Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of automobiles, and in particular relates to a handheld door-side and vehicle-body-side hinge coaxiality detection fixture and a use method thereof. Background Art
[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.
[0003] The door side hinges and body side hinges are key parts of the car. They are the key to ensuring the smooth opening and closing of the doors. At the same time, the door side hinges and body side hinges are long-term moving parts. The hinge shaft needs to rotate around the axis of the hinge seat sleeve for a long time, and the movement must be stable and reliable. The position of the hinge axis during the rotational movement is very important, which is directly related to the stability, reliability, smoothness and refinement of the door during the rotational movement.
[0004] In the existing technical solution, the accuracy of a single hinge is mainly tested by a test fixture. On the test fixture, the hinge base is fixed and the hinge axis is tested with a test pin. The existing test solution can only perform accuracy tests on a single hinge. On the actual vehicle, the door side hinge and the body side hinge are upper and lower hinges that cooperate and are used at the same time. Only when the upper and lower hinge axes are in the same straight line can the door be opened and closed smoothly. Since the existing hinge can only be tested for accuracy separately on the test fixture, it is impossible to test the coaxiality of the upper and lower hinges assembled on the actual vehicle. Even if the upper and lower hinges are qualified when tested on the test fixture, the upper and lower hinges will not be coaxial when assembled on the actual vehicle. Summary of the invention
[0005] In view of the above problems, the present invention provides a handheld door-side and body-side hinge coaxiality detection fixture and a method of use, which can simultaneously detect the accuracy and coaxiality of the upper and lower hinges, improve the detection efficiency, and thus ensure the product qualification rate.

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0027] In the existing technical solution, the accuracy of a single hinge is mainly tested by a test fixture. On the test fixture, the hinge base is fixed and the hinge axis is tested with a test pin. The existing test solution can only perform accuracy tests on a single hinge. On the actual vehicle, the door side hinge and the body side hinge are upper and lower hinges that cooperate and are used at the same time. Only when the upper and lower hinge axes are in the same straight line can the door be opened and closed smoothly. Since the existing hinge can only be tested for accuracy separately on the test fixture, it is impossible to test the coaxiality of the upper and lower hinges assembled on the actual vehicle. Even if the upper and lower hinges are qualified when tested on the test fixture, the upper and lower hinges will not be coaxial when assembled on the actual vehicle.
