Description

SISTEMA DE GUIADO PARA DESPLAZAMIENTO LONGITUDINAL GUIDE SYSTEM FOR DISPLACEMENT LONGITUDINAL

La presente memoria descriptiva se refiere, como su título indica, a un sistema de guiado para desplazamiento longitudinal, del tipo de los utilizados en máquinas herramienta que realizan el desplazamiento longitudinal sobre dos bancadas independientes y paralelas, caracterizado porque utiliza unos patines flotantes sobre la guía de desplazamiento esclava mediante la incorporación de unas guías de desplazamiento transversalmente dispuestas sobre la guía de desplazamiento longitudinal, dotando de esta forma de posibilidad de movimiento tanto longitudinal como transversal a la máquina con respecto a la bancada solidaria con el suelo, manteniendo la guía de desplazamiento maestra, dotada de los oportunos medios de accionamiento, únicamente con desplazamiento longitudinal con respecto a su bancada. The present specification refers, as its title indicates, to a guidance system for longitudinal displacement, of the type used in machine tools that perform longitudinal displacement on two independent and parallel benches, characterized in that it uses floating skates on the guide Slave displacement by incorporating displacement guides transversely arranged on the longitudinal displacement guide, thus providing the possibility of both longitudinal and transverse movement to the machine with respect to the supportive bench with the ground, maintaining the displacement guide master, equipped with the appropriate means of actuation, only with longitudinal displacement with respect to its bed.

En la actualidad son ampliamente conocidos múltiples y variados tipos de máquinas herramienta y otros dispositivos que, debido a su gran tamaño, utilizan para su desplazamiento longitudinal dos guías de desplazamiento paralelas, ubicadas sobre sendas bancadas solidarizadas con el suelo mediante una cimentación de hormigón. Ejemplos de este tipo de máquinas pueden ser cualquier maquina de mecanizado, corte, taladrado, remachado, etc.. , por ejemplo de tipo pórtico, utilizadas en la fabricación o manipulación de objetos de grandes dimensiones, tal y como podemos encontrar descrito en la Patente Europea 97117832 quot;Máquina tipo pórtico móvil para corte de bloques de granito, mármol y roca en general, y plantaquot;. Una de las guías de desplazamiento, la denominada guía maestra, dispone de los oportunos motores que propician el desplazamiento de la máquina sobre las guías, sirviendo la otra guía desplazamiento, denominada guía esclava, unicamente para proporcionar la necesaria estabilidad y equilibrio en el desplazamiento. At present, multiple and varied types of machine tools and other devices are widely known and, due to their large size, use two parallel displacement guides for longitudinal displacement, located on benches in solidarity with the ground by means of a concrete foundation. Examples of this type of machines can be any machine for machining, cutting, drilling, riveting, etc., for example of gantry type, used in the manufacture or handling of large objects, as we can find described in the Patent European 97117832 "Mobile gantry type machine for cutting blocks of granite, marble and rock in general, and plantaquot ;. One of the displacement guides, the so-called master guide, has the appropriate motors that promote the movement of the machine on the guides, the other displacement guide, called a slave guide, serving only to provide the necessary stability and balance in the displacement.

En gran número de estas aplicaciones de mecanizado de precisión, por ejemplo en la industria aeronáutica, es necesaria una alta precisión en el desplazamiento longitudinal de la máquina, lo cual obliga a que el posicionamiento de las guías longitudinales sobre sus bancadas se realice de una manera tremendamente precisa, con una enorme reigidez, cuidando que el paralelismo entre ambas guías se mantenga dentro de unas estrictas tolerancias, que llegan a ser del orden de centésimas de milímetro. Obviamente este posicionamiento requiere de un proceso de montaje y ajuste largo que influye negativamente en el coste económico de la instalación. In a large number of these precision machining applications, for example in the aeronautical industry, high precision in the longitudinal displacement of the machine is necessary, which requires that the positioning of the longitudinal guides on their benches is carried out in a way tremendously precise, with an enormous stiffness, taking care that the parallelism between both guides remains within strict tolerances, which become of the order of hundredths of a millimeter. Obviously this positioning requires a long assembly and adjustment process that negatively influences the economic cost of the installation.

