Description

Technical Field

[0001] The utility model relates to the technical field of insertion force testing, in particular to a testing tool for the insertion force of a reed nut. Background Technique

[0002] A reed nut is a very common nut in the automotive production industry and can be used in various automotive components. There are also many types of reed nuts. Besides different shapes, even the sizes are different. The functions of reed nuts are usually to tighten the force between nuts, stabilize the installation of nuts, and have a large resistance to pressure. Therefore, after the production of reed nuts, a testing tool for insertion force is needed to detect the insertion force of the reed nuts to ensure the production quality of the reed nuts.

[0003] For example, a testing tool for the insertion force of a reed nut with the Chinese patent application number CN202121824684.9 includes a base. A moving device and a moving slide are arranged on the base. The moving slide is arranged on the moving device. The moving slide includes a first moving slide and a second moving slide. The first moving slide is arranged on one side of the second moving slide. A device for fixing a workpiece to be tested is arranged on the first moving slide, and a workpiece testing device is arranged on the second moving slide. A reed nut is arranged on the device for fixing a workpiece to be tested. One end of the reed nut is connected to the device for fixing a workpiece to be tested, and the other end abuts against the workpiece testing device under the drive of the moving device. In order to prevent the reed nut from moving during the insertion force test, when the test plug gradually inserts into the reed nut, resulting in deviation of the test result, a fixed stop block is arranged on one side of the reed nut, which can limit the side of the reed nut away from the nut opening to prevent the test plug from pushing the reed nut in the insertion direction when inserting into the reed nut.

[0004] However, in actual use, when the above-mentioned reed nut is fixed by two fixing parts, during the subsequent insertion force test, the fixing parts will abut against both sides of the reed nut, hindering the insertion force test and reducing the accuracy of the insertion force test result.
