Loading equipment for rigidity tests and method for applying loading equipment

Abstract

The invention discloses loading equipment for rigidity tests. The loading equipment comprises a framework (5), a loading trolley (9) and a clamping table (11). The loading trolley (9) can move left and right on the framework (5), the clamping table (11) is fixed to the left end of the framework (5) and is used for clamping a workpiece (1), an externally threaded sleeve (7) is fixedly connected to the right side of the loading trolley (9) and is used for extending into the hollow inside of a rotary shaft (6) and being in thread fit with an internally threaded ring (71) at the left end of the rotary shaft (6), the right end of the rotary shaft (6) is in power connection with an output shaft of a driving motor (8) which is mounted on the right side surface of a boss (51) of the framework (5), two roller assemblies (91) are mounted on the lower side of the loading trolley (9) from the left to the right, and each roller assembly (91) comprises rollers which are mounted by the aid of one-way bearings and are used for being connected with the framework (5).

Description

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

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
