Abstract
Přestavitelná úpinka umožňuje pohotové ustavenie úplňky pootočením stupňovitej podpěry (2), ktorá je uložená na vymeniteTnej zá^ . kladnéjpodpere (1). Upnutie obrobku (12) uskutočňuje sa skrutkovým sp'ojom, pričom hlava skrutky (6) je uložená v T drážke štola (9) a na jej driek je nasunutá základná podpěra (1), na ktorej je uložená stupňovitá podpěra (2), ktorá má vytvořené stupně (7) do kruhu a na dosadacích plochách stupňov (7) sú vytvořené zahíbenia (8), do ktorých zapadá gul’ka (5) osadená v prítlačnom ramene (4), pričom medzi přítlačným ramenom (4) a základnou podpěrou (1) je uložená tlačná pružina (3) a vzájomná poloha všetkých súčastí úpinky sa zaisti dotiahnutím matice (11).Adjustable clamp allows quick alignment the full turn by turning the stepped support (2), which is stored on a replaceable base. positive support (1). Clamping Workpiece (12) it is carried out with a screw connection, wherein the screw head (6) is housed in a T-slot the adit (9) and the base is slipped onto its shaft the support (1) on which it is mounted a stepped support (2) having formed step (7) into the circle and on the bearing surfaces degrees (7) are formed by hollows (8) into which the gul'ka (5) fits in the thrust arm (4), between the thrust arm (4) and base support (1) a compression spring (3) and a mutually reciprocating spring are supported the position of all parts of the clamp is secure by tightening the nut (11).
Description
Vynález rieši prestavitelná úpinku obrobkov.The invention solves the adjustable clamping of the workpieces.
Doposial’ sú známe přestavitelné úplňky, ktoré majú jednotlivé stupně výhotovené v radě za sebou. Nevýhodou týchto úpiniek je nutnosť ich posúvania pri nastavovaní, čím sa zváčšujú nároky na ustavovaciu plochu úpinky.Up to now, there are known adjustable full-length pads which have been made in series in series. The disadvantage of these plugs is the necessity of their sliding during adjustment, which increases the demands on the adjusting surface of the plug.
Uvedené nevýhody odstraňuje prestavitelná úpinka obrobkov podlá vynálezu pozostávajúca zo stupňovitej podpěry a na nej uloženého přítlačného ramena, ktoré sú navzájom přepojené skrutkovým spojom vybaveným tlačnou pružinou, usporiadaným pře pripojenie na stole obrábacieho stroja, ktorého podstata spočívá v tom, že stupňovitá podpěra je uložená na vymenitelnej základnej podpere, pričom stupňovitá podpěra má jednotlivé stupně usporiadané do kruhu a dosadacie plochy stupňov sú vybavené zahíbeniami pre aretačnú guli.čku, ktorá je osadená na konci přítlačného ramena.The above-mentioned disadvantages are overcome by the adjustable clamp of the workpieces according to the invention consisting of a stepped support and a pressure arm mounted thereon, which are interconnected by a screw connection equipped with a compression spring arranged over the attachment on the machine tool table. The stepped support has individual steps arranged in a circle and the step surfaces are provided with recesses for a detent ball which is mounted at the end of the pressure arm.
Výhody prestaviteínej úpinky podlá vynálezu sú v tom, že jednoduchým pootočením stupňovitej podpěry sa přestaví do takej polohy akú si vyžaduje momentálně obrábaná súčiastka, pričom jej prestavenie o váčšie hodnoty umožňuje jednoduchá výměna základnej podpěry príslušnej hrůbky.The advantages of the adjustable clamp according to the invention are that by simply rotating the stepped support, it is moved to the position required by the component being machined, and its adjustment by a larger value is made possible by a simple replacement of the base support of the respective depth.
Příklad prevedenia prestaviteínej úpinky je znázorněný na priloženom výkrese, kde znázorňuje obr. 1 rez A-A a obr. 2 pohlad na úpinku zhora.An exemplary embodiment of an adjustable clamp is shown in the accompanying drawing, wherein FIG. 1 shows section A-A and FIG. 2 is a top view.
V T drážke štola 2 obrábacieho stroja je skrutka £ tak, že jej driek vyčnieva zo štola 9 θ sú naň postupné nasunuté základná podpěra 2> na ktorej je uložená stupňovitá podpěra 2, ktorá má vytvořené stupně 7_ do kruhu a na dosadacích plochách stupňov 2 sú vytvořené zahíbenia 2j do ktorých zapadá gulka 2, osadená v prítlačnom ramene 2· Medzi přítlačným ramenom 2 a základnou podpěrou 2 íe vo vibraní 10 základnej podpěry 2 uložená tlačná pružina 3. Uvolněním matice 11, možno pootočit' stupňovitou podpěrou 2_ čím sa umožní nastavenie upínacej výšky přítlačného ramena 2· Vzájomná poloha přítlačného ramena 2 voči požadovanému stupňu 1_ stupňovitej podpěry 2 sa zaisti zapadnutím aretačnej gulky 2 do zahíbenia 2· P° vložení obrobku 12 pod přítlačné rameno 2 sa vzájomná poloha všetkých súčastí úpinky zaistí dotiahnutím matice 11.In the groove of the machine tool gallery 2, there is a screw 6 such that its shank protrudes from the gallery 9 with a stepped base support 2 on which a stepped support 2 is formed which has stepped steps 7 in a circle and is formed on the abutment surfaces of steps 2 eccentric relief 2j receiving the a bullet 2, mounted on the pressing arm 2 · 2 between the pressing arm and the base support 2 in a vibrant fe 10 base frame 2 mounted compression spring 3. the release of the nut 11 may be rotated "2_ stepped support to allow adjustment of the clamping height of the pressure arm 2 The relative position of the pressure arm 2 relative to the desired step 1 of the stepped support 2 is ensured by engaging the arresting ball 2 in the recess 2. After inserting the workpiece 12 under the pressure arm 2 , the relative position of all components is secured by tightening the nut 11.
