Loading device used for material rigidity test, and use method thereof

Abstract

A loading device used for material rigidity test comprises a frame (5), a loading dolly (9) arranged on the frame (5) and being able to move to the left and right, and a clamping bench (11) fixedly arranged at the left end of the frame (5) and used for clamping a workpiece (1), wherein the right side of the loading dolly (9) is fixedly connected with an external threaded sleeve (7) used for stretching to the hollow internal of a rotating shaft (6) and being in threaded fit with an internal threaded ring portion (71) at the left end of the rotating shaft (6), the right end of the rotating shaft (6) is in power connection with the output shaft of a driving motor (8) on the right side surface of a boss (51) arranged on the frame (5), the periphery of the driving motor (8) is provided with a protection cover body (83), the protection cover body (83) is fixedly connected with the right side of the boss (51) through a screw (85), and the inner side surface of the protection cover body (83) is coated with a noise reduction cotton layer (84).

Description

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

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
