DESCRIPCIÓN DETALLADA DE LA INVENCIÓN DETAILED DESCRIPTION OF THE INVENTION

[0006] El dispositivo de la presente invención comprende bases de soporte (1 ), un soporte (2), un husillo (3) y un flanche móvil (4). [0006] The device of the present invention comprises support bases (1), a support (2), a spindle (3) and a mobile flange (4).

[0007] Las bases de soporte (1 ) se encuentran ubicadas una frente a la otra y comprenden orificios (5) a través de los cuales se inserta el soporte (2), perpendicularmente. El soporte comprende un orificio (6) por donde pasa el extremo superior del husillo, (3) el cual se dispone de forma equidistante a cada una de las bases de soporte. El soporte (2) se puede ajustar al husillo (3) mediante una tuerca superior (7) que se dispone en la cara superior del soporte (2) y opcionalmente una tuerca intermedia superior (8) que se dispone en la cara inferior del soporte. Entre cada tuerca (7, 8) y el soporte (2) se pueden disponer una o más arandelas (9). [0008] Preferentemente, la bases de soporte (1 ) pueden comprender una estructura lateral adicional (10) donde se dispone una ranura (1 1 ) que permite ubicar las bases de soporte (1 ) con mayor facilidad sobre el bloque de cilindros en un motor, mediante pernos que atraviesan dichas ranuras. [0007] The support bases (1) are located facing each other and comprise holes (5) through which the support (2) is inserted, perpendicularly. The support comprises a hole (6) through which passes the upper end of the spindle, (3) which is arranged equidistantly to each of the support bases. The support (2) can be adjusted to the spindle (3) by means of an upper nut (7) which is arranged on the upper face of the support (2) and optionally an upper intermediate nut (8) which is arranged on the underside of the support . Between each nut (7, 8) and the support (2) one or more washers (9) can be arranged. [0008] Preferably, the support bases (1) can comprise an additional lateral structure (10) where a groove (1 1) is arranged, which makes it possible to locate the support bases (1) more easily on the cylinder block in a motor, through bolts that go through these grooves.

[0009] El flanche móvil (4) se encuentra compuesto por una placa inferior (12) y una placa superior (13). La placa superior está compuesta por dos partes (131 , 132). Cada una de estas partes comprende una pluralidad de orificios (14) para recibir pernos (15). La placa inferior (12) comprende orificios (16), a través de los cuales pasan los pernos (15) que se acoplan a cualquiera de los orificios (14) de las partes (131 , 132) que conforman la placa superior (13), uniendo así la placa inferior (12) y la placa superior (13) como se puede ver en la FIG. 2. Las partes (131 , 132) de la placa superior pueden estar separadas axialmente entre sí a diferentes distancias, como se ilustra en la FIG. 3A y en la FIG. 3B, haciendo que el flanche móvil (4) sea ajustable al diámetro de la camisa de cilindro a extraer o a insertar. Esto permite que el dispositivo de la presente invención pueda ser empleado para la extracción o la inserción de camisas de cilindro de cualquier motor Diesel, sin importar su tamaño. [0009] The movable flange (4) is composed of a lower plate (12) and an upper plate (13). The upper plate is composed of two parts (131, 132). Each of these parts comprises a plurality of holes (14) for receiving bolts (15). The lower plate (12) comprises orifices (16), through which pass the bolts (15) which are coupled to any of the holes (14) of the parts (131, 132) that make up the upper plate (13) , thus joining the lower plate (12) and the upper plate (13) as can be seen in FIG. 2. The parts (131, 132) of the top plate can be axially spaced from each other at different distances, as illustrated in FIG. 3A and in FIG. 3B, making the movable flange (4) adjustable to the diameter of the cylinder liner to be extracted or inserted. This allows the device of the present invention to be used for the extraction or insertion of cylinder liners of any diesel engine, regardless of its size.

[0010] Los pernos (15) pueden insertarse desde la placa inferior (12) del flanche o desde la placa superior (13) del flanche. [0010] The bolts (15) can be inserted from the lower plate (12) of the flange or from the upper plate (13) of the flange.

[0011] Tanto la placa superior (13) como la placa inferior (12) comprenden un agujero central (17, 18) para recibir el extremo inferior del husillo (3). Las placas (12, 13) se ajustan al husillo (3) mediante una tuerca intermedia inferior (19) que se dispone en la cara superior de la placa superior (13) y una tuerca inferior (20) que se dispone en la cara inferior de la placa inferior (12) del flanche móvil (4). Entre las tuercas (19, 20) y el flanche móvil se pueden disponer una o más arandelas (21 ). [0011] Both the upper plate (13) and the lower plate (12) comprise a central hole (17, 18) for receiving the lower end of the spindle (3). The plates (12, 13) are adjusted to the spindle (3) by means of a lower intermediate nut (19) which is arranged on the upper face of the upper plate (13) and a lower nut (20) which is disposed on the lower face of the lower plate (12) of the mobile flange (4). Between the nuts (19, 20) and the movable flange one or more washers (21) can be arranged.

[0012] En una modalidad preferente de la invención, la placa inferior (12) comprende dos orificios (16) que reciben dos pernos (15) que se acoplan, cada uno, con un orificio (14) de la parte correspondiente de la placa superior (13). Preferentemente, cada una de las partes (131 , 132) de la placa superior comprende tres orificios (14) y cualquiera puede recibir el perno (15) que une ambas placas. Sin embargo, la invención puede comprender cualquier número de orificios y de pernos que aseguren la unión de ambas placas del flanche móvil. [0012] In a preferred embodiment of the invention, the lower plate (12) comprises two orifices (16) receiving two bolts (15) which are each coupled with an orifice (14) of the corresponding part of the plate superior (13). Preferably, each of the parts (131, 132) of the upper plate comprises three holes (14) and anyone can receive the bolt (15) joining both plates. However, the invention can comprise any number of holes and bolts that ensure the joining of both plates of the mobile flange.

[0013] Preferentemente, los orificios (14) de cada una de las partes de la placa superior (13) que reciben los pernos (15), son equidistante al agujero central de la placa superior. [0013] Preferably, the holes (14) of each of the parts of the upper plate (13) that receive the bolts (15) are equidistant to the central hole of the upper plate.
