Description

Technical Field

[0001] The utility model belongs to the technical field of shrapnel elastic force testing, and particularly relates to a shrapnel elastic force testing device. Background Art

[0002] At present, with the continuous reduction of the size of electronic products, the corresponding components used are also getting smaller and smaller. The most commonly used component is the bending shrapnel. However, after the shrapnel is produced, it is necessary to detect whether the resilience of the shrapnel meets the design requirements. Therefore, a resilience tester is required for testing. However, at present, the handheld small resilience tester requires manual operation. The operator holds the resilience tester by hand and presses down the shrapnel, and measures the resilience according to the resilience feedback value. However, this testing method is very slow and inefficient. At the same time, the manual pressing force is unstable, which is prone to errors. Summary of the Invention

[0003] In order to solve the above technical problems, a technical solution adopted by the utility model is:

[0004] A shrapnel elastic force testing device, comprising a frame body, a clamping assembly installed on the frame body for pressing and installing a shrapnel, and a testing assembly for installing a resilience tester;

[0005] The clamping assembly includes a clamping seat plate and a first driving element for driving the clamping seat plate to slide on the frame body. At least two groups of sliding rails and sliders sliding on the sliding rails are provided on the frame body. The slider is fixedly connected to the clamping seat plate. A clamping member for clamping the shrapnel is provided on the clamping seat plate. When the first driving element drives the clamping seat plate, the clamping seat plate slides up / down on the frame body through the sliding rails;

[0006] The testing assembly includes a testing seat plate installed on the frame body and a second driving element installed on the testing seat plate. The output end of the second driving element is connected to a fixture, and the fixture is used for clamping the resilience tester.

[0007] Further, the first driving element includes a motor and a belt drive structure used in cooperation with the motor. A fixing member is provided on the belt drive structure. One side of the fixing member is fixedly connected to the clamping seat plate, and the other side is fixedly connected to the belt drive structure. When the motor is started, the clamping seat plate can be driven to move up / down.

[0008] Further, a sliding member is further provided on the frame body, and the fixing member slides on the sliding member.

[0009] Further, the clamping member includes at least two groups of pressing blocks rotatably connected to the clamping seat plate. An elastic element for resetting is provided in the pressing block. When the pressing block is pressed, the pressing block can be opened to place the elastic sheet. When the pressing block is released, the elastic element resets the pressing block to press the elastic sheet.

[0010] Further, the elastic element is a spring.

[0011] Advantages of the present utility model:

[0012] 1. The present utility model is driven by a motor to press the elastic force tester, with uniform and smooth force, avoiding manual intervention, having small test errors, and improving test efficiency.

[0013] 2. The clamping assembly of the present utility model can slide on the frame body, can adapt to elastic sheets with different elastic forces, and adjusting the height from the ground can match different elastic forces, improving adaptability. Description of the Drawings
