Abstract
A method and apparatus for measuring injection bores of fuel injection valves for internal combustion engines, in which the injection valve including the bores to be measured is fastened in a receiving device and the bore is measured with a measuring device. The ascertainment of the location and geometry of the bore to be measured is done by means of an optoelectronic measuring method such as a camera.
Claims8
A method for measuring injection bores of fuel injection valves for internal combustion engines, which comprise fastening an object to be measured in a receiving device, adjusting the object to be measured prior to a measuring operation by means of the receiving device in a geometrically defined position with a measuring device, ascertaining a location and geometry of the bore to be measured, during the measuring operation successively measuring inlet edges (17) and outlet edges (19) of the bore (13) to be measured by means of an optoelectronic measuring system.
An apparatus for measuring injection bores of fuel injection valves for internal combustion engines, which comprises a receiving device formed by a clamping chuck (5) that is displaced freely in three planes and is pivotable about an axis, a valve body including said injection bores is secured in said clamping chuck (5), means for illuminating said injection bores, means for directing an optoelectronic measuring device toward at least one injection bore and centering said optoelectronic measuring device along an axis of the bore measured.
