  • Gripping On Spindles (AREA)

Abstract

The convertible control grip is utilizable mainly in self-gripping spring collets. It consists of a lever (1), equipped on its inner end with a screw (2) for a nut hole (3), in a sleeve (5). This solution is to shorten the time of the converting and to smooth the positioning of the lever (1). This purpose is achieved in the following way: the inner end of the lever (1) is equipped with a nut hole (6) for an arresting insert (7), whose pin (8), equipped with longitudinal guiding devices, is movably arranged in a hole (11) of the sleeves (5) protrusion (4) and the toothed end (12) of the arresting insert (7) is inserted into the indenture (13) of the body (14) of the control screw of the spring collets.<IMAGE>

Description

Vynález sa týká prestavitelnej ovládacej rukověte, použitelnéj najma pre samosvorné klieštinové upínače, pozostávajúcej z páky, opatrenej na jej vnútornom konci skrutkovým závitom pre maticový otvor v objímke.The invention relates to an adjustable operating handle, applicable in particular to self-locking collet chucks, comprising a lever provided at its inner end with a screw thread for a nut hole in the sleeve.

Ovládacia rukově£ na samosvornom klieštinovom upínaČi sa pri upínaní, alebo uvolňovaní nástrojového držiaka vychyluje v určitom uhlovom rozpátí. Toto uhlové rozpátie nemá stálu uhlovú polohu, ale sa v priebehu Času v dósledku opotrebovania súčastí upínača, alebo změny tolerancie upínaných obrobkov pootočí do inej polohy. U viacvretenových postupových obrábacích automatov sa však z priestorových dbvodov vyžaduje stabilná poloha tohto pracovného uhlového rozpětia. Aby sa zachovala táto požiadavka, musí by£ ovládacia rukovaí přestavitelné. Jej prestavenie sa podlá známého stavu techniky vykonává pootočením klieštiny, pričom vodiace pero sa uvedie do záběru s dalšou drážkou, umiestnenou na klištine, alebo sa páka rukovati preskrutkuje do dalšieho maticového otvoru v objímke. Takéto prestavovanie je zdlhavé a neumožňuje jemnú změnu polohy ovládacej rukověti .The operating handle 6 on the self-clamping collet is deflected in a certain angular span when clamping or releasing the tool holder. This angular span does not have a fixed angular position, but is rotated to another position over time due to wear of the fixture components or changes in tolerance of the workpieces to be clamped. However, in the case of multi-spindle transfer machine tools, a stable position of this working angular span is required for spatial reasons. In order to maintain this requirement, the control handle must be adjustable. According to the prior art, it is adjusted by turning the collet, the guide tongue being engaged with another groove located on the collet, or the handle lever is screwed into another nut hole in the sleeve. Such adjustment is lengthy and does not allow a slight change in the position of the operating handle.

Uvedené nevýhody odstraňuje přestavitelné ovládacia rukověí podlá vynálezu, ktorého podstata spočívá v tom, že vnútorný koniec páky je opatřený aj maticovým otvorom pre aretačnú vložku, ktorej driek, opatřený pozdlžnými vodiacimi prostriedkami, je posuvné uložený v otvore výstupku objímky a ozubený koniec aretaČnej vložky je vložený do ozubenia telesa ovládacej skrutky klieštinového upínača.The above-mentioned disadvantages are eliminated by the adjustable handle according to the invention, which is characterized in that the inner end of the lever is also provided with a nut hole for the locking insert, whose shank provided with longitudinal guiding means is slidably mounted in the opening of the sleeve protrusion and the toothed end of the locking insert into the toothing of the collet clamping screw control body.

Výhodou prestavitelnej ovládacej rukovati podlá vynálezu je, že jednoduchým spftsobom, bez demontáže, umožňuje pohodlné, rýchle a..jemné prestavenie páky do požadovanej polohy.An advantage of the adjustable handle according to the invention is that, in a simple manner, without disassembly, it enables a comfortable, quick and gentle adjustment of the lever to the desired position.

