nut 8 rests on the sleeve 5 necessary to accommodate the sleeve 1 and thus the entire clamp.

Puzdro 5 slúži zároveň ako doraz. Pri u-voľnení skrutky 2 pružina 9 vysunie skrutku 2 do pôvodnej polohy, tým sa činný koniec skrutky 2 vtiahne do vypínača, čím sa zamedzí jeho poškodeniu pri manipulácii.The housing 5 also serves as a stop. When loosening screw 2, spring 9 extends screw 2 to its original position, thereby pulling the active end of screw 2 into the switch, thereby preventing its damage during handling.

Zariadenie je pri vhodnom dimenzovaní využiteľné tiež všeobecne v opravárenstve pri opravách rôznych, najmä ťažkých mechanizmov.The device is also suitable in general for repairing various, especially heavy, machinery in a suitable dimensioning.
