Description

La présente invention se rapporte å un support mécanique pour le maintien d'un outillage électroportatif et son réglage précis en hauteur
le long d'une colonne.
The present invention relates to a mechanical support for holding a power tool and its precise height adjustment
along a column.

Le support mécanique objet de l'insention est plus part i cul èrement destiné au maintien d'une perceuse et en particulier d'une perceuse à monter dans un ensemble de perçage. The mechanical support object of the invention is more part i cul ère intended for maintaining a drill and in particular a drill to be mounted in a drilling assembly.

Dans les dispositifs connus Je ce yenre, le support de perçage est généralement constitué d'une table de travail, recevant une colonne montée perpendiculairement au plan de travail. cette colonne de section hexagonale ou circuiaire présente une crémaillère conformée dans la masse sur pratiquement toute sa longueur. In the known devices Je ce yenre, the drilling support generally consists of a work table, receiving a column mounted perpendicular to the work surface. this hexagonal or circular section column has a rack shaped in the mass over practically its entire length.

Sur cette colonne est fixé un berceau support de perceuse, lequel se déplace par action d'un levier en translation par rapport à la colonne. On this column is fixed a drill support cradle, which moves by the action of a lever in translation relative to the column.

Un dispositif d'arrêt et de retour constitué d'une bague et d'un ressort permet de limiter le dilattement ainsi que le retour du berceau dans sa position initiale libre.A stop and return device consisting of a ring and a spring makes it possible to limit the expansion as well as the return of the cradle to its initial free position.

Comme indiqué, des dispositifs ainsi conçus obligent la perceuse à rester toujours dans l'axe de la colonne. Egalement, la nécessité de conformer la crémaillère sur la presque totalité de la colonne entraîne des coûts de fabrication importants, d'autant plus élevés que la colonne est longue. As indicated, devices thus designed oblige the drill to always remain in the axis of the column. Also, the need to conform the rack over almost the entire column causes significant manufacturing costs, all the higher the longer the column.

L'invention a par conséquent pour but de remédier à ces inconvénients. The invention therefore aims to remedy these drawbacks.

A cet effet, elle se caractérise en ce que l'on adjoint à la colonne, un coulisseau permettant de rendre le berceau porte-outillage autonome > par rapport à ladite colonne en sue de fixer, de régler et d'orienter à poste l'outEilage électroportatif monté sur ce support.  To this end, it is characterized in that there is added to the column, a slide making it possible to make the tool holder cradle autonomous> relative to said column in order to fix, adjust and orient the post. power tooling mounted on this support.

Ainsi, le support selon l'insention comporte un coulisseau de faible longueur, une ou plusieurs brides bloquantes à ses extrémités ainsi qu'un mecanisme d'orientation et de fixation du berceau, support qui maintient l'outillage électro-portatif. Thus, the support according to the invention comprises a short slide, one or more blocking flanges at its ends as well as a mechanism for orienting and fixing the cradle, support which maintains the power tool.

L'invention permet donc d'obtenir, d'une part, un ensemble fiable et ' robuste de réglage et de fixation du berceau pour la mise en place précise d'une perceuse à poste. !'autre part, le support selon l'invention évite la fabrication d'une crémaillère de grande longueur taillée dans la masse de la colonne. The invention therefore makes it possible, on the one hand, to obtain a reliable and robust assembly for adjusting and fixing the cradle for the precise positioning of a station drill. on the other hand, the support according to the invention avoids the manufacture of a very long rack cut in the mass of the column.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui suit, effectuée à titre d'exemple non limitatif sur un mode d'exécution en référant aux dessins accompagnants dans lesquels
- la figure 1 est une vue de profil du
support selon l'invention monté sur
un ensemble d'usinage à plateau et
à colonne.
Other characteristics and advantages of the invention will appear during the description which follows, given by way of nonlimiting example in one embodiment with reference to the accompanying drawings in which
- Figure 1 is a side view of the
support according to the invention mounted on
a set of plate machining and
to column.

- la figure 2 est une vue en coupe transser-
sale de la figure 1.
- Figure 2 is a cross-sectional view
dirty in figure 1.

