Description
Meule a patins abrasifs multiples.Grinding wheel with multiple abrasive pads.
On connaet déjà divers modes de réalisation de meules à patins abrasif s multiples qui sont généralement fiés, soit par brasage, par- collage, ou de façon mécanique, sur une monture formant corps de meule La fixation par brasage a l'inconvénient de détériorer la structure des liants et de l'abrasif ou d'empêcher l'utilisation de liants à composants à bas point de fusion et elle ne permet pas à l'utilisateur d'échanger aisément les patins, l'outil devant retourner chez le fabricant. La fixation par collage ne s 'applique qu'à certains liants de meules et n'est pas non plus commode pour l'utilisateur en cas d'échange ou remplacement des patins.Les fixations mécaniques connues de patins abrasifs sont généra- lement relativement complexes au niveau de la réalisation des patins, de l'ensemble d'assemblage de ceux-ci et de sa mise en oeuvre. We already know various embodiments of grinding wheels with multiple abrasive pads which are generally relied on, either by brazing, gluing, or mechanically, on a frame forming the body of a grinding wheel. The fixing by brazing has the disadvantage of deteriorating the structure of the binders and the abrasive or prevent the use of binders with components with a low melting point and it does not allow the user to easily exchange the pads, the tool having to return to the manufacturer. The fixing by gluing only applies to certain binders of grinding wheels and is not convenient for the user in the event of exchange or replacement of the pads. The known mechanical attachments of abrasive pads are generally relatively complex. at the level of the realization of the pads, the assembly assembly thereof and its implementation.
La présente invention a pour objet un mode de réalisation perfectionné de meule à montage mécanique de patins multiples, éliminant les inconvénients précités, et qui en cela est à la fois simple et de bonne tenue mécanique, en meme temps qugap- plicable avec tous patins constitués sous forme de barreaux venus de moulage avec une embase de fixation exempte d'abrasifs, pouvant etre du même liant que 1 ensemble du patin, que celui-ci soit métallique, résinoide, ou vitrifié ou en céramique. A cet effet, l'invention est essentiellement carac'tErisée en ce que la fixation des patins est prévue par l'intermédiaire d'organes de serrage en forme de coins coopérant avec au moins un flanc de l'embase de chaque patin et ayant une fixation par vis sur la monture. The present invention relates to an improved embodiment of a grinding wheel with mechanical mounting of multiple pads, eliminating the aforementioned drawbacks, and which in this is both simple and of good mechanical strength, at the same time qugap- plicable with all pads formed in the form of bars from molding with a fixing base free of abrasives, which may be of the same binder as 1 set of the pad, whether the latter is metallic, resinoid, or vitrified or ceramic. To this end, the invention is essentially characterized in that the fixing of the pads is provided by means of wedge-shaped clamping members cooperating with at least one side of the base of each pad and having a screw fixing on the frame.
Une telle réalisation permet aisément à l'utilisateur de remettre en état une meule par échange individuel ou partiel des patins. De tels patins peuvent aussi etre aisément montés de façon inclinée prédéterminée par rapport à l'axe de meule, ce qui permet d'obtenir une valeur de prise de passe correspondante dans le cas d'une meule boisseau et qui conduite dans le cas de meule périphérique, à'un recouvrement des parties abrasives. On conserve bien entendu l'avantage d'un système à patins multiples, ceux-ci pouvant équiper des montures de modèle différent (meule périphérique, boisseau, voire de forme) tout en constituant un stock uniforme de patins abrasifs pour l'utilisateur, pouvant êre diversifiés dans leur structure constitutive-suivant les matériaux à travailler. Such an embodiment easily allows the user to restore a grinding wheel by individual or partial exchange of the pads. Such pads can also be easily mounted in a predetermined inclined manner with respect to the grinding wheel axis, which makes it possible to obtain a corresponding tap-taking value in the case of a cup wheel and which drives in the case of a grinding wheel. peripheral, to a covering of the abrasive parts. Of course, the advantage of a system with multiple pads is retained, these being able to equip mounts of different model (peripheral grinding wheel, plug, or even shape) while constituting a uniform stock of abrasive pads for the user, which can be diversified in their constitutive structure - according to the materials to be worked.

La meule représentée aux fig. 1 à 3 comprend une monture ou corps de meule 1 en forme de disque à la périphérie duquel sont ici disposés, de façon inclinée par rapport à l'axe de meule, des patins 2 en forme de barreaux parallélépipédiques. The grinding wheel shown in fig. 1 to 3 comprises a mount or body of a grinding wheel 1 in the form of a disc at the periphery of which are here arranged, in an inclination with respect to the grinding wheel axis, pads 2 in the form of parallelepiped bars.
