<p>PURPOSE:To automatically inspect hardness penetration and the presence of flaws for the total number of work, by mounting a low pressure clamping device on a sensor head to press the sensor head on the work at a fixed pressure. CONSTITUTION:In a hardness penetration measuring device 11 of an inspection stage D, a constant pressure clamping device 21 composed of an air pressure cylinder 22 and a working rod 23 is provided on the back of a sensor head 17 contacting work W. After the device 21 is inserted into the work W wit an air pressure cylinder 12 from below, a pressure air adjusted to a constant pressure is supplied from a hose 24 to expand the device so that an inspecting surface 20 of the head 17 is pressed on the work W at a fixed pressure. In this manner, with the operation of two cylinders 12 and 22, the inspecting surface 20 of the head 17 is pressed automatically on the work W at a constant pressure, allowing the inspecting of hardness penetration or the like of the work W. This enables automatic and accurate inspection for the total number of work W following a hat treating stage not illustrated.</p> |
