Description
Herramienta para tratamiento de superficies y recambio para dicha herramienta.Tool for surface treatment and spare part for said tool.
La presente invención hace referencia a una herramienta para tratamiento de superficies y un recambio de tratamiento superficial para dicha herramienta.The present invention refers to a tool for surface treatment and a replacement of surface treatment for said tool.
Más en concreto, la presente invención se refiere a herramientas para tratamiento de superficies del tipo que comprende una base denominada habitualmente plato que presenta una primera cara con un elemento de conexión a un eje de accionamiento por giro y una segunda cara opuesta a ésta con una superficie para unión mecánica por contacto (por ejemplo, mediante un sistema velcro) con un recambio laminar de tratamiento superficial. Dichas herramientas presentan la ventaja de ser fáciles de construcción y de permitir el fácil intercambio de recambios o discos de tratamiento superficial sin necesidad de cambio del plato. Cuando el disco presenta signos externos de deterioro gracias a la conexión mecánica por contacto el disco es simplemente arrancado de la superficie y sustituido por otro nuevo. También es posible con un mismo plato utilizar discos para diferentes operaciones (lijado, pulido ...). Los platos de tipo conocido que constituyen este tipo de herramientas exclusivamente presentan forma de platillo siendo la segunda cara plana, como consecuencia de la disposición laminar del disco. Sin embargo, presentan el problema para tratamiento de superficies irregulares (con radios de curvatura, etc.) de que el disco se desgasta de manera no uniforme y además se producen vibraciones debido al poco apoyo del disco sobre la superficie a tratar. Como consecuencia, para tratamiento de superficies no planas con este tipo de herramientas se requiere la utilización de operarios altamente cualificados.More specifically, the present invention is refers to tools for surface treatment of the type that it comprises a base usually called a plate that has a first face with a connecting element to a drive shaft by turning and a second face opposite it with a surface for mechanical contact bonding (for example, by a system Velcro) with a laminar replacement surface treatment. These tools have the advantage of being easy to build and to allow the easy exchange of spare parts or discs of surface treatment without changing the plate. When he disc shows external signs of deterioration thanks to the connection mechanical contact the disk is simply ripped from the surface and replaced by a new one. It is also possible with a same plate use discs for different operations (sanding, polished ...). Dishes of known type that constitute this type of tools exclusively have a saucer shape being the second flat face, as a consequence of the laminar arrangement of the disk. However, they present the problem for treatment of irregular surfaces (with radii of curvature, etc.) that the disc wears unevenly and also occur vibrations due to the little support of the disk on the surface to try. As a consequence, for treatment of non-flat surfaces with this type of tools the use of highly qualified operators.
