Description

Soporte de tres patas para avellanador.Three-leg hob holder.

Estado de la técnicaState of the art

La invención revelada en la presente memoria pertenece al campo de la técnica de las herramientas para operaciones de avellanado de taladros.The invention disclosed herein it belongs to the field of tools technique for drilling countersink operations.

En industrias como la aeronáutica, es común el uso extensivo de remaches como medio de unión de las piezas que conforman la estructura primaria. Para el mantenimiento de la línea aerodinámica, es necesario avellanar los taladros para los remaches, de forma que las cabezas de dichos remaches queden ocultas y no entorpezcan el flujo del aire. Las operaciones de taladrado y avellanado son origen de una gran cantidad de defectos de calidad, que redundan en un alto coste de inspección y reparación. Los defectos más comunes se deben a las marcas que se provocan en la superficie de paneles por una mala evacuación de la viruta, o a la aparición de huecos no aceptables entre la cabeza del remache y el avellanado, normalmente causados porque el avellanado no es coaxial con el taladro.In industries such as aeronautics, the extensive use of rivets as a means of joining the pieces that They make up the primary structure. For line maintenance aerodynamics, it is necessary to countersink the holes for the rivets, so that the heads of these rivets are hidden and not hinder the flow of air. Drilling operations and Countersunk are the origin of a lot of quality defects, which result in a high cost of inspection and repair. The most common defects are due to the marks that are caused in the panel surface due to bad chip evacuation, or to the appearance of unacceptable gaps between the head of the rivet and the countersunk, normally caused because countersinking is not coaxial with the drill.

Para conseguir avellanados coaxiales con los taladros es necesario un útil o dispositivo de soporte que mantenga la posición de la herramienta de taladrado perpendicular a la superficie exterior. Esto resulta complicado y muy dependiente de la habilidad del operario cuando las superficies son curvadas, ya que el apoyo de las herramientas es malo.To get coaxial countersunk with drills a tool or support device is needed to maintain the position of the drilling tool perpendicular to the outer surface. This is complicated and very dependent on the Operator ability when surfaces are curved, since Tool support is bad.

Son conocidas en el estado de la técnica, reguladores micrométricos de profundidad como los revelados en las patentes US2,402,353 y US3,028,774. En estas patentes, se utiliza una falda cilíndrica hueca para el apoyo de la herramienta sobre la superficie de trabajo. Dicha falda cuenta con dos aperturas diametralmente opuestas para facilitar la evacuación de la viruta y con una rosca interior para su unión al regulador de profundidad. El problema de estas herramientas es que el apoyo solo es bueno sobre superficies planas, por lo que no garantizan la coaxialidad del avellanado si dichas superficies están curvadas. Además el desalojo de la viruta no siempre es bueno, lo que provoca frecuentes marcas en la superficie.They are known in the state of the art, micrometric depth regulators such as those disclosed in the US2,402,353 and US3,028,774. In these patents, it is used a hollow cylindrical skirt for the support of the tool on the work surface. This skirt has two openings diametrically opposed to facilitate chip evacuation and with an internal thread for attachment to the depth regulator. He problem with these tools is that support is only good about flat surfaces, so they do not guarantee the coaxiality of the countersunk if these surfaces are curved. In addition the eviction Chip is not always good, which causes frequent marks on the surface.

No se conoce en el estado de la técnica ninguna herramienta que permita combinar un buen apoyo con una buena evacuación de la viruta, lo que sería beneficioso desde el punto de vista de la calidad del producto.None of the prior art is known. tool that allows combining good support with good chip evacuation, which would be beneficial from the point of View of product quality.

Descripción de la invenciónDescription of the invention

De acuerdo con la presente invención un dispositivo de apoyo para una herramienta de avellanado consiste en un cuerpo, normalmente cilíndrico, con un agujero con rosca interior para el alojamiento del casquillo que permite el movimiento de rotación del eje de la herramienta de avellanado. Dicho cuerpo dispone además de medios de unión a un regulador micrométrico de profundidad, que normalmente será mediante un conjunto de dientes mecanizados en una sección circular del exterior del cuerpo cilíndrico.According to the present invention a Support device for a countersink tool consists of a body, normally cylindrical, with a hole with internal thread for the housing of the bushing that allows the movement of rotation of the countersink tool shaft. Said body It also has connection means to a micrometric regulator of depth, which will usually be through a set of teeth machined in a circular section of the outside of the body cylindrical.

Dicho cuerpo se extiende en la dirección de su eje en forma de tres patas de apoyo distribuidas uniformemente. El uso de tres patas en lugar de un cilindro permite el apoyo en cualquier superficie por curvada que ésta sea, manteniendo la herramienta en la dirección localmente perpendicular a la superficie de trabajo y garantizando así la coaxialidad con el taladro y evitando la aparición de huecos entre el avellanado y la cabeza del remache.Said body extends in the direction of its Shaft in the form of three support legs evenly distributed. He use of three legs instead of a cylinder allows support in any surface, no matter how curved it is, maintaining the tool in the direction locally perpendicular to the surface working and thus guaranteeing coaxiality with the drill and avoiding the appearance of gaps between the countersink and the head of the rivet.

Dichas patas se extenderán de tal forma que permitan mantener unas aberturas entre ellas lo suficientemente amplias para el desalojo de la viruta del interior del dispositivo, evitando que dicha viruta impulsada por el eje de la herramienta provoque marcas en la superficie de trabajo de la pieza.These legs will extend in such a way that allow to maintain openings between them sufficiently wide for the eviction of the chip inside the device, preventing said chip driven by the tool axis cause marks on the work surface of the part.

Se consigue de esta forma de acuerdo con la presente invención un buen apoyo del dispositivo de avellanado sobre superficies de trabajo curvadas, un avellanado coaxial con el taladro, evitando huevos entre la cabeza del remache y el avellanado y una mejor evacuación de la viruta, evitando así la aparición de marcas en la superficie de la pieza.It is achieved in this way according to the present invention a good countersink device support on curved work surfaces, a coaxial countersink with the drill, avoiding eggs between the head of the rivet and countersunk and a better evacuation of the chip, thus avoiding the appearance of marks on the surface of the piece.
