Loading apparatus for testing rigidity and application method of loading apparatus

Abstract

The invention relates to a loading apparatus for testing rigidity. The loading apparatus comprises a stander (5), a loading cart (9) which can move left and right on the stander (5), and a loading and clamping platform (11) which is fixed at the left end of the stander (5) and used for loading and clamping a workpiece (1), wherein the right side of the loading cart (9) is fixedly connected with an outer threaded sleeve (7) which stretches into a hollow interior of a rotating shaft (6) and matched with an inner threaded ring part (71) at the left end of the rotating shaft (6) in a threading manner, the right end of the rotating shaft (6) is in power connection with an output shaft of a drive motor (8) which is installed on the right side surface of a lug boss (51) of the stander (5), the periphery of the drive motor (8) is provided with a protection cover body (83), the protection cover body (83) is fixedly connected with the right side surface of the lug boss (51) through screws (85), and the inner side surface of the protection cover body (83) is coated with a silencing cotton layer (84).

Description

technical field [0001] The invention relates to the field of material testing equipment, in particular to a loading device for rigidity testing and a method for using the same. Background technique [0002] The rigidity test of the material is an important index for the material performance of the workpiece. Materials may deform differently under different loads and thus exhibit different stiffness properties. Some existing testing equipment continuously applies gradually increasing loads to materials and measures the amount of deformation that occurs during the process. Due to the dynamic nature of load changes and the immediacy of measurement, this method is prone to cause measurement errors. For equipment with fixed value applied load, due to the discreteness of fixed value, it is difficult to obtain the point performance of expected value at any time. Moreover, slight fluctuations in the load are prone to occur during the hold of a fixed value, resulting in measuremen...

Due to the dynamic nature of load changes and the immediacy of measurement, this method is prone to measurement errors

For equipment with fixed value applied load, due to the discreteness of fixed value, it is difficult to obtain the point performance of expected value at any time

Moreover, slight fluctuations in the load are prone to occur during the hold of a fixed value, resulting in measurement errors

And although some equipment can guarantee the measurement accuracy, the cost is high and the maintenance work is complicated
