Abstract

The shaft carries a component from whose boss four integrally formed tongues project axially. The clamp ring is formed with a central hole having four spiral cam surfaces so that when turned hard in clockwise direction it presses the tongues into frictional contact with the shaft. The clamping ring and the component it fixed can be readily made of injection moulded plastic and so is cheap, simple to fit and it occupies little space. The fixture may be used on light precision parts.

Die Erfindung betrifft- eine Klemmvorrichtung für zylindrische Teile. . . ,The invention relates to a clamping device for cylindrical Parts. . . ,

Zum schnellen, schlagfreien Einspannen von zylindrischen Teilen finden Spannzangen Verwendung, die aus einer geschlitzten Hülse bestehen. Die Spannzange wird mittels einer Überwurfmutter in ein entsprechend geformtes konisches Gegenstück gepreßt und dabei radial zusammengedrückt. Elemmvorrichtungen dieser Art sind fertigungstechnisch schwierig herstellbar und somit teuer. Außerdem besitzen derartige . Spannzangen eine große Baulänge, die keine vielseitige Anwendbarkeit zuläßt und deren Einsatz hauptsächlich auf Werkzeugmaschinen beschränkt.For fast, impact-free clamping of cylindrical parts, collets are used that consist of a slotted Sleeve exist. The collet is secured by means of a union nut pressed into a correspondingly shaped conical counterpart and thereby compressed radially. Clamping devices of this type are difficult to manufacture manufacturable and therefore expensive. Also have such. Collets have a large overall length, which is not versatile and their use is mainly limited to machine tools.

Der Erfindung liegt die Aufgabe zugrunde, eine Klemmvorrichtung für zylindrische Teile zu schaffen, die fertigungstechnisch besonders leicht und billig herstellbar sein soll und die überdies eine flache, nur wenig Raum beanspruchende Bau— form aufweisen soll. Dabei soll sie eine zuverlässige Klemmung gewährleisten und gleichmäßige, zentrisch wirkende Spannkräfte erzeugen. Sie soll ferner leicht anzubringen, einfach zu betätigen und vielseitig anwendbar sein.The invention is based on the object of creating a clamping device for cylindrical parts which, in terms of manufacturing technology should be particularly easy and cheap to manufacture and which, moreover, has a flat structure that takes up little space should have shape. It should be a reliable one Ensure clamping and uniform, centrally acting Generate tension forces. It should also be easy to install, simple to operate and be versatile.

Die Erfindung löst die gestellte Aufgabe bei einer Klemmvorrichtung für zylindrische Teile dadurch, daß ein zylindrischer Teil von einer nach Art einer Spannzange geschlitzten Hülse umschlossen ist, die mittels eines Klemmringes reibungssäilüssig an den zylindrischen Teil gepreßt wird, und zwar durch Drehen des Klemmringes, der tangential am- Umfang verlaufende, auf die geschlitzte Hülse einwirkende Kurvenbahnen , aufweist. ·The invention solves the problem posed in a clamping device for cylindrical parts in that a cylindrical Part of a sleeve slotted like a collet is enclosed, the friction-säilüssig by means of a clamping ring is pressed against the cylindrical part, namely by turning the clamping ring, the cam tracks running tangentially on the circumference and acting on the slotted sleeve, having. ·

Die Vorteile der Erfindung kommen besonders zum Tragen, wenn Teile der Klemmeinrichtung aus verschleißfestem Kunststoff gefertigt, sind. Der konstruktive Aufbau dieser Klemmvorrichtung ermöglicht nämlich eine besonders leichte Ausform— barkeit aller Kunststoffteile, so daß eine billige Herstellung als Massenerzeugnis möglich ist. Trotzdem gewährleistet diese Klemmvorrichtung auch bei hohen Drehzahlen eine zuverlässige Klemmung, ohne daß die Gefahr besteht, daß die Klemmwirkung z.B. infolge von Vibrationen beeinträchtigt wird. Diese gute Klemmwirkung wird nach einem weiteren Merkmal der Erfindung auch durch eine elastische Verformung des Klemmringes erreicht, wobei der als Spannkurve ausgebildete Klemmring gleichmäßige Radialkräfte erzeugt. Es treten demnach beim Klemmen keine Zwangskräfte auf, die das zu spannende Teil deformieren könnten. Aus diesem Grunde eignet sich die Klemmvorrichtung nach der Erfindung besonders zum Zentrieren und Klemmen von Präzisionsteilen, wie z.B. Teilkreisen oder dergl. Die flache Bauweise, leichte Montage und einfache Betätigung des Klemmringes gestattet deren Anwendung auch in kleinsten Baueinheiten, wie z.B. in lichtelektrischen Dreh— gebern.The advantages of the invention are particularly evident when parts of the clamping device are made of wear-resistant plastic are manufactured. The structural design of this clamping device enables a particularly easy shaping availability of all plastic parts, so that inexpensive mass production is possible. Nevertheless, this guarantees Clamping device a reliable clamping even at high speeds without the risk of the clamping effect e.g. is impaired as a result of vibrations. This good one According to a further feature of the invention, the clamping effect is also achieved by elastic deformation of the clamping ring, whereby the clamping ring designed as a clamping curve generates uniform radial forces. It occurs accordingly at Do not create any constraining forces that could deform the part to be clamped. The clamping device is suitable for this reason according to the invention especially for centering and clamping precision parts, such as pitch circles or The like. The flat design, easy assembly and simple operation of the clamping ring allows its use even in the smallest structural units, such as in photoelectric rotary donors.
