METHOD AND ARRANGEMENT FOR INSTALLING MEASURING FEELERS

摘要

A measuring feeler is incorporated in a bore of a workpiece by surrounding it with a filling material which is softer than that of the feeler and the workpiece and by applying a compressive pressure to the softer material to cause its plastic deformation and tight engagement with the bore of the workpiece and with the temperature feeler. The feeler is installed in the bore of the workpiece by orienting a counter member or rod at the end of the bore at which the feeler end is to be exposed, positioning the feeler end to engage the rod, applying the softer material around the rod and thereafter applying pressure to the softer material from the opposite end of the bore in the direction of the rod to tightly seal the feeler and the soft material in respect to the bore of the workpiece. The softer material surrounds the measuring feeler in the form of a sleeve having an outer jacket or dimension such that it bears tightly against the workpiece in the recesses or grooves thereof.
