Mechanical device enabling profiles of the V-shaped type to be recognised automatically, especially profiles of weld lines which are to form weld seams

摘要

Fixed to a robot, where the machining tool and especially the welding torch are usually placed, is a mechanism 5 having a central element 17 able to move with four degrees of freedom and having, at its lower part, flaps 21, 22 hinged to each other in the direction of movement of the device and connected by suitable means to sensors C6, C7 so as to enable their inclination position to be determined, then two rollers 18, 19, placed on either side of the central element 17, providing the contact and guiding of the device in the profile to be recognised. <IMAGE>
