Elaboración de un prototipo de brazo robótico industrial didáctico automatizado para proceso de soldadura GMAW.

Abstract

The development of a prototype of a robotic arm welder is one of the most educational promoting teaching students and induce the knowledge of industrial robots ways. For its design and construction were consulted different robotic arms welders on the market models getting the best alternative of guide and by its required accuracy works with 6 degrees of freedom. The prototype consists of mechanical elements in its design, mostly using the aluminum structure, where his pieces were performed in a machining center. The gear transmission belonging to each of the parts of the arm were built in ABS plastic, and made of steel transmission shafts. Indispensable for operating electric and electronic elements, consists of several devices one of them stepping motors that give movement to the joints of the arm and the interface parallel port which will serve as a connection between the prototype and the computer. To order the desired movements was by G codes programming through program Linux CNC. Arm works with two power supplies, one of 110 V for the operation of the prototype and other 220 V for the operation of the welding machine. Before you start with the handling of the prototype must be recognition of performance, all the elements that comprise it as mechanical, electrical and electronic, and these last two are always energized.
