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.

First claim

The invention claimed is:

1. A comprehensive detection tool for a steering knuckle, comprising a base, a detection pin, a sliding sleeve, a first jack screw, a positioning pin, a guide sleeve, a spring and a second jack screw, wherein a first detection section of the detection pin is matched with a left hole on the base; an inner hole of the sliding sleeve is matched with a second detection section of the detection pin;
the first jack screw is installed on the sliding sleeve, with a top of the first jack screw being matched with a sliding chute in the second detection section of the detection pin; the guide sleeve is fixed in a right hole on the base; the positioning pin is fitted into an inner hole of the guide sleeve with a fit clearance of 0.005 mm; the spring is installed inside the guide sleeve and is placed at a top of the positioning pin; and the second jack screw is installed on the guide sleeve, with a top of the second jack screw being matched with an open slot in the positioning pin;
the detection pin comprises a threaded section, a first unthreaded column section, the first detection section, a second unthreaded column section, the second detection section and a handle; wherein an upper end of the threaded section is connected with a lower end of the first unthreaded column section; a lower end of the first detection section is connected with the an upper end of the first unthreaded column section; a lower end of the second unthreaded column section is connected with an upper end of the first detection section; a lower end of the second detection section is connected with an upper end of the second unthreaded column section; and the handle is connected with an upper end of the second detection section; and
a coaxiality error between the threaded section and the first detection section is less than 0.005; a diameter of the threaded section is smaller than that of the first detection section; an edge of an upper end face of the second detection section is kept sharp; an edge of the inner hole of the sliding sleeve is kept sharp; and an upper end of the positioning pin is cylindrical and a lower end thereof is conical.