Ces patins-sont individuellement maintenus en place en même temps qu'espacés les-uns.des autres par l'intermédiaire d'organes de serrage en forme de coins 3, 4 engagés latéralement à la monture et à l'opposé l'un de l'autre de façon à serrer bilatéralement l'embase de chaque patin. Les coins 3 ou 4 situés d'un même côté sont individuellement formés à l'extrémité de languettes radiales 5 ou 6, s'étendant à partir d'un flasque circulaire commun 7 ou 8 et en-position normalement espacée axialement par rapport à la monture. Chaque flasque peut être positionné par l'intermédiaire de pions fixés latéralement sur la monture et sur lesquels s'engagent des orifices correspondants comme ici représenté pour l'un d'eux en 8a à la fig. 2.Chaque coin 3 ou 4 est individuellement serré contre l'embase du patin adjacent 1 par l'inter- médiaire d'une vis9, dont la tête prend appui dans un logement épaulé 10 de la languette et dont la tige filetée se visse dans un trou taraudé il de la monture 1. Les coins 3, 4 interposés entre patins adjacents prennent en outre en même temps appui l'un contre l'autre, de sorte que l'ensemble monté est d'une bonne tenue mécanique.These pads are individually held in place at the same time as spaced apart from one another by means of wedge-shaped clamping members 3, 4 engaged laterally to the frame and opposite one of the other so as to bilaterally tighten the base of each shoe. The corners 3 or 4 located on the same side are individually formed at the end of radial tabs 5 or 6, extending from a common circular flange 7 or 8 and in position normally spaced axially from the mount. Each flange can be positioned by means of pins fixed laterally on the frame and on which engage corresponding orifices as here shown for one of them in 8a in FIG. 2.Each corner 3 or 4 is individually tightened against the base of the adjacent shoe 1 by means of a screw9, the head of which is supported in a shouldered housing 10 of the tongue and the threaded rod of which is screwed into a threaded hole there in the mount 1. The corners 3, 4 interposed between adjacent pads also bear at the same time against each other, so that the assembled assembly is of good mechanical strength.
Les patins peuvent ainsi être éventuellement démontés individuellement et aisément par desserrage des languettes portant les coins 3 et 4 adja-cents aux patins considérés
Une autre réalisation de meule périphérique à patins inclinés est représentée aux fig. 4 à 5 selon laquelle les patins sont montés par paires dans des embrèvements 12 de la périphérie de la monture la, contre les bords en regard desquels ils sontappuyés par interposition d'un coin 13. Chaque coin l3 est monté serré entre les embases de ces patins par lgintermé- diaire d'une vis radiale 14, dont la tête prend appui dans un logement correspondant 15 du patin et dont la tige filetée se visse dans un trou radial taraudé 16 de la monture.The pads can thus be optionally disassembled individually and easily by loosening the tabs carrying the corners 3 and 4 adjacent to the pads considered
Another embodiment of a peripheral grinding wheel with inclined pads is shown in FIGS. 4 to 5 according to which the pads are mounted in pairs in recesses 12 of the periphery of the frame 1a, against the edges opposite which they are supported by the interposition of a wedge 13. Each wedge 13 is mounted clamped between the bases of these pads by the intermediary of a radial screw 14, the head of which is supported in a corresponding housing 15 of the pad and the threaded rod of which screws into a tapped radial hole 16 in the frame.
En variante, les fig. 6 et 7 illustrent une solution à plus grand angle de coincement obtenu entre chaque paire de patins 2 à l'aide de deux coins 17, 18, le premier 17 formant cale entre un patin et le coin adjacent 18-à fixation par vis 19, ce dernier coopérant à la fois avec la cale 17 et l'autre patin. As a variant, FIGS. 6 and 7 illustrate a solution with a larger wedging angle obtained between each pair of pads 2 using two corners 17, 18, the first 17 forming a wedge between a pad and the adjacent corner 18-with screw fixing 19, the latter cooperating with both the wedge 17 and the other pad.
On pourrait aussi prévoir de façon analogue un serrage de coin entre deux cales d'appui contre les barreaux de chaque paire. One could also provide similarly a corner clamping between two shims against the bars of each pair.
Les fig. 8 et 9 illustrent une réalisation d'une meule boisseau à l'aide de patins 2a montés mécaniquement selon l'invention, sur une monture 20 en forme de disque constituant corps de meule et présentant le long de son bord externe un embrèvement latéral 21 de contour polygonal, dont chacun des cotés 21a du polygone sert de zone d'appui à un patin. La monture présente en outre une gorge circulaire 22 adjacente et interne à l'embrèvement 21 ainsi qu'adaptée pour recevoir un coin de serrage 23 individuel par patin. Chaque coin présente une surface inclinée adaptée pour coopérer avec l'embase du patin et tendre à l'appuyer axialement et radialement contre les surfaces correspondantes dudit embrèvement 21, et cela à l'aide de deux vis de serrage 24, dont les têtes prennent appui dans un logement correspondant du coin de serrage et les tiges filetées dans des trous correspondants 25 de la monture. Figs. 8 and 9 illustrate an embodiment of a cup wheel using shoes 2a mechanically mounted according to the invention, on a disc-shaped mount 20 constituting body of the wheel and having along its outer edge a lateral recess 21 of polygonal outline, each of the sides 21a of the polygon serving as a support area for a skate. The mount further has a circular groove 22 adjacent and internal to the recess 21 as well as adapted to receive an individual clamping wedge 23 per pad. Each corner has an inclined surface adapted to cooperate with the base of the shoe and to tend to press it axially and radially against the corresponding surfaces of said recess 21, and this by means of two clamping screws 24, the heads of which bear. in a corresponding housing of the clamping wedge and the threaded rods in corresponding holes 25 of the frame.
Bien entendu de nombreuses autres variantes de réalisation peuvent être imaginées tout en restant dans le cadre de l'invention. Of course, many other alternative embodiments can be imagined while remaining within the scope of the invention.