Le support de perçage présenté dans son ensemble en figure 1 est constitué d'une table de travail 1, d'une colonne support 2 ainsi que d'un berceau 3 assurant le maintien de la perceuse proprement dite 4. The drilling support presented as a whole in FIG. 1 consists of a work table 1, a support column 2 as well as a cradle 3 ensuring the maintenance of the actual drill 4.

Un coulisseau 5 de forme extérieure par exemple hexagonale est monté coulissant sur la colonne 2 à la manière d'une douille. A slide 5 of external shape, for example hexagonal, is slidably mounted on the column 2 in the manner of a socket.

Bien entendu, la conformation intérieure du coulisseau 5 est adaptée à la forme de section > de la colonne par exemple circulaire ou calindrique si la colonne est tubulaire.  Of course, the internal conformation of the slide 5 is adapted to the shape of the section> of the column, for example circular or cylindrical if the column is tubular.

Le coulisseau 5 comporte à ses extrémités deux brides 6 et 7 servant de butées d'extrémité au berceau 3. The slide 5 has at its ends two flanges 6 and 7 serving as end stops for the cradle 3.

La distance entre ces deux brides donne
l'amplitude de mouvement du berceau par raport à chaque position du coulisseau 5 le long de la colonne 2.
The distance between these two flanges gives
the range of motion of the cradle relative to each position of the slide 5 along the column 2.

Le coulisseau 5 comporte une crémaillère 8 de faible longueur dont les dents engrennent sur le pignon .9 actionné par un levier de manoeuvre 10. The slide 5 comprises a short rack 8 whose teeth mesh with the pinion .9 actuated by an operating lever 10.

Selon un autre mode de réalisation de l'invention, la crémaillère 8 peut être réalisée brute de fonderie directement à la longueur correspondant à la translation du berceau 3. According to another embodiment of the invention, the rack 8 can be made rough casting directly to the length corresponding to the translation of the cradle 3.

Un ressort de rappel 11 monté entre le coulisseau 5 et le berceau 3, monté par exemple autour du coulisseau 5 permet de réaliser le retour automatique dudit berceau à sa position intiale. A return spring 11 mounted between the slide 5 and the cradle 3, mounted for example around the slide 5 allows the automatic return of said cradle to its initial position.

Selon un autre mode de réalisation, le berceau 3 peut comporter des lardons 12 de guidage dont la face interne épouse exactement la conformation extérieure du coulisseau. According to another embodiment, the cradle 3 may include guide strips 12 whose internal face exactly matches the external conformation of the slide.

On expliquera ci-après les différentes phases de fonctionnement du support selon l'invention. The various phases of operation of the support according to the invention will be explained below.

La perceuse étant montée sur le berceau 3 de l'ensemble de perçage; I'opérateur par desserage des butées bloquantes, règle la hauteur de l'outil en fonction de l'épaisseur de lapièce à travailler. The drill being mounted on the cradle 3 of the drilling assembly; The operator by loosening the locking stops, adjusts the height of the tool according to the thickness of the workpiece.

Les butées bloquantes 6 et 7 étant resserrées, par action sur le levier 10, le pignon engrenant sur le crémaillère 8 fera effectuer au berceau le mouvement de translation désiré. Si on relache la pression sur le levier, le ressort 11 fait revenir ledit berceau dans sa position initiale.The locking stops 6 and 7 being tightened, by action on the lever 10, the pinion meshing on the rack 8 will cause the cradle to carry out the desired translational movement. If the pressure on the lever is released, the spring 11 returns said cradle to its initial position.

Le support, objet de la présente invention, peut être utilisé dans tous les cas de perçage ou de fraisage nécessitant un usinage de précision. The support, object of the present invention, can be used in all cases of drilling or milling requiring precision machining.

II peut être utilisé en atelier, dans les domaines du bricolage, de l'électronique ou de la mécanique. It can be used in the workshop, in the DIY, electronics or mechanics fields.

Diverses modifications évidentes, variantes directes, substitution par des matériaux, matières ou moyens équivalents et autres modifications sans apport inventif entrent dans le cadre de la présente invention.  Various obvious modifications, direct variants, substitution with materials, materials or equivalent means and other modifications without inventive contribution are within the scope of the present invention.
