Abstract
An electrode inspection apparatus for spot welding is provided for precisely measuring diameters of a tip of an electrode without reducing availability ratio in a production line, and is particularly useful when inspecting a weld gun having electrodes with a narrow distance therebetween. A CCD camerafor imaging the tip of the electrode held to the weld gun is disposed in an inspection apparatus body. The inspection apparatus bodyincludes a measuring reference unitin which a fixing holefor fixing the tip of the electrode is formed, and a mirrorobliquely arranged with respect to the electrode so as to be distant from the fixing holeat a position opposite to the electrode with respect to the measuring reference unit. The CCD camerais disposed in a side of the mirrorwith a distance therebetween for imaging the tip of the electrode from a direct front thereof reflected on the mirrorby reflection.
