Abstract
Description
On connait des machines à dessabler les pièces de fonderie, telles que les culasses de moteur en aluminium, qui comprennent un bâti sur lequel est monté élastiquement un berceau pouvant recevoir une ou plusieurs pièces à dessabler, et des moyens pour faire vibrer le berceau.We know machines for sanding castings, such as aluminum engine heads, which include a frame on which is elastically mounted a cradle which can receive one or more parts to be sanded, and means for vibrating the cradle.
La présente invention a pour objet une machine de ce genre perfectionnée de manière à améliorer son efficacité.The subject of the present invention is a machine of this kind improved so as to improve its efficiency.
La machine selon 1 invention est caractérisée en ce que les moyens pour faire vibrer le berceau sont montés orientables sur celui-ci et en ce qu'elle comporte des moyens pour marteler la ou les pièces à dessabler pendant qu'elles vibrent.The machine according to 1 invention is characterized in that the means for vibrating the cradle are mounted orientable thereon and in that it comprises means for hammering the part or parts to be sanded while they vibrate.
Les moyens pour faire vibrer ' le berceau sont de préférence constitués par une paire de moteurs à balourd portés chacun par une plaque montée pivotante sur l'un des flancs verticaux du berceau.The means for vibrating the cradle are preferably constituted by a pair of unbalance motors each carried by a plate pivotally mounted on one of the vertical sides of the cradle.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation de la machine à dessabler selon l'invention avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en élévation de la
machine;
La Figure 2 en est une vue en plan;
La Figure 3 en est une vue en élévation latérale;
La Figure 4 est une vue en coupe horizontale
d'un détail.An embodiment of the sanding machine according to the invention has been described below, by way of non-limiting example, with reference to the accompanying drawings in which
Figure 1 is an elevational view of the
machine;
Figure 2 is a plan view;
Figure 3 is a side elevation view thereof;
Figure 4 is a horizontal sectional view
of a detail.
Telle qu'elle est représentée au dessin, la machine à dessabler comporte un bâti 1 sur lequel un berceau 2 est lié par des ressorts 3. Ce berceau est formé de deux demi-coquilles pouvant chacune recevoir à leur extrémité une pièce à dessabler 4. Chacun des flancs verticaux du berceau 2 porte une plaque 5 qui peut être orientée autour d'un axe horizontal X-X et porte un moteur à balourd 6, l'ensemble étant disposé de manière à produire une vibration plane dans un plan vertical.As shown in the drawing, the sanding machine has a frame 1 on which a cradle 2 is linked by springs 3. This cradle is formed by two half-shells which can each receive a part to be sanded 4. Each of the vertical sides of the cradle 2 carries a plate 5 which can be oriented around a horizontal axis XX and carries an unbalance motor 6, the assembly being arranged so as to produce a plane vibration in a vertical plane.
Deux marteaux pneumatiques ou hydrauliques 7 sont disposés horizontalement sur des supports 8 qui sont fixés au bâti 1, dans la partie centrale de celui-ci, et pénètrent à l'intérieur du berceau 2. Chacun d'eux est muni d'une bouterolle non représentée. Two pneumatic or hydraulic hammers 7 are arranged horizontally on supports 8 which are fixed to the frame 1, in the central part of the latter, and penetrate inside the cradle 2. Each of them is provided with a not represented.
Chacune des pièces à dessabler 4 repose sur un socle en équerre sur lequel elle peut glisser et est bloquée entre une réglette fixe 9 et une contre-plaque mobile 10 sur laquelle peut agir une paire de vérins pneumatiques ou hydrauliques 11 disposés l'un au-dessus l'autre symétriquement par rapport au plan horizontal contenant l'axe des marteaux 7. La contre-plaque 10 est montée coulissante sur deux colonnes horizontales 12 fixées au berceau, à l'encontre des ressorts de rappel 13.Each of the pieces to be sanded 4 rests on a square base on which it can slide and is locked between a fixed strip 9 and a movable counter plate 10 on which a pair of pneumatic or hydraulic cylinders 11 can act, one arranged at- above the other symmetrically with respect to the horizontal plane containing the axis of the hammers 7. The counterplate 10 is slidably mounted on two horizontal columns 12 fixed to the cradle, against the return springs 13.
Elle porte en son centre une ouverture 14 pour le passage du marteau qui passe également entre la paire correspondante de vérins 11.It carries in its center an opening 14 for the passage of the hammer which also passes between the corresponding pair of jacks 11.
En fonctionnement, les pièces à dessabler 4 sont fixées au berceau 2 par actionnement des vérins 11 qui déplacent les contre-plaques 10 contre l'action des ressorts 13. Les plaques 5 sont orientées de façon à placer dans les directions voulues les axes de vibration Y-Y et Z-Z de chacun des moteurs 6, qui peuvent éventuellement être confondus. Pendant la vibration, les marteaux 7 sont mis en marche de sorte que leurs bouterolles viennent frapper les masselottes 4a des pièces 4.In operation, the parts to be sanded 4 are fixed to the cradle 2 by actuation of the jacks 11 which move the counter plates 10 against the action of the springs 13. The plates 5 are oriented so as to place the axes of vibration in the desired directions YY and ZZ of each of the motors 6, which may possibly be confused. During the vibration, the hammers 7 are set in motion so that their snaps hit the weights 4a of the parts 4.
Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre au contraire toutes les variantes. C'est ainsi que les supports 8 des marteaux 7 pourraient être embarqués sur le berceau 2. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants. This is how the supports 8 of the hammers 7 could be loaded onto the cradle 2.