Además se produce otro problema añadido, y es que dado que las bancadas de soporte de las guías longitudinales están ubicadas sobre una cimentación de hormigón, el paralelismo de estas guías se ve alterado posteriormente por todos aquellos factores que naturalmente afectan al hormigón, como puede ser el natural asentamiento del terreno, los efectos de dilatación o contracción originados por cambios de temperatura o humedad del suelo, etc ... Estas causas naturales introducen cambios en el paralelismo entre las guías que, dada la tremenda precisión y rigidez de guiado requerida, originan unos efectos negativos en el desplazamiento, como durezas, cruzamientos, desgastes anormales, sobreesfuerzo de los motores, averías, etc... que requieren de unas labores correctivas y de mantenimiento frecuentes y económicamente costosas debido a la alta precisión requerida. In addition, another additional problem occurs, and since the support benches of the longitudinal guides are located on a concrete foundation, the parallelism of these guides is subsequently altered by all those factors that naturally affect the concrete, such as the natural settlement of the land, the effects of expansion or contraction caused by changes in soil temperature or humidity, etc ... These natural causes introduce changes in the parallelism between the guides that, given the tremendous precision and rigidity of guidance required, originate negative effects on displacement, such as hardness, crossings, abnormal wear, overexertion of the motors, breakdowns, etc ... that require frequent and economically expensive corrective and maintenance work due to the high precision required.


Para solventar la problemática existente en la actualidad originada por la necesidad de un alto paralelismo entre las guías longitudinales en los sistemas de desplazamiento para maquinas herramientas se ha ideado el sistema de guiado para desplazamiento longitudinal objeto de la presente invención, el cual utiliza unos patines flotantes sobre la guía de desplazamiento esclava realizados mediante la incorporación de unas guías de desplazamiento transversalmente dispuestas sobre la guía de desplazamiento longitudinal. De esta forma la máquina tiene posibilidad de movimiento tanto longitudinal como transversal con respecto a la bancada esclava solidaria con el suelo, manteniendo la guía de desplazamiento maestra, dotada de los oportunos medios de accionamiento, únicamente con desplazamiento longitudinal con respecto a su bancada.
To solve the current problem caused by the need for high parallelism between the longitudinal guides in the displacement systems for machine tools, the guidance system for longitudinal displacement object of the present invention has been devised, which uses floating skates on the slave displacement guide made by incorporating transverse displacement guides arranged on the longitudinal displacement guide. In this way the machine has the possibility of both longitudinal and transverse movement with respect to the slave bed in solidarity with the ground, maintaining the master travel guide, equipped with the appropriate means of operation, only with longitudinal displacement with respect to its bench.

Esta configuración permite que los posibles desplazamientos, irregularidades o faltas de paralelismo en las bancadas sean absorbidas por el desplazamiento transversal del que se ha dotado a la máquina con respecto a la guía de desplazamiento esclava. This configuration allows the possible displacements, irregularities or lack of parallelism in the benches to be absorbed by the transverse displacement that has been provided to the machine with respect to the slave displacement guide.

Este sistema de guiado para desplazamiento longitudinal que se presenta aporta múltiples ventajas sobre los sistemas disponibles en la actualidad siendo la más importante que consigue minimizar los efectos de posibles errores de paralelismo entre las dos bancadas, bien por tolerancias de montajes como por desplazamientos posteriores debido a dilatación, contracción o asentamiento de la base de hormigón de las bancadas, consiguiendo un desplazamiento longitudinal suave y sin atascos. This guidance system for longitudinal displacement that is presented provides multiple advantages over the systems currently available, being the most important that minimizes the effects of possible parallelism errors between the two benches, either due to mounting tolerances or subsequent displacements due to dilation, contraction or settlement of the concrete base of the benches, achieving a smooth longitudinal displacement without jamming.

Otra importante ventaja es que posibilita un procedimiento de montaje de las bancadas y sus correspondientes guías de desplazamiento Another important advantage is that it allows a procedure for mounting the benches and their corresponding travel guides
