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

Abstract

A position-limitable loading device used for material rigidity test includes a rack (5), a loading trolley (9) which can move left-and-right on the rack (5), and a clamping bench (11) which is fixed on the left end of the rack (5) and is used for clamping a work piece (1). An external thread sleeve cylinder (7), which is stretched into a hollow interior of a rotary shaft (6) and is threadedly matched with an internal thread ring part (71) on the left end of the rotary shaft (6), is fixedly connected to the right side of the loading trolley (9). The right end of the rotary shaft (6) is power-connected to an output shaft of a driving motor (8) that is mounted on the right side surface of a boss (51) of the rack (5). Two roller assemblies (91) are installed on the lower side of the loading trolley (9) from left to right; each of the roller assemblies (91) includes a roller that is installed with a one-direction bearing and is jointed to the rack (5).

Description

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