PORTA-HERRAMIENTA DE DOBLE EJE MOTORIZADO Sector de la técnica DOUBLE-AXIS MOTORIZED TOOL HOLDER Technical sector
La presente invención está relacionada con los dispositivos porta-herramientas de lijado o pulido, particularmente con los dispositivos de este tipo que incorporan herramientas montadas mediante ejes excéntricos respecto del eje axial de la herramienta, para determinar movimientos de la herramienta roto-orbitales alrededor de un eje central de accionamiento, proponiendo un porta-herramienta en el que la herramienta va dispuesta de manera que realiza una combinación de dos movimientos que son accionados por sendas motorizaciones independientes, lo cual permite un control de los movimientos que posibilita una mayor eficiencia del trabajo operativo de la herramienta. The present invention relates to sanding or polishing tool holders, particularly devices of this type that incorporate tools mounted by eccentric shafts relative to the axial axis of the tool, to determine rotational orbital tool movements around a central axis of drive, proposing a tool holder in which the tool is arranged so that it performs a combination of two movements that are driven by independent motorizations, which allows a control of the movements that allows a greater efficiency of the operative work of the tool.
Estado de la técnica State of the art
Para trabajos como el lijado y pulido de superficies, se utilizan herramientas en forma de lijas o similares, con las cuales se realiza un movimiento de fricción sobre las superficies de aplicación, existiendo aparatos provistos con dispositivos porta-herramientas que realizan esas operaciones de manera motorizada. For works such as sanding and polishing surfaces, tools in the form of sandpaper or similar are used, with which a friction movement is performed on the application surfaces, there are devices provided with tool-holder devices that perform these operations in a motorized manner .
Un tipo de aparatos actuadores de un movimiento motorizado de lijas o similares, son los de accionamiento roto-orbital, en los que unas lijas o similares destinadas para friccionar sobre las superficies de aplicación, se disponen en unos dispositivos porta-herramientas que comprenden un eje primario, al que se aplica una motorización de accionamiento giratorio, y unos ejes secundarios excéntricos respecto del eje primario, los cuales incorporan en montaje giratorio excéntrico respecto de ellos unos soportes sobre los que se disponen las herramientas en forma de lijas o similares. Con este tipo de aparatos se obtiene un movimiento de las lijas o similares describiendo elipses que se van desplazando de posición, lo cual mejora la eficiencia de la fricción sobre las superficies de aplicación, consiguiéndose también un mejor aprovechamiento de las lijas o similares en condiciones adecuadas para su función. En una realización conocida, los aparatos de accionamiento de lijas o similares en movimientos roto-orbitales, disponen de un eje primario que es accionado por una motorización, yendo en posiciones excéntricas respecto de dicho eje primario unos ejes secundarios que giran de manera libre y que incorporan excéntricamente respecto de ellos unos soporte portadores de las lijas o similares. Con esta solución los soportes portadores de las lijas o similares se desplazan en un movimiento rotacional alrededor del eje primario por la acción de la motorización que actúa a dicho eje primario, y en un movimiento rotacional alrededor de los correspondientes ejes secundarios, siendo este segundo movimiento actuado por la fricción del trabajo de las lijas o similares sobre la superficie de aplicación, lo cual supone que este segundo movimiento de las lijas o similares sea aleatorio y sin control, resultando la acción del trabajo de las lijas o similares poco uniforme. One type of actuator apparatus of a motorized movement of sandpaper or the like, are those of rotational-orbital drive, in which some sandpaper or the like intended to friction on the application surfaces, are arranged in tool-holder devices comprising an axis primary, to which a rotary drive motorization is applied, and eccentric secondary axes with respect to the primary axis, which incorporate in an eccentric rotary assembly with respect to them supports on which the tools are arranged in the form of sandpaper or the like. With this type of apparatus, a movement of the sandpaper or the like is obtained by describing ellipses that are shifting from position, which improves the efficiency of friction on the application surfaces, also achieving a better use of the sandpaper or the like in suitable conditions. for your function In a known embodiment, the sandpaper or similar actuators in roto-orbital movements have a primary shaft that is driven by a motorization, going in eccentric positions with respect to said primary axis secondary axes that rotate freely and which eccentrically incorporate with respect to them carrier supports of the sandpaper or the like. With this solution, the supports carrying the sandpaper or the like move in a rotational movement around the primary axis by the action of the motorization that acts on said primary axis, and in a rotational movement around the corresponding secondary axes, this second movement being acted on by the friction of the sandpaper work or the like on the application surface, which means that this second movement of the sandpaper or the like is random and uncontrolled, resulting in the action of the sandpaper work or the like being uneven.
