摘要

"DEVICE FOR IMPLEMENTATION OF A SYNCHRONIZED RELATIVE ROTATION BETWEEN A MECHANICAL COMPONENT AND TOOLS FOR PROCESSING IT, AROUND ECC AXIS". Device for the relative rotation of two tools (welding torches) with respect to a component of a vehicle engine discharge system, around a first and second geometrical axis of the component, parallel to each other and eccentric, for complete the same with the butt welding of two pipes located along the first and second geometrical axis; the device includes an axially symmetry support cradle for the component, within which the component may be mounted with its first coaxial geometry axis with a crib rotation axis; means for rotating the cradle about its axis of rotation by at least 360 198, first support means for the first tool located at a first radial distance from the first geometric axis, second support means for a second tool located at a second radial distance from the second geometry axis, means for rotating the second support means about the second geometry axis along a circumference having as its radius the second radial distance and transmission means for transmitting a synchronized motion of rotation from the means for rotating the cradle to the means for rotating the second support means (Figures 2 and 4)
