Abstract
A probe device is disclosed for checking threaded bores in a workpiece to detect various abnormal conditions including a broken tool or probe, absence of the workpiece or bore, or the threaded condition of the bore. The probe is affixed to a transversely mounted piston which is actuated by air pressure to move the probe sideways during a phase of the probing action in which a probe tip is moved against the surface to be tested, blockage of an air outlet occurring if the surface is unthreaded. The resulting increase in air pressure is detected by a pressure switch to enable operation of a fault signal. The probe tip is slidably mounted in the main body of the probe to be moved back as the probe is advanced towards the workpiece in the initial phase of the test if a bore is absent or a broken tool is lodged therein, with porting shutting off air flow to the tip air outlet to also cause an increase in back pressure enabling generation of a fault signal.