Existen también aparatos, como los de las Patentes US 1430214 y EP 1620229, para accionamiento de lijas o similares en movimientos roto-orbitales, con un eje primario actuado por una motorización y unos ejes secundarios excéntricos que incorporan soportes excéntricos portadores de lijas o similares, estando los ejes secundarios relacionados con el eje primario mediante una transmisión de giro y los soportes portadores de las lijas o similares relacionados con los respectivos ejes secundarios mediante otras transmisiones de giro. Esta solución permite tener un control del movimiento de los soportes portadores de las lijas o similares, tanto en la rotación alrededor del eje primario, como en la rotación alrededor de los ejes secundarios correspondientes; pero al ser dichos movimientos dependientes entre sí, sólo es posible un control de ambos movimientos a la vez, lo cual restringe las posibilidades de utilización de estos aparatos con efectividad en algunos casos, como por ejemplo para operar sobre zonas próximas a los bordes de las superficies de trabajo. Objeto de la invención There are also devices, such as those of US Patents 1430214 and EP 1620229, for driving sanding or the like in rotational-orbital movements, with a primary axis actuated by motorization and eccentric secondary axes incorporating eccentric supports carrying sandpaper or the like, the secondary axes being related to the primary axis by means of a turning transmission and the supports carrying the sandpaper or the like related to the respective secondary axes by means of other turning transmissions. This solution allows to control the movement of the supports carrying the sandpaper or similar, both in the rotation around the primary axis, and in the rotation around the corresponding secondary axes; but since said movements are dependent on each other, only one control of both movements is possible at the same time, which restricts the possibilities of using these devices effectively in some cases, such as to operate on areas near the edges of the work surfaces. Object of the invention
De acuerdo con la invención se propone un porta-herramienta que permite actuar una herramienta del tipo de lija o similar en movimientos roto-orbitales totalmente controlados, para trabajos de lijado, pulido u otros semejantes, sobre superficies de aplicación. According to the invention, a tool holder is proposed that allows a tool of the type of sandpaper or the like to be operated in fully controlled rotational orbital movements, for sanding, polishing or other similar work, on application surfaces.
Este porta-herramienta objeto de la invención comprende un eje primario que es actuado por una primera motorización de giro, al cual está unido en posición excéntrica un soporte porta- herramienta, estando dicho eje primario incorporado en montaje respecto de un conjunto portante, el cual se encuentra sustentado por unos juegos de bielas que están asociados a unos ejes secundarios que son actuados por una segunda motorización independiente de la que actúa al eje primario. De este modo se tiene un porta-herramienta en el que el eje primario desplaza en rotación alrededor de él al soporte porta-herramienta, mientras que los ejes secundarios mueven, por medio de los juegos de bielas, al conjunto portante del soporte porta-herramienta en un movimiento orbital alrededor de un punto central, con lo cual el soporte porta-herramienta realiza un movimiento combinado roto-orbital, con el que se consigue una acción muy uniforme en trabajos de fricción, como lijado o pulido, sobre las superficies de aplicación; estando previsto el giro del eje primario a una alta velocidad y el giro de los ejes secundarios a baja velocidad, de manera que mediante el movimiento que aplica el eje primario la herramienta realiza un matizado sobre la superficie de aplicación, mientras que con el movimiento que aplican los ejes secundarios se elimina la rugosidad. This tool holder object of the invention comprises a primary axis which is actuated by a first rotation motor, to which a tool holder is eccentrically attached, said primary axis being incorporated in assembly with respect to a bearing assembly, which It is supported by sets of connecting rods that are associated with secondary axles that are operated by a second motorization independent of the one acting on the primary axis. In this way there is a tool holder in which the primary axis rotates around it to the tool holder support, while the secondary axes move, by means of the cranksets, to the support assembly of the tool holder support in an orbital movement around a central point, whereby the tool holder supports a combined broken-orbital movement, which achieves a very uniform action in friction work, such as sanding or polishing, on the application surfaces ; the rotation of the primary axis being provided at a high speed and the rotation of the secondary axes at low speed, so that by means of the movement applied by the primary axis the tool makes a nuance on the application surface, while with the movement that Apply secondary shafts roughness is eliminated.
