Abstract

This invention consists of a silicone body (1) in which steel bars (2) are inlaid to confer mechanical characteristics to the assembly. The body is provided with a cavity (3) in its center to receive the piece to be rectified. This tool is manufactured by using a model of the piece to be grinding obtained by vacuum casting technology. When the silicone is cast, both the model and the steel bars are found inside the mold. Afterwards, the model is extracted and we obtain in this way the tool with the hole that reproduces the geometry of the piece to be rectified, the steel bars being lodged in the silicone. This device allows a fast assembly of the piece in the magnetic plate of the rectifier and a correct placement in it due to the adherence produced by the steel bars.

Description

Útil de silicona para rectificado de alta precisión de piezas no magnéticas.Silicone tool for high grinding precision of non-magnetic parts.

Sector de la técnicaTechnical sector

La invención se encuadra en el sector técnico de la ingeniería mecánica, más concretamente en la ingeniería de precisión para la rectificación mecánica de superficies no magnéticas.The invention falls within the technical sector of mechanical engineering, more specifically in the engineering of precision for mechanical surface grinding not magnetic

Estado de la técnicaState of the art

Actualmente, las mordazas utilizadas para el rectificado permiten buena planitud pero no un paralelismo de alta precisión en piezas que previamente no posean una buena perpendicularidad de sus caras además presentan el inconveniente añadido de que pueden dañar los materiales frágiles, llegando en ocasiones a ocasionar grietas de apariencia notable. Por lo tanto surge la necesidad de diseñar un dispositivo que permita el solventar el problema de un paralelismo no adecuado mostrado por las mordazas actuales y la sujeción de piezas no magnéticas.Currently, the jaws used for rectified allow good flatness but not a high parallelism precision in parts that previously do not have a good perpendicularity of their faces also have the disadvantage added that they can damage fragile materials, coming in occasions to cause cracks of remarkable appearance. Thus the need arises to design a device that allows the solve the problem of an inadequate parallelism shown by the current jaws and the clamping of non-magnetic parts.

El nuevo útil resuelve estos problemas permitiendo rectificar materiales vitrocerámicos así como cualquier otro material no magnético, de forma que se obtiene muy buena planitud y paralelismo (tolerancias inferiores a 5 \mum). Asimismo, su cuerpo de silicona le otorga la flexibilidad necesaria para no ocasionar daños a la pieza pero es, a la vez, suficientemente rígido para garantizar una buena sujeción de la pieza durante la operación de rectificado. Este útil asegura la correcta adherencia de la pieza al plato de la rectificadora debido a que tiene embutidas barras de acero que fijan el conjunto al plato magnético de la máquina.The new tool solves these problems allowing to rectify glass ceramic materials as well as any other non-magnetic material, so that you get very good flatness and parallelism (tolerances below 5 µm). Also, its silicone body gives you the necessary flexibility so as not to cause damage to the piece but it is, at the same time, rigid enough to ensure a good grip on the piece during the grinding operation. This tool ensures the correct adhesion of the piece to the plate of the grinding machine because to which it has embedded steel bars that fix the set to the plate  magnetic machine.

Descripción detallada de la invenciónDetailed description of the invention

El objeto de invención consta de un cuerpo de silicona en el cual se embuten barras de acero con el fin de conferir características magnéticas al conjunto. El centro del cuerpo está dotado de una cavidad que se ajusta perfectamente a las dimensiones de la pieza a rectificar. En caso de que sea necesario se le pueden incorporar elementos de sujeción adicionales para mejor ajuste de la pieza al plato de la rectificadora.The object of the invention consists of a body of silicone in which steel bars are embedded in order to confer magnetic characteristics to the set. The center of body is equipped with a cavity that fits perfectly dimensions of the piece to rectify. In case it is necessary additional fasteners can be incorporated for better adjustment of the piece to the plate of the grinder.

Este dispositivo permite un montaje rápido de la pieza en el plato magnético de la rectificadora, además de garantizar una correcta colocación de la pieza en el mismo. La adherencia se logra por la presencia de las barras magnéticas de acero, que unen el útil al plato. A su vez, el útil fija la posición de la pieza por el rozamiento estático entre las paredes del cuerpo de silicona y las caras laterales de la misma.This device allows quick assembly of the piece on the magnetic plate of the grinder, in addition to guarantee a correct placement of the piece in it. The adhesion is achieved by the presence of the magnetic bars of steel, which attach the tool to the plate. In turn, the tool sets the position of the piece by static friction between the walls of the silicone body and the lateral faces thereof.

De esta forma queda resuelto el problema de rectificar cualquier pieza no magnética, suponiendo una mayor ventaja frente a las mordazas de precisión en el caso de materiales vitrocerámicos, ya que éstos pueden ser dañados por las mordazas debido a su gran fragilidad.In this way the problem of rectify any non-magnetic piece, assuming greater advantage over precision jaws in the case of materials ceramic hobs, since these can be damaged by the jaws Due to its great fragility.

Modos de realización de la invenciónEmbodiments of the invention

El útil se fabrica mediante e 1 empleo de un modelo de la pieza que se desea rectificar haciendo uso de la tecnología de colado en vacío. Cuando la silicona es colada, en el interior del molde se encuentran no sólo el modelo sino también las barras de acero. Posteriormente se extrae el modelo de la pieza, quedando en el útil (formado a partir de la silicona colada) un hueco que reproduce la geometría exacta de la pieza a rectificar. Las barras de acero, al no ser extraídas, quedan formando parte del cuerpo de silicona.The tool is manufactured by means of the use of a model of the piece to be rectified using the vacuum casting technology. When the silicone is cast, in the Inside the mold are not only the model but also the steel bars. Later the model of the piece is extracted, remaining in the tool (formed from cast silicone) a hollow that reproduces the exact geometry of the piece to rectify. The steel bars, not being extracted, remain part of the silicone body

El cuerpo de silicona (1) presenta una forma rectangular puesto que ésta es la geometría apropiada para la sujeción en el plato magnético de la rectificadora; en su interior se embuten dos barras de acero (2) para que el conjunto adquiera características magnéticas.The silicone body (1) has a shape rectangular since this is the appropriate geometry for the clamping on the magnetic plate of the grinder; inside two steel bars (2) are inserted so that the assembly acquires magnetic characteristics

Por último queda que resaltar el hueco (3) que reproduce perfectamente en el cuerpo de silicona (1) la geometría de la pieza a rectificar permitiendo de esta manera un montaje rápido y una adecuada sujeción.Finally it is necessary to highlight the hole (3) that perfectly reproduces in the silicone body (1) the geometry of the piece to be rectified thus allowing assembly Fast and adequate support.

El modelo descrito tiene un gran campo de aplicación industrial en la ingeniería de precisión porque permite mecanizar todo tipo de materiales y en especial vitrocerámicos, mediante sujeción magnética. Su aplicación más concreta, es el rectificado de piezas de Zerodur®, que es un material de bajo coeficiente de dilatación térmica que lo hace muy empleado en tecnologías de medida de alta precisión, microlitografía, mecánica de alta estabilidad y en especial en astronomía.The described model has a large field of industrial application in precision engineering because it allows machining all types of materials and especially glass ceramic, by magnetic support. Its most concrete application is the Zerodur® parts grinding, which is a low material coefficient of thermal expansion that makes it widely used in high precision measurement technologies, microlithography, mechanics High stability and especially in astronomy.
