Abstract

PURPOSE: To detect a position accurately without damaging a workpiece even in case of a touch with it due to over-movement in error allowing the use of a high- precision ball bearing as an electrode antenna and by movably holding the electrode antenna.
CONSTITUTION: Electrode antenna 6 of a ball bearing etc., movably fixed to the reverse surface of the 1st metal cylinder 7 by spring 8 and the cylinder 7 is held in the 2nd cylinder 13. Then, electrode antenna 6, embeded in the reverse surface of cylinder 7, can escape in any direction when meeting a workpiece. The reverse surface of cylinder 13 is linked with center member 14 which is provided with connector 15 with terminals 16 and 17 connected to both cylinders 7 and 13. Main shaft 32 fitted with table 24 or cylinder 13 of a machine tool is moved in order to make its antenna 6 in contact with the reference face of workpiece 23. As a result, relay 27 operates to excite alarm unit 30 and the contact point can be detected accurately.
