Abstract
A comprehensive detection tool for a steering knuckle includes a base, a detection pin, a sliding sleeve, a first jack screw, a positioning pin, a guide sleeve and a spring. When the comprehensive detection tool is used, under the action of the spring, the conical portion of the positioning pin contacts a reference hole B of a detected element; and the bottom surface of the base is closely clung to a reference surface A of the detected element; the threaded section of the detection pin is inserted into a left hole on the base, and then a handle is rotated to allow the threaded section to mate with the threads of the detected element.
Claims1
