Environment-friendly loading device used for workpiece testing and using method thereof

Abstract

The invention provides an environment-friendly loading device used for workpiece testing. The loading device comprises a rack (5), a loading trolley (9) and a clamping bench (11), wherein the loading trolley can move left and right on the rack (5); the clamping bench is fixed at the left end of the rack (5) and is used for clamping a workpiece (1); an external threaded sleeve (7) is fixedly connected at the right side of the loading trolley (9), stretches into the hollow inside of a rotating shaft (6) and is in screw-thread 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) installed on the right side of a boss (51) of the rack (5); an electronic control device (88) is arranged on the shell of the drive motor (8), is electrically connected with the drive motor (8) and is used for controlling the rotate speed of the drive motor (8), thus being capable of controlling the rotate speed of the rotating shaft (6) as required.

Description

technical field [0001] The invention relates to the field of material testing equipment, in particular to an environment-friendly loading device for workpiece 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, ...

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