Por otro lado, al estar motorizados de manera independiente el movimiento que se aplica mediante el eje primario y el movimiento que se aplica mediante los ejes secundarios, se puede establecer un control coordinando ambos movimientos, para realizar un recorrido del movimiento orbital en desplazamiento totalmente circular o en desplazamientos parcialmente circulares de vaivén, permitiendo adaptar la operativa del trabajo para unas condiciones óptimas de efectividad y rendimiento en relación con las particularidades de cada zona de las superficies de aplicación, lo cual resulta muy práctico, por ejemplo, para operar en las zonas de los límites de las superficies de aplicación. On the other hand, when the movement that is applied by the primary axis and the movement that is applied by the secondary axes are independently motorized, a control can be established by coordinating both movements, to make a tour of the orbital movement in fully circular displacement or in partially circular reciprocating displacements, allowing the work operation to be adapted for optimal conditions of effectiveness and performance in relation to the particularities of each area of the application surfaces, which is very practical, for example, to operate in the areas of the limits of the application surfaces.
La herramienta del tipo de lija o similar se prevé de forma cuadrada y su montaje de modo que no gira sobre sí misma sino que sólo realiza un movimiento de traslación llevada por el soporte porta-herramienta según las órbitas de movimiento que transmiten el eje primario y los ejes secundarios, con lo cual se consigue que el acabado de la superficie de fricción sea totalmente uniforme, ya que en la zona sobre la que actúa la herramienta la superficie de aplicación es afectada de un modo uniforme por toda la superficie de la herramienta, sin que haya diferencia de acción entre la zona periférica y la zona central de la herramienta como ocurre con las herramientas circulares dotadas de movimiento giratorio sobre sí mismas. Dicho porta-herramienta objeto de la invención resulta por lo tanto de unas características que le hacen ventajoso para la función operativa de actuación mediante una herramienta del tipo de lija o similar, de tal modo que este porta-herramienta adquiere vida propia y carácter preferente respecto de los dispositivos porta-herramientas convencionales de la misma función. The tool of the type of sandpaper or similar is provided in a square way and its assembly so that it does not rotate on itself but only performs a translation movement carried by the tool holder according to the movement orbits that transmit the primary axis and the secondary axes, whereby the friction surface finish is completely uniform, since in the area on which the tool acts the application surface is uniformly affected by the entire surface of the tool, There is no difference in action between the peripheral zone and the central area of the tool, as is the case with circular tools with rotating movement on themselves. Said tool holder object of the invention therefore results in characteristics that make it advantageous for the operative function of operation by means of a tool of the type of sandpaper or the like, such that this tool holder acquires its own life and preferential character with respect to of conventional toolholder devices of the same function.

Descripción detallada de la invención Detailed description of the invention
El objeto de la invención se refiere a un porta-herramienta para trabajos de fricción sobre superficies mediante una lija o similar, con una disposición funcional que permite establecer un control total del trabajo operativo. The object of the invention relates to a tool holder for friction work on surfaces by means of a sandpaper or similar, with a functional arrangement that allows to establish a total control of the operative work.
El porta-herramienta según la invención consta de un conjunto portante (1), respecto del que está incorporado un soporte porta-herramienta (2) destinado para disponer en él una herramienta de fricción en forma de lija o similar. The tool holder according to the invention consists of a support assembly (1), with respect to which a tool holder holder (2) is incorporated, designed to provide a friction tool in the form of sandpaper or the like.
