Description

La présente invention a pour objet un dispositif d'assemblage du carter et du corps d'un brise-roche hydraulique (voir par exemple WO-A-01 85398 ).The present invention relates to a device for assembling the housing and the body of a hydraulic breaker (see for example WO-A-01 85398 ).

Les appareils de démolition du type brise-roche hydraulique, comprennent généralement un carter, à l'intérieur duquel est logé un corps comprenant le mécanisme hydraulique de frappe. A l'intérieur du corps est monté un outil, tel qu'un pic ou un burin, guidé et retenu par une douille de guidage, elle-même montée à l'intérieur du corps.The demolition apparatus of the hydraulic breaker type, generally comprise a housing, inside which is housed a body comprising the hydraulic striking mechanism. Inside the body is mounted a tool, such as a pick or chisel, guided and retained by a guide sleeve, itself mounted inside the body.

Lors du fonctionnement d'un brise-roche, un couple de rotation est transmis par le corps de l'appareil au carter, notamment lors de l'utilisation d'un outil dont l'extrémité active est orientée.When operating a breaker, a torque is transmitted by the body of the apparatus to the housing, especially when using a tool whose active end is oriented.

Il est donc nécessaire de limiter la rotation du corps à l'intérieur du carter.It is therefore necessary to limit the rotation of the body inside the housing.

Dans le cas de petits brise-roches hydrauliques, il est intéressant de réaliser des pièces, carter et corps de forme générale cylindrique, pour des raisons de simplicité de réalisation, de telles pièces pouvant être obtenues par tournage.In the case of small hydraulic breakers, it is interesting to make parts, housing and generally cylindrical body, for reasons of simplicity of realization, such parts can be obtained by turning.

Le corps doit donc être immobilisé en translation dans le carter par des butées mécaniques haute et basse, élastiques ou non, et sa rotation doit être limitée par un clavetage situé entre ces deux pièces.The body must be immobilized in translation in the housing by high and low mechanical stops, elastic or not, and its rotation must be limited by a key between these two parts.

Cet arrêt en rotation est durement sollicité lors du fonctionnement, par l'effet des vibrations et du couple transmis par l'outil au brise-roche, occasionnant parfois des usures prématurés.This rotating stop is harshly solicited during operation, by the effect of vibrations and the torque transmitted by the tool to the breaker, sometimes causing premature wear.

Cette limitation de rotation du corps par rapport au carter est également nécessaire dans le cas d'un carter et/ou d'un corps de section polygonale, de même forme ou non, montés avec jeu l'un dans l'autre.This limitation of rotation of the body relative to the housing is also necessary in the case of a casing and / or a polygonal section body, of the same shape or not, mounted with play one into the other.

Le but de l'invention est de fournir un dispositif d'assemblage du carter et du corps d'un brise-roche hydraulique dans lequel le blocage en rotation du corps et du carter puisse être réalisé de façon simple et avec une grande fiabilité.The object of the invention is to provide a device for assembling the housing and the body of a hydraulic breaker in which the rotational locking of the body and the housing can be achieved simply and with great reliability.

A cet effet, le dispositif qu'elle concerne, comprenant un carter, à l'intérieur duquel est logé un corps comprenant le mécanisme hydraulique de frappe, à l'intérieur duquel est montée une douille servant au guidage d'un outil, l'outil étant maintenu en rotation et limité en translation dans la douille de guidage par une clavette, et la douille de guidage étant maintenue en rotation et en translation dans le corps par une clavette, est caractérisé en ce que la douille de guidage comporte au moins une zone périphérique de forme non circulaire coopérant avec une zone de forme complémentaire ménagée dans la partie avant du carter, afin de limiter la rotation de la douille et donc du corps par rapport au carter.For this purpose, the device it concerns, comprising a housing, inside which is housed a body comprising the hydraulic striking mechanism, inside which is mounted a sleeve for guiding a tool, the tool being held in rotation and limited in translation in the guide sleeve by a key, and the guide sleeve being kept in rotation and in translation in the body by a key, is characterized in that the guide sleeve comprises at least one peripheral zone of non-circular shape cooperating with a complementary shaped zone formed in the front part of the casing, in order to limit the rotation of the the bushing and therefore the body relative to the housing.

Ainsi, dans le dispositif selon l'invention, la limitation en rotation du corps par rapport au carter, est réalisée par l'intermédiaire de la douille de guidage de l'outil, la douille étant bloquée en rotation sur le carter par l'intermédiaire d'au moins une zone périphérique de forme non circulaire, tandis que le corps est bloqué en rotation vis-à-vis de la douille par des moyens connus constitués par une clavette.Thus, in the device according to the invention, the limitation in rotation of the body relative to the housing, is achieved by means of the guide sleeve of the tool, the sleeve being locked in rotation on the housing via at least one peripheral zone of non-circular shape, while the body is locked in rotation vis-à-vis the sleeve by known means constituted by a key.

