Abstract

Automatic installation is claimed for grinding electrodes in resistance welding plant of the type consisting of a pincer, the branches of which support each of the electrodes which grip between them the pieces to be welded and connected to a suitable electrical circuit, the pincer being carried by a robot effecting a series of movements producing a number of weld joints before reaching a position of rest for repeating the programme. Specifically, the installation comprises (i) a frame supporting a drive motor for milling cutters for grinding the electrodes; (ii) a counter for assigning a number corresponding to the number of rest position of the robot of which the electrodes must be ground; (iii) a mechanism for counting off the number of rest positions of the robot on the counter; (iv) mechanisms for ordering the opening of a supply circuit for the welder when the assigned number has been achieved; (v) appts. for initiating, in the rest position, the closure of the electrodes so as to apply the grinder cutters; (vi) a time controller for opening the circuit; (vii) appts. for sepg. the electrodes and recommencing the robot programme. The tips are automatically ground after a given number of welds has been effected.