El soporte porta-herramienta (2) está unido en posición excéntrica sobre un eje primario (3) que es actuado por una primera motorización de giro (4) a través de un acoplamiento elástico (8), de forma que al girar dicho eje primario (3) el soporte porta-herramienta (2) se desplaza en movimiento de rotación excéntrica alrededor del mismo. The tool holder (2) is connected in an eccentric position on a primary axis (3) which is actuated by a first rotation motorization (4) through an elastic coupling (8), so that when said primary axis is rotated (3) the tool holder support (2) moves in eccentric rotation movement around it.
El conjunto portante (1) se sustenta mediante unos juegos de bielas (5), los cuales están asociados a unos ejes secundarios (6) que son actuados por una segunda motorización de giro (7), independiente de la primera motorización de giro (4) que actúa al eje primario (3). La segunda motorización de giro (7) está relacionada con uno de los ejes secundarios (6), pudiendo tener los demás ejes secundarios (6) giro libre o estar relacionados por medio de una transmisión de accionamiento de giro con el eje secundario (6) motorizado. The bearing assembly (1) is supported by connecting rod sets (5), which are associated with secondary axles (6) that are operated by a second rotation motorization (7), independent of the first rotation motorization (4). ) acting on the primary axis (3). The second rotation motorization (7) is related to one of the secondary axes (6), the other secondary axes (6) being able to have free rotation or be related by means of a rotation drive transmission with the secondary axis (6) motorized.
Con tal disposición, el giro del eje primario (3) actuado por la primera motorización de giro (4), hace que el soporte porta-herramienta (2) se desplace en rotación excéntrica alrededor de dicho eje primario (3); mientras que el giro de los ejes secundarios (6) actuado por la segunda motorización de giro (7), hace que el conjunto portante (1) se mueva orbitalmente alrededor de un punto central, con lo que el soporte porta-herramienta (2) y, consecuentemente, la herramienta en forma de lija o similar que va incorporada en él, se mueve con un movimiento roto-orbital alrededor del eje primario (3). With such an arrangement, the rotation of the primary axis (3) actuated by the first motorization of rotation (4), causes the tool holder support (2) to move in eccentric rotation around said primary axis (3); while the rotation of the secondary axes (6) acted on by the second rotation motorization (7), causes the bearing assembly (1) to move orbitally around a central point, with which the tool holder (2) and, consequently, the sandpaper or similar tool that goes incorporated into it, it moves with a broken-orbital movement around the primary axis (3).
De este modo, al ser actuados de manera independiente el movimiento que se aplica por medio del eje primario (3) mediante la primera motorización de giro (4) y el movimiento que se aplica por medio de los ejes secundarios (6), actuado por la segunda motorización de giro (7), se puede establecer un control para coordinar de una manera totalmente efectiva ambos movimientos, para el trabajo operativo con la herramienta sobre la superficie de aplicación. Thus, when the movement that is applied by means of the primary axis (3) is activated independently by the first rotation motorization (4) and the movement that is applied by means of the secondary axes (6), actuated by the second rotation motorization (7), a control can be established to coordinate both movements in a totally effective way, for the operative work with the tool on the application surface.
En esas condiciones, se prevé que el giro del eje primario (3), actuado por la primera motorización de giro (4), sea a alta velocidad, del orden de 10.000 rpm; y que el giro de los ejes secundarios (6), actuado por la segunda motorización de giro (7), sea a baja velocidad, en el rango de 50 - 60 rpm. Under these conditions, it is expected that the rotation of the primary axis (3), actuated by the first motorization of rotation (4), is at high speed, of the order of 10,000 rpm; and that the rotation of the secondary axes (6), actuated by the second motorization of rotation (7), is at low speed, in the range of 50-60 rpm.
Para conseguir una acción uniforme sobre la superficie de aplicación, se prevé que la herramienta de trabajo sea cuadrada y no gire sobre sí misma sino que únicamente sea llevada por el soporte porta-herramienta (2) en el movimiento roto-orbital por la combinación de los movimientos que transmiten el eje primario (3) y los ejes secundarios (6). To achieve a uniform action on the application surface, it is envisaged that the work tool is square and does not rotate on itself but is only carried by the tool holder (2) in the broken-orbital movement by the combination of the movements that transmit the primary axis (3) and the secondary axes (6).
