Description
L'invention a trait au domaine du polissage des lentilles ophtalmiques.The invention relates to the field of polishing ophthalmic lenses.
Elle concerne plus particulièrement un outil de polissage rotatif pour une telle lentille, cet outil étant prévu pour être monté sur la broche d'une machine à polir.It relates more particularly to a rotary polishing tool for such a lens, this tool being intended to be mounted on the spindle of a polishing machine.
La fabrication d'une lentille ophtalmique nécessite dans certains cas d'avoir recours à une opération de polissage au cours de laquelle un disque abrasif entraîné en rotation est maintenu contre la surface de la lentille et balaye cette surface, la lentille étant elle-même entraînée en rotation. Il est par conséquent nécessaire de prévoir des étapes au cours desquelles ce disque abrasif est remplacé par un disque neuf ou par un disque d'un grain différent.In some cases, the manufacture of an ophthalmic lens requires a polishing operation in which a rotating abrasive disc is held against the surface of the lens and sweeps the surface, the lens being itself driven. in rotation. It is therefore necessary to provide steps in which this abrasive disk is replaced by a new disc or a disc of a different grain.
On connaît des outils de polissage ou analogues adaptés à faciliter le remplacement d'un disque abrasif sans avoir à démonter l'outil de la broche de la machine à polir.Polishing tools or the like are known to facilitate the replacement of an abrasive disc without having to disassemble the tool from the spindle of the polishing machine.

Le but de l'invention est d'améliorer ce type d'outil de polissage qui comporte un plateau d'entraînement sur lequel peut être monté de manière amovible un disque abrasif.The object of the invention is to improve this type of polishing tool which comprises a drive plate on which can be mounted removably an abrasive disc.
A cet effet, l'invention vise un outil de polissage pour la finition d'une lentille ophtalmique, comportant :
- un plateau d'entraînement muni de moyens de montage sur la broche d'une machine à polir ;
- un patin de polissage amovible adapté à être entraîné en rotation par le plateau d'entraînement;
- des moyens de mise en position assurant une immobilisation radiale dudit patin par rapport audit plateau et permettant un coulissement axial du patin par rapport au plateau ;
- des moyens de retenue limitant le coulissement axial du patin par rapport au plateau à une plage de coulissement prédéterminée ;
- des moyens d'arrêt en rotation comportant au moins une dent adaptée à s'engager dans une encoche de forme correspondante, la dent et l'encoche étant disposées l'une sur le plateau et l'autre sur le patin.
- a drive plate provided with mounting means on the spindle of a polishing machine;
- a removable polishing pad adapted to be rotated by the drive plate;
- positioning means ensuring a radial immobilization of said pad relative to said plate and allowing axial sliding of the pad relative to the plate;
- retaining means limiting the axial sliding of the pad relative to the plate to a predetermined sliding range;
- rotation stop means comprising at least one tooth adapted to engage in a notch of corresponding shape, the tooth and the notch being arranged one on the plate and the other on the pad.
Un tel outil de polissage permet de découpler la mise en position du patin de polissage et son entraînement en rotation.Such a polishing tool makes it possible to decouple the setting in position of the polishing pad and its rotation drive.
La mise en place du patin de polissage est facilitée par le fait que l'intervention de l'utilisateur se borne à l'engagement du patin de polissage dans les moyens de retenue.The implementation of the polishing pad is facilitated by the fact that the intervention of the user is limited to the engagement of the polishing pad in the retaining means.
Il est en effet tiré parti de la force exercée par la broche de la machine à polir sur la lentille ophtalmique pour verrouiller en rotation le patin de polissage grâce aux moyens d'arrêt en rotation.It is in fact taken advantage of the force exerted by the spindle of the polishing machine on the ophthalmic lens to lock in rotation the polishing pad by means of stopping rotation.
Lors de l'engagement du patin de polissage dans les moyens de retenue, le patin de polissage coulisse librement le long de la plage de coulissement prédéterminée et ce n'est que lors de l'appui du patin de polissage sur la lentille ophtalmique et du démarrage de la rotation de la broche que la dent vient s'engager dans l'encoche, au moment où la dent et l'encoche se placent en vis-à-vis au terme d'une rotation relative du plateau d'entraînement par rapport au patin de polissage.When the polishing pad is engaged in the retaining means, the polishing pad slides freely along the predetermined sliding range and only when the polishing pad is supported on the ophthalmic lens and start of rotation of the spindle that the tooth engages in the notch, at the moment when the tooth and the notch are placed opposite each other at the end of a relative rotation of the drive plate relative to to the polishing pad.
L'utilisateur est dispensé d'avoir à orienter angulairement le patin par rapport au plateau puisque l'engagement de la dent dans l'encoche se fait automatiquement.The user is exempted from having to orient the pad angularly relative to the plate since the engagement of the tooth in the notch is done automatically.

L'outil de polissage 1 est employé de la manière suivante.The polishing tool 1 is used in the following manner.
Le plateau d'entraînement 4 et sa rotule 2 sont tout d'abord montés sur la broche de la machine à polir. Ces éléments sont prévus pour rester à poste sur la broche de la machine, seul le changement du patin de polissage 5 étant nécessaire pour remplacer un tampon de polissage 6 usé ou pour changer les caractéristiques du polissage.The
Le patin de polissage 5 est ensuite engagé dans le plateau d'entraînement 4 de manière que les pattes de fixation 13 se déforment pour que les bossages puissent pénétrer dans la rainure 9 en franchissant la collerette 10 sans tenir compte de la position relative des dents 11 et des encoches 15. L'intervention de l'utilisateur se limite à cet engagement.The
Le patin de polissage 5, bien que retenu dans la rainure 9 ne peut pas être à ce stade entraîné en rotation.The
L'outil de polissage 1 est alors mis en position contre la surface de la lentille ophtalmique à usiner et la rotation de la broche est activée simultanément ou postérieurement.The polishing tool 1 is then placed in position against the surface of the ophthalmic lens to be machined and the rotation of the spindle is activated simultaneously or subsequently.
Les dents 11 glissent alors sur le patin 5 jusqu'à leur engagement automatique dans les encoches 15.The
L'entraînement en rotation du patin 5 démarre et l'opération de polissage se poursuit de manière classique.The rotation drive of the
Des variantes de réalisation de cet outil peuvent être envisagées sans pour autant sortir du cadre de l'invention. Notamment, le patin de polissage 5 peut être utilisé directement, sans tampon de polissage, il comporte alors lui-même une surface abrasive. Par ailleurs, les dents 11 et les encoches 15 peuvent avoir une forme différente de celle décrite ici, il suffit que leur engagement mutuel soit permis. La position des dents 11 et des encoches 15 peut de plus être inversée de sorte que les dents 11 soient rattachées au patin 5 et que les encoches 15 soient pratiquées sur le plateau 4. Il en va de même pour la rainure 9 et les pattes 13.Alternative embodiments of this tool can be envisaged without departing from the scope of the invention. In particular, the
