A groove 610 is provided on the cylindrical surface of the outside of the guide wheel 600, and the groove 610 extends in the circumferential direction of the guide wheel 600 for receiving and guiding the wire harness. The guide wheels 600 are not used alone, and a plurality of guide wheels 600 are often connected to the same wire harness, and after any guide wheel 600 is replaced, if the size of the new guide wheel 600 deviates from the size of the existing guide wheel 600, the normal production process may be affected. Particularly, in the case that the groove 610 of the guide wheel 600 has a large processing error, the wire harness cannot be centered in the groove 610 of the guide wheel 600, and an angle deviation occurs to rub the side wall of the groove 610, so that the wire harness is worn, twisted, or even broken.

Based on this, the inventor of the present application provides a guide wheel detecting device capable of detecting whether the groove 610 of the guide wheel 600 meets the use requirement, including a table top 110, and a groove-shaped detecting assembly for detecting the groove 610 of the guide wheel 600 is further provided on the table top 110, and the groove-shaped detecting assembly includes a profiling member 210 for matching with the groove 610 of the guide wheel 600.

After the central hole 620 of the guide wheel 600 is engaged with the mounting portion 312 on the rotation shaft 310, the axis of the guide wheel 600 coincides with the axis of the rotation shaft 310. Since the contact surface between the guide wheel 600 and the mounting portion 312 is a cylindrical surface, the guide wheel 600 can rotate relative to the rotating shaft 310; of course, since the rotating shaft 310 is a revolving body, the guiding wheel 600 may be driven to rotate together during the rotation of the rotating shaft 310 relative to the table top 110.

The operation of detecting the guide wheel 600 by using the guide wheel 600 detecting device provided in this embodiment includes:

the guide wheel 600 is mounted to the rotary shaft 310 of the mounting assembly, and in this process, it is determined whether the aperture of the central hole 620 of the guide wheel 600, the aperture of the structural hole 630 of the guide wheel 600, and the relative position between the structural holes 630 meet the standards.

After the guide wheel 600 is installed on the installation assembly, the extending end of the telescopic rod 240 extends out, and whether the profiling piece 210 can move into the groove 610 of the guide wheel 600 is observed in the process, so that whether an error exists in the position of the groove 610 is judged; observing whether the profiling piece 210 can be matched with the groove 610 or not to judge whether the structure of the groove 610 has errors or not; after the cam 210 is engaged with the groove 610, the guide wheel 600 is rotated, so that the guide wheel 600 is rotated around the axis of the rotation shaft 310, and the runout and roundness of the guide wheel 600 are measured.

After the guide wheel 600 is installed on the installation component, whether the bearing platform 530 is attached to the downward side surface of the guide wheel 600 or not is observed, and whether machining errors exist in the external dimension of the guide wheel 600 or not is judged; hardness of the guide wheel 600 is measured using the hardness tester 520, and it is judged whether or not the hardness of each position of the guide wheel 600 satisfies the requirement.

After the guide wheel 600 is installed on the installation component, the position of the micrometer 450 in the thickness detection component is adjusted, the thickness of each position of the guide wheel 600 is measured, and whether the thickness of each position of the guide wheel 600 meets the requirement is judged.

It should be noted that, without conflict, features in the embodiments of the present application may be combined with each other.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