Příklad vyhotovenia prstavitelnej ovládacej rukovati podlá vynálezu je znázorněný na výkrese, na ktorom obr. 1 představuje nárysný rez a obr. 2 podorysný pohlad na rukově£ s čiastočným гегот v mieste aretaČnej vložky.An exemplary embodiment of an imaginable control handle according to the invention is shown in the drawing, in which FIG. 1 is a sectional view, and FIG. 2 shows a bottom view of the handle 8 with a partial grip at the position of the locking insert.

Přestavitelné ovládacia rukovaf pozostáva z páky 2' opatrenej na jej vnútornom konci skrutkovým závitom 2 pre maticový otvor 3 vo výstupku 4 objímky _5. Vnútorný koniec páky JL_, zaskrutkovaný do výstupku 4 objímky_5, je okrem svojeho skrutkového závitu 2 opatřený aj maticovým otvorom £ pre aretačnú vložku _7* ktorej válcový driek _8, opatřený pozdlžnými vodiacimi prostriedkami, například drážkou 9 a perom, alebo drážkou 9 a vodiacou skrutkou 10 s válcovým ukončením, je posuvné uložený vo valcovom otvore 23 výstupku 4 objímky 5. Ozubený koniec 12 aretaČnej vložky _7 je vložený do ozubenia 13, vytvořeného na telese 14 ovládacej skrutky kleštinového upínača.The adjustable control handle comprises a lever 2 'provided at its inner end with a screw thread 2 for a nut hole 3 in the projection 4 of the sleeve 5. The inner end of the lever 11 screwed into the projection 4 of the sleeve 5 is, in addition to its screw thread 2, also provided with a nut hole 8 for a locking insert 7, whose cylindrical shaft 8 is provided with longitudinal guiding means, for example groove 9 and tongue or groove 9 and guide screw 10 The toothed end 12 of the arresting insert 7 is inserted into the toothing 13 formed on the collet clamping screw control body 14.

Pohodlné a přesné prestavenie ovládacej rukovati do lubovolnej uhlovej polohy sa vykoná čiastočným vyskrutkovaním páky 1 z výstupku 4_, pričom sa zároveň zasúva smerom do páky 1 a j aretačná vložka 7. Ked sa jej ozubený koniec 12 vysunie z ozubenia 13, možno páku 1 pootočií o potřebný úhol okolo osi telesa 14 ovládacej skrutky. Po přestavení rukověti sa jej páka 1 opě£ zaskrutkuje, pričom ozubený koniec 12 aretaČnej vložky 7 sa uvedie znova do záběru s ozubením 13.Convenient and precise adjustment of the control handle to any angular position is accomplished by partially unscrewing the lever 1 from the protrusion 4 while simultaneously sliding the locking insert 7 into the lever 1. When its toothed end 12 is pulled out of the toothing 13, the lever 1 may be rotated an angle about the axis of the control screw body 14. After adjustment of the handle, its lever 1 is again screwed in, the toothed end 12 of the locking insert 7 being brought back into engagement with the toothing 13.

Přestavitelné ovládacia rukova£ v konkrétnom případe jej aplikácie značné ulehčuje manipuláciu s dvadsiatimiŠtyrmi upínaČmi viacvretenového rotorového automatu a podstatné znižuje neproduktívne stratové časy, pričom koncepciu prestavitelnej ovládacej rukověti podlá vynálezu možno výhodné využi£ okrem upínacej techniky aj v iných oboroch prestavovania či zais£ovania polohy komponentov alebo častí strojov.The adjustable handle in a particular application greatly facilitates the handling of the twenty-four clamps of a multi-spindle rotor automat and significantly reduces unproductive loss times, while the concept of the adjustable handle according to the invention can be advantageously used in other fields of positioning or securing or machine parts.
