Resumen
Este trabajo expone la síntesis, materialización y control de un mecanismo de Cruz de Malta. Se parte de la necesidad de disponer de una maqueta didáctica de dicho mecanismo con bajo coste y rápida disponibilidad. Se usa el proceso de diseño de mecanismos, se obtienen sus dimensiones funcionales y sus curvas cinemáticas se grafican con el programa GNU Octave. Se aplica el paradigma de diseño para la fabricación y el ensamblaje, aprovechando la disponibilidad de una impresora 3D. Las piezas móviles se han impreso en PLA de distintos colores y la bancada se ha fabricado en madera. La modelación de las piezas y ensambles, así como la simulación del funcionamiento del mecanismo se realiza mediante SolidWorks. La maqueta incluye un motor paso a paso y su funcionamiento es controlado con una placa Arduino Uno. Como resultado se obtiene una maqueta didáctica funcional y económica, satisfaciendo la necesidad antes expuesta.
This work presents the synthesis, materialization and control of a Geneva mechanism. It is based on the need to have a didactic mock-up of this mechanism with low cost and quick availability. The mechanism design process is used, its functional dimensions are obtained and its kinematic curves are plotted with the Octave software. The paradigm of design for manufacturing and assembly is applied, taking advantage of the availability of a 3D printer. The moving parts were printed in PLA in different colors and the frame was made of wood. The modelling of the parts and assemblies, as well as the simulation of the operation of the mechanism is done using SolidWorks. The model includes a stepper motor and its operation is controlled by an Arduino Uno board. As a result, a functional and economical educational mock-up is obtained, satisfying the aforementioned need.
