Loading device used for material rigidity testing and application method thereof

Abstract

The invention relates to a loading device used for material rigidity testing. The loading device used for material rigidity testing comprises a rack (5), a loading trolley (9) which can move left and right on the rack (5) and a clamping platform (11) which is arranged at the left end of the rack (5) and used for clamping a workpiece (1), wherein the right side of the loading trolley (9) is fixedly connected with an external threaded sleeve (7) to be inserted into hollow interior of a rotating shaft (6) and in screw thread fit with an internal screw thread ring part (71) at the left end of the rotating shaft (6), the right end of the rotating shaft (6) is coupled with an output shaft of a driving motor (8) arranged on the right side surface of a boss (51) of the rack (5) by virtue of power, two roller components (91) are arranged at the lower side of the loading trolley (9) from left to right, and each roller component (91) comprises a roller which is mounted by virtue of a unidirectional bearing and is used for being jointed with the rack (5).

Description

technical field [0001] The invention relates to the field of material testing equipment, in particular to a loading device for testing material rigidity 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 m...
