Description
La présente invention concerne les organes d'un élément de bridage généralement utilisés pour maintenir sur la table de travail d'une machine outil les pièces qui doivent y être usinées.The present invention relates to the members of a clamping element generally used to hold on the work table of a machine tool the parts which must be machined there.
Ces éléments de bridage sont généralement constitués d'un boîtier qui est fixé sur une table de travail au moyen d'un organe d'assemblage coopérant avec un tasseau coulissant dans une rainure de la table de travail et dans lequel est disposée une pièce mobile en rotation autour d'un axe horizontal et munie d'un secteur denté coopérant avec une vis sans fin de commande, ladite pièce mobile comportant un bras formant levier dont l'extrémité vient en appui sur la pièce à usiner.These clamping elements generally consist of a housing which is fixed to a work table by means of an assembly member cooperating with a cleat sliding in a groove of the work table and in which a movable part is arranged. rotation about a horizontal axis and provided with a toothed sector cooperating with an endless control screw, said moving part comprising a lever arm whose end comes to bear on the workpiece.
Dans les éléments de bridage connus, le bras précité est solidaire de la pièce mobile, ce qui exclut toute possibilité de réglage de sa position par rapport au boîtier.In the known clamping elements, the aforementioned arm is integral with the movable part, which excludes any possibility of adjusting its position relative to the housing.
Par ailleurs, dans certaines utilisations, il peut s'avérer utile de réaliser un blocage ou un maintien vers le haut c'est-à-dire par ascension du bras formant levier.Furthermore, in certain uses, it may prove useful to block or hold it up, that is to say by raising the lever arm.
La présente invention à pour objet un élément de bridage du type décrit ci-dessus dans lequel on peut régler la position du bras par rapport au boîtier permettant de réaliser des blocages en agissant vers le haut ou vers le bas sur la pièce à bloquer.The present invention relates to a clamping element of the type described above in which one can adjust the position of the arm relative to the housing for performing blockages by acting up or down on the part to be blocked.
L'invention est notamment remarquable en ce que le bras formant levier est monté de manière amovible dans la pièce mobile permettant son déplacement en translation selon une direction sensiblement perpendiculaire à l'axe de rotation de la pièce mobile.The invention is particularly remarkable in that the lever arm is removably mounted in the moving part allowing it to move in translation in a direction substantially perpendicular to the axis of rotation of the moving part.
Cette disposition permet de régler la position relative du bras par rapport au boîtier afin de l'adapter aux différents cas d'utilisation.This arrangement makes it possible to adjust the relative position of the arm relative to the housing in order to adapt it to the different use cases.
Selon une autre caractéristique de l'invention, l'élément de bridage comporte un bras conformé de manière à pouvoir agir par soulèvement en venant s'appuyer sous une pièce à maintenir.According to another characteristic of the invention, the clamping element comprises an arm shaped so as to be able to act by lifting by coming to bear under a part to be held.
Le bras étant amovible, on peut ainsi disposer plusieurs bras pour un seul élément de bridage et on peut donc prévoir en particulier un bras agissant par soulèvement et non par action vers le bas.The arm being removable, it is thus possible to have several arms for a single clamping element and it is therefore possible in particular to provide an arm acting by lifting and not by action downwards.

