A quick tool alignment method and system for automatic rail weld grinding

Abstract

The present application relates to a kind of quick tool setting method and system for automatic polishing of steel rail weld, method includes: before polishing, in the case where grinding wheel does not rotate, grinding wheel is fed to steel rail, and the position of the feed motor of polishing equipment in the feeding process is recorded in real time, and the current data of feed motor in the feeding process, from the recorded data, find out the position corresponding to the feed motor when the current of feed motor exceeds the set threshold, and determine the rough polishing reference with this position as reference, that is, realize the rough tool setting of polishing reference;During polishing, in the case where grinding wheel rotates, the position of the rough tool setting is used as the starting point of accurate tool setting, grinding wheel is fed to steel rail, and the contact condition of grinding wheel and steel rail is judged by analyzing the current change of polishing motor in real time, to realize the accurate tool setting of polishing reference.The present application constructs the automatic tool setting method based on rough tool setting and accurate tool setting, can convert the tool setting process dependent on artificial into automatic tool setting process.
