ABSTRACT:
An apparatus for successively automatically grinding a plurality of welding electrodes of respective spot welding machines is provided with a stand transported by a work transport conveyor of a welding line, at least one automatic dresser properly positioned on the stand and a pair of through-openings formed in the stand for properly positioning the stand with respect to a work receiving jig on which the stand is placed. The stand is initially placed on a hanger of the conveyor and transported to one of a plurality of work stations by the conveyor. At the work station, the stand is properly positioned with respect to and placed on the work receiving jig. The welding electrode of the spot welding machine located at this work station is then automatically ground by the automatic dresser. Upon completion of grinding at this work station, the stand is further transported to the adjoining work station. In this way, the welding electrodes of all the spot welding machines are successively automatically ground by the automatic dresser.