L'élément d'organe de bridage représenté sur les figures 1 à 4 est constitué d'un boîtier 1 dans lequel est disposée une pièce 2 mobile en rotation autour d'un axe horizontal ; cette pièce rotative 2 comporte un secteur denté 21 qui coopère avec une vis sans fin de commande 4 disposée dans un logement aménagé à l'arrière du boîtier 1 et qui est fixée dans ce logement au moyen d'un écrou 5 et d'une rondelle 6. Cette vis de commande comporte une tête hexagonale 22 qui fait saillie du boîtier et qui permet sa rotation au moyen d'une clef.The clamping member element shown in Figures 1 to 4 consists of a housing 1 in which is disposed a
De manière connue, la pièce mobile 2 comporte un bras 3 formant levier dont l'extrémité libre est munie d'un patin d'appui 12.In a known manner, the moving
Conformément à la présente invention, le bras formant levier 3 est monté de manière amovible dans la pièce rotative 2 et peut coulisser dans cette dernière de manière à effectuer un mouvement de translation perpendiculairement à l'axe de rotation de la pièce rotative 2. Avantageusement, le bras 3 peut être bloqué dans la pièce rotative 2 en plusieurs positions relatives. Dans le mode de réalisation représenté, le bras 3 comporte dans sa face inférieure des évidements tel que celui représenté en 23 qui sont répartis sur toute sa longueur ; ces évidements coopèrent avec un dispositif de blocage 14 constitué par exemple par une bille montée sur un ressort.In accordance with the present invention, the
On peut le voir en particulier sur les figures 2 et 4, la pièce mobile 2 comporte un évidement central cylindrique 24 qui est coaxial avec l'axe de rotation de la pièce 2 et on dispose dans cet évidement central 24 deux flasques circulaires identiques 9 qui présentent en section transversale la forme d'un L et qui sont montés tête bêche de manière symétrique comme on peut le voir en particulier sur la figure 4 de manière à aménager entre eux un logement central pour le bras 3. les deux flasques sont assemblés l'un sur l'autre au moyen de deux vis 25 qui traversent chacune l'un des flasques et s'engagent dans un trou taraudé de l'autre flasque.We can see in particular in Figures 2 and 4, the
Comme on peut le voir sur les figure 6A, 6B, et 6C qui représentent un des flasques 9, ce dernier comporte un trou traversant lisse 26 perpendiculaire à l'une des branches du L et un trou taraudé 27 qui est aménagé axialement dans l'autre branche du L. Chaque flasque présente un épaulement 28 constituant une couronne qui vient en appui sur la face extérieure du boîtier 1. Comme on peut le voir sur les figures 6A à 6C, une rainure 29 est aménagées dans la couronne 28 ; cette rainure 29 coopère avec un ergot 17 aménagé dans la pièce 2 de manière à assurer un centrage de l'ensemble des deux flasques 9 lorsqu'ils sont assemblés.As can be seen in FIGS. 6A, 6B, and 6C which represent one of the
Les deux flasques, du fait de leur conception, favorisent, d'une part, une augmentation des surfaces de contact pour la rotation de la pièce mobile 2 et, d'autre part, permettent de rendre le boîtier monobloc et, par suite, d'augmenter la rigidité de ce dernier.The two flanges, by virtue of their design, favor, on the one hand, an increase in the contact surfaces for the rotation of the moving
Conformément à l'invention, le bras 3 est amovible et on peut utiliser d'autres bras tel que celui représenté sur la figure 5 qui est destiné à réalisé un appui vers le haut pour le blocage d'une pièce à usiner. Comme on peut le voir sur la figure 5, l'extrémité libre de ce bras 30 comporte une partie courbe 34 dont la concavité est dirigée vers le haut de manière que le patin d'appui (non représenté sur la figure 5) se trouve dirigé vers le haut.According to the invention, the
Les organes de bridage de type connu sont généralement fixés sur la table de travail d'une machine outil au moyen d'une vis 31 qui s'engage dans une encoche 32 du boîtier 1 et qui est vissée dans un tasseau coulissant dans une rainure de la table de travail. Dans les organes de bridage classiques, on utilise une seule vis 31 disposée à l'avant de l'organe c'est-à-dire du côté du bras 3. Conformément à l'invention, on prévoit une deuxième vis de fixation 33 disposée à l'arrière de l'organe de bridage, c'est-à-dire du côté opposé au bras 3. Cette deuxième vis s'engage également dans un tasseau coulissant dans une rainure de la table de travail et elle sert à maintenir l'organe de bridage sur la table dans le cas où on utilise un bras tel que celui de la figure 5 travaillant en appui vers le haut.The clamping members of known type are generally fixed to the work table of a machine tool by means of a
Comme on peut le voir sur les figures 7A à 7D, le patin d'appui 12 comprend une surface de contact 41 dont la longueur est sensiblement égale à deux fois la largeur ; cette surface de contact comporte en son centre une zone dégagée 42 qui permet d'asseoir au mieux la périphérie de la surface de contact 41.As can be seen in FIGS. 7A to 7D, the
La description ci-dessus n'a été fournie qu'à titre d'exemple illustratif et nullement limitatif et il est évident que l'on peut apporter des modifications ou variantes sans pour autant sortir du cadre de la présente invention.The above description has been provided by way of illustrative and in no way limitative example and it is obvious that modifications or variants can be made without departing from the scope of the present invention.
