ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

La unión por soldadura es una técnica ampliamente establecida en la industria, y su uso se remonta hasta los años treinta del pasado siglo. Esto supuso en su momento un avance muy grande respecto a otro tipo de uniones, tales como los roblones y remaches. Welding bonding is a widely established technique in the industry, and its use dates back to the thirties of the last century. This at the time meant a very large advance compared to other types of joints, such as roblones and rivets.

No obstante, su realización exige de una ténica muy depurada, lo que implica una exigente mano de obra cualificada, caracterizándose por lo tanto por ser un proceso manual donde el resultado final depende en gran medida de la experiencia y destreza del operario. However, its implementation requires a very refined technique, which implies a demanding skilled workforce, therefore being characterized as a manual process where the final result depends largely on the experience and skill of the operator.

El proceso consiste sencillamente en la fusión del metal a través del arco eléctrico y depositar el baño fundido en la unión de la soldadura. El material de aporte se deposita sobre la junta realizada entre las dos piezas a unir. The process simply consists of melting the metal through the electric arc and depositing the molten bath at the weld joint. The contribution material is deposited on the joint between the two pieces to be joined.

Actualmente existen equipos robotizados capaces de realizar trabajos de soldadura con elevada precisión. There are currently robotic equipment capable of welding with high precision.

DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREFERIDA DESCRIPTION OF THE PREFERRED EMBODIMENT

Considerando la numeración adoptada en las figuras, el equipo para el montaje de dos tubos alineados para unirlos mediante soldadura se determina a partir de una mesa de apoyo 1 sobre la cual se fija un plato de garras 2 convencional mediante una chapa de anclaje 3 y unos tornillos radiales 4, a la vez que tal plato de garras 2 incluye un hueco central 5 de donde arranca un eje vertical 6 fijado a la chapa de anclaje 3 mediante un perno central 7, chapa de anclaje 3 que cuenta con unas asas 8 para facilitar el montaje y desmontaje del conjunto. Considering the numbering adopted in the figures, the equipment for the assembly of two aligned tubes for joining them by welding is determined from a support table 1 on which a conventional claw plate 2 is fixed by means of an anchor plate 3 and about radial screws 4, while such a claw plate 2 includes a central hollow 5 from which a vertical axis 6 fixed to the anchor plate 3 starts by means of a central bolt 7, anchor plate 3 which has handles 8 to facilitate the assembly and disassembly of the set.

El eje vertical 6 comprende a su vez un tramo inferior 9 de mayor diámetro y un tramo superior de menor diámetro que incluye un roscado 10 en el que se acopla un soporte de ajuste 11 desplazable verticalmente cuando se gira el mismo, contando tal soporte de ajuste 11 con un roscado superior 12 donde se acopla a su vez una tuerca de ajuste 13 provista de un rebaje anular 14 donde se acopla con giro libre un collarín 15 retenido axialmente con respecto a la tuerca de ajuste 13. The vertical axis 6 in turn comprises a lower section 9 of greater diameter and an upper section of smaller diameter that includes a thread 10 in which a vertically movable adjustment support 11 is engaged when it is rotated, counting such adjustment support 11 with an upper thread 12 where an adjusting nut 13 is provided in turn provided with an annular recess 14 where an axially retained collar 15 is engaged with free rotation with respect to the adjustment nut 13.

El collarín 15 posee pares de orejetas radiales 16 donde se acoplan articuladamente, por uno de sus extremos, unos tirantes 17 que articulan a su vez por sus extremos libres en unas zapatas 18 vinculadas al soporte de ajuste 11 mediante pares de bielas, superiores 19 e inferiores 19', que articulan por sus extremos en las zapatas 18 y soportes de ajuste 11, de manera que las zapatas 18 contactan contra el diámetro interior de un tubo superior 20 a soldar cuando se gira la tuerca de ajuste 13 en un sentido, mientras que cuando esta tuerca de ajuste 13 se gira en sentido contrario, el tubo superior 20 se desvincula y libera de las zapatas 18 y por tanto del soporte de ajuste 11. The collar 15 has pairs of radial lugs 16 where they are articulated, at one of their ends, braces 17 that in turn articulate at their free ends in shoes 18 linked to the adjustment support 11 by means of pairs of connecting rods, upper 19 e bottoms 19 ', which articulate at their ends in the shoes 18 and adjustment brackets 11, so that the shoes 18 contact against the inner diameter of an upper tube 20 to be welded when the adjusting nut 13 is turned in one direction, while that when this adjusting nut 13 is turned in the opposite direction, the upper tube 20 is disconnected and released from the shoes 18 and therefore from the adjustment support 11.

Para proceder a la unión soldada de un tubo inferior 21 y el tubo superior 20, en primer lugar se coloca el tubo inferior 21 apoyándolo sobre una superficie del plato de garras 2 inmovilizándose tal tubo inferior 21 estable y coaxialmente con el eje vertical 6 mediante las garras radiales 22 del plato 2 citado. In order to proceed with the welded connection of a lower tube 21 and the upper tube 20, first the lower tube 21 is placed on a surface of the claw plate 2 immobilizing such a lower tube 21 stably and coaxially with the vertical axis 6 by means of the radial claws 22 of the aforementioned plate 2.