Suivant une forme d'exécution de ce dispositif, l'extrémité avant de la douille comporte au moins une facette destinée à venir en appui contre une facette ménagée dans la partie frontale du carter.According to one embodiment of this device, the front end of the sleeve comprises at least one facet intended to bear against a facet formed in the front portion of the housing.

Avantageusement, l'extrémité avant de la douille comporte une zone périphérique de section polygonale, et la partie frontale du carter comprend une ouverture de section polygonale complémentaire de la forme extérieure de la douille.Advantageously, the front end of the sleeve comprises a peripheral zone of polygonal section, and the front portion of the housing comprises an opening of polygonal section complementary to the outer shape of the sleeve.

Suivant une autre forme d'exécution de ce dispositif, l'extrémité avant de la douille et la partie frontale du carter comportent un jeu de cannelures - rainures longitudinales complémentaires.According to another embodiment of this device, the front end of the sleeve and the front portion of the housing comprise a set of grooves - complementary longitudinal grooves.

Selon une possibilité, les montages de l'outil dans la douille et de la douille dans le corps, sont réalisés à l'aide d'une clavette unique, orientée transversalement à l'axe du brise-roche et traversant des alésages, évidement et encoche ménagés respectivement dans le carter, dans le corps, dans la douille et dans l'outil.According to one possibility, the assemblies of the tool in the socket and the socket in the body, are made using a single key, oriented transversely to the axis of the breaker and through bores, recess and notch provided respectively in the housing, in the body, in the sleeve and in the tool.

Selon une autre possibilité, les montages de l'outil dans la douille et de la douille dans le corps, sont réalisés à l'aide de deux clavettes distinctes, orientées transversalement à l'axe du brise-roche, l'une des clavettes traversant des alésages et évidements ménagés dans le carter, dans le corps et dans la douille et l'autre clavette, traversant des alésages ménagés dans le carter et le corps et une encoche ménagée dans l'outil.According to another possibility, the assemblies of the tool in the socket and the socket in the body, are made using two separate keys, oriented transversely to the axis of the breaker, one of the keys running through bores and recesses formed in the housing, in the body and in the socket and the other key, through bores in the housing and the body and a notch in the tool.

Dans ce dernier cas, la douille de guidage peut être très courte, et n'être ménagée qu'à l'extrémité avant du corps et du carter.In the latter case, the guide sleeve can be very short, and be provided only at the front end of the body and the housing.

De toute façon, l'invention sera bien comprise, à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, plusieurs formes d'exécution de ce dispositif d'assemblage pour brise-roche hydraulique.Anyway, the invention will be better understood, with the aid of the description which follows, with reference to the attached schematic drawing showing, as non-limiting examples, several embodiments of this assembly device for hydraulic breaker.

Figure 1 est une vue en perspective éclatée des principaux composants d'un premier brise-roche. Figure 1 is an exploded perspective view of the main components of a first breaker.

Figure 2 en est une vue en perspective, les différents éléments étant assemblés. Figure 2 is a perspective view, the various elements being assembled.

Figure 3 en est une vue en coupe transversale selon la ligne III-III de figure 2. Figure 3 is a cross-sectional view along line III-III of figure 2 .

Figure 4 est une vue en perspective éclatée d'un second brise-roche, sans outil. Figure 4 is an exploded perspective view of a second breaker without tools.

Figure 5 est une vue en coupe longitudinale de la partie inférieure du brise-roche de figure 4, cette coupe étant réalisée suivant la ligne V-V de figure 4. Figure 5 is a longitudinal sectional view of the lower part of the figure 4 , this section being made along line VV of figure 4 .

Le brise-roche représenté aux figures 1 à 3 comprend un carter 2 de forme générale cylindrique, dont une extrémité est équipée d'une platine 3 de fixation sur le bras d'un engin ou similaire, et dont l'autre extrémité est équipée d'une partie frontale 4 comprenant une ouverture 5 destinée à permettre le passage d'un outil 6. A l'intérieur du carter 2 est destiné à venir se loger un corps 7 comprenant le mécanisme hydraulique de frappe, à l'intérieur duquel est montée une douille de guidage 8 servant au montage et au guidage de l'outil 6.The breaker represented at Figures 1 to 3 comprises a casing 2 of generally cylindrical shape, one end of which is equipped with a plate 3 for attachment to the arm of a machine or the like, and the other end of which is equipped with a front part 4 comprising an opening 5 intended to to allow the passage of a tool 6. Inside the casing 2 is intended to be housed a body 7 comprising the hydraulic striking mechanism, inside which is mounted a guide sleeve 8 for mounting and guide the tool 6.

