Description

Technical Field

[0001] The utility model relates to the technical field of fatigue testing tooling, in particular to a double-sided rotating fatigue testing device. Background Art

[0002] like Figure 1 As shown, a hinge product connector is composed of a large plate 1 and a rotating small plate 2 connected on both sides by hinges 3. At present, the product needs to be subjected to a bilateral rotation fatigue test when it leaves the factory.

[0003] At present, the testing process is manually tested by testers, but since the bilateral rotation fatigue test requires the rotating small plates on both sides to be flipped differently for testing, the testers have high labor intensity; and the opening and closing angles of each manual flip are inconsistent, resulting in deviations in the test results, affecting the final accuracy of the test. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a double-sided rotation fatigue testing device.

[0005] The utility model adopts the following technical solutions:

[0006] A double-sided rotation fatigue testing device comprises a base, on which a workbench is fixedly mounted, on which an intermediate fixed plate for connecting a large plate of a hinge product connector is mounted, and on both sides of the intermediate fixed plate are rotatably connected flip plates, and on both sides of the base are respectively hingedly connected telescopic cylinders, and output ends of the telescopic cylinders correspond to the hinged flip plates, and on the flip plates is mounted a connecting platform for connecting a rotating small plate of the hinge product connector.

[0007] Preferably, the middle fixing plate is provided with mounting holes, which are connected to the hinge product connector plate by screws.

[0008] Preferably, the connecting platform is a magnetic connecting piece, which is connected to the hinge product connecting piece by magnetic attraction and is used to rotate the small plate.

[0009] Preferably, the flip plate is rotatably connected to the middle fixed plate via a pin.

[0010] Preferably, a support column is fixedly connected between the workbench and the base.