A continuación se coloca el tubo superior 20 apoyándolo por su borde inferior en principio sobre el borde parejo superior adyacente del tubo inferior 21, procediendo después a girar la tuerca de ajuste 13 hasta que las zapatas 18 contactan y hacen tope contra el diámetro interior del tubo superior 20, para después proceder a la separación requerida de los bordes adyacentes de ambos tubos a soldar 20-21, girando el soporte de ajuste 11 en el sentido debido para elevar el tubo superior hacia arriba la medida precisa, y finalmente proceder a soldar en correspondencia con los bordes adyacentes y separados de los citados tubos. The upper tube 20 is then placed by its lower edge in principle on the adjacent upper parallel edge of the lower tube 21, then turning the adjusting nut 13 until the shoes 18 contact and butt against the inner diameter of the tube upper 20, then proceed to the required separation of the adjacent edges of both tubes to be welded 20-21, turning the adjustment support 11 in the proper direction to raise the upper tube up the precise measurement, and finally proceed to weld on correspondence with the adjacent and separated edges of said tubes.

Una vez realizada la unión soldada, se procede a extraer el conjunto de los dos tubos 20-21 soldados liberando el plato de garras 2 y liberando también las zapatas 18 girando la tuerca de ajuste 13 en el sentido debido a fin de que las zapatas 18 dejen de presionar y contactar contra el diámetro interior del tubo superior 20. Once the welded joint is made, the assembly of the two welded tubes 20-21 is removed by releasing the claw plate 2 and also releasing the shoes 18 by turning the adjusting nut 13 in the direction due to the fact that the shoes 18 stop pressing and contacting the inner diameter of the upper tube 20.

Las bielas superiores 19 en su conexión con las zapatas 18 articulan en los mismos ejes que lo hacen los tirantes 17 por uno de sus tramos extremos, encajándose éstos en unos cajeados superiores 23 de las zapatas 18, mientras que las bielas superiores 19 quedan dispuestas por fuera de las zapatas 18 contactando con las caras laterales exteriores de las mismas, igual que ocurre con las bielas inferiores 19'. The upper cranks 19 in their connection with the shoes 18 articulate in the same axes that the braces 17 do for one of their end sections, these being fitted in upper recesses 23 of the shoes 18, while the upper cranks 19 are arranged by outside the shoes 18 by contacting the outer side faces thereof, as is the case with the lower connecting rods 19 '.

2. Declaración motivada según los artículos 29.6 y 29.7 del Reglamento de ejecución de la Ley 11/1986, de 20 de marzo, de Patentes sobre la novedad y la actividad inventiva; citas y explicaciones en apoyo de esta declaración  2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement El documento D01 se refiere a una herramienta articulada para alinear tubos para soldadura u otras operaciones. Está configurado sobre un eje central que está envainado en otro eje central hueco. Mediante tuercas de ajuste asociadas a roscas del eje central se regula una articulación de placas que sostienen tres zapatas que aprietan la pared interior de los tubos. Este documento, por tanto, divulga un equipo para el montaje de tubos alineados para unirlos mediante soldadura que sujeta en su posición el tubo con tres zapatas por medio de pares de bielas (figura 1) tal como está reivindicado en la reivindicación independiente 1. Sin embardo, el objeto reivindicado en 1 se diferencia del documento D01 en lo siguiente: (a) uno de los tubos está sujetado con un plato de garras mientras que en D01 los dos tubos están sujetos con zapatas, (b) cuenta con un sistema de ajuste longitudinal (soporte de ajuste 11) para aproximar los tubos hasta el punto conveniente mientras que en D01 no hay tal sistema. No se considera obvio que un experto en la materia obtenga el objeto la invención a partir del documento D01 el cual se considera el más representativo del estado de la técnica. Document D01 refers to an articulated tool for aligning tubes for welding or other operations. It is configured on a central axis that is sheathed on another hollow central axis. By means of adjusting nuts associated to threads of the central axis, a joint of plates that support three shoes that tighten the inner wall of the tubes is regulated. This document, therefore, discloses an equipment for the assembly of aligned tubes for joining them by welding which holds the tube with three shoes in place by means of pairs of connecting rods (figure 1) as claimed in independent claim 1. Without However, the object claimed in 1 differs from document D01 in the following: (a) one of the tubes is clamped with a claw plate while in D01 the two tubes are fastened with shoes, (b) it has a system of Longitudinal adjustment (adjustment support 11) to approximate the tubes to the convenient point while in D01 there is no such system. It is not considered obvious that a person skilled in the art obtains the object of the invention from document D01 which is considered the most representative of the state of the art. El resto de las reivindicaciones (2 a 9) son dependientes de la primera y por ello tampoco se consideran al alcance del experto en la materia. The rest of claims (2 to 9) are dependent on the first and therefore are not considered within the scope of the person skilled in the art. Por tanto, el objeto de las reivindicaciones de la solicitud es nuevo e implica actividad inventiva (Art. 4º, 6º y 8º de la Ley de Patentes 11/1986). Therefore, the object of the claims of the application is new and involves inventive activity (Art. 4, 6 and 8 of Patent Law 11/1986).
