Intelligent loading device for rigidity testing and use method thereof

Abstract

An intelligent loading device for rigidity testing comprises a rack (5), a loading trolley (9) which can move left and right on the rack (5) and a clamping table (11) fixed 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 thread sleeve (7) for extending into a hollow interior of a rotating shaft (6) and being matched with an internal thread ring part (71) of the left end of the rotating shaft (6) in a thread manner; the right end of the rotating shaft (6) is in power connection with an output shaft of a driving motor (8) mounted on the right side face of a boss (51) of the rack (5); the lower side of the loading trolley (9) is provided with two idler wheel assemblies (91) from left to right, and each idler wheel assembly (91) comprises an idler wheel mounted by a one-way bearing and used for being connected with the rack (5).

Description

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

Problems solved by technology

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
