Feeler head has a mounting arrangement that allows feeler pins to be interchanged but mounted in a reproducible position so that measurements on different rotationally symmetrical shapes or gear wheels can be made

摘要

Feeler head has a feeler holder (3) for a pin (2) that can be reproducibly positioned in a bearing (5) of the feeler head. A clamp (6) has a hook type end (18) that is inserted into an opening (17) of the feeler holder (3) to form a force-locked connection. The bearing (5) has at least 6 angularly distributed bearings (4) while the holder (3) has three counter-bearings (15). The feeler holder (3) can be rotated and positioned in at least two positions in the feeler head bearing (5).
