Loading equipment for material testing and application method thereof

Abstract

The invention relates to loading equipment for material testing. The loading equipment comprises a frame (5), a loading trolley (9) and a clamping platform (11), wherein the loading trolley (9) can move left and right on the frame (5), the clamping platform (11) for clamping a workpiece is arranged at the left end of the frame (5), an outer threaded sleeve (7) is fixedly connected to the right side of the loading trolley (9) and used for extending into the hollow interior of a rotary shaft (6) and being matched with the thread of an inner-thread ring part (71) at the left end of the rotary shaft (6), the right end of the rotary shaft (6) is in power connection with the output shaft of a drive motor (8) mounted on the right sides of the frame (5) and a boss (51), a protecting cover (83) is arranged on the periphery of the drive motor (8) and fixedly connected with the right side of the boss (51) through a screw (85), and a silencing cotton layer (84) coats the inner side of the protecting cover (83).

Description

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

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
