AN APPARATUS FOR DETECTION OF CORRECT SURFACE OF FRICTION CLUTCH PLATE WHILE DRILLING FROM THE PURPOSE MULTI DRILLING UNIT AND A METHOD A DOPTED THEREFOR

摘要

The present invention relates to an apparatus to detect the wrong surface of the friction clutch plate (5) while drilling, by means of a polyurethane soft pad (1) fixed on top of a steel carrier (2) and by the upward movement of the pneumatic cylinder (4) the said polyurethane soft pad (1) comes in contact with the wrong surface of the friction clutch plate (5) when a pressure contact is created against the friction clutch plate by compressed air passing through the polyurethane soft pad (1) from the hole at the side of the steel carrier (2) and air escapes through the grooves of the friction clutch plate and signals the machine operator to stop the machine and remove the friction clutch plate manually and continue the operation to run.
