Simultaneous dressing of electrodes in multi spot welding machines - using swivel fixture contg. row of driven grinding wheels

摘要

A device for dressing the electrodes on multi-spot welding machines, during preselected welding pauses, consists of a grinding device provided with several grinding wheels mounted on one or more shafts driven by V-belts and a motor. The device is mounted on a pivot arm so that it can be swung into the working position. A slide carrying the grinding wheels can be driven forwards and backwards between the electrodes and the grinding wheels can be moved vertically or swung on a swivel to grind the working faces of the electrodes.