En pratique, le carter 2 présente un alésage transversal 9 et le corps 7 présente un alésage 11 correspondant permettant l'engagement d'une clavette 10. Pour sa part, la douille de guidage 8 présente, dans sa paroi latérale, un évidement traversant 12 permettant le passage de cette même clavette 10, qui déborde à l'intérieur du volume délimité par la surface intérieure de la douille 8, comme montré à la figure 3, et pénètre dans une encoche 13 ménagée dans la partie arrière de l'outil 6. La clavette 10 sert donc à retenir la douille 8 vis-à-vis du corps 7 de même que l'outil 6 vis-à-vis du corps 7 et de la douille 8.In practice, the housing 2 has a transverse bore 9 and the body 7 has a corresponding bore 11 allowing the engagement of a key 10. For its part, the guide sleeve 8 has, in its side wall, a through recess 12 allowing the passage of the same key 10, which protrudes inside the volume defined by the inner surface of the sleeve 8, as shown in FIG. figure 3 and penetrates into a notch 13 formed in the rear part of the tool 6. The key 10 thus serves to retain the sleeve 8 vis-à-vis the body 7 as the tool 6 vis-à-vis the body 7 and socket 8.

Suivant la caractéristique essentielle de l'invention, l'extrémité de la douille 8 située du côté de la partie frontale du carter 2 présente un profil extérieur 14 à facettes, et plus précisément dans la forme d'exécution représentée au dessin, un profil polygonal constitué par une forme carrée à angles coupés. Pour sa part, la partie frontale 4 du carter 2 présente une ouverture 5 délimitée par un profil complémentaire du profil 14, afin que l'embout 14 soit parfaitement bloqué dans le profil 15.According to the essential characteristic of the invention, the end of the bushing 8 located on the side of the front portion of the housing 2 has an outer profile 14 faceted, and more specifically in the embodiment shown in the drawing, a polygonal profile consisting of a square shape with cut corners. For its part, the front portion 4 of the casing 2 presents a opening 5 delimited by a complementary profile of the profile 14, so that the tip 14 is perfectly blocked in the profile 15.

Ainsi, la douille de guidage 8 est bloquée en rotation vis-à-vis du carter 2, le corps 7 étant également limité en rotation vis-à-vis du carter 2 par l'intermédiaire de la douille 8 et de la clavette 10.Thus, the guide sleeve 8 is locked in rotation with respect to the housing 2, the body 7 being also limited in rotation with respect to the housing 2 via the bushing 8 and the key 10.

La figure 4 représente un autre brise-roche dans lequel les mêmes éléments sont désignés par les mêmes références que précédemment.The figure 4 represents another breaker in which the same elements are designated by the same references as before.

Dans ce cas, la douille 8 de guidage de l'outil 6 est plus courte que précédemment, de telle sorte que les fixations de la douille et de l'outil sur le corps sont réalisées séparément. Dans la forme d'exécution représentée, la clavette 10 est engagée dans l'encoche 13, et sert uniquement à la retenue de l'outil 6. Le carter 2 présente un autre alésage transversal 16, pour l'engagement d'une clavette 17, destinée à s'engager dans un évidement 18 de la douille de guidage 8, et à traverser un alésage 19 du corps.In this case, the guide bushing 8 of the tool 6 is shorter than previously, so that the fastenings of the sleeve and the tool on the body are made separately. In the embodiment shown, the key 10 is engaged in the notch 13, and serves only to retain the tool 6. The housing 2 has another transverse bore 16, for the engagement of a key 17 , intended to engage in a recess 18 of the guide sleeve 8, and to pass through a bore 19 of the body.

Dans ce cas encore et comme montré à la figure 5, le blocage en rotation du carter 2 et du corps 7 est réalisé par l'intermédiaire de la douille de guidage 8 par coopération de l'extrémité à facettes 14 de cette douille de guidage avec la partie frontale 4 du carter 2, qui présente une ouverture 5 délimitée par un profil 15 complémentaire de l'extrémité à facettes 14.In this case again and as shown in figure 5 , the rotational locking of the housing 2 and the body 7 is formed by means of the guide sleeve 8 by cooperation of the faceted end 14 of this guide sleeve with the front portion 4 of the housing 2, which has a opening 5 delimited by a profile 15 complementary to the faceted end 14.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un dispositif d'assemblage du carter et du corps d'un brise-roche de structure simple et d'un prix de revient économique.As can be seen from the foregoing, the invention brings a great improvement to the existing technique by providing a device for assembling the casing and the body of a breaker of simple structure and an economic cost price.
