Description
Cylindre de travail oscillant pour fluides pneumatiques et hydrauliques sous pression. La présente invention se rapporte à un cylindre de travail oscillant, destiné à des fluides pneumatiques ou hydrauliques sous pression, et muni d'un cou vercle et d'un fond fixés par des boulons. Oscillating work cylinder for pneumatic and hydraulic fluids under pressure. The present invention relates to an oscillating working cylinder for pneumatic or hydraulic fluids under pressure and provided with a neck and a bottom fixed by bolts.
On connaît des cylindres de travail de ce genre sur l'enveloppe desquels sont agencés des tourillons dirigés perpendiculairement à l'axe du cylindre et destinés à être montés dans des paliers. Ces touril lons ne permettent un mouvement d'oscillation qu'autour d'un axe fixe, car ils sont solidaires du cylindre. Work rolls of this type are known on the envelope of which are arranged journals directed perpendicularly to the axis of the cylinder and intended to be mounted in bearings. These touril lons allow an oscillation movement only around a fixed axis, because they are integral with the cylinder.
Étant donné la multiplicité des exigences quant à la position des tourillons et quant aux difficultés de placer ces tourillons à angles droits, notamment sur des cylindres longs et à parois minces, il s'est avéré nécessaire de prévoir une bague de support déplaçable de long du cylindre et capable d'être reliée à celui-ci en un endroit quelconque. Du fait de la relativement faible épaisseur de la paroi du cylindre, il n'est cependant pas possible de serrer par des boulons une telle bague directement sur ce cylindre, car on déformerait celui-ci dont le fonc tionnement serait entravé sinon rendu impossible. Given the multiplicity of requirements regarding the position of the journals and the difficulties of placing these journals at right angles, especially on long cylinders and thin walls, it has proved necessary to provide a support ring movable along the length cylinder and able to be connected to it in any place. Due to the relatively small thickness of the wall of the cylinder, it is however not possible to tighten by bolts such a ring directly on the cylinder, because it would deform it whose operation would be hindered if not made impossible.
La présente invention a pour objet un cylindre de travail oscillant évitant les inconvénients men tionnés et remarquable, notamment, par une bague de support munie de tourillons et agencée pour être montée avec jeu sur le cylindre, entre le couvercle et le fond fixés sur celui-ci par des boulons, ladite bague étant prévue pour être reliée rigidement aux- dits boulons. La bague de support comporte des ouvertures qui sont destinées à recevoir les boulons et dans lesquelles débouchent des fentes, des élé ments de serrage réalisés de cette manière, et pouvant être comprimés à l'aide de vis, constituant une liai son rigide de la bague de support et desdits boulons. The present invention relates to an oscillating working cylinder avoiding the disadvantages mentioned and remarkable, in particular, by a support ring provided with pins and arranged to be mounted with play on the cylinder, between the cover and the bottom fixed on it. ci by bolts, said ring being provided to be rigidly connected to said bolts. The support ring has apertures for receiving the bolts and into which slots, clamping elements made in this way, and which can be compressed by screws, constituting a rigid connection of the ring, open out. support and said bolts.
D'autres objets et avantages de l'invention seront mieux compris à l'aide de la description détaillée qui va suivre et du dessin annexé sur lequel La figure 1 est une vue en élévation latérale d'un cylindre conforme à l'invention muni d'une bague de support. Other objects and advantages of the invention will be better understood with the aid of the detailed description which follows and the attached drawing in which FIG. 1 is a side elevational view of a cylinder according to the invention provided with a support ring.
La figure 2 est une vue en plan de la bague de support, et La figure 3 est une vue en élévation latérale de ladite bague. Fig. 2 is a plan view of the support ring, and Fig. 3 is a side elevational view of said ring.
La figure 1 représente un cylindre 1 muni d'un fond 2 et d'un couvercle 3 qui sont assemblés dans l'exemple représenté, par quatre boulons 4a, 4b, 4c et 4d. Le couvercle présente de manière connue un prolongement 3a en forme de col comportant une ouverture de passage pour la tige de piston 5. Entre le fond 2 et le couvercle 3 est montée sur le cylindre une bague de support 6 dont le diamètre interne est légèrement supérieur au diamètre du cylindre 1. Cette bague comporte quatre ouvertures <I>7a, 7b,</I> 7c et<I>7d</I> dans lesquelles débouchent latérale ment des fentes 8a, <I>8b, 8c,</I> et 8d. De cette manière sont réalisées des pièces de serrage 9a,<I>9b, 9c</I> et 9d qui peuvent être comprimées par des vis non repré sentées sur le dessin, de manière à permettre la réalisation d'une liaison rigide de la bague de support 6 et des boulons 4 par serrage de ces vis. Figure 1 shows a cylinder 1 provided with a bottom 2 and a cover 3 which are assembled in the example shown, by four bolts 4a, 4b, 4c and 4d. The cover has in known manner a neck-shaped extension 3a having a passage opening for the piston rod 5. Between the bottom 2 and the lid 3 is mounted on the cylinder a support ring 6 whose inner diameter is slightly greater to the diameter of the cylinder 1. This ring has four openings <I> 7a, 7b, </ I> 7c and <I> 7d </ I> in which open slots 8a, <I> 8b, 8c, </ I> and 8d. In this way, clamping pieces 9a, 9b, 9c and 9d are made which can be compressed by screws not shown in the drawing, so as to allow the realization of a rigid connection of the support ring 6 and bolts 4 by tightening these screws.
Deux tourillons 10a et 10b prévus sur la bague de support 6 servent d'axe d'oscillation du cylindre. L'exemple de réalisation n'est pas restreint à une application à des cylindres comportant quatre bou lons, au contraire, cette disposition peut être mise en oeuvre de la même manière pour des cylindres plus petits comportant par exemple deux boulons ou pour des cylindres plus grands comportant plus de quatre boulons.Two pins 10a and 10b provided on the support ring 6 serve as axis of oscillation of the cylinder. The exemplary embodiment is not restricted to application to cylinders having four bolts, on the contrary, this arrangement can be implemented in the same way for smaller cylinders comprising for example two bolts or for cylinders more large with more than four bolts.
