DESCRIPCION DESCRIPTION
Cámara de distribución de gas en soportes de soldadura SECTOR DE LA TÉCNICA Gas distribution chamber in welding supports TECHNICAL SECTOR
La presente solicitud se refiere a un equipo de soldadura, especialmente un soporte para soldadura TIG, que tiene una cámara de distribución de gas mejorada para facilitar la alimentación de gas durante el giro. The present application refers to a welding equipment, especially a support for TIG welding, which has an improved gas distribution chamber to facilitate the supply of gas during rotation.
ESTADO DE LA TÉCNICA STATE OF THE ART
Es en el campo industrial, en concreto soldadura TIG (del inglés tungsten ¡nert gas) se requiere inyectar argón dentro de las piezas a soldar, de acero inoxidable por ejemplo, para evitar que se oxiden y dañen por las condiciones de la soldadura. It is in the industrial field, specifically TIG welding (from the English tungsten inert gas) that it is required to inject argon into the parts to be welded, stainless steel for example, to prevent them from rusting and being damaged by the welding conditions.
Los operarios encargados de la fabricación en los talleres han de saber realizar las soldaduras alrededor de los tubos o accesorios, inyectado un flujo continuo de gas inerte en el interior de las piezas; muchas veces adoptando posturas incomodas. Para facilitar este trabajo, existen en el mercado muchas mesas giratorias que permiten sujetar la pieza mientras se suelda aunque sigue teniendo un inconveniente. Se ha de elegir entre que gire la pieza o inyectar gas en su interior, realizar las dos operaciones a la vez es inviable. The operators in charge of manufacturing in the workshops must know how to weld around the tubes or accessories, injecting a continuous flow of inert gas inside the parts; often adopting awkward postures. To facilitate this work, there are many rotary tables on the market that allow the part to be held while it is being welded, although it still has a drawback. You have to choose between turning the piece or injecting gas inside it, performing both operations at the same time is not feasible.
Actualmente, los operarios conectan el gas argón dentro de las piezas a soldar, y las piezas se quedan estáticas. Los operarios se mueven alrededor de la pieza con la antorcha. Currently, the operators connect the argon gas inside the pieces to be welded, and the pieces remain static. Operators move around the part with the torch.
El solicitante no conoce ningún tipo de aparato que permita resolver todos estos problemas de forma tan sencilla como la invención. The applicant does not know of any type of apparatus that allows all these problems to be solved in such a simple way as the invention.
BREVE EXPLICACIÓN DE LA INVENCIÓN BRIEF EXPLANATION OF THE INVENTION
La invención consiste en una cámara de distribución de gas, argón normalmente, en soportes para soldadura según la reivindicación primera. Sus diferentes variantes resuelven los problemas reseñados.
El soporte de soldadura comprende un motor conectado a una fijación de la pieza a soldar. Esta conexión se realiza mediante un eje que comprende una parte hueca conectada a una o más salidas de gas en la fijación. La parte hueca tiene uno o más taladros conectados con su alma hueca. Los taladros están dispuestos dentro de una cámara estanca, que forma la invención, conectada a una fuente de gas. El eje puede ser totalmente hueco, o tener una parte sólida conectada al motor. The invention consists of a gas distribution chamber, normally argon, in supports for welding according to the first claim. Its different variants solve the outlined problems. The welding support comprises a motor connected to a fixture of the piece to be welded. This connection is made by means of a shaft comprising a hollow part connected to one or more gas outlets on the fixture. The hollow part has one or more holes connected to its hollow core. The holes are arranged inside a sealed chamber, forming the invention, connected to a gas source. The shaft can be completely hollow, or have a solid part connected to the motor.
Dentro de la fijación se puede disponer una serie de ramales de salida de gas con válvulas de cierre independientes. Así es posible adaptarse a la forma y tamaño de la pieza a soldar, de forma que se introduce el gas por una o más salidas de la fijación, y la pieza se puede situar en el punto más favorable de la fijación. A series of gas outlet branches with independent shut-off valves can be arranged within the fixture. Thus it is possible to adapt to the shape and size of the part to be welded, so that the gas is introduced through one or more outlets of the fixture, and the part can be placed in the most favorable point of the fixture.
Otras variantes se aprecian en el resto de la memoria. Other variants are seen in the rest of the report.

MODOS DE REALIZACIÓN DE LA INVENCIÓN MODES OF EMBODIMENT OF THE INVENTION
A continuación, se pasa a describir de manera breve un modo de realización de la invención, como ejemplo ilustrativo y no limitativo de ésta. Next, an embodiment of the invention is briefly described, as an illustrative and non-limiting example of the latter.
El soporte de la realización mostrada en la figura 1 comprende una fijación (1 ) rotatoria conectada a un motor (2) por un eje (3). La fijación (1) permite sujetas la pieza a soldar mediante mordazas o cualquier otro método conocido. El motor (2) posee un controlador para asegurar que cualquier movimiento de giro corresponde a lo deseado. El giro puede ser continuo, parcial, paso a paso... sin que sea demasiado relevante para la invención. Una fuente de gas (4) suministra el gas, normalmente argón, hacia la fijación (1 ).
El eje (3) tiene dos partes. Una parte sólida (31) fijada al motor (2) y una parte hueca (32), hueca, fijada a la fijación (1 ). El interior de la parte hueca (32) del eje (3) está comunicado con la fijación (1 ), con comunicación fluida de forma que el gas puede pasar del interior de la parte hueca (32) a la fijación (1 ) y de ahí a la pieza. La fijación (1 ) puede tener una serie de ramales, con válvulas independientes, para escoger por dónde surge el gas. The support of the embodiment shown in Figure 1 comprises a rotating fixture (1) connected to a motor (2) by a shaft (3). Fixation (1) allows the piece to be welded to be held by clamps or any other known method. The motor (2) has a controller to ensure that any turning movement corresponds to what is desired. The rotation can be continuous, partial, step by step... without being too relevant for the invention. A gas source (4) supplies the gas, usually argon, to the fixture (1). The shaft (3) has two parts. A solid part (31) fixed to the motor (2) and a hollow part (32), hollow, fixed to the fixing (1). The interior of the hollow part (32) of the shaft (3) is in communication with the fixture (1), with fluid communication so that the gas can pass from the interior of the hollow part (32) to the fixture (1) and from there to the piece. The fixing (1) can have a series of branches, with independent valves, to choose where the gas comes from.
La conexión entre la parte hueca (32) del eje (3) y la fuente de gas (4) se puede realizar mediante una cámara (5) estanca conectada a la fuente de gas (4) y atravesada por el eje (3) esta cámara (5) tiene sendos rodamientos (6) en sus extremos, con juntas de estanqueidad para evitar la salida indeseada del gas. La parte hueca (32) del eje (3) tiene una serie de taladros (33) que comunican con la cámara (5) para permitir el paso del gas hacia la fijación (1). De esta forma, se asegura el suministro de gas a la fijación independientemente de la posición del eje (3) y del número de vueltas o la velocidad de giro.
The connection between the hollow part (32) of the shaft (3) and the gas source (4) can be made by means of a sealed chamber (5) connected to the gas source (4) and crossed by the shaft (3). The chamber (5) has two bearings (6) at its ends, with sealing gaskets to prevent the unwanted exit of gas. The hollow part (32) of the shaft (3) has a series of holes (33) that communicate with the chamber (5) to allow the passage of gas towards the fixing (1). In this way, the supply of gas to the fixture is ensured regardless of the position of the shaft (3) and the number of turns or the speed of rotation.
