One end of the module to be tested 5 is placed at a position close to the supporting table sliding groove 10, and the other end of the module to be tested is in a suspended state.
S20: adjusting the position of the bolt 3, connecting the clamp 2 with the support table 1 through the bolt 3, and fixing the module 5 to be tested on the support table 1;
after the module 5 to be tested is placed on the supporting table 1, the bolt 3 is screwed down, so that the module 5 to be tested is fixed on the upper surface of the supporting table 1.
S30: according to the size of the module 5 to be tested, the guide block 4 is moved to a preset position along the direction of the third sliding chute 201, and the clamping range of the clamp 2 is adjusted, so that the module 5 to be tested is further fixed on the support table 1;
when the bolt 3 is screwed, the module 5 to be tested is still in a semi-loose state, so that the guide block 4 slides in the third sliding groove 201 according to the specification and the size of the module 5, and moves to a proper position to adjust the clamping range of the clamp 2, so that the module 5 to be tested and the support table 1 are tightly fixed together.
S40: measuring the vertical distance from the module to be measured to the ground by using a ruler to be L1;
the surface of the module 5 to be measured is kept horizontal, so that the vertical distance of the module 5 to the horizontal ground before it is not stressed, i.e. deformed, is measured with a ruler as L1.
S50: selecting an object 6 to be placed at a corner of the module to be tested 5, which is far away from the support table 1, wherein the module to be tested 5 deforms under the pressure of the object 6;
since the risk of deformation of the module 5 is higher when pressure is applied to the corner point of the module 5 away from the support table 1, a weight 6 with a certain mass can be selectively placed at the corner point, and the module 5 deforms under the pressure of the weight 6, so that the maximum deformation of the module 5 to be measured can be measured.
S60: when the module 5 to be measured deforms under the pressure of the object 6, the vertical distance from the corner where the object 6 is placed to the ground is measured by using the ruler again and is L2;
when the module 5 to be measured deforms under the pressure of the object 6, the pressure applied to the module to be measured can be measured by measuring the pressure again by using the ruler, namely, the distance from the corner to the horizontal ground after the deformation is generated is L2.
S70: and calculating a numerical value L-L1-L2 to obtain that the maximum deformation of the module to be tested 5 is L.
The value obtained by calculating L-L1-L2 is the measured maximum deformation of the module 5, and the maximum deformation L is compared with the acceptable maximum deformation value to verify the reliability of the rigidity of the module 5 to be tested. The larger the maximum deformation L is, the smaller the rigidity of the module 5 to be tested is; conversely, the smaller the maximum deformation L is, the greater the rigidity of the module 5 to be tested is.
The invention provides a module rigidity testing device and a module rigidity testing method, wherein three groups of corresponding supporting table chutes and three groups of corresponding clamp chutes are arranged, the clamping position of a module to be tested can be adjusted according to different module testing requirements, so that the module to be tested is fixed, the maximum deformation of the module to be tested is further measured, the reliability of the module rigidity can be effectively and conveniently verified, and the module rigidity testing device is simple in structure, simple and convenient to operate and high in practicability.
