DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREFERIDADESCRIPTION OF THE PREFERRED EMBODIMENT
Haciendo referencia a la numeración adoptada en las figuras, la herramienta manual perfeccionada comprende un brazo fijo 1 y otro móvil 2, incluyendo ambos respectivamente, una mordaza fija 3 y una mordaza móvil 4. El brazo fijo 1 constituye el cuerpo principal de la herramienta. La herramienta de la invención incluye un mecanismo de bloqueo o enclavamiento para asegurar la fijación por presión de una o varias piezas 5 situadas entre ambas mordazas 3 y 4. Ese mecanismo de bloqueo o enclavamiento se determina a partir de una biela 6 que se acopla articuladamente por un punto extremo 7 sobre un émbolo 8 que se conduce en un orificio guía 9 del brazo fijo 1. En cambio, el otro extremo de la biela 6 se acopla articuladamente sobre un punto intermedio 10 del brazo móvil 2, vinculándose también articuladamente ambos brazos 1 y 2 en un punto extremo 11.Referring to the numbering adopted in the figures, the perfected hand tool It comprises a fixed arm 1 and a movable arm 2, including both respectively, a fixed jaw 3 and a movable jaw 4. The fixed arm 1 constitutes the main body of the tool. The tool of the invention includes a locking or interlocking mechanism to ensure the pressure fixing of one or more parts 5 located between both jaws 3 and 4. That locking or interlocking mechanism is determined from a connecting rod 6 that is articulated by an end point 7 on a plunger 8 which is driven in a guide hole 9 of the fixed arm 1. Instead, the other end of the connecting rod 6 is articulatedly coupled on an intermediate point 10 of the movable arm 2, both arms being articulated jointly 1 and 2 at an extreme point 11.
Por otro lado, el brazo móvil 2 queda vinculado a un cilindro 12 solidario del émbolo 8 y en el cual se rosca la mordaza móvil 4.On the other hand, the movable arm 2 is linked to a cylinder 12 integral with the piston 8 and into which the movable jaw 4 is threaded.
El brazo móvil 2 incluye además una barra a modo de leva 13 que está articulada en un punto superior 14 de dicho brazo móvil 2, estando destinada dicha leva 13 para facilitar el desenclavamiento o desbloqueo del brazo móvil 2 y en general del conjunto de la herramienta de la invención. La mordaza fija 3, aunque forma parte integrante del brazo fijo 1 como una prolongación acodada, dicha mordaza fija 3 podría estar determinada por un elemento independiente a modo de postizo fijado al citado brazo fijo 1. Las dos mordazas 3 y 4 se encuentran enfrentadas, de tal manera que para situar la herramienta en una posición activa de bloqueo, será preciso bascular el brazo móvil 2 hasta que el mismo haga tope contra el brazo fijo 1, de tal forma que en este proceso, se desplazará el émbolo 8 conducido en el orificio guía 9 del brazo fijo 1 acercándose la mordaza móvil 4 a la mordaza fija 3, entre las cuales se encuentran las piezas a fijar 5 (figura 1). En esta posición de enclavamiento los dos puntos de articulación 7 y 10 de la biela 6 y también el punto de articulación 11 que vincula ambos brazos 1 y 2, se encuentran ventajosamente alineados, en una misma dirección.The mobile arm 2 further includes a cam-like bar 13 that is articulated at an upper point 14 of said mobile arm 2, said cam 13 being intended to facilitate the unlocking or unlocking of the mobile arm 2 and in general of the tool assembly of the invention. The fixed jaw 3, although it forms an integral part of the fixed arm 1 as an elongated extension, said fixed jaw 3 could be determined by an independent post-shaped element fixed to said fixed arm 1. The two jaws 3 and 4 are facing each other, in such a way that to place the tool in an active locking position, it will be necessary to swing the movable arm 2 until it stops against the fixed arm 1, so that in this process, the piston 8 driven in the guide hole 9 of the fixed arm 1 the mobile jaw 4 approaching the fixed jaw 3, among which are the pieces to be fixed 5 (figure 1). In this interlocking position the two articulation points 7 and 10 of the connecting rod 6 and also the articulation point 11 which links both arms 1 and 2, are advantageously aligned, in the same direction.
Por otra parte, para proceder al desbloqueo del conjunto de la herramienta se actuará sobre el tramo extremo inferior de la leva 13, de tal manera que el tramo opuesto de la misma presionará sobre el brazo fijo 1, con lo cual, se producirá instantáneamente el desbloqueo de la herramienta donde participa y ayuda también un resorte 15 establecido en el interior del orificio guía 9 del brazo fijo 1. Este resorte 15 hace tope por un extremo contra el émbolo 8 del brazo fijo 1 empujándolo hacia abajo, mientras que el extremo opuesto superior de ese resorte 15 hace tope contra un asiento 16 del brazo fijo 1 establecido en correspondencia con la parte de arriba del aludido orificio guía 9. En la posición de bloqueo de la herramienta, el resorte o muelle 15 queda comprimido, de manera que en la operación de desbloqueo, ese muelle ayudará en dicha operación.On the other hand, to unblock the tool assembly, the lower end section of the cam 13 will be actuated, so that the opposite section of the tool will press on the fixed arm 1, whereby the unlocking of the tool where a spring 15 is established and also helps inside the guide hole 9 of the fixed arm 1. This spring 15 stops at one end against the piston 8 of the fixed arm 1 by pushing it down, while the opposite end The upper part of that spring 15 stops against a seat 16 of the fixed arm 1 established in correspondence with the upper part of the aforementioned guide hole 9. In the locked position of the tool, the spring or spring 15 is compressed, so that in the unlocking operation, that spring will help in said operation.
La distancia entre las dos mordazas 3 y 4 se puede regular ventajosamente, según las necesidades, gracias a que la mordaza móvil 4 presenta una estructura a modo de tornillo que rosca en el cilindro 12 que hace la función de tuerca, aunque también podría realizarse de forma inversa. Esta mordaza móvil 4 roscada, desempeña el mismo cometido del tornillo de ajuste convencional de este tipo de herramientas de presión. The distance between the two jaws 3 and 4 can be adjusted advantageously, according to the needs, thanks to the fact that the movable jaw 4 has a screw-like structure that threads in the cylinder 12 that acts as a nut, although it could also be made of inverse form This 4 threaded movable jaw plays the same role of the conventional adjustment screw of this type of pressure tools.
