Loading equipment for material rigidity test and use method thereof

Abstract

The invention relates to loading equipment for material rigidity test. The loading equipment comprises a machine frame (5), a loading dolly (9) capable of moving on the machine frame (5) leftwards and rightwards and a clamping table (11) fixed at the left end of the machine frame (5) and used for clamping a workpiece (1), wherein an external thread sleeve (7) is fixedly connected to the right side of the loading dolly (9), is used for extending into the hollow inside of a rotating shaft (6) and is in threaded fit with an internal thread ring part (71) at the left end of the rotating shaft (6); the right end of the rotating shaft (6) is in power connection with an output shaft of a drive motor (8) mounted on the right side surface of a boss (51) of the machine frame (5); a damping cushion plate (86) is arranged at the bottom of the drive motor (8); a reinforcing ribbed plate (87) is arranged between the damping cushion plate (86) and the boss (51); the damping cushion plate (86) is used for reducing the vibration force generated when the drive motor (8) runs, so that the running stability of the drive motor (8) is increased.

Description

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

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
